Definitions

  • the present invention relates to an arrangement in a drivable excavator comprising a wheel or caterpillar supported under ⁇ body with a cab and a digging arm comprising a digging beam which is linked to said underbody, a digging arm which is linked to the free end of said beam and has a digging bucket provided on its outer end, and wherein the movements of said arm and bucket are caused by hydraulic working cylinders.
  • this is achieved in a drivable excavator of the kind mentioned above with the characteriz ⁇ ing features of the invention being that the points of attachment of the working cylinder for the digging beam are provided to permit said beam to be turned from a digging position across its upper dead centre to a lowered horizontal folded up position, and that the beam foot is, in a manner known per se, pivoted laterally of the cab.
  • a preferred embodiment of the invention is characterized by the fact that said beam is angular with the apex of said angle facing backwards, i.e. away from the digging bucket, and that the beam foot is pivoted in a bracket projecting upwards from said underbody with the turning axis at a distance above said underbody which is equal to or slightly larger than the arm of the angle that is located closest to said turning point.
  • Figure 1 shows an excavator turned 360 in the digging posi ⁇ tion
  • Figure 2 shows the machine in a first step of folding up the digging aggregate into a transport position
  • Figure 3 shows a second step of folding up said digging aggregate
  • Figure 4 shows said digging arm means completely folded up on the underbody
  • Figure 5 shows the machine with a folded up digging aggregate according to Figure 4 in a plan view
  • Figure 6 is a view in perspective of said excavator with supporting feet which are used as lifting arms for a three- point mounted tool, " and
  • Figures 7 and 8 show alternative embodiments of the location of the working cylinder moving the digging beam.
  • the excavator of the shown embodiment is a machine running on wheels and providing a rotation of 360 , with a cab 1, and machine housing 2 being mounted for 360 rotation on a drivable chassis 3 with wheels 4 and 5.
  • Machine housing 2 is provided on an underbody in the shape of a circular plate 7, on which a bracket 8 is mounted to carry digging aggregate 9.
  • the lat ⁇ ter comprises an angular digging beam 10 having a short leg 11 which at its free end is pivoted in upper end of bracket 8 about axis 12.
  • Beam 10 can be turned in a vertical plane by the aid of a cylinder 13, which is attached to bracket 8 at a point 14 located below and in front of axis 12. The other end of the cylinder attacks at a point 15 on beam 10.
  • a digging arm 16 is pivoted in the outer free end of beam 10 and is movable by the aid of a hydraulic cylinder 17, via linked arms 18.
  • a turnable digging bucket 19 is provided, and is movable by the aid of a hydraulic cylinder 20, via linked arms 21.
  • the digging aggregate will then be positioned horizontally on the udnerbody of the machine, at the side of the cab and machine housing. In this position the digging aggregate will not project outside the underbody of the machine in a rear ⁇ ward direction and the centre of gravity of the entire machine will have a low position, providing a favourable position of transport for the machine to be driven on a road.
  • this machine may also be pro ⁇ vided with a telescopic front loader which is mounted on chassis 3. Additionally, a three-point suspension with top stays 22 and pull stay members 23. is provided, and a tool 24, in the shown embodiment a rotary cultivator, is mounted on said three-point suspension. Supporting feet which may be used during digging operations or when said front loader is utilized, may be mounted to said pull stay members 23.
  • FIG. 7 an alternative manner of attaching cylinder 13 is shown.
  • Beam 10 is secured to a bracket 8 ,as in the above em ⁇ bodiment.
  • Cylinder 13 is secured to beam 10 at the apex of its angle, and the other end 14 is attached to said circular plate 7 behind said digging aggregate in its digging position.
  • FIG 8 another arrangement for turning said beam 10 is shown.
  • This arrangement comprises a working cylinder 13' which with one of its ends is secured to plate 7 at the front end of bracket 8.
  • the other end of working cylinder 13' is attached to the free end of a rocking lever 25 , one end of which is pivoted to upper end of bracket 8.
  • a second working cylinder 13" has also one end attached to the free end of rocking lever 25, and its other end is attached to the under ⁇ side of beam 10.
  • This arrangement is somewhat more complicat ⁇ ed, but it permits turning said beam across its dead centre without any need of manipulating digging arm and bucket.
  • the essential advantages of the invention are, as mentioned above, a low position of the center of gravity when the ma ⁇ chine is driven, as well as compact exterior dimensions when the digging aggregate is lowered,and that said digging aggre ⁇ gate does not impair visibility in this position during driving operations or when other tools are used.
  • Said digging beam may, e.g. be a straight member, even though the angular shape has great advantages.

Abstract

Conception de pelle mécanique, en particulier une pelle orientable sur 360o, constituée d'un châssis (3) supporté par des roues ou chenilles, d'une cabine (1) ainsi que d'un ensemble de creusement (9) comprenant une poutre de creusement rigide (10), pivotant sur une partie inférieure (6), un moyen à bras de creusement (16) orientable et connecté à l'extrémité libre de ladite poutre (10), à l'extrémité extérieure duquel se trouve un godet (19) de creusement, les mouvements de la poutre (10), du moyen à bras (16) et du godet (19) étant assurés par des cylindres de travail hydrauliques. Les points de fixation (14, 15) des cylindres de travail (13) de la poutre (10) sont disposés de manière à permettre la rotation de la poutre (10) depuis une position de creusement, en passant par le point mort haut, jusqu'à une position pliée horizontale inférieure sur la partie inférieure (6). Le pied de la poutre pivote sur une console (8) faisant saillie depuis la partie inférieure (6) vers le haut, l'axe de rotation (12) étant situé à une distance au-dessus de la partie inférieure (6) qui est ßgale ou légèrement supérieure à la longueur du pied (11) de l'angle de poutre situé le plus près dudit point de rotation (12).
