摘　　要：为提高插秧机作业效率和质量,对非圆齿轮行星轮系分插机构的运动特性进行了研究。建立了机构运动数学模型,对该机构进行了位移和速度分析,求出了机构参数对分插机构秧爪的绝对运动轨迹和速度的影响规律,为采用非圆齿轮行星轮系分插机构的高速插秧机的设计提供了理论依据。In order to improve the working efficiency and quality of the rice transplanter, the kinematics analysis of transplanting mechanism with the new non-circular planetary gears has been performed. The kinematics model of the transplanting mechanism was established by using the mathematical analysis method. The displacement and velocity of the mechanism were analyzed. The effects of the structural parameters on the path and relative velocity of the seedling claw were obtained. The analysis results are of theoretical significance to the design of the highspeed transplanter.
