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 reveal comparable booms with triple and double Handlebars, but for a front-connected one Loader bucket that is open to the front and top and thus other movement conditions.
  • US-A-4,381,167 also shows an excavator with a triple control arms and two double Guide links that form a parallelogram and therefore one Generate positive guidance when swiveling 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.
  • the control link and the control link can be the same Length of the hydraulic motor, which in the simplest case Double-acting hydraulic cylinder is a longer travel range the bucket can be reached, which is an advantage because im Transport operation the bucket closer to the dipper stick and pivoted further back when working on vertical walls can be.
  • 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.
  • Construction machine 10 is equipped with a front loading shovel 16 which a 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 Backhoe equipped, one swivels to the chassis 12 connected boom 20, a dipper stick 22, the over a joint 24 is pivotally connected to the boom 20, and includes a bucket 26 located in a first bearing 28 pivots on the dipper stick 22.
  • On Hydraulic motor 30 is applied to adjust the blade 26 the blade 26 via a linkage 32.
  • the Construction machine 10 provided with two stabilizing struts 34 from which only one is shown. Operating the construction machine 10 takes place from a driver's cab 36.
  • 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 at a first bearing 46 one Actuating link 44 in the manner of a triple member pivotally attached.
  • the actuating link 44 is with a provided second bearing 48, which is a pivot connection the blade 26 produces.
  • the control arm 44 is also equipped with a third bearing 50 which is pivotable at a second bearing - also 50 - a curved one Control arm 52 attacks.
  • the guide link 52 contains again a first 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 deposit 46 lies below this level and is the dipper stick 22 added.
  • a second, the first level in the third Bearing point 50 intersecting plane can be perpendicular to the first be formed.
  • the first depository is based on this 46 above this level and the blade 26 remote.
  • 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 as the blade 26 from an extreme return position to an extreme applied position moved.
