Anti-winding sweeping robot and working method thereof

The invention relates to the field of sweeping robots, in particular to an anti-winding sweeping robot and a working method thereof. A roller brush cover; the roller brush comprises a roller shaft and a dust brushing piece arranged on the periphery of the roller shaft, limiting sliding grooves are coaxially formed in the two ends of the roller shaft around the arc side faces of the roller shaft respectively, and the roller shaft is divided into two semicircular rollers which are symmetrical left and right along the axis of the roller shaft. A driving motor; the limiting sliding grooves of the two semicircular rollers are in sliding fit with one ends of the roller shaft supporting parts correspondingly. The first telescopic mechanism drives the connected semicircular roller to be far away from the other semicircular roller in the horizontal direction through the roller shaft supporting part; the second telescopic mechanism drives the connected semicircular rollers to be close to the dust suction opening in the
