The reversing valve is used to control the direction of gas pumping to achieve gas control, to achieve reciprocating movement of the piston, and to achieve the vibration process; the above-mentioned vibration component 7 has various options and will not be repeated here.

[0035] Specifically refer to the appendix Figure 5 ; A vibrating rod body 204 is fixedly connected to the inner wall of the dust removal installation box 201.

The vibrating rod body 204 is made of a rigid material, which can conduct power to the surface of the dust removal filter cylinder 203 to achieve efficient vibration dust removal; and through the communication between the air outlet pipe and the air outlet hole during the reciprocating cycle of the vibrating installation cylinder 701, the air blowing holes are linearly distributed along the vibrating rod body 204 and are consistent with the axial direction of the dust removal filter cylinder 203, and pressure gas can be blown out through a plurality of air blowing holes to complete the secondary cleaning of the surface of the dust removal filter cylinder 203, further improving the cleaning effect of the surface of the dust removal filter cylinder 203 and ensuring the smooth flow of subsequent gas.

[0036] Among them, the air pumping component is communicated with a gas storage tank body through a spare connecting pipe. An electric control valve is arranged in the spare connecting pipe. A gas detection component is arranged in the ventilation main pipe 3. Both the gas detection component and the electric control valve are electrically connected to a central controller.

[0037] Specifically refer to the appendix Figure 6; As one of the preferred driving methods, the driving assembly 6 includes a driving mounting cylinder 602. The driving mounting cylinder 602 is connected to the driving rotating shaft 2031 through a one-way bearing 601.

[0038] Specifically, reference can be made to the appendix Figure 1 ; The ventilation device further includes a fixed mounting frame. A first conveying component 5 is provided on the inner wall of the fixed mounting frame. The dust removal component 2 is controlled to move directionally through the first conveying component 5. A second conveying component 4 is provided on the side wall of the dust removal component 2. The end of the ventilation branch pipe 1 is controlled to move directionally through the second conveying component 4. By providing the first conveying component 5 and the second conveying component 4, the end of the ventilation branch pipe 1 can be pushed towards the heading face direction to make the distance between the end of the ventilation branch pipe 1 and the heading face consistent, so as to meet the requirements of construction ventilation at the heading face; in the traditional operation process, a retractable ventilation hose is usually hung at the end, and manual adjustment is required. Due to the operation requirements for the distance between the exhaust ventilation and the heading face (the distance between the two is not less than 5 meters), the traditional manual operation is more cumbersome, reducing the operation efficiency; and the traditional method can only achieve single-dimensional adjustment by moving the ventilation hose at the end. By this method, two-dimensional distance adjustment can be achieved, with a longer adjustment distance, better effect, and automatic operation, improving the operation efficiency.

[0039] As an optional conveying method, the first conveying component 5 includes a conveying lead screw 501, which is rotatably connected to the inner wall of the fixed mounting frame.

A driving unit is provided between the driving rotating shaft 2031 and the conveying lead screw 501 for controlling the directional movement of the dust removal component 2, and a driving unit is provided on the surface of the dust removal component 2. The driving unit includes a first gear 503. The first gear 503 is threadedly connected to the conveying lead screw 501 and is rotatably connected to the outer wall of the dust removal component 2. A second gear 5032 is fixedly connected to the outer wall of the driving rotating shaft 2031. The second gear 5032 is connected to the first gear 503 through a power transmission member 5031. During the intermittent rotation of the driving rotating shaft 2031, the power can be transmitted to the first gear 503 through the second gear 5032 and the power transmission member 5031 to drive it to rotate. During the rotation of the first gear 503, it can cooperate with the conveying lead screw 501 to drive it to linearly move along the conveying lead screw 501 to achieve the driving process. The power transmission member 5031 can be selected as a speed-changing gearbox, which can adjust the transmission coefficient of the gears to control the moving speed of the dust removal component 2 according to the construction requirements.

[0040] Specifically, reference can be made to Appendix Figure 1 , Appendix Figure 3 and Appendix Figure 6 ; As an optional conveying method, the second conveying component 4 includes a conveying mounting plate 402. A scissor expansion frame 401 is provided at the lower end of the conveying mounting plate 402. The first rotating joint of the scissor expansion frame 401 is rotatably connected to the conveying mounting plate 402. The second rotating joint of the scissor expansion frame 401 is fixedly connected to the end of the ventilation branch pipe 1. A control rack 403 is slidably connected to the inner wall of the conveying mounting plate 402. The lower end of the control rack 403 is rotatably connected to the third rotating joint of the scissor expansion frame 401. The scissor expansion frame 401 includes a plurality of scissors rod assemblies arranged in parallel, and the middle rotating part is a rotating joint. The third rotating joint is located at a position close to the dust removal component 2. The first rotating joint is located between the second rotating joint and the third rotating joint.

The end of the second rotating joint expands and contracts to drive the movement of the end of the ventilation branch pipe 1. The third rotating joint and the lower end of the control rack 403 can move synchronously to serve as a driving function.

[0041] In the process of controlling the linear movement of the tooth plate 403, the third rotating joint can be driven to move toward the dust removal component 2. At this time, the scissor-type telescopic frame 401 can be extended as a whole, thereby controlling the expansion of the ventilation branch pipe 1; it should be noted here that the ventilation branch pipe 1 includes a positioning ring 102 and a soft cloth 101, which are arranged alternately, and the end of the second rotating joint is fixedly connected to the positioning ring at the end of the ventilation branch pipe 1 to drive the expansion of the ventilation branch pipe 1. By setting the scissor-type telescopic frame 401, its telescopicity is small after contraction, and it is easy to control; a ratchet 404 is fixedly connected to the end of the vibrating telescopic rod 702, and the ratchet 404 is located at the upper end of the control tooth plate 403 and cooperates with it, wherein the ratchet 404 moves in the first direction. When the pawl 404 moves, that is, moves toward the direction of the dust removal component 2, it can drive the control tooth plate 403 to move synchronously; when the pawl 404 moves in the second direction, that is, away from the dust removal component 2, it can automatically rotate at this time, and will not drive the control tooth plate 403 to move, and the cycle operation can be realized to realize the control process. The pawl 404 is a prior art, which can cooperate with the control tooth plate 403 to drive unidirectional linear movement, wherein the base part of the pawl 404 is threadedly connected to the fixed connecting rod 604, and the pawl 404 can be installed by rotating the base part of the pawl 404, and it can be adjusted to a higher position so that it can be staggered with the control tooth plate 403. At this time, it will not contact the control tooth plate 403, and will not control the scissors-type telescopic frame 401 to extend, and the control process can be realized.

[0042] During the working process of the present invention, ventilation and dust removal of mine excavation face processing is taken as an example, wherein gas mixed with dust enters from the ventilation branch pipe 1, and passes through the dust removal component 2 and the ventilation main pipe 3 in sequence to be finally discharged, and the gas performs dust removal operation in the dust removal component 2, wherein the gas enters the dust removal installation box 201 from the bottom end of the dust removal component 2, and the gas flows to the surface of the dust removal filter cartridge 203 for filtration, and the filtered gas is discharged from the central position of the dust removal filter cartridge 203, and finally flows out from the ventilation main pipe 3; and the dust removal filter cartridge 203 can be gradually rotated, so that different positions on the surface of the dust removal filter cartridge 203 can correspond to the lower end opening, thereby avoiding blockage due to long-term filtration and ensuring the efficiency of gas filtration.

[0043] In addition, by setting up the vibration component 7, the vibration rod body 204 can be driven to vibrate during the reciprocating movement of the vibration piston 703 and the vibration telescopic rod 702. The vibration rod body 204 is against the outer wall of the dust filter cylinder 203, and it is located on the side where the dust filter cylinder 203 rotates. During the rotation of the dust filter cylinder 203, the vibration rod body 204 can shake off the dust adhering to the surface of the dust filter cylinder 203, and drop it from the bottom into the collection box 1031, completing the collection process and realizing the cleaning of the rotating dust filter cylinder 203 to ensure its continuous cleaning ability.

[0044] When the gas detection component in the ventilation main pipe 3 detects that the gas concentration in the ventilation main pipe 3 exceeds the standard, the electric control valve in the standby connection pipe is opened at this time. At this time, the protective gas in the gas storage tank can be pumped through the vibration component 7 and finally blown out from the vibration rod body 204, mixed with the internal gas to reduce the content of internal gas, avoid the occurrence of explosion hazards, and the mixing effect of the gas blown out from multiple places is better; the air blowing holes on the surface of the vibration rod body 204 are tangent to the dust removal and filtration cylinder 203, and the blown gas can further remove the dust remaining on the surface of the dust removal and filtration cylinder 203, enhance the cleaning efficiency of the dust removal and filtration cylinder 203, and improve the dust filtration effect of the dust removal and filtration cylinder 203.

[0045] During the vibration of the vibration component 7, the vibration telescopic rod 702 reciprocates. During this process, the dust removal and filtration cylinder 203 can be controlled to rotate unidirectionally through the driving component 6 to realize the control process; through components such as the first conveying component 5, the dust removal component 2 can be controlled to move directionally, and through the second conveying component 4, the end of the ventilation branch pipe 1 can be controlled to move directionally. By controlling the positions of the two, the distance between the air inlet at the end and the heading face can be kept consistent, meeting the operation requirements and ensuring normal air extraction, ventilation and dust removal.
