Dust falling device for garden engineering

The dust falling device comprises a moving box and a dust falling cylinder, idler wheels are movably installed at the positions, close to the four corners, of the lower surface of the moving box, a control box is fixedly installed on the surface of one side of the moving box, and adjusting rods are fixedly installed at the positions, close to the two sides, of the upper surface of the moving box; a dust falling cylinder is arranged above the moving box, an annular water pipe is fixedly installed on the front end face of the dust falling cylinder, and a multifunctional supporting rod is arranged on the portion, close to the rear end, of the upper surface of the moving box. According to the dust falling device for garden engineering, when the dust falling device is not used, the dust falling cylinder can be stored in the moving box, so that the occupied space can be reduced when the dust falling device is parked, and when the dust falling cylinder is bumped, the multifunctional supporting rod can effectively bu
