Abstract: The traditional design of the transplanting mechanism of rice transplanters utilized only a single mechanism,which satisfied only requirements for the assigned movement locus of the seedling claw and the angles of rice pulling and transplanting. To design a good transplanting mechanism, the movement locus of the seedling claw, the angles of rice pulling and transplanting, as well as the working speeds of the seedling claw in various key positions and working stages should all be taken into consideration. Therefore, this paper endeavours to prove the feasibility of using a combination of mechanisms to improve the performance of rice transplanters.
