花生起垄种植中耕除草装置设计与仿真研究OA

Weeding tool is the key working part of weeding machine,its structure and performance will directly affect the working effect of the machine.The current weeding component structure can only realize the weeding at the bottom of the ditch,but can not realize the weeding at the side of the ridge.According to the parameters of peanut planting ridge body and the actual operation requirements,a kind of copying weeding component was designed.The design of the structure can enlarge the working area,increase the function of weeding at the ridge side on the basis of the original weeding at the ditch bottom,and improve the operation performance of the machine.The structure parameters and working conditions of the copying weeding device are analyzed theoretically,and the simulation test is carried out by EDEM.The experimental results show that compared with the traditional weeding device,the soil breakage rate is increased by 21.96%,the tool coverage area is increased by 126.48%,and the working efficiency is increased by 34.12%,which verifies the feasibility of the device.
