[0022] The spray assembly includes a spray pipe 9, which is installed on the inner top of the collecting box 5. A plurality of spray heads 8 are arranged in the middle of the bottom end of the spray pipe 9. The inlet end of the spray pipe 9 is connected to a first water pump 13 through a delivery hose 14. The first water pump 13 is installed in the inner middle of the sedimentation box 10. Liquid water in the sedimentation box 10 can be extracted by the first water pump 13, and then transported to the spray pipe 9 through the delivery hose 14. Finally, it is sprayed downward through the plurality of spray heads 8, so that the dust sprayed from the dust outlet pipe 4 is sprayed and dusted to prevent the dust from floating back into the external air.

[0023] A crushing assembly is provided in the middle of the inner cavity of the collecting box 5, including a plurality of crushing knives 6. The crushing knives 6 are movably installed in the middle of the inner side of the collecting box 5. The bottom of the crushing knife 6 is connected to a driving motor 7 through a rotating shaft.

[0026] Example 2: Reference Figure 1 - Figure 4 As shown, based on Example 1, a dust suppression device for road, bridge and tunnel construction based on municipal engineering design also includes the following structure: A support column 21 is installed in the middle of the upper end of the water storage tank 15, a support rod 22 is arranged in the middle of the inner side of the support column 21, a spray head 20 is arranged on the top of the support rod 22, and a dust collecting assembly is arranged in the middle of the bottom end of the spray head 20; The dust collecting assembly is in an umbrella-shaped structure, including a dust collecting umbrella cloth 28, a plurality of groups of first umbrella ribs 26 and a plurality of groups of second umbrella ribs 27, the plurality of groups of second umbrella ribs 27 are evenly installed on the inner wall of the dust collecting umbrella cloth 28, the plurality of groups of first umbrella ribs 26 and the plurality of groups of second umbrella ribs 27 are respectively movably connected, a sliding ring 23 is slidably installed on the outer wall of the support column 21, the bottom of the first umbrella rib 26 is movably installed on the upper end surface of the sliding ring 23, the bottom of the second umbrella rib 27 is movably installed on the top edge of the support column 21, and both sides of the bottom end of the sliding ring 23 are A hydraulic rod 24 is provided, and the hydraulic rod 24 is installed at both ends of the bottom of the support column 21. The hydraulic rod 24 is used to drive the sliding ring 23 to perform lifting and sliding movements on the support column 21, so that the dust collecting component of the umbrella structure can be opened or closed. The support rod 22 is installed in the middle of the inner side of the support column 21. A guide channel 25 is provided between the support rod 22 and the support column 21. A guide pipe 29 is provided at the end of the guide channel 25. The guide pipe 29 is installed at an angle, and the end of the guide pipe 29 is located in the inner cavity of the collection box 5.

[0027] Among them, the sliding ring 23 is pushed by two groups of hydraulic rods 24 to perform lifting and sliding movements. When the sliding ring 23 rises, it will push the first umbrella rib 26, thereby pushing the second umbrella rib 27, so that the dust collecting umbrella cloth 28 is driven to be unfolded until a funnel shape is formed at the bottom of the spray head 20. At this time, the dust collecting umbrella cloth 28 can receive and recycle the water mist sprayed by the spray head 20, and the recycled mixed dust droplets are diverted through the diversion channel 25, and finally diverted to the collection box 5 through the diversion pipe 29 for treatment.

[0028] A second water pump 16 is installed in the middle of the inner side of the water tank 15, and a water pipe 19 is provided at the outlet end of the second water pump 16.

[0029] In some examples, the water storage tank 15 is located between the sedimentation tank 10 and the collection tank 5 , and a through hole 17 is provided between the sedimentation tank 10 and the water storage tank 15 to facilitate the mutual flow and replenishment of liquid water in the water storage tank 15 and the sedimentation tank 10 .

[0030] In some examples, a water injection pipe 18 is disposed on the top of the water tank 15 for adding water into the water tank 15 .

[0031] The working principle of the present invention is: During use, the staff moves the device of the present invention into the tunnel through the mobile frame 1, and then turns on the vacuum cleaner 2. At this time, the dust hood 3 will generate suction to suck the dust on the ground, and then transport it to the collection box 5 through the dust outlet pipe 4. At the same time, the first water pump 13 is started to extract the liquid in the sedimentation box 10, and then transport it to the spray pipe 9 through the delivery hose 14. Finally, it is sprayed through multiple groups of spray heads 8, so that the dust sprayed from the dust outlet pipe 4 can be sprayed to reduce dust, so that the dust mixed with liquid water mist falls downward and falls into the inner bottom of the collection box 5; In the process of spraying and dust reduction, the driving motor 7 is driven to drive the crushing blade 6 to rotate, so as to crush the dust in the mixed liquid, prevent the dust from floating on the liquid surface, and make the dust completely crushed and melted into the liquid. Then, the mixed liquid flows into the sedimentation tank 10 through the connecting pipe 11 for sedimentation. The mixed liquid can be filtered and separated by arranging a multi-layer filter screen 12 in the middle of the inner side of the sedimentation tank 10, so as to prevent the dust from clogging the first water pump 13. Through the above structure, the dust on the tunnel floor can be extracted and then reduced through the spray assembly to prevent the dust from floating into the tunnel again, thereby effectively improving the dust reduction effect.

[0032] In addition, by providing a water tank 15, in the process of sucking the dust on the ground through the dust hood 3, the second water pump 16 inside the water tank 15 is started, and the liquid in the water tank 15 can be extracted, and then transported to the spray head 20 located at the top through the water pipe 19 for spraying, so as to spray and reduce the dust above the tunnel. The dust increases in weight when it meets water and falls downward. At this time, the dust collecting umbrella cloth 28 in the unfolded form forms a funnel shape, which can receive the dust mist falling from above, and then guide it into the diversion channel 25, and finally guide it from the diversion pipe 29 at the bottom to the collection box 5 for recovery. Under the spray dust reduction of the spray component, the dust is integrated into the collection box 5 for mixed precipitation.

[0033] During use, the present invention can collect and process dust on the ground and in the air above the tunnel at the same time, thereby effectively improving the efficiency and quality of dust removal in the tunnel.
