The motor drives one of the sprocket wheels 901 to rotate, and cooperates with the transmission function of the chain belt 906 to drive the other sprocket wheel 901 and the sprocket wheel 905 to rotate.

[0057] The working principle of the present invention is:

[0058] When in use, the motor drives one of the sprockets 1 901 to rotate, and cooperates with the transmission function of the chain belt 906 to drive the other sprocket 1 901 and the sprocket 2 905 to rotate, so that the two sets of rotating shafts 2 804 rotate synchronously;

[0059] The assembly of the second rotating shaft 804 and the second convex strip 806 rotates, driving the assembly of the sleeve 807 and the second cleaning plate 809 to rotate synchronously, and in this process, the sliding column 814 slides along the upper arc groove 811, the lower arc groove 812 and the inclined groove 813. When the sliding column 814 slides along the lower arc groove 812, the second cleaning plate 809 sticks to the ground and sweeps the dust toward the connecting port 604; then the sliding column 814 slides along one of the inclined grooves 813, so that the assembly of the second cleaning plate 809 and the sleeve 807 rotates and moves upward, so that the second cleaning plate 809 is away from the ground; then when the sliding column 814 slides along the upper arc groove 811 and the other inclined groove 813, the second cleaning plate 809 is always above the ground to avoid sweeping dust outward;

[0060] During the rotation of the sprocket wheel 2 905, the rotating tube 902 drives the assembly of the rotating shaft 1 407 and the convex strip 1 408 to rotate, thereby driving the assembly of the upper rotating disk 404 and the lower rotating disk 401 to rotate, and the assembly of the column 411 and the reinforcement ring 412 to rotate synchronously, driving the assembly of the mounting ring 501, the inclined plate 502 and the cleaning plate 1 503 to rotate, and the cleaning plate 1 503 moves along the circular path to clean the ground and gather the dust to the middle;

[0061] During the rotation of the second rotating shaft 804, the impeller 805 is driven to rotate, so that the air inside the dust collecting tank 701 passes through the second connecting pipe 705 and the air inlet pipe 802 into the interior of the air cylinder 801, and then is discharged from the exhaust pipe 803; the interior of the dust collecting tank 701 is in a negative pressure state, so that the air and dust at the bottom of the housing 100 pass through the air inlet 410 into the interior of the sealing cover 300, and then enter the interior of the dust collecting tank 701 through the connecting pipe 1 702, and then through the filtering effect of the filter screen 703 and the filter cotton 704, the dust is accumulated in the dust collecting tank 701; and the air discharged from the filter screen 703 enters the interior of the L-shaped bellows 815, and then blows the air to the connecting port 604 through the inclined blowing slot 816, so that the dust moves to the bottom of the lower turntable 401;

[0062] The output end of the cylinder 414 is extended, driving the annular slide rail 413 to move downward, thereby driving the assembly of the reinforcement ring 412, the column 411 and the lower turntable 401 to move downward, so that the scraper 403 is in contact with the ground, and as the lower turntable 401 moves downward, the spring 405 is squeezed and contracted, and then the elasticity of the spring 405 ensures that the scraper 403 is in close contact with the ground while preventing the scraper 403 from hitting the ground too hard and damaging the ground; then the assembly of the lower turntable 401 and the upper turntable 404 rotates with the rotating shaft 407, so that the scraper 403 is in contact with the ground and scrapes off the chewing gum and the like attached to the ground, and the scraped chewing gum can follow the air from the air inlet 410 into the interior of the sealing cover 300, and then enter the interior of the dust collecting tank 701 through the connecting pipe 702.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
