Abstract: At present, fruit harvesting is more manual work, accounting for about 40% of the total industry workload. Labor costs are large, and there are safety risks to workers as well. A medium-sized fruit picker was designed, which used a motor to drive the tyre movement, and the gripper drived its rotation. Through the finite element analysis (FEA) of the strength and rationality of the mechanical structure of the part, a feasible design scheme of the channel drop fruit picking device was obtained. The design aligned with relevant regulations, had the advantages of being reasonable and feasible, easy to operate, low cost, effectively reduced the risk of fruit manual picking, reduced the labor intensity, so was significant to ensure timely harvest of fruits and improve fruit quality.

摘要： 目前，水果采摘多为人工作业，约占整个产业工作量的40%，人工成本过大，同时存在安全隐患。设计了一种水果中型采摘器，该采摘装置利用平台电机带动轮胎移动，抓手通过电机带动其旋转进行抓取。通过有限元分析零件力学结构的强度以及合理性，得出了可行的通道掉落式水果采摘装置设计方案。该设计符合相关规范、合理可行、操作简便、成本较低，有效降低了水果采摘的危险性，为实现辅助果农进行平地水果采摘奠定基础，并对降低果农劳动强度、保证果品及时采收、提升果品质量等具有非常重要的意义。
