漿果采摘機(jī)的設(shè)計(jì)說(shuō)明書(shū).doc

I摘要現(xiàn)在農(nóng)業(yè)采摘已采用專(zhuān)業(yè)化、集約化和規(guī)?；烧?，農(nóng)業(yè)采摘機(jī)成為當(dāng)今世界最具活力的新興農(nóng)業(yè)機(jī)械之一和現(xiàn)代農(nóng)業(yè)機(jī)械的亮點(diǎn)。結(jié)合我國(guó)農(nóng)業(yè)生產(chǎn)的實(shí)際需要，針對(duì)漿果采摘機(jī)農(nóng)業(yè)機(jī)械市場(chǎng)的特點(diǎn)，對(duì)漿果采摘機(jī)進(jìn)行了研究、開(kāi)發(fā)，設(shè)計(jì)研制出一種可自動(dòng)完成對(duì)漿果的采摘及收獲的機(jī)械。課題從漿果采摘機(jī)原動(dòng)部分及傳動(dòng)部分的設(shè)計(jì)、工作部分的設(shè)計(jì)、液壓系統(tǒng)的設(shè)計(jì)等多方面詳細(xì)介紹了研究過(guò)程與方法，并給出了安裝及維護(hù)的注意事項(xiàng)。本設(shè)計(jì)以拖拉機(jī)作為原動(dòng)機(jī)，通過(guò)拖拉機(jī)的拖拽，實(shí)現(xiàn)了漿果采摘機(jī)的行駛功能，液壓馬達(dá)為動(dòng)力源，采用四連桿機(jī)構(gòu)實(shí)現(xiàn)了采摘機(jī)的采摘功能。針對(duì)不同的農(nóng)業(yè)地況，車(chē)體設(shè)計(jì)成可升降的結(jié)構(gòu)。關(guān)鍵詞：漿果采摘機(jī)；結(jié)構(gòu)設(shè)計(jì)；理論計(jì)算IIAbstractNowagriculturalpickinghasadoptedspecialized,intensiveandlarge-scaleagriculturepicking,pickingmachinebecomestheworldsmostdynamicemergingagriculturalmachineryandmodernagriculturalmachinerywindow.WithChinasagriculturalproductionactualneed,accordingtoberrypickingmachineagriculturalmachinerymarketcharacteristics,theberrypickingmachineundertookresearch,development,designanddevelopaautomaticcompletionoftheberrypickingandharvestingmachinery.Theberrypickingmachinedrivingpartandatransmissionpartofthedesign,partofthedesignwork,thedesignofhydraulicsystemandotheraspectsdetailedintroducesthestudyprocessandmethod,andgivestheinstallationandmaintenanceofthemattersneedingattention.Thedesignoftractorasmotive,thetractordrag,realizesthedrivingfunctionofberrypickingmachine,hydraulicmotorasapowersource,fourconnectingrodmechanismisadoptedtorealizepickingmachinepickingfunction.Inviewofthedifferentagriculturalcondition,bodyisdesignedintoaliftingstructure.Keywords：Berrypickingmachine；Structuredesign；TheoreticalcalculationIII目錄摘要.IAbstract.II第1章緒論.11.1選題的意義.11.2采摘機(jī)概述.11.2.1國(guó)內(nèi)外發(fā)展情況.11.2.2采摘機(jī)的簡(jiǎn)介.21.2.3采摘機(jī)的主要用途和應(yīng)用領(lǐng)域.2第2章總體方案設(shè)計(jì).42.1總體方案確定.42.1.1旋轉(zhuǎn)式結(jié)構(gòu).42.1.2擺動(dòng)式結(jié)構(gòu).42.2方案介紹及選擇.52.2.1旋轉(zhuǎn)式采摘介紹.52.2.2擺動(dòng)式采摘介紹.52.2.3采摘方案選擇.6第3章采摘機(jī)的結(jié)構(gòu)設(shè)計(jì)及計(jì)算.73.1參數(shù)初定.73.1.1車(chē)體框架尺寸初定.73.1.2接果板總長(zhǎng)初定.73.1.3擺架機(jī)構(gòu)尺寸初定.73.2框架的材料選擇及重量計(jì)算.73.3傳輸帶鏈輪的設(shè)計(jì).83.3.1初選鏈輪齒數(shù).83.3.2確定計(jì)算功率.83.3.4計(jì)算單排鏈所能傳遞的功率及鏈節(jié)距.8IV3.3.5確定鏈實(shí)際長(zhǎng)度及中心距.83.3.6計(jì)算鏈速.93.3.7計(jì)算作用在軸上的壓軸力.93.3.8按靜強(qiáng)度校核鏈條.93.3.9潤(rùn)滑方式的選擇.103.3.10鏈輪的結(jié)構(gòu)設(shè)計(jì).103.4擺架的設(shè)計(jì).103.5軸的設(shè)計(jì)及計(jì)算.103.5.1選定車(chē)輪軸徑.123.5.2車(chē)輪軸的校核.143.5.3液壓支柱支撐軸校核.163.6軸承壽命計(jì)算.16第4章液壓系統(tǒng)設(shè)計(jì).184.1液壓系統(tǒng)的設(shè)計(jì)要求.184.2液壓系統(tǒng)的基本回路.184.3確定液壓系統(tǒng)的主要參數(shù).204.3.1初選工作壓力.204.3.2計(jì)算液壓缸的主要結(jié)構(gòu)尺寸.214.3.3液壓缸工作流量的確定.224.3.4確定液壓缸的安裝方式.224.3.5繪制液壓系統(tǒng)的工作原理圖.22第5章漿果采摘機(jī)的安裝與維護(hù).255.1安裝注意事項(xiàng).255.2維護(hù)中的注意事項(xiàng).25結(jié)論.26致謝.27參考文獻(xiàn).28VCONTENTSAbstract.IChapter1Introduction11.1Significanceoftopics11.2Pickingmachineoverview11.2.1Thedevelopmentstatusathomeandabroad11.2.2Pickingmachineintroduction21.2.3PickingmachinemainlyusesandApplications3Chapter2Schemedesign52.1Scheme52.2Comparisonofthetrin72.3Thedesignfeaturest8Chapter3Calculationoftwo-wayconveyorbeltdesign93.1Theprimaryparameters93.2drivenform93.3Calculationoftransmissioncapacity103.4Thechoiceofconveyorbelt103.4.1Checkingwiththeintensity113.4.2withtheresistancecalculation123.4.3Belttensioncalculation133.5Calculatio
