带夹式甘薯裸苗移栽机的设计

Design of Transplanting Machine for Nude Seedling with Belt

根据甘薯苗栽植的农艺要求,设计了一种带夹式甘薯苗移栽机。介绍了移栽机的总体结构,以及主要工作部件送苗装置、插秧四连杆机构、夹苗爪的设计原理。设计了插秧四连杆机构,利用Mat Lab多元优化函数求出四杆机构的各个参数,并在Solid Works motion中进行了轨迹仿真。对甘薯苗进行了压缩实验,根据甘薯苗的力学特性设计了夹苗爪,保证苗爪可以在不伤苗的情况下将苗插入土壤。该研究为甘薯栽植机械创新研发提供了参考。

According to the agronomic requirements of sweet potato seedling planting,a portable sweet potato seedling transplanting machine was designed. The overall structure of the transplanting machine and the design principle of the four-bar linkage and clip-claw are introduced. The four-bar linkage mechanism was designed and the parameters of the four-bar mechanism were obtained by using the Matlab multivariable optimization function. The trajectory simulation was carried out in Solid Works motion. The compression experiments were carried out on the sweet potato seedlings,and the mechanical properties of the seedlings were designed. Claws,to ensure that seedling can not seedlings inserted into the soil. The research provides a reference for the innovation and development of sweet potato planting machinery.
