毕业设计说明书中文摘要柠条联合收割机压扁及切碎装置的设计摘要：柠条是豆科锦鸡儿属的一个种,多年生长灌木植物，柠条抗旱、抗寒、耐瘠薄、耐风沙、具有极强的生命力和抗逆性。鉴于柠条独特的生物特性，多年来它一直是内蒙古西部及山西西北部和陕西、甘肃等防风固沙、防止水土流失的重要选用植物。全国柠条种植面积已达到666.66万hm2 ，仅山西大同市柠条种植面积达到2万hm2 。柠条含有丰富的蛋白质，开花期鲜柠条干物质含粗蛋白14%，粗脂肪3.5%，粗纤维39.3%，无氮浸出物31.3%，粗灰分5.4%。由此可见，柠条还是优良的经济饲料。然而由于种植柠条的地区都是生态状况较差的地区，这类地区实行了严格的禁牧舍饲圈养后，使柠条的经济价值很难体现。为了使柠条的饲用价值得到体现，可以对符合标准的柠条进行平茬作业，再进行后续加工，生产出的产品可以添加到饲料中去。但是柠条难收割这个问题在农用机械制造领域已经成为共识，现有的平茬机械切割效果差，柠条被切割后直接凌乱的散落在地里。这些机械的适应性差，很多地方还是需要人工砍切收割。由于柠条茎秆木质化较高，而且茎秆上多硬刺，人工砍割和收集都非常不容易，收割效率极低而且效果非常差。为了解决这一难题，使柠条经济价值得到更好的体现，满足广大柠条种植地区的要求，本文设计了一种柠条的联合收割机械。这款联合收割机采用65马力柴油机，首先采用链式拨禾装置把柠条拨入收割台，采用了往复式切割器对柠条进行切割，然后通过加持链条送入立式压扁输送辊系统进行压扁及输送，随后送入立式滚筒切碎系统对柠条进行切碎，切碎的柠条最终掉入滚筒下的集料箱实现茎秆的收集，实现了柠条的联合收割。整个机构中，压扁输送辊和滚筒切碎装置本次设计的重点，两部分均采用立式安装，使整体机构变的紧凑，节省了空间，与前面的往复式切割系统能够很好的配合。此柠条联合收割机的设计为柠条的联合收割提出了新的方式，为后续的设计和研究提供了一个较好的方向。其主要特点：1.联合化程度高。 2.对收割后的柠条进行了粗加工，方便后续的加工处理。关键词：柠条 联合收割机 压扁辊 滚筒切碎刀学士学位论文（设计）原创性声明

参观一拖汇德工装有限公司3月3日我们参观了一拖汇德工装有限公司。2006年，由共和国长子一拖集团有限公司工装制造厂脱胎转制而成。半个多世纪的人才和技术积淀，加之灵活规范的管理机制，和诚信创新的文化机制，造就了一个宽产品面、长服务线的现代科技企业。客户的需要就是公司的需要。汇德公司可为机械行业提供刃具、检测量具（量仪）、机床夹辅具、焊装夹具等成套工装供应，根据您的产品技术要求，提供从工艺设计、工装（含非标设备）的设计制造到使用培训服务的一揽子解决方案。具有液压元器件、专用零部件等产品的技术研发、生产制造经验和技术积累。汇德公司秉承“为客户创造价值”的理念，为您打造高品质、优性能的产品和服务，支撑您的企业快速稳定地发展。在工装厂，我们看见了我们机床上用的各种刀具的生产下线，我们见到我们平时用的多的钻头的生产过程和生产的刀具。让我们增长了许多我们课本上学不到的东西，我们也看见了各个生产的图纸，和我们在学校学习的一样。3. 参观了一拖齿轮厂3月4日我们参观了一拖齿轮厂。厂里的饿师傅给我们讲可一下该厂的有关情况，然后我们就进了车间，到这儿同样要很注意安全，各式各样的车床、机床高速旋转着，很是危险，要十分小心，到了这儿就是真的来到了一个齿轮的王国，各种各样的齿轮应有尽有，我数了几遍到底也没数出他们到底生产多少种齿轮。 在这儿我看到了很多加工齿轮的机床。4. 参观一拖动力机械有限公司3月4日我们参观了动力机械有限公司，也就是以前的第一发动机厂，该公司是中国一拖集团有限公司骨干专业公司之一，由一拖柴油机公司和第一拖拉机股份有限公司于2003年共同投资专业生产动力机械的公司。其前身为第一拖拉机股份有限公司第一发动机厂，自1958年建厂以来，已累计生产各类柴油机60多万余台。一拖动力机械有限公司主导产品为：YTR105系列柴油机、东方红4125系列涡流室柴油机、B4125J系列直喷柴油机、YT4130系列直喷柴油机及30350KW发电机组。我们刚进车间门在侧墙上就看到了公司的一些情况说明。说到急切需要发展制造技术，这是现在国内需要迫切解决的问题。说是在发动机厂里参观学习，但是发动机的制造和装配是商业秘密不给看的，我们要看的是两个重要零件的加工：曲轴和连杆。书本上看似深奥和抽象的理论在这里经过工人的操作就变得一目了然。下刀点，刀路，工件加工后的情况，工件与刀具工件与车床的相对位置，夹具的实际形状曲轴和连杆的加工工序，每个工序的装夹和定位，相关工序所用的夹具知识等等这些，看得很清楚，也容易记住，深一层懂得定位的原理，比在课堂上学容易吸收得多多。老师也说了一句一个在读研究生的话：“大学四年，就是在实习这段时间学到点东西。”很正确，起码对我来说是这样。完整地看了曲轴和连杆的加工过程，由毛坯到出厂成品。先说个感受，就是效率慢，虽然是生产线的工作，但是每一个工序都是由工人操作机床一步步完成，是单件生产的模式。也许这两个零件本来就重要，需要很高的精密度和精确度，需要这样细致的操作，但是也不觉得工作很细致，至于其他的零部件，几乎都是这样的单件生产，还没看到批量生产的设备。另外一个感觉就是落后，下午在看加工工艺卡，看了一下给我们看的卡的日期，1988年的.如何改进这些，就是我们专业要学习的知识。5.参观中信重型机械有限公司中信重型机械公司是洛阳矿山机器厂进入中国国际信托投资公司后，以洛阳矿山机器厂为核心组建的企业集团公司。公司座落在素有“九朝古都”之称的河南省洛阳市，是中国第一个五年计划期间建设的156项重点工程之一，四十多年来经过多次扩建改造，已发展成为中国最大的重型机器制造企业。公司占地面积216万平方米，拥有资产近25亿元。年机器产品产量在30000吨左右，年商品产值达8亿元。公司所属的进出口公司及工程成套公司具有优秀的专业队伍和雄厚的实力。中信重型机械公司是机械行业的八大重型企业之一，是中南地区的铸、锻及热处理中心，大型重载齿轮加工基地。中信重型机械公司是国家外贸出口自营企业，先后向美国、澳大利亚、东南亚、西欧等数十个国家和地区出口了机器装备和铸锻件。也从美国、日本、德国、瑞典、丹麦、法国等引进了一批先进技术和工艺设备。在这儿我看见了超大型零件的生产过程，许多大型的零件都是以一般来加工，这样便于运输，我们在中信工人师傅的带领下，参观了公司的大型机床，他还给我们介绍了许多大型机床，这些都是全世界少有的大型机械。在这儿我们既长了知识也饱了眼福。6. 参观一拖精密铸造厂3月6日下午，我们参观了一拖精密铸造厂，该厂是第一拖拉机股份有限公司的专业厂，具有四十年的熔模铸造生产历史，是全国最大的精密铸造厂之一。精密铸造工程机械方面的备件有各种挖掘机、装载机的斗齿、齿根、矿用钻头、铁路枕底清筛机扒掌、扒链、扒齿等，耐磨性、质量可与进口原装备件相媲美。年生产能力为3000吨。该厂技术力量雄厚，工艺装备精良。拥有全国第一条机械化制壳流水线、中频感应炉，有造型、煤气焙烧、浇注、落砂联动铸工输送器，以及从美国微软公司国进口的DV-6型直读光谱仪等先进质量检测设备等。我们进取看见工作条件也不怎么好。通过师傅的讲解和自己的观察，发现该厂主要采用熔模铸造法生产，熔模铸造的工艺流程如下：制作母模制作压型制作蜡模制作型壳脱蜡焙烧和造型浇注脱壳。熔模铸造尺寸精确，铸件表面光洁，无分型面，不必在加工或少加工。熔模铸造工序较多，生产周期较长，受型壳强度限制，铸件重量一般不超过25kg,适用于多种金属及合金的中小型、薄壁、复杂铸件的生产。7. 参观一拖工程机械有限公司3月6日我们首站参观了一拖工程机械有限公司。该公司是中国第一拖拉机股份有限公司与华晨中国机械控股公司合资经营的大型企业。公司始建于七十年代，前身为机械工业部的重型军工企业，生产规模宏大，技术力量雄厚。九三年成立合资公司以来，凭军工技术的科研能力，不断开发出符合国情和市场需求的高性能价格比的工程机械产品。先后推向市场的有：轮式装载机、工业推土机、振动压路机三大系列数十个型号产品，其中东方红T100工业推土机被评为省优质产品。作为驰名中外的“东方红”工程机械产品，行销国内三十个省市自治区，并出口到欧洲、亚洲、非洲、拉美和澳大利亚等国家和地区。精益求精、精良制造。凭借军工生产的实力，公司不仅拥有国内外著名企业制造的大型、精密、稀有的先进设备50余台，主要加工设备400余台，而且在计量、检测方面拥有国际先进水平的检测仪器，为产品质量提供了可靠的保障。

drought-resistant, cold-resistant, widely and dusty-resistant, strong vitality and Inverse-resistance. In view of the particular biological nature of Korshinsk Peashrub, it straightly grown in the west inner Mongolia, the northwest of Shanxi, Shaanxi and Gansu and it played an significant role of defending the breeze sand and keep water and soil, the total planting areas in the whole country is up to 66,666,600,000 hm2, , the planting area of Datong is already up to 200 thousand hm2,. Korshinsk Peashrub is rich in protain, in the time of anthesis, the fresh Korshinsk Peashrub contains 14% simple protein, 3.5% simple fat, 33.9% coarse fibre,31.3%nitrogen free eotrant,5.4% ash. Thus from this point, Korshinsk Peashrub is also a fine economic feed. Owning to the grown latitude of the Korshinsk Peashrub is at the area with bad ecosystem. After being carried out the Captive feeding ban, it is difficult to achieve the economic value. By way of incarnate the feeding value of Korshinsk Peashrub，we ping stubbles to the measured up and with the followed-up processing ,append into the feeding stuff finally, that Korshinsk Peashrub is difficult to reap has become a consensus in the manufacture of agriculture machinery zone. The existing mechanical cutting effect of ping stubble is poor and the cutting shrub falls under the earth directly. Those machines have bad adaptability and need to reap by manpower because of the Korshinsk Peashrub had high level of lignifications and much hard stem thorns, it is difficult to reap and collect by manpower .As a result the inefficient of harvesting and very poor effect.In order to solve this problem that make a better economic value of Korshinsk Peashrub, content the requirement of Korshinsk Peashrub planting areas, this paper project a machine of Korshinsk Peashrub Combined Harvester use 65-horsepower diesel engine and first use the chain collection conveyer device to push the Korshinsk Peashrub into the harvest; use the reciprocating cutter to cue the Korshinsk Peashrub; then through the chain conveyer into the vertical flatting and conveyer machine; send into the reciprocating tumbling-box cutting part to cut up the Korshinsk Peashrub; the cut Korshinsk Peashrub falls into the container box under the tumbling-box, eventually achieve the collection of the stem and combined-harvest. The flattened-sending roll and the cylinder cutter are installed in three-dimensional way which not only can make the whole contract well-knit but also can save the space; furthermore, it can be fully coordinated with the reciprocating cutting system. The designing of this Korshinsk Peashrub Combined Harvester not only promote a new way of combined-harvesting but also start a direction on the follow up study and research on the designing.Features: 1. The high degree of combination.2. This machine has done the rough cut of the reaped Korshinsk Peashrub which is convenient for the follow up processing.

How to prevent threshing, the method is as follows:1 and the harvest should keep linear assignment. Can easily otherwise, driving crop harvest threshing clarity is messy effect.2, should maintain threshing tooth thickness of unilateral not less than 2.5 mm. Otherwise, must change surface or update. Threshing tooth crest and inherit the gap should keep on net 3-5mm. Excessive threshing will influence, to adjust.3, often keep cutting grass the keenness of the sword. Cut grass by the side of the sword blade surface should be timely change wear or update. For grain threshing clean and create good conditions.4 the conveyor chamber, threshing and guide the clearance should be within 2mm - 0, too, should be adjusted translocated cannot enter threshing room.5, threshing depth is deep, not often adjust the threshing clarity of circumstances, should maintain proper depth, in order to reduce indoor embroiled in a threshing long stalk.6 and when the throttle should be put in the harvest, make maximum revs turned in every minute of 2000. Otherwise it will affect threshing effect. If found speed should be promptly dropped out, reduce the load inspection.7 and the crop growth, the field should be adopted, reduce speed reduced cut to reduce the load, enhance the threshing performance.Eight, the situation is unfavorable harvest: crops 55cm length less than poor too low, mechanical, crops have large difference, length of maturity, crop crop varieties of wet, difficult threshing.2 the long inefficient safe operations of rice harvesterCombine widely applied in rural areas, with the popularization of long inefficient combined harvesters, strengthen the safety production to prevent accidents, agricultural machinery safety supervision has become an important content of the work. JiShou is an important guarantee of economic benefit, therefore, must pay attention to the safety operation, the method is as follows:1, have qualified operation skills. Operators must attend technical training, familiar with and understand the performance, structure, the machines use, maintenance and operation mastering skills. Qualified through examination before operation.2, to observe the safety regulations. The safety instructions carefully study buyers on homework instructions and combine all sorts of safety warning labels.3 and safety clothing. Wear comfortable clothes, prohibit wearing headscarves, scarves, safe operations against the slippers etc.4 and security. Abide by traffic rules. Ban on others, pack accessory, avoid teasers, through the dam, could be JiGengLu culvert and etc, and can withstand prior to confirm unit weight, not pushy.5, safety and loading trucks. The ground must be flat hard, loading and unloading board must have enough strength, width, length and antiskid device and hook. Two parallel plates should be no difference, low slow. Midway cannot turn, speed and braking lest overturned, if need to be modified direction return to sender.6 and safety operation. Harvest Operators should be energetic, lack of sleep, drunk or illness of unfavorable operation. In the homework before pack good safety cover, shields, and try running shell, confirm the working parts may be put into operation. The machine before must honk or other methods to meet food and signaled that it is safe to those around. In the work, listen to observe, once produce abnormal shall immediately stopped running, promptly components.7 and safety inspection and maintenance. Harvesters in machine cleaning machine, check and adjustment should be shut out fault, when the shift lever, and for the engine should be separate each clutch. In the harvest, when should be raised overhaul safety devices will be locked or cut machine with reliable supporting things fixed, prevent the harvest of decline.8 and prevent fires. Should be on fire, fuel and oil spill to timely rub-up. Engine exhaust and battery, not allow heads up around the machine can park in the stalk of place. And no smoking.9 and prevent burns. The engine running or just stop immediately when cannot open cooling box, prevent water jet scald, subject to open after cooling.10 and safety parked. Harvesters will reap should be parked down to the ground of the lowest positions, or shut, take out the key step, engine braking under fixed, the pavement in tyre shall be put on the track or before anti-skid pad.3 the long inefficient to prevent cut sets jams rice harvester,Cutting machine is blocked in the operation of the combined harvester ommon fault, it tends to affect the normal operation of the harvester. Serious when cut machine cant work. Therefore must pay attention to the prevention work cut machine, clogging the method is as follows:1, harvest crops cannot be dry, wet, and dew. Crops in height, otherwise easily 55mm crop uprooted, clogging the chain, but also stem not threshing. Lodging should comply with the Angle of cut in 85 degrees below 70 degrees in reverse, cut the following requirements. Harvest the crops to make excessive lodging cutting machine jam. At harvest time, reduce should reduce cutting speed, watch, found that jam. Timely parking2, the harvest should as far as possible to stay straight road. To make points bending because of grain harvest stem the grass points over the crops, and deformation when conveying grain crops is messy, clogging.3 and reasonable control the feeding amount reap crops. Such high crop harvest shall be taken, reduce speed reduced cut, avoid excessive loads caused jams. After the collision stacks points should be timely deformation is restored to the correct width, prevent excessive width caused by feeding amount caused jams increase.4 should keep a sharp, sticking. Every day after harvest should remove dirt, weeds, check and adjustment, promptly replace worn sticking. Keep moving knife knife and set the gap in 0 0.5 mm.5, help to maintain good grain chain tensioner degrees. And grain, grain and stent shall promptly replace after wearing claw back to ensure crops not messy.6 and often keep claw chain belt, bluegrass, shoot, the chain chain, depth in such a state, too loose when should adjust, excessive wear should be replaced.7 and cutting machine jams cannot use accelerated forced through. So easily make driving components are damaged. The correct approach is rapid, using artificial clear the blockage of crops.4 the long chain transmission inefficient rice harvester maintenanceChain transmission is indispensable to combine the transmission mechanism. Its work or harvesters will directly affect the normal work of the components and performance, and therefore should be done in use, maintenance and repair the method is as follows:1 in shaft, wheel should be no skewed and swinging. In the same transmission components in the face of two sprockets should be located in the same plane and sprocket center distance 0.5 meters in the allowable deviation, 1 mm, Sprocket 0.5 meters above centre distance in the allowable deviation, 2 mm. But does not allow to have the friction sprocket teeth profile phenomenon, if two rounds of migration to produce large chain and accelerate wear off. In the replacement of sprocket, we must pay special attention to check and adjustment offset.2, the chain of firmness should fit, too tight increase power consumption, bearing wear, Too loose easily beat and chain chain. Chain of chain for: from central filed or press, two sprockets centre distance is about 2-3cm.3, a new chain or long after the use to adjust, can elongation, to look for the chain, but must be even. The chain should lock plate, back through the chain is inserted in the outside, lock piece at the turn of the mouth should be in the opposite direction.4 and sprocket badly worn, should also change new sprocket and new chain, in order to ensure good engagement. Not only change the new chain or new single chain. Otherwise it will cause a new chain or improperly meshed accelerate new sprocket and wear. Sprocket tooth surfaces wear to a certain degree in turn use (used to face adjustable sprocket). In order to prolong the using time.5, old and new chain chain can use, otherwise easy mixed in transmission chain, tensile impact.6, chain in work should promptly fill lube. Oil must enter roller and set in the fitting clearance, improve the working conditions and reduce wear.7 and when the machine, long-term storage chain should be removed using kerosene or diesel clean, then coated with oil or butter in a dry place, to prevent corrosion.5 the long inefficient rice harvester inter-district assignments need attentionAs a long inefficient (KUBOTA) combine professional harvest, 28% of homework is quite important. To smoothly inter-district harvest, please users must be attached to the following aspects of work.1 the preparation before operation, and develops(1) inter-district assignment information collection. Users can according to relevant state departments of information throughout the wheat and rice harvest and local agricultural information management, also may follow contact with customers, because the harvest of the local conditions are familiar with the user.(2) business contacts. On-the-spot investigation in the field conditions, crop growth and high price, etc.(3) inter-district homework route. According to the time sequence of all crops, choose as far as possible, set harvest security conditions are good, traffic is convenient.(4) machine. In order to avoid failure inter-district assignments must be done before operation expenses in inter-district before repair, comsumption products, oil etc. Such as engine oil, inferior oil market, many in the local time before to 28% of purchase. Hara& Co. inefficient(5) and vendors. Homework, route will inter-district inform vendors, carry on with the certificate (the combine harvester drivers license and id card of 28%, etc.).(6). Try to purchase related (machine, personnel) insurance.2 and develops in the homework problems that should be paid attention to(1) harvest in the operation, to avoid attention combining exertion caused by accidents due to overwork.(2) strengthen the maintenance and inspection machine, the machine always in good working condition.(3) to strengthen the supervision of machine, storage, especially to avoid machine weathered and guard against theft, prevent damage.3 and the handling problemsSuch as: (1) in the inter-district assignments harvesters malfunction, please come and maintenance service, will contact details (including harvesters fault fault components, harvest field around), damaged parts, and quantity (shows a part of components in place, serial number part), the specific location and harvesters telephone users such report maintenance personnel.(2) if you want to buy parts, can contact with long inefficient local hara& Co., company address (spare parts purchase, etc.) should be near. If you cannot buy accessories, direct contact with the seller, to discuss the required parts orders and shipping method, in the shortest possible time after receiving accessories, maintenance, continue to work.6 the maintenance long inefficient rice harvester of unidirectional clutch,The function is a one-way clutch combine harvester in advance when the power of the engine reliably transfer to combine harvester, fall off quickly, in order to realize the need of combine harvesters. In use due to improper operation, easy cause one-way clutch early wear, harvesting machine doesnt work well. Therefore, must grasp the correct use of method.1 and the drive belt should reap department regularly or adjustment, the length of a spring in 102mm, cannot too loose or too tight. Or should adjust the length of the spring.2 and combine in operation should be done in the stable power, speed, smooth junction stable steering, must not stop, accelerated, steep, hurry to, in order to reduce the shock load one-way clutch.3 and in harvest in the homework assignments to observe the harvest, cutting machine, jams that immediately after stopping harvesting clutch, separated by artificial clear all the progress of begin again after operation. Do not remove or not in blocking incomplete remove junction, clutch, so easily to harvest early damage of unidirectional clutch.4 and reasonable control the feeding amount reap crops. When high-yielding crop harvest if should be taken to cut, reduce speed reducing excess load in order to reduce the one-way clutch. After the collision stacks points should be timely deformation is returned to the correct width, in order to prevent excessive width caused by feeding amount caused jams increase.5 and the harvest of lodging crops can not force (85 degrees below for the cut and thrust to 70 degrees Celsius) cut. Lodging crops are messy, should be adopted in the harvest threshing depth, using automatic control, find out timely downtime clogging.6 and one-way clutch after damage replace. In the first should check whether the axis wear is a one-way away when the diameter of the axis wear to 18.771 mm, must change the new axis, otherwise the new one-way clutch after loaded still cannot play a role.Wheel organization function is supporting the full weight of combine harvesters, driving and harvest, it is the important system combines walking working parts. If not for the correct use and operation, maintenance, easily wheel organization early wear. Therefore must pay attention to early wear prevention. The method is as follows:1, to strengthen the wheel organization daily maintenance. Do homework after stent to load, timely, lifting, tensioner arm sticky roller and mud product, clean weed.2 and constant observation wheel load, wheel, lifting, tensioner wheel rotation condition videotapes. Find abnormal or wheel rotation, should not carefully, change bad parts, hidden faults.3, check the quantity, truck wheels lubricant should be added to the shortage of oil. Provisions Find duo-cone floating oil, should change in time to maintain good sealing.4, truck wheels, stents, lifting, tensioner wheel rim thickness should have worn thin change in time, otherwise caused by insufficient strength variant rupture, scrape.5 and driving wheel wear a tooth thickness 5mm amounted to face when using, adjustable to prolong the using life. When both tooth thickness should be promptly replace worn, otherwise it will cause sprocket and track core iron meshing impact when increases, abnormal wear iron core, serious when still can hook iron core.6 500 hours, each work regularly to walk round institutions should be thoroughly checked, repair, to achieve good technical conditions.7 and combine in road, should avoid bad roads in the road. When the crawler bottom to have cleared eyewinker. Ensure the wheel in good working environment, improve its service life.Long inefficient combine the good crop harvest lodging with benign. Under normal circumstances can harvest the crops for lodging 85 degrees below, cut cut in inverse 70s. At harvest time must pay attention to grasp the operation method under:1, should use a sharp knife sticking the sword, and the gap shall be in 0 0.5 mm.2 stacks, claws should be adjusted to height can lift crop panicle position (namely the position on a standard). To straighten up, reduce crop messy.3 stacks, and shall be transferred to high speed, and to increase the help shift position for lodging, grain number of grain crop rotary.4, harvest of transmission belt, shoot the chain chain, ear grain, should according to regulations chain tensioner, cutting machine is too loose in the harvest clogging.5, conveying chain tightly guide if wear, should adjust guide and chain of zero clearance, crop is involved, or within the cylinder threshing.6 and the cleanness of threshing regulating handle should be put on open position, to minimize threshing room load.7 and the cutting grass threshing indoor dao should be promptly replace, sharp. In order to ensure the clarity, reduce crop threshing damage grain.8 and cut in assignments platform height should keep in grain from the ground height is about 20mm. High grain can help claws, cannot fulfill the harvest. Low is easy to root crops, accelerate uprooted sticking.9 and cut width should with slightly less than normal cut width for good (usually right portion of the grain open about 200 250m m). To alleviate the harvest of load.10 and should adopt the automatic control of threshing depth, unfavorable adjustment. To minimize threshing room load.11 and the harvest of straight road, dont be keep swinging. Slow speed is not reap, jam in case.In December, when the harvest to observe operation condition, should take the first right ahead and grain threshing depth, device runs into the entrance of threshing chain and watching the sequence of operations. According to the circumstance timely adjust speed, cut width harvest threshing machine, cutting height, etc, in order to maintain good depth of operation condition.13, is not in conformity with the harvest of crops, otherwise not forced to wear, and early machine crop waste is serious.7 the combine harvester threshing rice for the inefficient maintenance1, threshing room can overload in the harvest, when high-yielding crop and speed of cutting should reduce and control the work load of the rated load operation, to prevent excessive threshing chamber of the causes.2, the harvest threshing due to lodging crops into the room to increase many weeds in the chamber pressure and threshing threshing adopts the automatic control, depth to reduce indoor excessive threshing straw into.3, correctly use the regulating handle gib threshing. When lodging at harvest crops, the regulating handle on the open position, make indoor crop threshing, reduce indoor quickly. In the threshing, grain on the small branches shall handle is placed in position, extend the time on threshing indoor crops, increase grain clarity. Usually handle position should be put in standard.4 and keep cutting grass blades, check the knife cut grass threshing indoor wear and abrasion can make crops or not cut off, retention time long, threshing ungodliness, threshing chamber pressure increases, cut grass dao in reversing or update after wear.5, conveying chain tightly compressed guide, if be the clearance of crops to easily, cause stress in threshing room greaten, must always keep checking and adjusting, chain and guide the gap with zero.Six, in use as threshing shall, when close room blocked out, after the progress of the engine can work, or forced work to cause damage to the threshing room components.8 the long inefficient rice harvester crawler maintenance instructionsRubber pedrail are self-contained combine the important parts in the mechanism, and the price is expensive. Rubber pedrail life depends in large part on work environment and method of use. Must attach importance to the early wear rubber pedrail prevention. The method is as follows:(a), pay attention to the work environment1, rubber pedrail, diesel engine should be avoided and various oil, grease, etc. Also should avoid with acid, alkali, salt, pesticide, and other chemicals. In this case. Clean,2, rubber pedrail should avoid the rocks, in sharp steel etc uneven road. When necessary, can be laid wood or other flat object.3, rubber pedrail should avoid in gravel and gravel road surface are long. This is caused extremely easily rubber surface early wear, if the driving distance, should use loaded vehicles.(2), master correct usage1, rubber pedrail use should be timely maintenance after cleaning. If after harvest in paddy field, homework every day to prevent rubber pedrail cleaning the accelerated corrosion and abrasion.2 and walk in the process of reducing.there should as far as possible. .there is caused extremely easily off track, wheel damage produced or guide wheel impact caused by core iron core iron.3, often check driving wheel, and guide roller wear. Driving wheel wear after severe driving gear meshing with iron core, when the larger gap increasing impact, serious when core iron hook. Wear serious drive wheels, guide wheel, roller etc should be promptly replace.4, not in what tilt walking on, Walk across the bridge, Step walk; edge friction Forced climb step walk etc. These abnormal driving will cause damage, the core patterns crawler iron break, crawler edge cut, steel cord was not the normal damage.(3), pay attention to the rubber pedrail degree of adjustmentRubber pedrail must always maintain normal degree. Not too loose or too tight. Tensioner force is too loose, caterpillar derailment wheel gear wheel ride, load. Zhang is too tight tight force of tension, caterpillar to track the elongation, changes in the localities, produce high surface, causing the core iron and driving wheel wear acceleration. Use often should check and adjustment. When should adjust the hard ground in flat on the ground) (cement. Use driven up frame, loosen nut, caterpillar zhang will load the gap between roller and tracked to regulations, then tighten lock nut clearance.9 the long period of idle harvesters inefficient rice maintenanceAfter the operation, combine into a store of leisure time in winter. In order to make the combined harvesters in good technical status often, for next years harvest homework to prepare. Must be carefully to combine harvester of fine seed maintenance, the maintenance. The requirements are as follows:(a), cleaning1 and after harvest with a comprehensive cleaning machine, rinse with water stick in the mud and all machines, clean water to prevent electric parts, cleaning after lt with dry cloth to wipe.2 and thoroughly clean harvest threshing, stem department, the department of residue discharged in grain, vegetable faults. When cleaning or portable power available compressor fan blowing off, usable also artificially. Do not leave any grain, vegetable faults, otherwise easily broken wire from mouse bit, electric appliances.3 and in turn the axle will be wrapped around the weeds, with the mud and cleaned. In order to reduce the resistance during operation.4 for cooling water tank, cleaning, through the steamed into the space between the radiator cooling, ventilation, to ensure the effectiveness.(2), leisure park period1 and after cleaning, cleaning machine, should according to how much time on the corresponding maintenance and repair, replacement of need and regularly check the parts according to regulations. To check the wear parts and found fault to timely repair, do not make machines in spite of long-term park.2 the paint, machine parts should be painted. The friction, rotating parts to refill oil or butter, in order to prevent rusting.3, chain should be removed using kerosene or diesel engine clean, besmear butter or attached labels on dry prevent rust.4 and relax drive belt or removed after the clean soap, attached the label in a cool and dry place to prevent deformation and corrosion.5, should be cleaned, sticking to prevent rusting deposited oil paint.6 and relax, should combine harvester crawler board should be fitted under various operating handles to corrosion, from and should be in stop, remove key switch to keep.7, in order to prevent the DongLie winter, radiator cooling should join antifreeze. Without antifreeze should put all the water, should put all the diesel fuel.Eight, the battery should be taken under the hull, electrolyte added plus specified amount, then sufficient electricity, stored in a dry place, bask in every 2 months shall charge once, such as batteries in body, must be removed anode cables.9 and machine parked place should be clean, dry, can prevent the rain, moistureproof, security, fire. And alarm and extinguishing appliances.久保田收割机维修保养一 防止久保田联合收割机脱粒不清脱粒不清是作物脱粒后，桔杆上仍留有一定数量的谷粒，或作物仍保留原状未脱粒，以及谷粒上留有较长的枝梗等现象。它是联合收割机作业中最常见的故障。怎样预防脱粒不清，其方法如下：1、收割时应保持直线作业。不能弯曲行驶收割，否则易使作物凌乱不齐影响脱粒净度。2、应保持脱粒齿单侧的厚度不小于2.5mm。否则需换面或更新。脱粒齿顶与承受网的间隙应保持在35mm。过大时会影响脱粒效果，需及时调整。3、经常保持切草刀的锋利。切草刀下侧的刀刃被磨损时应及时换面或更新。为谷物脱粒干净创造良好的条件。4、脱粒室输送链条与导轨的间隙应在02mm内，过大时需及时调整，使秸杆不能进入脱粒室。5、脱粒深浅不能经常调节过深，在不影响脱粒净度的情况下，应保持适当的深度，以减少脱粒室内卷入大量较长的秸杆。6、在收割时油门应放在最大位置，使发动机转速保持在每分钟2000转以上。否则会影响脱粒效果。如发现转速下降应及时检查排除，减少负荷。7、对作物产量高，生长密的田块宜采用减少割幅，降低车速以减轻负荷，增强脱粒性能。8、对下列情况不宜收割：作物长度小于55cm，田块高低差过大，作物长短相差较大，作物尚未成熟，作物过湿，难脱粒品种。二 久保田水稻收割机安全作业联合收割机在农村得到广泛应用，随着久保田联合收割机的普及，加强安全生产预防事故发生，已成为农机安全监理工作的一项重要内容。也是提高机手经济效益的重要保障，因此必须注意安全作业，其方法如下：1、具有合格的操作技能。操作人员须参加技术培训，熟悉和了解机器的性能、构造，掌握使用、保养、作业等技能。经考核合格后方可操作。2、遵守安全规章。认真学习购机说明书中的安全作业须知和联合收割机上的各种安全警告标签。3、安全着装。禁止穿宽松衣服，扎头巾、围巾，穿拖鞋等不利于安全作业的着装。4、安全转移。遵守道路交通规则。禁止搭乘他人，收起辅助部件，避免急转弯，在通过堤坝、便桥、涵洞、机耕路等应事先确认能否通行和承受机组重量，切勿冒进。5、安全上下装卸卡车。地面要平硬，装卸板须有足够的强度、宽度、长度且有防滑装置和挂钩。两板应平行，没有高差，低速慢行。中途不能转向、变速、刹车以免翻车，若需修正方向应退回原处调整。6、安全收割作业。操作人员应精力充沛，睡眠不足、酒后、生病等不宜操作。在作业前装好安全盖板、防护罩壳，并进行试运转，确认各工作部件运转正常方可投入作业。机器在开动前须鸣喇叭或用其他方法向接粮人员和周围人员示意确认安全才能工作。在作业中注意观察、倾听，一旦发生异常应立即停止各部件运转，及时进行排除。7、安全检查、维修。收割机在进行机内清扫，机器检查、调整、排除故障时应关停发动机，变速杆为空档，各离合器应分离。收割部在抬高检修时，应将安全装置锁定或将割台用可靠的支承物固定，防止收割部下降。8 、防止火灾。机上应备有灭火器，燃油、机油溢出时要及时擦净。发动机排气管和蓄电池周围不允许草屑堆积，机器不能停放在秸杆堆积的地方。并禁止吸烟。9、防止烫伤。发动机在运转中或刚停机时绝对不能立即打开散热箱盖，以防沸水喷出烫伤，须经冷却后才可打开。10、安全停放。收割机停放时应将收割部下降至地面或最低位置，关停发动机，取出钥匙，踏下固定刹车，在倾斜路面上应在轮胎或履带前后放上防滑垫块。三久保田水稻收割机防止割台堵塞割台堵塞是联合收割机在作业中的常见故障，它往往影响收割机的正常作业。严重时割台无法工作。因此必须注意做好割台堵塞的预防工作，其方法如下：1、收割的作物应干燥，不能过湿、露水较多。作物高度需在55mm以上，否则容易使作物连根拔起，堵塞茎端链条，而且也不易脱粒。倒伏角应符合顺割在85度以下，逆割在70度以下的要求。收割过度倒伏的作物易使割台堵塞。在收割时应减少割幅，降低车速，注意观察，发现堵塞及时停车清除。2、收割时应尽可能保持直线行驶。因弯曲作业易使分禾器的分草杆把待收割的作物压倒变形，造成扶禾器输送时作物凌乱，发生堵塞。3、合理控制收割作物的喂入量。如收割作物产量过高时应采取减少割幅、降低车速，避免负荷过大而造成堵塞。分禾器碰撞变形后应及时恢复到正确的宽度，防止宽度过大造成喂入量增加而引起堵塞。4、割刀应保持锋利。每天收割结束后应清除泥土、杂草，检查、调整，及时更换磨损的割刀。保持定刀与动刀的间隙在00.5mm。5、扶禾链需保持良好的张紧度。扶禾支架盖、扶禾爪磨损后应及时更换以保证作物搬送不凌乱。6、经常保持爪形皮带，扶禾链、茎端链、穗端链、深浅等处在良好的张紧状态，过松时应及时调整、磨损过大应更换。7、割台堵塞时不能采用加大油门强行通过。这样极易使传动构件损坏。正确做法是迅速停机，用人工清除被堵塞的作物。四 久保田水稻收割机传送链条的保养链条传动是联合收割机中不可缺少的传动机构。它的工作好坏将直接影响到收割机各部件的正常工作和性能发挥，因此在使用中应做好维护与保养，其方法如下:1、链轮装在轴上应没有歪斜和摆动。在同一传动组件中两个链轮的端面应位于同一平面内，链轮中心距在0.5米以下时，允许偏差毫米；链轮中心距在0.5米以上的时，允许偏差2毫米。但不允许有摩擦链轮齿侧面现象，如果两轮偏移过大容易产生脱链和加速磨损。在更换链轮时必须注意检查和调整偏移量。2、链条的松紧度应适宜，太紧增加功率消耗，轴承易磨损；太松链条易跳动和脱链。链条的松紧程度为：从链条的中部提起或压下，两链轮中心距约为23cm。3、新链条过长或经使用后伸长，难以调整，可看情况拆去链节，但必须为偶数。链节应从链条背面穿过，锁片插在外面，锁紧片的开口应朝转动的相反方向。4、链轮磨损严重后，应同时更换新链轮和新链条，以保证良好的啮合。不能只单独更换新链条或新链轮。否则会造成啮合不好加速新链条或新链轮的磨损。链轮齿面磨损到一定程度后应及时翻面使用（指可调面使用的链轮）。以延长使用时间。5、旧链条上不能与部分新链条混合使用，否则容易在传动中产生冲击，拉断链条。6、链条在工作中应及时加注润滑油。润滑油必须进入滚子和内套的配合间隙，以改善工作条件，减少磨损。7、机器长期存放时，链条应拆下用煤油或柴油清洗干净，然后涂上机油或黄油存放在干燥处，以防锈蚀。五久保田水稻收割机跨区作业需要注意事项作为一个拥有久保田(KUBOTA)联合收割机的专业收割户，跨区作业是相当重要的。为了能够顺利的进行跨区收割，请用户务必做好以下几方面的工作。1、跨区作业前的准备(1)跨区作业信息的收集。用户可以根据国家有关部门编发的全国小麦、水稻收割信息与当地农业管理部门取得联系，也可以跟随老用户一同进行收割作业，因为老用户对当地情况比较熟悉。(2)业务联系。实地考察田块条件、作物生长高度和收割价格等。(3)跨区作业路线。依据各地作物成熟时间先后顺序，设定收割路线，尽量选择治安条件较好、交通便利的地区。(4)机器准备。为了在跨区作业中尽量避免故障，一定要在跨区作业前做好农忙前检修，及时补充易耗品、油料等。如发动机机油，市场上的劣质油很多，故应在跨区作业前到当地久保田代理店购
