When the chain 16 transports the coal, the coal slag mixed in the coal will be discharged through the transmission belt 17, thereby achieving the separation of the coal slag.

[0042] Going further:

[0043] In an optional embodiment, two fixing grooves A21 are symmetrically provided inside the leg B18, and the fixing grooves A21 and the interior of the positioning groove 111 are mutually connected, and a ratchet block 22 is provided inside each fixing groove A21, and a connecting plate A24 is fixedly connected to the surface of the ratchet block 22, and a spring A25 is provided inside the fixing groove A21, and the two ends of the spring A25 are respectively fixedly connected to the connecting plate A24 and the leg B18, and two ratchet plates 23 are symmetrically fixedly connected to the surface of the positioning plate 110, and the ratchet block 22 and the ratchet plate 23 are meshed and connected, and a slider 26 is provided inside the positioning groove 111, and the slider 26 is slidably connected to the leg B18 through the positioning groove 111, and the slider 26 is fixedly connected to the positioning plate 110, and the leg B18 has two limit grooves A27 symmetrically provided inside the limit groove A27 and the fixed The grooves A21 are interconnected, and a positioning rod 28 is arranged inside the limiting groove A27. The positioning rod 28 is slidably connected to the support leg B18 through the limiting groove A27. The end of the positioning rod 28 away from the ratchet block 22 is fixedly connected to a pressure block 29. A limiting groove is provided inside the ratchet block 22.

The fixed block 211 is slidably connected to the positioning rod 28 through the socket 210. The surface of the fixed block 211 is fixedly connected to an insert block 212. The insert block 212 is inserted into the socket 210. A spring C is provided inside the limiting groove A27, and the two ends of the spring C are respectively fixedly connected to the positioning rod 28 and the support leg B18.

[0044] In this embodiment: when the positioning plate 110 moves inside the positioning groove 111, the ratchet plate 23 will repeatedly squeeze the ratchet block 22 due to its shape, and the spring A25 will repeatedly squeeze the ratchet block 22 due to its elastic potential energy, so that the ratchet block 22 is tightly attached to the surface of the ratchet plate 23. When the positioning plate 110 stops at a suitable position, the positioning plate 110 is limited by the shape cooperation of the ratchet block 22 and the ratchet plate 23, thereby strengthening the support for the positioning plate 110 and preventing the positioning plate 110 from sliding down. When it is necessary to return the positioning plate 110 to its original position, the positioning plate 110 is first moved upward inside the positioning groove 111 until the slider 26 and the ratchet block 22 fit each other and squeeze the ratchet block 22. Because the slider 26 is wider than the ratchet plate 23, the ratchet block 22 will slide deeper inside the fixed groove A21, and when the ratchet block 2 When the slider 26 moves to a suitable position, the slider 26 will press the positioning rod 28 through the pressing block 29, and the positioning rod 28 will slide in the limiting groove A27, and the spring C will be squeezed. When the positioning rod 28 is squeezed, the positioning rod 28 will move on the surface of the fixed block 211 in the direction away from the plug block 212 until the plug block 212 slides out of the inside of the socket 210, and the spring A25 will push the ratchet block 22 out due to the elastic potential energy, so that the ratchet block 22 and the ratchet plate 23 are meshed with each other again.

[0045] It should be noted that the material of the insert block 212 is a synthetic plastic with flexibility.

[0046] Going further:

[0047] In an optional embodiment, adjacent surfaces of the two positioning plates 110 are fixedly connected with a fixing plate 31, a fixing groove B35 is opened inside the fixing plate 31, a limiting plate 32 is arranged inside the fixing groove B35, the limiting plate 32 is slidingly connected to the fixing plate 31 through the fixing groove B35, a positioning shaft C is arranged between the two limiting plates 32, the positioning shaft C and the limiting plate 32 are rotatably connected, a cleaning brush 33 is fixedly connected to the surface of the positioning shaft C, two sprockets C34 are symmetrically fixedly connected to the surface of the positioning shaft C, and the sprockets C34 are meshed with the corresponding chains 16, the surface of the limiting plate 32 is symmetrically fixedly connected with two connecting plates B36, the connecting plate B36 is slidingly connected to the fixing plate 31 through the fixing groove B35, two springs B37 are symmetrically arranged inside the fixing groove B35, and the two ends of the spring B37 are respectively fixedly connected to the connecting plate B36 and the fixing plate 31.

[0048] In this embodiment: when the chain 16 rotates, the cleaning brush 33 will be driven to rotate through the sprocket C34, and the cleaning brush 33 will clean the coal ash on the surface of the transmission belt 17, thereby cleaning the surface of the transmission belt 17. When the angle of the chain 16 changes, the chain 16 will squeeze the sprocket C34, so that the limit plate 32 slides inside the fixed groove B35, and the cleaning brush 33 can be tightly attached to the surface of the transmission belt 17 through the elastic potential energy of the spring B37.

[0049] The working principle and use process of the present invention:

[0050] When the inclination angle of the transmission device needs to be adjusted, the motor B112 is connected to an external power source and then started, and the gear A113 will be driven to rotate. When the gear A113 rotates, the gear B114 will be driven to rotate. Through the cooperation of the gear A113 and the gear B114, the tooth groove 115 is used to drive the positioning plate 110 to move inside the positioning groove 111, so that the chain 16 and the transmission belt 17 rotate with the connecting column 13 as the axis. After moving to a suitable angle, the motor A14 is connected to an external power source and then started, so that the sprocket A12 is driven to rotate through the connecting column 13. The rotation of the sprocket A12 will drive the sprocket B19 to rotate through the chain 16, so that the coal falling on the surface of the transmission belt 17 can be transported;

[0051] When the coal falls on the surface of the chain 16, the partition 116 can block the coal because the transmission belt 17 has a certain inclination angle to prevent the coal from being unable to be transported to the inside of the carriage due to gravity. When the chain 16 transports the coal, the coal slag mixed in the coal will be discharged through the transmission belt 17, thereby realizing the separation of the coal slag. When the positioning plate 110 moves inside the positioning groove 111, the ratchet plate 23 will repeatedly squeeze the ratchet block 22 due to its shape, and the spring A25 will repeatedly squeeze the ratchet block 22 due to its elastic potential energy, so that the ratchet block 22 is tightly attached to the surface of the ratchet plate 23. When the positioning plate 110 stops at a suitable position, the positioning plate 110 is limited by the coordination of the shapes of the ratchet block 22 and the ratchet plate 23, thereby strengthening the support for the positioning plate 110 and preventing the positioning plate 110 from sliding down.

[0052] When the positioning plate 110 needs to be returned to its original position, the positioning plate 110 is first moved upward inside the positioning groove 111 until the slider 26 and the ratchet block 22 fit together and the ratchet block 22 is squeezed. Because the slider 26 is wider than the ratchet plate 23, the ratchet block 22 will slide deeper inside the fixing groove A21. When the ratchet block 22 moves, it will drive the fixing block 211 to slide inside the insertion hole 210 until the insertion block 212 is inserted into the insertion hole 210. The ratchet block 22 is positioned by the deformation of the insertion block 212, so that the ratchet block 22 is no longer meshed with the ratchet plate 23, so that the positioning plate 110 can move downward inside the positioning groove 111. Until the slider 26 moves to a suitable position, the slider 26 will squeeze the positioning rod 28 through the pressure block 29, the positioning rod 28 will slide inside the limit groove A27, and the spring C will be squeezed. When the positioning rod 28 is squeezed, the positioning rod 28 will move on the surface of the fixed block 211 in the direction away from the plug block 212 until the plug block 212 slides out from the inside of the socket 210. The spring A25 will push the ratchet block 22 out due to the elastic potential energy, and the ratchet block 22 and the ratchet plate 23 will engage with each other again. When the chain 16 rotates, the cleaning brush 33 will be driven to rotate through the sprocket C34, and the cleaning brush 33 will clean the coal ash on the surface of the transmission belt 17, thereby cleaning the surface of the transmission belt 17.

[0053] When the angle of the chain 16 changes, the chain 16 will squeeze the sprocket C34, so that the limiting plate 32 slides inside the fixing groove B35, and the cleaning brush 33 can be closely attached to the surface of the transmission belt 17 through the elastic potential energy of the spring B37.
