Abstract

The bucket (10) of the digging machine is attached to the support arm by a mounting (28) incorporating a compact hydraulic motor (18) directly mounted under the support bracket. The motor is clamped directly between a flange (14) across the top of the bucket and a flange (16) rigidly attached to the mounting. The motor controls the relative spacing of the two flanges and thereby the operating movements of the bucket. The two ends of the motor have profiled flanges which locate into a prepared recess (44) in the bucket flange with one end and into a shaped slot in the rigid flange with the other end. The fittings are secured by screws. The motor can be replaced simply by loosening the screws. The hydraulic lines (34) are fed through the bracket. The motor has a plane flange to bolt to the underside of the bracket.

Description

Die Erfindung betrifft ein Arbeitsgerät, insbesondere einen Baggerlöffel oder dgl., das zur Verbindung mit einem Stiel einer Baumaschine an seiner Oberseite ein mittig angeordnetes Anbauorgan mit Schwenkeinrichtung aufweist, die als Drehmotor mit Gehäuse ausgebildet ist, dessen Welle mit einer Aufnahmeeinrichtung an der Oberseite des Arbeitsgerätes verbunden ist.The invention relates to an implement, in particular a Excavator bucket or the like, which is used to connect a stick to one Construction machine on its top a centrally located Attachment with swivel device that acts as a rotary motor is formed with a housing, the shaft with a Pick-up device on the top of the implement connected is.

Baggerlöffel und insbesondere Grabenräumlöffel sind in aller Regel über hydraulische Kolben-Zylinder-Einheiten am Ende des Baggerlöffelstiels angebracht, so daß Schwenkbewegungen um die Querachse des Löffels ausgeführt werden können. Nachteilig bei derartigen Konstruktionen ist die Tatsache, daß die Hydraulikeinheiten sehr anfällig gegen Beschädigungen im rauhen Einsatzbetrieb sind und deshalb geschützt untergebracht werden müssen. Aufgrund der langen Kraftübertragungswege sind außerdem die an der Grabkante des Löffels wirkenden Kräfte eingeschränkt. Excavator spoons and especially trench clearing buckets are in everyone Rule about hydraulic piston-cylinder units at the end of Excavator stick attached so that swiveling movements around the Transverse axis of the spoon can be executed. A disadvantage of such constructions is the fact that the Hydraulic units very susceptible to damage in the rough Operations and are therefore protected have to. Because of the long power transmission paths are also the forces acting on the grave edge of the spoon are limited.

Ein Grabenräumlöffel der eingangs umrissenen Bauart ist bekannt aus DE-A 42 09 412. Dort ist das Anbauorgan über einen geschweißten Schwenkkopf mit dem Baggerlöffel verbunden, wobei in dem Schwenkkopf ein Drehmotor aufgehängt ist, zu dessen Befestigung ein verhältnismäßig schwacher Flansch dient, der in dem Schwenkkopf befestigt ist. Die Schweißkonstruktion des Schwenkkopfes ist verhältnismäßig anfällig und muß alle vom Baggerlöffel übertragenen Kräfte aufnehmen. Ferner sind keine Vorkehrungen getroffen, die es ermöglichen, den Baggerlöffel gegen einen anderen auszutauschen oder in einfacher Weise an einem anderen Baggerstiel anzubringen.A trench clearing bucket of the type outlined at the beginning is known from DE-A 42 09 412. There the attachment is over a welded swivel head connected to the bucket, where a rotary motor is suspended in the swivel head, to the Attachment serves a relatively weak flange, which in the swivel head is attached. The welded construction of the Swivel head is relatively fragile and must all of the Take up the excavator bucket transmitted forces. Furthermore, there are none Precautions have been taken to allow the backhoe bucket exchange for another or in a simple way to attach another excavator arm.

Der Erfindung liegt die Aufgabe zugrunde, ein Arbeitsgerät der eingangs umrissenen Gattung zur Verfügung zu stellen, dessen Anbauorgan mit Schwenkeinrichtung wesentlich robuster ausgebildet ist und das die Möglichkeit bietet, bei Bedarf problemlos ausgebaut zu werden, um es gegen ein anderes Arbeitsgerät auszutauschen oder an einem anderen Stiel zu befestigen.The invention has for its object a tool to provide the initially outlined genus, its Attachment with pivoting device much more robust is trained and offers the opportunity, if necessary to be easily upgraded to another Exchange tools or on another handle fasten.

Bei einem Arbeitsgerät der angegebenen Bauart wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß das Gehäuse des Drehmotors unmittelbar an der Unterseite des Anbauorgans lösbar befestigt ist.With an implement of the specified type, this task solved according to the invention in that the housing of the rotary motor detachably attached directly to the underside of the attachment is.

Mit dieser Maßnahme ist der Drehmotor ein integriertes Bauteil des Arbeitsgerätes und ersetzt den bisher üblichen, geschweißten Schwenkkopf. Damit übernimmt das Gehäuse des Motors unmittelbar alle zwischen Stiel und Arbeitsgerät wirkenden Kräfte, die wesentlich höhere Werte annehmen können als bei bisher üblichen Konstruktionen mit Schwenkkopf.With this measure, the rotary motor is an integrated component of the implement and replaces the previously used, welded Swivel head. The motor housing takes over immediately all forces acting between the handle and the implement can take on significantly higher values than those previously used Constructions with swivel head.

Die flache Oberseite des Gehäuses des Drehmotors ist so ausgebildet, daß sie an der Unterseite des Anbauorgans anliegt und über Schrauben lösbar mit diesem verbunden ist. Auf diese Weise ist es möglich, das Arbeitsgerät, beispielsweise einen Baggerlöffel oder Grabenräumlöffel, vom Stiel der Baumaschine abzunehmen und innerhalb kürzester Zeit an einem anderen Baumaschinentyp zu befestigen.The flat top of the housing of the rotary motor is like this trained that it bears against the underside of the attachment and is detachably connected to it by screws. To this It is possible to use the implement, for example one Excavator bucket or trench clearing bucket, from the handle of the construction machine to take off and to another within a very short time Fasten construction machine type.

Die Aufnahmeeinrichtung des Arbeitsgerätes besteht in an sich bekannter Weise aus zwei zueinander parallelen, von der Oberseite des Arbeitsgerätes abstehenden Platten, die Aussparungen für den lösbaren Eingriff der Motorwelle haben. Damit besteht die Möglichkeit, den Drehmotor mit wenigen Handgriffen aus der Aufnahmeeinrichtung des Arbeitsgerätes auszubauen, ohne die Verbindung mit dem Anbauorgan zu lösen. An den Drehmotor kann sodann ein anderes Arbeitsgerät angebaut werden, beispielsweise ein Hammer oder eine Abbruchzange.The receiving device of the implement is in itself known manner from two parallel to each other, of the Top of the implement protruding plates that Have cutouts for releasable engagement of the motor shaft. This gives you the option of turning the rotary motor with a few Handles from the receiving device of the implement remove without loosening the connection to the attachment. On the rotary motor can then be attached to another implement such as a hammer or demolition pliers.

Nach einem weiteren Merkmal der Erfindung greift ein Ende der Motorwelle formschlüssig in die Aussparung einer der beiden Platten ein, während das andere Ende der Motorwelle in die als oben offenes Langloch ausgebildete Aussparung der anderen Platte eingesetzt ist, an der dieses Ende über eine Befestigungsplatte festgeschraubt wird. Um bei dieser Befestigungsmöglichkeit den Drehmotor von oben in die Aufnahmeeinrichtung einzusetzen, ist vorgesehen, daß der Abstand der beiden Platten um den aus dem Drehmotor vorstehenden Überstand des formschlüssig in die Aussparung eingreifenden Wellenendes größer ist als die Länge des Gehäuses.According to a further feature of the invention, one end of the Motor shaft in the recess of one of the two Plates one while the other end of the motor shaft is in the as Open slot at the top of the other plate is used at which this end via a mounting plate is screwed tight. To the with this mounting option Insert the rotary motor into the mounting device from above provided that the distance between the two plates by the from the Rotary motor protruding protruding into the Recess engaging shaft end is greater than the length of the housing.

Bei einer anderen Ausführungsform der Erfindung entspricht der Abstand der beiden Enden der Länge des Gehäuses des Drehmotors, dessen Wellenenden im wesentlichen bündig mit den Stirnseiten des Gehäuses abschließen. Die beiden Wellenenden und die daran anliegenden Platten der Aufnahmeeinrichtung werden über Schraubbuchsen miteinander verbunden, die jeweils einen an der Außenseite der Platte anliegenden Flansch aufweisen, der an der Platte lösbar festgeschraubt ist. In another embodiment of the invention, the Distance between the two ends of the length of the housing of the rotary motor, whose shaft ends are essentially flush with the end faces complete the housing. The two shaft ends and the one on them adjacent plates of the receiving device are over Screw sockets connected to each other, one at the Have outside of the plate adjacent flange, which on the Plate is screwed releasably.

Der vorzugsweise hydraulische Drehmotor hat an seiner flachen Oberseite Anschlüsse für hydraulische Leitungen, die durch das Anbauorgan in geschützter Weise zu der Hydraulik der Baumaschine geführt werden können.The preferably hydraulic rotary motor has on its flat Top connections for hydraulic lines through the Attachment in a protected manner to the hydraulics of the construction machine can be performed.

    • Die Figuren 1 bis 4 zeigen ein als Baggerlöffel 10 ausgebildetes Arbeitsgerät, das um eine zur Längserstreckung quer angeordnete Mittelachse schwenkbar mit dem Stiel einer Baumaschine verbunden werden kann. Hierzu ist an der Oberseite des Baggerlöffels 10 eine Aufnahmeeinrichtung 12 fest angebracht, die aus einer vorderen Platte 14 und einer dazu parallelen, hinteren Platte 16 besteht. Zwischen diese beiden Platten 14 und 16 ist ein hydraulischer Drehmotor 18 eingesetzt, der ein Gehäuse 20 aufweist und in den Figuren 5 bis 7 näher dargestellt ist. Das Gehäuse 20 hat eine flache Oberseite 22 mit Gewindebohrungen 24 und ist über Schrauben 26 an der flachen Unterseite eines Anbauorgans 28 befestigt. Das Anbauorgan besteht aus einer flachen, mittels der Schrauben 26 an der Oberseite 22 des Gehäuses 20 befestigten Platte 30, von der zwei parallele Schenkel 32 nach oben abstehen. Mittels dieses Anbauorgans 26 ist der Baggerlöffel 10 am Stiel einer Baumaschine angebracht.Figures 1 to 4 show a designed as an excavator bucket 10 Tool, which is arranged around a transverse to the longitudinal extension Center axis pivotally connected to the handle of a construction machine can be. For this purpose, 10 is on the top of the excavator bucket a receiving device 12 fixed, which consists of a front plate 14 and a parallel rear plate 16 consists. Between these two plates 14 and 16 is a hydraulic rotary motor 18 is used, the housing 20 has and is shown in Figures 5 to 7 in more detail. The Housing 20 has a flat top 22 with threaded bores 24 and is about screws 26 on the flat bottom of a Attachment 28 attached. The attachment organ consists of a flat, by means of the screws 26 on the top 22 of the Housing 20 attached plate 30, of which two are parallel Stand leg 32 upwards. By means of this attachment 26 the bucket 10 is attached to the handle of a construction machine.

    Figur 1 läßt erkennen, daß durch das Anbauorgan 28 hydraulische Leitungen 34 geführt sind, deren Enden zu Anschlüssen 36 an der flachen Oberseite 22 des hydraulischen Drehmotors 18 führen.Figure 1 shows that 28 hydraulic by the attachment Lines 34 are guided, the ends of which lead to connections 36 on the lead flat top 22 of the hydraulic rotary motor 18.

    Beim Ausführungsbeispiel der Figuren 1 bis 8 stehen die Enden 38 und 40 der Welle 42 des Drehmotors 18 über dessen Gehäuse 20 vor. Wenigstens eines der beiden vorstehenden Enden 38 hat zwei zueinander parallele Abflachungen 44, die in den Figuren 1 und 6 zu erkennen sind. Dieses abgeflachte Ende 38 greift formschlüssig in eine entsprechende Aussparung 46 der vorderen Platte 14 ein, mit der dieses Wellenende 38 durch zwei Schrauben 48 gesichert ist.In the exemplary embodiment in FIGS. 1 to 8, the ends 38 and 40 of the shaft 42 of the rotary motor 18 via the housing 20 thereof in front. At least one of the two projecting ends 38 has two parallel flats 44, which in FIGS. 1 and 6 are recognizable. This flattened end 38 engages positively in a corresponding recess 46 of the front Plate 14, with which this shaft end 38 by two screws 48 is secured.

    Die Figuren 3 und 4 zeigen den Baggerlöffel 10 von der Rückseite, wo zu erkennen ist, daß in die hintere Platte 16 eine Aussparung eingearbeitet ist, die ein oben offenes Langloch 50 ist. In dieses Langloch 50 greift das andere Ende 40 der Welle 42 ein. Wie die Figuren 4 und 8 zeigen, ist an diesem Wellenende 40 eine kreisscheibenförmige Befestigungsplatte 52 angebracht, die über Schrauben 54 mit der hinteren Platte 16 fest verbunden ist.Figures 3 and 4 show the bucket 10 from the Back, where it can be seen that in the rear plate 16 a Recess is incorporated, which is an elongated hole 50 open at the top is. The other end 40 of the shaft engages in this slot 50 42 a. As shown in Figures 4 and 8, is at this shaft end 40 a circular disk-shaped fastening plate 52 is attached, which are firmly connected to the rear plate 16 via screws 54 is.

    Aus Figur 8 geht hervor, daß der Abstand der beiden zueinander parallelen Platten 14 und 16 größer ist als die Länge des Gehäuses 20 des Drehmotors 18, und zwar um die Länge des Überstandes des Wellenendes 38. Um den am Anbauorgan 28 hängenden Drehmotor 18 in die Aufnahmeeinrichtung 12 einzubauen, wird der Drehmotor 18 zwischen den beiden Platten 14 und 16 abgesenkt und anschließend rechtwinklig zu dieser Abwärtsbewegung gegen die vordere Platte 14 verschoben, so daß das abgeflachte Wellenende 38 in die Aussparung 46 formschlüssig eingreift. Das andere Wellenende 40 liegt dann in dem Langloch 50; über die Befestigungsplatte 52 wird es mit Hilfe der Schrauben 54 an der hinteren Platte 16 fixiert.From Figure 8 it can be seen that the distance between the two parallel plates 14 and 16 is greater than the length of the Housing 20 of the rotary motor 18, namely by the length of the Projection of the shaft end 38. To the 28 on the attachment to install the hanging rotary motor 18 in the receiving device 12, the rotary motor 18 between the two plates 14 and 16 lowered and then at right angles to it Downward movement against the front plate 14 shifted so that the flattened shaft end 38 in the recess 46 in a form-fitting manner intervenes. The other shaft end 40 is then in the slot 50; About the mounting plate 52, it is with the help of Screws 54 fixed to the rear plate 16.

    Beim Ausführungsbeispiel der Figur 9 entspricht der Abstand der beiden Platten 14 und 16 der Aufnahmeeinrichtung 12 der Länge des Gehäuses 20 des Drehmotors 18, dessen Wellenenden 38 und 40 im wesentlichen bündig mit den Stirnseiten des Gehäuses 20 abschließen. Um in der Aufnahmeeinrichtung 12 den Drehmotor 18 anzubringen, muß dieser lediglich in vertikaler Richtung zwischen den beiden Platten 14 und 16 abgesenkt werden. Sodann werden zwei Schraubbuchsen 56 in die mit einem Gewinde versehenen Enden 38 und 40 der Welle 42 eingeschraubt, wobei die Schraubbuchsen 56 auch in ein entsprechendes Gewinde der beiden Platten 14 und 16 eingreifen. Zur drehfesten Fixierung der beiden Schraubbuchsen 56 an den Platten 14 und 16 dienen Schrauben 58, die durch Löcher eines Flansches 60 gesteckt sind, der von jeder Schraubbuchse 56 absteht. Die Schrauben 58 greifen in nicht weiter dargestellte Gewindebohrungen der beiden Platten 14 und 16 ein.In the embodiment of Figure 9, the distance corresponds to two plates 14 and 16 of the receiving device 12 of length of the housing 20 of the rotary motor 18, the shaft ends 38 and 40 essentially flush with the end faces of the housing 20 to lock. To rotate the rotary motor 18 in the receiving device 12 to attach, it only needs to be in the vertical direction be lowered between the two plates 14 and 16. Then are two screw bushings 56 in the one threaded provided ends 38 and 40 of the shaft 42 screwed, the Screw bushings 56 also in a corresponding thread of the two Intervene plates 14 and 16. For the rotationally fixed fixing of the serve two screw bushings 56 on the plates 14 and 16 Screws 58 which are inserted through holes in a flange 60, which protrudes from each screw bushing 56. The screws 58 grip in threaded holes, not shown, of the two plates 14 and 16 a.
