Delta V=shaped snow plough for roads - has exterior ramps to lift and reject snow to edge of road

摘要

The snow plough (1) has two forward orientated concave edged blades (2, 3) and exterior ramps (5) to lift and reject the snow above any snow bordering the carriageway. Snow moved from the centre to the edge of the carriageway will mount the ramp when there is edge snow, and will move onto plate (7) which is defined by the plane vertical guide (9) and the inverse L-shaped streamline guides (8). The plate pivots about the vertical axis (10) and has a height above rejected snow on the carriageway edge.
