本科生毕业论文（设计）题目＿＿精密大豆播种机＿＿＿＿＿学院＿＿机电工程学院＿＿＿＿＿专业班级＿农业机械化及其自动化07级2学生姓名＿＿XXX＿＿＿＿＿指导教师XX撰写日期2011年5月10日I摘要我国的农业生产及农业机械化发展较快，化肥产量及施肥量逐年增加，播种机械化及播种同时施种肥的要求与日俱增。本文主要是针对我国普遍撒播的碳铵等易潮解、粘结，易挥发、易分解的肥料而对排肥机械结构进行的改进设计。通过一些已有记录的和进行的实验数据而设计改进了振动搅龙式排肥结构。这种排肥结构主要是由肥箱、肥箱底座、振动板、拨轮、螺旋排肥搅龙和肥量调节板组成，其结构基本原理是肥料在受到振动板振动的作用下，而在箱内形成肥料流。这样的结构能使肥料不易发生堵塞、架空和结块。这种排肥结构适合我国的排肥机械农业现状，有益普遍推广。关键词肥量调节板，拨轮凸轮，振动板，排肥器IITheSubjectofUndergraduateGraduationProjectofHEAUAbstractChinasagriculturalproductionandrapiddevelopmentofagriculturalmechanization,fertilizersandfertilizerproductionincreasedyearbyyear,sowingandplantingmechanizationkindsoffatwhileincreasingdemandforfacilities.Thisarticleisforgeneralbroadcastoftheammoniumbicarbonateandsoeasytodeliquescence,bond,volatile,decompositionofmanureandfertilizerontheschedulefortheimprovementofthemechanicalstructuredesign.Somehavebeenrecordedbytheexperimentaldataandisdesignedtoimprovethevibrationoffertilizeraugertypestructure.Thisstructureismainlyoffertilizerfromthefertilizerbox,fertilizertankbase,vibrationplate,trackwheel,screwaugeroffertilizerandmanurevolumecontrolpanels,thestructureofthebasicprincipleissubjecttovibrationplatefertilizerundertheactionofvibration,andinformedinsidethefertilizerflow.Suchastructurecannoteasilycloggedfertilizer,overhead,andagglomeration.ThestructureoffertilizerforagriculturalmachineryinChinascurrentsituationoffertilizer,goodforgeneralpromotion.KeyWordsFatvolumecontrolboardJogDial–camvibrationplate,fertilizerapparatusIII目录1引言..............................................................12种肥简介..........................................................12.1固态种肥的分类及施用方法........................................11.2肥料特性........................................................32排肥器...........................................................42.1排肥器性能要求..................................................42.2排肥器的种类及特点..............................................42.2排肥器的选择....................................................92.3振动式排肥器的设计要求.........................................112.3.1调量板.......................................................122.3.2拨轮凸轮...................................................122.3.3肥箱.........................................................133结语...........................................................14参考文献...........................................................15致谢................................................错误未定义书签。附录一排肥部分装配体图...........................................16附录二播种机整体装配图...........................................17
