Description

Technical Field

[0001] The utility model relates to the technical field of building spray dust reduction, in particular to a spray dust reduction device used in building construction sites. Background Art

[0002] Construction dust control refers to various measures taken during the construction process to reduce or control the generation and spread of dust in order to protect the environment, protect worker health, and improve construction efficiency. Construction generates a large amount of dust, which not only pollutes the environment but can also pose a threat to worker health, such as causing respiratory problems.

[0003] A Chinese patent with announcement number CN217855265U discloses a spray dust suppression device for construction sites. It cooperates with a water tank, a rotating mechanism and a spray dust suppression mechanism. The water tank and the spray dust suppression mechanism can be used to spray dust on the construction site. The rotating mechanism can be used to spray water mist at multiple angles when suppressing dust on the construction site. Compared with spraying water mist in one direction to suppress dust, the operation time can be effectively reduced, thereby greatly improving the dust suppression efficiency. Through the cooperation between the support cylinder and the track groove, the support circular plate can be supported while making its rotation more stable.

[0004] The above solution utilizes a rotating structure to achieve multi-location spraying of water mist by an atomizing nozzle. However, since the atomizing nozzle is in a fixed state, the spray angle is fixed during the rotation process, resulting in a single spraying range. In addition, there are cases where parts close to the water tank are not sprayed and dust is suppressed. To address this problem, we provide a spraying dust suppression device for construction sites.
