The push column can then drive the closing plate to move and close the port of the second discharge pipe. The push column can be bounced back by a spring, so that the closing plate can move continuously left and right, making it convenient to close the discharge port of the second discharge pipe at any time for buffering.

[0023] A first discharge pipe 11 is provided on the lower side of the discharge port 10, and a second discharge pipe 12 is provided on the outer side of the first discharge pipe 11. A first slider 13 is provided at the connection between the first discharge pipe 11 and the second discharge pipe 12. A first slide rail 14 is provided on the outer side of the first slider 13. A support frame 15 is fixed on the lower surface of the discharge bin 9. A second bearing 16 is provided at the bottom end of the support frame 15. A threaded column 17 is provided on the inner side of the second bearing 16. A hand crank 18 is fixed at the bottom end of the threaded column 17. A threaded groove 19 is threadedly connected to the outer periphery of the threaded column 17. A lifting plate 20 is provided on the outer side of the threaded groove 19. A first limiting groove 21 is provided on the outer side wall of the lifting plate 20. When the first motor 3 is turned on, the first rotating shaft 4 and the rotating conveyor plate 5 can be driven to rotate. The rotating conveyor plate 5 can then transport the material inside the discharge bin 7 to the inside of the discharge bin 9.
[0024] The feeding hopper 9 and the support frame 15 form a fixed structure, and the support frame 15 forms a rotating structure with the threaded column 17 through the second bearing 16, and the threaded column 17 forms a threaded connection with the lifting plate 20 through the threaded groove 19.
[0025] The lifting plate 20 and the second discharge pipe 12 form a fixed structure, and the second discharge pipe 12 forms a sliding structure with the first discharge pipe 11 through the first slider 13 and the first slide rail 14. The first discharge pipe 11 and the discharge bin 9 form a fixed structure. By turning the hand handle 18 by external force, the threaded column 17 can be driven to rotate. Through the threaded connection between the threaded column 17 and the threaded groove 19, the rotation of the threaded column 17 can make the lifting plate 20 rise and fall. The rise and fall of the lifting plate 20 can drive the second discharge pipe 12 to rise and fall, thereby facilitating the downward adjustment of the position of the discharge port.
[0026] Example 2
[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment further illustrates Example 1. A support plate 22 is fixed to the side wall of the second discharge pipe 12. A second motor 23 is fixed to the side wall of the support plate 22. A second rotating shaft 24 is provided at the rotating end of the second motor 23. An inclined rotating drum 25 is fixed to the other end of the second rotating shaft 24. A ball bearing slide rail 26 is provided at the end of the inclined rotating drum 25. A rolling ball 27 is provided on the inner side of the ball bearing slide rail 26. A pushing column 28 is provided on one side of the rolling ball 27.

A spring 32 is provided on one side of the fixing plate 30. A connecting plate 33 is provided at the other end of the pushing column 28. A closing plate 34 is fixed to the bottom end of the connecting plate 33.
[0028] The inclined rotating drum 25 and the second rotating shaft 24 form a rotating structure through the rotation of the second motor 23. The inclined rotating drum 25 forms a sliding structure through the ball slide rail 26 and the rolling ball 27. The rolling ball 27 forms an engaging structure with the push column 28. When the second motor 23 is turned on, the second rotating shaft 24 and the inclined rotating drum 25 can be driven to rotate. The rotation of the inclined rotating drum 25 can intermittently squeeze the push column 28 downward through the ball slide rail 26 and the rolling ball 27.
[0029] The push column 28 and the fixed plate 30 form a fixed structure, and the fixed plate 30 forms an elastic structure with the support plate 22 through the spring 32. The push column 28 forms a sliding structure with the support plate 22 through the second limiting groove 29. The push column 28 forms a fixed structure with the closing plate 34 through the connecting plate 33. The push column 28 can drive the closing plate 34 to move and close the port of the second discharge pipe 12. The spring 32 can push the push column 28 back, so that the closing plate 34 can move continuously left and right, so that the discharge port of the second discharge pipe 12 can be closed at any time for buffering.
[0030] Working principle: First, the operator needs to put the material into the discharge hopper 7. Then, by turning on the first motor 3, the first rotating shaft 4 and the rotating conveyor plate 5 can be driven to rotate. The rotating conveyor plate 5 can then transport the material inside the discharge hopper 7 to the discharge hopper 9. Then, by turning the hand handle 18 by external force, the threaded column 17 can be driven to rotate. Through the threaded connection between the threaded column 17 and the threaded groove 19, the rotation of the threaded column 17 can cause the lifting plate 20 to rise and fall. The rising and falling of the lifting plate 20 can drive the second discharge pipe 12 to rise and fall, thus facilitating downward adjustment. The discharge port is located at the second motor 23, which drives the second rotating shaft 24 and the inclined rotating drum 25 to rotate. The rotation of the inclined rotating drum 25 intermittently presses the pushing column 28 downward through the ball slide rail 26 and the rolling ball 27. The pushing column 28 can then drive the closing plate 34 to move and close the port of the second discharge pipe 12. The spring 32 can bounce the pushing column 28 back, so that the closing plate 34 can move continuously left and right, so that the discharge port of the second discharge pipe 12 can be closed at any time for buffering.
