[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-3 The utility model provides a mining screen, comprising a U-shaped fixed plate 1, and further comprising:

[0025] A U-shaped mounting base 2 is fixed to one side of the top surface of the U-shaped fixing plate 1. The inner side of the U-shaped mounting base 2 is rotatably connected to a U-shaped mounting plate 3. A U-shaped slot is provided on the inner side of the U-shaped mounting plate 3. A screen 4 is inserted into the inner wall of the U-shaped slot of the U-shaped mounting plate 3.

[0026] There are two rotating shafts 11 and they are symmetrically distributed and fixed on both sides of the U-shaped mounting plate 3. The outer surfaces of the two rotating shafts 11 are respectively rotatably sleeved with support rods 7. Rectangular grooves 6 are provided on both sides of the top surface of the U-shaped fixing plate 1. The bottom ends of the support rods 7 abut against the inner walls of the rectangular grooves 6. Fixed seats 12 are fixed on the top surfaces of the screen 4 on both sides of the U-shaped mounting plate 3. A mounting groove is provided on the surface of the fixing seat 12. An abutment mechanism that cooperates with the screen 4 is provided inside the mounting grooves of the two fixing seats 12.

[0027] It is worth noting that by opening the support rod 7 and inserting its end into the rectangular groove 6, the support rod 7 is limited so that the support rod 7 supports the screen 4. When the screen 4 is not in use, the support rod 7 is rotated and stored, thereby facilitating the folding of the screen 4 and the U-shaped fixing plate 1 and reducing space occupancy.

[0028] Further as Figure 1 and Figure 3 As shown, it is worth mentioning that the abutment mechanism includes:

[0029] A fixing rod 13 is fixed to the inner wall of the mounting groove, a sliding seat 15 is slidingly sleeved on the outer surface of the fixing rod 13, a spring 14 is sleeved on the outer surface of the fixing rod 13, one end of the spring 14 is fixed to the inner wall of the mounting groove, and the other end of the spring 14 is fixed to the surface of the sliding seat 15, one side of the sliding seat 15 is rotatably connected to a connecting rod 10, and a stop block 9 that cooperates with the top surface of the screen 4 is fixed to the end of the connecting rod 10;

[0030] The grip ring 22 is fixed to one side of the connecting rod 10 .

[0031] Further as Figure 2 As shown, it is worth mentioning that two support rollers 19 are rotatably installed on the inner side of the U-shaped mounting plate 3, and the outer surfaces of the two support rollers 19 are in contact with the surface of the screen 4. The support rollers 19 can support the screen 4 on the one hand and facilitate the movement of the screen 4 on the other hand.

[0032] Further as Figure 2 As shown, it is worth mentioning that two limiting chutes 18 are provided on the inner side of the U-shaped fixed plate 1, and a collecting frame 8 is provided on the inner side of the U-shaped fixed plate 1 corresponding to the screen 4. The limiting bars 17 are fixed on both sides of the collecting frame 8, and the limiting bars 17 are slidably connected with the limiting chutes 18. The screened ore is collected through the collecting frame 8, and the collecting frame 8 is stuck in the limiting chute 18 of the U-shaped fixed plate 1 through the limiting bars 17, thereby limiting the collecting frame 8.

[0033] Further as Figure 1 and Figure 2As shown, it is worth mentioning that two first wheels 5 are rotatably installed on both sides of the U-shaped fixed plate 1, and the first wheels 5 facilitate the movement of the screen 4; four second wheels 16 distributed in a rectangular shape are fixedly installed on the bottom surface of the collecting frame 8, and the second wheels 16 facilitate the movement of the collecting frame 8 and the operation of the staff; connecting plates 21 are fixed on both sides of the U-shaped fixed plate 1, and the top surface of the connecting plate 21 is movably penetrated by fixed piles 20. When the screen 4 is performing screening work, the fixed piles 20 are inserted into the ground to limit the U-shaped fixed plate 1, thereby maintaining the stability of the screen 4 during the screening process.

[0034] This scheme has the following working process: by shoveling the crushed ore toward the screen 4, the crushed ore is screened through the screen 4, and the screened ore falls into the collecting frame 8 for collection. The screen 4 is supported by the support rod 7. The screen 4 is prone to wear after long-term use. The screening efficiency of the damaged screen 4 is reduced, so the connecting rod 10 is pulled up by the grip ring 22, so that the connecting rod 10 drives the sliding seat 15 to slide on the fixed rod 13, thereby driving the block 9 to disengage from the top surface of the screen 4, releasing the limit on the screen 4, and rotating the connecting rod 10 at the same time, so as to remove the screen 4 from the U-shaped slot, and then replace the damaged screen 4. After replacing the new screen 4, the sliding seat 15 moves down and resets under the elastic force of the spring 14, and the staff rotates the connecting rod 10 so that the block 9 is stuck on the top surface of the screen 4, thereby limiting the screen 4, and completing the installation of the screen 4.

[0035] According to the above working process, it can be known that: the ore is screened by the screen 4, and the function of convenient disassembly and assembly of the screen 4 is realized through the cooperation of the abutment mechanism and the screen 4, thereby greatly improving the convenience of the staff during actual operation, and thus maintaining the screening efficiency. By opening the support rod 7 and inserting its end into the rectangular groove 6, the support rod 7 is limited so that the support rod 7 supports the screen 4. When the screen 4 is not in use, the support rod 7 is rotated and stored, thereby facilitating the folding of the screen 4 and the U-shaped fixing plate 1 and reducing space occupancy.

[0036] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.

[0037] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
