Abstract
The invention relates to a friction snowplough comprising a device having a parallelepiped shape and a heavy weight, designed to remove snow that forms on asphalt in extreme weather conditions and situations. The operation of the snowplough is based on friction between two moving bodies. The work required to move the two bodies is transformed into heat energy which is absorbed by the ice, melting same. The heavy weight takes the form of a regular hexahedron (1) of which: the front part forms an acute dihedral angle (2) that is equipped with a securing element (3) that can be coupled to the tractor vehicle: and the rear part comprises a transverse hitch embedded in the heavy weight and having at least one roller (5) assembled thereto.
Description
FRICTION SNOWPLOUGH
Technical field The specification relating to the friction snowplough makes reference to a device for cleaning snow and ice from asphalt roads, this device being placed on the rear portion of a traction vehicle.
The friction snowplough is a heavy mass in the shape of a regular hexahedron with a protuberance on the front portion formed by an acute regular dihedron.
The snowplow is operated with a tractor machine, and the coupling of the snowplow to the tractor is carried out by means of a three-point attachment.
Background of the invention The snowploughs used to clean asphalt roads have evolved according to the function for which they are required. At the outset, wood triangles covered with metal that were towed around by tractor vehicles were used. Later on the snowplough was installed in the front portion of the tractor vehicle. These snowploughs were formed by a steel sheet shaped as a blade intended for scraping and removing snow and ice thanks to a dynamic effect, i.e., by a pushing force.
There are designs of trucks which incorporate gas burners to melt the snow, but those solutions are very sophisticated and too expensive.
Other systems used in alpine locations are pieces of equipment that collect snow and expel it through the action of a rotor. They are the so-called steerable snow sweepers, turbine snow sweeper or destroying arm.
The assemblies of snowplough with a steel blade carried on the front portion of the tractor vehicle work fine under mildly severe conditions, i.e., when the temperature does not drop many degrees Celsius.
For temperatures below zero degrees Celsius, the situation on the asphalt pavements becomes more complicated, as after the snowplough has passed there remains an ice layer that is strongly adhered. In such cases, chemical compounds such as common salt (sodium chloride) and urea are used. In extreme ice conditions, extreme changes in temperature along with the chemical compounds damage the pavement, and over time the asphalt deteriorates, i.e. the asphalt is attacked both physically and chemically.
When snowplough systems provided with a steel blade are at work on deteriorated asphalt pavement, it causes patches of asphalt to break and come loose, giving rise to potholes.

2 The friction snowplough object of the invention has basis on a friction force originated by the dragging force of a mass over the pavement, i.e., the sliding of a heavy mass.
Snowploughs with a steel blade do not operate well under certain circumstances, these circumstances being when there is a thin ice layer that is firmly adhered to the surface.
The present invention presents a friction snowplough, which is used to remove ice from a surface using a friction energy between two surfaces, wherein the coefficient of friction is small, but the mass being moved is large.
Description of the invention An object of the invention is the creation of a snowplough based on the physical processes that take place when towing a block with a given mass over a surface.
The friction snowplough consists of a heavy mass formed by a regular hexahedron, which has an acute dihedron. The mass has in the front portion thereof, which corresponds to the acute dihedron, a three-point anchoring element used to fix the snowplough to a tractor machine. The three-point element has a mass-lifting function by means of the hydraulic device of the tractor machine.
On the rear portion of the heavy mass, i.e., the regular hexaedron, a hook is coupled so as to place a roller system. The wide roller that rotates has two functions, the first one consists of driving the tool rotationally and the second one of melting the ice that remains after the frictionning heavy mass has passed by. The friction snowplough can bear one roller or more, depending on how the device operates.
The forces generated when towing a mass made of a heavy material over the thin ice layer that is adhered to the asphalt can be divided into two types of forces: firstly when the mass remains static on the surface, there is a static friction force with a coefficient of static friction and secondly, when the mass moves over the surface then the inertia force of the bodies has been overcome and turns into a dynamic friction force with a coefficient of dynamic friction.
The energy consumed by the friction force of the two bodies does not disappear, it just dissipates in the form of heat; this heat energy is captured by the ice, thus melting and diluting it. In this way the ice layer thaws, melts and detaches itself.

Practical embodiment of the invention The present specification is based on the physical processes that take place when towing a block with a given mass over a surface.
Following this process it is possible to constitute this snowplough, which is specially indicated to work under extreme ice conditions where current snowploughs leave a thin ice layer that cannot be separated from the asphalt when they operate.
The friction snowplough is intended for towing a heavy mass over the ice layer under extreme temperature conditions. The friction or frictional resistance is a contact force that acts to oppose the sliding motion between two or more surfaces. The force acts parallel to the surface and opposite to the sliding direction.
According to the laws of physics:
F= m = a F friction = F applied The static friction has a different coefficient for the various materials.
Fr= us = Fn The kinetic friction has a different kinetic coefficient for the various materials.
Ff = uk = Fn Examples of coefficients of friction for different surfaces are:
Ice/ ice us= 0.1 uk = 0.03 Rubber! Dry Cement us= 1.0 uk = 0.8 Rubber! wet cement us= 0.3 uk = 0.25 Ski (waxed) / Snow (0 ) us= 0.1 uk = 0.05 The coefficient of kinetic friction for a rubber/ice surface is very small, therefore the mass has to be large to counter the friction force, which is the force transforming into caloric energy.
As shown in figures 1 and 2 the snowplough is formed by the mass volume of a material, in the shape of a regular hexahedron (1), the front portion of the mass being an acute dihedron (2). It is at the front portion of the mass, in the acute dihedron (2), where the attachment system (3) is embedded. Said attachment system is based on a three-point element.
At the end portion of the mass volume (1) is located an embedded cylinder (4) where a roller (5) is coupled.

In figure 3 a second practical embodiment of the invention is shown, in which to
4 the volume mass formed by a regular hexahedron (1) and with the acute dihedron (2) arranged at the front area of the snowplough, a wheeled support (7) has been added on the rear portion of the regular hexahedron (4) and on the front portion where the acute dihedron (1) is formed. In this practical embodiment the three-point support and the roller embedded in the mass (4) are provided in order to couple the double-roller (6) used.
The material of the wheels of which the roller (5) or the double-roller (6) as well as the heavy mass are formed is preferably rubber. The wheels and the heavy mass have patterns on the contacting surface. The mass, which has a large volume, weighs between three and four thousand kilograms.
As can be observed in figure 4, the tractor vehicle (8) hooks together with the fastening element (3) the large volume mass, which has the shape of a regular hexahedron (1). By means of the lifting elements, with which the tractor vehicle (8) is itself provided, the front portion of the mass, i.e, an acute dihedron (2), is lifted above the ground level (9) thus preventing wear thereof due to rubbing while it is conveyed up to the point of operation.
The friction snowplough is an alternative to steel blade snowploughs to clean roads, airports or concrete pavements that have an ice layer adhered to them.
The material of the wheels of which the roller (5) or the double-roller (6) as well as the heavy mass are formed is preferably rubber. The wheels and the heavy mass have patterns on the contacting surface. The mass, which has a large volume, weighs between three and four thousand kilograms.
