[0044] By setting the adsorption mechanism 6, the particulate matter and dust in the coal mine can be separated easily through static electricity, and the dust can be collected easily, and the collected dust can also be discharged easily.

[0045] The working principle and use process of the present invention are as follows: the frame 1 and the protective frame 2 can be supported by the supporting legs fixedly connected to the bottom of the frame 1 and the protective frame 2, and a screening mechanism 3 is arranged inside the frame 1, and the dual-axis motor 31 is powered on and started, so that the output shaft on one side of the dual-axis motor 31 can drive the first transmission rod 32 to rotate, and the first transmission rod 32 can drive the third gear 316 to rotate, and the third gear 316 drives the first gear 39 sleeved on the outer walls of the two first rotating rods 38 to rotate through the chain, so that the rotation of the first rotating rod 38 can be realized, and the first turbine blade 37 can be driven to rotate by the first rotating rod 38 when rotating, and the two first supporting plates 36 can support the two first rotating rods 38, so that the frame 1 can be moved to the left and right sides of the frame 1. Internal air supply, through the guide plate 35 fixedly connected to the inside of the frame 1, the coal is conveniently placed into the inside of the frame 1 through the feed port opened at the top of the frame 1, and then passes through the surface of the guide plate 35, so that the wind blown by the first turbine blade 37 can pass through the air holes of the guide plate 35, and then blow the coal sliding on the guide plate 35, so as to achieve air screening, so that large coal will slide down along the guide plate 35, and small particles and dust can be blown away, and then the particles will be blocked by the filter baffle 314 and fall downward, and then can be discharged from the discharge port on the side of the bottom of the frame 1 away from the first set frame 33, and the large coal will fall on the guide block 315, and be discharged through the discharge port on the side of the bottom of the frame 1 close to the first set frame 33, so as to achieve the screening action;

[0046] When the third gear 316 rotates, the chain sleeved on the outer wall of the third gear 316 can drive the second gear 313 sleeved on the outer walls of the three second rotating rods 311 to be connected in transmission, so the three second gears 313 can be rotated, so the three second rotating rods 311 can be rotated, and then the second turbine blades 312 fixedly connected to the outer walls of the second gears 313 can be driven to rotate. At the same time, the second sleeve frame 34 can support the two second support plates 310, and the two second support plates 310 can support the second rotating rods 311, so it is convenient to blow air into the interior of the frame 1 again, but the blown wind will blow onto the guide block 315, so it is convenient to screen the coal that slides down from the guide block 315 again;

[0047] Through the auxiliary mechanism 4, the other output shaft of the dual-axis motor 31 can drive the second transmission rod 46 to rotate. Because the second transmission rod 46 is connected to the third rotating rod 44, the dual-axis motor 31 can realize the rotation of the third rotating rod 44 after starting, and the third turbine blade 45 can be driven to rotate through the third rotating rod 44. At the same time, the third rotating rod 44 is supported by the cross plate 43, thereby effectively realizing that the third turbine blade 45 extracts the air inside the frame 1, and transports it to the inside of the exhaust pipe 42 through the fixed cover 41, and discharges it to the outside of the frame 1, and then cooperates with the use of the screening mechanism 3 to facilitate the discharge of the gas inside the frame 1 to the outside;

[0048] By setting the filter mechanism 5, because the bevel gear fixed on the fourth rotating rod 51 and the bevel gear on the outer wall of the second transmission rod 46 have a transmission ratio of 3:1, the fourth rotating rod 51 can be effectively rotated more slowly, and the rotation of the disc 52 can be driven by the fourth rotating rod 51, so that the disc 52 can drive the disc 52 to move in a circular motion, and the rubber sleeve 54 can be driven to move in a circular motion through the fixed frame 53. A sliding ring 55 is placed between the exhaust pipe 42 and the fixed cover 41, and the inner wall of the sliding ring 55 is fixedly connected with a filter cloth 56, so that the auxiliary mechanism 4 can effectively filter dust when extracting air from the frame 1 to avoid dust discharge. At the same time, the filter cloth 56 is knocked by the rubber sleeve 54 to avoid the problem of clogging of the filter cloth 56, and the pull plate 57 is convenient for taking out the sliding ring 55, so it is convenient to replace or clean the filter cloth 56.

[0049] By setting the adsorption mechanism 6, the protective cover 61 can be supported by the filter baffle 314. Because the second transmission rod 46 is transmission-connected with the fifth rotating rod 65, the second transmission rod 46 can drive the fifth rotating rod 65 to rotate and connect when rotating, and the protective cover 61 can protect the transmission mechanism to prevent a large amount of dust from falling on it and affecting the use effect. Because the outer wall of the fifth rotating rod 65 is fixed with a fixing frame 66, the fixing frame 66 can support the plastic plate 67 and facilitate the movement of the plastic plate 67. Therefore, when the fifth rotating rod 65 rotates, the plastic plate 67 can be moved away from one end of the fixing frame 66 and the iron ring 64 by centrifugal force. Contact is made, and static electricity is generated through friction, which makes it easy to absorb the dust dropped on the filter cloth 56, avoiding the problem of filter cloth 56 being blocked by too much dust, and can also easily collect dust. At the same time, there is a rubber gasket 63 between the iron ring 64 and the fixed cover 41, which avoids the static electricity generated from being transmitted to the fixed cover 41, etc. One end of the wire 68 is connected to the inner wall of the iron ring 64, and the other end of the wire 68 is in contact with the ground. At the same time, it is controlled by a switch 69 in the middle. Therefore, when the dust on the iron ring 64 needs to be discharged after collection, the switch 69 can be turned on, and when the dust needs to be collected, the switch 69 can be turned off.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
