A first motor 4 is mounted on one side of the frame 1, and the output end of the first motor 4 is connected to one end of one of the conveyor rollers 2.

[0024] A fixed frame 5 is installed at the top of one end of the frame 1. A rotating rod 6 is rotatably fitted inside the fixed frame 5. A second motor 7 is installed on one side of the fixed frame 5. The output end of the second motor 7 is connected to one end of the rotating rod 6. Multiple fixed rods 8 are installed alternately at the top and bottom of the rotating rod 6. A plow block 9 is provided at one end of each of the multiple fixed rods 8. A cross spike 10 is provided on both sides of the plow block 9. A cleaning plate 11 corresponding to the belt 3 is provided at the bottom of the plow block 9. Multiple cleaning rollers 12 corresponding to the gaps between the multiple plow blocks 9 are rotatably fitted inside the fixed frame 5.

[0025] Reference Figure 2 In this embodiment, support plates 13 are provided on both opposite outer sides of the frame 1. Multiple support rollers 14 are rotatably engaged between the two support plates 13, and the multiple support rollers 14 abut against the top of the inner wall of the belt 3. The support rollers 14 provide support to the inside of the belt 3, preventing the belt 3 from denting during coal transportation.

[0026] Reference Figure 3 In this embodiment, one end of the plow block 9 is a conical head, and multiple transverse spikes 10 are respectively inclinedly arranged on both sides of the conical head of the plow block 9. The conical head can separate the coal ore, allowing the coal ore to be transported in a dispersed manner, preventing the coal ore from clogging on the conveyor belt 3.

[0027] Reference Figure 3In this embodiment, the cleaning plate 11 is a V-shaped plate, and the corners of the cleaning plate 11 correspond to the conical heads of the plow block 9. By using the cleaning plate 11, the cleaning plate 11 can scrape off the deposits on the belt 3, and the scraped deposits can move to both sides along the V-shape, so that the cleaning plate 11 can have a continuous and good cleaning effect.

[0028] Reference Figure 3 In this embodiment, a triangular plate 15 is provided on one side of the fixing rod 8. By providing the triangular plate 15, when the plow block 9 separates the coal, the triangular plate 15 can block the fixing rod 8, causing the coal to move to both sides along the triangular plate 15, preventing the coal from hitting the fixing rod 8.

[0030] Working principle: In operation, the first motor 4 is started to drive one of the conveyor rollers 2 to rotate, which in turn drives another conveyor roller 2 to rotate via the belt 3, allowing the belt 3 to transport the coal. During the conveying process of the belt 3, the second motor 7 is started to drive the rotating rod 6 to rotate. The rotation of the rotating rod 6 will drive multiple fixed rods 8 to rotate, adjusting the position of the plow blocks 9 so that some of the plow blocks 9 are above the belt 3. The cleaning plate 11 at the bottom of the plow blocks 9 is attached to the surface of the belt 3, allowing the plow blocks 9 to separate the coal transported by the belt 3. The cleaning plate 11 cleans the surface of the belt 3. While the plow blocks 9 are separating the coal, the cross spikes 10 will hook grass roots, cloth strips and other debris in the coal. After running for a period of time, the second motor 7 is started to drive the rotating rod 6 to rotate, changing the position of the top and bottom fixed rods 8 and the plow blocks 9, adjusting the position of the plow blocks 9 separating the coal, and allowing different cleaning plates 11 to clean different positions on the surface of the belt 3. During the process of changing the position of the plow blocks 9, the plow blocks 9 will pass through the cleaning roller 12, allowing the cleaning roller 12 to clean the debris on the cross spikes 10.
