Definitions

  • the present invention relates to a separator bucket device comprising a grid for separation of excavated material, especially road material containing gravel, of the kind described in the introduction of claim 1.
  • Separator buckets of the above-mentioned kind are known (Tojo Maskin, Klarila, Sweden) and are usually mounted on wheeled loaders which after cutting of road borders by means of, for example, an excavator take care of the road material cut away in order to return gravel to the road and to remove material unsuitable to be used as road surfacing.
  • a disadvantage of the known separator buckets is that parts of these have a limited life and must be exchanged rather often, which is time-consuming and uneconomical. This particularly applies to the rubber bushings and the bearings connecting the eccentrics of the drive shaft with the grid portions forming a grid.
  • the separator bucket shown in Figure 1 and indicated by 1 comprises a rear part 2, two side walls 3, a cutting plate 4 and a frame 5 extending between the side walls 3. Said parts are welded to each other.
  • the bucket 1 has no real base but is provided with a grid in the form of two grid portions 6 and 7 partly inserted in each other.
  • Each grid portion comprises a number of parallel rods 6a and 7a respectively, one end of each rod being rotatably connected with a shaft mounted between the side walls 3 adjacent to the cutting plate 4.
  • the other end of each rod 6a is connected with a front plate 9, and the other end of each rod 7a is connected with a rear plate 10 which is parallel to the front plate 9 and located partly under the same.
  • the plates 9 and 10 are vertically movable and receive such reciprocal movement in the way described below.
  • the frame 5 there are mounted four bearing brackets 11, in which a drive shaft 12 is rotatably mounted.
  • the drive shaft 12 is driven by a hydraulic motor 13 mounted on the frame 5.
  • the drive shaft 12 is provided with four eccentric discs 14 ( Figures 3 and 4) surrounded by bearing housings 15 and 16. Through their parts located furthest away from the drive shaft 12, the eccentric discs 14 located in the bearing housings 15 are displaced 180° relative to the corresponding parts of two other eccentric discs located in the bearing housings 16.
  • the bearing housings 15 are connected with the front plate 9, and the bearing housings 16 are connected with the rear plate 10 in the way described below and shown especially in Figure 4.
  • the bearing housings 15 and 16 are provided with projections 15a and 16a respectively, each of which has a cone-shaped body 17 mounted thereto.
  • a flexible member in the form of a spring steel member 18 with welded reinforcement plate 23 is provided with a hole 18a.
  • a conical sleeve 19 fits to the body 17 and into the hole 18a.
  • the arms 18 are connected with the plates 9 and 10 in the same way as the ends of the arms 18 facing towards the shaft 12 are connected with the projections 15a, 16a, as shown in Figure 4 wherefore an explanation will not be required.
  • the details of the lower attachment device shown in Figure 4 are provided with the same reference numbers, though primed, as the corresponding details of the upper attachment device.
  • attachment devices 17-22 and 17'-22' there is provided a play-free, easily dismountable and mountable as well as reliable connection between the bearing housings 15, 16 and the grid portions 6 and 7 of the grid with the rods 6a and 7a.
  • the motor 13 is started, the plates 9 and 10 being moved vertically towards and from each other because of the two bearing housings 15 acted on by the eccentric discs 14 displacing the associated arms 18 upwardly while the two other bearing housings 16 acted on by the eccentric discs 14 displace the associated arms downwardly, and vice versa.
  • the two grid portions will receive contrary rotary movements about the shaft 8 such that large pieces of, for example, soil, will be disintegrated, and gravel and other small particles will enter the spaces between the rods and fall through these on to the road, whereas large pieces of, for example, turf will stay on the grid.

Abstract

Un système de triage pour pelle mécanique avec une grille pour trier les matériaux excavés, la grille comprenant au moins deux parties de grille véritablement parallèles (6, 7) insérées l'une dans l'autre, une des extrémités de chaque partie de grille étant montée de manière rotationnelle sur la pelle mécanique (voir 8) et l'extrémité opposée de chaque partie de grille étant reliée, par un système de transmission du mouvement (15-22), à au moins un arbre de transmission (12) doté d'excentriques (14), de telle sorte que par la rotation de l'arbre de transmission, les parties de grille subissent un mouvement de rotation de l'une vers l'autre dans le bâti de la pelle mécanique. Le système de transmission du mouvement se compose de membres flexibles et allongés (18), dont les extrémités sont reliées fixement aux parties de grille (6, 7) ainsi qu'aux éléments (15, 16) du système de transmission du mouvement monté sur les excentriques.

Claims (4)

  1. Dispositif de godet séparateur comprenant une grille servant à séparer la matière enlevée, la grille comprenant au moins deux parties de grille (6, 7) sensiblement parallèles, imbriquées l'une dans l'autre, une extrémité de chaque partie de grille étant montée rotative dans le godet (en 8) et l'extrémité opposée de chaque partie de grille étant reliée, à l'aide d'un dispositif de transmission de mouvement (15 à 22), à au moins un arbre d'entraînement (12) muni d'excentriques (14), de telle manière que, sous l'effet de la rotation de l'arbre d'entraînement, les parties de la grille reçoivent un mouvement de rotation qui les rapproche et les éloigne l'une de l'autre par rotation autour de leur montage dans le godet, caractérisé en ce que le dispositif de transmission de mouvement (15 à 22) comprend des éléments flexibles allongés (18), dont les extrémités sont reliées rigidement aux parties (6, 7) de la grille, ainsi qu'à des parties (15, 16) du dispositif de transmission du mouvement qui sont montées sur les excentriques.
  2. Dispositif selon la revendication 1, caractérisé en ce que les éléments flexibles (18) sont des éléments en acier à ressorts ou analogues qui sont flexibles dans un plan.
  3. Dispositif selon la revendication 1 ou 2, caractérisé en ce que la liaison fixe entre une extrémité, ou l'autre extrémité, d'un élément flexible (18) et une partie de grille (6, 7) ou une partie (15, 16) d'un dispositif de transmission de mouvement (15 à 22) montée sur un excentrique (14) comprend des éléments de liaison de forme conique (17, 19).
  4. Dispositif selon la revendication 3, caractérisé en ce qu'un corps (17) de forme conique est relié à la partie de grille (6, 7) et/ou à la partie (15, 16) du dispositif de transmission de mouvement montée sur l'excentrique (14), en ce qu'un manchon (19) de forme conique est monté sur ledit corps et est inséré et s'ajuste dans un trou (18a, 18a') de l'élément flexible (18) et en ce qu'une vis (20) est passée à travers le manchon et vissée dans le corps, et exerce une pression sur le manchon.
