振动筛式花生收获机设计摘要花生是优质食用油的主要原料，又名落花生，同时也是一种主要的蛋白质资源，具有许多加工产品和较长的产业链。它现在已经成为农产品和农业植物重组的重要增长和出口产品。花生产量在消费和出口结构不断调整与优化的不断刺激下，实现了跨越式发展。但是，国内花生机械化生产发展滞后的情况已经迫在眉睫，对于机械化生产机械的需求也是日渐增大。目前，它主要依靠手工工作。由于本人能力有限，本次设计主要从振动筛式花生收获机的工作原理入手，进行关键部件和收获机结构的设计，并进行主要部件的工作参数的计算。本花生收获机主要由挖掘铲，偏心轮，振动筛，带轮，传动装置和连杆等组成，在小型拖拉机的辅助下，能够得到牵引，其功率为11到13.2kw。每次都能够收货到2排花生，而且能够把挖出的花生进行移动，使其到振动筛。最后，花生粕倒伏的工作原理是通过传送带实现的。该花生收获机能够做到安全运行，实现高效的清土操作、较小的掉果几率等特征，它的净生产速度能够大于或等于0.1hm2/h。关键词振动筛；收获机；机械化；花生TheDesignofPeanutHarvesterVibratingSieveAbstractPeanutisthemainrawmaterialofhigh-qualityedibleoil,alsoknownasgroundnut,anditisalsoamajorproteinresource,withmanyprocessedproductsandalongindustrialchain.Ithasnowbecomeanimportantgrowthandexportproductforagriculturalandagriculturalplantreorganization.Peanutproductionhasachievedgreat-leap-forwarddevelopmentundertheconstantstimulationofcontinuousadjustmentandoptimizationofconsumptionandexportstructure.However,thelaggingdevelopmentofdomesticmechanizedpeanutproductionisimminent,andthedemandformechanizedproductionmachineryisalsoincreasing.Atpresent,itmainlyreliesonmanualwork.Duetomylimitedability,thisdesignmainlystartswiththeworkingprincipleoftheshaker-typepeanutharvester,designsthekeycomponentsandtheharvesterstructure,andcalculatestheoperatingparametersofthemaincomponents.Thepeanutharvesterismainlycomposedofanexcavatingshovel,aneccentricwheel,avibratingscreen,apulley,atransmissiondeviceandaconnectingrod,etc.Undertheassistanceofasmalltractor,itcanbehauled,anditspoweris11to13.2kw.Eachrowcanreceive2rowsofpeanuts,andcanmovetheexcavatedpeanutstotheshaker.Finally,theworkingprincipleoflodgingofpeanutsisachievedbyconveyorbelts.Thepeanutharvestercanachievesafeoperation,achievehigh-efficiencycleansoiloperations,andalowprobabilityoffallingfruit.Itsnetproductionratecanbegreaterthanorequalto0.1hm2/h.Keywordsvibratingscreen,harvestingmachines,mechanization,peanuts.目录摘要.................................................................................................................IAbstract..............................................................................................................II第1章绪论.........................................................................................................11.1研究的目的和意义.................................................................................11.1.1中国花生生产现状......................................................................11.1.2中国花生种植方式......................................................................31.1.3花生生产机械化现状..................................................................41.2研究目标与内容.....................................................................................51.3本章小结.................................................................................................5第2章花生收获装置的设计原理.............................................................
