The round brush sets up on round brush main part case, goes up and down through electric putter, and the round brush can go up and down for round brush main part case promptly.
Compared with the prior art, the invention is greatly modified about the lifting structure of the rolling brush. The rolling brush 2 is arranged on the rolling brush main body box 1 through a rotating shaft and a bearing (the connection mode of the rolling brush 2 and the rolling brush main body box 1 is not limited in the application, as long as the rolling brush 2 can rotate and realize the function of the sweeper). Further, in the present invention, the roll brush main body casing 1 is not fixed to the sweeper but is rotatable about a fulcrum.
In this embodiment, the roller brush main body box 1 and the dust box 28 of the sweeper are welded together, the dust box 28 is arranged on the support frame on the chassis frame 24 of the sweeper, the end of the support frame is provided with the first connecting plate, the roller brush main body box is provided with the second connecting plate, and the first connecting plate and the second connecting plate are connected through the rotating connecting shaft 23, so that the roller brush main body box 1 and the dust box 28 can rotate around the rotating connecting shaft 23. A hydraulic cylinder 26 is obliquely fixed on the chassis frame 24 of the sweeper, and one end of the hydraulic cylinder 26 is connected to a hydraulic cylinder lug seat I25 through a pin shaft; a piston rod of the hydraulic cylinder 26 is connected to a second hydraulic cylinder lug seat 27 through a pin shaft; the first hydraulic cylinder lug seat 25 is fixed on the chassis frame 24 of the sweeper, and the second hydraulic cylinder lug seat 27 is fixed on the roller brush main body box 1. When the piston rod of the hydraulic cylinder 26 extends, the roller brush main body case 1 can rotate clockwise around the fulcrum, and the roller brush can ascend.
An ear seat bottom plate 12 is fixed at the position of the sweeper main body box 1 close to the front end, a connecting arm ear seat 11 is fixed on the ear seat bottom plate 12, and the connecting arm 9 is connected with the connecting arm ear seat 11 through a pin shaft 10. The other end of the connecting arm 9 is connected with an upstream rotating arm 8 through a pin shaft, and the other end of the upstream rotating arm 8 is fixed on the sweeper lifting rotating shaft 7. The sweeper lifting rotating shaft 7 is fixed between two pedestal bearings 16, and the pedestal bearings 16 are fixed on the sweeper chassis frame 14 through bolts. And a first downstream rotating arm 13 and a second downstream rotating arm 17 are also fixed on the sweeper lifting rotating shaft 7.

Specifically, the sweeper arm 4 is fixed to a cross bearing 22, the cross bearing 22 is fixed to a cross bearing mount, and the cross bearing mount is fixed to the sweeper chassis frame 14.
According to the sweeper brush and roller brush integrated lifting mechanism of the sweeper, when the piston rod of the hydraulic cylinder 26 extends, the roller brush main body box 1 integrally rotates clockwise by taking the rotating connecting shaft 23 as a fulcrum, namely, the front half part of the roller brush main body box 1 rises upwards around the fulcrum, so that the roller brush 2 rises. Meanwhile, in the process that the rolling brush main body box 1 rises, the connecting arm 9 is subjected to an upward oblique force, the connecting arm 9 presses the upstream rotating arm 8 downwards, the upstream rotating arm 8 drives the sweeping brush lifting rotating shaft 7 to rotate anticlockwise, the downstream rotating arm I13 and the downstream rotating arm II 17 respectively drive the rotating shaft stay wire I3 and the flexible shaft stay wire II 6 to pull backwards, and the sweeping brush arm 4 drives the sweeping brush 5 to rise after being subjected to an upward oblique pulling force; due to the arrangement of the cross bearing 22 and the sweeping tension spring 19, the sweeping arm 4 can flexibly rotate and can be lifted in a buffering way. When the piston rod retracts, the actions are opposite, the sweeper brush 5 and the rolling brush 2 descend simultaneously, namely, the lifting of the sweeper brush and the lifting of the rolling brush are realized simultaneously through one hydraulic cylinder.
