[0002] Coal mine transportation is the process of transporting underground coal resources to the ground through conveyor belts to realize operations such as coal mining, transportation and processing. In coal mine production, a key link is the coal mine transportation system. At present, belt coal conveyors are mainly used for transportation, and the belts are driven by motors to rotate to realize the transportation of coal. In coal mine transportation, coal conveyors usually need to transport large amounts of coal over long distances and for a long time. During use, the coal is often piled unevenly, which may cause uneven force on the conveyor belts and large transportation angles.

[0020] The method for using the safety auxiliary coal conveying equipment for coal mine transportation described in this embodiment is as follows: First, connect all electrical equipment with wires and power them on, then start the first servo motor 9, and control the rotation of the first rotating shaft 3 on the other side of the frame 1 through the reducer 8, thereby controlling the rotation of the driving roller 5, and one side of the conveyor belt 6 is sleeved on the driven roller 4, and the other side is sleeved on the driving roller 5. When the driving roller 5 rotates, the rotation of the conveyor belt 6 is controlled; then pour the coal blocks from one side of the conveyor belt 6, and through the rotation of the conveyor belt 6, the coal blocks are transported from one side of the conveyor belt 6 to the other side. In this process, when the coal blocks are accumulated on a certain section of the conveyor belt 6, the weight of the coal blocks will press the conveyor belt 6 of this section downward. To prevent the conveyor belt 6 from breaking, the conveyor belt 6 is supported by the first supporting roller 11 and the second supporting roller 12 abutting the lower end of the conveyor belt 6. At this time, the moving seat 10 and the moving block 14 move downward, and the spring 16 is in a compressed state, which plays a buffering role.

[0021] During the process of transporting coal blocks, the second servo motor 28 is started, and the second belt 27 is controlled to rotate by the second servo motor 28, thereby controlling the second transmission wheel 26 to rotate, and then controlling the third rotating shaft 25 to rotate. The third rotating shaft 25 drives the connecting cylinder 29 to rotate, and then controls the screen 30 to revolve around the third rotating shaft 25 as the axis. At this time, the screen 30 scoops up the coal blocks on the conveyor belt 6, and the larger coal blocks are filtered out through the screen 30. Through the rotation of the connecting cylinder 29, the larger coal blocks in the screen 30 are transported to the guide platform 31.

[0022] The larger coal blocks are guided into the crushing table 37 through the guide table 31. At this time, the coal blocks fall on the middle part of the top surface of the filter plate 38. Then, the first hydraulic cylinder 33 is started, and the first pressure plate 35 is pushed downward by the first hydraulic cylinder 33, so that the coal blocks on the middle part of the top surface of the filter plate 38 are crushed, and some of the coal blocks will fall to the two ends of the top surface of the filter plate 38. Then, the second hydraulic cylinder 34 is started, and the second pressure plate 36 is pushed downward by the second hydraulic cylinder 34, so that the coal blocks at both ends are crushed for the second time. The crushed coal blocks will fall onto the conveyor belt 6 through the filter plate 38 and continue to be transported to the other side through the conveyor belt 6.

[0023] After the larger coal blocks are crushed, the third servo motor 43 is started, and the third servo motor 43 is used to control the third belt 42 to rotate. The third belt 42 is sleeved on the third transmission wheel 41, so as to control the third transmission wheel 41 to rotate, and then the fourth rotating shaft 40 is controlled to rotate. A rotating plate 44 and a rotating table 45 are installed on the fourth rotating shaft 40, and a rotating rod 46 is connected by rotation between the rotating plate 44 and the rotating table 45. When the fourth rotating shaft 40 rotates, the rotating plate 44 and the rotating table 45 are controlled to rotate, and then the rotating rod 46 and the smoothing roller 47 are controlled to revolve. A gear 49 is installed at the front end of the rotating rod 46, and the gear 49 is meshed with the inner gear ring 50 for transmission, so as to realize the self-rotation of the gear 49, and then the rotating rod 46 and the smoothing roller 47 are controlled to revolve and realize self-rotation while controlling the revolution, so as to smooth the higher coal blocks at both ends of the conveyor belt 6 to prevent the coal blocks from falling.

[0024] When the conveyor belt 6 transports the coal blocks to the other side, the first transmission wheel 17 is controlled to rotate through the first rotating shaft 3 on the other side, thereby driving the first belt 18 to rotate, and then controlling the rotation of the rotating wheel 19, and the second rotating shaft 20 is controlled to rotate through the rotating wheel 19. When the second rotating shaft 20 rotates, the cleaning roller 22 is controlled to rotate, and the driving roller 5 and the cleaning roller 22 are rotated in the same direction through the first belt 18, so as to control the brush 23 to clean the coal slag remaining on the conveyor belt 6; when the coal slag is cleaned, all electrical equipment is powered off.
