<p>An extensible snowplough blade comprises a fixed blade body (10), having a substantially linear conformation in a longitudinal direction and is provided, at a posterior surface (11 ) thereof, with means for support (12). It further comprises a raising structure (20) for defining a hinged connection between the blade body (10) and a vehicle (150). The raising structure (20) in turn comprises a frame (21 ) for fixing thereof to the vehicle (150) and coupling means (25) of the fixed frame (21) to the means for support (12). The extensible snowplough blade (100) further comprises a first extension (30), slidably mounted on the means for support (12) in a parallel position to the blade body (10) and destined to extend longitudinally with respect to the blade body (10) in a left-wards direction, and a second extension (40), slidably mounted on the means for support (12) in a parallel position to the blade body (10) and destined to extend longitudinally, with respect to the blade body (10), in a right-wards direction. Adjusting means (6) are further provided in the raising structure (20) in order to regulate an angle of incidence to the ground of the snowplough blade (100).</p> |
