Preferably, the two ends of the interior of the dust-cleaning cover are provided with 30mm angle steels serving as frameworks to support the dust-cleaning cover, the side faces of the dust-cleaning cover are formed by mutually connecting and splicing sheet-shaped thin iron plates through hinges, the thin iron plates at the end parts are fixed on the frameworks at the edge positions, the connecting holes are formed in the thin iron plates at the end parts, and the dust-cleaning cover is in a closed state except the dust-collecting holes and the connecting ports.
Preferably, the movable trolley is provided with a height-adjusting rod, the front end and the rear end of the dust-purifying cover are arranged on the height-adjusting rod, and the fixed position of the dust-purifying cover on the height-adjusting rod is adjustable.
Preferably, the thin iron plate on the side surface of the end part of the dust cleaning cover is provided with a hook, the heightening rod is provided with a hanging hole, and the hook on the dust cleaning cover is hung on the hanging hole.
Preferably, the dust removing hole is arranged on one side surface of the dust cleaning cover, and the side surface is close to the roadway wall in the guniting state.
The invention has the advantages that: the device is convenient to transport and move, can arrange the dust suction port on the spot of the guniting working surface at any time, has simple and light operation, saves time and labor,
the dust cleaning cover structure is provided with the dust suction port, the sucked field wind power is uniform, the dust removal efficiency is good, and the dust fall rate is improved by more than 60% compared with the prior art. The dust-cleaning cover is connected by local foldable hinges, can be folded after being used, is convenient to be folded and unfolded together with the spiral air duct, and cannot be stored inconveniently due to large volume.

Detailed Description
The invention relates to a dust removal device for a guniting construction site, which has a structure shown in figure 1. The dust removal fan of the device comprises a flat car, the flat car can move on the rail, and the dust removal fan can move conveniently. The spiral air duct can be folded, and the length of the spiral air duct can be adjusted by adjusting the folding of the spiral air duct.
Specifically, see, including dust exhausting fan, dust exhausting fan sets up on the flatbed, and the flatbed is marchd on the track of coal mine tunnel bottom, still includes can axial folding spiral dryer and clean dirt cover, and the connecting hole connection spiral dryer is established to the rear portion of clean dirt cover, and open on the surface of clean dirt cover has the dust absorption hole, and clean dirt cover sets up on a movable shallow, and the movable shallow removes in the track both sides. The dust cleaning cover is of a rectangular three-dimensional structure, the dust suction hole is formed in one side face of the dust cleaning cover, and the side face is close to the roadway wall in the guniting state.
