[0040] The adjusting mechanism 3 comprises two motors 301, the side away from each other of the two motors 301 is rotatably connected with a driving gear 302, the driving gear 302 is below a driven gear 303, the side close to each other of the two driven gears 303 is fixedly connected with an extension oil cylinder 304, the bottom of the extension oil cylinder 304 is slidably connected with an extension rod 305, the two extension oil cylinders 304 are fixedly connected through a connecting rod, the motor 301 is fixedly connected with the inner wall of the connecting plate 201, the two driving gears 302 are on the side away from each other of the two connecting plates 201, the two extension oil cylinders 304 are between the two connecting plates 201, the extension oil cylinder 304 is on the side close to the rotating frame 111 of the goods shelf 101, the bottom of the extension rod 305 is rotatably connected with the rotating frame 111;

[0041] The position of the docking rack 101 is adjusted by the cooperation of the driven gear 303 and the telescopic oil cylinder 304, the telescopic oil cylinder 304 makes the telescopic rod 305 go down and push the rotating frame 111 downward, drives the docking rack 101 to go down in the first sliding groove 202, reduces the distance between the discharge port 108 and the conveyor belt 404, so that the coal can be more concentratedly dropped on the conveyor belt 404 through the discharge port 108, the docking effect is better, and the possibility of scattering of the coal in the falling process is reduced, and the relatively small drop makes the speed of the coal after the deceleration of the buffering mechanism 1 relatively low when falling on the conveyor belt, reducing the impact force on the conveyor belt 404 and prolonging the service life of the device, and when the unloading speed of the coal on the transfer machine head 401 is fast, the motor 301 can be started to drive the driving gear 302 to rotate, the driving gear 302 rotates to drive the driven gear 303 to rotate, the driven gear 303 rotates to drive the telescopic oil cylinder 304 to rotate, and the telescopic rod 305 pushes the rotating frame 111 at the bottom of the docking rack 101 away from the transfer machine head 401, so that the buffering frame 105 rotates around the rotating shaft 109, and the sliding block 110 moves out of the second sliding groove 203, so that the docking rack 101 is inclined, and the opening of the buffering frame 105 can cover the position of the guide plate 403 away from the transfer machine head 401, avoiding the situation that the coal on the docking rack flies out and scatters, reducing the loss of coal in the transfer process, and improving the effective transfer amount of coal.

[0042] The working principle is that when the coal is unloaded from the transfer machine head 401 to the docking rack 101, it will fall into the buffering frame 105 along the inclined surface of the guide plate 403, enter the buffering frame 105, and fall onto the conveyor belt 404 below through the discharge port 108 at the bottom of the buffering frame 105. In this process, the coal will generate an impact force on the buffering frame 105, causing the buffering frame 105 to drive the piston rod 104 to go down, compressing the spring 103 and the space inside the cavity 102, and increasing the air pressure inside the cavity 102. The gas will enter the air bag 107 through the air hole 106, causing the air bag to gradually fill, absorbing the impact force through the air pressure in the cavity 102 and the elastic force of the spring 103, and buffering the movement of the buffering frame 105. When the impact force on the buffering frame 105 is large, the air pressure in the air hole 106 will cause the top of the air bag 107 to expand to the extent of abutting against the bottom of the buffering frame 105, supporting the bottom of the buffering frame 105 and further buffering the buffering frame 105;

[0043] When the height of the roadway is high, the telescopic oil cylinder 304 can be used to make the telescopic rod 305 go down and push the rotating frame 111 downward, drive the receiving frame 101 to go down inside the first sliding groove 202 through the rotating shaft 109, reduce the distance between the discharge port 108 and the conveying belt 404, and make the coal fall more densely on the conveying belt 404 through the discharge port 108;

[0044] When the unloading speed of the coal on the transfer machine head 401 is fast, the motor 301 can be started to make the driving gear 302 rotate, the driving gear 302 rotates to drive the driven gear 303 to rotate, the driven gear 303 rotates to drive the telescopic oil cylinder 304 to rotate, and the telescopic rod 305 pushes the rotating frame 111 at the bottom of the receiving frame 101 away from the transfer machine head 401, so that the buffer frame 105 rotates around the rotating shaft 109, the sliding block 110 moves out of the second sliding groove 203, the receiving frame 101 is inclined, and the opening of the buffer frame 105 can cover the position of the guide plate 403 away from the transfer machine head 401, so as to receive the coal with high speed.
