[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1-9 As shown, a mineral grading device includes: a mineral grading box 1, three collection boxes 101 arranged on one side of the mineral grading box 1, each of the three collection boxes 101 having a material transfer port 105 on one side, a conveyor belt 102 arranged inside the material transfer port 105, three filter plates 103 arranged inside the mineral grading box 1, an impact box 104 arranged on one side of the mineral grading box 1, a vibration component arranged inside the mineral grading box 1 for screening the mineral on the filter plates 103, the vibration component including: a lifting rod 204, an impact column 402 and a connecting rod 403, and a collection component arranged inside the mineral grading box 1 for collecting the mineral on the filter plates 103, the collection component including: a moving plate 603, collection boxes 101 and conveyor belt 102.

[0026] The vibrating assembly utilizes the lifting rod 204, impact column 402, and connecting rod 403 to screen the ore on the filter plate 103 according to the holes on the filter plate 103, thereby achieving more accurate ore grading. Secondly, through the moving plate 603, collection box 101, and conveyor belt 102 in the collection assembly, the screened ore can be quickly pushed to the collection box 101 and then rolled onto the conveyor belt 102, avoiding stagnation and delay in the intermediate links, thereby improving the overall screening and conveying efficiency.

[0027] The impact chamber 104 is equipped with a motor a2 at its top, and a rotating column 201 is driven and connected to the bottom of the motor a2. The rotating column 201 has a threaded groove 202 inside, and a threaded rod 203 is installed inside the threaded groove 202. The surface of the threaded rod 203 is threadedly connected to the inner wall of the threaded groove 202. One end of the threaded rod 203 is connected to a lifting rod 204. Multiple rocker arms 205 are installed on the outside of the lifting rod 204. A fixing rod 3 is installed inside the impact chamber 104, and a sliding sleeve 301 is installed on the outside of the fixing rod 3. A limit rod 302 is connected to one side of the lifting rod 204, and one end of the limit rod 302 is connected to the sliding sleeve 305. The moving sleeve 301 is connected to the inner wall of the mineral grading box 1, which has three pry holes 404. Each of the three pry holes 404 has a pin, and a connecting rod 403 is provided on the outside of the pin. One end of the connecting rod 403 has a movable groove b, and a rotating shaft is provided inside the movable groove b. Each of the three filter plates 103 has a limit post 4 at the bottom. The limit post 4 has an impact groove 401 inside, and an impact post 402 is provided inside the impact groove 401. The bottom of the impact post 402 is rotatably connected to one end of the connecting rod 403 through a rotating shaft. The other end of the connecting rod 403 extends through the pry hole 404 to the space between the two corresponding pry bars 205.

[0028] Because the ore entering the equipment is of varying sizes, it easily accumulates on the screen surface during ore grading, causing blockages and reducing the effective screening area and screening efficiency. The rotating column 201 is driven to rotate by motor a2, and the threaded engagement between the threaded rod 203 and the threaded groove 202 allows the threaded rod 203 to move up and down, which in turn drives the lifting rod 204 to move up and down. The lifting rod 204's movement causes the rocker arm 205 to move up and down. Since one end of each connecting rod 403 is located between two rocker arms 205, when the rocker arm 205 moves upward, the pin inside the pry hole 404 causes the connecting rod to move upward. When the other end of rod 403 moves downward, and the rocker arm 205 moves downward, the connecting rod 403 moves upward. As the connecting rod 403 moves up and down under the influence of the rocker arm 205, the impact column 402 also moves up and down. After being limited by the limiting column 4, it will accurately impact the bottom of the filter plate 103. The impact on the bottom of the filter plate 103 causes the filter plate 103 to vibrate, which in turn causes the ore to jump, roll and move on the screen surface, so that the ore is evenly dispersed on the filter plate 103. This allows fine ore particles to pass through the screen holes of the filter plate 103, while larger particles remain on the filter plate, improving the accuracy of material classification.

[0029] Each of the three filter plates 103 has a fixing block 5 at its bottom. The fixing block 5 has a force groove 501 inside. The force groove 501 has a spring 502 inside. The bottom of the spring 502 is connected to a force rod 503. The bottom of the force rod 503 is connected to a fixing plate 504. The fixing plate 504 is connected to the inner wall of the mineral grading box 1.

[0030] When the filter plate 103 vibrates, in order to ensure the vibration amplitude of the filter plate 103 and to ensure that the filter plate 103 will not shift or be damaged due to vibration, the filter plate 103 will drive the fixed block 5 to vibrate. Since the force groove 501 is equipped with a spring 502, the filter plate 103 will apply pressure to the spring 502 when it vibrates. Since the spring 502 will undergo elastic deformation after being subjected to pressure, the spring 502 can absorb and release energy when subjected to pressure, so it can quickly return to its original position when the tension is removed. In addition, the bottom of the spring 502 is equipped with a force rod 503, one end of which is connected to the inner wall of the mineral grading box 1, so that the filter plate 103 can still return to its initial position after vibration.

[0031] The ore grading box 1 has three motors b6 on one side, each motor b6 is connected to a lead screw 601 on one side, and a moving block 602 is provided on the outside of the lead screw 601. The moving block 602 has a threaded hole inside, and the inner wall of the threaded hole is threaded to the surface of the lead screw 601. The inner wall of the ore grading box 1 has three collection slots 604, and each collection slot 604 has a moving plate 603 inside. The ore grading box 1 has three moving slots on one side, and one end of the moving block 602 passes through the moving slot and is connected to the moving plate 603. Each of the three collection boxes 101 has an electric telescopic rod 7 on the outside, and a sealing plate 701 is connected to one side of the electric telescopic rod 7. The top of the ore grading box 1 has a feed inlet 702, and the bottom of the ore grading box 1 has a fine material box 703.

[0032] After the ore is screened by the filter plate 103, manually transporting the screened ore to the next work area would greatly increase labor costs and reduce the continuity and stability of the operation. The screw 601 is rotated by the motor b6. Since the inner wall of the threaded hole is threaded to the surface of the screw 601, the screw rotation between the threaded hole and the screw 601 causes the moving block 602 to drive the moving plate 603 to move on the filter plate 103, thereby pushing the ore on the filter plate 103 to the collection box 101. Since there is a slope inside the collection box 101, the ore will roll along the slope to the bottom of the collection box 101, and then be transported to the next work area by the conveyor belt 102.

[0033] Working principle:

[0034] Because the ore entering the equipment is of varying sizes, it easily accumulates on the screen surface during ore grading, causing blockages and reducing the effective screening area and screening efficiency. The rotating column 201 is driven to rotate by motor a2, and the threaded engagement between the threaded rod 203 and the threaded groove 202 allows the threaded rod 203 to move up and down, which in turn drives the lifting rod 204 to move up and down. The lifting rod 204's movement causes the rocker arm 205 to move up and down. Since one end of each connecting rod 403 is located between two rocker arms 205, when the rocker arm 205 moves upward, the pin inside the pry hole 404 causes the connecting rod to move upward. When the other end of rod 403 moves downward, and the rocker arm 205 moves downward, the connecting rod 403 moves upward. As the connecting rod 403 moves up and down under the influence of the rocker arm 205, the impact column 402 also moves up and down. After being limited by the limiting column 4, it will accurately impact the bottom of the filter plate 103. The impact on the bottom of the filter plate 103 causes the filter plate 103 to vibrate, which in turn causes the ore to jump, roll and move on the screen surface, so that the ore is evenly dispersed on the filter plate 103. This allows fine ore particles to pass through the screen holes of the filter plate 103, while larger particles remain on the filter plate, improving the accuracy of material classification.

[0035] When the filter plate 103 vibrates, in order to ensure the vibration amplitude of the filter plate 103 and to ensure that the filter plate 103 will not shift or be damaged due to vibration, the filter plate 103 will drive the fixed block 5 to vibrate. Since the force groove 501 is equipped with a spring 502, the filter plate 103 will apply pressure to the spring 502 when it vibrates. Since the spring 502 will undergo elastic deformation after being subjected to pressure, the spring 502 can absorb and release energy when subjected to pressure, so it can quickly return to its original position when the tension is removed. In addition, the bottom of the spring 502 is equipped with a force rod 503, one end of which is connected to the inner wall of the mineral grading box 1, so that the filter plate 103 can still return to its initial position after vibration.

[0036] After the ore is screened by the filter plate 103, manually transporting the screened ore to the next work area would greatly increase labor costs and reduce the continuity and stability of the operation. The screw 601 is rotated by the motor b6. Since the inner wall of the threaded hole is threaded to the surface of the screw 601, the screw rotation between the threaded hole and the screw 601 causes the moving block 602 to drive the moving plate 603 to move on the filter plate 103, thereby pushing the ore on the filter plate 103 to the collection box 101. Since there is a slope inside the collection box 101, the ore will roll along the slope to the bottom of the collection box 101, and then be transported to the next work area by the conveyor belt 102.
