刮板式花生脱壳机设计

摘要花生不仅是世界，也是我国重要的经济与油料作物，它是世界贸易量最大的坚果商品，每年的贸易量约1000000吨。我国的花生种植面积约占世界花生种植面积的1／6，总产量占世界的1／3，是我国为数不多的具有国际竞争力的大宗农产品。发展花生生产和加工，是提高我国农业出口创汇，增加农民收入的迫切需要。花生脱壳机在减轻人们的劳动强度、提高生产率方面起到了积极作用，促进了花生加工业的发展。但是，目前国内外花生脱壳机对花生破碎率和损伤率的指标要求都比较高，超出种用籽和商品化的标准，限制了使用范围。因此，降低花生脱壳机的破碎率和损伤率仍是研制花生脱壳机的关键问题。针对花生果的物理特性设计了一种滚筒栅条式花生脱壳装置关键词：花生脱壳机;驱动机构;工作部件AbstrctPeanutsarenotonlytheworld,butalsooneofthemostimportanteconomicandoil-bearingcrops,itisthelargesttradeofnuts.Eachyear,aboutthetrade1000000tons.Ourpeanutplantingareaoftheplantingareaofpeanuts,totalTheyieldof1/3,isChina'sfewinternationalcompetitivenessofagriculturalcommodities.PeanutproductionanddevelopmentProcessing,istoimprovetheagriculturalexportincreasefarmers'income,theurgentneed.Peanutshellerineasepeople'slaborintensity,improveproductivityplays.Thepositiverole,promotethedevelopmentoftheprocessingofpeanuts.But,athomeandabroadandpeanutsForpeanutshellerrateanddamagerateofindexishigher,beyondtherequirementofuseSeedandcommercializationofstandard,limitingtheusescope.Therefore,reducingthepeanutsBrokenrateandthedamageratestillisoneofthekeyresearchpeanuts.ForblanchedPhysicalpropertiesofadrumbarsofpeanutsKeyWords:PeanutshellerDrivingmechanismWorkingpart目录前言...............................................................................................................................................51.花生脱壳概况..............................................................................................................................71.1花生脱壳加工现状...........................................................................................................71．2花生脱壳机械的发展...................................................................................................81．3花生脱壳机的研究应用现状......................................................................................131．3．1目前花生脱壳机采用的脱壳原理...............................................................141．3．2新型脱壳技术...............................................................................................151．3．3花生脱壳机械的工艺研究...........................................................................171．3．4花生脱壳机械存在的问题...........................................................................181．4花生脱壳机械研究重点..............................................................................................181．4．1提高花生脱壳机械的通用性和适应性.......................................................191．4．2提高机械脱壳率。降低破损率...................................................................191．4．3向自动控制和自动化方向发展...................................................................201．5花生脱壳机械应用前景展望.............................................................................202.刮板式花生脱壳机的结构及原理............................................................................................222．1刮板式花生脱壳机的结构.........................................................................................222．2刮板式花生脱壳机工作原理.....................................................................................233.花生脱壳机的主要部件设计.......................................................................错误!未定义书签。3．1设计前各项参数的确定.................................................................错误!未定义书签。3．1．1刮板的半径及转速初定..................................................错误!未定义书签。3．1．2刮板所需功率计算..........................................................错误!未定义书签。3．1．3传动方案拟定..................................................................错误!未定义书签。3．1．4电动机的选择..................................................................错误!未定义书签。3．1．5传动装置的运动和参数计算..........................................错误!未定义书签。3．2·V带传动设计.............................................................................错误!未定义书签。3.3轴的设计...........................................................................................错误!未定义书签。3.4刮板的结构设计...............................................................................错误!未定义书签。3.5半栅笼的设计...................................................................................错误!未定义书签。3.6箱体...................................................................................................错误!未定义书签。3.7壳仁分离装置...................................................................................错误!未定义书签。3.8机架....................................................................................................错误!未定义书签。3.9附件....................................................................................................错误!未定义书签。4花生脱壳机的正确使用..............................................................................错误!未定义书签。4.1花生脱壳机的结构特点....................................................................错误!未定义书签。4.2用好花生脱壳机的前提条件............................................................错误!未定义书签。4.3操作方法与注意事项........................................................................错误!未定义书签。小结..................................................................................................................错误!未定义书签。致谢..................................................................................................................错误!未定义书签。参考文献........
