摘要

In order to solve the problems of wheat no-till seeders in annual double cropping area of North China Plain such as large amount of straw-covering, stubble-bulky, residue-blocking, and bad passing capacity and planting quality, the new vibrating disc no-till seeder was designed. This paper analyzed the structure and elaborated the working principle. Creo software was used to establish three-dimensional motion simulation model, and add the constraints of seeder's parts to realize the movement of seeder and its anti-blocking device. The change of displacement, velocity and acceleration of vibrating disc was obtained by simulation. The result showed that there was no collision between components of the seeder, and the main circular motion occurred in y direction, which was beneficial to cut the straw. The study provides theoretical basis for the trajectory optimization and dynamics simulation analysis of vibrating disc no-till seeder in the future.
