Definitions

  • the invention relates to an excavator, in particular a backhoe, with a spoon handle and a shovel, which is by means of a Hydraulic motor is pivoted via a linkage.
  • US-A-2,590,454, US-A-4,768,917 and US-A-2,753,059 disclose comparable linkage with triple and double handlebars, however for a front-end loader bucket, which is open to the front and upwards and thus to others Subject to movement conditions.
  • US-A-4,381,167 also shows an excavator with a triple Actuating link and two double guide links, one Form a parallelogram and therefore a compulsory guide for Generate pivoting of the bucket.
  • the problem underlying the invention is seen in that the swivel range of the blade is too small or at Working on a vertical wall too high forces on the Blade tip occur.
  • FIG. 1 shows a construction machine 10 which has a chassis 12 to which wheels 14 are attached to the construction machine 10 to support and move on the floor.
  • the construction machine 10 is equipped with a front loading shovel 16, the one suitable linkage 18 for adjusting the loading shovel 16 compared to the chassis 12.
  • the back area the construction machine 10 is with an excavator of the type Equipped with a backhoe that swivels to the chassis 12 connected boom 20, a dipper stick 22, the one Hinge 24 is pivotally connected to the boom 20, and contains a blade 26 which is in a first bearing 28 the arm 22 pivots.
  • a hydraulic motor 30 to adjust the blade 26 acts on the blade 26 a linkage 32.
  • the construction machine 10 with two Stabilizing struts 34 provided, only one of which is shown is.
  • the construction machine 10 is operated by a Driver's cabin 36 out.
  • the dipper stick 22 shown in FIG. 1 is in length adjustable, which does not affect the scope of protection present invention affects.
  • the hydraulic motor 30 contains a cylinder end 38 which is pivotable at point 40 to the Arm 22 is articulated.
  • the piston end of the hydraulic motor 30 is to a first bearing 46 of an actuating link 44 pivotally attached in the manner of a triple link.
  • the Actuating link 44 has a second bearing 48 provided that a pivot connection to the blade 26th manufactures.
  • the actuating link 44 is also with a third Bearing 50 equipped, which is pivotable on a second Bearing point - also 50 - of a curved guide link 52 attacks.
  • the guide link 52 in turn contains a first one Bearing point 54 for the pivotable connection with the dipper stick 22.
  • An essential feature of the present invention is that geometric arrangement of the bearings 46, 48, 50 of the Actuating link 44.
  • the third Bearing 50 of the control arm 44 between the first and second bearing 46 and 48 are provided.
  • the first and second bearings 46 and 48 of the Actuating link 44 a level above, i. H. of the Dipper stick 22 facing away, the third bearing 50 located.
  • the second and the third Bearing 48 and 50 one level.
  • the first bearing 46 lies below this level and is located on the dipper stick 22.
  • a second, the first level in the third bearing 50 intersecting plane can be formed perpendicular to the first. Proceeding from this, the first bearing 46 lies above it Plane and the shovel 26 out of the way.
  • the present arrangement of the bearings, the Actuating link 44 and the guide link 52 ensures a compared to the flatter that can be achieved with conventional poles Edge cutting force curve of the blade 26, since the blade 26 from an extreme return position to an extreme one Position moved.
