为了提高油菜钵苗移栽效率与质量,设计了一种适合厢面开沟槽水平推苗移栽的栽植机构。为了分析和优化该机构的结构参数,建立了数学模型和运动学方程,并编写了基于Matlab的人机交互式程序。结合油菜钵苗水平推苗移栽的农艺要求,探讨了栽植机构运动轨迹与幼苗移栽直立度合格率的关系。研究了水平推苗移栽的运动机理,优选了栽植机构杆件长度、安装位置和初始角度等参数,并根据该参数设计了油菜钵苗幼苗移栽试验装置。进行了栽植机构运动静、动轨迹验证试验和栽苗试验,轨迹验证试验表明,样机实际运动规律符合仿真设计要求,栽苗试验表明,在行驶速度0. 4～0. 6 m/s、栽植机构循环频率在1～1. 5 Hz之间...

In order to improve the efficiency and quality of rapeseed seedling transplanting, and reduce planting cost, improve planting efficiency, realize rapeseed seedling high-speed transplanting, a set of transplanting mechanism which suitable for horizontal push seedling transplanting in grooves was designed. In order to analyze and optimize the structural parameters of the mechanism, the mathematical model and kinematics equations of the mechanism were established, and a human-computer interactive program based on Matlab was prepared. Based on the ...
