Simulation of Upright Transplanting Based on EDEM Chain-clamped Red Peony Root Transplanter
摘要
Abstract
Aiming at the current transplanting machine can not realize the problem of upright transplanting of red peony root,drawing on the working principle of the chain-clamped transplanting machine,the kinematics analysis of red peony root landing inclination and forward speed,seedling height,seedling throwing angle as a function of,and elucidated the changing law of the seedling throwing inclination,the height of the landing and the landing inclination of the red peony root.Using simulation analysis,discrete element model for transplanting of red peony root was established,and the main influencing factors for upright transplanting of red peony root were established as the forward speed,seedling height,seedling throwing angle,seedling clamp and the horizontal distance of furrow opener,and the horizontal values of the fac-tors were analyzed;with the degree of uprightness as the index,four-factor and five-level central plane experimental de-sign and parameter optimization were carried out.The results showed that when the forward speed was 240.68 mm/s,the seedling throwing angle was 14.19°,the seedling dropping height was 145.66 mm,and the horizontal distance was 5.68 mm,the degree of uprightness of red peony root was 86.62°.The field test was conducted and the results were 82.3° of upright degree,92.9%of upright rate,and 13.6%of coefficient of variation of plant spacing.The results of field trial uprightness were basically consistent with the simulation results.This study could provide technical reference for the determination of the performance parameters of chain-clamped red peony root upright transplanter.关键词
