摘　　要：针对现有分插机构提高转速后,增加作业效率而导致取秧针针尖速度过快,取苗时触碰秧苗后造成伤秧率较高,影响水稻的成活、生长问题,设计了一种新型高速分插机构——椭圆齿轮行星系三插臂。增加一个栽插臂后可以在不降低插秧机插秧效率的情况下减小转速,降低秧针尖的速度,减小伤苗率,通过理论推导建立了秧针运动数学模型,通过SolidWorks进行了三插臂的三维建模,利用ADAMS对其运动学进行了仿真分析,分析表明,相同作业效率下,秧针尖速度降低30%。The results of the recent separating-planting mechanism were first taken into consideration.This mechanism increased its rotational speed to improve its operational efficiency;yet by increasing the velocity of the needle of the separating-planting bar,it increased the seeding injury rates at the same time.As a result,a newly designed mechanism,as well as studies on its affect on the survival and growth of rice,was introduced.The new type of separating-planting mechanism had three separating planting bars with an elliptic plant gear system of high-performance rice transplanters.Adding an additional separating planting bar kept the high operational efficiency of the rice transplanter while slowing the rotational speed to decrease seeding injury rate.Its kinematic model was established on the basis of transmission analyses of planetary elliptic gears systems;3-D models were established by SolidWorks and the kinematics simulation was analyzed by ADAMS.Under the condition of the same operating efficiency,the speed decreased by 30%.
