小型旋耕机的设计综述VIP免费

JIANGXIAGRICULTURALUNIVERSITY本科毕业论文（设计）题目：小型旋耕机的设计学院：工学院姓名：詹志刚学号：20080982专业：机械设计制造及其自动化年级：081班指导教师：严霖元职称：教授二○一二年四月I摘要旋耕机是在我国广大丘陵，山区，地块小，高差大，无机耕道，果园，茶园，菜地，温室大棚作业的耕耘机械。本篇毕业设计对旋耕机的国内外情况进行了说明，分析和对比，首先进行了发动机的选择，变速器的选择，部分零件的选择，传动路线的设计；然后对齿轮箱的设计和校核，关键零部件的校核；最后是工作零部件的总成。国外旋耕机设施农业耕作机械已非常成熟，作业性能稳定，功能齐全，小巧轻便。日本、荷兰、以色列等国家的产品广泛用于旋耕、犁耕、开沟、作畦、起垄、中耕、培土、铺膜、打孔、播种、灌溉和施肥等作业项目。如果有适用于中国国情的小型旋耕机问世，不但直接经济效益显著，而且还具有广泛的社会效益，其推广前景将是十分广阔的。可以大大提高中国农业的机械化水平，向农业现代化迈出坚实的一步。关键词：小型旋耕机设计IIAbstractRotarycultivatorisinourcountryvasthilly,mountainousarea,smallplot,elevation,inorganicfarmingroad,orchard,teagarden,vegetablegarden,greenhousecultivationmachineryoperation.Thegraduationdesignforrotarymachineathomeandabroadwereintroduced,analyzedandcompared,theengineoptions,transmissionchoices,partsselection,transmissionlinedesign;thenthegearboxdesignandverification,keypartsofthecheck;thelastisworkingpartsassembly.Foreignrotaryfacilityfarmingmachineryisverymature,stableworkingperformance,completefunctions,compactandlightweight.Japan,Holland,Israelandothercountries,theproductsarewidelyusedinrotarytillage,plowing,ditching,ridging,bedding,intertill,ridging,filming,punch,sowing,irrigationandfertilizationproject.IfthereisasuitableforChina'ssmallrotarytillerispublished,notonlyeconomicbenefitisobvious,butalsohasawiderangeofsocialbenefits,itsprospectswillbeverybroad.CangreatlyimprovetheagriculturemechanizationlevelinChina,toagriculturalmodernizationhastakenasolidstepforwardKeywords:smallrotarytillerdesign1目录摘要.................................................................................................................................IAbstract.........................................................................................................................II第一章前言..................................................................................................................11.1选择此课题的背景.........................................................................................11.2旋耕机的简介.................................................................................................11.3旋耕机的发展趋势.........................................................................................11.4中国未来农业机械化的展望.........................................................................2第二章旋耕机工作原理与构造..................................................................................22.1旋耕机工作原理..............................................................................................22.2旋耕机的构造..................................................................................................4第三章方案的确定......................................................................................................53.1总体设计.........................................................................................................53.2主要部分确定...........................
