[0025] The closing assembly includes a second motor 15, a second rotating shaft 16, a third gear plate 17, a second bearing 18, a fourth gear plate 19, a third bearing 20, a fixed column 21, a fifth gear plate 22, a second hollow connecting column 23, a fourth bearing 24, a threaded groove 25, a threaded column 26, a closing plate 27 and a feed pipe 28. The second motor 15 is fixed on the upper surface of the top end of the outer frame 1. The rotating end of the second motor 15 is provided with the second rotating shaft 16. The other end of the second rotating shaft 16 is fixedly connected with the third gear plate 17. The second bearing 18 is installed at the connection between the second rotating shaft 16 and the outer frame 1. A fourth gear plate 19 is arranged on one side of the third gear plate 17. The third bearing 20 is arranged inside the fourth gear plate 19. The fixed column 21 is arranged inside the third bearing 20. A fifth gear plate 22 is arranged on the other side of the fourth gear plate 19. The second hollow connecting column 23 is arranged inside the fifth gear plate 22.

[0026] The first gear plate 6 and the first rotating shaft 5 form a rotating structure through the operation of the first motor 4, and the first gear plate 6 and the second gear plate 7 form a meshing structure. Moreover, the second gear plate 7 and the centrifugal screening cylinder 9 form a fixed structure through the first hollow connecting column 8. By turning on the first motor 4, the first gear plate 6 can be driven to rotate. Through the meshing structure between the first gear plate 6 and the second gear plate 7, the rotation of the first gear plate 6 can cause the second gear plate 7 to rotate, indirectly driving the centrifugal screening cylinder 9 to rotate. When the ore material enters the interior through the feed pipe 28, water can be sprayed through the water spraying end 12, and the centrifugal screening cylinder 9 can drive the ore material to rotate in the sieve frame. Due to its relatively heavy own mass, the concentrate will remain in the residue groove of the centrifugal screening cylinder 9 or at the bottom of the centrifugal screening cylinder 9, while the waste material will be discharged from the tailing outlet 14 together with the water.

[0027] The third gear plate 17 and the second rotating shaft 16 form a rotating structure through the operation of the second motor 15, and the third gear plate 17 and the fourth gear plate 19 form a meshing structure.

Through the meshing structure between the third gear plate 17 and the fourth gear plate 19, the rotation of the third gear plate 17 can cause the fourth gear plate 19 to rotate.

[0028] The fourth gear plate 19 and the fifth gear plate 22 form a meshing structure with the second hollow connecting column 23. The second hollow connecting column 23 and the outer frame 1 form a rotating structure through the fourth bearing 24. The second hollow connecting column 23 and the threaded column 26 form a threaded connection through the threaded groove 25. The threaded column 26 and the closing plate 27 form a fixed structure. Through the meshing structure of the fourth gear plate 19 and the fifth gear plate 22, the rotation of the fourth gear plate 19 can drive multiple groups of the fifth gear plates 22 to rotate, indirectly driving the second hollow connecting column 23 to rotate. Then, through the threaded connection between the threaded groove 25 and the threaded column 26, the rotation of the second hollow connecting column 23 can cause the threaded column 26 to move up and down, thereby driving the closing plate 27 to move up and down, realizing the automatic closing or opening of the outer box 3.

[0029] Embodiment 2

[0030] As Figure 1 and Figure 2 shown, this embodiment further illustrates Embodiment 1. A drainage plate 29 is provided below the tailings outlet 14. A static flow bin 30 is fixed below the drainage plate 29. An inclined recovery trough 31 is provided on the upper surface of the static flow bin 30.

[0031] Two groups of static flow bins 30 are symmetrically distributed with respect to the center line of the drainage plate 29, and the inclined recovery troughs 31 are equally spaced on the inner bottom surface of the static flow bin 30. When water and tailings are discharged from the tailings outlet 14, they will flow through the drainage plate 29 into the tops of the two symmetrically arranged static flow bins 30. Then, the water and tailings will slowly flow through the inclined recovery troughs 31 and finally flow into the bottom of the static flow bin 30. When the water is full, it will overflow from the bottom of the static flow bin 30. When the water and tailings pass through the inclined recovery troughs 31, some heavier tailings will be sedimented one by one and further recovered.

[0032] Working principle: First, the operator needs to start the first motor 4, which can drive the first gear plate 6 to rotate. The rotation of the first gear plate 6 can cause the second gear plate 7 to rotate, indirectly driving the centrifugal screening cylinder 9 to rotate. When the ore material enters the interior through the feed pipe 28, water can be sprayed through the water spraying end 12. The centrifugal screening cylinder 9 can then drive the ore material to rotate in the sieve frame. Since the concentrate is heavier in its own mass, it will remain in the residue tank of the centrifugal screening cylinder 9 or at the bottom of the centrifugal screening cylinder 9, while the waste material will be discharged together with water from the tailings outlet 14. Then, by starting the second motor 15, the third gear plate 17 can be driven to rotate. The rotation of the third gear plate 17 can cause the fourth gear plate 19 to rotate. The rotation of the fourth gear plate 19 can cause multiple groups of fifth gear plates 22 to rotate, indirectly driving the second hollow connecting column 23 to rotate. Through the threaded connection between the threaded groove 25 and the threaded column 26, the rotation of the second hollow connecting column 23 can cause the threaded column 26 to move up and down, thereby driving the closing plate 27 to move up and down, realizing the automatic closing or opening of the outer box 3.
