Definitions

  • the invention relates to a screed arrangement for a road finisher according to the preamble of claim 1.
  • Pavers for laying concrete or bituminous paving mix usually have a screed assembly that is towed behind the paver. With this arrangement of screeds, the distributed paving mix is smoothed and already considerably pre-compacted before the final compaction takes place, for example by means of a roller driving behind the paver. It is particularly favorable if the screed has a variable length in a direction transverse to the paving travel direction of the road finisher in order to be able to achieve different paving widths.
  • the EP 2 201 176 B1 discloses a leveling screed with telescopic sectors lying one behind the other, which are firmly connected to fixed sectors.
  • the generic EP 2 395 151 A1 discloses a screed arrangement with a base screed and two extending screeds arranged in front of the base screed in the paving direction of travel, which can be extended and retracted transversely to the paving direction of travel in a common adjustment plane. Such a plank arrangement is also called "front mounted screed" in specialist circles.
  • a material deflector element that can be adjusted relative thereto is provided on the base screed and/or on at least one of the extending screeds in order to prevent the paving material from becoming trapped between the two extending screeds when they approach one another are moved and a certain distance between the two extending screeds is not reached.
  • the object of the invention is to provide a screed arrangement for a road finisher in order to eliminate the disadvantages mentioned above.
  • the invention relates to a screed arrangement for a road finisher with a basic screed, a first extending screed and a second extending screed, the first extending screed and the second extending screed being arranged in front of the basic screed in a pulling direction of the screed arrangement and being movable relative to the basic screed transversely to the pulling direction, with at least one of the two extending screeds has a material deflecting member configured to displace paving material toward a central axis (M) to a pull direction of the screed assembly when the extending screed is stationary relative to the base screed, the first extending screed having the material deflecting member, the second Extending screed is positioned further away from the base screed in the pulling direction of the screed arrangement.
  • M central axis
  • the base screed has a shielding element or a deflector plate or shielding plate for the first extending screed.
  • the shielding element can be understood as a wall in the broadest sense.
  • the shielding element is configured to prevent the paving material lying in front of the base plank from being displaced laterally beyond the width of the base plank when the first extending screed is retracted.
  • the pulling direction of the screed arrangement is the direction in which the screed arrangement is pulled during operation by a road finisher or its tractor, i.e. it corresponds to the direction of travel of the road finisher.
  • One of the main advantages of the screed arrangement according to the invention is the high variability of the installation width. This is because the extending screeds arranged one behind the other in the pulling direction in the invention can each have essentially the same working width as the basic screed. As a result, the maximum installation width of the screed arrangement according to the invention can be about three times the working width of the basic screed when the two extending screeds are in a maximum extended position, and that without the addition of additional widening parts. This accelerates the adjustment of the pave width, especially on site, since there is no need to attach, remove or adjust the widening parts.
  • a further advantage of the extending screeds arranged one behind the other offset in the pulling direction is that this arrangement causes very little or even no paving material to be jammed between the two extending screeds because they are not moved towards one another in the same adjustment plane when they are retracted. Furthermore, the material deflecting member of the first extending screed allows the paving material to be shifted in the direction of a central axis to a pulling direction of the screed arrangement, so that no paving material is trapped between the extending screed and the shielding element of the base screed when this extending screed is retracted.
  • the shielding element can prevent the paving material in front of the basic screed from being pushed beyond the width of the basic screed onto the subsoil or onto a surface that has already been pre-compacted by means of the extending screed working at the front
  • the screed arrangement has a central axis, with the central axis being parallel to the pulling direction, with each extending screed having an inside and an outside, with the inside being closer to the central axis than the outside when the respective extending screed is in an extended position, with the Material deflector is arranged on the inside of the extending screed.
  • the base screed and the two extending screeds preferably have essentially the same working width.
  • the screed arrangement can achieve significantly greater installation widths in comparison to a known screed arrangement in which the extendable screeds are half the size of the basic screed.
  • the shielding element is present as a plate which is fastened laterally to the base plank body and extends beyond the base plank body in the pulling direction. This allows the first extending screed to be retracted and extended over its entire working width.
  • the paving material is prevented from falling out transversely to the pulling direction in a particularly efficient manner if the shielding element is designed essentially as high as the first extending screed and/or the shielding element extends in the pulling direction corresponding to a working depth of the first extending screed.
  • the shielding element is designed to be adjustable and/or detachable relative to the base plank in the pulling direction. As a result, the shielding element can be adjusted with regard to a constructive design of the material deflection element.
  • a demountable shielding element is advantageous for cleaning and possibly transport purposes.
  • the shielding element or a part formed on it can expediently be designed such that it can be pivoted relative to the base plank and/or displaced transversely to the pulling direction. In this way, the paving material can be moved inward from an outer area in front of the basic screed towards a central axis of the screed arrangement running in the pulling direction.
  • the shielding element is part of a side shifter Basic plank trained.
  • a side shifter prevents the paving material from falling out beyond a desired width. In addition to its actual function, it also acts as a shielding element.
  • the shielding element is arranged as a plate on a side shifter of the base plank.
  • This plate could be designed to be displaceable or pivotable relative to the side shifter in order to push paving material in the direction of the central axis of the screed arrangement.
  • paving material can be shifted in such a way that it is not jammed between the two extending screeds.
  • the two extending screeds could be retracted one after the other, i.e. the one positioned closer to the base screed first and at least temporarily offset by the extending screed that is in front of it.
  • the shielding element is designed as an integral part of a side shifter of the base plank.
  • Pinching or sticking of the built-in material can be reduced particularly effectively if the material deflecting element and/or the shielding element can be heated.
  • the second extending screed also has a material deflecting member configured for moving paving material. It is advantageous if the first extending screed has a shielding element for the material deflecting member of the second extending screed.
  • the construction described further above, relating to the shielding element of the base plank and the material deflector element of the first extending plank, is repeated in this variant, at least from a functional point of view. Basically, both the shielding elements and the material deflection members can be designed in a comparable structural manner.
  • a side shifter of the first extending screed which is arranged on an opposite side of the material deflecting member formed thereon, can act as a shielding element for the material deflecting member formed on the second extending screed.
  • a shielding element on the side shifter of the first extending screed that is adjustable, in particular pivotable or displaceable, relative to the side shifter formed thereon, in order to promote the shifting of the paving material in the direction of a central axis of the screed arrangement.
  • plank arrangement is particularly stable when the material deflector member is rigidly attached to the or the respective extending planks is formed.
  • the material deflecting member prefferably be adjustable between an inactive position, in which it extends parallel to the pulling direction, and an active position, in which it extends at an angle to the pulling direction. In the inactive position, the material deflection element therefore does not affect the installation process. Furthermore, in the inactive position, an additional working width is available for extending the extending screeds. In the active position, the setting of the material deflector member at an angle to the direction of pull ensures that the paving mix is displaced to a central axis of the screed arrangement when the extending screeds are retracted. The deflection of the paving material, i.e.
  • the displacement of the paving material in the direction of the central axis of the screed arrangement is particularly effective when the material deflecting member is in the active position at an angle of 30° to 55° relative to the pulling direction.
  • the material deflection members can be pivotable about a hinge. It is also possible that a rear side of the material deflecting members is coupled to the base plank via a sliding fit so that the rear side can be slid along the base plank.
  • the deflection of paving material is particularly efficient if the material deflection element is designed in the form of a plow structure. This allows the paving material to be pushed forwards when the extending screed(s) is/are retracting.
  • the deflection of built-in material is particularly efficient if the material deflection element extends at an angle that is not equal to zero to the direction of pull, preferably at an angle of 30° to 60°.
  • the screed arrangement has a screed operator's station on the side of the base screed, facing the material deflector element of the first extending screed. From here, a screed operator can monitor the material deflector element, in particular its plowing function, while the extending screed is being retracted.
  • the invention relates to a road finisher with a screed arrangement of the type described above.
  • a road finisher in particular the screed arrangement used on it, enables the paving width to be adjusted quickly and precisely without jamming a mixed material template between the basic screed and the extending screed.
  • the screed arrangement offers the practice-relevant advantage that it can be adjusted quickly and precisely for leveling purposes, in particular for leveling the height and/or cross slope is. This is favored above all by the broadly adjustable screed structure of the screed arrangement according to the invention, although composed of few modules.
  • the road finisher 1 shows a side view of a road finisher 1. Its paving direction of travel is indicated by E.
  • the road finisher 1 includes a tractor 2. This has a mix bunker 3, into which, for example, asphalt mix can be filled.

There it can be distributed transversely to the paving direction E in front of a screed arrangement 4 of the road finisher 1 .
  • the screed arrangement 4 can be mounted on the towing vehicle 2 so that it can be leveled by support arms 20 .
  • the plank arrangement 2 is towed behind the tractor 2 of the road finisher 1 in the installation travel direction E.
  • a transverse distribution device 18 is located between the tractor 2 of the road finisher 1 and the screed arrangement 4 towed thereon (see FIG figure 2 ), for example two transverse distribution screws, to spread the paving material to be processed over the paving width in front of the screed arrangement 4.

  • the pulling direction Z of the screed arrangement 4 corresponds to the paving travel direction E of the road finisher 1.
  • the first extending screed 5 is positioned closer to the base screed 7 in the pulling direction Z.
  • the second extending screed 6 is positioned further away from the base screed 7 in the pulling direction Z than the first extending screed 5. Consequently, the first extending screed 5 and the second extending screed 6 are arranged one behind the other in the pulling direction Z, i.e.
