[0002] Gardening and greening projects are projects for building landscape gardens and green spaces. Gardening and greening provides people with a good place to rest, culturally entertain, get close to nature, and satisfy people's desire to return to nature. It is an important measure to protect the ecological environment and improve the urban living environment. Gardening and greening generally refers to environmental construction projects in gardens, urban green spaces, and scenic spots, including garden construction projects, earthwork projects, garden mountain construction projects, garden water management projects, garden paving projects, greening projects, flower planting projects, etc. Dust suppression fog cannons are often used in gardening and greening projects to prevent dust.

[0003] The prior art dust prevention device for landscaping projects - dust reduction fog cannon uses a fan to blow atomized water out of the wind pipe to spray dust on the surrounding environment. However, in actual use, the high power and long-distance spray of the fan cause the water flow to form an atomized water column and spray to a distance, while ignoring the spraying area near the wind pipe, forming a spraying dead angle, making the dust prevention and dust reduction effect in this area poor, causing dust to adhere to the surface of the wind pipe, or be sucked into the fan for a long time, causing the inner wall of the wind pipe to be polluted. Utility Model Content

[0004] The utility model aims to provide a dust prevention device for landscaping projects.
