Abstract
A snow removal blade has a rolling body, a snow-removal knife connected to a bottom portion of the rolling body, a plurality of nozzles for delivering a melting liquid on the snow left on the road surface by the snow-removal knife, and a member for mixing together and pressing the residual snow and the melting liquid, which is arranged behind the snow-removal knife in a direction of advance of the snow removal blade, the snow-removal knife and the mixing and pressing member delimiting between them a channel for lateral outlet of the snow, arranged in which are the delivery nozzles.
Claims13
A method for removing snow from a snow-covered road surface by using a snow removal blade as claimed in claim 6;
- the method comprising the steps of moving the blade forward along the road surface to be cleaned, removing part of the snow with the removal blade allowing a layer of compact residual snow to remain on the road surface and spreading a material for melting the residual snow onto the layer of residual snow, and being characterised by mixing the layer of residual snow with said melting material present in the lateral outlet channel by means of the mixing and pressing member and compressing the layer of residual snow mixed with the melting material onto the road surface, always by means of the pressing member, during the moving forward of the mixing and pressing member.
A snow removal blade for removing snow from a snow-covered road surface;
- the blade comprising:
- a rolling body;
- a removal knife connected to a lower portion of said rolling body and adapted to slide, in use, adjacent to the road surface thus leaving a layer of residual snow on the road surface;
- a feeding assembly, for supplying a snow melting material, the assembly comprising a plurality of delivery nozzles and a circuit for feeding the melting material to said nozzles, characterised in that it furthermore comprises, a mixing and pressing member for the residual snow arranged behind said removal knife in a forward movement direction of the blade;
- the removal knife and the mixing and pressing member delimiting between them, a lateral snow outlet channel, and in that said nozzles comprise respective outlets arranged in said channel for sending the melting material onto the residual snow present in said lateral outlet channel, said mixing and pressing member being configured to mix said layer of residual snow with said melting material arranged in said lateral outlet channel and for compressing the residual snow mixed with said melting material on the road surface during its forward movement.
