[0029] Refer to Figures 1-4The shaking mechanism comprises fixed plates 11 fixed symmetrically on both sides of the U-shaped rail 8, sliding grooves 12 formed on both sides of the inside of the ventilation duct 1, the fixed plates 11 being slidingly connected in the sliding grooves 12, a rotating shaft 13 rotatably connected in the inside of the ventilation duct 1, a motor 14 fixed on one side of the ventilation duct 1, the output end of the motor 14 being fixedly connected with one end of the rotating shaft 13, cams 15 fixed symmetrically on the rotating shaft 13, the protruding ends of the cams 15 being capable of abutting against one side of the U-shaped rail 8, and a plurality of springs 16 fixed uniformly on both sides of the fixed plate 11, one end of the springs 16 being fixedly connected with the inner wall of the sliding groove 12.

[0030] In use, the motor 14 is started to drive the rotating shaft 13 to rotate, and the two cams 15 will intermittently impact one side of the U-shaped rail 8 under the guidance of the rotating shaft 13, and when one side of the U-shaped rail 8 is impacted, the fixed plate 11 will slide in the sliding groove 12 and press the springs 16 on the side of the fixed plate 11 away from the cams 15, and when the protruding ends of the cams 15 are separated from one side of the U-shaped rail 8, the springs 16 will rebound to drive the U-shaped rail 8 and the filter plate 9 to continuously shake, so that the dust adhered to the filter plate 9 is shaken off, the filter holes of the filter plate 9 are prevented from being blocked by dust accumulation, the air filtration and the ventilation efficiency in the mine are improved, and the ventilation of the mine is ensured.

[0031] Referring to Figures 5-7 The auxiliary mechanism comprises guide rails 17 fixed alternately in the connecting chamber 3, through holes obliquely formed on both sides of the connecting chamber 3, a connecting plate 18 slidingly connected in the through holes, a sealing strip 19 fixedly connected with one end of the connecting plate 18, the connecting plate 18 and the sealing strip 19 being capable of being clamped in the through holes. The other end of the connecting plate 18 is clamped with a filter plate 20, and the filter plate 20 is slidingly connected in the guide rails 17.

[0032] When the filtered air passes through the inside of the connecting chamber 3, it can also contact the staggered filter plate two 20 again, and the air can be filtered and purified twice through the filter plate two 20, effectively reducing the impurities carried in the air, and greatly improving the air quality. When the filter plate two 20 needs to be replaced, the sealing strip 19 can be pulled to drive the connecting plate 18 and the filter plate two 20 to be pulled out from the inside of the connecting chamber 3, and then the limiting block 23 is manually squeezed to make the limiting block 23 slide in the groove in the plug-in block 21 and compress the spring two 24. At this time, the L-shaped slot 22 on one side of the filter plate two 20 will be out of the limitation of the plug-in block 21, and then the filter plate two 20 can be taken out from the guide rail 17, completing the disassembly and replacement of the filter plate two 20. The operation is simple and convenient, greatly saving the time required for replacing the filter plate two 20, and improving the replacement efficiency. When the replacement is completed, the limiting block 23 is squeezed, the plug-in block 21 is inserted into the L-shaped slot 22, and then the limiting block 23 is released. At this time, the spring two 24 rebounds and slides the limiting block 23 to be clamped in the L-shaped slot 22, completing the installation and fixation of the filter plate two 20.

[0033] With reference to Figure 1 and Figure 3 A T-shaped slot 25 is provided at the top of the ventilation duct 1, and the T-shaped slot 25 is located above the filter plate one 9. A T-shaped cover plate 26 is arranged in the T-shaped slot 25, and the bottom of the T-shaped cover plate 26 is fixedly connected with a magnet 27 on the top surface of the T-shaped slot 25. The magnets 27 on the bottom of the T-shaped cover plate 26 and the top of the T-shaped slot 25 can be attracted to each other.

[0034] When the filter plate one 9 needs to be replaced, the T-shaped cover plate 26 can be pulled upwards to release the magnetic attraction between the bottom of the T-shaped cover plate 26 and the magnet 27 on the top of the T-shaped slot 25. In this way, the T-shaped cover plate 26 is taken out from the T-shaped slot 25, and then the filter plate one 9 can be taken out from the U-shaped rail 8 for disassembly and replacement. The operation is simple and fast, effectively improving the replacement efficiency of the filter plate one 9. When the replacement is completed, the T-shaped cover plate 26 can be arranged in the T-shaped slot 25 again, and the installation and fixation of the T-shaped cover plate 26 can be completed by the magnetic attraction of the magnet 27. Thus, it is convenient for the staff to replace and clean the filter plate one 9, ensuring smooth ventilation in the device and avoiding blockage.

[0035] Working Principle: In operation, motor 6 is first started to drive fan blades 7, generating negative pressure. This negative pressure forces air from the mine into the ventilation duct 1 through inlet 2. Inside the duct, the air is finely filtered by filter plate 9, removing dust and other impurities. The filtered air then enters connecting chamber 3 and is guided by conveyor pipe 4 to outlet duct 5, where it is finally exhausted. This process completes the air exchange and purification within the mine. As the filtered air passes through connecting chamber 3, it comes into contact again with staggered filter plates 20, further purifying the air. The secondary filtration and purification effectively reduces impurities in the air, greatly improving air quality. When the filter plate 20 needs to be replaced, the sealing strip 19 can be pulled to pull the connecting plate 18 and the filter plate 20 out of the connecting chamber 3. Then, the limiting block 23 is manually squeezed, causing the limiting block 23 to slide in the groove inside the insert block 21 and compress the spring 24. At this time, the L-shaped groove 22 on one side of the filter plate 20 will be released from the restriction of the insert block 21, completing the disassembly and replacement of the filter plate 20. The operation is simple and convenient, greatly saving the time required to replace the filter plate 20 and improving the replacement efficiency. After the replacement is completed, the new filter plate 20 is simply engaged with the insert block 21 through the L-shaped groove 22 to complete the installation and fixation of the filter plate 20.

[0036] In routine ventilation and filtration, motor 14 can be started to drive shaft 13 to rotate. Shaft 13 guides two cams 15 to intermittently impact one side of the U-shaped rail 8. When one side of the U-shaped rail 8 is impacted, the fixed plate 11 slides within the sliding groove 12, pressing the spring 16 on the fixed plate 11 away from the cam 15. As the cam 15 continues to rotate, separating its protruding end from one side of the U-shaped rail 8, spring 16 rebounds, causing the U-shaped rail 8 and filter plate 9 to vibrate continuously, thus filtering the filtered air. The large amount of dust adhering to the filter plate 9 is shaken off, reducing the accumulation of dust and preventing the filter holes on the filter plate 9 from becoming clogged. This effectively improves the air filtration and ventilation efficiency in the mine, ensuring smooth ventilation in the mine. The shaken-off dust will automatically fall into the collection box 10 for collection due to gravity. When it is necessary to clean the dust inside the collection box 10, simply remove the collection box 10 from the ventilation duct 1. After cleaning, the collection box 10 can be re-erected inside the ventilation duct 1 via the mounting plate 28, awaiting the next collection.

[0037] When filter plate 9 needs to be replaced, the T-shaped cover 26 can be pulled upwards to release the magnetic attraction between the bottom of the T-shaped cover 26 and the top magnet 27 of the T-shaped groove 25. This allows the T-shaped cover 26 to be removed from the T-shaped groove 25, and then the filter plate 9 can be removed from the U-shaped rail 8 for disassembly and replacement. The operation is simple and quick, effectively improving the replacement efficiency of filter plate 9. After replacement, simply place the T-shaped cover 26 back into the T-shaped groove 25 and use the magnetic attraction of the magnet 27 to complete the installation and fixation of the T-shaped cover 26. This facilitates the replacement and cleaning of filter plate 9 by the staff, ensuring smooth ventilation inside the device and preventing blockage.
