[0021] In this example, the rear support plate 4 is set as a square plate structure, and the rear support plate 4 forms a rotating mechanism with the top beam 1 through the rotating shaft 3. Through the above structure, the rear support plate 4 can rotate around the rotating shaft 3;
[0022] Two second hydraulic lifting and retracting rods 8 are symmetrically arranged about the center of the bottom plate 7, and a 45° inclined plate-shaped structure is arranged at the right end of the bottom plate 7. Through the above structure, the position of the top beam 1 can be easily changed up and down by the second hydraulic lifting and retracting rods 8;
[0023] The outer surface of the movable slider 11 is set to be smooth, and the movable slider 11 is slidably connected with the connecting plate 13 through the groove opened on the connecting plate 13. Through the above structure, it is convenient for the movable slider 11 to move freely on the connecting plate 13.

[0026] Working principle: When the device needs to be used, place it at the location where mining is required. Figure 1 The support seat 19 in the middle is placed on the ground, so that the second hydraulic lifting and retracting rod 8 starts to work. At this time, the second hydraulic lifting and retracting rod 8 drives the top beam 1 to move upward, the receiving plate 9 starts to rotate around the rotating shaft 3, and the top beam 1 and the front support beam 2 start to support the coal seam, and then the first hydraulic telescopic rod 6 also starts to work, because Figure 2 The first hydraulic telescopic rod 6 is connected to the rear support plate 4 through the rotating block 5, so under the action of the first hydraulic telescopic rod 6, the rear support plate 4 begins to rotate around the rotating shaft 3, and mining can be carried out at this time. When it is necessary to move the position of the top beam 1 and the front support beam 2, the third hydraulic telescopic rod 12 starts to work, that is, the third hydraulic telescopic rod 12 drives the moving slider 11 connected thereto to move to the left. Because the moving slider 11 is installed at the lower end of the bottom plate 7, the bottom plate 7 also starts to move to the left, that is, the bottom plate 7 drives the top beam 1 and the front support beam 2 to move to the left. At this time, mining can be carried out at different positions, and there is no need to frequently move the device. It is more convenient and practical. When it is necessary to fine-tune the height of the device, the rotating Figure 1 The adjusting screw 15 is connected to the support seat 19 through the bearing installed on the support seat 19, and the adjusting screw 15 is connected to the mounting plate 14 through the threaded hole opened on the mounting plate 14. Therefore, as the adjusting screw 15 rotates, the mounting plate 14 starts to move up and down, that is, the height of the top beam 1 and the front support beam 2 is moved up and down, thereby facilitating the mining of coal seams of different thicknesses.
