为提高幼苗移栽质量,设计了1套双平行多杆栽植机构。为了分析和优化该机构的结构参数,建立了该机构的数学模型和运动学方程,并基于Matlab-gui编写了人机交互式程序界面。结合移栽农艺要求,建立了栽植机构运动轨迹与幼苗移栽直立度合格率的关系模型。根据仿真结果,优选了1组机构杆件长度、安装位置和初始角度等参数,并根据该参数设计和制造了幼苗移栽机样机。样机路面静轨迹和动轨迹的高速摄像试验表明,样机实际运动规律符合仿真设计要求,证明了机构设计、数学模型、软件程序和关系模型准确无误;田间试验时接苗准确率和直立度合格率均达100%,试验结果表明双平行多杆栽植机构符合幼苗作物移栽要求...

Hanging cup type transplanter is widely used because of its good protection to the seedlings, the strong adaptability to the soil and its flexibility of planting depth adjustment. In order to improve the quality of hanging cup type transplanter in transplanting seedlings, static trajectory graft seedlings test, planting perpendicularity comparison test and dynamic trajectory plant seedlings test have been designed according to the agronomic requirements. Through those tests, the relation model between the position of seedling mechanism and the accuracy of graft seedlings, the perpendicularity ...
