Description

Technical Field

[0001] The utility model relates to the technical field of spraying dust reduction, in particular to a spraying dust reduction device for a construction site. Background Art

[0002] During the construction process, construction sites will produce a large amount of general dust such as suspended particles and inhalable particles that are harmful to the atmosphere. These particles floating in the air will cause great harm to the health of construction workers. At the same time, they will also pollute the surrounding environment and have a huge impact on surrounding residents. Therefore, construction sites generally use spraying to reduce dust.

[0003] There are generally two common types of spray dust suppression. One is the spray pipe installed on the construction site wall, and the other is the fog cannon. Although the former has a wide coverage area, it needs to be laid, and it is troublesome to disassemble and assemble, inconvenient to move, and inflexible to use. Although the latter is easy to move, it has a small coverage area and is difficult to meet the dust suppression needs of a large area. Therefore, we propose a construction site spray dust suppression device. Utility Model Content
