北京林业大学本科毕业论文(设计)I移动式枝桠粉碎机设计机械设计制造及其自动化06-1肖志远指导教师：刘毅摘要随着社会经济的发展，园林绿化面积不断扩大，由此而产生的废残树枝等园林养护剩余物的数量也大量增加。现代的处理方法是将它切碎，并经发酵处理，制成有机复合肥。本课题所设计的移动式枝桠粉碎机主要用于粉碎园林绿化剩余物,要求其体积小,结构简单,移动方便和便于操作,因此在结构设计上有其特殊性.本机的机架、上盖都采用了铸件，降低了整机的重心；发动机和主轴之间通过皮带传动，缓和了载荷冲击；主轴通过两个圆锥滚子轴承与机架连接；刀盘和主轴之间采用平键联接；飞刀用垫块和螺栓固定。机架上配置有车轮,可以由牵引机械带动,适合用于城市绿化剩余物和伐区小径级木材的加工.关键词:移动式枝桠粉碎机，园林绿化，削片机，木材加工北京林业大学本科毕业论文(设计)IITheDesignofMobilebranchchipperMechanicalDesign,ManufacturingandAutomation06-1XiaoZhi-yuanSupervisor：LiuYiAbstractWiththesocialandeconomicdevelopment,people'senvironmentalawarenessandlandscapingrequirementscontinuetostrengthenandgardeningexpand,Theparkmaintenancesurplussuchaswastebranchalsoismultiplied.Thetraditionalapproachistheburningofbrokenbranches,landfill,notonlycauseenvironmentalpollution,butalsocannotmakefulluseofresources.Themodernbranchprocessingmethodiscuttingittopiecesandafterfermentationprocessing,makeittofertilizer.Itcanbeusedinthegardeningapplyingfertilizerorintheagriculture,turningwasteintowealth.Thetopicsaredesignedmainlyformobilebranchesmillresiduessuchasgardeningcrushsmallerbranchwoodorwoodchips,Requirementsofitssmallsize,simplestructure,easytomoveandeasytooperate,thereforethereisspecialtyinthedesignofstructure.Themachine'srack,aboutthetopheadhasusedthecastingtoreducethemachine'scenterofgravity,Strengthenedthestabilityofcompletemachineeffectively;Betweentheengineandthemainaxleadoptsthebelttransmissiontorelaxtheloadimpact,reducedtheharmofoverloadwhichbringsforthemajorcomponentsuchasflycutter；Theconnectionofmainaxleandrackistwocircularconeroller,topreventthemainaxlehavegreatbeating;Theconnectionofcutterheadandmainaxleisflatkey,Coordinatesclosely；Theflycutterusestheboltandcushiontobefixed,Reliableandstable,Theflycutterstretchesoutthequantitytobeabletoadjust，Andadvantageousfordisassemblingandthereplacement.Rackisequippedwithwheels,canbedrivenbythetractionmachine，Suitabletouseintheurbangreenresiduesandthetraillevellumberprocessing.Keywords:mobilebranchchipper,landscaping,chipper,woodprocessing北京林业大学本科毕业论文(设计)III目录1绪论.......................................................................................................................11.1课题研究背景，目的及其意义···············································································11.2枝桠粉碎机的分类特点及其工作原理···································································11.3国内外枝桠粉碎机的发展现状和趋势···································································31.4选题的设计思想，设计方法及改进······································································41.5预期结果·········································································································52移动式枝桠粉碎机的总体设计......................................................................................62.1枝桠粉碎机设计任务··························································································62.2普通盘式枝桠粉碎机的结构·················································································62.3盘式枝桠粉碎机的削片原理··················································································82.4本章小结·········································································································103主要技术参数的确定和计算.......................................................................................113.1生产能力的确定·······························································································113.2飞刀数量的确定·······························································································113.3切削力的计算···································································································123.3.1主切削力的理论分析与计算············································································123.3.2主切削力的经验公式·····················································································143.4切削功率的计算································································································193.4.1切削功率的计算··························································································193.4.2空载功率的计算··························································································203.5飞刀伸出量的确定·····························································································213.6本章小结········································································································214主要部件的设计计算................................................................................................224.1刀盘结构设计及尺寸的确定·················································································224.2主轴的结构设计································································································234.2.1轴的最小直径计算·······················································································234.2.2轴的结构设计······························································································244.3滚动轴承的选择·······························································································25北京林业大学本科毕业论文(设计)IV4.4带传动的计算·····················································
