[0033] Referring to Figure 4 and Figure 5 As shown, in the embodiment: the threads on the surface of the threaded rod 402 are symmetrically distributed; the transmission gears 403 are engaged with each other through the tooth grooves; the transmission bevel gears 401 and the connecting bevel gears 405 are engaged with each other through the bevel tooth grooves; the inside of the fixed frame 1011 is provided with a horizontal sliding groove matched with the connecting rod 404, and located between the cleaning scraper 201 and the protection scraper 202; the symmetric distribution of the threads on the surface of the threaded rod 402 facilitates the rotation of the threaded rod 402 to drive the two connecting rods 404 to approach or move away from each other; and the rotation of one threaded rod 402 can drive the rotation of the other threaded rod 402 through the transmission gears 403.

[0034] Working principle: the user installs the waste collecting box 3 on the fixed frame 1011, and then starts the road roller main body 1 to make the road roller main body 1 perform compaction work, and starts the servo motor 4, which drives the transmission bevel gears 401 to rotate, so that the rotation of the transmission bevel gears 401 drives the rotation of the threaded rods 402, the rotation of the threaded rods 402 drives the rotation of the transmission gears 403, the rotation of the transmission gears 403 drives the rotation of the other threaded rods 402 through the engagement of the transmission gears 403, and the rotation of the threaded rods 402 drives the horizontal sliding of the connecting rods 404 in the fixed frame 1011.

[0035] The surface of the compression wheel 1012 is adhered with sundries, and then is in contact with the surface of the cleaning scraper 201, the cleaning scraper 201 scrapes off the sundries adhered to the surface of the compression wheel 1012, meanwhile, the end face of the protective scraper 202 is longer than the cleaning scraper 201, and the gap between the protective scraper 202, the cleaning scraper 201 and the surface of the compression wheel 1012 is inconsistent, so that the protective scraper 202 can shield the sundries cleaned by the cleaning scraper 201, and avoid the sundries from splashing and falling to the road surface, and the sundries can stay in the space between the protective scraper 202 and the cleaning scraper 201, and roll from the protective scraper 202 and the cleaning scraper 201 to the inside of the fixed frame 1011 through the inclined slope of the protective scraper 202 and the cleaning scraper 201, and then fall into the waste collecting box 3 through the discharging opening in the fixed frame 1011 to be recycled, so that the sundries are avoided from falling to the road surface and being adhered by the compression wheel 1012 again.

[0036] The surface of the connecting rod 404 is provided with the pushing scraper 407 which is in close contact with the surfaces of the protective scraper 202 and the cleaning scraper 201 under the extension and retraction of the extension spring 408, and the position of the pushing scraper 407 at the end of the connecting rod 404 is adjusted by the electric telescopic rod, when the connecting rod 404 drives the pushing scraper 407 to slide from the center position of the cleaning scraper 201 and the protective scraper 202 to the two ends, the electric telescopic rod is retracted to drive the connecting rod 404 to move the pushing scraper 407 to the close contact position of the cleaning scraper 201, the protective scraper 202 and the compression wheel 1012, so that the pushing scraper 407 scrapes off the sundries on the surfaces of the cleaning scraper 201 and the protective scraper 202, and pushes the cleaned sundries to the inside of the fixed frame 1011 and then to the inside of the waste collecting box 3 for collection, and when the connecting rod 404 drives the pushing scraper 407 to slide from the two ends of the cleaning scraper 201 and the protective scraper 202 to the center position, the electric telescopic rod is extended to drive the connecting rod 404 to move the pushing scraper 407 to close to the inner wall of the fixed frame 1011, so that the sundries between the cleaning scraper 201 and the protective scraper 202 are accumulated at the center of the cleaning scraper 201 and the protective scraper 202 under the mutual pushing of the pushing scrapers 407.

[0037] The technical scope of the utility model is not limited to the above-mentioned content, and the above-mentioned embodiment can be variously deformed and modified by the person skilled in the art without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the protection scope of the utility model.
