After sampling, the materials are prone to sticking and agglomeration, which will cause blockage of the crusher in the sampling system. Blockage will not only prevent the crusher from working properly, but may also further cause blockage failure of the entire system, affecting the accuracy and efficiency of the sampling process, and may even cause equipment damage or shutdown, increase maintenance costs, and affect the stability and continuity of production.

[0039] Preferably, the rotation direction of the second conveyor belt 2 can be automatically controlled according to the moisture content of the coal sampled on the second conveyor belt 2, so as to return the coal with higher moisture content to the first conveyor belt 1, thereby avoiding the crushing box 7 being blocked during sampling.

[0040] Please see the attached Figure 1 -Attached Figure 5In a preferred embodiment, the cleaning assembly includes: a brush roller 10, the brush roller 10 is rotatably mounted on the second conveyor belt 2, a first pulley 12 and a rotating shaft 15 are rotatably mounted on the side of the second conveyor belt 2, and the end face of the rotating shaft 15 is fixedly mounted on the center of the end face of the corresponding round roller 34 through a connecting shaft, the side face of the first pulley 12 is fixedly mounted on the center of the end face of the brush roller 10 through a connecting shaft, a one-way bearing 14 is sleeved on the surface of the rotating shaft 15, the outer ring of the one-way bearing 14 is fixedly sleeved on the second pulley 13, and the surfaces of the first pulley 12 and the second pulley 13 are sleeved on the belt 11;

[0041] Furthermore, the rotation of the round roller 34 will drive the second pulley 13 to rotate through the one-way bearing 14, the rotation of the second pulley 13 will drive the first pulley 12 and the belt 11 to rotate, and the rotation of the first pulley 12 will drive the brush roller 10 to rotate, so as to completely return the coal with a higher moisture content to the first conveyor belt 1.

[0042] Please see the attached Figure 1 -Attached Figure 4 In a preferred embodiment, the support assembly includes: an L-shaped frame 3, there are two L-shaped frames 3, the two L-shaped frames 3 are fixedly mounted on the top of the first conveyor belt 1, and the two L-shaped frames 3 are symmetrically arranged, the horizontal side of the L-shaped frame 3 is rotatably mounted on the vertical side, and the second conveyor belt 2 is fixedly mounted between the two horizontal sides of the L-shaped frames 3, the corresponding vertical side of the L-shaped frame 3 is installed with a first motor 8, and the output shaft of the first motor 8 is installed at the end of the corresponding horizontal side of the L-shaped frame 3, the top of the first conveyor belt 1 is vertically fixed with symmetrically arranged side plates 4, the opposite sides of the two side plates 4 are provided with arc grooves 5, and the two sides away from the second conveyor belt 2 are fixedly mounted with sliding posts 6, and the ends of the two sliding posts 6 are respectively slidably mounted inside the two arc grooves 5;

[0043] Specifically, it is used to support the second conveyor belt 2 and adjust the angle of the second conveyor belt 2 to achieve sampling of the coal transported on the first conveyor belt 1.

[0044] The working principle of the present invention is as follows: when the coal is transported on the first conveyor belt 1 and needs to be sampled, the first motor 8 drives the second conveyor belt 2 to adjust its angle so that the scraper 35 at the end of the second conveyor belt 2 moves downward and can contact the coal, and then the second motor 9 is started to drive the second rotating rod 21 to rotate, and the rotation of the second rotating rod 21 drives the fourth gear 25 and the ring 30 to rotate, and the rotation of the fourth gear 25 drives the first gear 18 to rotate, and the rotation of the first gear 18 drives the first rotating rod 17 to rotate, and the rotation of the first rotating rod 17 drives the round roller 34 and the second conveyor belt 2 to rotate, and the rotation of the second conveyor belt 2 drives the scraper 35 to rotate, so that the coal above the first conveyor belt 1 can be scraped onto the second conveyor belt 2 through the scraper 35. It should be noted that the scraper 35 is arc-shaped;

[0045] When the coal is scraped and lifted onto the second conveyor belt 2 by the scraper 35, the two electrodes 16 will detect the moisture content of the coal. If the moisture content of the coal is low, the current passing through the electromagnet 26 is small, and the repulsive force between the electromagnet 26 and the first magnet 28 is small. Then the first magnet 28 and the fourth gear 25 do not move or move a little, so that the fourth gear 25 is always in contact with the first gear 18 and not in contact with the third gear 20. Then the conveyor belt rotates in the opposite direction to transport the sampled coal through the second conveyor belt 2 to the inside of the crushing box 7 for sample preparation. At this time, the rotation of the round roller 34 will not drive the second pulley 13 to rotate through the one-way bearing 14.

[0046] If the moisture content of the coal is high, the current passing through the electromagnet 26 is large, and the repulsive force between the electromagnet 26 and the first magnet 28 is large. The first magnet 28, the ring 30 and the fourth gear 25 will move a distance. The movement of the rotating ring 30 will cause the vertical side of the L-shaped rod 33 to pass through the open groove 32 and enter the annular groove 31 to limit the ring 30 and the fourth gear 25, so that the fourth gear 25 is in contact with the third gear 20 and no longer in contact with the first gear 18. At this time, the fourth gear 25 rotates to drive the third gear 20 to rotate, and the third gear 20 rotates to drive the second gear 19 to rotate forward. The second gear 19 rotates through the first rotating rod 17 to drive the round roller 34 and the second conveyor Belt 2 rotates forward, and the second conveyor belt 2 rotates forward to send the coal lifted onto the second conveyor belt 2 back to the first conveyor belt 1. It should be noted that due to the limiting effect of the L-shaped rod 33 on the ring 30 and the fourth gear 25, even when the electrode 16 is no longer in contact with the coal with high moisture content, the second conveyor belt 2 will still rotate forward for a while, ensuring that the coal with high moisture content is completely sent back to the first conveyor belt 1. At this time, the rotation of the round roller 34 will drive the second pulley 13 to rotate through the one-way bearing 14. The rotation of the second pulley 13 drives the first pulley 12 and the belt 11 to rotate. The rotation of the first pulley 12 drives the brush roller 10 to rotate, so as to achieve the complete return of the coal with high moisture content to the first conveyor belt 1.

[0047] Then, when the coal with a higher moisture content is sent back to the first conveyor belt 1, the electromagnet 26 no longer generates magnetism, and the elastic force generated by the straight spring 24 causes the fourth gear 25 to return to contact with the first gear 18 again, and no longer mesh with the third gear 20, so that the scraper 35 can lift the coal on the first conveyor belt 1 again;

[0048] In summary, the coal can be sampled by repeating the above steps, and the coal with higher moisture content can be automatically sent back during sampling, thus avoiding the blockage of the crushing box 7 during sampling, ensuring the consistency of coal sampling, and thus improving the use effect of the equipment.

[0049] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
