Description of the drawings:

fig. 1 is a schematic perspective view of the present invention;

FIG. 2 is a schematic view of the three-dimensional structure of the present invention with the outer shell removed;

FIG. 3 is a flow chart of the automatic adjustment of the main brush according to the present invention;

the reference numbers are as follows: a vehicle body 100; a main brush fixing mechanism 200; a fixing bracket 210; a swing arm 220; a first driven pulley 221; a second driven pulley 222; a linear driver 230; a drive device 240; a drive wheel 241; a brush 300.

The specific implementation mode is as follows:

the following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be clearly and clearly defined.

As shown in fig. 1 and 2, a cleaning robot with a main brush lifting device includes a vehicle body 100, a main brush fixing mechanism 200 is disposed on the vehicle body 100, the main brush fixing mechanism 200 includes a linear driver 230 fixedly connected to the vehicle body 100, a first driven wheel 221 and a second driven wheel 222 are disposed at two ends of a swing arm 220 respectively, a driving wheel 241 on an output shaft of a driving device 240 drives the first driven wheel 221 to rotate, the first driven wheel 221 drives the second driven wheel 222 to rotate, one end of the driving device 240 is hinged to the vehicle body 100, the other end is hinged to a fixing support 210, and the fixing support 210 is fixedly connected to one end of the swing arm 220 where the second driven wheel 222 is located.

As shown in fig. 1, two main brush fixing mechanisms 200 are symmetrically disposed at both sides of the vehicle body 100, a linkage shaft is disposed between two first driven wheels 221 of the two main brush fixing mechanisms 200, and the two main brush fixing mechanisms 200 are independent from each other and have one end linked, so that the brush 300 can be tilted in a small range to adapt to wear and tear

As shown in fig. 2, the linear actuator 230 is an air cylinder, the driving device 240 is a motor, and the driving pulley 241, the first driven pulley 221 and the second driven pulley 222 are driven by a belt.
