简易手动球形水果采摘器设计 摘要 本课题运用制图软件对采摘器进行机构设计，可伸缩夹取式采摘机械是一种为解决人们采摘高处果实难而创新设计的工具，同时本设计大大的方便了农民工采摘油茶果的过程及采摘效率的提高。设计机构内容包括：采摘机构、可伸缩杆机构、和收集机构并用solidworks软件绘制了机构的三维图以助理解。可伸缩夹取式油茶球形果实采摘机构主要采用了采摘机携手和铝合金管可伸缩机构，采摘宽度范围较大效率高、伸缩长短可调节，采摘较灵活省力，果实由铝合金管的旁边的引导轨道滑出，最小采摘水果直径为40mm，最大采摘水果为80mm，收集极为方便省力，铝合金管可伸缩机构又使其质量较轻，便于携带，经投产和改进后可望解决农民朋友对于直径相近球形果实的采摘难题，市场前景广阔。 关键词：可伸缩性；球形水果；采摘；夹取式；机构设计。 Abstract I
