Kinematics equation of fertilizer placement unit's cam mechanism was programmed by Pro/E.According to actual project and agronomic requirements,law of cam's motion angle and oscillating follower were determined,and then,theoretical contour curve,working contour curve and curvature radius curve was obtained.Three-dimensional model and motion simulation of cam were carried out in Pro/E and UG,and displacement,velocity and acceleration diagrams were obtained.Performance of this mechanism was verified through field experiments,the results show that there is no interference in motion mechanism,no rigid impact during the motion of roller and cam,which accord with the law of equal acceleration and deceleration motion.The average length of fertilization is22.7 cm at elliptical area,and average fertilization spacing is 52.5 cm,which can meet the design requirements and flue-cured tobacco planting requirements.
