## 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.

## Claims

### Claim 1 (depends on 6)

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.

### Claim 2 (depends on 1)

The method according to claim 1, characterised in that the melting material is delivered to area of said layer of residual snow arranged within the channel which is closer to the mixing and pressing member than to said removal knife.

### Claim 3 (depends on 1)

The method according to claim 1, characterised in that said melting material is delivered immediately upstream and/or partially above said mixing and pressing member.

### Claim 4 (depends on 1)

The method according to claim 1, characterised in that the compression of the residual snow mixed with the melting material is carried out by keeping the mixing and pressing member in a fixed position with respect to the rolling body of the snow removal blade.

### Claim 5 (depends on 1)

The method according to claim 1, characterised in that the compression of residual snow mixed with the melting material is carried out by keeping the mixing and pressing member in a fixed position with respect to the removal knife.

### Claim 6

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.

### Claim 7 (depends on 6)

The blade according to claim 6, characterised in that said mixing and pressing member is separated from said removal knife and said nozzles are outside of or separated from both the removal knife and the mixing and pressing member.

### Claim 8 (depends on 6)

The blade according to claim 6, characterised in that said mixing and pressing member is fixed to said rolling body.

### Claim 9 (depends on 6)

The blade according to claim 6, characterised in that said mixing and pressing member is fixed in respect to said removal knife.

### Claim 10 (depends on 6)

The blade according to claim 6, characterised in that said nozzles are arranged closer to the mixing and pressing member than to the removal knife.

### Claim 11 (depends on 6)

The blade according to claim 6, characterised in that said nozzles are arranged alongside said mixing and pressing member.

### Claim 12 (depends on 6)

The blade according to claim 6, characterised in that said removal knife and said mixing and pressing member have respective end surfaces facing, in use, the road surface arranged, in use, at the same height from the road surface.

### Claim 13 (depends on 6)

The blade according to claim 6, characterised in that said removal blade and said mixing and pressing member have respective end surfaces facing, in use, the road surface lying on a shared flat plane.
