Description

Technical Field

[0001] The present application relates to the technical field of dust reduction equipment, and more specifically, to a mobile dust reduction device for construction sites. Background Art

[0002] At construction sites, due to the frequent entry and exit of vehicles for digging and transporting earth, supplying materials, and removing construction waste, a large amount of dust is inevitably generated, causing serious pollution to the surrounding environment. In order to reduce the dust in the air, watering is usually used to reduce the dust content in the air.

[0003] The document with the prior art publication number CN211133394U provides a mobile dust reduction device for a construction site. The device is provided with bearings, a rotating shaft, a motor, a chain, a first gear and a second gear. In actual applications, the device itself can be automatically moved and easy to use, thereby achieving the purpose of convenient movement. By providing a nozzle, 360-degree dust reduction spraying can be carried out, and the water spraying covers a wide range, so that the device needs to be moved less times, reducing the labor intensity of workers and improving work efficiency. By providing a fixed rod, a movable rod, a top rod and a bolt, in actual applications, the height of the water spray of the device can be adjusted by the bolts, so that the device can carry out dust reduction at different heights, thereby increasing the practicality of the device.

[0004] Although the above-mentioned prior art solutions can achieve the relevant beneficial effects through the structure of the prior art, it is often not necessary to operate in multiple directions at the same time during the spraying operation, and the spraying direction needs to be switched during the operation. The above-mentioned device uses a fixed nozzle, which increases the difficulty of adjustment. In view of this, we propose a dust reduction device for construction sites that is easy to move.
