  • the pivoting means comprises an actuating device which is articulated to save space at the upper end of the upper Abstreifschildes between a stationary part of the construction machine and the upper part of the scraper blade.
  • the actuator is therefore independent of lift cylinders of the scraper blade and can pivot the scraper blade about a first pivot axis when the scraper blade is out of engagement with the lateral supports.
  • the arrangement of the actuator a large swivel angle is possible because the scraper blade can be pivoted by 90 ° and more.
  • a small swivel radius is achieved because the lifting cylinder and thus the scraper blade even after completion of the actual lifting movement no further stroke for an additional pivotal movement must be prepared.
  • a low overall height of the pivoting device is realized in that the actuating device is preferably arranged horizontally.
  • the pivoting of the scraper blade is completely automatic, without manual operation is required.
  • the actuator may be arranged substantially orthogonal to the scraper blade.

  • the lower part of the scraper blade threads itself behind the two-sided sliding blocks.
  • the guides of the scraper blade are provided with chamfers or curves, wherein the sliding blocks themselves are rotatably mounted. This storage also causes the largest possible contact surface and thus low surface pressures that lead to low wear.
  • the protrusions are automatically retractable outwards to release the lower part of the scraper blade, when the lower part of the scraper blade is raised sufficiently.
  • the upper part of the scraper as seen in the direction of travel is supported on the sliding blocks and not the lower part.
  • the locking means are unlocked to release the upper part of the scraper blade when the lower part of the scraper blade is sufficiently or completely raised.
  • the lower part is lifted with a lifting device relative to the upper part until the upper part is out of engagement with the lateral holding devices.
  • the lower part of the scraper blade has an unlocking device which unlocks the locking means upon lifting of the lower part of the scraper blade after a predetermined stroke, so that the scraper blade is pivotable due to the unlocking.
  • the holding devices have on both sides of the scraper blade at least one parallel to the Fräswalzenachse in the direction of the orthogonal to the scraper blade extending side walls protruding shield-side projection as a first locking means which engages in a recess as a second locking means in the side walls when the scraper blade is in the operating position or not fully raised.
  • the locking bolt may be retractable inwardly to release the upper portion of the scraper blade when the lower portion of the scraper blade is sufficiently or fully raised.
  • the invention also relates to a construction machine, in particular a self-propelled road milling machine with a stripping device according to the aforementioned features.
  • the invention also relates to a construction machine, in particular a self-propelled road milling machine with the stripping device according to the invention.
  • Fig. 1 shows a self-propelled road milling machine 1 in the design of a large milling machine, in which a milling drum 6 between front and rear suspensions 2,3 is mounted with a Fräswalzenachse 5 in side walls 8 of the machine frame 4.
  • the milling drum 6 is surrounded by a roller box 7 fixed to the machine frame 4, which has a stripping device with a two-part scraper blade 10 at the rear end in the direction of travel.
  • the lower part 12 of the scraper blade 10 can slide during operation on the milled from the milling drum 6 bottom surface 9, wherein the lower part 12 of the scraper blade 10 is adjustable in height relative to the milling drum 6.
  • the stripping device with a two-part scraper blade 10 can of course also be used in other road milling machines of a different design.
  • a height-adjustable side plate 11 may additionally be provided as edge protection for the milling edge.
  • Fig.2 shows a first embodiment of a scraper with a two-part scraper blade 10, in which the upper part 14 of the scraper blade 10 is pivotally mounted at the upper end 16 pivotally about an axis parallel to the Fräswalzenachse 5 pivot axis 18.
  • the scraper blade 10 is in the operative position with lateral support means 20 in the side walls 8 in engagement, which hold the scraper blade 10 in a substantially orthogonal to the bottom surface 9 extending position.
  • lateral support means 20 in the side walls 8 in engagement, which hold the scraper blade 10 in a substantially orthogonal to the bottom surface 9 extending position.
  • Fig. 1 is the lower part 12 of the scraper blade 10 in engagement with sliding blocks 24 which are rotatably supported on both sides of the lower part 12 of the scraper blade 10 in the side walls 8.
  • the lower part 12 is provided at its vertical side edges 25 each with a sliding surface 26 which are in surface engagement with the sliding blocks 24.
  • the sliding blocks are cuboid, in particular square in cross-section and rotatably mounted in the side walls 8.
  • a pivoting device 30 can then pivot the scraper blade 10 about the pivot axis 18, wherein the pivoting device 30 is hinged to the upper end 16 of the upper part 14 with an actuator 34 consisting of a piston-cylinder unit.
  • the actuator 34 is on the machine side to a stationary part 32, e.g. hinged to the roller box 7 and extends substantially horizontally up to a hinge 36 at the upper end 16 of the upper part 14 of the scraper blade 10 so that the scraper blade 10 when applying a compressive force by the actuator 34 can be pivoted upwards by at least 90 ° ,
  • the scraper blade 10 Since the lower part 12 of the scraper blade 10 is fully raised, the scraper blade 10 has approximately only half the height, so that the pivot radius of the scraper blade 10 is reduced and at the same time a large swivel angle is made possible.
  • the lower part 12 can be moved downwards, so that the lower part 12 can thread in front of the sliding blocks 24 in the direction of travel.
  • the threading is facilitated by the fact that the vertically extending sliding surfaces 26 are bevelled or rounded at the lower edges 27 to the scraper blade 10 and in that the sliding blocks 24 are rotatably mounted.
  • the sliding surfaces 26 may also be slightly tapered tapering down to also facilitate threading.
  • the rotatable sliding block 24 with a square cross-section allows a flat contact with the sliding surface 26, so that less wear due to the surface contact occurs.
  • the sliding blocks 24 act as locking means when the scraper blade 10 is in the operating position.
  • the actuator 34 engages the upper part 14 of the scraper blade 10 below the pivot axis 18 of the scraper blade 10 on the hinge 36 at. It is understood that two actuators 34 with two joints 36, which form a second pivot axis, may be provided.
  • the pivot axis 18 is therefore arranged vertically higher relative to the hinge 36 and horizontally offset relative to the direction of travel to the rear. In this way, only a small height is required for the pivoting device 30, wherein due to the low point of attack of the actuator 34, the entire pivoting device 30 does not project vertically upwards relative to the upper part 14 of the scraper blade 10.
  • the hinge 36 of the scraper blade 10 is preferably arranged in the plane of the upper part 14 of the scraper blade 10 or at a small distance from this plane.
