Abstract

Aiming at the problems such as low seeding qualification rate of vegetable precision seeder, this paper designs a kind of air-absorbing precision seeder. The device is mainly composed of chassis part, seed discharge device, power unit, fan, gearbox and transmission device. ADAMS software is used to simulate the kinematics and dynamics of the air-absorbent seed discharger, and the simulation results show the movement and falling process of the seeds inside the seed discharger, and at the same time analyze the movement and force of the whole machine. By building a test bench, the seeding qualified rate under different factors is obtained to meet the requirements, which verifies the rationality of the machine design.

针对蔬菜精量播种机播种合格率低等问题，本文设计了一种气吸式精量播种机。该装置主要由底盘部分、排种装置、动力装置、风机、变速箱以及传动装置等组成。利用ADAMS软件对气吸式排种器进行运动学和动力学仿真，仿真结果显示了种子在排种器内部运动及下落过程，同时对整机的运动及受力情况进行分析。通过搭建试验台，得到不同因素下的播种合格率均满足要求，验证了整机设计的合理性。
