[0038] Working principle: When using the device, first start the motor 7 fixed in the fixed box 9. After the motor 7 is started, it will drive the gear 6 to rotate. Since the gear 6 and the rack 3 are meshed and connected, the rotation of the gear 6 will drive the rack 3 to move up and down. When the rack 3 moves up and down, it will drive the cylinder 2 10 fixed at the bottom of the rack 3 to move up and down. The up and down movement of the cylinder 2 10 will drive the anchor 4 fixed to move up and down. In this way, the anchor 4 will be in contact with the ground when moving downward, and will finally be fixed in the soil. In this way, the lower baffle 1 is fixed to the ground. The design of the lower baffle 1 increases the contact area with the ground, increases the stability of the lower baffle 1, effectively prevents the side leakage of the filling material, ensures the filling quality, and provides better support for the fixed baffle, enhances the stability of the structure, reduces the risk of collapse, ensures the safety of the operation process, and protects the lives of the miners.

[0039] Since the filling bracket has a lifting function, the upper baffle 206 also needs to have a lifting function, and the bracket tube 12 and the bracket tube 2 14 constitute a filling bracket structure, the lifting process of the upper baffle 206 is as follows: when the bracket tube 2 14 rises, it will drive the upper baffle 206 fixed on the protective cap 16 to move upward, and at this time the upper baffle 206 will drive the connecting rod 3 205 to slide backward, and the sliding of the connecting rod 3 205 will drive the connecting plate 2 204 to move forward and rise upward, and at this time the connecting plate 204 will drive the connecting plate 1 202 to move forward and rise When it needs to be lowered, the bracket pipe 2 14 moves downward, the upper baffle 206 moves downward, the upper baffle 206 drives the connecting rod 3 205 to move forward, and the connecting rod 3 205 moves forward to drive the connecting plate 2 204 to move backward. When the connecting plate 204 moves backward, it drives the connecting plate 1 202 to move backward, thus achieving descent, thus achieving lifting and lowering. The lifting function flexibly adjusts the height of the baffle, improves the filling efficiency, can effectively prevent the leakage of filling materials, ensures the safety of the mine, and the lifting design facilitates maintenance and overhaul, and reduces downtime.
