Railway vehicle and stone sweeping machine thereof

The invention discloses a stone sweeping machine. The stone sweeping machine is characterized in that a support of the stone sweeping machine is fixed onto the front end surface of an axle box, and a stone sweeping structure is fixed to the front side of a wheel set by the aid of the support. The stone sweeping machine can be repositioned, can be fixed onto the axle box and can be guaranteed against being affected by vibration of a primary spring, change of the distance from the stone sweeping machine to a rail surface can be greatly reduced, accordingly, obstacle removing effects can be improved, and high-speed running of a railway vehicle can be effectively guaranteed. The stone sweeping machine has the advantages that the stone sweeping machine is mounted on the axle box and is simple in structure, and good stone sweeping effects can be realized; the support of the stone sweeping machine with the structure is free of weld rib plates, and accordingly weld cracks can be prevented; the distance from a rubber
