Description

Technical Field

[0001] This invention relates to the field of centrifugal concentrator technology, specifically a novel multifunctional centrifugal concentrator and its usage method. Background Technology

[0002] Centrifugal concentrators are devices that perform gravity separation of mineral particles in a centrifugal force field. They are one of the most efficient gravity separation devices. Centrifugal concentrators are also called centrifugal sluices. There are many types of centrifuges, but their basic structures are the same. When a centrifuge rotates at high speed, it generates a large centrifugal force, which strengthens the gravity separation process and makes fine mineral particles more effectively recovered. Its emergence has successfully solved the problem of full recovery of fine particles. Therefore, it is widely used to recover tungsten, tin, iron and other mineral slimes.

[0003] According to the patent announcement number "CN214515293U" published on the China Patent Network, entitled "A Centrifugal Concentrator for Mineral Processing," the centrifugal concentrator includes a barrel containing a rotating drum. The drum has a hollow center and small holes on its side walls. The bottom of the drum is connected to the upper end of a shaft tube, the lower end of which passes through the bottom of the barrel and connects to one end of a rotary joint. The other end of the rotary joint is connected to one end of a water supply pipe. A second drive wheel is fitted onto the portion of the shaft tube located below the barrel. One side of the second drive wheel is connected to a first drive wheel via a belt, and a motor is connected to the top of the first drive wheel. One end of a suction pipe is inserted into the rotating drum, and the other end of the suction pipe extends through the top of the barrel to the bottom, connecting to a suction pump. This centrifugal concentrator employs a structure that combines a rotating drum, suction pipe, crossbeam, hydraulic cylinder, and suction pump, allowing the heavy ore to be immediately extracted after separation from the light ore, eliminating the need for excessively long intervals and thus increasing processing efficiency.

[0004] While the aforementioned method can extract heavy ore from the bottom of the drum, the patent still has the following problems:

[0005] (1) In the above patent, when the heavy ore is sucked out from the bottom of the drum, the equipment often needs to stop feeding before processing, which makes the equipment unable to operate continuously, thereby reducing the efficiency of mineral processing.

[0006] (2) In the process of the raw materials flowing from the pipeline in the above patent, blockages can easily occur during the discharge of multiple mineral materials, thereby affecting the discharge effect. To address this issue, we provide a new type of multi-functional centrifugal concentrator and its usage method to solve the above problems. Summary of the Invention

[0016] As a further embodiment of the present invention: multiple material feeding rods are provided, and the multiple material feeding rods are distributed at equal distances around the rotating ring.

[0017] This invention also discloses a novel multi-functional centrifugal concentrator usage method, which includes the following steps:

[0018] S1. A water inlet is provided at the bottom of the drum, and a water inlet pipe is provided at the bottom of the casing. A gap is left between the drum and the bottom of the casing. The drum and the first discharge pipe are sealed with sealing rubber. When the output end of the first drive motor drives the connecting shaft to rotate the synchronous wheel, the synchronous belt drives another synchronous wheel to rotate, thereby driving the second discharge pipe to rotate the drum through the rotating sleeve. This causes the drum to generate centrifugal force that acts on the ore entering the drum, thus performing mineral processing.

[0019] S2. When heavy ore accumulates at the bottom of the drum, the second drive motor is started. The output end of the second drive motor drives the output shaft to rotate the circular sealing cover, thereby opening the discharge port of the rotating sleeve. This allows the heavy ore accumulated at the center of the bottom of the drum to be discharged to the outside through the second discharge pipe. The output end of the second drive motor drives the output shaft to rotate the circular sealing cover one revolution and then stops. Through the cooperation of the above multiple parts, the equipment can discharge the accumulated heavy ore in a timely manner during continuous operation, thereby improving the overall practicality of the device.

[0020] S3. When heavy ore accumulates at the bottom of the drum, the electric push rod can be activated intermittently. The output end of the electric push rod pulls the slide rod, causing the connecting ring to move downward. When the shrinking ring encounters resistance, the connecting ring continues to move downward to compress the shrinking spring, so that the shrinking ring can press on the heavy ore accumulated at the bottom of the drum, thereby limiting the heavy ore outside the shrinking ring and preventing other ore from entering the discharge port of the rotating sleeve during the discharge of heavy ore. When the electric push rod stops running, the second drive motor is started.

[0021] S4. While the output shaft rotates, it drives the second large spur gear to rotate, thereby driving the small spur gear to drive the rotary pusher to rotate rapidly through the connecting shaft. The rotary pusher pushes the loop frame to pull the auxiliary frame to move laterally back and forth, so that the connecting frame drives the unblocking rod to move laterally back and forth to unblock the inside of the second discharge pipe, thereby preventing the ore from blocking the inside of the second discharge pipe and ensuring the smooth discharge of the second discharge pipe.

[0022] S5. As the slide bar moves downward, the pull rope pulls the conical sealing cover upward, thereby opening the feed port at the top of the rotating sleeve. By reversing the above steps, the ore can be prevented from continuously entering the rotating sleeve.

[0023] S6. During the lateral reciprocating movement of the unblocking rod, when the unblocking block comes into contact with the ore, the unblocking block squeezes the auxiliary spring to slide relative to the unblocking sleeve, and at the same time the third drive motor is started. The output end of the third drive motor drives the unblocking sleeve to perform local reciprocating swing, thereby actively lifting or squeezing the ore accumulated in the second discharge pipe, thereby improving the unblocking effect of the unblocking rod.

[0024] S7. During the rotation of the connecting shaft, the first large spur gear is driven to rotate synchronously. The first large spur gear drives the spur gear ring to rotate, which in turn drives the multiple material-pulling rods to rotate in a circle. The multiple material-pulling rods can move the ore pressed against the bottom of the shrinking ring, so that the ore located at the bottom of the shrinking ring can be swept away during the discharge process of the rotating sleeve. As a result, the shrinking ring gradually returns to its original position under the action of the shrinking spring. This allows the shrinking ring to isolate the heavy ore in the center of the drum from the outside world, so that other ore will not be discharged together during the discharge of heavy ore. This allows the equipment to discharge the accumulated heavy ore in a timely manner during continuous operation.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. By setting up a circular sealing cover and other parts, when heavy ore accumulates at the bottom of the drum, the second drive motor is started. The output shaft of the second drive motor drives the circular sealing cover to rotate, thereby opening the discharge port of the rotating sleeve. This allows the heavy ore accumulated at the center of the bottom of the drum to be discharged to the outside through the second discharge pipe. The output shaft of the second drive motor drives the circular sealing cover to rotate one revolution and then stops. Through the cooperation of the above parts, the equipment can discharge the accumulated heavy ore in a timely manner during continuous operation, thereby improving the overall practicality of the device.

[0027] 2. By setting up a shield, when heavy ore accumulates at the bottom of the drum, the electric push rod can be activated intermittently. The output end of the electric push rod pulls the slide rod, causing the connecting ring to move downward. When the shrinking ring encounters resistance, the connecting ring continues to move downward to compress the shrinking spring, so that the shrinking ring can press on the heavy ore accumulated at the bottom of the drum. This limits the heavy ore outside the shrinking ring, thereby preventing other ore from entering the discharge port of the rotating sleeve during the discharge of heavy ore.

[0028] 3. By setting up unblocking auxiliary components, the output shaft rotates while driving the second large spur gear to rotate, thereby driving the small spur gear to drive the rotary pusher to rotate rapidly through the connecting shaft. The rotary pusher pushes the return frame to pull the auxiliary frame to move laterally back and forth, so that the connecting frame drives the unblocking rod to move laterally back and forth to unblock the inside of the second discharge pipe, thereby preventing the ore from blocking the inside of the second discharge pipe and ensuring the smooth discharge of the second discharge pipe;

[0029] 4. By setting up a circulating swing device, during the horizontal reciprocating movement of the unblocking rod, when the unblocking block comes into contact with the ore, the unblocking block squeezes the auxiliary spring relative to the unblocking sleeve and slides. At the same time, the third drive motor is started. The output end of the third drive motor drives the unblocking sleeve to perform local reciprocating swing, which can actively push up or squeeze down the ore accumulated in the second discharge pipe, thereby improving the unblocking effect of the unblocking rod.

[0030] 5. By setting up an adjustment and actuation mechanism, the first large spur gear rotates synchronously during the rotation of the shaft. The first large spur gear drives the spur gear ring to rotate, which in turn drives multiple material-pulling rods to rotate in a circle. These rods can move the ore pressed against the bottom of the shrink ring, thus cleaning away the ore at the bottom of the shrink ring during the discharge process of the rotating sleeve. The shrink ring gradually returns to its original position under the action of the shrinking spring, thus isolating the heavy ore in the center of the drum from the outside. This prevents other ore from being discharged along with the heavy ore, allowing the equipment to discharge accumulated heavy ore in a timely manner during continuous operation.

The following describes embodiments of the invention based on its overall structure.

[0046] Please see Figures 1-12 In this embodiment of the invention, a novel multi-functional centrifugal concentrator includes a casing 1. A feed pipe 2 is installed at the top of the casing 1. A first discharge pipe 3 is fixedly connected to the discharge port of the casing 1. A rotating sleeve 13 is rotatably connected to the inner side of the casing 1. A drum 8 is fixedly connected to the top of the rotating sleeve 13. A second discharge pipe 7 is fixedly connected to the bottom of the rotating sleeve 13. An L-shaped seat 4 is fixedly connected to the bottom of the casing 1. A first drive motor 5 is installed inside the L-shaped seat 4. A connecting shaft 6 is connected to the output end of the first drive motor 5. A synchronous wheel 11 is installed on the outer wall of both the connecting shaft 6 and the second discharge pipe 7. The outer walls of the two synchronous wheels 11 are equipped with synchronous... The inner side of the rotating sleeve 13 is fixedly connected to the step belt 12 and the connecting sleeve 14. The outer wall of the connecting sleeve 14 is provided with a shield. The outer wall of the rotating sleeve 13 is provided with an adjustment and tossing mechanism that cooperates with the shield. A circular sealing cover 28 is provided at the feed inlet of the rotating sleeve 13. A protective sleeve 25 is fixedly connected inside the rotating sleeve 13. A second drive motor 26 is installed inside the protective sleeve 25. The output end of the second drive motor 26 is connected to an output shaft 27. One end of the output shaft 27 passes through to the outside of the protective sleeve 25 and is fixedly connected to the circular sealing cover 28. A clearing auxiliary component extending into the second discharge pipe 7 is provided inside the protective sleeve 25.

[0047] In this embodiment: a water inlet is provided at the bottom of the drum 8, and a water inlet pipe is provided at the bottom of the casing 1. A gap is left between the drum 8 and the bottom of the casing 1. The drum 8 and the first discharge pipe 3 are sealed with sealing rubber. When the output end of the first drive motor 5 drives the connecting shaft 6 to rotate the synchronous wheel 11, it drives another synchronous wheel 11 to rotate through the synchronous belt 12, thereby driving the second discharge pipe 7 to rotate the drum 8 through the rotating sleeve 13. This causes the drum 8 to generate centrifugal force, which acts on the ore entering the drum 8, thus performing mineral processing. When heavy ore accumulates on the drum... When the drum 8 reaches the bottom, the second drive motor 26 is started. The output shaft 27 of the second drive motor 26 drives the circular sealing cover 28 to rotate, thereby opening the discharge port of the rotating sleeve 13. This allows the heavy ore accumulated at the center of the bottom of the drum 8 to be discharged to the outside through the second discharge pipe 7. After the output shaft 27 of the second drive motor 26 drives the circular sealing cover 28 to rotate one revolution, the operation stops. Through the cooperation of the above-mentioned parts, the equipment can discharge the accumulated heavy ore in a timely manner during continuous operation, thereby improving the overall practicality of the device.

[0048] Please refer to this carefully. Figures 4-8 The shielding device includes an electric push rod 35 installed inside the connecting sleeve 14. The output end of the electric push rod 35 is connected to a slide rod 15. One end of the slide rod 15 extends through to the outside of the connecting sleeve 14 and is fixedly connected to a connecting ring 9. A shrink ring 10 is slidably connected to the inside of the connecting ring 9. Multiple shrink springs 19 are fixedly connected to the top of the shrink ring 10. One end of each shrink spring 19 is fixedly connected to the connecting ring 9. A storage groove matching the shrink ring 10 is opened on the inside of the connecting ring 9. A rectangular groove matching the slide rod 15 is opened on the inside of the connecting sleeve 14.

[0049] In this embodiment: when the heavy ore accumulates at the bottom of the drum 8, the electric push rod 35 can be started intermittently. The output end of the electric push rod 35 pulls the slide rod 15 to drive the connecting ring 9 to move downward. When the shrinking ring 10 is resisted, the connecting ring 9 continues to move downward to squeeze the shrinking spring 19, so that the shrinking ring 10 can press on the heavy ore accumulated at the bottom of the drum 8, thereby limiting the heavy ore outside the shrinking ring 10, thereby preventing other ore from entering the discharge port of the rotating sleeve 13 during the discharge of the heavy ore. When the electric push rod 35 stops running, the second drive motor 26 is started.

[0050] Please refer to this carefully. Figures 4-8The shield also includes a slider 36 slidably connected to the inside of the connecting sleeve 14. A conical sealing cover 16 is fixedly connected to the outer wall of the slider 36. The conical sealing cover 16 fits against the top of the discharge port of the rotating sleeve 13. A suspension frame 40 is fixedly connected inside the connecting sleeve 14. A suspension guide wheel 41 is rotatably connected to the inner side of the suspension frame 40. A support 38 is fixedly connected inside the connecting sleeve 14. A pull rope 37 is fixedly connected to the top of the slider 36. One end of the pull rope 37 is fixedly connected to the slide rod 15. The pull rope 37 fits against the outer wall of the suspension guide wheel 41. A connecting spring 39 is fixedly connected to the top of the slider 36 outside the pull rope 37. One end of the connecting spring 39 is fixedly connected to the support 38. A limiting groove matching the slider 36 is opened on the inner side of the connecting sleeve 14. A through hole with a diameter matching the electric push rod 35 is opened on the inner side of the slider 36.

[0051] In this embodiment: as the slide bar 15 moves downward, the pull rope 37 pulls the conical sealing cover 16 upward, thereby opening the feed port at the top of the rotating sleeve 13. By reversing the above steps, the ore material can be prevented from continuously entering the rotating sleeve 13 and accumulating on the top of the circular sealing cover 28.

[0052] Please refer to this carefully. Figure 6 , Figure 10 , Figure 11 The unblocking auxiliary component includes a connecting shaft 29 rotatably connected to the inner side of the rotating sleeve 13. A small spur gear 31 is fixedly connected to the outer wall of the connecting shaft 29. A second large spur gear 43 is fixedly connected to the outer wall of the output shaft 27 located inside the protective sleeve 25, and the second large spur gear 43 meshes with the small spur gear 31. A rotary pusher 32 is fixedly connected to the bottom of the connecting shaft 29. A rotary pusher column 42 is fixedly connected to the bottom of the rotary pusher 32. A loop frame 34 is sleeved on the outer wall of the rotary pusher column 42. An auxiliary frame 33 is fixedly connected to the inner side of the loop frame 34. One end of the auxiliary frame 33 extends through to the outside of the protective sleeve 25 and is fixedly connected to a connecting frame 22. A unblocking rod 20 is fixedly connected to the bottom of the connecting frame 22. A circulating swing device is provided on the outer wall of the unblocking rod 20.

[0053] In this embodiment: the output shaft 27 rotates while driving the second large spur gear 43 to rotate, thereby driving the small spur gear 31 to drive the rotary pusher 32 to rotate rapidly through the connecting shaft 29. The rotary pusher 42 pushes the loop frame 34 to pull the auxiliary frame 33 to move laterally back and forth, so that the connecting frame 22 drives the unblocking rod 20 to move laterally back and forth to unblock the inside of the second discharge pipe 7, thereby preventing the ore from blocking the inside of the second discharge pipe 7, thus ensuring the smooth discharge of the second discharge pipe 7.

[0054] Please refer to this carefully. Figure 12The circulating oscillator includes an auxiliary ring 21 fixedly connected to the outer wall of the unblocking rod 20. A third drive motor 46 is installed inside the auxiliary ring 21. The output end of the third drive motor 46 extends through to the outside of the auxiliary ring 21 and is fixedly connected to an unblocking sleeve 24. An unblocking block 44 is slidably connected to the inner side of the unblocking sleeve 24. An auxiliary spring 45 is fixedly connected to one end of the unblocking block 44. One end of the auxiliary spring 45 is fixedly connected to the unblocking sleeve 24.

[0055] In this embodiment: during the lateral reciprocating movement of the unblocking rod 20, when the unblocking block 44 comes into contact with the ore, the unblocking block 44 compresses the auxiliary spring 45 to slide relative to the unblocking sleeve 24, and at the same time, the third drive motor 46 is started. The output end of the third drive motor 46 drives the unblocking sleeve 24 to perform local reciprocating swing, thereby actively lifting or squeezing and pushing the ore accumulated in the second discharge pipe 7, thereby improving the unblocking effect of the unblocking rod 20.

[0056] Please refer to this carefully. Figures 4-6 The adjustment mechanism includes a first large spur gear 30 fixedly connected to the top of the connecting shaft 29, a rotating ring 17 rotatably connected to the outer wall of the rotating sleeve 13, a material-pulling rod 18 fixedly connected to the top of the rotating ring 17, and a spur gear ring 23 meshing with the first large spur gear 30 fixedly connected to the bottom of the rotating ring 17. Multiple material-pulling rods 18 are provided, and the multiple material-pulling rods 18 are distributed at equal distances around the rotating ring 17.

[0057] In this embodiment: During the rotation of the connecting shaft 29, the first large spur gear 30 is driven to rotate synchronously. The first large spur gear 30 drives the spur gear ring 23 to drive the rotating ring 17 to rotate, which in turn drives multiple material-pulling rods 18 to rotate in a circle. The multiple material-pulling rods 18 can move the ore pressed against the bottom of the shrinking ring 10, so that the ore located at the bottom of the shrinking ring 10 can be swept away during the discharge of the rotating sleeve 13. As a result, the shrinking ring 10 gradually returns to its original position under the action of the shrinking spring 19. This allows the shrinking ring 10 to isolate the heavy ore in the center of the rotating drum 8 from the outside world, so that other ore will not be discharged together during the discharge of the heavy ore. This allows the equipment to discharge the accumulated heavy ore in a timely manner during continuous operation.

[0058] The following describes a method for using a novel multi-functional centrifugal concentrator, based on the aforementioned method. The method includes the following steps:

[0059] S1. A water inlet is provided at the bottom of the drum 8, and a water inlet pipe is provided at the bottom of the casing 1. There is a gap between the drum 8 and the bottom of the casing 1. The drum 8 and the first discharge pipe 3 are sealed with sealing rubber. When the output end of the first drive motor 5 drives the connecting shaft 6 to drive the synchronous wheel 11 to rotate, it drives another synchronous wheel 11 to rotate through the synchronous belt 12, thereby driving the second discharge pipe 7 to drive the drum 8 to rotate through the rotating sleeve 13, so that the drum 8 generates centrifugal force to act on the ore entering the drum 8, thereby performing mineral beneficiation.

[0060] S2. When the heavy ore accumulates at the bottom of the drum 8, the second drive motor 26 is started. The output shaft 27 of the second drive motor 26 drives the circular sealing cover 28 to rotate, thereby opening the discharge port of the rotating sleeve 13. This allows the heavy ore accumulated at the center of the bottom of the drum 8 to be discharged to the outside through the second discharge pipe 7. The output shaft 27 of the second drive motor 26 drives the circular sealing cover 28 to rotate one revolution and then stops running. Through the cooperation of the above multiple parts, the equipment can discharge the accumulated heavy ore in a timely manner during continuous operation, thereby improving the overall practicality of the device.

[0061] S3. When the heavy ore accumulates at the bottom of the drum 8, the electric push rod 35 can be started intermittently. The output end of the electric push rod 35 pulls the slide rod 15 to drive the connecting ring 9 to move downward. When the shrinking ring 10 is resisted, the connecting ring 9 continues to move downward to squeeze the shrinking spring 19, so that the shrinking ring 10 can press on the heavy ore accumulated at the bottom of the drum 8, thereby limiting the heavy ore outside the shrinking ring 10, thus preventing other ore from entering the discharge port of the rotating sleeve 13 during the discharge of the heavy ore. When the electric push rod 35 stops running, the second drive motor 26 is started.

[0062] S4, while the output shaft 27 rotates, it drives the second large spur gear 43 to rotate, thereby driving the small spur gear 31 to drive the rotary pusher 32 to rotate rapidly through the connecting shaft 29. The rotary pusher 42 pushes the loop frame 34 to pull the auxiliary frame 33 to move laterally back and forth, so that the connecting frame 22 drives the unblocking rod 20 to move laterally back and forth to unblock the inside of the second discharge pipe 7, thereby preventing the ore from blocking the inside of the second discharge pipe 7, thus ensuring the smooth discharge of the second discharge pipe 7;

[0063] S5. As the slide bar 15 moves downward, the pull rope 37 pulls the conical sealing cover 16 upward, thereby opening the feed port at the top of the rotating sleeve 13. By reversing the above steps, the ore can be prevented from continuously entering the rotating sleeve 13.

[0064] S6. During the lateral reciprocating movement of the unblocking rod 20, when the unblocking block 44 comes into contact with the ore, the unblocking block 44 squeezes the auxiliary spring 45 to slide relative to the unblocking sleeve 24. At the same time, the third drive motor 46 is started. The output end of the third drive motor 46 drives the unblocking sleeve 24 to perform local reciprocating swing, which can actively push up or squeeze down the ore accumulated in the second discharge pipe 7, thereby improving the unblocking effect of the unblocking rod 20.

[0065] During the rotation of S7 and the connecting shaft 29, the first large spur gear 30 is driven to rotate synchronously. The first large spur gear 30 drives the spur gear ring 23 to drive the rotating ring 17 to rotate, which in turn drives multiple material-pulling rods 18 to rotate in a circle. The multiple material-pulling rods 18 can move the ore pressed against the bottom of the shrinking ring 10, so that the ore located at the bottom of the shrinking ring 10 can be swept away during the discharge of the rotating sleeve 13. As a result, the shrinking ring 10 gradually returns to its original position under the action of the shrinking spring 19. This allows the shrinking ring 10 to isolate the heavy ore in the center of the rotating drum 8 from the outside world, so that other ore will not be discharged together during the discharge of the heavy ore. This allows the equipment to discharge the accumulated heavy ore in a timely manner during continuous operation.

A water inlet is provided at the bottom of the drum (8), and a water inlet pipe is provided at the bottom of the casing (1). There is a gap between the drum (8) and the bottom of the casing (1). The drum (8) and the first discharge pipe (3) are sealed by sealing rubber. When the output end of the first drive motor (5) drives the connecting shaft (6) to drive the synchronous wheel (11) to rotate, it drives another synchronous wheel (11) to rotate through the synchronous belt (12), thereby driving the second discharge pipe (7) to drive the drum (8) to rotate through the rotating sleeve (13), so that the drum (8) generates centrifugal force to act on the ore that enters the drum (8) for mineral beneficiation. S2. When the heavy ore accumulates at the bottom of the drum (8), start the second drive motor (26). The output end of the second drive motor (26) drives the output shaft (27) to rotate the circular sealing cover (28), thereby opening the discharge port of the rotating sleeve (13) so that the heavy ore accumulated at the center of the bottom of the drum (8) can be discharged to the outside through the second discharge pipe (7). The output end of the second drive motor (26) drives the output shaft (27) to rotate the circular sealing cover (28) once and then stops running. Through the cooperation of the above multiple parts, the equipment can discharge the accumulated heavy ore in a timely manner during continuous operation, thereby improving the overall practicality of the device. S3. When the heavy ore accumulates at the bottom of the drum (8), the electric push rod (35) can be started intermittently. The output end of the electric push rod (35) pulls the slide rod (15) to drive the connecting ring (9) to move downward. When the shrinking ring (10) is resisted, the connecting ring (9) continues to move downward to squeeze the shrinking spring (19), so that the shrinking ring (10) can press on the heavy ore accumulated at the bottom of the drum (8), thereby limiting the heavy ore outside the shrinking ring (10) and preventing other ore from entering the discharge port of the rotating sleeve (13) during the discharge of the heavy ore. When the electric push rod (35) stops running, the second drive motor (26) is started. S4. When the output shaft (27) rotates, it drives the second large spur gear (43) to rotate, thereby driving the small spur gear (31) to drive the rotary pusher (32) to rotate rapidly through the connecting shaft (29). The rotary pusher (42) pushes the loop frame (34) to pull the auxiliary frame (33) to move laterally back and forth, so that the connecting frame (22) drives the unblocking rod (20) to move laterally back and forth to unblock the inside of the second discharge pipe (7), thereby preventing the ore from blocking the inside of the second discharge pipe (7) and ensuring the smooth discharge of the second discharge pipe (7). S5. While the slide bar (15) moves downward, the conical sealing cover (16) is pulled upward by the pulling rope (37), thereby opening the feed port at the top of the rotating sleeve (13). By reversing the above steps, the ore can be prevented from continuously entering the interior of the rotating sleeve (13). S6. During the horizontal reciprocating movement of the unblocking rod (20), when the unblocking block (44) comes into contact with the ore, the unblocking block (44) squeezes the auxiliary spring (45) to slide relative to the unblocking sleeve (24), and at the same time starts the third drive motor (46). The output end of the third drive motor (46) drives the unblocking sleeve (24) to swing locally, so as to actively lift or squeeze and push the ore accumulated in the second discharge pipe (7), thereby improving the unblocking effect of the unblocking rod (20). S7, during the rotation of the connecting shaft (29), the first large spur gear (30) is driven to rotate synchronously. The first large spur gear (30) drives the spur gear ring (23) to drive the rotating ring (17) to rotate, which in turn drives multiple material-pulling rods (18) to rotate in a circle. The multiple material-pulling rods (18) can move the ore pressed on the bottom of the shrink ring (10), so that the ore at the bottom of the shrink ring (10) can be swept away during the discharge of the rotating sleeve (13). Thus, the shrink ring (10) is gradually reset under the action of the shrink spring (19), so that the shrink ring (10) isolates the heavy ore in the center of the drum (8) from the outside world, so that other ore will not be discharged together during the discharge of the heavy ore, so that the equipment can discharge the accumulated heavy ore in a timely manner during continuous operation.
