Environment-friendly dust removal device for municipal road construction

The environment-friendly dust removal device for municipal road construction comprises a box body with a round hole formed in the front end, a wind cup set is installed at the top of the box body and comprises a rotating rod rotationally connected to the top of the box body, fixing plates are arranged on the outer wall of the rotating rod at equal intervals, and wind cup bodies are connected to one ends of the fixing plates; and a hollow plate is mounted at the rear end of the inner side of the box body. Concave hole open grooves are formed in the two sides of the wind cup body, so that no matter which direction a truck passes through the wind cup body, wind power can be generated to enable the wind cup body to rotate, in the moving process of the truck, the wind power borne by the wind cup body is gradually increased, and the rotating speed is gradually increased; after the truck penetrates through the box body, the wind cup body reaches the fastest rotating speed, then the suction fan assembly reaches the f
