Tunnel inner contour dust cleaning system

The invention belongs to the technical field of tunnel dust cleaning, and relates to a tunnel inner contour dust cleaning system. The tunnel inner contour dust cleaning system comprises a box body, a box cover is movably connected to the upper end of the interior of the box body through a hinge, a dust collector is arranged in the box cover, a cavity is formed in the box body, an air inlet pipeline is arranged in the cavity, the upper end of the air inlet pipeline is fixedly connected with the dust collector, electric push rods are fixedly connected to the surfaces of the box cover and the box body, and the electric push rods are annularly and evenly arranged on the surfaces of the box cover and the box body. The tunnel inner contour dust cleaning system has the beneficial effects that dust in a tunnel can be fed into the air inlet pipeline through the dust collector under the use of an elastic pipeline and a dust collection plate and is filtered in the cavity, gas obtained after gas dust with dust is precipi
