The upper end of the pump body 16 is provided with a water suction pipe 13, and the lower end of the water suction pipe 13 passes through the left end of the water tank 14 and is located inside the water tank 14. By starting the pump body 16, with the cooperation of the water suction pipe 13 and the three-way connecting pipe 15, the water inside the water tank 14 can be pumped into the dust suppression mechanism 3, and sprayed out after being atomized by the dust suppression mechanism 3. The atomized water can adsorb the dust floating in the air and carry it to the ground, thereby achieving the effect of dust suppression and also achieving the effect of humidifying the air.

[0031] A dust collection box 2 is equipped with an exhaust fan 8 at its upper end, an exhaust pipe 7 at its left end, a dust suction hood 5 at its left end, and a conveying pipe 9 fixedly connected to the right end of the exhaust fan 8. The lower end of the conveying pipe 9 passes through the upper end of the dust collection box 2 and the fine mesh 17 and is located inside the dust collection box 2. By starting the exhaust fan 8, the exhaust pipe 7, the dust suction hood 5, and the conveying pipe 9 can transport dust-laden air into the dust collection box 2. With the help of water added inside the dust collection box 2, the dust in the air can be adsorbed, thereby further achieving the dust reduction effect during the construction process. The simultaneous implementation of multiple dust reduction methods can greatly improve the dust reduction effect of the device. The fine mesh 17 ensures that the dust-laden air entering the dust collection box 2 can fully contact the water inside the dust collection box 2, ensuring the adsorption effect of the water inside the dust collection box 2 on the dust carried in the air.

[0032] Furthermore, a drain pipe 4 is provided at the left end of the dust handling box 2, the motor 12 is fixedly connected to the dust handling box 2 via a motor base provided on it, the pump body 16 is fixedly connected to the right end of the dust handling box 2, the lower end of the water tank 14 is fixedly connected to the mobile trolley 1, the fine mesh 17 is fixedly connected to the upper side inside the dust handling box 2, and an L-shaped support plate 6 is fixedly connected to the exhaust pipe 7, with the right end of the L-shaped support plate 6 fixedly connected to the dust handling box 2.

[0033] Furthermore, the dust suppression mechanism 3 includes a sliding connecting plate 36. A hinge shaft 35 is fixedly connected to the upper end of the sliding connecting plate 36. The hinge shaft 35 is movably connected to one end of the push-pull rod 10. The sliding connecting plate 36 is slidably connected to two limiting rods 37 through two limiting holes inside it. Fixed plates 39 are fixedly connected to both ends of the two limiting rods 37. The lower ends of the four fixed plates 39 are fixedly connected to the upper end of the dust handling box 2. Toothed plates 38 are fixedly connected to both the front and rear ends of the sliding connecting plate 36. The two toothed plates 38 mesh with two gears 34, which are fixedly connected to the upper ends of two spray pipes 33. Each spray pipe 33 is equipped with several atomizing nozzles. Two fixed plates 32 are movably connected to each spray pipe 33. The four fixed plates 32 are fixedly connected to the front and rear ends of the dust handling box 2, respectively. The lower ends of the two spray pipes 33 are fixedly connected to... Two universal swivel connectors 31 are fixedly connected, and both universal swivel connectors 31 are fixedly connected to the upper end of the mobile trolley 1. The right end of each universal swivel connector 31 is fixedly connected to the left end of the three-way connecting pipe 15. The rotation of the output shaft of the motor 12, in cooperation with the push-pull rod 10, the hinge shaft 35 and the push-pull rod 11, can drive the sliding connecting plate 36 to move back and forth in the left and right directions. The reciprocating motion of the sliding connecting plate 36, in cooperation with the toothed plate 38 and the gear 34, can drive the two spray pipes 33 to rotate back and forth within a certain angle range. At this time, the water entering the spray pipe 33 can be sprayed out through the several atomizing nozzles on it, thereby achieving the dust reduction effect in a large area. The cooperation between the fixed plate 39 and the limiting rod 37 can limit the movement direction of the sliding connecting plate 36.

[0034] The working principle of this utility model is as follows:

[0035] When using this device for dust suppression during construction, firstly, add appropriate amounts of water to the dust treatment box 2 and the water tank 14, and start the exhaust fan 8, pump body 16, and motor 12. The pump body 16, in conjunction with the water extraction pipe 13, the three-way connecting pipe 15, and the universal rotating connector 31, draws water from the water tank 14 to the two spray pipes 33. The water is then sprayed out through several atomizing nozzles on both spray pipes 33, achieving the dust suppression effect. During the water spraying process on the two spray pipes 33, the rotation of the output shaft of the motor 12 activates the push-pull rod 10 and the push-pull rod... With the cooperation of the hinge shaft 35 and the 21, the sliding connecting plate 36 can be driven to reciprocate in the left and right directions. At this time, with the cooperation of the toothed plate 38 and the gear 34, the two spray pipes 33 can be driven to reciprocate within a certain angle range, thereby expanding the dust reduction range of the device. By starting the exhaust fan 8, with the cooperation of the exhaust pipe 7, the dust suction hood 5 and the conveying pipe 9, the air carrying dust can be transported to the inside of the dust treatment box 2. With the action of the water added inside the dust treatment box 2, the dust in the air can be adsorbed, thereby further achieving the dust reduction effect in the construction process.
