Definitions
- the invention relates to a working tool for an earth-moving machine, in particular an excavator, with a digging device designed as a bucket or shovel, which is pivotably arranged on a stick or boom of the earth-moving machine and delimits a receiving space for the material to be removed, and with one arranged on the digging device and as a structural unit with this attachment which can be detached from the handle and which has an additional tool which can be pivoted by means of a pivot drive against the loading opening of the receiving space.
- a digging device designed as a bucket or shovel
- Excavators of this type are known, in which special additional devices for defined work purposes are attached. These have a swivel mechanism which is adapted to the tool and in which a linear drive movement of a hydraulic cylinder which is usually seated on the excavator arm is converted into the tool movement via deflection levers in pin bearings.
- a hydraulic cylinder which is usually seated on the excavator arm is converted into the tool movement via deflection levers in pin bearings.
- the object of the invention is to improve a work tool of the type specified at the outset such that variable use is possible with little assembly effort, without restricting the basic function of the spoon or the shovel.
- the swivel drive has a swivel shaft arranged above the loading opening and extending over more than half its width for a limited swivel movement, and that the additional tool can be exchanged and / or fixed in position on the swivel shaft by means of connecting means.
- the bucket or bucket width can be optimally used to flexibly provide additional tool functions. This does not affect the loading space and there is no need to carry out any modifications outside of the work tool, so that the earth-moving machine is given additional functionality without additional effort.
- the pivot shaft advantageously runs at a distance parallel to the stick bolt provided on the stick for a pivoting movement of the digging device. This means that the entire tool can be easily mounted on the excavator, while, conversely, changing the additional device is not hindered.
- a further improvement in this regard results from the fact that the swivel shaft extends linearly continuously.
- the pivot shaft extends substantially - i.e. with the exception of any end storage points - across the entire width of the loading opening.
- the pivot shaft is axially and / or radially supported at bearing points in the area of the side boundaries of the loading opening. It is also possible for the pivot shaft to be supported in bearing blocks on the upper boundary wall of the receiving space.
- a structurally simple implementation provides that the pivot shaft is an internally mounted tube or a jacket-mounted rod as a rotary element. ment.
- the connecting means can be arranged at connecting points which are distributed discretely along the pivot shaft or are continuous through connection points.
- the swivel shaft can have, in particular, polygonal or polygonal profile elements as connecting means for a non-rotatable positive connection with the additional tool.
- the connecting means are advantageously designed for hanging, plugging on and / or screwing on the additional tool on the pivot shaft.
- a particularly rapid tool change and, at the same time, secure mounting can be made possible in that the connecting means comprise a spigot projecting laterally on the pivot shaft and a receiving shoe arranged on the additional tool, which can be placed on the spigot and fixed by means of a securing element.
- the swivel shaft In order to create additional bearing points, it is possible for the swivel shaft to be linearly composed of several non-rotatably connected sections.
- An embodiment which is also advantageous with regard to the unhindered handle connection of the tool provides that the swivel drive is preferably arranged off-center on an upper boundary wall of the receiving space.
- the swivel drive is advantageously formed by a hydraulic lifting cylinder coupled to the swivel shaft.
- the optional additional tool is equipped with at least one gripping finger or a flap part, in particular a mud flap or a sorting flap. animal sieve is formed.
- a cleaning tool is provided as an additional tool, which can be pivoted into the digging device for cleaning the receiving space. It has surprisingly been found that effective cleaning is possible in that the cleaning device comprises two scrapers that can be swept along the inside of the side walls of the digging device and have an arcuate cutting edge.
- the upper boundary wall of the receiving space is reinforced by a stiffening element.
- FIG. 1 shows a working device for an excavator with a digging bucket and an attachment in a perspective view
- FIG. 2 shows a replaceable auxiliary tool for the attachment in a perspective view
- 5 and 6 a further embodiment of an additional tool for connection to a pivot shaft in a partially sectioned side view and top view; 7 and 8 a cleaning scraper as an additional tool in the released and swiveled-in position in combination with the digging spoon.
- the working tool shown in the drawing essentially consists of a backhoe bucket as digging device 10 and an attachment 12 arranged as a structural unit thereon for a replaceable additional tool 14, 16, 17.
- the spoon 10 has a receiving space 24 for the digging material which is delimited by side walls 18, an upper wall 20 and a lower wall 22.
- a plurality of teeth 28 are arranged on a free cutting edge 26 of the lower wall 22.
- two bearing blocks 30 are provided for a known pivot connection with a stick of an excavator, not shown.
- the bearing blocks 30 have bearing eyes 32 for receiving a stem bolt and bores 34 for articulating a drive piston.
- the attachment 12 comprises a swivel drive 36 designed as a hydraulic cylinder, which is supported on the cylinder side in bearing blocks 38 on the upper boundary wall 20 of the bucket 10. At the hinge end of its piston rod, the hydraulic cylinder 36 is fixedly connected to a pivot shaft 42 via an angled pivot lever 40.
- the pivot shaft 42 runs parallel to the stem bolt (bearing eyes 32) provided on the handle for a pivoting movement of the bucket 10. It extends between the side walls 18 in the upper edge region of the spoon opening 43 over its entire width. 3 and 4, the pivot shaft is formed by a tube 44 which is rotatably mounted on a fixed inner axle rod 46 and is axially supported at its ends on a collar 48 of the axle rod 46. 1 and 2, gripper fingers 14 and a flap-like sorting screen 16 are shown as examples.
- the additional tools 14, 16 can be connected in a rotationally fixed manner to the pivot shaft 42 by means of connecting means 50 for a pivoting movement.
- the connecting means 50 comprise a plurality of screw tabs 52, welded at a distance from one another in pairs on the pivot shaft 42, for a screw connection 54 in combination with a positive connection 56 of the additional tools 14, 16 on the pivot shaft 42. In this way, the additional tools 14, 16 can be replaced quickly the desired work assignment possible.
- the latter is reinforced on the inside in the region of its upper wall 20 by a stiffening element 58 designed as an angle plate.
- the coupling of the bucket 10 with the excavator arm via the bearing blocks 30 does not require any assembly work on the hydraulic cylinder 36. Only its hydraulic connections have to be made via suitable lines.
- the toothed gripping finger 14 is pivoted against the bucket 10 or its receiving opening 43 (FIGS. 3, 4), so that, for example, tree trunks or boulders can be picked up by clamping.
- a sorting sieve according to FIG. 2 60 small portions of the digging material can be discharged from the receiving space 24 of the spoon 10 via its free spaces, while larger portions are retained. Accordingly, a mud flap could also be used to pour out liquid components.
- the named connecting means 50 allow as Quick change system for quick exchange with little handling.
- FIGS. 5 to 8 A further embodiment of the connecting means 50 is shown in FIGS. 5 to 8. Radially projecting spigots 70 are welded to the swivel shaft 42 at the connection points provided, while the additional tool 14, 17 has a corresponding receiving shoe 72, which can be clamped on the spigot 70 and fixed thereon by means of a laterally screwed-in securing bolt 73.
- the gripping finger 14 shown in FIG. 5 is provided with a detachable toothed rail 74 in order to be able to better hold the material to be gripped, for example tree trunks.
- a cleaning device 17 for scraping out the receiving space 24 is provided as an additional tool 17.
- the cleaning device 17 is formed by two flat scrapers 76 which are arranged at a lateral spacing from one another and which are guided abruptly along the inner surfaces of the side walls 18 in order to scrape off adhering dirt.
