[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas, generally divided into underground coal mines and surface coal mines. When the coal seam is far from the surface, generally choose to dig tunnels underground to mine coal, this is an underground coal mine. When the distance between the coal seam and the surface is very close, generally choose to directly strip the surface soil layer to dig coal, this is a surface coal mine. After the coal mine is collected, it is necessary to remove the impurities in it to ensure the purity of the coal mine. However, in the prior art, the operation of removing impurities from the coal mine is relatively complicated, so it requires more manpower and time, thus increasing the collection cost of the coal mine. Therefore, it is necessary to provide an automated impurity removal device to remove the impurities in the coal mine. Summary of the Invention

[0023] In some embodiments, the impurity removal conveying mechanism 2 includes a conveyor belt 21, a first conveyor roller 22, a second conveyor roller 23 and a conveying motor 24, wherein the first conveyor roller 22 and the second conveyor roller 23 are rotatably arranged in the impurity removal mounting shell 1, the first conveyor roller 22 is located on one side of the separation part 3 on the impurity removal conveying mechanism 2, and the second conveyor roller 23 is located on one side of the impurity discharge part 4 on the impurity removal conveying mechanism 2, and the conveying motor 24 is installed on the impurity removal mounting shell 1, wherein the conveying motor 24 can be individually connected to the first conveyor roller 22 for transmission, the conveying motor 24 can also be individually connected to the second conveyor roller 23 for transmission, or the conveying motor 24 can be simultaneously connected to the first conveyor roller 22 and the first conveyor roller 22 for transmission, the conveyor belt 21 is sleeved on the first conveyor roller 22 and the second conveyor roller 23, and a plurality of C-shaped hanging hooks 5 are arranged on the outer side of the conveyor belt 21, and a plurality of rows of C-shaped hanging hooks 5 are arranged in an array, and impurities in the raw coal are removed by the arranged C-shaped hanging hooks 5, and are driven to the impurity discharge port 13 for discharge through the conveyor belt 21.

[0024] The first conveying roller 22 is located on one side of the separation part 3 of the impurity removal conveying mechanism 2, and the second conveying roller 23 is located on one side of the impurity discharge part 4 of the impurity removal conveying mechanism 2.

[0025] Optionally, the bending direction of the C-shaped material hanging hook 5 is set towards the rotation direction of the conveyor belt 21, so as to hook and carry away the sundries in the raw coal.

[0026] The impurity removal conveyor mechanism 2 is arranged obliquely, and the setting height of the separation part 3 is lower than the setting height of the impurity discharge part 4. Therefore, the scattered coal material will roll towards the discharge port 12 under the action of gravity, while the long strip-shaped impurities will be carried away by the C-shaped material hanging hook 5.

[0027] Among them, the included angle formed by the impurity removal conveyor mechanism 2 and the horizontal plane is 10°-50°. The inclination angle of the above-mentioned impurity removal conveyor mechanism 2 can meet the conveying of the coal material, and the coal material will fall towards the discharge port 12 under the action of its own gravity, so as to prevent the coal material from following the impurity removal conveyor mechanism 2 into the impurity discharge port 13 and being discharged.

[0028] In some embodiments, a cleaning mechanism 6 is arranged in the impurity removal installation shell 1. The cleaning mechanism 6 is arranged on one side close to the impurity discharge part 4. The cleaning mechanism 6 includes a cleaning transmission rod 61, a cleaning motor 62 and a cleaning part 63. The cleaning transmission rod 61 is rotatably arranged in the impurity removal installation shell 1. The cleaning motor 62 is installed on the impurity removal installation shell 1 and is in transmission connection with the cleaning transmission rod 61. The cleaning part 63 is arranged on the cleaning transmission rod 61, and the cleaning part 63 contacts the C-shaped material hanging hook 5. The impurities on the C-shaped material hanging hook 5 are cleaned by the arranged cleaning part 63 to prevent the impurities from following the C-shaped material hanging hook 5 and returning to the separation part 3 again to affect the conveying of the coal material.

[0029] Embodiment 1 of the cleaning part 63: The cleaning part 63 is a cleaning brush. The cleaning motor 62 drives the cleaning transmission rod 61 to rotate, and the cleaning transmission rod 61 drives the cleaning brush to clean the C-shaped material hanging hook 5. On this basis, further, the cleaning transmission rod 61 is arranged with a gap in the impurity removal installation shell 1, and a vibration motor is further arranged on the cleaning motor 62. During use, the vibration motor can further drive the cleaning brush to vibrate, so as to realize the vibration cleaning of the C-shaped material hanging hook 5 and improve the cleaning efficiency.

[0030] Embodiment 2 of the cleaning part 63: The cleaning part 63 is a cleaning roller. A gap groove 631 that fits with the C-shaped material hanging hook 5 is arranged on the cleaning roller. The cleaning motor 62 drives the cleaning transmission rod 61 to rotate, and the cleaning transmission rod 61 drives the cleaning roller to rotate. The inner side wall of the gap groove 631 on the cleaning roller is used to frictionally clean the C-shaped material hanging hook 5.

[0031] The debris cleaning motor 62 and the conveying motor 24 in this scheme can use one motor to connect the first conveying roller 22 and / or the second conveying roller 23 with the debris cleaning transmission rod 61. The first conveying roller 22 and / or the second conveying roller 23 and the debris cleaning transmission rod 61 are connected by a single motor to meet the coordination between the C-shaped hanging hook 5 on the conveyor belt 21 and the debris cleaning piece 63.

[0032] When the present solution is in use, the raw coal is transported to the feed port 11 by a vibrating conveyor so that the raw coal enters the impurity removal installation shell 1, and the conveying motor 24 is started to drive the first conveying roller 22 and the second conveying roller 23 to operate. At this time, the raw coal falls onto the conveyor belt 21 and slides down to the discharge port 12 under the action of gravity for discharge. At the same time, the impurities in the raw coal will be caught by the C-shaped hanging hook 5 and move with the conveyor belt 21 to the direction of the impurity discharge part 4. The impurity removal motor 62 is started to drive the impurity removal transmission rod 61 to rotate, and the impurity removal piece 63 on the impurity removal transmission rod 61 is used to peel off the impurities hung on the C-shaped hanging hook 5, so that the impurities fall to the impurity discharge port 13 for discharge.
