The lifting operation can be flexibly adjusted to adapt to the cleaning requirements of different heights;

[0034] The cleaning component consists of a scraping part and a pressing part. The scraping part includes: two rotating blocks 5. The two rotating blocks 5 are respectively located on both sides of the bottom surface of the mounting frame 1. A rotatable rotating threaded rod 6 is arranged between the bottom surfaces of the two rotating blocks 5. A movable cleaning table 9 is sleeved on the surface of the rotating threaded rod 6;

[0035] The pressing part includes: a heating box 14. One side surface of the heating box 14 is fixedly connected to one side surface of the movable cleaning table 9. Meshing holes 22 matching with the rotating threaded rod 6 are respectively opened at the centers of the heating box 14 and the movable cleaning table 9.

[0036] The scraping component further includes: a side cleaning strip 12, which is fixedly installed on the upper surface of the movable cleaning table 9. A storage groove 18 and a placement groove 19 are also formed on the top surface of the movable cleaning table 9. A storage battery 15 is arranged at the center of the placement groove 19. A power cable is connected to the side surface of the storage battery 15. The storage battery 15 is connected to the heating box 14 through the power cable. A bottom cleaning strip 23 is also arranged at the center of the movable cleaning table 9. The bottom cleaning strip 23 is located at the center of the storage groove 18. A leak-proof plate 20 for receiving the shoveled asphalt is also arranged on the upper surface of the storage groove 18. One end of the rotating threaded rod 6 is provided with a driving motor 7. Collar rings are arranged at both ends of the rotating threaded rod 6. Touch buttons 13 capable of controlling the rotation direction of the driving motor 7 are arranged on the upper surfaces of the two collar rings;

[0037] The driving motor 7 drives the rotating threaded rod 6 to rotate. Through the thread action, the movable cleaning table 9 makes a reciprocating motion under the scraper body 3. The side cleaning strip 12 and the bottom cleaning strip 23 move along with the movable cleaning table 9 to scrape and clean the residues on both sides of the scraper body 3 that are prone to sticking asphalt.

The lifting operation can be flexibly adjusted to adapt to the cleaning requirements at different heights;

[0044] The staff controls the dual-axis motor 4 to drive the two connecting rods 8 to rotate through signals, thereby driving the rotating blocks 5 to perform rotational movements on both sides of the scraping plate body 3, so as to quickly turn out the cleaning assembly for use during the cleaning work. The scraping plate body 3 is connected to the mounting frame 1 through the fixed rods 24 on both sides, so as to maintain stability when the rotating block 5 drives the working mechanism to rotate and store, provide stable support. The limiting plate 10 is used to limit the moving range of the working mechanism, ensuring that the working mechanism maintains an accurate rotational position when storing and turning out for use;

[0045] The driving motor 7 drives the rotating threaded rod 6 to rotate. Through the thread action, the movable cleaning table 9 makes a reciprocating movement below the scraping plate body 3. The side cleaning strips 12 and the bottom cleaning strip 23 move along with the movable cleaning table 9 to scrape and clean the residues on both sides of the scraping plate body 3 that are more likely to stick with asphalt;

[0046] The storage battery 15 provides electrical energy for the heating box 14. The heating elements in the heating box 14 heat the vertical heating roller 16 and the horizontal heating roller 17. The vertical heating roller 16 and the horizontal heating roller 17 roll along with the movement of the movable cleaning table 9 to heat and press the asphalt on the surface of the scraping plate body 3, improving the cleaning effect. The heating rollers have strong thermal conductivity and can quickly transfer heat to the scraping plate body 3 to soften the residual asphalt, achieving the effect of facilitating cleaning;

[0047] The bottom cleaning bar 23 works in the storage groove 18, and the scraped asphalt is collected by the leak-proof plate 20 to avoid polluting the working environment. The touch button 13 is used to contact the rotating threaded rod 6 after the movable cleaning table 9 reaches one side of it, so as to change the rotation direction of the driving motor 7 and realize the bidirectional movement of the movable cleaning table 9.
