[0027] specific implementation plan
[0028] In the actual environment, the different cutting trajectories of the shearer will cause changes in the terrain on the moving path, so the paths that need to be passed each time for moving and moving are different and uneven. In order to simulate this complex ground condition and make the experimental device adapt to this change and operate, the designed experimental device is equipped with a height-adjustable foot cup on the base of the hydraulic support. The height adjustment of the foot cup can change the inclination of the base of the hydraulic support. Simulate the initial posture of the hydraulic support under actual ground conditions. In addition, a rubber layer with a high similarity to the coal seam is equipped at the bottom of the scraper conveyor, and the irregular ground in the real environment is simulated through the undulating state of the rubber layer. The structure and parameters of the experimental device are close...
