FIELD: road construction and municipal engineering.

SUBSTANCE: invention relates to road construction and municipal engineering, in particular to devices for removing snow from roads. A snow clearing device contains a case with a pruning knife, a feeding screw with a loosening tip and a bladed rotary thrower, coaxial with the screw. The lateral lower part of the case has a spherical shape, and the feeding screw is made with a constant diameter and pitch of a screw line, as well as with a decreasing depth of a screw channel of the screw along its axis in the course of snow movement. At the same time, this part of the screw is located in the snowplow case, and the rest of it is a conventional shaft connected to a drive, on which a blade rotor of the throwing device is located behind the case.
