摘　　要：论述了一种免耕播种防堵装置——仿形爪式清茬机构的工作原理,推导了轮爪上任一顶点的运动轨迹、速度和加速度方程并给出了相应计算机绘图,分析了该机构的参数对工作性能的影响。结果表明:运动偏角δ宜在20°～40°之间选取,运动偏角δ比爪轮半径R对清茬机构工作幅宽影响大,轮爪宜采用后倾的布置形式。Work principle of a new anti-blocking mechanism for no-till planting was described.Equations about the trajectory,the absolute velocity and the acceleration of any vertex on the finger wheel were deduced.Associated graphics were constructed by software,and parameters of the device were analyzed.The results indicated that the movement angles δ was chosen between 20°～40°and had great influence on working width compared with radius of the finger wheel.Backward inclined distribution should be adopted for the finger.
