内容简介：

摘要 随着近来温室大棚的发展以及环保发展意识的日益增强，小型机的需求就显得更为重要，尤其以电力为动力装置的机械。然而目前广泛应用的播种机是以内燃机及人力为动力装置。本设计电动小型播种机 与 传统的播种机相比 .新颖之处在于播种机完全采用电力为动力装置，从而改善了人们在田间作业时的 工作 环境，况且更符合环保发展的观点。 本设计主要用于农户田间播种和设施种植播种 .增加部分装置 也 可用于施肥、耙磨、除草等田间作业。详细介绍了播种机的结构组成以及各部件的形式、要求以及功用。详细介绍了电动小型播种机动力装置及各部件要求，包括 播种机的动力选择、机械传动的选择及尺寸、排种轮设计、排肥轮的设计、开沟器的设计、轴的设计、链轮的设计、其他的各部件设计以及播种机的工作要求、播种前的准备及播种机的使用等。在设计中考虑播种深度连续可调、播种行距连续可调、播种穴距可调、种子破碎率和播种均匀度符合国家标准。设计中在考虑实用的同时，兼顾经济节约，从而达到结构合理、生产成本低、能耗小、效率高，而且操作方便的目的。 关键词 ：电动 小型 播种机 nts Abstract With the development of the greenhouse and the consiousness of protecting our ervironment ,boosting up ,the apply of the powy machine becomes more important ,especially the machine with electric power .but at the present time the seeding-machine which is adopted abroadly is drived ba gad engine or man power .this kind of minitype seeding-machine knows from the conventional seeding-machine .Its novel aspect is its drive set which are drived by electric power completly ,so they will improve the work condition ,and accord with euthenics . This design is applied mostly with the farms of the farmers ,they can also used to fertilize、 abrade、 get rid of grass and so on ,when we incress some equipment .My design introduce the structure of the seeding-machine and the types of many parts 、some request an fuction .My design introduce the drive equipment of the machine and the types of many parts 、 request and fuction .My design also introduce the drive equipment of the machine and the request of the parts which consist of the selecting of the power 、 the size 、 the design of the axial 、 chain wheel 、 some other parts and so on .We must consider suiting well of the depth 、 the row spacing 、 the distance of scoop and the rate of seeds breaking up when seeding .In my design ,while thinking over applied ,I give attention to saving econmy ,consequently achieve structure in reason 、 the cost of produce lowness 、 the cost of power lowness 、 the effi
