Abstract S225.93; 针对梨采摘效率低且劳动强度大的问题,该文通过分析梨果实特征,并搭建剪切力测量平台,对不同品种和成熟度的梨进行果柄剪切试验,测得剪断果柄的最大剪切力为5.4 N;设计了一款操作简单且不伤果实的手动背负式梨采摘器,该手动背负式采摘器由操作执行机构通过拉索拉动采摘头,使夹爪和刀片先后动作,完成采摘;采摘完后,松开操作手柄,在复位弹簧的作用下,刀具和夹爪顺序动作,果实通过收集布袋落入果篮中;基于Recurdyn对采摘器关键部件进行仿真,得出剪切力平均为13.5 N,大于剪断果柄所需的剪切力;基于ANSYS软件对主要的受力杆件组进行强度分析,验证了所设计的采摘器强度满足要求;开展实地试验验证设计的合理性.试验表明:该手持式采摘器操作简单、舒适,采用采摘器采摘,采摘效率比人工采摘效率提高了57.1％,可以实现不同高度梨的采摘,提高了果农的采摘效率和采摘过程安全性.
