Snow-clearer with turbine rotating on a transverse horizontal axis, fed by two frustroconical lateral connected elements

摘要

The snow clearer has in front one or more cylinders or drums rotating on a transverse horizontal axis, each formed by three elements, of which a central one (2) is a turbine and the other two lateral (4, 5) frustroconical, convergent toward the turbine and equipped on their external conical surface with opposed helicoidal ribs (5) of height increasing toward the centre, so as to keep an external cylindrical occupation of space. The two lateral frustroconical elements (4,5) function to collect snow toward the central turbine (2), which provides for the expulsion of the said snow through the orientable path (3). The turbine (2) has planar radial palettes, provided on their base with a concave dish (8) which may favour throwing the snow centrifugally.
