[0035] The two groups of second rollers 14 on the front side are steered by the steering mechanism, and the transmission shaft 17 drives the mop frame 5 and the mop cloth 51 to rotate, so that the mop and the rollers are steered synchronously, which is convenient for cleaning the corners of the ground. At the same time, the pitch angle of the mop frame 5 can be adjusted by the first hydraulic cylinder 34, and the height of the mop frame 5 can be adjusted by the second hydraulic cylinder 43.

[0037] Specifically, during the steering process, the handlebar 18 drives the transmission shaft 17 to rotate, and the transmission shaft 17 drives the transmission gear 16 at the lower end to rotate. The transmission gear 16 cooperates with the transmission rack 23 to drive the transmission plate 2 to slide left and right. During the sliding process, the transmission plate 2 drives the second transmission rod 24 and the end connected to the transmission plate 2 to slide left and right. At this time, since the equipment bracket 1 limits the front end of the first transmission rod 12, the second transmission rod 24 drives the first transmission rods 12 on both sides to rotate around their front ends, and at this time drives the side support rods 13 to rotate, and rotates the angles of the second rollers 14 on both sides.

[0038] At the same time, during the rotation of the transmission shaft 17, the transmission shaft 17 drives the fixed plate 3 to rotate, and the fixed plate 3 drives the front support frame 31 to rotate, thereby adjusting the angle of the front mop frame 5 and the mop cloth 51 so that they turn synchronously with the second roller 14.

[0040] In addition, when wiping the irregular ground, the telescopic rod box in the first hydraulic cylinder 34 contracts, thereby driving the rotating plate 4 to rotate upward around the front end of the support frame 31, thereby lifting the mounting plate 42 upward, and at the same time lifting the mop frame 5 and the mop cloth 51 upward, and then the second hydraulic cylinder 43 pushes the mop frame 5 downward until the rear side of the mop frame 5 is in close contact with the ground. At this time, the front ends of the mop frame 5 and the mop cloth 51 are tilted upward, and their rear ends are in close contact with the ground, and the whole is inclined.
