北京理工大学珠海学院2020届本科生毕业设计玉米脱粒机-软件设计玉米脱粒机-软件设计摘要在玉米的生产过程中，玉米的收获工作是很关键的一部分，而在玉米收获工作过程中，玉米脱粒就是至关重要的一个环节。因此针对现今的玉米脱粒机仍存在破碎率高、脱净率低等问题，我们设计了一款低破碎率、高脱净率的玉米脱粒机。为了提高玉米脱粒机的脱净率，降低破碎率，本文介绍了玉米脱粒机的的背景和分析了国内外玉米脱粒机的发展现状，然后使用proteus软件对本次玉米脱粒机设计北京理工大学珠海学院2020届本科生毕业设计进行电路图设计和进行电路仿真，并运用AT89C51单片机对本次设计进行了程序设计。经过一系列的研究设计和改进，最终设计出来的玉米脱粒机达到我们所希望的要求。关键词：玉米脱粒机；AT89C51；电路设计；程序设计；转速；间隙CornThresher-SoftwareDesign北京理工大学珠海学院2020届本科生毕业设计AbstractIntheprocessofcornproduction,cornharvestingisaveryimportantpart,andintheprocessofcornharvesting,cornthreshingisacruciallink.Therefore,inviewoftheproblemsofthepresentcornthresher,suchashighcrushingrateandlownetremovalrate,wedesignedacornthresherwithlowcrushingrateandhighnetremovalrate.Inordertoimprovethecleanrateofcornthresherandreducethecrushingrate,thispaperintroducesthebackgroundofcornthresherandanalyzesthedevelopmentstatusofcornthresherathomeandabroad,thenusesProteusSoftwaretodesignthecircuitdiagramandsimulatethecircuitofthiscornthresherdesign,andusesAT89C51singlechipmicrocomputertoprogramthedesign.Afteraseriesofresearch,designandimprovement,thefinaldesignofcornthreshermeetstherequirementswewant.Keywords:CornThresher;AT89C51;CircuitDesign;Programming;Speed;Clearance北京理工大学珠海学院2020届本科生毕业设计目录1.前言.............................................................................................................................................................11.1设计的目的及意义..........................................................................................................................11.2国内外玉米脱粒机的发展概况......................................................................................................21.2.1玉米脱粒机的概况...............................................................................................................21.2.2国外玉米脱粒机的发展概况...............................................................................................51.2.3国内玉米脱粒机的发展概况...............................................................................................61.2.4玉米脱粒机存在的问题.......................................................................................................61.3研究内容..........................................................................................................................................61.4设计路线..........................................................................................................................................61.5本章小结..........................................................................................................................................72.玉米脱粒机控制系统的设计.....................................................................................................................82.1控制器的选择..................................................................................................................................82.1.1AT89C51介绍..............................................
