Description

Technical Field

[0001] The utility model belongs to the technical field of construction dust removal, and in particular relates to a dust prevention device for municipal road construction. Background Art

[0002] Dust removal is a technical measure to remove particulate matter from dusty gases to improve air pollution in the surrounding environment. During municipal road construction, fog cannons are generally used to remove dust from the construction site. The fog cannon device moves through the moving wheels set at the bottom. When the device is in use, it is supported by the moving wheels, which makes the device unstable during operation and easy to move, resulting in changes in the direction of the water mist spraying. The movement of the device is also easy to cause harm to the on-site workers. Utility Model Content

Therefore, when in use, the construction site can be effectively dusted by changing the direction of the fog cannon barrel.

[0014] The base is equipped with a controller, and the blower, the water pump, the motor and the electric telescopic rod are all electrically connected to the controller.

[0015] The electrical components of the device are uniformly controlled through the controller. When in use, the fog cannon barrel can be kept in continuous motion to increase the spraying area of ​​the water mist, thereby achieving a better dust reduction and removal effect.

[0016] A push handle is provided at the rear side of the base, which is used to facilitate construction workers to push the device to move.
