[0001] The utility model belongs to the field of dust suppression devices, and in particular relates to a dust suppression device for house construction. Background Art

[0002] With the acceleration of urbanization and the continuous expansion of the scale of housing construction, the dust pollution problem generated at construction sites is becoming increasingly serious. During the construction process, earth excavation, material transportation, concrete mixing and other links will generate a large amount of dust, which not only affects the health of construction workers, but also causes pollution to the surrounding atmospheric environment and triggers ecological problems such as haze.

However, sprinkler trucks are huge in size and can only spray water on the ground when spraying. The coverage range is limited, making it difficult to suppress dust diffused in the air, and it is not convenient to reuse the water droplets that are not atomized at the nozzle. Further improvement is needed. Utility Model Content

[0018] Beneficial effects of the utility model:

[0019] 1. By setting up a drive mechanism, the third motor in the drive mechanism drives the third gear to rotate, meshing with the gear ring, thereby causing the rotating body in the first spray assembly to rotate on the limiting cylinder. The first nozzles evenly distributed on the side walls of the rotating body rotate accordingly, spraying water to a wider range of space and ground areas. At the same time, the axial flow fan in the second spray assembly is started, and the airflow generated pushes the water mist sprayed by the second nozzle in the elbow to spread far away. The combination of the two significantly increases the coverage area of dust reduction, solving the problem of limited coverage of traditional sprinkler trucks;

[0020] 2. During the rotation of the first spray assembly, multiple first nozzles spray water mist into the air from different angles, which can capture and settle the dust suspended in the air. The airflow generated by the axial flow fan drives the water mist sprayed by the second nozzle to form a water mist flow with a certain impact force, which actively contacts the dust suspended in the air, thereby enhancing the dust treatment capacity in the air and making up for the deficiency of traditional methods in settling dust diffused in the air.

[0021] 3. A filter plate is provided in the placement slot at one end of the fixed frame. The un-atomized water droplets at the first nozzle will drip downward through the water flow slot and then flow into the return water tank through the filter plate. The return water tank opening is designed to facilitate water collection. The water pump in the pumping mechanism extracts the water filtered by the filter plate from the return water tank and transports it to the first spray assembly and the second spray assembly through a pipeline for reuse in dust reduction, thus forming a water resource recycling method. This solves the problem of serious waste caused by the lack of water resource recycling function in traditional dust reduction methods.

[0022] 4. In the moving mechanism, the first motor drives the second gear to rotate, and through engagement with the first gear, the second roller on the connecting frame rotates, cooperating with the first roller at the lower end of the bracket, so as to facilitate the flexible movement of the dust suppression device at the construction site. The second motor in the diffusion assembly drives the rotating rod to rotate, and the plate on the rotating rod rotates accordingly, which can form wind force to drive out the water mist sprayed downward by the second nozzle, thereby achieving a greater degree of diffusion of the water mist.

[0042] See also Figure 1 and Figure 8 In this embodiment, the driving mechanism includes a third motor 11, a third gear 12 and a gear ring 13; the inner wall of the fixed frame 1 is fixedly connected to a frame, the third motor 11 is fixedly connected to the frame, the upper end of the output shaft of the third motor 11 is fixedly connected to the third gear 12, the side wall of the rotating body 41 is fixedly connected to the gear ring 13, the gear ring 13 and the third gear 12 are engaged with each other, and the third motor 11 is turned on to rotate the third gear 12.

[0043] See also Figure 1 In this embodiment, the upper end of the return water tank 2 is open, and the first spray assembly 4 is located directly above the return water tank 2 to facilitate unused water to fall into the return water tank 2.

[0044] See also Figure 1 、 Figure 3 and Figure 4 In this embodiment, a moving mechanism 5 is provided at both ends of the fixed frame 1, and the moving mechanism 5 includes a bracket 51 and a first roller 52; both ends of the fixed frame 1 are fixedly connected to the bracket 51, and the lower end of the bracket 51 is fixedly connected to two first rollers 52.

[0047] Working principle: First, the third motor 11 in the driving mechanism is turned on, and its output shaft drives the third gear 12 to rotate. Since the third gear 12 and the gear ring 13 on the side wall of the rotating body 41 in the first spray assembly 4 are engaged with each other, the rotating body 41 is driven to rotate at the upper end of the limiting cylinder 3, so that the first spray heads 42 evenly distributed on the side wall of the rotating body 41 rotate at multiple angles;

[0051] The other part forms water drops and falls into the water tank 81. The user can place a rag inside the water tank 81 to absorb the water inside the water tank 81 to save water.

The second gear 57 engages with the first gear 56 at one end of the second roller 55 to drive the second roller 55 to rotate, and cooperates with the first roller 52 at the lower end of the bracket 51, so that the device can be easily moved at the construction site.
