For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1 to Figure 2 As shown, a pneumatic drilling vacuum cleaner for mining, comprising:

[0029] The dust collecting bucket 1 is configured as a cylindrical structure as a whole, the bottom of which gradually shrinks into a funnel shape, and a dust suction pipe 11 is provided on the side, and a suction nozzle 12 is fixedly connected to the end of the dust suction pipe 11 away from the dust collecting bucket 1;

[0030] The bucket cover 2 is arranged on the top of the dust collecting bucket 1, and an air inlet 21 and an air outlet 22 are arranged on the bucket cover 2. The air inlet 21 is arranged at the top center of the bucket cover 2, and the air outlet 22 is arranged on the side of the bucket cover 2;

[0031] The multi-stage filter 3 is arranged inside the dust collecting bucket 1, and is provided with three levels from top to bottom, namely, a coarse filter 31, a medium efficiency filter 32 and a high efficiency filter 33;

[0032] Among them, filters at each level can be disassembled and replaced separately;

[0033] The position where the dust suction pipe 11 is connected to the dust collecting bucket 1 in the vertical direction is higher than the position where the multi-stage filter 3 is arranged.

[0034] Air is first sucked in through the air inlet 21 located in the center of the top of the barrel cover 2. The air flows through the multi-stage filter 3 starting from the coarse filter 31, and also includes a medium-efficiency filter 32 and a high-efficiency filter 33, to remove dust and particles of different particle sizes step by step. The cleaned air is discharged through the air outlet 22 on the side of the barrel cover 2. The dust suction pipe 11 on the side sucks in dusty air from the workplace and is guided to the multi-stage filter 3 by the suction nozzle 12, and is released after the same cleaning process.

[0035] By arranging a multi-stage filter 3 inside the dust collecting bucket 1, the capture capacity of dust particles of various sizes is greatly enhanced, and the comprehensiveness of air purification is ensured. The position of the dust suction pipe 11 is higher than the position where the multi-stage filter 3 is arranged, which helps to optimize air flow and filtration efficiency, effectively improve the air quality of the underground working site, and thus reduce the threat to the health of miners.

[0036] In this embodiment, a sound-absorbing and shock-absorbing device 23 is provided on the barrel cover 2, and the sound-absorbing and shock-absorbing device 23 is used to reduce the noise and vibration generated during operation.

[0037] By arranging the silencer and shock absorber 23 on the barrel cover 2, the noise pollution generated by the pneumatic drilling vacuum cleaner is reduced, so that the hearing of the miners is better protected, and the stress and fatigue that may be caused by long-term exposure to a high-noise environment are also reduced. In addition, the reduction of vibration also helps to improve the stability and operating accuracy of the pneumatic drilling vacuum cleaner, thereby extending its service life and improving work efficiency.

[0038] In this embodiment, an air outlet filter device 22A is disposed outside the air outlet 22 , and the air outlet filter device 22A includes a plurality of filter layers.

[0039] By additionally adding an air outlet filter device 22A to the air outlet 22, the air outlet filter device 22A includes several filter layers, so that even very fine particles can be effectively captured, thereby ensuring that the air discharged into the environment is cleaner, which is crucial for protecting the air quality in the workplace, especially in a closed or poorly ventilated mine environment. The air outlet filter device 22A further reduces air pollution in the working environment and helps reduce the risk of respiratory diseases caused by inhalation of dust and harmful particles among miners.

[0040] In this embodiment, the material of the barrel cover 2 is polytetrafluoroethylene, and the edge is configured as a notch-type sealing structure.

[0041] Polytetrafluoroethylene is widely used in environments requiring corrosion resistance and wear resistance due to its excellent chemical stability, high temperature resistance and low friction coefficient. The use of this material ensures that the barrel cover 2 will not be easily damaged when exposed to dust, moisture and other possible corrosive substances for a long time, thereby extending the service life of the pneumatic drilling vacuum cleaner.

[0042] The slotted sealing structure provides a stronger sealing effect to prevent air leakage, ensuring the suction power and efficiency of the pneumatic drilling vacuum cleaner, effectively isolating external pollutants from entering, while preventing the escape of filtered fine particles, thereby enhancing the air purification performance.

[0043] In this embodiment, a telescopic section 11A is provided on the dust suction pipe 11 .

[0044] The telescopic section 11A increases the flexibility of the dust suction tube 11, making it easier to adjust the length and angle to adapt to different working environments and spatial conditions, so that the vacuum cleaner can easily reach hard-to-reach areas, thereby improving cleaning efficiency; and the presence of the telescopic section 11A reduces the physical stress on the tube itself when moving or adjusting the dust suction tube 11, helps to reduce wear and tear, and extends the service life of the dust suction tube 11, thereby reducing maintenance costs, while also ensuring the reliability and performance stability of the dust suction tube 11 during long-term use.

[0045] In this embodiment, a regulating valve 22B is provided at the air outlet 22, and the regulating valve 22B can adjust the air flow and pressure according to working conditions.

[0046] The regulating valve 22B provided at the air outlet 22 can flexibly adjust the air flow and pressure according to different working conditions. By adjusting the air flow and pressure, it can ensure that the best dust removal effect can be achieved in different working environments, improve the adaptability and efficiency of the pneumatic drilling vacuum cleaner, and proper adjustment can reduce energy consumption and further reduce operating costs. In addition, by accurately controlling the air flow, it can also reduce wear and tear, extend the service life, and thus reduce long-term maintenance and replacement costs.

[0047] In this embodiment, the suction nozzle 12 is configured as a replaceable joint.

[0048] The suction nozzle 12 is configured as a replaceable joint, so that the suction nozzle 12 can be quickly and easily replaced after being worn or damaged, without replacing the entire pipeline, thereby improving the convenience of maintenance and reducing maintenance costs. The replaceable joint allows suction nozzles 12 of different types or sizes to be replaced according to different work requirements, increasing the flexibility and applicability of the pneumatic drilling vacuum cleaner, enabling it to more effectively adapt to various working environments.

[0049] In this embodiment, the inner wall of the dust collecting bucket 1 is coated with silicon-based paint.

[0050] Silicone-based coatings have excellent anti-adhesion properties, which help prevent dust and other particulate matter from accumulating on the inner wall of the dust bin 1, thereby maintaining smooth air circulation and improving dust collection efficiency. Silicone-based coatings can also improve the wear resistance and corrosion resistance of the inner wall, extend the service life of the dust bin 1, and reduce maintenance and replacement costs caused by wear or corrosion. Silicone-based coatings are also easy to clean, which can simplify the maintenance of the dust bin 1, maintain stable performance, and further improve the convenience of operation and economic benefits.

[0051] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are within the scope of the present invention.
