摘　　要：针对工厂化种植的叶菜在收获工序中机械化水平不高、劳动强度大、耗时长、效率低等问题,以具代表性的上海青为研究对象,设计了一款以带锯切割、螺杆张紧和V型皮带传动的上海青流水线生产收割装置。基于上海青根茎切割过程的理论研究和仿真分析,确定了影响切割效果的主要因素,并试制试验样机进行正交试验,获得较优参数组合如下:带锯为光刃带锯,进给速度为0.05 m/s,切割转速为400 r/min。进行了验证试验,结果表明:切割效果好,端面平整,合格率达到88.9%,收割装置达到了高效省力的设计要求。该研究可为叶菜流水线生产中的收割设备研发提供参考。To solve the problems of low mechanization level,high labor intensity,long time consuming and low efficiency in the harvesting process of industrialized planting leafy vegetables,the representative Shanghaiqing was taken as the research object, a harvesting device with band saw cutting, screw tensioning and V-belt transmission,was designed for the production line of Shanghaiqing. Based on the theoretical research and simulation analysis of cutting process of Shanghaiqing roots,the main factors affecting the cutting effect was determined,and the prototype was trial-manufactured and orthogonal tests were carried out,the optimal combination of parameters was obtained:belt saw was no teeth,feed speed was 0.05 m/s and cutting speed was 400 r/min. The verification test results show that cutting effect is well and the end face is smooth,and the qualified rate is 88.9%. Therefore,the harvesting device meets the requirements of high efficiency and labor saving. This study can provide reference for the research and development of harvesting device in the assembly line production of industrialized planting leafy vegetables.
