Definitions

  • the invention relates to a screed arrangement for a road paver according to the preamble of claim 1.
  • Pavers for paving concrete or bituminous paving mix usually have a screed assembly that is towed behind the paver. With this screed arrangement, the distributed paving mix is smoothed and already significantly pre-compacted before the final compaction takes place, for example by means of a roller that follows the paver. It is particularly advantageous if the screed has a variable length in a direction transverse to the paving direction of travel of the paver in order to be able to achieve different paving widths.
  • the EP 2 201 176 B1 discloses a leveling screed with extendable sectors one behind the other, which are firmly connected to fixed sectors.
  • the generic one 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 direction of installation travel, which can be extended and retracted transversely to the direction of installation travel in a common adjustment plane. Such a plank arrangement is also known in specialist circles as a “front mounted screed”. Because the two extendable screeds are each directly adjacent to the front of the base screed, a material deflector member that is adjustable relative thereto is provided on the base screed and/or on at least one of the extendable screeds in order to prevent the installation material from becoming jammed between the two extendable screeds when they move towards each other can be 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 paver in order to eliminate the above-mentioned disadvantages.
  • the invention relates to a screed arrangement for a road paver with a base 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 base screed in a pulling direction of the screed arrangement and being movable transversely to the pulling direction relative to the base screed, with at least one of the two extending screeds has a material deflecting member which is configured to displace installation material in the direction of a central axis (M) of the screed arrangement to a pulling direction of the screed arrangement when the extending screed is stationary relative to the base screed, the first extending screed having the material deflecting member, wherein 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 plank has a shielding element, or a deflector plate or shielding plate.
  • the shielding element can be understood in the broadest sense as a wall.
  • the shielding element is configured to prevent the installation material lying in front of the base screed from shifting laterally beyond the width of the base screed when the first extending screed is retracted.
  • the pulling direction of the screed arrangement is the direction in which the screed arrangement is pulled by a paver or its tractor during operation, i.e. it corresponds to the direction of travel of the paver.
  • 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 base screed. As a result, the maximum installation width of the screed arrangement according to the invention can be approximately three times the working width of the base screed when the two extending screeds are in the maximum extended position, and this without the addition of additional widening parts. This speeds up the adjustment of the installation width, especially on site, as there is no need to add, remove or adjust the widening parts.
  • the extending screeds arranged one behind the other in the direction of pull is that this arrangement means that very little or even no installation material is clamped between the two extending screeds because they are not moved towards each other in the same adjustment plane when retracting. Furthermore, the material deflector member of the first extending screed enables the installation material to be displaced in the direction of a central axis to a pulling direction of the screed arrangement, so that when this extending screed is retracted, no installation material is trapped between the extending screed and the shielding element of the base screed.
  • the shielding element can prevent the paving material lying in front of the base screed from being pushed beyond the width of the base screed onto the subsoil or onto a covering that has already been pre-compacted by the extending screed working at the front
  • the screed arrangement has a central axis, the central axis being parallel to the pulling direction, each extending screed having an inside and an outside, the inside being closer to the central axis in an extended position of the respective extending screed than the outside, whereby this Material rejection member 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 larger installation widths compared to a known screed arrangement in which the extending screeds are half the size of the base screed.
  • the shielding element is present as a plate which is attached laterally to the base board body of the base board and extends beyond the base board body in the pulling direction. This means that the first extending screed can be extended and retracted across its entire working width.
  • the shielding element is designed to be essentially the same height 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 removable in the pulling direction relative to the base plank. This allows the shielding element to be adjusted in view of the structural design of the material rejection member.
  • a removable shielding element is advantageous for cleaning and, if necessary, transport purposes.
  • the shielding element or a part formed thereon can expediently be designed to be pivotable relative to the base plank and/or displaceable transversely to the pulling direction. In this way, the paving material can be moved inward from an outer area in front of the base screed towards a central axis of the screed arrangement running in the pulling direction.
  • the shielding element is part of a side slider Basic plank formed.
  • a side shifter prevents the installation 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 slide of the base pile.
  • 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. This would allow the installation material to be moved when the extending screed is retracted in such a way that it is not trapped between the two extending screeds.
  • the two extending screeds can 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 in front of it.
  • the shielding element is designed as an integral part of a side slide of the base pile.
  • Jamming or sticking of the installation material can be reduced particularly effectively by the fact that the material rejection member and/or the shielding element can be heated.
  • the second extending screed also has a material rejection member configured for relocating paving material. It is advantageous if the first extending screed has a shielding element for the material rejection member of the second extending screed.
  • the structure described above, regarding the shielding element of the base screed and the material deflector member of the first extending screed, is repeated in this variant, at least from a functional point of view. Basically, both the shielding elements and the material deflector members can be designed in a comparable structural manner.
  • a side slide 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.
  • the plank arrangement is particularly stable if the material deflector member is rigidly attached to the one or more respective extending screeds are formed.
  • the material rejection 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.
  • the material deflector member does not influence the installation process.
  • an additional working width is available for extending the extending screeds.
  • the positioning of the material rejection member at an angle to the pulling direction ensures that the paving mix is displaced to a central axis of the screed arrangement when the extending screeds are retracted.
  • the rejection of the paving material i.e.
  • the displacement of the paving material in the direction of the central axis of the screed arrangement becomes particularly effective when the material rejection member is in the active position at an angle of 30° to 55° relative to the pulling direction.
  • the material deflector members can be pivoted about a hinge. It is also possible for a rear side of the material deflector members to be coupled to the base beam via a sliding fit so that the rear side can be displaced along the base beam.
  • the rejection of installation material is particularly efficient if the material rejection member is designed in the form of a plow structure. This allows the paving material to be pushed forward when the extending screed(s) retracts.
  • the rejection of installation material is particularly efficient if the material rejection member extends in plan view at an angle other than zero to the pulling direction, preferably at an angle of 30° to 60°.
  • the screed arrangement has a screed control station on the side of the base screed, facing the material rejection member of the first extending screed. From here, a screed operator can easily monitor the material deflector member, especially its plowing function while the extending screed is being retracted.
  • the invention relates to a road paver with a screed arrangement of the type described above.
  • a road paver in particular the screed arrangement used on it, enables the paving width to be adjusted quickly and precisely without clamping a mix template between the base screed and the extending screed.
  • the plank arrangement offers the practical advantage that it can be adjusted quickly and precisely for leveling purposes, in particular for height and/or cross slope leveling is. This is particularly facilitated by the broadly adjustable plank structure of the plank arrangement according to the invention, which is, however, composed of a few modules.
  • Fig. 1 shows a side view of a paver 1. Its paving direction is indicated by E.
  • the paver 1 includes a tractor 2. This has a mix bunker 3 into which, for example, asphalt mix can be filled. This mix or paving material can be transported to the rear end of the tractor 2 by a conveyor system (not shown) against the paving direction E of the paver 1. There it can be distributed in front of a screed arrangement 4 of the paver 1 transversely to the paving direction E.
