摘　　要：运用ProE软件设计了一种由指辊和刀辊组合的新型复合式水田除草器,工作时可对杂草进行拉拔、埋压等复合式机械作用。应用ProE软件中的运动仿真模块对除草关键部件进行了运动学仿真,得到了机具前进速度一定时指辊的指齿顶点在3种不同转速下工作的运动轨迹,通过对运动轨迹的分析可优化除草部件的最佳转速范围。Pro/Engineer（Pro/E） was applied to design a new kind of complex paddy weeder composed of finger roller and blade roller in this paper, so that it could have both pulling and bury-pressing effects on weeds during operation. Under Mechanica module of the software, motion simulation for key parts of the weeder was done, and motion trails of the endpoints on the fingers and blads were drawn under 3 different rotational speed while the machine＇s advance velocity was set at a certain value. Through analysis on the motion trails, the best range of the weeding parts＇ rotational speed can be optimized
