Dustproof diffusion device for building construction

Abstract

The application discloses a dustproof diffusion device for building construction and relates to the technical field of building machinery, which comprises a rack, a pollution guiding box, a dust catching net, a water conveying mechanism and a vibrating mechanism. When the dustproof diffusion device is used, water flowing in a water pipe pushes driving blades to rotate, drives a cam to rotate, acts on the dust catching net, and makes the dust catching net vibrate under the elastic force of spring one and spring two, so that the mixture blocked in the mesh of the dust catching net is shaken off and falls into the pollution guiding box. While the dust catching net vibrates, the pollution guiding box below is vibrated up and down, so that the mixture attached in the pollution guiding box is shaken off and flows to a sewage channel or a sewage tank along with sewage, thereby avoiding the phenomenon that the pollution guiding box is inconvenient to clean the internal accumulated matters due to the shielding of the dust catching net.
