[0023] The invention is used as follows: It features a simple and reasonable structure, low production cost, and convenient installation. In use, motor 2 (310) is first started to drive the drive gear 2 (39) to rotate. The rotation of the drive gear 2 (39) then sequentially drives the driven gear 2 (311), transmission sleeve 1 (312), end face gear 2 (37), connecting gear 2 (38), transmission shaft 1 (35), and connecting gear 1 (34) to drive the end face gear 1 (33) and rotating sleeve 31 to rotate at low speed. The low-speed rotation of the rotating sleeve 31 cleans the ground through brush 1 (314). Because the outer brush 1 (314) is in a low-speed cleaning state, it prevents stones from flying and hitting cars and pedestrians on the roadside. Motor 3 (515) is then started to drive the transmission shaft 2 (512) to rotate.

The rotation of the transmission gear 1 (58) then drives the end face gear 3 (55) to rotate through spline shaft 59. 7 drives the rotating ring 54, connecting plate 55, and brush bristles 56 to rotate at high speed, thereby improving the cleaning effect. In addition, even if stones fly out, they will be blocked by the outer brush bristles 314 and protective sleeve 313, thus preventing stones from flying out and hitting cars and pedestrians on the roadside. The motor 4 518 can drive the driven gear 3 516, transmission sleeve 2 519, transmission gear 4 514, transmission gear 3 513 and screw 52 to rotate in sequence through the driving gear 3 517.

In addition, the motor 10 can drive the rotating seat 4 to rotate as a whole through the driving gear 9 and driven gear 11, so that the rotating connecting plate 55 and brush bristles 56 can be rotated to any position inside the outer brush bristles 314 for cleaning, thus improving the convenience of cleaning.
