Abstract:

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.
