【Abstract】 Transplanting mechanism with planetary spur gears and non-circular gear was developed, in which planetary gear train with eccentric gears and non-circular gear is used. The mathematical model of eccentric gear and non-circular gear′s pitch curve was established and the gear pitch curve equation was obtained. Combining the KISSSOFT with MATLAB software to design the non-circular gear, kinematic models of the transplanting mechanism are established, and optimized the parameters of the mechanism by using self-compiled packages based on MATLAB. Virtual prototype simulation in ADAMS was performed after finishing the 2D and 3D design of the transplanting mechanism. The static trajectory and dynamic trajectory of the needle tip are obtained, and compared these with those of theoretical analysis. The results verify the feasibility of transplanting mechanism with planetary spur gears and non-circular gear which was applied on transplanter.更多还原
