Definitions
- the invention is directed to an excavator in the preamble of claim 1 specified genus, as is WO-A-89/12145.
- the present invention is directed to further training an excavator bucket, especially a bucket. It there are cases where there is an operator of such an excavator would be useful e.g. with a To be able to grasp the shovel, for example to handle large fragments to be able to transport, building pieces, larger timber or Reinforced concrete beams u. the like
- a spoon known with two pivotally arranged thereon, over separate hydraulic drives movable gripper elements.
- the bucket is in the usual way on the Excavator boom attached.
- DE-A-30 04 834 also shows an excavator bucket attached to the excavator boom or arm arranged pivotably in a conventional manner is, with a counter-gripping element on the auxiliary hydraulic cylinder is articulated such that when the spoon is pivoted in the closed position, the counter element also in the closed position is effected, the opening movement takes place in reverse.
- WO 89/12145 again shows one bucket linked to the excavator boom via two support disks, the support disks having hydraulic cylinders, with which gripping tines can be moved.
- the object of the invention is to provide a solution with which increases the mobility of the spoon and at the same time the individual closing and opening of a gripping tool is made possible.
- a practical design of the excavator bucket exists thereby in that the gripping plate with two pairs of each Backplate is provided, the at the top Swivel fitting and the fastening fitting at the lower end for the piston / cylinder unit and take one Form part of the carrier swivel arm.
- Another possible embodiment of the invention exists in making the gripping plate itself like a spoon.
- the invention also provides that the tool with a Rotating and / or swiveling device is provided for rotation or swiveling the bucket with gripping plate in one from the swivel plane of the bucket or the gripping plate deviating level.
- the excavator generally designated 1, on its special Design does not matter here, has a working or basic boom 2 on which a dipper stick 3 pivotable via a hydraulic piston / cylinder unit 4 is stored.
- the dipper stick is pivoted at its free end a carrier swivel frame 5, the other swivel 6th via a coupling piece 7 and a rocker 8 with a Spoon cylinder 9 is operatively connected.
- a swivel 10 Blade 11 On the support and swivel frame is a swivel 10 Blade 11 arranged beyond the pivot joint 10 pointing a swing arm 12, at the free End 13 another hydraulic piston / cylinder unit, called gripper cylinder 14 for short, attacks.
- the gripper cylinder 14 is pivoted at the lower end 15 articulated by back plate 16, the back plate Represent 16 elements of the support and swivel frame 5.
- Gripper plate 17 which in turn in the example shown is spoon-like at least in some areas.
- the blade is relative to the gripper plate 17 brought into the open position, e.g. in the position of Fig. 1.
- the dipperstick is hydraulic Piston / cylinder unit pivoted, for example the basic boom 2 in the assumed position can stay.
- the gripper cylinder 14 is actuated, such that the scoop 11 is on the gripper plate 17th too moved.
- the closed position can also be supported or corrected with a spoon cylinder 9.
- the hydraulic circuit and control of the various Working methods and work movements can be designed that all work movements are carried out separately or but also in such a way that movements are superimposed.
- the advantage is that the independent movements with the typical gripper working movement at a shorter distance from the pivot point on the swivel arm to the blade edge are present, resulting in higher crushing and lifting capacities leads.
- Fig. 5 the spoon movement is shown, whereby by means Double arrows 19 to 21 the respective pivoting options are shown.
- Double arrow 21 is torn out shown in which swivel range a spoon can move according to the prior art. Is recognizable both the opening area and the closing area of the Blade 11 with the device according to the invention clearly larger, as shown by the double arrows 19 and 20.
- the excavator handling tool is simplified in perspective shown with supervision of the carrier swivel frame 5 with the piston / cylinder units arranged there 14 and the one holding it at the articulation point 15 Back plate 16, which is part of the swing frame 5th form. 6 also shows how the spoon or the bucket 11 with its swivel arms 12 on the swivel joint 10 of the back plate 16 is arranged.
- both the gripper plate 17 and the shovel 11 be provided with recesses pointing inwards, in order, for example, to do this when using the corresponding device frequently occurs, round elements, such as pipes or beams, easier to grip.
- the arrangement of the hydraulic Piston / cylinder units 14 otherwise of the same construction are reversed, i.e. these can on be arranged on the back of the blade, the then Swivel boom 12 are attached to the swivel frame 5.
