椭圆齿轮行星轮系蔬菜钵苗自动移栽机构运动机理分析

摘要

A rotary transplanting mechanism with planetary elliptic gears used to transplant seedlings for automatic vegetable transplanter was described. Work principle and structural features of the mechanism were analyzed. The kinematics model was established. Based on Visual Basic 6. 0, the software of aided analysis and parameters optimization for rotary transplanting mechanism were developed. Kinematics property was analyzed and simulated. Though conversations in human-computer, structural parameters of the transplanting mechanism were optimized and meet the demands of transplanting seedlings. Finally, 3-D mechanism model and simulation analysis were carried out, and the results of simulation accorded with theoretical analysis.%简述了椭圆齿轮行星轮系蔬菜钵苗自动移栽机构,分析了该机构的工作机理和结构特点,建立了该机构的运动学模型.基于Visual Basic 6.0开发了该移栽机构计算机辅助分析与优化软件,通过人机交互方式优化出满足蔬菜钵苗自动移栽机构工作要求的结构参数,最后进行了机构三维建模与仿真,仿真结果与理论分析结果一致.
