Railway track deicing and impurity removing device

The invention provides a railway track deicing and impurity removing device which is characterized in that thick-layer accumulated snow covering the surfaces of rails and rail sleepers is firstly removed through an accumulated snow sweeping mechanism arranged at the front end of a track carrying mechanism, so that the space between the two rails is kept clean; then an ice breaking assembly of the rail deicing mechanism crushes an icing layer on the surface of the rail, finally, an ice residue melting assembly of the rail deicing mechanism sprays high-temperature airflow to quickly melt ice residues obtained after the surface of the rail and the ice layer on the surface of a rail sleeper, and the surface of the rail and the surface of the rail sleeper can be quickly dried and cannot be re-iced; in this way, the train cannot slip when running on the rail, and the problems that a large amount of ice and snow are drawn into the train when the train runs at a high speed and accumulated on a train chassis and a bog
