Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a spray dust reduction device for an excavator. Background Art

[0002] An excavator is an earth-moving machine that uses a bucket to dig materials above or below the supporting surface and load them into transport vehicles or unload them to stockpiles. The materials excavated by the excavator are mainly soil, coal, silt, and pre-loosened soil and rocks. Excavators are widely used in construction.

[0003] During the construction process, excavator construction is often accompanied by a large amount of dust. In order to meet the requirements of green construction and reduce the on-site dust index, the traditional dust reduction method is to arrange spraying or fog cannon dust reduction machines along the construction site fences. However, as the construction progresses and the working surface gradually advances, the fence spraying is unable to reduce the dust in the site. Due to the limitations of water and power supply, fog cannons can only be arranged at fixed points in flat positions and cannot reduce dust in some locations deep in the dead corners of soil piles. The movable small fog cannon vehicles are often converted from electric tricycles, which poses a great safety hazard and is not suitable for use in earthwork sites where large machinery passes through, especially in construction sites with high safety and civilization requirements.
