| 摘 要： | 针对传统推秧机构存在的推秧结束时间提前或滞后问题，提出了基于共轭凸轮的强制推秧新型机构。该新型推秧机构由共轭凸轮实现推秧杆的推出和缩回。根据椭圆齿轮行星系驱动机构及插秧农艺要求构造了推秧杆的运动学曲线，建立了该推秧机构反求模型，并基于Visual Basic 6.0编写了该推秧机构的反求设计及仿真软件，反求得到一组满足农艺要求的较优参数，包括机构参数和凸轮廓线。主副凸轮最大压力角都小于许用压力角，表明该新型机构能很好地满足推秧机构效率和受力要求。

| Abstract: | In order to solve the problems of traditional seedling-pushing mechanism whose ending time of seedling-pushing was advanced or delayed, the compulsory seedling-pushing mechanism based on the conjugate cam was proposed . This novel seedling-pushing mechanism realized pushing out and retractating the seedling-pushing rod by the conjugate cam mechanism. According to kinematic curves of the seedling-pushing rod which were got from the driving mechanism with planetary elliptic-gear trains and requirements of planting agriculture, the reverse solution model of the seedling-pushing mechanism was established. A reverse design and simulation software of this seedling-pushing mechanism was compiled based on Visual Basic 6.0, and a set of optimum parameters which could satisfy the requirements of planting agriculture were obtained by the software, including the mechanical parameters and the profile of the conjugate cam. The maximum pressure angles of the master cam and the vice-cam were smaller than the allowable pressure angles, which indicated that this new kind of mechanism could meet the efficiency and stress requirements of seedling-pushing mechanism. |
