Through the analysis of the structure and working principle of hydraulic height adjustment mechanism of shearer, the linkage relationship between hydraulic system execution cylinder and shearer rocker arm is reasonably simplified, and the simplified linkage analysis is carried out by means of simplified linkage analysis, and the relationship between hydraulic system execution cylinder and shearer rocker arm is reasonably simplified. In this paper, the mathematical model of hydraulic height adjustment system of shearer is established. By using AMEsim and Matlab simulation analysis software, the mechanical-hydraulic joint simulation and analysis model of the mechanism is established, and the working process of the mechanism is simulated and analyzed. The results show that the mechanical-liquid characteristics of the shearer's height-adjusting system can be simulated intuitively by the method of combined simulation and analysis, and the design water of the coal-winning machine can be raised. It is of great significance to optimize the system structure and improve the economy of shearer use.
