摘　　要：针对各类水果生长方位不规则的特点和现有单口采摘装置定位困难的问题,设计了一款手持式多方位环形剪切水果采摘机械。该装置以倒摆杆滑块作为力的传导机构,推动7把环形放置的剪刀进行剪切,可实现水果单果的快速定位和采摘。通过对伸缩杆进行力学分析,以及ANSYS软件对剪切机构进行了静力学分析,表明各项结构设计均符合要求;并利用Matlab软件对摆杆滑块行程参数进行最优化设计,使其传动性能最好。在分析其工作原理的基础上,进行了样机制作与试验,实验结果表明该装置可提高采摘效率220%以上,具有很强的理论和应用价值。Given the irregularity of growing direction varying from fruit to fruit and the difficult positioning of existing singleopening picking unit,a handheld multi-directional annular cutting fruit picking machine is specifically designed to solve these problems. In this unit,the inverted rocker slider is used as the force transmission mechanism,which can push seven scissors placed in annular arrangement to allow for fast picking of single fruit. All structural designs are proved to meet the specified requirement by performing mechanical analysis of the extensible rod,and performing static analysis of the cutting mechanism with ANSYS;The optimum design for stoke parameters of the rocker slider is carried out with Matlab. The prototype is made and tested after analyzing how the unit works. Results show that this unit can improve the picking efficiency by over 220%,with great value of theoretical and application.
