When the coupling assembly 24 is in the natural state, both ends of the first compression spring 245 abut against the first connecting plate 241 and the second connecting plate 244, so that the detachment prevention piece 243 abuts against the side wall of the first connecting plate 241 and the lower edge of the dust collection housing 23 is lower than the moving mechanism 5.
As shown in fig. 4, a plurality of mutually parallel ribs 12 are arranged on the metal roof at intervals, so that the strength of the roof is increased, and the metal roof is not easy to bend. In order to ensure the stability of the car body 11 moving on the metal roof, the car body 11 needs to be kept moving along the length direction of the convex rib 12 to reduce the jolt of the car body 11. When the vehicle body 11 is placed on a metal roof, the dust collection shell 23 first contacts with the convex rib 12, so that the sliding rod 242 and the first connecting plate 241 are driven to slide relative to each other, and the first compression spring 245 is elastically compressed, so that the lower edge of the dust collection shell 23 can be tightly attached to the upper surface of the convex rib 12.
However, when the dust collection shell 23 is attached to the upper surface of the rib 12, there is a gap between the dust collection shell 23 and the upper surface of the metal roof, so that fine sand is easily splashed from the gap when being sprayed from the sand-blasting nozzle 26, which causes environmental pollution. Therefore, the outer side wall of the dust collection shell 23 facing the advancing direction of the vehicle body 11 and the two side walls adjacent to the advancing direction of the vehicle body 11 are both provided with a dust blocking mechanism 6 for filling the gap between the dust collection shell 23 and the metal roof.

When the dust collection shell 23 is attached to the convex ridge 12 on the metal roof, the lower end of the shift rod 62 protrudes out of the lower edge of the dust collection shell 23, so that the shift rod 62 abutting against the convex ridge 12 slides upwards, and the rest of the shift rods 62 can make up for the rest of gaps between the lower edge of the dust collection shell 23 and the upper surface of the metal roof, and the diffusion space of fine sand is reduced.
In the process that the vehicle body 11 moves on the metal roof, the dust collection shell 23 abuts against the convex ridge 12 of the metal roof, and a plurality of gear columns make up most of gaps between the dust collection shell 23 and the metal roof, so that when the high-pressure pipe 22 provides high-pressure gas, fine sand in the high-pressure sand box 21 is driven to be uniformly sprayed out from each sand spraying nozzle 26, rust stains on the metal roof are removed, the fine sand is limited by the dust collection shell 23 and the dust blocking rod, the fine sand is gathered in the dust collection shell 23, and the scattering space of the fine sand is limited.
As shown in fig. 1 and 2, the dust suction mechanism 3 includes a dust collection box 31 fixed in the vehicle body 11, one side of the dust collection box 31 is connected with a dust suction pipe 32, the end of the dust suction pipe 32 is sealed, a plurality of dust suction nozzles 33 are connected to the circumferential surface of the dust suction pipe 32, the ports of the dust suction nozzles 33 are fixed to the outer side wall of the dust collection shell 23 away from the advancing direction of the vehicle body 11, the dust suction nozzles 33 are uniformly arranged along the width direction of the dust collection shell 23, and the dust suction nozzles 33 are communicated with the inner space of the dust collection shell 23.

And under the filtration of the filter cloth 36, the discharge of fine sand from the air outlet of the air pump 34 is reduced, and the stability of dust collection is ensured.
As shown in fig. 2 and 3, a sweeping brush assembly 7 is further disposed in the dust collection shell 23, the sweeping brush assembly 7 includes a bidirectional motor 71 fixedly connected in the dust collection shell 23, an axial direction of the bidirectional motor 71 is parallel to a width direction of the dust collection shell 23, and the bidirectional motor 71 is located at a port of the dust collection shell 23 and is disposed close to the dust collection nozzle 33; two output shafts of the bidirectional motor 71 are coaxially and fixedly connected with a rotating shaft 72, the other end of the rotating shaft 72 is rotatably connected with the inner wall of the dust collection shell 23, a plurality of bristles 73 are fixedly connected to the peripheral surface of each rotating shaft 72, the bristles 73 are spirally distributed along the length direction of the rotating shaft 72, and the spiral directions of the bristles 73 on the two rotating shafts 72 are opposite. Because the dust collection shell 23 contains more impurities, a shell 74 which wraps the bidirectional motor 71 is further arranged on the periphery of the bidirectional motor 71, so that the normal operation of the bidirectional motor 71 is guaranteed.
As shown in fig. 3, the brush 73 includes an extension portion 731 formed integrally with a hook portion 732 provided at an end portion of the extension portion 731, and an opening direction of the hook portion 732 is the same as a rotation direction of the bidirectional motor 71.
