[0018] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, the storage structure includes two first L-shaped seats 10 fixedly installed on the top of the first storage housing 5. A first cylinder 11 is fixedly installed on the top of the first L-shaped seat 10. The output end of the first cylinder 11 is installed with the top of the U-shaped frame 14. A plurality of first support plates 15 are provided on the inner wall of the U-shaped frame 14. A first stop bar 16 is provided on the top of the first support plate 15. A second stop bar 17 is provided on the side wall of the first stop bar 16. A limiting groove is formed between the first stop bar 16, the second stop bar 17 and the first support plate 15. A pushing structure is provided on the outer wall of the first storage housing 5. The pushing structure pushes the screening mesh frame 32 located in the limiting groove to move. The pushing structure includes a second L-shaped seat 12 fixedly installed on the outer wall of the first storage housing 5. One end of the second L-shaped seat 12 is fixedly installed with a second cylinder 13. The output end of the second cylinder 13 is connected to the push rod 18 inside the first storage housing 5. When the first cylinder 11 on the second storage housing 5 works, it drives the U-shaped frame 14 to move downward to adjust the corresponding screening mesh frame 32 to be replaced to a suitable position. Then, when the second cylinder 13 works, the push rod 18 will move accordingly to push the corresponding screening mesh frame 32 to move, so that the screening mesh frame 32 is inserted into the corresponding positioning card slot 41 at the first limiting block 35 and the second limiting block 36, completing the replacement of the screening mesh frame 32. The operation is simple and the efficiency is high.

[0019] Refer to Figure 1 , Figure 5 and Figure 6, the pulling structure includes a second servo motor 24 installed on the outer wall of the second storage housing 4.

A plurality of water spray heads are provided at the bottom of the water spray pipe 22. A second support plate 23 is provided on the inner wall of the second storage housing 4. When replacing the screening mesh frame 32, the hydraulic cylinder 39 works, so that one end of the screening mesh frame 32 is placed on the support projection 40, and the screening mesh frame 32 is in a horizontal state. The second servo motor 24 in the pulling structure works to drive the second lead screw 25 to rotate. While the second lead screw 25 rotates, the second lead screw sleeve block 26 is moved to a suitable position. At the same time, the third cylinder 29 on the support block 27 works to drive the limit projection 28 to move upward, and the limit projection 28 will be inserted into the corresponding positioning hole opened on the positioning block 34. The second servo motor 24 works again to drive the second lead screw 25 to rotate again, so that the second lead screw sleeve block 26 moves in the other direction, and the screening mesh frame 32 embedded in the first limit block 35 and the second limit block 36 can be slowly removed, and finally the screening mesh frame 32 is moved to the second support plate 23 on the inner wall of the first storage housing 4.

[0020] Refer to Figure 1 , Figure 7 and Figure 8, the screening mechanism includes fixing bars 38 arranged on the inner wall of the screening box 30. Two support seats are fixedly installed on the fixing bars 38, and the support seats are rotatably installed with the hydraulic cylinder 39. The output end of the hydraulic cylinder 39 is installed with the connecting block 37. One end of the connecting block 37 is fixedly installed at one end of the second limit block 36. A positioning slot 41 for installing one end of the screening mesh frame 32 is opened at one end of the second limit block 36. The other end of the screening mesh frame 32 is installed in the positioning slot 41 opened on the first limit block 35. Both ends of the first limit block 35 are rotatably installed on the inner wall of the screening box 30. Support bumps 40 are also arranged on the inner wall of the screening box 30, and the support bumps 40 position and support the second limit block 36. A positioning block 34 is arranged on one side of the screening mesh frame 32, and a positioning hole is opened on the positioning block 34. An aggregate box 31 is placed below the screening mesh frame 32. Under the action of the hydraulic cylinder 39, the screening mesh frame 32 is in an inclined state to screen the lithium ore material.

[0021] Refer to Figure 1 and Figure 2 , the driving mechanism includes a driving motor 6 fixedly installed on the top of the support base 1. The output end of the driving motor 6 is connected to one end of the driving shaft 7. Two driving gears 8 are fixedly installed on the driving shaft 7, and the driving gears 8 are engaged with the corresponding driven gears 9 installed on the grinding housing 2.

[0022] The implementation principle of a mineral grinding device for lithium ore processing in an embodiment of the present invention is as follows: The lithium ore material to be ground enters the grinding housing 2 through the feed port on the grinding housing 2. Combining with the drive mechanism, the grinding housing 2 is driven to rotate. The steel balls in the grinding housing 2 grind the lithium ore material. The ground material comes out through the discharge pipe 3 and enters the screening mesh frame 32 in the screening mechanism. Under the action of the hydraulic cylinder 39, the screening mesh frame 32 is in an inclined state to screen the lithium ore material. When the screening mesh frame 32 needs to be replaced, the hydraulic cylinder 39 works, making one end of the screening mesh frame 32 rest on the support convex block 40, and the screening mesh frame 32 is in a horizontal state. The second servo motor 24 in the pulling structure works to drive the second lead screw 25 to rotate. While the second lead screw 25 rotates, the second lead screw block 26 is moved to a suitable position. Then, the third cylinder 29 on the support block 27 works to drive the limit convex head 28 to move upward, and the limit convex head 28 will insert into the corresponding positioning hole opened on the positioning block 34. The second servo motor 24 works again to drive the second lead screw 25 to rotate again, making the second lead screw block 26 move in the other direction, and the screening mesh frame 32 embedded in the first limit block 35 and the second limit block 36 can be slowly removed. Finally, the screening mesh frame 32 is moved to the second support plate 23 on the inner wall of the first storage housing 4. The first cylinder 11 on the second storage housing 5 works to drive the U-shaped frame 14 to move downward, adjusting the corresponding screening mesh frame 32 to a suitable position. Then, the second cylinder 13 works, and the push rod 18 will move accordingly, pushing the corresponding screening mesh frame 32 to move, so that the screening mesh frame 32 is inserted into the corresponding positioning card slot 41 at the first limit block 35 and the second limit block 36, completing the replacement of the screening mesh frame 32. The operation is simple and efficient. Moreover, the screening mesh frame 32 replaced on the second storage housing 4 can be cleaned. Tap water can be sprayed out through the spray heads on the spray pipe 22. And the first servo motor 19 works to drive the first lead screw 20 to rotate. While the first lead screw 20 rotates, the first lead screw block 21 will move accordingly, making the spray pipe 22 move back and forth to clean the screening mesh frame 32.

[0023] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
