Patent Description:
In particular, the present invention refers to an assembly intended for removing layers of asphalt or similar material and the cold recycling thereof for direct repositioning on the portion of road pavement just removed.

The use of excavating devices connectable to operating machines, such as machines for earth moving, for example excavators or bulldozers or wheeled or tracked loaders for removing layers of asphalt or similar materials, is known.

It is further known that for restoring road pavements it is possible to recycle in place the bituminous layers removed from the road surface in a cold process so as to repair damaged road pavements, for example with the presence of holes or cracks of the surface.

In general, the damaged bituminous layers in cold recycling are scarified and shredded, and the obtained milled material is then regenerated with the addition of binding agents and then compacted and re-laid on the road bed.

In this type of intervention, dedicated and bulky regeneration machines are utilized which receive the milled conglomerate, regenerate it and transfer it via a conveyor belt to a road paver that follows the recycling machine and proceeds to spread the regenerated conglomerate immediately.

Inconveniently, the operation for restoring the road surface by using said regeneration and paving machines turns out to be burdensome, both from the standpoint of time and in terms of the costs and of the road and transport bulkiness. In fact, in an inconvenient manner, the systems of the prior art require the milled material to be set aside in a dedicated regeneration machine, which recycles the milled material, which is then reconveyed to the paving machine.

Therefore, this solution turns out to be not suitable for restoring small zones of damaged road surface and is generally utilized for resurfacing large surfaces.

Inconveniently, furthermore, the resurfacing of the road surface according to the prior art requires that, once the regeneration machines have carried out the regeneration of the milled conglomerate and its redeposition on the road surface, a further layer of new hot conglomerate is also applied in order to create the wear-resistant layer. Therefore, according to the prior art, the regenerated milled conglomerate serves only as a carrier layer for receiving the new hot conglomerate on which the road traffic then operates. In an inconvenient manner, therefore, it is nevertheless necessary to deposit the new conglomerate, and it is not possible to create a road surface exclusively with recycled conglomerate.

Examples of prior art can be found in documents <CIT>, <CIT> and <CIT>.

Therefore, the need for speeding up and rendering the road surface resurfacing procedure simpler and more streamlined remains strongly felt, especially for relatively reduced surface areas of damaged road surface.

Furthermore, the need remains strongly felt for a device that allows for restoring of the damaged road surface that is compact, streamlined and effective, and does not require bulky supporting machines. In particular, the need is felt for a streamlined device that does not require self-propelled regeneration machines of enormous dimensions, typically provided with their own means for movement on the road integrated into the machine itself.

Furthermore, the need is felt for a device that allows the restoring of a damaged road surface by utilizing recycled conglomerate and without the need for further superficial treatments with the addition of new hot conglomerate.

These and other purposes are achieved by means of a scarification and recycling assembly, an operating machine and a method for restoring the road surface according to the attached independent claims.

Some advantageous embodiments are the subject of the dependent claims.

Further features and advantages of the invention will become clear from the description given below of its preferred embodiments as non-limiting examples, in reference to the attached figures, wherein:.

In reference to the attached figures, the reference number <NUM> designates, in its entirety, a cold scarification and recycling assembly <NUM> for restoring a damaged road pavement P, which has holes or cracks at least in its outermost layer. The cold scarification and recycling assembly <NUM> (or, more simply, the scarification and recycling assembly <NUM>) is an integrated assembly which carries out both the functions of scarification of the road pavement and of cold recycling (that is, regenerating the conglomerate for reapplication) in a single machine. Said scarification and recycling assembly <NUM> is further suitable for being directly connected to a mobile arm of an operating machine <NUM>, for example a mini-loader, or a tractor. As is more clearly visible in the figures from <NUM> to <NUM>, it is clear that the scarification and recycling assembly <NUM> may be configured both for being pushed and for being towed by the operating machine <NUM>, according to the working need. For example, it may be hitched to the rear of a tractor, as shown in <FIG> and <FIG>, or moved forward or in reverse, as shown in <FIG>, on a loader or mini-loader.

As a function of the operating configuration, the scarification and recycling assembly <NUM> is therefore configured so that the scarification group <NUM> is always before the recycling group <NUM> in the direction of advancement Y.

It is clear that, in the present description, the terms "scarify" or "scarification" are also intended to mean the operation of milling the road surface.

In one embodiment, the scarification assembly comprises an assembly body <NUM>'.

In one embodiment, the scarification assembly comprises an auto-leveling body <NUM>.

Said scarification and recycling assembly <NUM> preferably comprises an assembly body <NUM>' and an auto-leveling body <NUM>.

It is worth pointing out that, unless otherwise specified, the terms "axial", "radial" or "tangential" are always in reference to a rotation axis.

In one embodiment, the assembly body <NUM>' comprises a coupling portion <NUM> to the operating machine <NUM> for its stable mounting, for example for mounting the assembly body <NUM>' to a mobile arm or to a support of the operating machine.

Preferably, the auto-leveling body <NUM> comprises a pair of contact skids <NUM>, <NUM> with the level of the road pavement P.

According to one embodiment, the position of the contact skids <NUM>, <NUM> with respect to the assembly body <NUM>' is adjustable.

In accordance with said variant, the assembly <NUM> could advantageously comprise a device <NUM> for adjusting the excavation depth D' for each contact skid <NUM>, <NUM>.

According to one embodiment, the auto-leveling body <NUM> is therefore rotatable parallel to a rotation axis that is parallel to the road pavement plane P.

According to one embodiment, the auto-leveling body <NUM> is guided by the assembly body <NUM>' in the various angular positions via guiding means cooperating with said bodies <NUM>, <NUM>'.

According to one embodiment, the guiding means comprise at least one edge of a guide slot <NUM>' slidingly engaged by at least one guide pin <NUM>.

The scarification and recycling assembly <NUM> is therefore movable in a working direction (or advancing direction) Y while maintaining the sliding contact between the contact skids <NUM>, <NUM> and the plane of the road pavement P.

According to one embodiment, the contact skids <NUM>, <NUM> are arranged adjacent to one another and spaced apart in front of the other.

According to one embodiment, the contact skids <NUM>, <NUM> are created by means of bent metal sheets.

According to one embodiment, the assembly body <NUM>' is at least partially housed between the contact skids <NUM>, <NUM>.

According to one embodiment, the assembly body <NUM>' is mechanically connected to the auto-leveling body <NUM> so as to apply weight in a balanced manner to the contact skids <NUM>, <NUM>.

According to one general embodiment, the cold scarification and recycling assembly <NUM> comprises a scarification group <NUM> housed in a first region D of the scarification and recycling assembly <NUM>. Said scarification group <NUM> comprises an excavation tool <NUM> for removing the conglomerate material of one or more layers of asphalt along a linear advancement path along a working surface S of the road pavement P in order to obtain a scarified conglomerate material C.

Furthermore, the cold scarification and recycling assembly <NUM> comprises a recycling group <NUM> housed within a second region R of the scarification and recycling assembly <NUM>. Said recycling group <NUM> comprises a mixing and shredding element <NUM> of the scarified conglomerate material C.

Said second region R is arranged downstream of the first region D, so that the scarified conglomerate material C (or milled conglomerate C) from the scarification group <NUM> is receivable by the recycling group <NUM> for the regeneration thereof into regenerated conglomerate material CR (or regenerated milled conglomerate CR).

Drive means <NUM>, <NUM> are suitable for moving the excavation tool <NUM> and the mixing and shredding element <NUM>.

According to one embodiment, the drive means <NUM>, <NUM> are of the hydraulic type, for example hydraulic actuators.

According to one embodiment, the drive means <NUM>, <NUM> are of the electric type, for example electric motors.

The cold scarification and recycling assembly <NUM> also comprises an interception device <NUM>, which at least partially separates the first region D from the second region R to convey the passage of the scarified conglomerate material C from the first region D to the second region R.

According to one embodiment, the interception device <NUM> is suitable for being maintained in support against the base of the road surface being worked and for being passively guided in translation along a translation direction Z in order to follow the course of the base of the road surface being worked.

According to one embodiment, the interception device <NUM> is actively movable in a close configuration and in an open configuration.

In the closing configuration, the interception device <NUM> prevents the passage of milled conglomerate material C from the scarification group <NUM>, i.e., from the first region D, to the recycling group <NUM>, i.e., the second region R. In the open configuration, the interception group <NUM> allows the passage of milled conglomerate material C from the scarification group <NUM>, i.e., from the first region D, to the recycling group <NUM>, i.e., to the second region R.

The cold scarification and recycling assembly <NUM> also comprises a water and/or regenerating fluid dispensing device <NUM> suitable for dispensing water and/or regenerating fluid directly in the first region D and/or in the second region R.

Preferably, the cold scarification and recycling assembly <NUM> comprises a pump group <NUM> configured for collecting water and/or regenerating fluid from a tank and conveying it toward the water and/or regenerating fluid dispensing device <NUM>.

The regenerating fluid is a fluid suitable for again allowing the cohesion between the granules of the milled conglomerate so as to allow the restoration of the road pavement once the regenerated milled conglomerate is recompacted.

The term "regenerating fluid" is therefore intended to also mean an additive fluid or a bituminous binding agent.

For example, the regenerating fluid is a bitumen mixture or a mixture containing a hydrocarbon binding agent.

In an advantageous manner, the regenerating fluid is preferably the fluid sold under the commercial name Iterlene ACF <NUM> HP GREEN by the company Iterchimica Srl, Bergamo, Italy.

It is clear that a further object of the present invention is the use of a regenerating fluid, and in particular the use of a bitumen mixture or a mixture containing a hydrocarbon binding agent, preferably of the fluid sold under the commercial name Iterlene ACF <NUM> HP GREEN by the company Iterchimica Srl, Bergamo, Italy, for restoring a road surface in a cold process directly on the street, and more particularly the use of a cold scarification and recycling assembly <NUM> according to the present invention or the use in a method for restoring a road surface according to the present invention (described below in the present description).

The cold scarification and recycling assembly <NUM> further comprises a sieving element <NUM> arranged downstream from the recycling group <NUM> and suitable for receiving the regenerated conglomerate material CR and sieving a predefined particle size of regenerated conglomerate material CR for transfer to the working surface S.

The sieving element <NUM> is an element suitable for preventing the passage of a determined size of milled conglomerate material C or of regenerated conglomerate material CR in order to keep it broken up in the recycling group <NUM> unless a desired, typically finer, size of the granules of the material is reached, which material is then discharged downstream of the sieving element, for example because it passes through the apertures or the meshes of the sieving element <NUM>.

The sieving element <NUM>, therefore, allows the passage of the granules of the milled conglomerate material C or of the regenerated conglomerate material CR from the recycling group <NUM> toward the working surface S only upon reaching a desired size of the granules (i.e., the discharge only of the milled conglomerate material or of the regenerated conglomerate CR having a determined size).

According to one embodiment, the assembly body <NUM>' is connected to the auto-leveling body <NUM> via at least one adjusting device <NUM> for adjusting the excavation depth D' of the assembly <NUM>.

The function of the adjusting device <NUM> according to said variant is therefore that of modifying or adjusting the protrusion of the excavation tool <NUM> with respect to the contact skids <NUM>, <NUM> and, thus, adjusting the excavation depth D'.

It is worth pointing out that the adjusting device <NUM> is operated (for example via the wrench or the adjusting tool U, or in a pneumatic, hydraulic, mechanical or electric manner) for the purpose of determining the excavation depth D'.

Nevertheless, after the desired excavation depth has been fixed (that is, after the lower or greater protrusion of the excavation tool <NUM> with respect to the contact skids <NUM>, <NUM> has been determined), said device <NUM> preferably keeps said adjustment or setting constant or unchanged for the entire determined excavation operation.

This type of adjusting device <NUM> has been discussed only by way of example. Other modes of adjusting the excavation depth according to other embodiments are possible.

According to one embodiment, the excavation tool <NUM> is a milling drum which is rotatable about a milling drum rotation axis X substantially parallel to the working surface S of the road pavement P. The milling drum is provided with cutting elements <NUM> for removing the conglomerate material of the road surface.

According to one embodiment, the mixing and shredding element <NUM> is a mixing drum, rotatable about a mixing drum rotation axis X' which is parallel and spaced apart with respect to the milling drum rotation axis X. The mixing drum is preferably provided with protruding elements <NUM>, for example elements projecting radially with respect to the mixing drum rotation axis X'.

Preferably, the scarification group <NUM> comprises a scarification chamber <NUM> in which the excavation tool <NUM> is housed, and the recycling group <NUM> comprises a recycling chamber <NUM> in which the mixing and shredding element <NUM> is housed. The scarification chamber <NUM> and the recycling chamber <NUM> are directly communicating with each other by means of a conglomerate passage opening <NUM> suitable for being opened or closed by means of the interception device <NUM>.

According to one embodiment, shown for example in <FIG>, the assembly <NUM> comprises a scarification group frame <NUM>, which at least partially defines the scarification chamber <NUM>, and a recycling group frame <NUM>, which is disconnected but fixed to the scarification group <NUM> and which at least partially defines the recycling chamber <NUM>.

Said scarification group <NUM> and said recycling group frame <NUM>, when joined, preferably form the assembly body <NUM>'. Preferably, the scarification group <NUM> is therefore joined to the recycling group frame <NUM>.

According to one embodiment, shown for example in <FIG>, the scarification group frame <NUM> and the recycling group frame <NUM> are a single main frame which forms the assembly body <NUM>'. Preferably, in this embodiment, the single main frame is a single piece which supports the excavation tool <NUM> and the shredding and mixing element <NUM>.

Preferably, the conglomerate passage opening <NUM> is made in the scarification group frame <NUM> or in the recycling group frame <NUM>.

According to one embodiment, the interception device <NUM> comprises a bulkhead <NUM>' translatable with respect to the scarification group frame <NUM> and/or to the recycling group frame <NUM> to determine the opening or the partial or total closing of the conglomerate passage opening <NUM>.

In the embodiment wherein the interception device <NUM> is suitable for maintaining itself in support against the base of the road surface being worked and for being passively guided in translation along a translation direction Z in order to follow the course of the base of the road surface being worked, the bulkhead <NUM>' is suitable for maintaining itself in support on the road surface, closing or opening the conglomerate passage opening <NUM> in a variable manner according to the course of the road surface and the working depth.

In general, the bulkhead <NUM>' preferably functions as a bulkhead for scraping the base of the road surface and prevents the direct passage of the milled conglomerate C below the sieving element <NUM> from occurring without first passing through the recycling group <NUM> when the conglomerate passage opening <NUM> is at least partially open.

When, instead, the bulkhead <NUM>' is in a configuration in which it totally closes the conglomerate passage opening <NUM> (as for example shown in <FIG>), in this case the bulkhead <NUM>' then prevents the passage of the regenerated conglomerate material CR toward the second region R, i.e., toward the recycling group <NUM>.

According to one embodiment, the interception device <NUM> comprises a bulkhead movement group <NUM>, for example one or more hydraulic or electric cylinders, connected to the bulkhead <NUM>' and to the scarification group frame <NUM> and/or to the recycling group frame <NUM>. Said bulkhead movement group <NUM> is suitable for translating the bulkhead <NUM>' along the vertical direction of translation Z substantially perpendicular with respect to the plane of the road pavement P.

Preferably, in any variant of the interception device, in the scarification group frame <NUM> and/or on the recycling group frame <NUM> translation guides are formed which are suitable for housing the bulkhead <NUM>' in translation along the direction of translation Z.

According to one advantageous embodiment, the assembly <NUM> comprises a dosing unit (not shown in the figures) suitable for adjusting the amount of water and/or regenerating fluid to be dispensed via the water and/or regenerating fluid dispensing device <NUM>.

Preferably, the water and/or regenerating fluid dispensing device <NUM> comprises one or more dispensing nozzles having a dispensing mouth which directly faces into the scarification chamber <NUM> and/or into the recycling chamber <NUM>.

The dosing unit preferably comprises means for storing water and regenerating fluid and pumping means for dispensing the water or regenerating fluid from the storage means to the water and/or regenerating fluid dispensing device.

It is clear that the dosing unit may be installed on the assembly <NUM> or may be relocated on the operating machine <NUM> and comprise fluidic means for supplying the regenerating fluid or water toward the water and/or regenerating fluid dispensing device <NUM>.

According to one embodiment, the cold scarification and recycling assembly <NUM> comprises a speed detector device <NUM>. Optionally, the cold scarification and recycling assembly <NUM> comprises a depth detector device.

The speed detector device <NUM> is operatively connected to the dosing unit and suitable for detecting the advancement speed of the cold scarification and recycling assembly along the working surface S. In this variant, the dosing unit is suitable for adjusting the amount of water and/or regenerating fluid to be dispensed according to the advancement speed detected by the speed detector device <NUM>.

According to one embodiment, the depth detector device is operatively connected to a dosing unit and is suitable for detecting the scarification depth D' of the road pavement P performed by the scarification group <NUM> with respect to the plane of the road pavement P. In this variant, the dosing unit is suitable for adjusting the amount of water and/or regenerating fluid to be dispensed according to the depth detected by the depth detector device <NUM>.

It is clear that the cold scarification and recycling assembly <NUM> may comprise only the speed detector device <NUM>, or both the speed detector device <NUM> and the depth detector device.

According to one embodiment, the speed detector device <NUM> comprises, for example, a speed detector such as a GPS, or an electronic device for detecting the linear advancement speed, or similar.

According to one embodiment, the depth detector device comprises, for example, a distance detector, such as a laser, optic or ultrasound detector or a mechanical distance detector.

According to one embodiment variant, the speed detector device <NUM> comprises a wheel <NUM> and a wheel support group <NUM> suitable for supporting the wheel in a manner rotatable about a wheel rotation axis X". The wheel support group <NUM> is suitable for positioning the wheel in a rearward configuration A, in which the wheel is spaced apart with respect to the level of the road pavement P, and a working configuration W, in which the wheel is in contact with the road pavement P during the advancement of the cold scarification and recycling assembly <NUM>.

Preferably, the speed detector device <NUM> comprises a wheel rotation speed sensor, for example an electronic encoder.

According to one embodiment, the wheel support group <NUM> comprises a wheel support arm <NUM>.

Optionally, the wheel support group <NUM> comprises arm movement drive means.

The wheel support arm <NUM> is rotatable about an arm rotation axis X‴ which is parallel and spaced apart with respect to the wheel axis of rotation X''. In this way, for example, the wheel support arm <NUM> is configurable with its main extension axis parallel to the level of the road pavement P when the assembly is in operation or perpendicular (i.e., vertical) with respect to the level of the road pavement P when it is not in operation or when it is not necessary to measure the advancement speed of the assembly <NUM>, as shown, for example, in <FIG>, in the first scarification step (milling) or in <FIG>.

Preferably, the wheel support group <NUM> further comprises an angular position sensor suitable for determining the milling depth of the cold scarification and recycling assembly <NUM> as a function of the angular position of the wheel support arm <NUM> (functioning, therefore, as a depth detector device).

According to one preferred embodiment, the sieving element <NUM> is a perforated wall or a grid having sieve openings and arranged below the mixing and shredding element <NUM>, in the vertical direction perpendicular to the level of the road pavement P. Therefore, the sieving element is the last element that the regenerated conglomerate CR encounters before being released on the working surface S of the road pavement P.

According to one embodiment, the sieving element <NUM> is a perforated wall in the form of a cylindrical or semi-cylindrical sector that is fixed to and integral with the recycling group frame <NUM>.

According to one embodiment, the sieving element <NUM> is a wall comprising sieve openings having a section of a size recordable via manual control or via an electrical or hydraulic or mechanical actuator operatively connected to the sieving element <NUM>. For example, according to one embodiment, the scarification and recycling assembly comprises a second wall in relative movement with respect to the sieving element <NUM> so as to reduce or expand the section of the sieve openings. For example, the second wall and the sieving element <NUM> are two walls, preferably in the form of a cylindrical or semi-cylindrical sector, slidable in relation to one another for opening or closing the sieve openings.

Preferably, the second wall in relative movement with respect to the sieving element <NUM> opens and closes windows in order to increase or decrease the dimension of the material to be discharged or close the discharge off completely.

It is clear that a further object of the present invention is an operating machine <NUM> comprising a cold scarification and recycling assembly <NUM> described in the preceding paragraphs, for example preferably mounted on the rear of a tractor or on the loader arm of a mini-loader.

Said operating machine <NUM> is preferably provided with at least one fluidic power take-off <NUM> for powering the drive means <NUM>, <NUM> and/or the bulkhead movement group <NUM> and/or the arm movement drive means.

According to one embodiment, the operating machine <NUM> is preferably provided with at least one electrical power take-off for powering the drive means <NUM>, <NUM> and/or the bulkhead movement group <NUM> and/or the arm movement drive means.

According to one embodiment, the operating machine <NUM> is preferably provided with at least one mechanical power take-off <NUM> for powering the drive means <NUM>, <NUM> and/or the bulkhead movement group <NUM> and/or the arm movement drive means.

Furthermore, another object of the present invention is a method for restoring a road surface which utilizes an operating machine <NUM> to which a cold scarification and recycling assembly <NUM> as previously described is attached. The method in its most general embodiment, shown for example in <FIG> or <FIG> or <FIG>, comprises the following operational steps:.

Preferably, the method further comprises the operational step of:.

g) smoothing and compacting the regenerated milled conglomerate CR (<FIG>).

A further embodiment of a method for restoring a road surface which utilizes an operating machine <NUM> to which a cold scarification and recycling assembly <NUM> as previously described is attached is shown, for example, in the sequence of figures from <NUM> to <NUM>. In this embodiment, the method for restoring a road surface comprises the operational steps of:.

According to one embodiment, step c) involves the injection of water or, more generally, a liquid on the milled conglomerate being worked in the scarification chamber and/or in the recycling chamber <NUM>, for example in order to suppress the dust.

Preferably, in step c') or in step e), the injection of regenerating fluid and possibly water involves:.

According to one embodiment, the method for restoring a road surface, after step c) or after step c'), comprises the optional step of:.

h) moving the scarification and recycling assembly <NUM> on the damaged road surface or on the milled conglomerate C arranged on the working surface S or on the regenerated milled conglomerate CR arranged on the working surface S with the interception device <NUM> in the closed configuration;.

Said step h) is shown, for example, in <FIG> in an exemplary embodiment wherein the scarification and recycling assembly <NUM> is moved on the regenerated milled conglomerate CR following the execution of the preceding step e), or of the preceding step c') or of the preceding step d). In said variant, step h) allows an adequate remixing of the regenerated milled conglomerate CR, for example without having to further crush the conglomerate or reduce the size of the pieces being worked in the recycling group <NUM>.

Innovatively, the present invention is suitable for overcoming the drawbacks related to the prior art.

More precisely, the cold scarification and recycling assembly of the present invention makes it possible to restore a damaged road surface without the need for removing and carrying the road surface material elsewhere, but by regenerating the same removed material and redepositing it anew on the road surface.

This makes it possible to immediately repair the road surface, completely on site, without adding (or possibly with a minimum addition of) further conglomerate material. Consequently, a repair intervention requiring minimal times and at contained costs is achieved.

Furthermore, thanks to the fact that the conglomerate material is recycled, it is not necessary to store such material and dispose of it as special waste.

Additionally, compared to the cold regeneration machines of the prior art, the assembly according to the present invention turns out to be particularly compact and suitable for the specific purpose of repairing small plots. In fact, the assembly according to the present invention does not require bulky and non-self-propelled conglomerate regeneration machines, but executes the operation of scarification and regeneration and placement of the conglomerate in an integrated manner.

According to a further advantage, the fact that the assembly according to the present invention is suitable for being directly connected to a mobile arm of an operating machine and, preferably, the fact that it is configured both for being pulled and for being pushed renders the use of the assembly itself particularly versatile and flexible. In fact, is easily connectable to the majority of known operating machines and does not require the application of sensitive modifications to the design of the known operating machines.

Furthermore, said possibility allows to adapt the known operating machines for the execution of activities of scarification and recycling of the road pavement without requiring the predisposition of a self-propelled machine dedicated for the application. Therefore, this provides great potential for converting the already existing operating machines.

In an advantageous manner, the possibility of metering the amount of regenerating fluid and water in line (i.e., during the advancement of the assembly) and in a controlled manner during the advancement of the assembly makes it possible to render the regeneration procedure more effective and efficient. In fact, the amount of regenerating fluid is adaptable as a function of the advancement speed and the type of conglomerate involved.

Furthermore, in an advantageous manner, thanks to the presence of the interception device in the form of a bulkhead, it is possible to integrate the two functions of scarification and recycling in a simple and compact manner in a single assembly, which is transportable and connectable to an operating machine of small dimensions, thereby allowing repair operations of small plots that cannot be realized with the cold regeneration machines of the prior art (which are bulky and onerous in terms of economic and time resources).
