[0002] A mine is a general term for the shafts, chambers, equipment, ground buildings and structures that form an underground coal mine production system. In the prior art, the air in a coal mine contains a large amount of dust and particles. When collecting the dust, the particulate impurities will affect the exhaust fan, making it impossible to use the exhaust fan for a long time. When the exhaust fan is in use, the exhaust fan cannot be swung left and right, so that the collection range cannot be increased and it is inconvenient to use.

[0003] For example, patent application number CN202410192601.0 discloses a coal dust collection device. The coal dust collection device of the invention, on the one hand, prevents the gas in the borehole from being released into the tunnel, and prevents the gas concentration in the construction tunnel from increasing or exceeding the limit; on the other hand, it can prevent dust from flying in the borehole and the tunnel, and reduce safety hazards. During use, particulate impurities affect the exhaust fan, making it impossible to use the exhaust fan for a long time, and when the exhaust fan is in use, the exhaust fan cannot be allowed to swing left and right, so that the collection range cannot be improved.

[0004] For example, patent application number CN202311103383.0 discloses a coal mine coal dust capture and collection device and its use method. The coal dust is allowed to float downward into the interior of the aggregate box through the discharge port at the bottom of the suction pipe, and the coal dust is collected by the aggregate box. The suction box is directly fixed at the bottom of the equipment, and the coal dust is adsorbed where it is generated to prevent the continuous diffusion of the coal dust. When in use, particulate impurities affect the exhaust fan, making it impossible to use the exhaust fan for a long time. When the exhaust fan is in use, the exhaust fan cannot be allowed to swing left and right, so that the collection range cannot be improved. Utility Model Content

[0026] A rack is provided on one side of the rotating plate 204, and the rack occupies half of the circumference of the rotating plate 204. The rack is meshed with the gear 205. A connecting spring 212 is provided at the bottom of the lifting plate 211, and a fixed plate 213 is provided on the top of the pipeline 202. One end of the lifting plate 211 is movably connected to the fixed plate 213. The second motor 209 is fixedly connected to the pipeline 202 through the fixed plate 213. A vertical rod 214 is provided at the bottom of the lifting plate 211.

[0027] The bottom end of the vertical rod 214 is fixedly connected to the filter plate 203 , and the bottom end of the vertical rod 214 contacts the pipe 202 . A cleaning box 215 is provided at the bottom of the pipe 202 , a delivery pipe 216 is provided on the other side of the exhaust fan 201 , and a water tank 217 is provided on the top of the base 1 .

[0028] See also Figure 1 and 4 Brushes 218 are provided on both sides of the inner wall of the cleaning box 215 . The number of the brushes 218 is two. The bottom end of the filter plate 203 is located between the two brushes 218 and is in contact with the brushes 218 .

[0029] During operation, the exhaust fan 201 is used to allow dust and gas outside to enter the pipe 202 through the exhaust fan 201, and the filter plate 203 in the pipe 202 reduces the amount of particulate impurities entering the pipe 202, and then the gas is transported to the delivery pipe 216, and released through the delivery pipe 216, and the bottom end of the delivery pipe 216 is immersed in the water tank 217, so that the dust in the gas can contact with the liquid, so that the dust is collected in the water tank 217. Since the controller 5 is respectively connected to the first motor 206 and the second motor 209, through The controller 5 starts the first motor 206 and the second motor 209 to work. When the first motor 206 is working, the first motor 206 drives the gear 205 to rotate, so that the gear 205 rotates on one side of the rotating plate 204, and the gear 205 meshes with the gear rail on the surface of the rotating plate 204. The rotation of the gear 205 drives the circular plate and the gear rail to rotate. Since the circular plate is fixedly connected to the exhaust fan 201, the exhaust fan 201 rotates at the same time, and the support rod 207 under the exhaust fan 201 rotates at the same time, so that The torsion spring 208 under the support rod 207 is deformed. When the exhaust fan 201 rotates, the pipes 202 and the conveying pipe 216 on both sides rotate at the same time, so that the angle of the pipe 202 changes. When the rack and the gear 205 are separated, the exhaust fan 201 and the pipe 202 are automatically returned by the torsion spring 208, so that the pipe 202 swings left and right, and the dust collection range is improved. The cleaning box 215 and the sliding block 4 fixedly connected to the pipe 202 swing at the same time and swing in the arc groove 3, and the second motor 209 When in use, the push rod is driven to rotate, and the push rod can be made to rotate around the second motor 209, and can contact with the lifting plate 211, and push the lifting plate 211 to move downward, so that the vertical rod 214 and the filter plate 203 below move downward at the same time, allowing the filter plate 203 to gradually enter the cleaning box 215. Because there is liquid in the cleaning box 215, the filter plate 203 is immersed in the liquid and contacts with the brush 218, so that the filter plate 203 is cleaned to prevent the particles on the surface of the filter plate 203 from affecting the use.
