[0022] The height adjustment device 2 includes a threaded rod 12, a fixed disc 13, an adjustment hole 14 and an adjustment rod 15. The middle of the top end of the fixed disc 13 is fixedly connected to the bottom end of the threaded rod 12. The adjustment hole 14 is opened through the end of the threaded rod 12 away from the thread, and the adjustment rod 15 is slidably inserted into the inside of the adjustment hole 14.

[0023] Four threaded rods 12 are evenly arranged below the bottom support legs of the support frame 3, and the threaded ends of the threaded rods 12 are threadedly connected to the inside of the bottom support legs of the support frame 3. The distance between the fixed disc 13 and the bottom support legs of the support frame 3 is adjusted by rotating the threaded rods 12 to achieve the lifting and lowering of the fixed disc 13.

[0024] The driving end of the motor 10 is fixedly connected to one end of the screw feeding rod 11 close to the motor 10 , and the screw feeding rod 11 is driven to rotate by the driving end of the motor 10 .

[0025] The fixing disc 13 is evenly penetrated with fixing holes, through which the buffer silo device 1 is fixed to prevent shaking during operation and displacement of the discharge chute 5 , and the fixing disc 13 is fixed to prevent the threaded rod 12 from rotating.

[0026] There is one adjusting rod 15 , and the adjusting rod 15 is slidably plugged with the four threaded rods 12 through the adjusting holes 14 , so that the adjusting rod 15 is convenient for adjusting the rotation of the threaded rods 12 .

[0027] The spiral feeding rod 11 is provided with spiral blades, and the rotation of the spiral feeding rod 11 drives the spiral blades to rotate, thereby pushing the coal from the bottom end of the buffer silo 4 to the discharge chute 5 .

[0028] Working principle: During use, the adjusting rod 15 is inserted into the adjusting hole 14 by external force, and then the adjusting rod 15 is rotated by external force. The rotation of the adjusting rod 15 drives the threaded rod 12 to rotate. Since the threaded rod 12 and the legs at the bottom end of the support frame 3 are threadedly connected, the rotating threaded rod 12 moves upward, and the movement of the threaded rod 12 drives the fixed disc 13 to move upward until the bottom end of the fixed disc 13 is away from the bottom surface, thereby realizing the lifting of the threaded rod 12, and then the remaining three threaded rods 12 are lifted in turn. At this time, the bottom ends of the four fixed discs 13 are away from the bottom surface, and the bottom surface of the fixed disc 13 is located above the bottom ends of the wheels 7 and the universal wheels 9, so that the bottom ends of the wheels 7 and the universal wheels 9 are in contact with the ground, and then the support frame 3 is pushed by external force to move, and the direction can be changed by the universal wheels 9. When it moves to the desired position, the direction is adjusted so that the discharge port of the discharge chute 5 is located at the conveyor belt for transporting coal. The adjusting rod 15 is inserted into the adjusting hole 14 by external force, and the adjusting rod 15 is rotated in the opposite direction by external force, so that the threaded rod 12 moves downward, and the movement of the threaded rod 12 drives the fixed disc 13 to move downward until the bottom end of the fixed disc 13 is close to the ground, and then all the threaded rods 12 are adjusted in turn so that the bottom ends of all the fixed discs 13 are close to the ground, and then the threaded rod 12 is rotated again by adjusting the rod 15 until the bottom ends of the wheels 7 and the universal wheels 9 leave the ground, and then the fixed disc 13 is fixed by bolts through the fixing holes on the fixed disc 13 to complete the transfer work, and then the motor 10 is started and the coal is poured into the buffer bin 4, and the rotation of the motor 10 drives the spiral feeding rod 11 to rotate, and the rotation of the spiral feeding rod 11 drives the spiral blades to rotate, thereby pushing the coal at the bottom end of the buffer bin 4 to the discharge chute 5, and the coal falls onto the coal conveyor belt through the discharge chute 5.
