  • the device functions to maintain the blade in scraping engagement with the drum surface [56] References Cited even though the drum oscillates or vibrates about its UNITED STATES PATENTS 1,156,248 10/1915 Nichol 280/158 R 6 Claims, 4 Drawing Figures PMENTEDAPR 9 am SHEET 2 OF 2 j 1 APPARATUS FOR SCRAPING COMPACTING DRUMS BACKGROUND OF THE INVENTION
  • the present invention relates generally to apparatus where the drum rotates about'a fixed axis, this presents no serious problem. However, the same is not true of vibratory rollers, where the roller drum when vibrating is constantly in oscillatory motion relative to the frame.
  • apparatus for continuously cleaning the surface of a rotary compaction drum, and especially vibratory roller drums includes one or more linkage arms pivoted at oneend to the roller frame and provided adjacent the other end with-a scraper blade, or blades, that is adapted to engage and clean the drum'surface.
  • Oneor a plurality of rollers carried by the linkage arms ride on .the drum, and are dimensioned relative to the scraper bladeor blades such that both the rollers and the blades simultaneously bear against the drum surface. Effective scraping contact of the blades with the drum is maintained,
  • FIG. 1 is a side elevational view of one embodiment of roller drum scraping apparatus constructed in accordancewith the invention, with parts broken away for clarity of illustration;
  • FIG. 2 is a front elevational view taken along the line 2,-2 of FIG. 1 and looking in the direction of the arrows;
  • FIG. 3 is a side elevational view of another embodiment of the invention, also showing certain parts broken away for clarity;
  • FIG. 4 is a partial vertical sectional view taken along the line 44 of FIG. 3 and looking in the direction of the arrows.
  • a linkage arm 14 is piv- I oted at one end to a suitable element 16 of the frame 12 so as to be movable about the pivot pin 18 towards and away from the rotational axis, indicated generally age arm.
  • Two blades are secured to the 'U-shaped memher, one to each leg, which hasits open side facing the drum.
  • the rollers are located interiorly of the U-shaped member and are paired circumferentially of the drum to maintain the blades in proper scraping relation to the drum surface.
  • the blades may be flexible or slidably bolted to the supporting mence.
  • a preferred construction of the linkage arm 14 includes two L-shaped members 22 (see FIG. 2) that are attached at their free ends to the rear flange 24 of an axially extending member 26 which projects toward the drum. Both L-shaped members. 22 pivot about the pin 18.
  • Bolted or otherwise fastened to the member 26 is a scraper blade 28 that is adapted to engage the compaction surface 30 of the drum.
  • the inner end of the blade 28 may be appropriately chamfered (see FIG. 1 )to enhance the scraping action of the blade.
  • Linkage arm 14 is further provided with a roller 32 at a point'intermediate of its ends. As depicted in FIG. 2, the roller is journaled between the parallel legs of the L-shaped members 22, and is positioned thereon so that it can make rolling contact with the drum surface 30. It is a feature of the invention that the scraper blade 28 and roller 32 are dimensioned and mounted on the arm 14 to bear against the surface 30 simultaneously. They are resiliently maintained in this position by a tension spring 34 connected between the member 26 and the frame 12 Thus the blade 28 and roller 32 follow the drum 10 in its oscillatory motion within the frame 12, with the blade always being held in scraping position against the surface 30.
  • a second linkage arm of identical construction as the arm 14 is positioned adjacent the other end of the drum. That arm is also equipped with a roller and tension spring.
  • the link arms 14 optimally are positioned on the frame 12 so that the blade 28 is located below the horizontal centerline of the drum, i.e., below the axis 20.
  • the blade 28 may of course be located at other areas of the drum if considerations of space or the like so require.
  • another complete similarly mounted scraping unit, including the arms 14, blade 28, rollers 32 and springs 34, is preferably provided on the other side of the line of contact of the drum with the material to be compacted to ensure that the drum surface 30 is properly cleaned in both directions of travel.
  • the blade may be adjustably mounted on the member 26.
  • a plurality of bolts 36 and a backing strip 38 may be conveniently employed, with the blade 28 being formed with elongate slots 40 for receiving the bolts in an adjustable manner.
  • FIGS. 3 and 4 An alternative embodiment of the invention is portrayed in FIGS. 3 and 4, where like reference numerals indicate like parts. Again, only one end of the drum and scraper apparatus is illustrated, but it will be understood that substantially identical structure, save for any necessary reversal of parts, is also provided at the other end.
  • link arms 14a are located at opposite ends of the drum 10, and are pivoted thereat, as by a clevis 44 and pin 46, to a suitable element of the roller frame 12.
  • the arms are resiliently coupled to the frame l2at their free ends by tension springs 34.
  • the points of connection of the U-shaped member 50 to the arms 14a preferably lie in the vertical plane passing through the rotational axis of the roller, the U- shaped member being symmetrical in cross section about those points (see FIG. 3).
  • Paired rollers 32 mounted interiorly of the U-shaped member 50 on cross members 54 (see FIG. 4) and spaced one on either side of the plane of symmetry of the member, ride on the surface 30 and maintain the U-shaped member centered about the pivot pins 48.
  • Several sets of the paired rollers 32 may be positioned along the drum, as indicated in FIG. 4.
  • each leg of the U-shaped member 50 Attached to each leg of the U-shaped member 50 is an axially extending scraper blade 28 which, as before, may be adjustable relative to the member 50 by means of bolts 36 and slots 40.'The blades 28 are so positioned that both they and the rollers 32 simultaneously bear against the surface under the action of the springs 34. Effective scraping of the surface 30 is afforded in both rotational directions by this two-blade construction.
  • the scraping apparatus of FIGS. 3 and 4 preferably is arranged to straddle the axis of rotation 20 of the drum at the highest point on the drum circumference, but other circumferential locations may be adopted as well.
  • the blades 28 may be constituted by flexibIe members so that they will deflect slightly when brought into contact with the drum surface. This not 6 It will be understood by. those skilled in the art that the above-described embodiments are intended to be merely exemplary, in that they are susceptible of modification and variation without departing from the inventive concepts disclosedf All such variations and modifications, therefore, are intended to be included within the spirit and scope of the invention as defined in the appended claims.
  • Apparatus for scraping the surface of a rotary compaction drum .mounted on a frame comprising:
  • At least one scraper blade supported by the linkage arms for movement therewith towards and away from the drum axis and adapted to scrape the drum surface, said blade being an axially extending blade attached to the free ends of the linkage arms;
  • each linkage arm in association with the scraper blade at a point intermediate to the pivotally attached end and the free end for movement therewith towards and away from the drum axis and adapted to make rolling contact with the drum surface, the associated scraper blade and rollers being dimensioned to place the scraper blade in scraping engagement 1 with the drum surface when the rollers engage the drum surface; and means for urging the scraper blade into scraping engagement with the drum surface and the associated rollers into rolling contact with the drum surface.
  • Apparatus for scraping the surface of a rotary compaction drum mounted on a frame comprising:
  • a plurality of rollers mounted on the interior of the U-shaped member and adapted to make rolling contact with the drum surface, the scraper blades and rollers being dimensioned to place the scraper blades in scraping engagement with the drum surface when the rollers engage the drum surface;
  • Apparatus according to claim 3 further comprising spring means for. resiliently urging the scraper blades and rollers toward the drum surface.
  • Apparatus according to claim 3 further comprising in rolling contact with the drum surface. slidable means for attaching the blades to the legs of 6.
