Use the gravity of the decompression weight to react on the rotating sleeve, and through the rotating sleeve to react on the swing rod, fixed shaft and rotating brush, reduce the pressure of the rotating brush on the target track, and avoid the excessive pressure of the rotating brush on the track.

Preferably, the rotating brush includes a linkage ring, bearings and bristles, the bristles are uniformly and fixedly connected to the outside of the bearing, and the linkage ring is fixedly connected to the outside of the bearing.

The wheel body is used to drive the linkage ring to rotate the outer ring of the bearing, and the bearing drives the bristles to reverse along the target track to discharge dust particles, which facilitates the outward sewage discharge.

Preferably, the rotating brush further includes a leather ring, and the leather ring is fixedly connected to the outside of the linkage ring.

The leather ring is used to increase the friction between the linkage ring and the wheel body, which facilitates the wheel body to drive the rotating brush to rotate.

In summary, the technical effects and advantages of the present utility model: 1. When the trolley body moves, the wheel set is rotated, and the swing frame is connected with the wheel set to rotate, and the gravity of the swing frame and the rotating brush is used to sag to make the wheel set rotate. The rotating brush is in stable contact with the track, and the rotation of the wheel set drives the rotating brush to rotate in the opposite direction, which facilitates the cleaning of dust along the way to ensure the cleanliness of the track.

2. Use the rotating sleeve to guide the swinging rod to swing, so that the rotating brush and the fixed shaft can act downward on the rotating brush with their own gravity, thus ensuring the stability of the contact force between the rotating brush and the track.

3. Use the gravity of the decompression weight to react on the rotating sleeve, and through the rotating sleeve to react on the swing rod, fixed shaft and rotating brush, reduce the pressure of the rotating brush on the target track and avoid the excessive pressure of the rotating brush on the track.

4. Use the wheel body to drive the linkage ring to rotate the outer ring of the bearing, and drive the bristles to reverse along the target track to discharge dust particles through the bearing, which facilitates the outward sewage discharge.
