A brush roller cleaning assembly fixedly connected to the inner wall of the cover body 1 is sleeved on the brush roller 4, and a transmission assembly is slidably sleeved on the rotating shaft 2. The rotating rotating shaft 2 can drive the brush roller 4 to revolve and rotate at the same time through the output end of the transmission assembly.

[0026] Please combine Figure 1 As shown, when the road surface needs to be cleaned, the hydraulic pressure is operated to move the cover 1 and the rotating shaft 2 downward, the rotating shaft 2 drives the cylinder 3 to move downward, the cylinder 3 drives the brush roller 4 to move downward and fit the road surface, and the cover 1 drives the brush roller cleaning assembly to move downward, thereby realizing the synchronous downward movement of the brush roller cleaning assembly and the brush roller 4, as shown in FIG. Figure 6 As shown, the driving mechanism is then operated to rotate the rotating shaft 2, which drives the cylinder 3 to rotate, and the cylinder 3 drives the brush roller 4 to revolve around the rotating shaft 2 in the cover 1 to clean the road surface. After the road surface is cleaned, the hydraulic pressure is operated to make the cover 1 and the rotating shaft 2 rise, and the cover 1 and the rotating shaft 2 respectively indirectly drive the brush roller cleaning assembly and the brush roller 4 to move and reset;

[0027] When the brush roller 4 needs to be cleaned, the driving mechanism is operated to rotate the rotating shaft 2, and the rotating shaft 2 indirectly drives the brush roller 4 to revolve around the rotating shaft 2. The rotating shaft 2 drives the brush roller 4 to rotate through the transmission component. The brush roller cleaning component cleans the brush roller 4 and scrapes off small particles of impurities between the bristles of the brush roller 4, thereby realizing the cleaning of the brush roller 4 during self-rotation. There is no need to manually clean the brush roller 4. After the brush roller 4 is cleaned, the driving mechanism is operated to stop the rotation of the rotating shaft 2.

[0029] Please combine Figure 1As shown, during use, the operating hydraulic pressure drives the cover body 1 to move, the cover body 1 drives the chute 8 to move, the chute 8 drives the slider 7 to move, the slider 7 drives the U-shaped plate 5 to move, and the U-shaped plate 5 drives the groove 6 to move. When the rotating shaft 2 drives the brush roller 4 to revolve around the rotating shaft 2 through the cylinder 3, the brush roller 4 drives the U-shaped plate 5 to rotate, and the U-shaped plate 5 drives the slider 7 to slide in the chute 8. The setting of the frame 9 serves to connect the multiple U-shaped plates 5 and improve the stability of the U-shaped plates 5.

[0030] When the brush roller 4 rotates and performs self-cleaning, the multiple bristles on the brush roller 4 pass through the groove 6 in sequence, and the groove 6 scrapes off the small particles of impurities between the bristles on the brush roller 4, thereby achieving cleaning of the brush roller 4.

[0031] The opening of the groove 6 is arranged toward the open end of the cover body 1 and the width thereof gradually increases as it approaches the open end of the cover body 1 .

[0032] Please combine Figure 1 As shown, during use, the opening of the groove 6 is set toward the open end of the cover body 1 and the width gradually increases along the open end close to the cover body 1, thereby increasing the coverage of the bristles on the brush roller 4 and facilitating the bristles on the brush roller 4 to enter the groove 6 to clean the brush roller 4.

[0033] Please combine Figure 1 、 Figure 2 、 Figure 6 , transmission component embodiment, the transmission component includes a first bevel gear ring 14 slidingly sleeved on the rotating shaft 2, the bottom end of the first bevel gear ring 14 is meshed with a second bevel gear ring 15, the second bevel gear ring 15 is fixedly sleeved on the brush roller 4, the top surface of the first bevel gear ring 14 is annularly opened with a dovetail groove 13, and a sliding rod 11 matching it is fitted and slidably provided in the dovetail groove 13.

A compression spring 12 is provided between the top of the sliding rod 11 and the sweeper, and the compression spring 12 is arranged in the barrel body 10, and the bottom surface of the cross bar at the top of the sliding rod 11 fits with the inner bottom surface of the barrel body 10.

[0034] Please combine Figure 1 As shown, during use, when the hydraulic pressure pushes the rotating shaft 2 to move downward, the rotating shaft 2 drives the brush roller 4 to move downward through the cylinder 3, and the brush roller 4 drives the second bevel gear ring 15 to move downward and separate from the first bevel gear ring 14, and then the driving mechanism is operated to drive the rotating shaft 2 to rotate, and the rotating shaft 2 drives the brush roller 4 to revolve through the cylinder 3, and the rotating shaft 2 drives the first bevel gear ring 14 to rotate. At this time, the first bevel gear ring 14 is separated from the second bevel gear ring 15, and the first bevel gear ring 14 cannot drive the second bevel gear ring 15 to rotate, so that the brush roller 4 cannot rotate on its own.

[0035] After the brush roller 4 finishes cleaning the road surface, the hydraulic pressure is operated to make the brush roller 4 move upward indirectly to reset, and the brush roller 4 drives the second bevel gear ring 15 to move to reset and engage with the first bevel gear ring 14. If the second bevel gear ring 15 cannot move and engage with the first bevel gear ring 14, the second bevel gear ring 15 will push the first bevel gear ring 14 to move, and the first bevel gear ring 14 drives the slide bar 11 to move and squeeze the compression spring 12 to deform. When the brush roller 4 needs to self-clean, the driving mechanism is operated to rotate the rotating shaft 2. Rotate, if the first bevel gear ring 14 is not engaged with the second bevel gear ring 15, at this time the rotating shaft 2 drives the first bevel gear ring 14 to rotate and align with the second bevel gear ring 15, the deformed compression spring 12 pushes the slide bar 11 to move, and the slide bar 11 drives the first bevel gear ring 14 to move downward and engage with the second bevel gear ring 15 and drive it to rotate. If the first bevel gear ring 14 is engaged with the second bevel gear ring 15, the first bevel gear ring 14 directly drives the second bevel gear ring 15 to rotate, and the second bevel gear ring 15 drives the brush roller 4 to rotate.

[0036] A protective cover 16 is fixedly connected to the bottom surface of the cylinder 3 . The protective cover 16 is rotatably sleeved on the brush roller 4 . The second helical gear ring 15 is arranged in the protective cover 16 .

[0037] Please combine Figure 1 As shown, during use, the protective cover 16 covers the second helical gear ring 15 to protect the normal operation of the second helical gear ring 15 and prevent the second helical gear ring 15 from contacting the road surface and causing wear.

[0038] The number of teeth of the first helical gear ring 14 is much greater than the number of teeth of the second helical gear ring 15 .

[0039] Please combine Figure 1 As shown, during use, the number of teeth of the first bevel gear ring 14 is much larger than the number of teeth of the second bevel gear ring 15, so that the first bevel gear ring 14 drives the second bevel gear ring 15 to rotate rapidly, thereby realizing that the first bevel gear ring 14 drives the brush roller 4 to rotate rapidly through the second bevel gear ring 15 for cleaning.
