In view of the unsteady flow of hydraulic system and the unreasonable setting of key parameters of oil cylinder and ac-cumulator in the process of emergency closing of the rear bin door of the traditional shield screw conveyor,hydraulic impact and damage of mechanical components are easy to be caused.A plug-in proportional flow valve control system with pressure compen-sation is proposed.By analyzing its structure composition and the principle of the valve AMEsim model is established,and the model simulation characteristic curve are analyzed,and concluded that it has better flow stability,high control accuracy,good dynamic response,and the screw machine was established based on the simulation environment after the storehouse door AMEsim model of hydraulic system,analyses the key parameters on the system of accumulator and hydraulic cylinder storehouse door emergency shut down after the influence law of the influence law and working characteristic of proportional valve for warehouse door after screw machine hydraulic system provides the theory basis for further upgrading.
