Description

Technical Field

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

[0002] A large amount of dust will be generated during the construction on site of a construction project. In order not to affect the normal construction of the construction workers, it is necessary to use spray-type dust reduction equipment. The water mist sprayed by the dust reduction device can play a role in dust reduction during the construction of the construction project. Most of the dust reduction devices currently used in construction sites use a barrel to atomize water, and then send the atomized water mist to a longer distance so that the water mist and dust condense and fall, thereby achieving a dust reduction effect. However, in order to improve work efficiency, multiple workers often carry out construction at the same time on the construction site, and dust often occurs over a large area. Most of the existing barrels do not have an adjustment mechanism, and most of them can only face in one direction. This results in the need to use multiple dust reduction devices on the construction site, and when workers change construction sites, they also need to adjust the direction of the dust reduction device, which is not convenient enough. Patent documents have been made to improve this.

[0003] For example, Chinese patent CN220176411U discloses a construction site dust suppression device, which relates to the field of dust suppression technology. The present application includes: a cart; a water tank, mounted on the top of the cart; and a mounting box, mounted on one side of the water tank, on which a tray is rotatably mounted. The present application adopts a rotatably mounted tray design. When the spur gear is driven to rotate by a driving member, the tray can be driven to rotate, so that the barrel can rotate along the axis of the tray, so that water mist can be sprayed on the circumference of the tray with the tray as the center of the circle, so that the sprayed water mist can cover multiple construction dust sections, and when the workers complete the construction and move to the construction site around the dust suppression device, there is no need to adjust the direction of the dust suppression device, which is more convenient and easy to use, and adopts a design of rotatably connecting the first connecting pipe and the second connecting pipe, so that when the tray rotates, the water supply pipeline formed by the first connecting pipe and the second connecting pipe will not bend and kink due to the rotation of the tray and the barrel, which is practical.

[0004] Although the above patent allows the barrel to rotate along the axis of the tray, so that water mist can be sprayed on the circumference of the tray with the tray as the center, so that the sprayed water mist can cover multiple construction dust areas, but in the process of spraying water mist, water droplets will remain on the inner wall of the barrel. The gathering of a large number of water droplets will produce backflow, causing water to easily flow back to the fan, affecting the normal use of the fan. Utility Model Content
