Definitions

  • the invention relates to an excavator, in particular a backhoe, with a dipper stick and a shovel, which is pivoted by means of a hydraulic motor via a linkage.
  • US-A-2,590,454, US-A-4,768,917 and US-A-2,753,059 disclose comparable linkages with triple and double handlebars, but for a front-mounted loader bucket that is open to the front and up and is therefore subject to different movement conditions.
  • the US-A-4,381,167 also shows an excavator with a triple actuating link and two double guide links, which form a parallelogram and therefore generate a positive guidance when pivoting the bucket.
  • FIG. 1 shows a construction machine 10 which has a chassis 12 to which wheels 14 are attached in order to support and move the construction machine 10 on the floor.
  • the construction machine 10 is equipped with a front loading shovel 16 which has a suitable linkage 18 for adjusting the loading shovel 16 relative to the chassis 12.
  • the rear area of the construction machine 10 is equipped with an excavator in the manner of a rear excavator, which contains a boom 20 pivotally connected to the chassis 12, a dipper stick 22 which is pivotally connected to the boom 20 via a joint 24, and a bucket 26 which pivotally engages on the dipper arm 22 in a first bearing point 28.
  • a hydraulic motor 30 for adjusting the blade 26 acts on the blade 26 via a linkage 32.
  • the construction machine 10 is provided with two stabilizing struts 34, only one of which is shown is.
  • the construction machine 10 is operated from a driver's cab 36.
  • the dipper stick 22 shown in FIG. 1 is adjustable in length, which does not affect the scope of the present invention.
  • the hydraulic motor 30 includes a cylinder end 38 which is pivotally connected to the dipper arm 22 at the point 40.
  • the piston end of the hydraulic motor 30 is pivotably attached to a first bearing 46 of an actuating link 44 in the manner of a triple member.
  • the actuating link 44 is provided with a second bearing point 48, which establishes a pivot connection to the blade 26.
  • the actuating link 44 is also equipped with a third bearing point 50 which pivots on a second bearing point - likewise 50 - of a curved guide link 52.
  • the guide link 52 in turn contains a first bearing point 54 for the pivotable connection to the dipper arm 22.
  • An essential feature of the present invention is the geometrical arrangement of the bearing points 46, 48, 50 of the actuating link 44.
  • the third bearing point 50 of the actuating link 44 is provided between the first and second bearing points 46 and 48 thereof.
  • the first and second bearings 46 and 48 of the actuating link 44 define a level above that, i.e. H. facing away from the dipper arm 22, the third bearing 50 is located.
  • the second and third bearings 48 and 50 define a plane.
  • the first bearing 46 lies below this level and is located on the dipper stick 22.
  • a second plane intersecting the first plane in the third bearing 50 can be formed perpendicular to the first. Proceeding from this, the first bearing 46 lies above this level and the blade 26 is remote.
  • the present arrangement of the bearing points, the actuating link 44 and the guide link 52 provides a flatter edge cutting force curve of the blade 26 that can be achieved with conventional linkages, since the blade 26 moves from an extreme return position to an extreme applied position.
