[0002] Construction is the process of turning things into physical objects at a designated location, which includes foundation construction, main structure construction, roof construction, decoration construction, etc. During the construction process, the movement of construction vehicles and the excavation of pit structures will lead to the generation of a large amount of dust and inhalable particulate matter. Long-term excessive inhalation of dust can easily lead to dust deposition in the lungs, causing pneumoconiosis, etc. The spread of smoke and dust will also harm the surrounding environment. In order to ensure the personal safety of personnel in the construction area and avoid the spread of smoke and dust, existing construction sites will be equipped with dust reduction devices.

Isolating and settling the smoke and dust through water mist is an important dust reduction protection measure for construction. Existing dust reduction devices are mostly fixed installation structures, and the direction of the nozzles is fixed and cannot be adjusted, so the flexibility of use is poor. In addition, the number and distribution spacing of the nozzles on the upper part of a single group of supports are fixed, and the spray volume cannot be controlled according to actual work needs, which can easily cause excessive spraying and lead to waste of water. Therefore, a dust reduction device for construction is proposed. Utility Model Content

When the atomizing nozzle 3 is installed in the nozzle mounting hole 11, the rubber sealing block 4 moves down and retracts under the resistance of the head seat at the bottom of the atomizing nozzle 3, so that the nozzle mounting hole 11 is opened and connected. The switch of the nozzle mounting hole 11 is synchronized with the installation of the atomizing nozzle 3, and the automatic switch control of the nozzle mounting hole 11 can be realized. When in use, the number and installation distribution of the atomizing nozzle 3 on the nozzle mounting seat 1 can be flexibly controlled according to the needs of use, so that the flexibility of use and the work applicability of the device are greatly improved.
