The invention belongs to the technical field of cleaning equipment, and in particular relates to a cleaning equipment used on a construction site. During the working process of the cleaning machine, if it encounters uneven ground, the rotation of the steel wire will be blocked and swing on the convex surface, and the impact of the convex surface on the steel wire will be prevented by swinging to prevent the steel wire from breaking or wearing. In the present invention, during the normal rotation of the steel wire, the arc-shaped tooth plate installed on the steel wire rotates until the brake gear contacts, that is, when the steel wire touches the ground particles, the swing of the steel wire is limited by the brake gear; Clean the ground particles on the ground to eliminate the impact of steel wire swing on cleaning. The two support wheels designed by the present invention can support the installation cylinder, so that the steel wire installed on the installation cylinder is supported by the two support wheels, which can prevent the steel wire from directly contacting the ground and increase the wear of the steel wire.
