Abstract: With acceleration of urbanization in China and reduction of rural labor force，broccoli harvest is almost entirely dependent on human resources，so it is urgent to promote automatic harvest of broccoli.There were few studies on broccoli harvesting，and its automatic harvesting is still in experimental stage of treatment theory.CATIA software and ANSYS-Workbench were used to carry out modal and analysis.The suspension bucket for broccoli harvesting was designed，which could realize the semi-automation of broccoli harvesting and reduce labor intensity.This method could increase harvesting efficiency by 2.6 times and save half of labor force.
