Definitions

  • the invention relates to a stripping device for a soil compaction roller with pad feet, with a spar, on which Abstreiferzähne are arranged, and with an optionally adjustable Holmhalterung, which allows readjustment of the Abstreiferzähne to the soil compaction roller.
  • the invention further relates to a soil compaction roller with such a stripping device.
  • the invention has for its object to provide a scraper and a soil compaction roller of the type mentioned, in which a sufficiently large gap to the bandage is present, without increasing the deposit area and the overall length.
  • the spar has a tube, and that the spar holder at least at one end a pair of tube at least partially comprehensive, releasably connected half-shells for non-rotatable and non-sliding jamming of the tube.
  • a basic idea of the invention is therefore that the readjustment of the wiper teeth can be carried out by a pivotal movement of the spar.
  • the rotational movement results in a long feed path, so that the wiper teeth can wear to a large extent without the wiper effect being impaired overall. This can be achieved very long service life.
  • the distance of the spar to the bandage is independent of the travel in the swivel adjustment and can therefore be made as small as possible. Furthermore, the distance of the spar to Traverse independent of the travel can be kept as large as possible.
  • the attachment of the scraper teeth allows a relatively small spar diameter, which has the advantage that the area is relatively small on which soil material can accumulate. Thus, the clogging of the gap between Traverse and bandage is avoided even with sticky material.
  • the spar is a tube with a round, circular or elliptical cross-section. It is also possible to use angular, for example triangular, quadrangular or polygonal cross sections, since these can be held well in a rotationally fixed manner due to the corners. Preferably, however, the spar has a tube with a circular cross section, since this is particularly stable and torsionally stiff.
  • the bearing areas of the scraper teeth have two fingers which engage around the beam in the region of a circle segment, and that the fingers are welded to the pipe.
  • the round cross section facilitates the falling through of soil material and can in Remaining if necessary also be cleaned easily. By embracing fingers, a stable attachment of the wiper teeth is achieved despite the small spar cross-section.
  • a welding distortion of the tube when welding the Abstreiferzähne is avoided by the fact that the fingers are symmetrically angularly offset, preferably diametrically below 180 °, welded to each other on the pipe.
  • a particularly simple to produce and easy to handle attachment of the spar is that at each end of the pipe a pair of half shells for releasable, non-rotatable and non-slip jamming of the tube are present. Standard components can be used for this purpose. With such a clamping device, not only the adjustment of the wiper teeth can be performed by pivoting in a simple manner, but it can also be carried out in the axial direction easy adjustment and tolerance compensation.
  • the delivery is particularly simple in that the half-shells are screwed together, and the screws from the outside, preferably from below, are easily accessible.
  • the half-shells of each pair have at least three on the two half-shells distributed emphasis for generating a three-point clamping.
  • each half-shell of each pair has at least two highlights for generating a four-point clamping.
  • the wiper teeth are preferably forged and provided at their ends with wear caps.
  • Fig. 1 illustrates a bottom compaction roller 11 cut transversely to its axis with stamp feet 12 distributed over the bandage 8.
  • the soil compaction roller 11 is arranged in a frame of two cheeks 6, of which only one is visible in the illustration, and two axially parallel traverses 7, 7 '.
  • stripping devices 13, 13 ' are present between the pad feet 12 in the illustrated example, each extending parallel to the trusses 7, 7' and forming a respective gap 14, 14 'below them.
  • the stripping devices 13, 13 'each have a designed as a tube 2 with a circular cross section spar, which serves as a carrier for solid, forged scraper teeth 1. These protrude radially into the spaces between the pad feet 12, wherein they are in the in Fig. 1 shown state are directed obliquely downwards.
  • each tooth 1 in its support area and base two fingers 18, which surround the tube 2 in the region of a circular segment, for example, about 180 °.
  • the fingers 18 are welded to the pipe 2 at symmetrically diametrically opposed by approximately 180 ° lying welds 10.
  • the tube 2 is releasably held at its two ends in an optionally adjustable Holmhalterung 15, which allows an adjustment of the Abstreiferzähne 1 on the soil compaction roller 11 by pivoting the tube 2 in the direction of arrow 16.
  • the pivot axis lies in the center of gravity of the carrier profile parallel to the axis of the soil compaction roller 11.
  • the Holmhalterept 15 are fixed to the cheeks 6, for example by screwing.
  • the tubes 2 are arranged at a minimum distance from the bandage 8, so that they do not increase the overall length of the frame. In addition, they run with a sufficiently large gap width a parallel to the trusses 7, 7 ', so that the falling through and discharge of stripped soil material, for example according to arrow 17 is reliable.
  • the tube diameter and the foot areas of the scraper teeth 1 have a small diameter and thus form a relatively small area with an effective width b, so that there may possibly be little soil material deposited there.
  • the Holmhalterept 15 each have two half-shells 4, 5, which comprise the tube 2 and are releasably connected by means of screws 3 to form a clamping connection.
  • On the inner surfaces of each half-shell 4, 5 are two, for example, offset by 90 ° emphasis 9 available, so that a good four-point clamping is achieved.
  • the tube 2 When tightened screws 3, the tube 2 is rotatably and non-slip clamped. Thus, the position and orientation of the wiper teeth 1 is fixed. If the screws 3 are released, the tube 2 can be pivoted for radial and axial readjustment of the wiper teeth 1 and moved axially. This delivery is easy because the screws 3 are well accessible from below.
