Motion Simulation and Mechanical Analysis of Key Components of Machine-picking Cotton

为了满足棉花生产全程机械化的要求,项目组研发了适用于在耕整后田地上作业的2BMJ-3A型基于机采棉的智能精量播种机。为此,对2BMJ-3A型基于机采棉的智能精量播种机的结构和工作原理进行了介绍,利用三维设计软件Solid Works和机械系统动力学分析软件ADAMS对播种机的仿形播种机构进行了运动学仿真,并利用Solid Works中的Simulation模块对播种开沟器进行了有限元分析。结果表明:在耕整后的田地上,播种机仿形播种机构的仿形能力能够满足棉花播种的要求,播种开沟器在工作状态时不会产生屈服现象,能够满足棉花播种的使用要求。

In order to meet the full mechanization of cotton production requirements,the project team developed for the field after the tillage in the work of 2BMJ-3A-based intelligent machine precision cotton seeding machine. In this paper,the structure and working principle of 2BMJ-3A intelligent precision planter based on machine-picked cotton are introduced. The kinematics simulation of the planter seeding mechanism of the seeder was carried out by using the 3D design software Solid Works and the mechanical system dynamic analysis software ADAMS. The simulation of the seeding opener was carried out by using the Simulation module in Solid Works. The results showed that the profiling ability of the planer sowing mechanism of the planter could meet the requirement of cotton seeding in the field after tillage,and the sowing device could not produce yield in the working state and meet the requirement of cotton planting.
