本科生畢業(yè)論文（設(shè)計）題目精密大豆播種機學(xué)院機電工程學(xué)院專業(yè)班級農(nóng)業(yè)機械化及其自動化07級2學(xué)生姓名XXX指導(dǎo)教師XX撰寫日期：2011年5月10日I摘要我國的農(nóng)業(yè)生產(chǎn)及農(nóng)業(yè)機械化發(fā)展較快，化肥產(chǎn)量及施肥量逐年增加，播種機械化及播種同時施種肥的要求與日俱增。本文主要是針對我國普遍撒播的碳銨等易潮解、粘結(jié)，易揮發(fā)、易分解的肥料而對排肥機械結(jié)構(gòu)進行的改進設(shè)計。通過一些已有記錄的和進行的實驗數(shù)據(jù)而設(shè)計改進了振動攪龍式排肥結(jié)構(gòu)。這種排肥結(jié)構(gòu)主要是由肥箱、肥箱底座、振動板、撥輪、螺旋排肥攪龍和肥量調(diào)節(jié)板組成，其結(jié)構(gòu)基本原理是肥料在受到振動板振動的作用下，而在箱內(nèi)形成肥料流。這樣的結(jié)構(gòu)能使肥料不易發(fā)生堵塞、架空和結(jié)塊。這種排肥結(jié)構(gòu)適合我國的排肥機械農(nóng)業(yè)現(xiàn)狀，有益普遍推廣。關(guān)鍵詞：肥量調(diào)節(jié)板，撥輪-凸輪，振動板，排肥器IITheSubjectofUndergraduateGraduationProjectofHEAUAbstractChinasagriculturalproductionandrapiddevelopmentofagriculturalmechanization,fertilizersandfertilizerproductionincreasedyearbyyear,sowingandplantingmechanizationkindsoffatwhileincreasingdemandforfacilities.Thisarticleisforgeneralbroadcastoftheammoniumbicarbonateandsoeasytodeliquescence,bond,volatile,decompositionofmanureandfertilizerontheschedulefortheimprovementofthemechanicalstructuredesign.Somehavebeenrecordedbytheexperimentaldataandisdesignedtoimprovethevibrationoffertilizerauger-typestructure.Thisstructureismainlyoffertilizerfromthefertilizerbox,fertilizertankbase,vibrationplate,trackwheel,screwaugeroffertilizerandmanurevolumecontrolpanels,thestructureofthebasicprincipleissubjecttovibrationplatefertilizerundertheactionofvibration,andinformedinsidethefertilizerflow.Suchastructurecannoteasilycloggedfertilizer,overhead,andagglomeration.ThestructureoffertilizerforagriculturalmachineryinChinascurrentsituationoffertilizer,goodforgeneralpromotion.KeyWords：Fatvolumecontrolboard；JogDialcam；vibrationplate,；fertilizerapparatusIII目錄1引言.12種肥簡介.12.1固態(tài)種肥的分類及施用方法.11.2肥料特性.32排肥器.42.1排肥器性能要求.42.2排肥器的種類及特點.42.2排肥器的選擇.92.3振動式排肥器的設(shè)計要求.112.3.1調(diào)
