Definitions
- the invention relates to a backhoe according to the preamble of claim 1.
- a backhoe is from
- Additional backhoe buckets must also be transported and stored. They must also be handled with considerable care to prevent contamination of the receptacle and the hydraulic lines. Additional backhoe buckets are also only available in certain widths, so that there is often the need to choose a particular backhoe bucket that is not optimal in its width. These are considerable disadvantages of the
- the invention is therefore based on the object of creating a continuously adjustable backhoe bucket in which the force of the positive guidance of the bucket parts against one another only decreases to a small extent and the parallel guidance of the
- Labeling part of claim 1 is designed.
- Fig. 1 is a schematic side view of the bucket
- 2A is a view of the bucket from the direction of
- FIG. 2B like Figure 2A, but in the extended
- Fig. 3 is a view of the bucket along the cutting line
- Fig. 4 is a view of the bucket from the direction of
- 5A is a view of the bucket from the direction of
- 6A is a view of the bucket from the direction of
- Scissors. 7 shows a schematic section through the backhoe bucket as in FIG. 3 with a second scissor system
- Boom head of a backhoe is in its width is infinitely variable between a minimum value b1 (FIG. 2A) and a maximum value b2 (FIG. 2B).
- the backhoe 1 consists of a fixed central
- Middle shell 2 and two side shells 31, 32 which can be extended to the middle shell 2 and are mirror-symmetrical to one another.
- the extension movement of the rare shells 31, 32 is positively guided on the middle shell 2, the positive guidance preferably consisting of at least two double scissors 5, 6.
- FIGS. 5A, 5B show the double scissor system 5 in the retracted state (FIG. 5A) and in the extended state
- the double vision system 5 consists of a double scissors 51 and a preferably hydraulic pressure piston 52 for retracting and extending the double scissors 51.
- the double scissors 51 the outer pair of joints 511, 512 on the side shell 31, the outer pair of joints 513, 514 on the rare shell 32 and the middle pair of joints 515, 516 positively guided on the middle shell 2.
- the forced guidance takes place in such a way that the joints 511, 513, 515 are mounted in a stationary and pivotable manner, while the joints 512, 514, 516 are each pivotably mounted on a sliding body 53, which in turn is displaceable in a rail 54. Due to this forced guidance, there is an absolutely parallel one
- the double scissor system 5 consists of two
- Double scissors act alternately on the side shells 31, 32. Alternately means that the first and third arms engage side shell 31 and the second and fourth arms engage side shell 32.
- both double shear systems 5, 6 each have two
- the pressure piston 52 is double-acting, i.e. he practices his
- Double scissors 51 possible. These can be: pneumatic pressure pistons and electrical drive through a rotating spindle.
- FIGS. 6A, 6B show the double scissor system 6 in the retracted state (FIG. 6A) and in the extended state
- the structure of the double vision system 6 corresponds to that of the double scissor system 5.
- This scissor system also consists of double scissors 61 and a preferably hydraulic pressure piston 62.
- the two pressure pistons 52, 62 are in the
- the side shell 31 includes the middle shell 2 on the inside with the shell part 311 and on the outside partly with the shell parts 312, 313. The same applies to the side shell 32.
- the middle shell 2 is with a Stiffening rib 21 stiffened by two
- Triangular gusset plates 22, 23 are connected to the receptacle 4. In each triangular gusset 22, 23 there is a mounting opening 221, 231 for mounting the
- the receptacle 4, with which the bucket 1 is attached to the boom head of the excavator, is known per se and need not be described.
- the backhoe bucket 1 consists of individual assemblies
- the middle shell 2 for example, the middle shell 2, the two side shells 31, 32 and the scissor systems 5, 6. These assemblies can be packaged and shipped in the disassembled state and assembled at the receiver, which can be done with numerous
- the double vision system 7 consists of two swivel arms 71, 72 on both sides; 73, 74. Because the four swivel arms
- the pivotable joints 711, 721 are at one Connection piece 75 is mounted to which a pressure motor 76
