双向螺旋辊打瓜推瓜装置的设计机械电气工程学院本科毕业论文题目:双向螺旋辊打瓜推瓜装置的设计院(系):机械电气工程学院专业:机械设计制造及其自动化学号:姓名:指导教师:完成日期:双向螺旋辊打瓜推瓜装置的设计双向螺旋辊打瓜推瓜装置的设计第1页摘要新疆种植打瓜产量占全国种植打瓜总产量的75%左右,打瓜已成为我区主要的经济作物之一。随着人工收获的成本的增加,打瓜的机械化收获已成为必然趋势。打瓜收获机械的研究设计显得格外重要。本文从介绍打瓜收获机械发展现状入手,分析国内外打瓜收获机械工作原理及优缺点等,结合对本地区的实际情况,以打瓜推瓜集条为设计对象,重点设计双向螺旋辊式打瓜推瓜装置。本文首先介绍了些打瓜收获机械及其工作原理,对其各自的特点、优缺点进行了总结。进一步对几种典型的集条装置进行深入分析、对比,再结合本地区的实际现状,确立打瓜集条的总体设计方案。之后根据实际的设计参数,设计出双向螺旋辊打瓜推瓜装置的核心部件。即螺旋辊组件设计、机架的设计和传动系统的设计。最后使用Solidwoeks软件对设计的方案进行三维建模。直观立体的展现设计方案。最终对其核心部件进行强度校核。本文的强度校核主要从所给的设计参数出发,对变速齿轮箱输出轴的强度、机架的强度和螺旋叶片的强度进行校核,使所设计的机具能够满足实际使用要求,同时又能够不浪费材料。本文最后对此次设计进行了总结。关键词:双向螺旋辊;打瓜集条;机架;双向螺旋辊打瓜推瓜装置的设计第2页AbstractXinjiangplantingmelonproductionaccountsforaboutplantingmeloncountry'stotaloutputof75%,melonhasbecomeoneofthemajorcashcropsinourregion.Withtheincreaseofthecostofharvesting,melonmechanizedharvestinghasbecomeaninevitabletrend.Melonharvestingmachineryresearchdesignisparticularlyimportant.Thispaperdescribesthedevelopmentstatusdozenmelonharvestingmachinery,analyzingdomesticandmelonharvestingmachineryworksandtheadvantagesanddisadvantages,combinedwiththeactualsituationintheregiontopushmelonmelonsstripesetforthedesignoftheobject,focusingontwo-waydesignspiralrollplaypushmelonmelonmeans.Thispaperintroducessomemelonharvestingmachineryandhowitworks,itsowncharacteristics,advantagesanddisadvantagesaresummarized.Furtherseveraltypicalsetofstripmeansin-depthanalysis,comparison,andthencombinedwiththeactualstatusoftheregion,theestablishmentofmelonsetoftheoveralldesign.Aftertheactualdesignparameters,designatwo-wayspiralcoremembermelonmelonmeanspushingroller.Thatspiralrollerassemblydesign,chassisdesignanddrivesystemdesignFinally,usingSolidworkssoftwareforthedesignofthree-dimensionalmodelingprogram.Intuitivethree-dimensionaldisplaydesign.Ultimatestrengthcheckitscorecomponents.Thisarticlefromthestrengthcheckofthedesignparametersofthegivenpointofview,thestrengthoftheoutputshaftofthegearbox,chassisstrengthandintensityofthehelicalbladetobechecked,sothattheequipmentcanbedesignedtomeetthepracticalrequirements,butalsobeabletodonotwastematerial.Finally,thispapersummarizesthedesign.Keywords:Two-wayrollerscrew;Melonpiecesset;frame双向螺旋辊打瓜推瓜装置的设计第3页目录摘要.....................................................................................................................1Abstract.......................................................................................................................2第一章绪论................................................................................................................41.1研究背景..................................................................................................................41.2研究的目的与意义..................................................................................................41.3国内外研究现状......................................................................................................51.4论文研究的主要内容..............................................................................................8第二章双向螺旋辊推瓜装置的总体设计方案............................................................92.1打瓜集条的介绍......................................................................................................92.2圆盘式集条..............................................................................................................92.3单向辊式集条..........................................................................................................92.4双向螺旋辊式集条方案的确立............................................................................132.5设计参数................................................................................................................15第三章双向螺旋辊推瓜装置的核心部件设计..........................................................163.1机架设计................................................................................................................163.2传动齿轮箱的设计................................................................................................173.2.1传动比分配..................................................................................................173.2.2传动齿轮箱的设计.......................................................错误!未定义书签。73.3螺旋辊组件设计....................................................................................................223.4其他部件的设计....................................................................................................283.4.1地轮的设计.................................................................................................283.4.2四连杆的设计.............................................................................................29第四章核心部件的强度校核....................................................................................304.1连接杆的强度校核................................................................................................304.2螺旋辊轴的强度校核............................................................................................31第五章总结与展望...................................................................................................345.1工作描述.....
