Kinematic Analysis and Simulation of Cavitation Mechanism of Tobacco Seedling Transplanter

吊篮式烟草钵苗移栽机成穴机构的作业性能直接影响移栽机的移栽质量。为了探讨成穴机构各杆件相互作用及成穴铲运动规律,针对成穴机构进行简化,建立矢量方程得到成穴机构成穴铲的位移、速度和加速度模型。采用ADAMS软件建立成穴机构的三维运动仿真模型进行仿真分析,对获得成穴铲竖直和水平方向的位移、速度及加速度变化曲线进行分析,满足成穴要求,验证了成穴机构结构设计的合理性,为烟草钵苗移栽机成穴机构的运动轨迹进一步优化及动力学仿真分析提供了理论依据。

Performance of cavitation mechanism of basket tobacco seedling transplanter directly affects the quality of to-bacco seedling transplanting. By simplifying the cavitation mechanism and establishing the vector equation, exploring the mechanism of the interaction between the various members of the cavitation mechanism and movement law of the spade and obtaining displacement, velocity and acceleration model of the spade. Using ADAMS software built into3 D motion simulation model of the cavitation mechanism and simulate. The change curves of displacement, velocity and acceleration in the vertical and horizontal direction of the spade are analyzed, and the rationality of the structure design of the hole forming mechanism is verified. It provides a theoretical basis for the further optimization and dynamic simulation analysis of the movement locus of the transplanting mechanism of tobacco pot seedling transplanting machine.
