组合机构在插秧机分插机构设计中的应用

传统的插秧机分插机构的设计选用单一的机构，由于其性能的限制，在设计时只能根据秧爪运动轨迹，取秧与插秧角度来设计插秧机分插机构，但分插机构的设计还应该考虑在各关键位置及各工作段时秧爪尖的运动速度，只有同时考虑这两方面的需要，才能设计出性能良好的分插机构，文章采用空间RSSR机构与平面连杆机的组合机构来实现这一目的。

Application of Combined Mechanisms on Design of Rice Transplanter

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.
