[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Embodiment 1

[0036] See also Figure 1-Figure 4 A bucket wheel device and control method for preventing coal slime from sticking to the bucket wheel machine, comprising a support seat 100, a bucket ring 200 driven by a servo motor is mounted on the side of the support seat 100, a bucket body 300 is mounted on the side of the bucket ring 200 by setting bolts, an air pump 400 is mounted on the side of the support seat 100, the servo motor and the air pump 400 are started, and the bucket body 300 is mounted on the side of the bucket ring 200 by setting bolts. Figure 3 In the middle angle of view, the bucket ring 200 is driven to rotate counterclockwise, so that the bucket ring 200 drives the wheel bucket body 300 to rotate counterclockwise, and the corresponding coal slime removal operation is performed;

[0037] The inside of the bucket body 300 is provided with a processing assembly 500, which includes a hydraulic chamber 501 and a mounting seat 502. A force rod 503 is slidably connected to the top of the hydraulic chamber 501, and a spring 504 is installed at the bottom of the force rod 503. A fixing plate 505 is installed at the top of the support seat 100, and a pressing plate 507 is rotatably connected to the side of the fixing plate 505 by setting a torsion spring block 506. When the bucket body 300 finishes taking the coal slime and continues to rotate counterclockwise, the force rod 503 moves to the pressing plate 507 and is pressed by the pressing plate 507. Because the elastic force of the spring 504 is less than the torsion of the torsion spring in the torsion spring block 506, the pressing plate 507 squeezes the force rod 503 and drives the force rod 503 to slide into the hydraulic chamber 501, and cooperates with the hydraulic chamber 501 slidably connected to the force rod 503, so that the pressure in the hydraulic chamber 501 increases.

[0038] The end of the hydraulic warehouse 501 away from the force-bearing rod 503 is slidably connected to an arc rod 508, and the interior of the mounting seat 502 is equipped with a gas pipeline 509. The side of the wheel bucket body 300 is provided with a through opening, and the gas pipeline 509 passes through the opening. The top of the gas pipeline 509 is rotatably connected to a through rotating shaft 510, and the side of the rotating shaft 510 is fixedly connected to a cross plate 511, which is located on the side of the arc rod 508 and is fixed to the arc rod 508. The bottom of the rotating shaft 510 is fixedly connected to an arc blocking block 512. When the pressure in the hydraulic chamber 501 increases, the arc rod 508 slidably connected to the hydraulic chamber 501 is driven to move, so that the arc rod 508 drives the horizontal plate 511 fixedly connected thereto to rotate, and the horizontal plate 511 drives the rotating shaft 510 fixedly connected thereto to rotate, so that the rotating shaft 510 drives the arc block 512 fixedly connected thereto to rotate, and the originally closed gas pipeline 509 is changed to an open state. At this time, the started air pump 400 can input high-pressure gas into the wheel bucket body 300 through the gas pipeline 509 connected thereto, and blow down the viscous coal slime attached to the inner wall of the wheel bucket body 300; in this way, each wheel bucket body 300 can continue to rotate to a position close to the top after completing the coal slime removal operation, and when the coal slime inside it is dumped out, high-pressure gas can be introduced into the wheel bucket body 300. The viscous coal slime is effectively prevented from adhering to the inner wall of the wheel bucket body 300, making the device easier to use.

[0039] After the coal slime in the bucket body 300 is poured out, the bucket body 300 continues to rotate. At this time, when the force-bearing rod 503 moves to the limit position and cannot move further, the force-bearing rod 503 can apply pressure to the extrusion plate 507 and the torsion spring block 506, so that the torsion spring block 506 drives the extrusion plate 507 to rotate, canceling the restriction on the force-bearing rod 503, and the force-bearing rod 503 can be reset under the action of the spring 504, so that the processing assembly 500 is completely reset to facilitate the subsequent use of the device.

[0040] When in use, start the servo motor and the air pump 400 to Figure 3 When the bucket body 300 has finished taking the coal slime and continues to rotate counterclockwise, the force-bearing rod 503 moves to the extrusion plate 507 and is squeezed by the extrusion plate 507. Because the elastic force of the spring 504 is less than the torsion force of the torsion spring in the torsion spring block 506, the extrusion plate 507 squeezes the force-bearing rod 503 and drives the force-bearing rod 503 to slide into the hydraulic chamber 501, and cooperates with the hydraulic chamber 501 slidably connected to the force-bearing rod 503, so that the pressure in the hydraulic chamber 501 increases, driving the arc rod 508 slidably connected to the hydraulic chamber 501 to move, so that the arc rod 508 drives the horizontal plate 511 fixedly connected thereto to rotate, and the horizontal plate 511 drives the rotating shaft 510 fixedly connected thereto to rotate, so that the rotating shaft 510 drives the arc blocking block 512 fixedly connected thereto to rotate, The originally closed gas pipeline 509 is changed to an open state. At this time, the started air pump 400 can input high-pressure gas into the bucket body 300 through the gas pipeline 509 connected thereto, and blow down the viscous coal slime attached to the inner wall of the bucket body 300; in this way, each bucket body 300 can continue to rotate to a position close to the top after completing the coal slime removal operation, and when the coal slime inside it is poured out, high-pressure gas can be introduced into the bucket body 300; after the coal slime in the bucket body 300 is poured out, the bucket body 300 continues to rotate. At this time, when the force rod 503 moves to the limit position and cannot move further, the force rod 503 can apply pressure to the extrusion plate 507 and the torsion spring block 506, so that the torsion spring block 506 drives the extrusion plate 507 to rotate, canceling the restriction on the force rod 503, and the force rod 503 can be reset under the action of the spring 504, so that the processing assembly 500 is completely reset.

[0041] Embodiment 2

[0042] See also Figure 1-Figure 7On the basis of the first embodiment, an auxiliary processing assembly 600 is arranged inside the wheel bucket body 300, and the auxiliary processing assembly 600 includes a gear 1 601, which is located at the bottom of the arc-shaped block 512 and is in a transmission connection state with the arc-shaped block 512. The bottom of the gas transmission pipeline 509 is rotatably connected with a gear 2 602, and the gear 2 602 is meshed with the gear 1 601. When the arc-shaped block 512 rotates a certain angle, the gear 1 601 connected thereto can be driven to rotate, so that the gear 1 601 drives the gear 2 602 meshed therewith to rotate rapidly. The bottom of the gear 2 602 is transmission-connected with a bevel gear 1 603, and the side of the bucket ring 200 is rotatably connected with a rotating rod 604, and the outer side of the rotating rod 604 is fixedly connected with a bevel gear 2 605, and the bevel gear 2 605 is meshed with the bevel gear 1 603. When the gear 2 602 rotates rapidly, it can drive the bevel gear 1 603 connected thereto to rotate, so that the bevel gear 1 603 drives the bevel gear 2 605 meshing therewith to rotate, and the bevel gear 2 605 drives the rotating rod 604 fixedly connected thereto to rotate.

[0043] The side of the rotating rod 604 is fixedly connected with a screw rod 606, and the side of the bucket ring 200 is fixedly connected with a limit seat 607. The outer side of the screw rod 606 is connected with a sliding block 608 by setting a thread. The sliding block 608 is located inside the limit seat 607 and is in a sliding connection state with the limit seat 607. The side of the sliding block 608 is fixedly connected with a scraper rod 609. When the rotating rod 604 rotates, the screw rod 606 fixedly connected thereto can be driven to rotate. Because the sliding block 608 assembled on the outer side of the screw rod 606 is slidably connected with the limit seat 607, the sliding block 608 slides in the limit seat 607, so that the sliding block 608 drives the scraper rod 609 fixedly connected thereto to move, and the viscous coal slime attached to the inner wall of the wheel bucket body 300 is scraped off. The processing effect of the device is improved. When the arc-shaped block 512 is reset as the processing assembly 500 is reset, the scraper rod 609 can be moved to the initial position to facilitate the next scraping operation.

[0044] During use, on the basis of the first embodiment, when the arc-shaped block 512 rotates a certain angle, it can drive the gear 1 601 connected thereto to rotate, so that the gear 1 601 drives the gear 2 602 meshing therewith to rotate quickly, and the gear 2 602 drives the bevel gear 1 603 connected thereto to rotate, so that the bevel gear 1 603 drives the bevel gear 2 605 meshing therewith to rotate, and the bevel gear 2 605 drives the rotating rod 604 fixedly connected thereto to rotate, so that the rotating rod 604 drives the screw rod 606 fixedly connected thereto to rotate, and because the sliding block 608 assembled on the outer side of the screw rod 606 is slidably connected to the limiting seat 607, the sliding block 608 slides in the limiting seat 607, so that the sliding block 608 drives the scraper rod 609 fixedly connected thereto to move, and the viscous coal slime attached to the inner wall of the bucket wheel body 300 is scraped off; when the arc-shaped block 512 is reset along with the resetting of the processing assembly 500, the scraper rod 609 can move to the initial position.

[0045] Embodiment 3

[0046] See also Figure 1-Figure 8 On the basis of the first and second embodiments, a knocking assembly 700 is provided on the side of the bucket body 300, and the knocking assembly 700 includes a sprocket wheel 1 701, and the sprocket wheel 1 701 is connected to the rotating shaft 510 in a transmission manner. When the rotating shaft 510 rotates at a certain angle, the sprocket wheel 1 701 connected to the rotating shaft 510 can be driven to rotate at a certain angle. A chain 702 is installed on the outer side of the sprocket wheel 1 701, and a sprocket wheel 2 703 is connected to the outer side of the gas transmission pipeline 509 in a rotational manner. The chain 702 is away from one end of the sprocket wheel 1 701 and is installed on the outer side of the sprocket wheel 2 703. The bottom of the sprocket wheel 2 703 is connected to the elastic cam 704 in a transmission manner. When sprocket 1 701 rotates at a certain angle, chain 702 assembled on the outside of sprocket 1 701 cooperates to make sprocket 2 703, which is connected to sprocket 1 701 through chain 702, rotate at a certain angle. Sprocket 2 703 drives elastic cam 704 connected to it to rotate at a certain angle, thereby striking the bucket body 300 and causing it to vibrate to a certain extent, further improving the processing effect of the device.

[0047] When in use, on the basis of Example 1 and Example 2, when the rotating shaft 510 rotates at a certain angle, it can drive the sprocket wheel 1 701 connected to it for transmission to rotate at a certain angle, and cooperate with the chain 702 assembled on the outside of the sprocket wheel 1 701, so that the sprocket wheel 2 703 connected to the sprocket wheel 1 701 through the chain 702 can rotate at a certain angle, and the sprocket wheel 2 703 drives the elastic cam 704 connected to it for transmission to rotate at a certain angle, thereby knocking the wheel bucket body 300 and causing it to vibrate to a certain extent.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
