The dust suction pipe 304 is located inside the protective cover 201 and moves with the purge pipe 202. The dust suction pipe 304 is fixedly installed on the movable plate 206. The dust suction pipe 304 is a hose that can adapt to the movement of the movable plate 206. The dust suction pipe 304 is connected to a dust hood 305. The dust hood There are multiple 305s, one of which is close to the ground to absorb the dust blown out of the crack in time. Some of the dust hoods 305 are installed on the side of the second dust pipe 304 to absorb the dust raised in the protective cover 201, reducing the impact of dust on the filling of the repair material. The air outlet of the vacuum pump 302 is connected to the collection box 301, and the garbage and dust generated by cleaning and blowing are sucked into the interior of the collection box 301 for collection, reducing pollution to the environment. In order to prevent dust from entering the interior of the vacuum pump 302 and causing damage to it, a dust filter 306 is installed inside the collection box 301. The vacuum pump 302 and the collection box 301 are connected. The connection position is located inside the dust filter 306, and air is sucked into the collection box 301 through the vacuum pump 302, and then the air is sucked into the cleaning box 101 through the dust suction pipe 1 303, and the air is sucked into the protective cover 201 through the dust suction pipe 2 304 and the dust suction cover 305, and the dust and garbage generated by the brush 104 and the dust blown out from the crack by the purge pipe 202 are absorbed, and the dust and garbage are sucked into the collection box 301 for collection, and the dust and garbage are blocked by the dust filter 306 to prevent the dust and garbage from being sucked into the vacuum pump 302 and causing damage to the vacuum pump 302. A cleaning port is provided, and a cleaning plate is detachably connected to the cleaning port. The cleaning plate can be opened regularly to clean out the garbage and dust inside the collection box 301. It should be noted that the cleaning shaft 102 rotates forward to sweep the dust and garbage backwards. The dust suction pipe 1 303 is connected to the rear side of the cleaning box 101, which is convenient for sucking the cleaned dust into the collection box 301 in time. The cleaning shaft 102 drives the brush 104 to rotate forward, which also facilitates the forward movement of the vehicle body 1. The air outlet of the purge pipe 202 is bent toward the dust suction pipe 2 304. When blowing inside the crack, it is convenient to blow the dust into the dust suction pipe 2 304 and be absorbed into the interior of the collection box 301.

[0049] In step (d), the repair device includes a storage barrel 401 and a feeding pump 402. The storage barrel 401 is installed on the vehicle body 1. The interior of the storage barrel 401 contains a repair material, which can be hot asphalt. The storage barrel 401 can heat and stir the repair material. The feed port of the feeding pump 402 is connected to the storage barrel 401, and the discharge port of the feeding pump 402 is connected to the feeding pipe 403. The feeding pipe 403 is located inside the protective cover 201 and moves with the purge pipe 202. The feeding pipe 403 is fixedly installed on the movable plate 206. The purge pipe 202 and the dust collection cover 305 first process the dust in the crack, and then fill the repair material through the feeding pipe 403. The repair material is transported to the feeding pipe 403 by the feeding pump 402. The crack is filled with repair material through the feeding pipe 403. The camera is installed inside the protective cover 201. The camera takes an image of the crack and transmits it to the processor. A lighting lamp can be installed inside the protective cover 201 to ensure the clarity of the shooting. The processor recognizes the image, that is, recognizes the trajectory of the crack, formulates a suitable walking route, controls the electric cylinder 203 and the screw feeding mechanism 204 to drive the movable plate 206 to move, so that the purge pipe 202 first purges the crack, and then the feeding pipe 403 fills the cleaned crack with repair material. During the filling process, the camera can also monitor the filling situation. When the repair material is filled to the road surface, the processor controls the movable plate 206 to continue moving, and the subsequent cracks can be repaired.

[0050] like Figure 1 and Figure 8As shown, in step (e), the cooling and solidifying device includes a flattening roller 501 and a cold air pipe 502, the flattening roller 501 is rotatably connected to the rear side of the vehicle body 1, a cold water chamber is opened inside the flattening roller 501, a chiller 503 is installed on the vehicle body 1, the chiller 503 is connected to the cold water chamber, the chiller 503 is connected to a water inlet pipe 504 and a water outlet pipe 505, the flattening roller 501 is rotatably connected to the rear side of the vehicle body 1 through a rotating shaft 506, the rotating shaft 506 is fixedly connected to the rear side of the vehicle body 1, the flattening roller 501 is rotatably connected to the rotating shaft 506, the rotating shaft 506 is a hollow structure and is rotatably connected to the cold water chamber, the water inlet pipe 504 and the water outlet pipe 505 are respectively connected to the rotating shaft 506 on both sides of the flattening roller 501. The cold water is produced by the chiller 503 and transported to the inside of the cold water chamber to cool the flattening roller 501. As the vehicle body 1 moves, the flattening roller 501 rotates forward to roll the filled repair material, so that the repair material can fill the crack as quickly as possible. At the same time, the cold water cools the flattening roller 501. The flattening roller 501 cools the repair material during the rolling process, accelerates its solidification, and the surface of the flattening roller 501 is in a low temperature state, which is convenient for reducing the adhesion of the repair material. The cooling pipe 502 passes through the cooling pipe 507 The cooling pipe 507 is connected to the purge pipe 202, and the cooling pipe 507 is located inside the cold water chamber. The two ends of the cooling pipe 507 pass through the rotating shaft 506 and are connected to the air supply device 207 and the cooling pipe 502 respectively. The cooling pipe 502 is used to spray gas to the repaired cracks. The cooling pipe 507 is spirally arranged inside the cold water chamber to increase the heat exchange area between cold water and air and improve the cooling effect on the air. The air supply device 207 supplies air to the purge pipe 202 and at the same time supplies air to the cooling pipe 502 through the cooling pipe 507. When the air enters the cooling pipe 507, the air in the cooling pipe 507 is cooled by the cold water. Cooling: Blow air toward the contact position between the flattening roller 501 and the road surface through the cold air pipe 502 to assist in the cooling and solidification of the repair material. At the same time, the flattening roller 501 and the road surface are swept to reduce the adhesion of the repair material on the flattening roller 501 and reduce the adhesion of dust and impurities on the surface of the repair material to ensure the repair effect. The flattening roller 501 moves with the vehicle body 1 to flatten the repaired repair material to promote the filling of the crack by the repair material. At the same time, the flattening roller 501 is cooled by cold water, thereby cooling the repair material. The repair material is further cooled by the cold air pipe 502 to accelerate the cooling and solidification of the repair material.

[0051] like Figures 1 to 3 and Figure 7As shown, in order to reduce the secondary pollution caused by the dust in the collection box 301, a water tank 2 and a water pump 3 are installed on the vehicle body 1. The water pump 3 is connected to the water tank 2, and the water outlet of the water pump 3 is connected to the spray pipe 4. The spray pipe 4 is located at the top of the collection box 301 and is used to spray clean water into the interior of the collection box 301. The water in the water tank 2 is sent into the spray pipe 4 through the water pump 3. Clean water is sprayed into the interior of the collection box 301 through the spray pipe 4. The clean water absorbs the dust and reduces the escape of dust. The dust increases in weight after being stained with water, which prevents the dust from being raised.

The bottom of the collection box 301 is connected to a drain pipe, and a valve is installed on the drain pipe. The valve is opened regularly to discharge the water in the collection box 301 in time to avoid the water level being higher than the connection between the vacuum pump 302 and the collection box 301 so that water enters the vacuum pump 302, and clean water is added to the inside of the water tank 2 regularly.

[0052] In order to reduce the escape of dust during the cleaning and blowing process, a plurality of protective sheets 5 are fixedly connected to the bottom of the cleaning box 101 and the protective cover 201. The protective sheets 5 are made of soft material such as rubber. The bottom of the cleaning box 101 and the protective cover 201 are shielded by the protective sheets 5 to prevent the cleaning box 101 and the protective cover 201 from colliding with the road surface due to uneven road surface when the vehicle body 1 is moving. At the same time, the protective sheets 5 block the dust to prevent the escape of dust from polluting the surrounding environment, and at the same time prevent the dust from hindering the subsequent crack filling, and deal with the dust in time.
