[0002] The development of cities is inseparable from construction. Many construction sites are located around urban residential areas. The construction of the sites requires sand, cement, and soil. These fine dusts are very easy to be blown up by the wind, threatening the health of construction workers, affecting the work efficiency of construction sites, polluting the urban environment, and seriously affecting the lives of surrounding residents.

[0003] The task of dust reduction is urgent. In engineering construction, most dust reduction devices use fog guns. The fog guns adopt atomization dust capture technology, use less water, can also increase the moisture in the air, and reduce the harm of flying dust to the body. However, at present, the spray is not fine enough, which will cause the road surface to be slippery and affect the operation safety. The dust reduction effect is not ideal. And most of the bases of the fog guns used are fixed on the surface of the water tank, and the fog gun body cannot better adjust its spray distance and angle, resulting in a narrow spray range and being difficult to match the spraying requirements of a wider area.

[0004] In view of this, we have introduced a dust reduction device for engineering construction. Content of the Utility Model

Specific implementation manner

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution: a dust reduction device for engineering construction, including a water tank 1, a water inlet 2 is opened on the outer side of the water tank 1, a hydraulic cylinder 3 is fixedly installed on the outer side of the water tank 1, a special-shaped plate 4 is fixedly installed on the top of the hydraulic cylinder 3, and an atomization mechanism 5 is arranged on the special-shaped plate 4.

[0026] In an embodiment of the present utility model, the atomization mechanism 5 includes an air outlet cylinder 50 hinged inside a special-shaped plate 4. An L-shaped frame 51 is fixedly installed on the outer side of the air outlet cylinder 50. A servo motor 52 is fixedly installed inside the L-shaped frame 51. A rotating shaft 53 is fixedly installed at the output end of the servo motor 52. The rotating shaft 53 is rotatably installed inside the air outlet cylinder 50. A brush rod 54, a brush rod 54 is fixedly installed on the outer wall of one end of the rotating shaft 53. The end of the brush rod 54 away from the servo motor 52 slides and fits the outer wall of the air outlet cylinder 50. A fan 55 is fixedly installed on the outer side of the rotating shaft 53. The fan 55 is located inside the air outlet cylinder 50. An atomizing fan 56, an atomizing fan 56 is fixedly installed at the end of the rotating shaft 53 away from the servo motor 52. A nozzle 57 is fixedly installed on the outer side of the air outlet cylinder 50. A hose 58 is fixedly installed on the outer side of the nozzle 57. The end of the hose 58 away from the nozzle 57 is fixedly installed inside the water tank 1. When dust suppression work is required at the construction site, the water tank 1 is filled with water through the water inlet 2. The water is pumped into the hose 58 through the water pump on the device (the water pump is an existing device of the prior art, so it will not be elaborated here). The hose 58 starts to absorb water and fills up at the water storage pipe of the air outlet cylinder 50. The centers of the circular cross-sections of the servo motor 52, the rotating shaft 53, the fan 55, and the atomizing fan 56 are coaxial. When the servo motor 52 is turned on, the rotating shaft 53 rotates, and the brush rod 54 starts to rotate. Then the brush rod 54 cleans the round hole at the base of the air outlet cylinder 50, making the air inlet more unobstructed. Further, multiple groups of nozzles 57 are equally spaced in a circumferential array with the center of the circular cross-section of the rotating shaft 53 as the array center, and the movement trajectories of the nozzles 57 and the atomizing fan 56 do not intersect. Further, four groups of hydraulic cylinders 3 are provided, and the four groups of hydraulic cylinders 3 are respectively arranged between the water tank 1 and the special-shaped plate 4. Further, when the rotating shaft 53 rotates, the fan 55 and the atomizing fan 56 are driven to rotate synchronously. The fan 55 transmits the wind force to the nozzle 57. The nozzle 57 initially sprays the water flow. After passing through the rapidly rotating atomizing fan 56, a more divergent and fine water mist is sprayed, which adheres to the fine dust and settles the dust through the action of gravity, achieving a better dust suppression effect.

[0027] In an embodiment of the present utility model, an adjusting mechanism 6 is provided on the outer side of the water tank 1. A telescopic column 61 is hingedly installed on the outer side of the special-shaped plate 4. One end of the telescopic column 61 away from the special-shaped plate 4 is fixedly installed with a crescent-shaped frame 62, and the outer side of the crescent-shaped frame 62 is slidably connected to the arc-shaped outer wall of the air outlet cylinder 50. When it is necessary to replace the area or adjust the spraying distance angle, the height is adjusted to the required height through the hydraulic cylinder 3, the telescopic column 61 expands and contracts, driving the crescent-shaped frame 62 to slide and adjust the angle, making it more convenient for high-frequency adjustment. Further, a pushing seat 7 is fixedly installed on the outer side of the water tank 1. Multiple universal wheels 8 are fixedly installed at the bottom of the pushing seat 7. Multiple groups of universal wheels 8 are respectively arranged at the four corners of the bottom of the pushing seat 7. The pushing seat 7 can also be manually pushed to adjust the direction through the universal wheels 8.

[0028] Working principle: When dust suppression work is required at the construction site, the water tank 1 is filled with water through the water inlet 2, and the water is pumped into the hose 58 through the water pump on the device. The hose 58 starts to absorb water and is filled at the water storage pipe of the air outlet cylinder 50. The servo motor 52 is turned on, so that the rotating shaft 53 rotates, and then the brush rod 54 starts to rotate. Thus, the brush rod 54 cleans the round hole at the base of the air outlet cylinder 50, making the air inlet more unobstructed. Further, when the rotating shaft 53 rotates, it drives the fan 55 and the mist outlet fan 56 to rotate synchronously. The fan 55 transmits the wind force to the nozzle 57, and the nozzle 57 initially sprays the water flow. Through the rapidly rotating mist outlet fan 56, a more divergent and fine water mist is sprayed, which adheres to the fine dust and suppresses dust through the action of gravity, achieving a better dust suppression effect. When it is necessary to change the area or adjust the spraying distance angle, the push seat 7 can also be manually pushed, and the direction can be adjusted through the universal wheels 8. If more convenience is required, it can be adjusted to the required height through the hydraulic cylinder 3, and the telescopic column 61 expands and contracts to drive the crescent bracket 62 to slide and adjust the angle, making it more convenient for high-frequency adjustment.

[0029] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit and idea of the present utility model are within the protection scope of the present utility model.
