FIELD: ice-technology.
SUBSTANCE: invention relates to removal of snow-ice drift from road surface. Device for removal from road surface of snow-ice rolling consists of disks having cutting edges and installed on two mating at an angle α<180° axis. Discs cutting edges are wavy, and discs on axes provide their synchronous rotation and co-direction of waviness corrugation. Discs have shape of ellipses with their co-directional larger semi-axes, axes are interconnected by means of gimbal transmission, and pitch of corrugation of edges is selected from condition of equality of frequency of horizontal loads acting on rolling to frequency of own horizontal oscillations of device at specified speed of its movement.
EFFECT: invention improves efficiency of cleaning road surfaces from snow-ice drift.
