Definitions

  • the present invention relates to a toolholder arrangement, especially side dump bucket arrangements for vehicle mounted loaders.
  • an excavator bucket or shovel of open end design and with a gradually increasing bottom height towards the ends is known.
  • An excavator bucket of this type offers little resistance during the digging operation and has a convenient capacity in relation to the width of the vehicle.
  • the excavated material in addition to conventional front dumping can also be discharged in a time saving and advantageous manner by side dumping in one or the other lateraldirection.
  • the three-way dumping bucket of the kind mentioned has because of its advantages been followed by several predecessors which, however, do not exhibit the same qualities.
  • FIGS. 1, 2 and 4-7 show rear elevational views of different digging structures having side dump bucket arrangements, wherein:
  • FIG. 1 illustrates a first embodiment in the digging position.
  • FIG. 2 shows the embodiment according to FIG. 1 in a position immediately after an impulse for side dumping to the right.
  • FIG. 3 shows the embodiment ac cording to FIG. 1 in a position of full side dumping to the right, whereas FIG. 4 shows the same embodiment in a position of side dumping to the opposite side.
  • FIG. 5 is a View of the central portion of a modified cylinderholding structure in the digging position, whereas FIGS. 6 and 7 illustrate said embodiment more in detail in different positions upon an impulse for side dumping to the left.
  • the right portion of FIG. 7 shows a modification having auxiliary locking members.
  • FIG. 8 is a partly broken top view of the drive cylinder.
  • FIGS. 9 and 10 are side elevational views of a modified embodiment having auxiliary locking members in a position ready for side dumping and a side dumping position, respectively.
  • the forward and two-way side dumping arrangement comprises a bucket 1 and a cradle 2 supported on laterally spaced lift arms 3 at pivot stub shafts 3'. Laterally spaced tilt arms 4 are also employed and are pivotably attachable to the cradle by means of pivot stub shafts 4'. Forward dumping of the bucket can, thus, take place.
  • a bucket or shovel is attached to the cradle by special locking means at each end portion of the cradle 2.
  • Said locking means comprises a bar 6 extending between the end portions of the cradle.
  • the cradle has on each side two parallel lugs 7, 8 which receive pivot pins 9', 10 secured to flange portions 1a, 1b of the bucket.
  • the bar 6 is displaceable between a central position shown in FIG. 1 in which both pivot pins 9, 10 are secured to the cradle by means of end portions 6a, 6b of the bar and the positions shown in 'FIGS.
  • a hydraulic jack comprising a cylinder 15, a piston 15a, and two piston rods 16, 17, the head portions 161:, 17a of which are engageable to and disengageable from the bucket, is used for pivoting the bucket in either direction.
  • the cylinder 15 is carried by a pair of brackets 18 on the cradle by means of projecting centered hubs 19 engaging V-shaped guide slots 20 in the brackets 18.
  • the cylinder 15 has two connections 21 and 22 to the hydraulic control system of the vehicle.
  • conduits 25 and 26 are conduits of the so-called third valve circuit which is common on most tractor vehicles.
  • this third valve control circuit has to be used for locking the bucket to the cradle in the central digging and frontdumping position, selectively releasing pivot pins 9 or 10, efiecting side dumping and returning operations in both directions as well as after returning the bucket locking it to the cradle.
  • piston rod heads 16a, 1711 are received in downwardly directed recesses 1e, If in bucket brackets 1a, 1b.
  • conduit 26 A continued impulse in conduit 26 will eifect left hand side dumping of the bucket to the position shown in FIG. 4.
  • Bracket 18 carrying and guiding cylinder 15 can be constructed in a number of ways.
  • hub 19 is guided by a straight recess 20'.
  • Cams 30, 31 guide one piston rod head during the side dumping operation after having permitted disengagement between the other piston rod head and the bucket bracket 1a or 1b.
  • the locking means of the cradle during digging may be as shown to the right in FIG. 7 and in FIGS. 9 and 1 0. It may consist of two parallel tubes 2a, 2b located on difierent levels, each of said tubes cooperating with a corresponding U-shaped supporting and locking member 10, 1d below the bucket inside flanges 1a, 1b respectively. In this case locking is effected due to the fact that the supporting points between the bucket and the cradle take moments about axes at right angles to the digging direction. When the bucket is not subjected to digging forces, it can be freely tilted in the way described above.
  • link 28 connected to cylinder 15 by means of hub 19 has a bent-over portion 28a which is attached to bar 6. Bar 6 is displaceable within the tube 2:: and has at its ends downwardly directed portions, the one denoted 6 shown in FIG. 9. To said portion 6f is attached the detent member 6b engaging and releasing, respectively, pivot 10.
  • a side dumping bucket arrangement for use on a tractor comprising a cradle carried by a tractor, a bucket mounted on said cradle on at least two laterally spaced supports, releasable locking means at two of said spaced supports, an hydraulic jack means for exerting a dumping force on said bucket at either of two laterally spaced points thereon, a lost motion device connecting said hydraulic jack means and said releasable locking means, whereby said hydraulic jack means, when moved in one direction, releases one of said locking means and subsequently pivots said bucket about the other locking means as a pivot and hydraulic means operable to actuate said hydraulic jack means and said lost motion device to dump said bucket on one side.
  • a forward and two-way side dumping arrangement comprising a cradle having first and second end portions, a bucket on said cradle, lift means for raising and lowering said cradle, tilt means for tilting said cradle relative to said lift means for forward dumping, said cradle being pivotally interconnected to said lift means, first and second locking means attaching said bucket to said first and second end portions of said cradle, respectively, when the bucket is maintained thereon in its normal horizontally disposed position, means for releasing one of said locking means and for retaining the other locking means in attached relationship between the bucket and the cradle, drive means for pivoting said bucket about the retained locking means, means operatively connecting said drive means to said locking means to selectively release one of said locking means prior to pivoting the bucket about the retained locking means, said drive means comprising a hydraulic jack having a cylinder and two piston rods therein engaging different portions of said bucket, link means operatively connecting said cylinder to said locking means, said cylinder being substantially horizontally mounted on said
