[0025] The main function of the filter plate 17 is to filter dust and impurities in the air, clean the air, and after the filter plate 17 completes the air filtration task, the operator can pull the two pull plates 23, which will drive the pull rod 24 and the round plate 25 to slide in the fixed sleeve 22, which provides a sliding track for the pull rod 24 and the round plate 25, maintains their movement direction and position, as the pull rod 24 moves outward, they are pulled out from the inside of the mounting block 18, releasing the locking of the mounting block 18, then by rotating the movable plate 21 to make it parallel to the mounting plate 20, the movable plate 21 is used to adjust the angle of the filter plate 17, when it is parallel to the mounting plate 20, it helps to smoothly take out the filter plate 17 from the filter box 2, and the operator can easily pull the handle 19 to take out the filter plate 17 from the filter box 2.

[0026] Referring to Figure 1 , Figure 2 and Figure 4 , the upper part of the filter box 2 is fixedly connected with the air cylinder 5, the output end of the air cylinder 5 is fixedly connected with the tooth column 6, the upper part of the filter box 2 is fixedly connected with the support seat 16, the inside of the support seat 16 is rotatably connected with the rotating rod 8, the outside of the rotating rod 8 is fixedly connected with the gear 7, the lower part of the gear 7 is meshingly connected with the tooth column 6, the outside of the rotating rod 8 is fixedly connected with the positioning block 9, the outside of the positioning block 9 is fixedly connected with the suction assembly, the suction assembly is used to suck dust and harmful gas, the suction assembly includes the fixed pipe 10, the connecting pipe 11 and the dust cover 12, the two connecting pipes 11 are fixedly connected outside the positioning block 9, the opposite sides of the two connecting pipes 11 are fixedly connected with the fixed pipe 10, one end of the two connecting pipes 11 is fixedly connected with the dust cover 12, the upper part of the moving seat 1 is fixedly connected with the fan 3, the input end of the fan 3 is fixedly connected with the filter box 2, one end of the filter box 2 is fixedly connected with the conveying hose 4, the other end of the conveying hose 4 is fixedly connected with the fixed pipe 10, the bottom of the positioning block 9 is fixedly connected with the limiting rod 14 on both sides, the bottom of the two limiting rods 14 is fixedly connected with the limiting block 15, the inside of the support seat 16 is fixedly connected with the limiting seat 13 on both sides, the two limiting blocks 15 are slidingly connected inside the limiting seat 13.

[0027] The fan 3 is used to generate suction force to drive air flow, so that dust and harmful gas can enter the dust removal system from the dust cover 12. After the fan 3 is started, the dust cover 12 is immediately put into operation. The dust cover 12 is a device for collecting dust and harmful gas. It captures pollutants in the working environment through the suction force of the fan 3. The air containing impurities is sucked in and transmitted to the fixed pipe 10 through the connecting pipe 11. Then, the air is pushed through the delivery hose 4 and finally reaches the inside of the filter box 2. Under the action of the filter plate 17, the impurities in the air are filtered. At the same time, the air cylinder 5 is activated, and the output end of the air cylinder 5 pushes the tooth column 6 to move linearly. The movement of the tooth column 6 drives the gear 7 to rotate, thereby driving the rotating rod 8 and the positioning block 9 to rotate. With the rotation of the positioning block 9, the limiting rod 14 and the limiting block 15 also rotate. The limiting rod 14 and the limiting block 15 are used to control the rotation angle and range of the dust cover 12 to prevent excessive rotation. The limiting block 15 smoothly slides in the limiting seat 13, which provides a track for the sliding of the limiting block 15. The limiting block 15 is ensured to slide in the correct position to control the rotation of the dust cover 12, so as to drive the fixed pipe 10 and the connecting pipe 11 to rotate, thereby driving the dust cover 12 to adjust the angle.

[0028] Working principle: Start the fan 3. Under the action of the fan 3, the dust cover 12 starts to extract dust and harmful gas such as gas and coal dust. The air containing impurities is transported to the fixed pipe 10 through the connecting pipe 11, to the delivery hose 4 through the fixed pipe 10, and to the inside of the filter box 2 through the delivery hose 4. Under the action of the filter plate 17, the air is filtered. At the same time of sucking air, the air cylinder 5 is started. The output end of the air cylinder 5 drives the tooth column 6 to move. The movement of the tooth column 6 drives the gear 7 to rotate. The rotation of the gear 7 drives the rotating rod 8 and the positioning block 9 to rotate. When the positioning block 9 rotates, the limiting rod 14 and the limiting block 15 rotate, so that the limiting block 15 slides in the limiting seat 13. When the positioning block 9 rotates, the fixed pipe 10 and the connecting pipe 11 rotate. The connecting pipe 11 drives the dust cover 12 to rotate, so that the dust cover 12 can rotate to adjust the angle. It can more effectively capture and remove dust on the working surface, and improve the dust removal efficiency. After the filter plate 17 filters the air, pull the two pull plates 23. When the pull plate 23 moves, the pull rod 24 and the circular plate 25 slide in the fixed sleeve 22. The two pull rods 24 move away from the inside of the mounting block 18, so that the mounting block 18 is fixed. Then, rotate the movable plate 21, so that the movable plate 21 and the mounting plate 20 remain horizontal. You can pull the handle 19 to take out the filter plate 17 from the inside of the filter box 2. It is convenient to disassemble the filter plate 17 for periodic cleaning or replacement of the filter plate 17. It can remove dust and impurities on the filter plate 17, and reduce the filtering efficiency of the air flow due to the blockage of the filter plate 17.

[0029] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
