after the pit is repaired, the supporting seat 1 can drive the rolling column 28 to push and compact the repairing material at the pit when continuously moving forward, so that the repairing effect of the device on the road surface is improved, and meanwhile, the scraping plate 29 attached to the side wall of the rolling column 28 can scrape the residues adhered to the surface of the rolling column 28, so that the surface cleanliness of the rolling column 28 is greatly improved; through the arrangement of the scraper 29, after the scraper 29 scrapes the sundries on the rolling column 28, the sundries can fall on the upper surface of the scraper 29 and be collected in a centralized manner, so that the condition that the sundries on the rolling column 28 are directly fallen on the pit repairing part after being scraped by the scraper 29 to influence the road repairing quality is reduced; when the grinding column 28 drives the adsorption block 35 to move to a position close to the pressure block 31, the adsorption block 35 can attract the pressure block 31 and enable the pressure block 31 to slide towards the bottom end of the pressure chamber 30, when the grinding column 28 drives the adsorption block 35 to move away from the pressure block 31, the pressure block 31 moves upwards under the action of the elastic assembly 32 and presses the gas in the pressure chamber 30 to be sprayed out from the nozzle 33, so that the dust and impurities in the pits can be automatically cleaned, and the repairing quality of the road surface is further improved; when the grinding column 28 drives the adsorption block 35 to move to the end close to the pressure cavity 30, at this time, the adsorption block 35 is located at the outer end of the installation groove 34 and can effectively adsorb the pressure block 31, when the grinding column 28 drives the adsorption block 35 at this position to continuously rotate, at this time, the installation groove 34 is gradually inclined, so that the adsorption block 35 in the installation groove 34 can slide into the installation groove 34 and quickly keep away from the pressure block 31, the blocking effect of the adsorption block 35 on the resetting of the pressure block 31 is reduced, the pressure block 31 can be more effectively reset, the gas in the pressure cavity 30 is more effectively pressed out, and the cleaning effect of the nozzle 33 on pit impurities is improved; when the adsorption block 35 at the bottom of the grinding column 28 moves downwards, the adsorption block 35 at the top end of the grinding column 28 can be promoted to slide towards the inner end of the installation groove 34 more effectively by changing the change of the air pressure in the annular groove 37, so that the adsorption block 35 which rotates from the end of the pressure chamber 30 can be quickly away from the pressure block 31, the resetting effect of the pressure block 31 is further improved, and the air in the pressure chamber 30 can be sprayed out from the nozzle 33 more violently.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the utility model as defined by the appended claims. The scope of the utility model is defined by the appended claims and equivalents thereof.
