The diaphragm is installed below the jigging chamber, and through the downward movement of the diaphragm, the separation medium will form a periodic up-and-down pulsation, thereby realizing the efficient separation of different density mineral particles.

[0003] This device has the following advantages: high production capacity and small floor area, compact and simple structure; uniform distribution of upward water flow, stable separation effect; the heavy product discharge port is arranged on the movable cone bottom, and the discharge process is smooth and unobstructed. However, its shortcoming is also quite prominent: the power mechanism is arranged below the diaphragm, which is limited by the narrow space, and the disassembly and installation of the parts are not convenient, resulting in great difficulty in maintenance and repair of the equipment. SUMMARY

[0004] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, the present application proposes a multi-section fine coal separation and recovery device of a jigging machine for improving recovery rate, which can realize the rapid separation of the power mechanism from the diaphragm and the rapid movement of the power structure from below the diaphragm to one side of the overall device, which is no longer limited by the narrow space, thereby facilitating the disassembly and installation of the parts, and further bringing convenience to the maintenance and repair of the equipment.

[0005] A multi-stage clean coal separation and recovery device using a jig to improve recovery rate, according to an embodiment of this application, includes: a jig body, the jig body comprising a jig main box, a connecting barrel, a diaphragm, a conical hopper, a drive component, and a base; the jig main box is fixedly connected to the upper part of the base; the connecting barrel is fixedly connected to the bottom of the jig main box; the diaphragm is fixedly connected to the bottom of the connecting barrel; the bottom of the diaphragm is fixedly connected to the upper part of the conical hopper; and the drive end of the drive component is fixedly connected to the bottom of the conical hopper. The device is characterized in that it further includes: a power system maintenance assembly, the power system maintenance assembly comprising a sliding plate, a first sliding plate frame, a second sliding plate frame, and a protective cover; the drive component comprises a first motor, a power box, and a connecting shaft; a shaft head is provided on the upper part of the connecting shaft; and a connection is established between the connecting shaft and the shaft head. A pin is provided, the upper part of the shaft head is fixedly connected to the bottom of the cone bucket, the output end of the first motor is connected to the internal structure of the power box, the connecting shaft is slidably connected to the outer shell of the power box, the connecting shaft is inserted into the bottom side of the shaft head, and the connecting shaft and the shaft head are limited by the pin, the power box is fixedly connected to the sliding end of the sliding plate, the first skateboard frame is fixedly connected to the base, one side of the second skateboard frame is rotatably connected to one side of the first skateboard frame, the sliding plate moves inside the first skateboard frame, the sliding plate moves to the inside of the second skateboard frame through the first skateboard frame, one side of the protective cover is slidably connected to the second skateboard frame, and the other side of the protective cover is inserted into the upper part of one side of the power box, and the protective cover is located above the first motor.

[0006] According to an embodiment of this application, a multi-stage clean coal separation and recovery device for a jig with improved recovery rate has the following advantages: First, the pin is removed. Although the connecting shaft is still inserted inside the shaft head, the sliding end of the sliding plate can drive the first motor, power box, and connecting shaft to move as a whole after the pin is removed. Before this, the protective cover on the upper part of the power box needs to be removed. After removal, the power box no longer limits the protective cover. The second sliding plate frame is rotated and laid flat on the ground. Then, the protective cover is slid away from the first sliding plate frame. The bottom of the protective cover frame is supported on one side of the second sliding plate frame, so that the first sliding plate frame and the second sliding plate frame can move together. The frames are arranged in a straight line. Then, the limiting structure between the sliding plate and the first slide frame is removed, and the sliding plate is slid from inside the first slide frame to the second slide frame. This process will cause the connecting shaft to separate from the shaft head. At the same time, the power box and motor are moved to one side of the jig body. This completely gets rid of the original space constraints and greatly reduces the difficulty of maintenance and repair of the power mechanism. Meanwhile, the protective cover can be inserted and fixed to one side of the power box and located above the first motor, which can protect the first motor. Especially when the diaphragm leaks, it can reduce the corrosion of water to the first motor and effectively ensure the safe operation of the equipment.

[0007] In addition, a jig-type multi-stage clean coal separation and recovery device for improving recovery rate according to an embodiment of this application also has the following additional technical features: According to this application, the sliding plate includes a lead screw, a second motor, and a plate body. The plate body moves inside the first sliding frame. The lead screw is rotatably connected to the base. The second motor is fixedly connected to the base. The output end of the second motor is drivenly connected to the lead screw. The lead screw is threadedly connected to the plate body.

[0008] According to this application, the output end of the second motor is provided with a first bevel gear, and the lead screw is provided with a second bevel gear, wherein the first bevel gear and the second bevel gear are meshed and connected.

[0009] According to this application, the board body is symmetrically provided with first pulleys, and the first pulleys are located inside the first skateboard frame and move.

[0010] According to this application, the plate body is symmetrically provided with locking bolts, and the locking bolts are threadedly connected to the first slide frame.

[0011] According to this application, a first protrusion is provided on one side of the first skateboard frame, and a second protrusion is provided on one side of the second skateboard frame, wherein the first protrusion and the second protrusion are rotatably connected.

[0012] According to this application, the protective cover is provided with a slide, one side of which is fixedly connected to the protective cover, and the other side of which is slidably connected to the second slide frame.

[0013] According to this application, a groove is provided on one side of the power box, and one side of the protective cover is inserted into the groove.

[0014] According to this application, the upper part of the connecting shaft is provided with a plug, the shaft head is provided with a slot, and the plug is inserted into the slot.

[0015] According to this application, a limiting pad and a limiting clip are respectively provided on one side of the pin. The limiting pad is sleeved on the outside of one side of the pin, and the limiting clip penetrates the inside of the pin on one side.

[0016] The core material of the diaphragm in a down-moving diaphragm jig is mainly rubber, with common types being nitrile rubber and polyurethane rubber. Since the diaphragm needs to be agitated at high frequency, it is subjected to large forces during the process and is prone to breakage. Therefore, it is necessary to replace the damaged diaphragm in time. However, due to the limited space of the equipment, it is difficult to disassemble related components during replacement, which greatly reduces the replacement efficiency.

[0017] According to this application, a replacement component is also included, comprising a linear slide rail, a pulley frame, a telescopic frame, and a transmission component. The diaphragm is symmetrically provided with locking buckles. Supports are spaced apart around the conical bucket. A spring is provided at the bottom of each support. The support also has an upright post. The spring is sleeved on the outside of the upright post. The support is slidably connected to the upright post. The bottom of the upright post is fixedly connected to the sliding end of the linear slide rail. The bottom of the telescopic frame is fixedly connected to the sliding end of the linear slide rail. The telescopic end of the telescopic frame is slidably connected to the upright post. The bottom of the spring abuts against the upper part of the sliding end of the linear slide rail, and the upper part of the spring abuts against the bottom of the support. The transmission component is rotatably connected to the sliding end of the linear slide rail and is drively connected to the driving end of the telescopic frame. The pulley frame is fixedly connected to the bottom of the sliding end of the linear slide rail, and the sliding end of the linear slide rail is slidably connected to the base. In operation, first move the drive unit to one side of the jig body using the sliding plate, then loosen the locking buckle on the upper part of the diaphragm to release the diaphragm from the connecting bucket. Next, use the transmission mechanism to control the telescopic frame to descend. During descent, it will press down on the upper part of the support. With the elastic support of the spring, the continuous descent of the telescopic frame will drive the support and the cone bucket to move downwards synchronously, thereby pulling the diaphragm down and separating it from the connecting bucket. After the diaphragm and connecting bucket are separated and sufficient operating space is provided, the telescopic frame stops descending, and the sliding end of the linear guide rail begins to move. Through the linkage between the upright and the spring, the bottom of the upright is limited by the sliding end of the linear guide rail, and the upper part... Limited by the telescopic end of the telescopic frame, the cone bucket and diaphragm are moved to the other side of the jig body. At this time, the sliding end of the linear slide rail gradually moves away from the base, and one side of the pulley frame abuts the ground to form support. The locking buckle between the diaphragm and the cone bucket can be loosened and removed to complete the removal of the old diaphragm and the replacement of the new diaphragm. Afterwards, the linear slide rail is reset to directly below the connecting bucket. The telescopic end of the telescopic frame is gradually raised through the transmission component, and the upper part of the new diaphragm is fitted onto the bottom of the connecting bucket. The two are then fastened with the locking buckle. This operation realizes the quick and convenient replacement of the diaphragm, saves the time spent disassembling related parts, avoids the limitations of working in a confined space, and effectively improves the replacement efficiency.

[0018] According to this application, the linear slide rail includes a first telescopic member and a sliding frame. The first telescopic member is symmetrically arranged. The end of the first telescopic member is fixedly connected to the base. The output end of the first telescopic member is fixedly connected to the sliding frame. The sliding frame is slidably connected to the base. The bottom of the upright is fixedly connected to the sliding frame. The bottom of the spring abuts against the upper part of the sliding frame.

[0019] According to this application, a second pulley is arranged in an array at the bottom of the pulley frame, and a third pulley is arranged on one side of the pulley frame.

[0020] According to this application, the telescopic frame includes a first frame, a second frame, and a threaded rod. One end of the threaded rod is rotatably connected to the second frame, and the other end of the threaded rod is threadedly connected to the first frame. The first frame and the second frame are slidably connected internally. The upper part of the first frame is slidably connected to the upright, and the bottom of the second frame is fixedly connected to the sliding frame. The threaded rod is drive-connected to the transmission component.

[0021] According to this application, the transmission component includes a third motor, a first transmission shaft, and a second transmission shaft. The first transmission shaft is symmetrically arranged and is connected to the threaded rod. The first transmission shaft is rotatably connected to the second frame and the second transmission shaft is rotatably connected to the sliding frame. The third motor is fixedly connected to the sliding frame, and the output end of the third motor is connected to the second transmission shaft. The second transmission shaft is connected to the first transmission shaft.

[0022] The diaphragm is made of rubber, and its characteristics are similar to those of a car tire. If it lacks maintenance for a long time, the rubber oil inside the tire will gradually leak out, leading to rubber cracking and a shortened service life. The diaphragm of a jig not only has this problem, but the situation is even more pronounced. It needs to withstand high-frequency reciprocating oscillation, so the wear rate is already faster. However, currently commonly used jigs are not equipped with a dedicated diaphragm maintenance structure. Once the rubber oil inside the diaphragm is lost, it is very easy to cause cracking and leakage problems, significantly shortening its service life.

[0023] According to this application, a maintenance component is also included, comprising a first telescopic rod, a servo motor, a second telescopic rod, a gripper, a screwing head, a wiping head, a bolt rod, a rotating head, and a spraying component. The first telescopic rod is fixedly connected to the base. One side of the second telescopic rod is rotatably connected to the telescopic end of the first telescopic rod. The servo motor is fixedly connected to the second telescopic rod, and the output end of the servo motor is fixedly connected to the telescopic end of the first telescopic rod. The other side of the second telescopic rod is fixedly connected to the gripper. The second telescopic rod is fixedly connected to the driving end of the screwing head. The screwing end of the screwing head is sleeved outside one side of the bolt rod. The bolt rod is rotatably connected to the wiping head, and one side of the bolt rod is threadedly connected to the rotating head. The gripper grips the outside of the wiping head. The rotating head is rotatably connected to the outside of the connecting bucket. The spraying component is disposed on one side of the base, and the wiping head is inserted inside the spraying end of the spraying component. After the jigging operation is completed, the telescopic end of the first telescopic rod extends, pushing the second telescopic rod, along with the gripper, turning head, and wiping head, to move synchronously, removing the wiping head from inside the sprayed part. Before removal, the spraying end of the sprayed part has been sprayed with curing oil onto the surface of the wiping head. After removal, the second telescopic rod rotates under the drive of the servo motor, turning the wiping head towards the diaphragm side. The distance between the wiping head and the diaphragm is adjusted by the first telescopic rod, and the specific position of the wiping head is adjusted by the second telescopic rod. Then, the wiping head is attached to the side of the rotating head, and the turning head drives the bolt rod to connect with the threaded joint of the rotating head. Next, the wiping head is tightened. Then, the rotating head drives the wiping head to rotate along the outer wall of the diaphragm, evenly applying the maintenance oil to the diaphragm surface. After application, the first and second telescopic rods work together to move the gripper to the vicinity of the wiping head. The gripper's grasping end clamps the wiping head, the bolt rod is unscrewed, and the wiping head is rotated back to its original position and inserted into the spraying end of the spraying component. The entire process achieves mechanized application of diaphragm maintenance oil, which can effectively reduce the loss of rubber oil inside the diaphragm, delay cracking, and thus extend the service life of the diaphragm.

[0035] The power system maintenance component 200 includes a sliding plate 210, a first sliding plate frame 220, a second sliding plate frame 230, and a protective cover 240. The drive component 150 includes a first motor 151, a power box 152, and a connecting shaft 153. It should be noted that the power box 152 includes a reduction gear, an eccentric wheel, a rotating frame, and a housing. The reduction gear is rotatably connected to the housing.

[0047] The core material of the diaphragm 130 in the down-moving diaphragm 130 jig is mainly rubber, with common types being nitrile rubber and polyurethane rubber. Since the diaphragm 130 needs to be agitated at high frequency, it is subjected to large forces during the process and is prone to breakage.

The pulley frame 320 is fixedly connected to the bottom of the sliding end of the linear slide rail 310. The sliding end of the linear slide rail 310 is slidably connected to the base 160. First, the drive unit 150 is moved to one side of the jig body 100 via the sliding plate 210. Then, the locking buckle 131 on the upper part of the diaphragm 130 is loosened, so that the diaphragm 130 is released from the fastening state with the connecting barrel 120. The third motor 341 of the transmission unit 340 drives the threaded rod 333 of the telescopic frame 330 to rotate through the first transmission shaft 342 and the second transmission shaft 343, causing the first frame 331 to extend and retract relative to the second frame 332. This, in turn, presses down on the bracket 141 with the spring 142, causing the cone bucket 140 to separate the diaphragm 130 from the connecting barrel 120. The sliding frame 312 is driven to move by the output end of the first telescopic component 311 of the linear slide rail 310. The second pulley 321 and the third pulley 322 of the pulley frame 320 ensure the stability of the movement. The sliding frame 312 drives the upright 143, the cone bucket 140 and the diaphragm 130 to move to the other side of the jig body 100. After the old diaphragm 130 is removed by the locking buckle 131 and the new diaphragm 130 is replaced, the reverse operation is performed to reset all components and tighten the diaphragm 130 and the connecting bucket 120, avoiding the limitations of working in a narrow space and realizing the quick and convenient replacement of the diaphragm 130.

[0052] According to this application, such as Figure 10 As shown, the transmission component 340 includes a third motor 341, a first transmission shaft 342, and a second transmission shaft 343. The first transmission shaft 342 is symmetrically arranged and is connected to the threaded rod 333. The first transmission shaft 342 is rotatably connected to the second frame 332. The second transmission shaft 343 is rotatably connected to the sliding frame 312. The third motor 341 is fixedly connected to the sliding frame 312.

[0053] The diaphragm 130 is made of rubber, and its characteristics are similar to those of a car tire. If it lacks maintenance for a long time, the rubber oil inside the tire will gradually leak out, leading to rubber cracking and a shortened service life. The diaphragm 130 of the jig not only has this problem, but the situation is even more pronounced. It needs to withstand high-frequency reciprocating oscillation, so the wear rate is already faster. However, currently commonly used jigs are not equipped with a special maintenance structure for the diaphragm 130. Once the rubber oil inside the diaphragm 130 is lost, it is very easy to cause cracking and leakage problems, which significantly shortens its service life.

[0054] According to this application, such as Figure 12 and Figure 13As shown, it also includes a maintenance component 400, which includes a first telescopic rod 410, a servo motor 420, a second telescopic rod 430, a gripper 440, a screwing head 450, a wiping head 460, a bolt rod 470, a rotating head 480, and a spraying component 490.

The wiping head 460 is inserted into the spraying end of the spraying part 490. After the jigging operation is completed, the second telescopic component 413 of the first telescopic rod 410 drives the first rod body 411 to extend relative to the second rod body 412, pushing the fourth rod body 432 of the second telescopic rod 430, along with the gripper 440, the turning head 450, and the wiping head 460, to move, removing the wiping head 460 from the spray box 494 of the spraying component 490. Before removal, the curing oil in the liquid tank 491 is delivered to the spray head 493 by the liquid pump 492 and has been sprayed onto the surface of the wiping head 460. The servo motor 420 drives the fourth rod body 432 to rotate, turning the wiping head 460 towards the diaphragm 130 side. The spacing is adjusted by the first telescopic rod 410, and the output end of the third telescopic component 433 of the second telescopic rod 430 drives the third... The rod 431 is adjusted to position the wiping head 460 so that it fits against the block 481 of the rotating head 480. The output end of the fourth motor 451 of the turning head 450 drives the bolt rod 470 to be threadedly connected and fixed to the block 481. Then, the fifth motor 482 of the rotating head 480 drives the block 481 to rotate along the connecting barrel 120, causing the wiping head 460 to rotate and rub along the outer wall of the diaphragm 130 to evenly apply the curing oil. After completion, the gripper 440 grabs the wiping head 460, the turning head 450 removes the bolt rod 470, and the first telescopic rod 410 and the second telescopic rod 430 work together to reset the wiping head 460 and insert it into the spray box 494, realizing the automated curing of the diaphragm 130, reducing the loss of rubber oil and extending its service life.
