Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression spraying equipment, in particular to dust suppression spraying equipment for road construction. Background Art

[0002] At present, during the construction of common urban roads, bridges and other projects, spray equipment is needed to spray dust reduction and dust suppression to improve the environmental protection of road construction and reduce the phenomenon of large-scale dust pollution. At present, a Chinese patent with a publication number of CN219930819U discloses a municipal road construction dust suppression spray equipment, including a base plate, a water tank is fixedly connected to the top of the base plate, a liquid pump is fixedly connected to the top outer wall of the water tank, the liquid pumping end of the liquid pump is located in the water tank, and an adjustment mechanism is arranged on one side of the top of the base plate. When it is used, the liquid pump is started, and the liquid pump can pump out the water in the water tank and transport it to the water storage box through a water hose. Due to the effect of water pressure, the water in the water storage box can be sprayed out of the atomization holes on three sides, which can greatly increase the spraying area. The fan is started, and the fan can blow the mist water, which can increase the moving distance of the water in the air, and can make more dust be adsorbed. Therefore, the effect of greatly increasing the area of ​​the dust reduction area can be achieved, thereby reducing the pushing distance of the staff.

[0003] The above technology discloses a municipal road construction dust suppression spray equipment, which draws water through a liquid pump and pumps it into a water storage box, and uses atomization holes set on three sides of the water storage box to spray and reduce dust over a large area. However, it has the following shortcomings when used in road construction: 1. The dust suppression width cannot be accurately and flexibly adjusted according to the width of the construction road surface. When there are residents and people on both sides of the road, water sprayed directly on both sides over a large area is likely to affect the normal lives of the people and residents, especially when the weather is cooler, which will cause greater confusion to roadside personnel. When used in such an environment, the flexibility of use is not ideal. In view of this, we propose a road construction dust suppression spray equipment to solve the above problems.
