摘要在该篇文章中，主要针对我国国内和国外的水果分级分选机进行了相应的研究，并且分析了其具有的发展现状，从而设计出更为完善的水果分级分选机。其主要是由三个部分组成，首先是传动机构，其次是分级滚筒，最后一个部分即为关键性的部位电动机。对于整个机构来说，它进行运作需要的动力主要来源于电动机，接着再凭借带轮传动机就可以把相应的动力与运动输送到分级滚筒中，这样就能够完成水果的分选。该水果分级分选机构相比于其他同类型的机器，有这几个较为显著的优点，首先是操作简单，其次是开展维护工作的难度较低，能够有效的提升工作效率，从整体上增强劳动强度，对于水果加工行业来说，能够促进其规模化的发展和机械化程度的提升。关键词：水果；形状；分选机构；分级滚筒AbstractThispaperanalyzesthepresentsituationoftheChinesedomesticandforeignfruitsortingmachineresearchanddevelopment,onthefutureprospects,wedesignanewtypeoffruitsortingmechanism.Thefruitsortingmachineiscomposedofgradingcylinder,transmissionmechanismandamotor.Thepowerprovidedbyamotor,throughabeltpulleytransmissionmechanism,themovementandpoweristransmittedtothestraighttoothcylindricalgearreducer,andthenthroughthechainwheeltransmissionmechanism,therequiredmovementandpoweristransmittedtotheclassificationonthedrum,therebywecanrealizetheseparationoffruit.Theentiremechanismissimpleandeasytooperate,easytomaintain,improveproductionefficiency,reducelaborintensity,whichhelptoachievethefruitprocessingmechanizationandscaleandtoprovidethepremise.KeyWords:fruit;shape;thegradingmechanism;gradingcylinder目录摘要......................................................................1Abstract..................................................................2第1章绪论...............................................................11.1选题研究意义.......................................................11.2国内外水果机械化发展概况...........................................11.3国内水果机械化未来发展方向.........................................21.4目前国内常见的水果分选机主要有以下几种类型.........................2第2章总体方案的拟定.....................................................32.1原理分析...........................................................32.1.1方案选择.....................................................32.1.2方案的比较...................................................42.2总体结构设计......................................................52.2.1总体结构.....................................................52.2.2传动路线.....................................................52.3各执行机构主要参数的计算..........................................62.3.1滚筒设计.....................................................62.3.2滚筒孔眼总数的确定...........................................62.3.3滚筒直径D、长度L以及各级排数P和各排孔数Z的确定............72.3.4各级筛孔数的计算.............................................72.3.5转速n及水平倾角a的确定.....................................102.3.6滚轮和摩擦轮................................................112.3.7功率计算....................................................122.3.8筛孔的设计..................................................122.3.9选择电动机..................................................132.4传动装置的运动和动力参数的计算...................................142.4.1各传动装置的总传动比及各轴转速的计算的计算..................142.4.2各轴输入功率的计算..........................................142.4.3各轴转矩的计算.................
