Ⅰ題目：小型電動(dòng)割草機(jī)的設(shè)計(jì)摘要伴隨隨著社經(jīng)濟(jì)的快速發(fā)展，我國對園林建設(shè)，社區(qū)綠化越來越重視。農(nóng)村現(xiàn)代化建設(shè)也足部加快，目前我國大部分地區(qū)的農(nóng)村基本上都是人工收割牧草，雜草。隨著國家經(jīng)濟(jì)的快速發(fā)展，大多數(shù)青壯年選擇外出務(wù)工，家中基本上留下的基本上是空巢老人和留守兒童，收割牧草雜草比較困難，操作一些割草機(jī)工作比較困難，導(dǎo)致很多土地荒廢，雜草眾多。隨著經(jīng)濟(jì)與社會(huì)的發(fā)展，電動(dòng)收割機(jī)成為必不可少的工具，加上農(nóng)村地形地貌情況特殊，勞動(dòng)力受限，交通受限，小型電動(dòng)割草機(jī)的研究具有重大的意義，小型電動(dòng)割草機(jī)的市場需求會(huì)逐步加大。伴隨新型農(nóng)村合作社的發(fā)展，小型電動(dòng)割草機(jī)的研究前景廣闊。本設(shè)計(jì)針對山川丘陵地區(qū)，結(jié)合農(nóng)村牧草收割工作，地形地貌，勞動(dòng)力水平設(shè)計(jì)出的一個(gè)小型便利的割草機(jī)。收集查閱相關(guān)文獻(xiàn)，以及生活中所接觸和見識的內(nèi)容，主要設(shè)計(jì)割草機(jī)的工作機(jī)構(gòu)和其傳動(dòng)方式作業(yè)方式等。確保其能順利方便的完成工作。關(guān)鍵詞：割草機(jī)；牧草；設(shè)計(jì)；機(jī)械制造ⅡAbstractWiththerapiddevelopmentofsocialeconomy,ourcountrypaysmoreandmoreattentiontogardenconstructionandcommunitygreening.Themodernizationofruralareashasalsoaccelerated.Atpresent,mostoftheruralareasinourcountryarebasicallyartificiallyharvestedforpastureandweeds.Withtherapiddevelopmentofthenationaleconomy,mostfarmerschoosetogoouttowork,andtheirfamiliesarebasicallyemptynestelderlyandleft-behindchildren.Itisdifficulttoharvestgrassandweeds,anditisdifficulttooperatesomelawnmowers,resultinginalotoflandwaste.Withthedevelopmentofeconomyandsociety,electricharvestershavebecomeanessentialtool.Inadditiontothespecialrurallandconditions,limitedlaborforceandlimitedtraffic,theresearchonsmallelectricmowersisofgreatsignificance,andthemarketdemandforsmallelectricmowerswillgraduallyincrease.Withthedevelopmentofnewruralcooperatives,theresearchprospectofsmallelectricmowersisbroad.Thispaperdesignsasmallandconvenientmowerforgrassharvestinginruralareasinmountainousandhillyareas.Collectandconsultrelevantdocuments,aswellasthecontentscontactedandseeninlife,mainlydesigntheworkingmechanismofmoweranditstransmissionmode,operationmode,etc.Toensurethesmoothandcon
