Friction Snowplough

Abstract

The friction snowplough is a parallelepiped-shaped device that has a heavy mass, designed to remove the ice formed on the asphalt in extreme weather conditions and situations. Its operation is based on the friction work of two bodies in movement. The work used to move two bodies is transformed into heat energy, which is absorbed by the ice thus proceeding to melt it. The heavy mass has the shape of a regular hexahedron (1) and at the front portion it forms an acute dihedron (2) where a fastening element (3) is arranged so as to be coupled to the tractor vehicle, and at the rear portion of the regular hexahedron (4) there is a transversal hook embedded in the heavy mass, and in the aforementioned embedded rear hook at least one roller (5) is assembled.

1 . A friction snowplough that comprises a heavy mass to be towed by a tractor vehicle, wherein the heavy mass has a shape of a regular hexahedron ( 1 ) having a front portion forming an acute dihedron ( 2 ) where a fastening element ( 3 ) is arranged so as to be coupled to the tractor vehicle ( 8 ), and a rear portion of the regular hexahedron ( 4 ) including a transversal hook embedded in the heavy mass, the transversal hook comprising at least one roller ( 5 ). 
     
     
         2 . The friction snowplough according to  claim 1 , wherein the fastening element comprises three-point element formed by two hooks and a central adapter. 
     
     
         3 . The friction snowplough according  claim 1 , wherein the roller comprises a plurality of wheels that rotate freely around its axis. 
     
     
         4 . The friction snowplough according to  claim 1 , wherein the heavy mass comprises a wheeled support ( 7 ) at the rear portion of the regular hexahedron ( 4 ) and at the front portion where the acute dihedron ( 2 ) is formed. 
     
     
         5 . The friction snowplough according to  claim 1 , wherein the material of the wheels and the heavy mass comprises rubber. 
     
     
         6 . The friction snowplough according to  claim 1 , wherein the wheels and the heavy mass have a pattern on the contacting surface. 
     
     
         7 . The friction snowplough according to  claim 1 , wherein the mass weighs between three thousand and four thousand kilograms.
