摘要

Abstract

In order to further improve the accuracy and stability of the longitudinal feeding mechanism of vegetable pot seedling automatic transplanter,a four-link longitudinal feeding mechanism driven by CAM link and sector gear was proposed.First of all,by analyzing the process of longitudinal disk feeding,the design requirements and overall scheme of the mechanism were determined,the ideal longitudinal disk feeding trajectory was planned,the comprehensive model of longitudinal disk feeding mechanism trajectory was established,and the preliminary solution was carried out by genetic algorithm.Then,based on Matlab GUI,the visualization computer aided optimization analysis software of the vertical disk feeding mechanism was developed,and the design parameters of the vertical disk feeding mechanism satisfying the design requirements were obtained.Finally,the structure design,simulation analysis and test verification of the longitudinal disk feeding mechanism were carried out.The results showed that the actual trajectory of the test was basically consistent with the theory and simulation trajectory.When the transplanting efficiency was 80 plants/(min·row)and 90 plants/(min·row),the single feeding error of the mechanism was within±1.5 mm,and there was no cumulative error after multiple feeding.At the same time,it was observed that the longitudinal feeding mechanism and the seedling taking mechanism were well coordinated through the seedling taking test,which verified the rationality of the mechanism design.
