Abstract
Description
Technical Field
[0001] This utility model relates to the field of mineral processing technology, and in particular to a mineral processing device with a buffer function. Background Technology
[0002] Ore screening equipment is a mechanical device used for sorting, classifying or purifying ores. It is designed to separate useful minerals from waste rock or ores of different grades based on the physical or chemical properties of the ore (such as particle size, density, magnetism, conductivity, color, etc.).
[0003] Existing mineral processing equipment is not designed with the adjustability of the material drop point in mind, which causes the ore to always impact the same fixed position on the screen plate during the screening process. This continuous local impact not only accelerates the wear and deformation of the screen plate, but also shortens its service life and increases equipment maintenance costs. In addition, frequent replacement of screen plates will affect production efficiency and even lead to downtime for maintenance, further affecting the continuity and stability of mineral processing operations.
[0004] Therefore, in response to the problem that the material drop point of the existing mineral processing equipment cannot be adjusted during use, resulting in the falling ore impacting the fixed point of the screen plate for a long time and causing the screen plate to be easily damaged, a mineral processing device with a buffer function can be designed. Utility Model Content
[0005] To overcome the problem that the material drop point of existing mineral processing equipment cannot be adjusted during use, resulting in the falling ore impacting the fixed point of the screen plate for a long time, which easily damages the screen plate.
[0006] The technical solution of this utility model is as follows: a mineral processing device with buffer function, including support legs; it also includes a lead screw and a corrugated pipe. The support legs are arranged in a rectangular array of four, and each of the four support legs is equipped with a buffer component. The bottom of the four buffer components is connected to a screen, and a feed hopper is arranged between the four buffer components. An installation frame is connected to the bottom left side of the feed hopper. A first drive motor is installed on the front side of the installation frame. The lead screw is rotatably connected to the front and rear ends of the inner side of the installation frame. The first drive motor is used to drive the lead screw to rotate. A movable seat is threaded through the circumference of the lead screw. A first support arm is connected to the right side of the movable seat. A fixing ring is connected to the right end of the first support arm. A corrugated pipe is fixed inside the fixing ring. The top of the corrugated pipe is connected to the bottom outlet of the feed hopper.
[0007] Preferably, by setting a first drive motor, its output end will drive the lead screw to rotate during operation. When the lead screw rotates, it can drive the movable seat that is threaded with it to move back and forth. When the movable seat moves, it causes the first support arm to drive the fixed ring to move synchronously, thereby pulling the corrugated pipe to move back and forth. This adjusts the discharge point of the corrugated pipe, thereby avoiding the problem that the ore will hit the screen at a single position for a long time during the drop, which will easily damage the screen. This solves the problem that the discharge point of the existing mineral processing equipment cannot be adjusted during use, which causes the falling ore to impact the fixed point of the screen plate for a long time, making the screen plate easy to be damaged.
[0008] Preferably, the buffer assembly includes a lifting frame, a first hook, a sliding plate, a connecting rod, a spring, and a fixing plate; each of the four legs is equipped with a lifting frame, the inner side of the lifting frame is hooked to the first hook, the outer side of the first hook is slidably connected to the sliding plate, the left and right sides of the sliding plate are connected to the connecting rod, the bottom of the sliding plate is connected to the spring, and the bottom of the spring is equipped with a fixing plate.
[0009] Preferably, the buffer assembly also includes a second hook; two second hooks are installed on both the front and rear sides of the screen, and the second hooks are connected to the corresponding connecting rods.
[0010] Preferably, a limiting frame is provided on the bottom right side of the feed hopper. The front and rear ends of the limiting frame are connected to limiting rods. The outer surface of the limiting rods is slidably connected to a limiting block. A second support arm is installed on the left side of the limiting block, and the left end of the second support arm is connected to a fixing ring.
[0011] Preferably, two bearing seats are installed on both the front and rear sides of the feed hopper, and a rotating shaft is connected between the two corresponding bearing seats. A crushing roller is installed on the outer side of the rotating shaft.
[0012] Preferably, a first drive wheel is provided at the front end of the left rotating shaft and the rear end of the right rotating shaft. Two second drive motors are installed on the top left side of the feed hopper frame. A second drive wheel is installed at the output end of each of the two second drive motors. The second drive motors drive the corresponding second drive wheel to rotate. A belt is fitted on the outer side of the corresponding first drive wheel and second drive wheel.
[0013] Preferably, a fixed base is installed at the bottom of the screen, and a vibration motor is installed on the left side of the fixed base to drive the screen to vibrate.
[0014] The beneficial effects of this utility model are:
[0015] By setting a fixed ring that can move back and forth, the corrugated pipe moves synchronously, thereby precisely controlling the distribution range of the ore drop point on the screen. This design makes the impact position of the drop material dynamically change on the screen surface, effectively avoiding local fatigue damage caused by long-term concentrated impact of ore on the same area. This uniformly distributed impact method significantly reduces the wear rate of the screen, extends the service life of the screen, and maintains stable screening efficiency.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-5This utility model provides an embodiment of a mineral processing device with a buffer function, including support legs 1; it also includes a lead screw 7 and a bellows 23. Four support legs 1 are arranged in a rectangular array, each with a buffer assembly. A screen 3 is connected to the bottom of each of the four buffer assemblies. A feed hopper 4 is positioned between the four buffer assemblies. A mounting frame 5 is connected to the bottom left side of the feed hopper 4. A first drive motor 6 is mounted on the front side of the mounting frame 5. The lead screw 7 is rotatably connected to the front and rear ends of the inner side of the mounting frame 5. The first drive motor 6 drives the lead screw 7 to rotate. A movable seat 8 is threaded through the circumference of the lead screw 7. A first support arm 9 is connected to the right side of the movable seat 8. A fixing ring 10 is connected to the right end of the support arm 9. A corrugated pipe 23 is fixed to the inner side of the fixing ring 10. The top of the corrugated pipe 23 is connected to the bottom discharge port of the feed hopper 4. It is driven by the first drive motor 6. During operation, its output end drives the lead screw 7 to rotate. When the lead screw 7 rotates, it pushes the moving seat 8 to move axially through the threaded engagement with the moving seat 8. The moving seat 8 is rigidly connected to the first support arm 9, which in turn drives the fixing ring 10 to move synchronously, so that the corrugated pipe 23 installed on the fixing ring 10 can move back and forth, thereby adjusting the discharge point of the corrugated pipe 23. This structure can avoid the ore from impacting the same position of the screen 3 for a long time, effectively reducing the risk of local wear of the screen 3.
[0024] Please see Figures 1-5In this embodiment, the buffer assembly includes a lifting frame 201, a first hook 202, a sliding piece 203, a connecting rod 204, a spring 205, and a fixing piece 206. Each of the four support legs 1 is equipped with a lifting frame 201. The first hook 202 is hooked to the inner side of the lifting frame 201, and the sliding piece 203 is slidably connected to the outer side of the first hook 202. The left and right sides of the sliding piece 203 are connected to the connecting rod 204, and the bottom of the sliding piece 203 is connected to the spring 205. The bottom of the spring 205 is equipped with the fixing piece 206. By setting the first hook 202, it can be connected to the lifting frame 201. When the connecting rod 204 is pulled, it will drive the sliding piece 203 to move synchronously downwards along the outer surface of the first hook 202. The sliding piece 203 compresses the spring 205, forcing the spring 205 to contract. Then, the rebound force of the spring 205 will drive the connecting rod 204 and the sliding piece 203 to return to their original positions, thereby achieving the buffering function. Yes, the buffer assembly also includes a second hook 207; two second hooks 207 are installed on both the front and rear sides of the screen 3. The second hooks 207 are hooked to the corresponding connecting rods 204. By setting the second hooks 207, it is easy to connect the screen 3 to the connecting rods 204, which improves the ease of installation. A limit frame 11 is set on the bottom right side of the feed hopper 4. The front and rear ends of the limit frame 11 are connected to limit rods 12. The outer surface of the limit rods 12 is slidably connected to a limit block 13. A second support arm 24 is installed on the left side of the limit block 13. The left end of the second support arm 24 is connected to the fixed ring 10. By setting the limit rods 12 and the limit block 13, when the fixed ring 10 moves, the second support arm 24 drives the limit block 13 to slide along the surface of the limit rod 12. The limit rod 12 can limit the sliding direction of the limit block 13, thereby improving the stability of the movement of the fixed ring 10.
[0025] Please see Figure 2 and Figure 4In this embodiment, two bearing seats 14 are installed on both the front and rear sides of the feed hopper 4. A rotating shaft 15 is connected between the two corresponding bearing seats 14. A crushing roller 16 is arranged on the outer side of the rotating shaft 15. By setting the bearing seats 14 and the rotating shaft 15, the crushing roller 16 can rotate. When the two crushing rollers 16 rotate in opposite directions, they can crush the ore, thereby improving the screening efficiency. The front end of the left rotating shaft 15 and the rear end of the right rotating shaft 15 are both provided with first transmission wheels 17. Two second drive motors 18 are installed on the top left side of the frame of the feed hopper 4. The output ends of the two second drive motors 18 are both equipped with second transmission wheels 19. Motor 18 drives the corresponding second transmission wheel 19 to rotate. Belt 20 is fitted around the outer sides of the corresponding first transmission wheel 17 and second transmission wheel 19. By setting the second drive motor 18, the second transmission wheel 19 can be driven to rotate during operation. When the second transmission wheel 19 rotates, it can drive the first transmission wheel 17 to rotate through the linkage of the belt 20, thereby driving the crushing roller 16 to rotate. A fixed seat 21 is installed at the bottom of the screen 3. A vibration motor 22 is set on the left side of the fixed seat 21. The vibration motor 22 is used to drive the screen 3 to vibrate. By setting the vibration motor 22, the screen 3 can be driven to vibrate at high frequency during operation, thereby screening the ore.
[0026] During operation, the first drive motor 6 starts, and its output drives the lead screw 7 to rotate. Through its threaded engagement with the movable seat 8, the lead screw 7 moves back and forth. The fixed ring 10 is linked to the movable seat 8 via the first support arm 9, thereby precisely pulling the bellows 23 to adjust the discharge point. During this process, the limiting block 13 moves synchronously with the fixed ring 10 via the second support arm 24 and slides along the surface of the limiting rod 12. The constraint of the limiting rod 12 on the sliding direction significantly improves the movement stability of the fixed ring 10. In the hoisting stage, the first hook 202 is connected to the hoisting frame 201. When the connecting rod 204 is subjected to… When pulled by an external force, the sliding plate 203 moves down along the hook and compresses the spring 205. The spring 205's rebound force provides a buffering function. The second hook 207 is used to quickly connect the screen 3 and the connecting rod 204, simplifying the installation process. The crushing stage is performed by two sets of relatively rotating crushing rollers 16. The crushing rollers 16, supported by the bearing seat 14 and the rotating shaft 15, work under the drive of the second drive motor 18. The second transmission wheel 19 is linked to the first transmission wheel 17 through the belt 20, driving the crushing rollers 16 to efficiently crush the ore. Finally, the vibration motor 22 drives the screen 3 to vibrate at high frequency, completing the ore screening operation.
[0027] Through the above steps, after the first drive motor 6 starts, its output shaft drives the lead screw 7 to rotate. Since the moving seat 8 and the lead screw 7 are threaded together, the rotation of the lead screw 7 will push the moving seat 8 to move linearly along the axial direction. The moving seat 8 is fixedly connected to the first support arm 9, and the first support arm 9 drives the fixed ring 10 to move synchronously, thereby enabling the corrugated pipe 23 installed on the fixed ring 10 to move back and forth. Through this adjustment method, the discharge point of the corrugated pipe 23 can be dynamically adjusted, avoiding the continuous impact of ore on the fixed area of the screen 3, extending the service life of the screen 3, thus solving the problem that the discharge point of the existing mineral processing equipment cannot be adjusted during use, resulting in the falling ore impacting the fixed point of the screen plate for a long time, which easily damages the screen plate.
