[0019] Compared with the prior art, the present invention provides a ventilation and dust removal device for tunnel construction, which has the following beneficial effects:

[0020] 1. The ventilation and dust removal device for tunnel construction can drive the first exhaust fan, the first scraper and the second scraper through the first rotating shaft by starting the set servo motor. When the first exhaust fan rotates, the dust inside the tunnel can be absorbed and processed by the first dust removal component, and the filter plate will filter it at the same time, so that the large volume of debris sucked into the inner cavity of the first dust removal component in the tunnel will remain in the inner cavity of the first dust removal component, and the remaining fine dust will remain at the other end of the inner cavity of the first dust removal component, and the filter plate can be removed to clean it. When the first scraper and the second scraper rotate, the outer wall of the filter plate and the inner wall of the first dust removal component will be cleaned at the same time, and the dust and debris accumulated on the inner wall of the first dust removal component and the outer wall of the filter plate can be scraped off, so as to avoid clogging of the filter plate and have a certain cleaning effect on the first dust removal component.

[0021] 2. The ventilation and dust removal device for tunnel construction, when the first rotating shaft rotates, it will also drive the pulley on its outer wall to rotate, at this time the second exhaust fan can be driven to rotate through the belt and the pulley on the other side, at this time the second exhaust fan can collect and process the dust accumulated on the ground in the tunnel, so that it can be collected in the inner cavity of the first collecting box, when the first rotating shaft rotates, it will drive the bevel gear on its outer wall to rotate, at this time the bevel gear on the top of the first connecting shaft can be meshed with it, so as to drive the gear to rotate through the first connecting shaft, the gear can be meshed with the gear ring at this time, so as to drive the third exhaust fan and the brush at the same time, the ground in the tunnel can be cleaned by the provided brush, the dust and debris at the cleaning position can be swept to both sides, which is also convenient for the first collecting box to collect it, when performing dust removal work in the tunnel, the dust in the tunnel and at the bottom of the tunnel can be collected at the same time, so as to effectively improve the dust removal efficiency of the tunnel.

[0022] 3. The ventilation and dust removal device for tunnel construction can draw the dust and debris remaining in the inner cavity of the first dust removal component into the inner cavity of the dust trough when the third exhaust fan rotates. The dust trough is provided, and the first scraper and the second scraper are used to collect the scraped dust into the inner cavity of the second collection box, so that it is convenient for unified cleaning.

[0023] 4. The ventilation and dust removal device for tunnel construction can adjust the height of the second dust removal component by starting the hydraulic lifting rod, and can adjust the angle of the second dust removal component through the telescopic rod by starting the rotating motor, so that the second dust removal component can be adjusted to a suitable height to perform dust removal work on the top of the tunnel, and the telescopic rod can support the second dust removal component, and can drive the second dust removal component to vibrate by starting the vibration motor, and can clean the top of the tunnel with the brush roller, and can sweep away the dust accumulated on the top.

[0024] 5. The ventilation and dust removal device for tunnel construction can discharge the dust falling into its inner cavity into the bottom of the second dust removal component through the arranged groove, and can collect the swept dust into the inner cavity of the first dust removal component through the opened through groove. The rack arranged in the inner cavity of the groove can contact the brush roller when it rotates in the inner cavity of the groove, so that a certain cleaning effect can be achieved on the brush roller, thereby improving the working efficiency of the brush roller.

[0025] 6. The ventilation and dust removal device for tunnel construction can input the water in the inner cavity of the water tank into the return pipe through the set water supply pipe, so that the return pipe can supply water to the atomizing nozzle. When the tunnel is dusted, the dust remaining inside can be reduced to avoid more dust floating in the inner cavity of the tunnel, which is convenient for the staff to work normally in the tunnel. The shielding component can be retracted at any time through the set spring. When the shielding component moves to the top of the atomizing nozzle, the atomizing nozzle can be shielded. When it is idle, the atomizing nozzle can be protected to avoid blockage and damage caused by being idle for too long. After moving the movable rod to the outside of the return pipe, the shielding component can be detached from the top of the atomizing nozzle, so that the atomizing nozzle can be used normally for dust reduction.

[0026] 7. The ventilation and dust removal device for tunnel construction can clean the ground in the tunnel through the cleaning components, and can push the dust and debris accumulated on the ground to the direction of movement of the vehicle body. When the vehicle body completes the dust removal work in the tunnel, the cleaning component can also collect the debris accumulated at the bottom of the tunnel, which is convenient for unified cleaning. The installation slot opened at the cleaning component can be installed with a rag. After the atomizing nozzle performs dust reduction work, the cleaning component can clean the tunnel with the rag installed thereon, which can further improve its cleaning efficiency.

[0027] 8. The ventilation and dust removal device for tunnel construction uses a torsion shaft to enable the cleaning component to rotate the inner side of the vehicle body at all times. By rotating the rotating handle, the bidirectional screw rod can be driven to rotate, so that the top of the support column can be threadedly connected with the bidirectional screw rod. At this time, the support column can move left and right. When the support column moves toward the outside of the vehicle body, the cleaning component can be unfolded, which can adapt to the tunnel size and increase the cleaning range of the cleaning component. When the support column moves toward the inside of the vehicle body, the cleaning range of the cleaning component can be reduced and stored. BRIEF DESCRIPTION OF THE DRAWINGS

After being filtered by the filter plate 5, a part of the large volume of dust and debris will remain in the inner cavity of the first dust removal component 2. After the first scraper 13 rotates, it will drive the second scraper 14 to rotate. At this time, the debris and dust on the outer wall of the filter plate 5 and the inner wall of the first dust removal component 2 can be scraped off. A part of the scraped dust will be scraped into the inner cavity of the dust trough 4 and fall into the inner cavity of the second collection box 15.

[0054] When the servo motor 7 is started, it will drive the bevel gear 20 on the top to rotate at the same time. At this time, the bevel gear 20 on the top can mesh with the bevel gear 20 on the top of the first connecting shaft 19, thereby driving the gear 18 to mesh with the gear ring 21. At this time, the third exhaust fan 16 and the brush 17 can be driven. The third exhaust fan 16 can now draw the dust remaining in the inner cavity of the first dust removal component 2 into the inner cavity of the second collection box 15. When the brush 17 rotates, it will clean the floor of the tunnel, so that the dust and debris on the floor will float to both sides. At this time, the second exhaust fan 10 driven by the pulley 8 and the belt 9 can draw the dust on the floor into the inner cavity of the first collection box 11 for storage;

[0055] The water in the inner cavity of the water tank 31 is injected into the atomizing nozzle 34 through the water pipe 32, the shielding component 35 is separated from the top of the atomizing nozzle 34, and the atomizing nozzle 34 is started. At this time, the inside of the tunnel can be sprayed to reduce dust. When the vehicle body 1 moves, the cleaning component 39 at the bottom can be used with a rag to clean the bottom of the tunnel. At the same time, large-volume debris will be pushed forward to facilitate its accumulation and cleaning.
