Definitions
- a self-propelling machine used to lay down materials for paving roads, airports, cycle tracks, courtyards, car-parks, etc. is commonly called a "road-paver-finisher”.
- the materials to be laid down (generally mineral aggregates mixed with bitumen, asphalt, or other hydrocarbon binders, or cement or other hydraulic binders) must be spread so as to form a levelled, compact layer.
- the paver-finisher in general is essentially composed of a tractor unit to impart the forward motion and a screed or leveling unit, often provided with beating or vibrating tamping members, to form the finished "carpet".
- the road paver-finisher member responsible for performing this function is commonly called the “screed” or “leveling plate” or “leveling beam”; from now on we will simply call it a “screed”.
- the screeds of known type can be divided into two classes, namely "semi-floating" screeds and "full-floating" screeds.
- Full-floating screeds can in turn be divided into two classes: those mounted rigidly on the tractor unit (and which use the tractor itself as the reference member) and those towed by the tractor which use their own reference members to set the thickness of the carpet to be laid down.
- a road paver-finisher of the most common type operating on the semi-floating principle is formed by the combination of two main units: the tractor unit and the semi-floating screed unit.
- the screed consists of a more or less complicated transverse member that is pulled by the tractor unit by means of two long longitudinal arms pivotally mounted about halfway along the tractor unit.
- transverse member engages with the material to be laid on the old road surface, smoothing and leveling it to form an even carpet.
- the tractor unit forming the main body of the paver also comprises many members that are not directly connected with the function of imparting forward motion to the machine and pulling the screed.
- tractor unit receives the material from dump trucks and storing it; organizing the longitudinal and transverse flow of said material in order to feed it, evenly distributed, in front of the screed.
- the longitudinal and transverse flow of the material is organized by one or more conveyor belts and augers that provide a suitable flow of material and convey it toward the screed.
- augers In both semi-floating and full-floating screeds the augers' main function is to distribute the material evenly crosswise in front of the screed. The ideal would be if these augers could always be positioned vertically according to the actual height of the bottom of the screed. For this purpose the augers can easily be mounted on the screed; in this way, however, all the reaction forces that the augers undergo because of their interaction with the material are transmitted to the screed on which they are integrally mounted.
- Document DE 42 29 465 A1 discloses a road paver-finisher provided with a screed of the semi-floating type, comprising screed arms mounted on the paver-finisher tractor, and in front of which screed an auger system operates for transverse distribution of the mix to be laid, the augers being mounted on a sub-frame provided with arms, the front ends of the arms of the subframe being mounted on the tractor at their centers of rotation, the up and down movement of the augers taking place as a rotary movement around their centers of rotation by means of actuators mounted on the tractor that engage on the sub-frame.
- An aim of the present invention is to overcome the drawbacks of the prior art, and in particular to provide a semi-floating-screed paver-finisher in which the auger or augers can follow the screed position vertically without transmitting forces to said screed that might affect its action.
- the invention relates to a road paver-finisher equipped with a screed or screed unit of the semi-floating type in front of which operates a system of augers for transverse distribution of the mix to be laid down.
- the augers are driven by geared motors and drives are mounted on a subframe equipped with arms that remain approximately parallel to the arms of the screed, the front ends of the under-frame arms being mounted on the tractor at their centers of rotation, these latter always being situated in a position very close to the centers of rotation and traction of the screed arm front ends, the up and down movement of the augers taking place as a movement of rotation around the centers by means of actuators, for example hydraulic pistons, mounted on the tractor, that engage on the sub-frame or on the arms.
- actuators for example hydraulic pistons
- the invention makes it possible to achieve the above mentioned aims, and particularly to regulate the position of the augers vertically without affecting the action of the screed.
- a known paver-finisher as illustrated in FIG. 1, 2 and 3, comprises a tractor unit 10 and a screed unit 11.
- the tractor unit 10 comprises a main frame 12, a hopper 13 intended to receive the material from dump trucks, one or more conveyor belts 14 and augers 15 that produce a suitable flow of material and convey it towards screed 11.
- the main frame 12 of the tractor unit 10 is provided with traction wheels 12' and steering wheels 12" (or crawlers 12''') that cause the translation of the whole machine.
- the screed 11 is provided with traction or towing arms 16 pivotally mounted at their end 17 on the main frame 12 of the tractor unit 10.
- the wheels 12' and 12" of the traction unit 10 actually follow the pre-existing undulations of the ground and thus impart an undulating and jerking movement to the tractor unit which, as far as possible, should not be transmitted to the screed 11.
- the two wheels 12" that lie approximately on the same vertical-longitudinal plane are mounted on a floating arm 12bis called a "cantilever arm” mounted pivotally on the pivot 12ter integral with the main frame 12.
- the position of the pivot 18 is usually chosen about half-way along the wheel-base of the tractor unit 10.
- FIG 4 shows a schematic vertical section of a road surface on which a paver-finisher provided with the semi-floating screed is laying down a carpet of material.
- the pre-existing road surface 20 has undulations that are to be eliminated or at least smoothed by laying on top a carpet 21 of a suitably variable thickness so that where there is a bump 22 a thinner carpet layer is laid.
- the semi-floating screed 11 allows this compensation of thicknesses and consequently “smoothing" of the pre-existing undulations to be achieved without having to resort to complicated automatic leveling systems.
- FIG. 5 shows a schematic perspective of a slip-form paver-finisher mounted on three means of locomotion 24.
- the material 25 is contained in a hopper 26 the side walls of which also perform the function of slip forms to "extrude” the final layer of material 27 that is laid down by the paver-finisher.
- the devices 23 schematically represent the mechanical-hydraulic systems that regulate the vertical position of the means of locomotion relative to the main body of the whole machine and thus determine the height of the hopper 26 moment by moment with respect to the pre-existing road surface and ultimately establish the thickness of the layer 27 of material to be laid moment by moment.
- a paver-finisher like that illustrated in FIG. 5 is therefore provided with a full-floating screed mounted integral to the tractor unit of the paver-finisher itself.
- paver-finishers with a full-floating screed towed by the tractor unit have also been placed on the market, though somewhat rarely.
- the full-floating screed determines its own vertical position (and consequently the thickness of the layer to be laid) making use of its own reference members which can be soles, slides, wheels or other means that rest on the pre-existing road surface.
- the towed full-floating screed must therefore comprise internal adjustment means that allow the transverse member (on which the thickness of the layer to be laid down depends) to be positioned at a desired pre-set height, in order to determine precisely the thickness of the spread layer.
- the present invention in fact relates to a paver-finisher with a series of devices and arrangements that allows better control of the interaction between the semi-floating screed unit 11 and the auger unit 15, which produces a leveling action like that illustrated in the diagram in FIG. 4.
- the augers 15 have the main function of evenly spreading the material transversely in front of the screed 11.
- the paver-finisher 100 shown in FIG. 6, unlike those that appear in the preceding figures is of the "semi-crawler" type where the function of the traction wheels 12' (of FIG. 2 and 3) is performed by a crawler carriage 12'''; however, it could also be of the wheeled type.
- two hydraulic pistons 40 mounted on the tractor 10 engage on the screed 11 (or, as shown in FIG. 6, on the arms 16) to allow the whole screed to be raised at the end of the job, facilitating rapid traverse and/or transportation of the whole machine on a truck.
- the pistons 40 "idle”, which means there is no oil pressure inside them, allowing the screed to "float” freely following its own self-leveling movement, that is riding on the spread material following the pull of the tractor 10 exerted by means of the arms 16.
- the (average) thickness of the layer of material to be laid is set by the operator and/or by automatic leveling systems not described herein, simply by raising or lowering the traction point 18 by means of a hydraulic piston 18'.
- the augers 15, if mounted integrally on the tractor often come to be in a very cumbersome position, suffering knocks and damage.
- the augers 15 are mounted on the tractor so that their height can be adjusted, but their movement never parallels that of the screed 11, adjustment is awkward, must generally be done with the machine at a standstill and in any case it is never directly controlled by the movement of the screed.
- the augers 15 driven by a geared motor unit 30 by means of a drive 31 are mounted on a subframe 32 also provided with arms 34, the front ends 35 of which are mounted on the tractor 10 at their centers of rotation 36.
- the front ends 35 of the arms 34 are connected with articulated joints to the front ends 17 of the arms 16 of the screed 11, for example making use of link rods 37 so that when their vertical position is changed by the piston 18' the vertical position of the front ends 35 of the arms 34 is changed accordingly.
- a simple sensor 50 measures the relative vertical position between the screed 11 and the subframe 32 (in the case in FIG. 6, between the arms 16 and the arms 34) and transmits appropriate signals to the hydraulic circuit that controls the pistons 40' in order to ensure that the augers 15 always follow all the changes in height made by the screed 11 during the laying work.
- the sensor 50 is also provided with adjustment members of a known type that make it possible to pre-set the desired height difference between the augers 15 and the screed 11 that is to be maintained constantly.
- FIG. 7 is a perspective view of the screed unit and the auger unit in an embodiment according to the present invention, imagining the whole tractor unit 10 displaced forwards. Only the parts 51 and 52 of the tractor 10 have been left visible as these are the parts through which connection between the tractor 10 and the screed units 11 and augers 15 takes place.
- FIG. 7 is also useful because it provides a view of the supports 33 that support the axle of the augers 15 in an intermediate position when the geared motor units 30 and relative drives 31 are moved outwards to achieve the maximum transverse extension of the augers 15 themselves.
- FIG. 8 Another embodiment of the present invention is shown in FIG. 8, in which the rotary motion is imparted to the two augers by means of a system of two geared motors and two drives virtually fused into a single central unit according to a configuration similar to that applied in more conventional paver-finishers.
- the present invention allows the augers to be given a movement that is always parallel to the screed movement, therefore keeping the auger axle at a constant horizontal distance from the front surface of the screed and allowing its height relative to said screed to be adjusted automatically.
