A cavity 41 is provided in the funnel coal bin 10 and at the lower part of the guide plate 22. A second sealing component 42 extending into the guide plate 22 is provided in the cavity 41. The first sealing component 40 includes two gas seals provided on the outer wall of the funnel coal bin 10 and symmetrically distributed on both sides of the n-shaped positioning plate 21. Cylinder 401, and a first sealing plate 402 whose bottom end is connected to the actuator end of the cylinder 401 through a support column and whose top end passes through the n-shaped positioning plate 21, the second sealing component 42 includes a second sealing plate 421 that is slidably connected to the inner wall of the cavity 41 and whose top end extends into the guide rail plate 22, a compression spring 422 provided at the bottom of the inner wall of the cavity 41 and used to elastically support the second sealing plate 421, a limiting guide rod 423 provided at the bottom of the second sealing plate 421, and an electromagnetic ring 424 provided at the bottom of the funnel coal bin 10 and used to limit the limiting guide rod 423.

[0043] It should be noted that, in this embodiment, when the scraper member 35 is disassembled, the guide plate 22 moves outward, and at this time, the cylinder 401 drives the first sealing plate 402 to move upward to seal the position of the guide plate 22 to prevent coal from leaking out;

[0044] Furthermore, when the scraper component 35 is working normally, the lifting rod 33 moves upward, and the compression spring 422 pushes the second sealing plate 421 upward so that the top of the second sealing plate 421 contacts the bottom of the lifting rod 33 to prevent the coal from leaking through the guide plate 22;

[0045] When the scraper component 35 is disassembled, the hydraulic cylinder 311 retracts to the initial position, and the lifting rod 33 drives the second sealing plate 421 to move down into the cavity 41. At this time, the limiting guide rod 423 descends into the electromagnetic ring 424, and the electromagnetic ring 424 limits and locks the limiting guide rod 423.

[0046] The specific process of the present invention is as follows:

[0047] The PLC controller model is "IVC3" and the distance sensor 371 model is "XLC-001.2".

[0048] When the scraper component 35 works normally, the execution end of the lifting component 31 drives the scraper component 35 to move up and down through the lifting rod 33, and the scraper component 35 loosens the coal in the funnel coal bin 10;

[0049] When the scraper component 35 needs to be removed, the scraper component 35 is first moved out of the funnel coal bin 10 by disassembling the displacement device 20. During the movement, the hydraulic cylinder 311 retracts to the initial position. At this time, the driving cylinder 232 drives the extension platform 231, the N-shaped positioning plate 21 and the guide plate 22 to move outward, so that the scraper component 35 is moved out of the funnel coal bin 10. After being moved out, the scraper component 35 is located in the outer cover plate 341. At this time, the unlocking component 34 unlocks the locking component 32, and the scraper component 35 can be removed.

[0050] When the scraper component 35 loosens the coal, the hydraulic cylinder 311 actuator drives the scraper plate 351 upward through the lifting rod 33. At this time, the material stripping plate 352 is in contact with the scraper plate 351. The PLC controller receives the distance data from the distance sensor 371 to the electric cylinder 363 and triggers the electric cylinder 363 when the distance data reaches the set value. The electric cylinder 363 drives the L-shaped stripping plate 361 to move outward. The L-shaped stripping plate 361 slides the material stripping plate 352 until it is perpendicular to the scraper plate 351. At this time, the hydraulic cylinder 311 drives the scraper plate 351 and the material stripping plate 352 downward to drive the coal to move downward, completing one material stripping and loosening operation.

[0051] When unlocking and disassembling, the multiple unlocking push rods 342 are pushed inward at the same time, and the unlocking push rods 342 push the sliding pin 323 inward. At this time, the lifting rod 33 can be removed and the scraper component 35 can be detached;

[0052] When the scraper component 35 is disassembled, the guide plate 22 moves outward, and the cylinder 401 drives the first sealing plate 402 to move upward to seal the position of the guide plate 22 to prevent coal from leaking out;

[0053] When the scraper component 35 works normally, the lifting rod 33 moves upward, and the compression spring 422 pushes the second sealing plate 421 upward so that the top of the second sealing plate 421 contacts the bottom of the lifting rod 33 to prevent the coal from leaking through the guide plate 22;

[0054] When the scraper component 35 is disassembled, the hydraulic cylinder 311 retracts to the initial position, and the lifting rod 33 drives the second sealing plate 421 to move down into the cavity 41. At this time, the limiting guide rod 423 descends into the electromagnetic ring 424, and the electromagnetic ring 424 limits and locks the limiting guide rod 423.

[0055] The above description of the present invention is exemplified in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
