This paper takes the mechanical structure of MG500/1180-WD coal mining machine as an example,this article introduces an optimization measure scheme for the mechanical structure of coal mining machine.This plan has made improvements to the cutting drum,rocker arm,and height adjustment mechanism.After improvement,the cutting module and rocker arm module have optimized parameters such as blade lift angle,intercept distance,and tooth installation angle.The height adjustment mechanism is controlled through PID control system,which significantly improves the performance of the entire coal mining machine and reduces the wear rate of the mechanical structure.This is beneficial for the safe and stable operation of the coal mining machine and has guiding significance for the optimization of modern coal mining machine mechanical structure.
