Background

In construction scenes such as buildings, road construction, mining and the like, a large amount of dust can be generated in construction activities. The dust emission not only can reduce the air quality of a construction area and the surrounding area, and seriously threatens the health of a respiratory system of on-site operation personnel, but also can be spread to surrounding residential areas and business areas, so that the environmental problems of haze, visibility reduction and the like are caused, the requirements of the current environment-friendly construction are not met, and the dust emission is strictly controlled by an environment-friendly supervision department.

In order to control construction dust, fog gun devices are widely used as core dust settling equipment in the industry at present. The conventional fog gun device generally consists of a fixed base, a fog gun barrel and a simple angle adjusting structure, and has limitations in the use process.

The traditional fog gun device has a rotary spraying function with a fixed height, or can realize small-range pitching angle adjustment through a single mechanism, and can not realize the composite motion of rotation and up-down swing at the same time. For example, when facing dust scattered in a large area and low altitude, the fog gun is required to swing up and down while rotating to expand the spray coverage, and when facing dust concentrated locally and not needing to swing in a large range, the fog gun is required to only keep rotating for spraying. The traditional device can not switch operation modes according to the dust spreading characteristics, so that spraying coverage is incomplete in part of scenes.
