Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a building construction spraying device. Background Technology

[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. It includes foundation construction, main structure construction, roof construction, decoration construction, etc. Construction generates a lot of dust, so spraying devices are needed for dust suppression.

[0003] Chinese patent discloses a construction dust suppression spraying device (authorization announcement number CN221557903U). This patented technology uses a water pump to pump water from a bucket into a vertical rod through an inlet pipe, then into a guide pipe via a diverter block, and finally sprays it out in an atomized state at the nozzle, thus providing dust suppression for the construction site. Moreover, this structure only needs to be fixed to the ground during use, saving labor and achieving high dust suppression efficiency. However, the aforementioned construction dust suppression spraying device relies entirely on the water pressure of the pump for water spraying, resulting in relatively weak water spray force, which is detrimental to the spraying range. The water droplets sprayed from the nozzle are relatively large, affecting the dryness of the work area. The water mist has low fineness and low uniformity, which is not conducive to dust suppression. Therefore, those skilled in the art have provided a construction spraying device to solve the problems mentioned in the background art. Utility Model Content
