Definitions

  • the invention relates to a channel plate of a road finisher.
  • a paver is used for the installation of bound and unbound mixes for the production of surface fortifications, see in particular roads.
  • the corresponding screw conveyors or worm spacers are mounted with channel plates.
  • Such channel plates are mounted in the direction of travel in front of a corresponding worm shaft on a worm conveyor frame part or directly on the chassis of the paver. They form together with a screed a so-called snail trough.
  • the channel plates require a minimum distance to the ground or plane in order to avoid collisions with this. For larger installation thicknesses, the distance of the channel plates to the planum is increased by a screw or chassis height adjustment.
  • the invention has for its object to prevent such flow of mix in the direction of travel forward and at the same time to improve the efficiency of the screw conveyor by a geometrically defined screw trough is formed.
  • a channel plate is proposed with the features of claim 1.
  • This channel plate is characterized in particular by the fact that a channel plate extension is arranged adjustable on the channel plate, in particular in the direction Planum. This prevents mixing material from flowing out of the screw space under the channel plates in the direction of travel to the front.
  • a geometrically defined screw trough is formed by this channel plate extension between the screw conveyor and the channel plate.
  • the adjustability of the channel plate extension ensures that, during installation, a flow of material in the direction of travel is certainly reduced to the front, but that a required ground clearance for the paver during transport travel is not undershot.
  • the channel plate extension is designed, for example, as a flap extension pivotably mounted on the channel plate. That is, the flap extension is pivotable so that, for example, depending on the distance of the channel plates to planum accordingly a flow out of mix from the screw space is prevented. At the same time the required ground clearance for the paver can be adjusted during transport.
  • the flap extension can be mounted pivotably substantially at the lower end of the channel plate. This results in a substantially uniform surface of the channel plate with corresponding flap extension. There is also the possibility that the flap extension is mounted pivotably spaced from the lower end of the channel plate.
  • a pivot axis connects channel plate and flap extension. This may extend along the lower end of the channel plate.
  • the flap extension can be connected via an adjustable hinge mechanism, in particular with a rear side of the channel plate.
  • Such a hinge mechanism can also be operated electrically or hydraulically.
  • the hinge mechanism comprises a link rod and an articulation flange projecting from the flap extension, to which the link rod is pivotably mounted. By appropriate actuation of the articulated rod can then be arranged on the Anlenkflansch the flap extension in different inclination positions relative to the channel plate.
  • the articulated rod can be fixed to a retaining bracket projecting from a rear side of the channel plate in at least one folding and one unfolding position.
  • the flap extension In the Einklapp ein the flap extension is pivoted back, so that essentially only the channel plate interacts with the screw conveyor. In the unfolded position, the flap extension supplements the channel plate.
  • the flap extension In the unfolded position, the flap extension supplements the channel plate.
  • the headband may have two spaced strap parts, between which the articulated rod is arranged. It may also prove to be beneficial if the articulated rod has a number of positioning holes, by means of which different relative positions of the articulated rod and headband are fixed.
  • the headband has at least two substantially mutually perpendicular to the back of the channel plate spaced Fixierö Maschinenspaare with which the positioning in the different relative positions are aligned and in which engages a fixing.
  • the fixing means serves to secure the various relative positions by engaging in Fixierö Maschinenspar and corresponding positioning holes.
  • the articulated rod can have a handle at its upper end.
  • the articulated rod has a lower in the direction Anlenkflansch inclined Anschabêt and one of this section in the direction of headband substantially vertically extending positioning.
  • the channel plate extension is designed as a sliding extension, with a substantially vertically displaceable sliding plate and a bearing part, wherein the bearing part is fastened to the channel plate.
  • the sliding plate is vertically displaceable relative to Lagerteill and accordingly arranged in different positions analogous to the folding or Ausklappwolfen.
  • the slide plate is lowered down in the direction Planum, while it is displaced vertically in Einklappwolf up to its maximum height position relative to the bearing part.
  • the bearing part may have a sliding guide for a slide bar connected to the sliding plate and / or guide slots for projecting from the sliding plate Verschiebevorsprünge.
  • the sliding guide By means of the sliding guide, the sliding plate is vertically adjustable via the sliding rod and by means of the guide slots, the sliding plate is guided over the protruding displacement projections relative to the bearing part and possibly fastened there.
  • the sliding plate has a Verstellvorsprung with threaded portion in which the sliding rod for height adjustment with a male threaded portion is engaged. That is, by turning the push rod is moved through the threaded engagement, the sliding plate further up or down relative to the bearing part.
  • the displacement projections may be formed as a sliding bolt and / or have a gland end portion.
  • nuts can be screwed onto this threaded end section in order to fix certain positions of the sliding plate relative to the bearing part.
  • the push bar can be mounted longitudinally displaceable in a bore formed in an upper cover edge of the sliding plate. Through this hole, a vertical guide of the sliding plate is relative to the push bar when it is rotated.
  • the channel plate extension may have a rubber scraper at its lower end or a lower end portion of the channel plate extension may be formed as such a rubber scraper. This means that this rubber scraper can avoid light collisions with the ground or planum and thus damage to the channel plate and in particular the adjustment of the corresponding flap extension is prevented.
  • FIG. 1 shows a perspective view obliquely from behind on a paver 1 with two lateral screw conveyors 2 to increase a working base width 3 to respective lateral working widths 4 and 5.
  • a paver 1 is substantially known, wherein the lateral screw conveyors 2, a number of channel plates 6 is assigned , These are arranged in the direction of travel in front of the screw conveyors 2 and are mounted on a corresponding traverse 7 or directly on the chassis 8 of the paver 1.
  • the channel plates together with the screw conveyors or a corresponding screed a so-called screw trough. This is intended to prevent mixed material from flowing out of the screw space under the channel plates in the direction of travel to the front, where it cools and worsens a paving result.
  • Corresponding channel plates 6 require a minimum distance to the ground or plane in order to avoid collisions with this. In addition, with larger installation thicknesses by a corresponding screw or Chassis Exercisenver ein the distance of both this and the channel plates 6 are increased to 9 Planum.
  • the corresponding channel plates 6 are arranged adjacent to an upper side of the subgrade 9 and releasably secured to the chassis 8 in the illustrated embodiment.
  • channel plate extensions 10 can be seen according to the invention FIG. 2 , be pivoted downwards in the direction Planum 9 or moved to prevent according to the increased distance with respect to a flow of mix from the screw space under the channel plates in the direction of travel forward.
  • the corresponding channel extensions 10 are extended at lower ends of the channel plates 6 in a corresponding Ausklappwolf 20.
  • FIG. 2 After FIG. 2 are the corresponding Kanalblechextensionen 10 designed as a flap extension 11, which are pivotally mounted at the lower ends 12 of the channel plates 6 by means of a corresponding pivot axis 13.
  • the pivot axis 13 is between the lower end 12 and an upper end of the flap extension 11 after FIG. 2 arranged.
  • FIGS. 1 and 2 are corresponding flap extensions 11 on the channel plate 6 in their different positions after FIGS. 1 and 2 shown in FIG. 3 in Einklapp ein 19 and in FIG. 4 in Ausklappleton 20, which also in FIG. 2 is shown.
  • FIG. 4 In particular, the pivot axis 13 between the lower end 12 of the channel plate 6 and the flap extension 11 is visible.
  • an articulation flange 17 On a rear side of the flap extension 11 there is arranged an articulation flange 17, which is connected to an inclined articulation section 29, which extends obliquely forwards and downwards in the direction of the articulation flange, of an articulated rod 16.
  • the corresponding articulated rod 16 is pivotally fixed to the Anlenkflansch.
  • a substantially vertical positioning portion 30 connects. This has a number of positioning holes 23, see Figures 3 and 4 which serve to fix the positioning section 30 on a retaining bracket 18, which protrudes from a rear side 15 of the channel plate 6.
  • This retaining bracket 18 has two spaced strap parts 21 and 22, between which the positioning portion 30 is displaceable.
  • a corresponding adjustment of the cap extension 11 takes place between, for example, the folding position 19 FIG. 3 or Ausklappwolf 20 after FIG. 4 , Corresponding intermediate positions are likewise possible, see the corresponding arrangement of the positioning openings 23.
  • bracket parts 21 and 22 have at least two fixing opening pairs 24 and 25 which are perpendicular to the back 15 of the channel plate 6 spaced from each other.
  • FIG. 3 becomes a first fixing hole pair 24, see also FIG. 4 , used for fixing the positioning section 30 by means of corresponding fixing means 26, while in FIG. 4 another fixing opening pair 25, see also FIG. 3 , serves for this fixation.
  • the corresponding fixing means 26 is for example a plug-in and fastenable in its insertion position bolt.
  • a handle 28 is fixed by means of the 16 different relative positions between the valve extension 11 and channel plate 6 are adjustable by a user by raising or lowering the articulated rod, see also the number of corresponding positioning holes 23 for such different relative positions ,
  • valve extensions 11 are at the lower ends, i. have at their free ends a rubber scraper, which can dodge in light collisions with the ground or planum and prevent damage to the hinge mechanism 14.
  • FIG. 5 and 6 is a further embodiment of a channel plate extension 10 in the form of a sliding extension 31 shown.
  • the sliding extension 31 includes, for example, a sliding plate 32 and a bearing part 33.
