摘　　要：基于水稻插秧机的基础上改进的小型蔬菜移栽机,移栽的核心工作部件是采用曲柄摇杆的后插式分插机构,其性能决定移栽质量,通过理论分析,建立曲柄摇杆分插机构的运动模型,模拟了相对运动轨迹和绝对运动轨迹。运动VB软件获得运动轨迹,并进行参数优化,获得取苗角=13.2°,推苗角=68.08°,两角差值=55.50°。绝对运动轨迹高度达到300 mm,满足蔬菜移栽农艺要求,为蔬菜移栽设计提供理论依据。To improve small vegetable transplanter on the basic of rice transplanter,the core component of transplanting used crank rocker of plug transplanting mechanism,and the performance decided transplanting quality. Based on the theory analysis,the paper built motion model of crank and rocker transplanting mechanism and simulated the relative motion path and absolute motion path.The software VB got trajectory,optimized parameter and obtained seedling angle 13.2°,and pushed seedlings angle 68.08° and corners difference 55.50°.The height of absolute trajectory was 300 mm to meet the agricultural requirement of vegetable transplanting and provide the theory basis for vegetable transplanting design.
