Abstract

For a device according to DE...(1149), the carrying position of the bucket on the way from the digging location to the emptying location is improved (Fig. 3). <IMAGE>

Description

Einrichtung für Löffelbagger Device for backhoe excavators

Die Erfindung betrifft eine Einrichtung für Löffelbagger nach DE...(Anmeldung 1149 vom 12.11.1982). Diese weist zwischen Ober-und Unterarm ein Wendegetriebe auf, dessen Gehäuse als eine zum Basishebel parallel geführte Zwischenkoppel dient. An ihr ist ein Löffelbasislenker angelenkt, der die Basis für den Löffel auf dem Transportweg vom Grabort zum Entleerort und zurück parallel zur Zwischenkoppel führt.The invention relates to a device for backhoe excavators according to DE ... (registration 1149 of November 12, 1982). This has a reversing gear between the upper and lower arm, whose housing serves as an intermediate coupling which is guided parallel to the base lever. At A bucket base link is articulated to it, which is the base for the bucket on the transport route from the burial site to the emptying site and back parallel to the intermediate paddock.

Die gleichbleibende Lage des Löffels auf dem Transportweg kann besonders bei gekrümmtem Weg zu Verlust an Grabgut führen. Eine bessere Traglage wird durch die Löffelbasis behindert, deren Laye zu Beginn des Transportweges wegen gestreckter Lage des Löffelbasislenkers nicht ausreichend veränderbar ist.The constant position of the spoon on the transport route can be particularly lead to loss of grave material if the path is curved. A better position is achieved through the base of the spoon is obstructed, the lay of which is stretched at the beginning of the transport route The position of the bucket base link cannot be changed sufficiently.

Aufgabe der Erfindung ist es, die Traglage auf dem Transportweg zunehmend zu verbessern und die Behinderung durch die Löffelbasis abzubauen.The object of the invention is to increase the support layer on the transport route to improve and reduce the obstruction by the spoon base.

Diese Aufgabe wird dadurch gelöst, daß die Löffelbasis auf dem Transportweg zunehmend aus der Parallellage zur Zwischenkoppel in eine angehobene Traglage gedreht wird. Das kann dadurch geschehen, daß der Löffelbasislenker als Hydraulikzylinder ausgebildet wird, dessen Kolbenstange während der Transportbewegung allmählich eingezogen und am Entleerort für den Rücklauf wieder ausgefahren wird. Die Aufgabe kann auch dadurch gelöst werden, daß der Anlenkpunkt des Löffelbasislenkers an der Zwischenkoppel durch einen an der Zwischenkoppel gelagerten Verstellhebel kraftschlüssig verstellbar ist.This object is achieved in that the spoon base on the transport route increasingly rotated from the parallel position to the intermediate coupling in a raised support position will. This can be done by using the bucket base link as a hydraulic cylinder is formed, the piston rod gradually retracted during the transport movement and is extended again at the emptying point for the return. The task can too be solved in that the articulation point of the spoon base link on the intermediate coupling adjustable with a force fit by means of an adjusting lever mounted on the intermediate coupling is.

Diese Lösungen haben den Vorteil, daß ein überfüllter Löffel weniger Grabgut verliert, ohne daß die verbesserte Traglage durch die Löffelbasis behindert wird. Die Traglage kann auch für einen Teilweg automatisch ein- und ausgeschaltet werden, und bleibt, falls sie nicht benötigt wird, ausgeschaltet.These solutions have the advantage that there is one less crowded spoon Grave material loses without the improved support position hindered by the spoon base will. The support layer can also be switched on and off automatically for part of the way and remains switched off if it is not needed.

In den Zeichnungen sind Ausführungsbeispiele dargestellt.Exemplary embodiments are shown in the drawings.

Fig. 1 zeigt eine Ausführungsform mit als Hydraulikzylinder ausgebildetem Löffelbasislenker.Fig. 1 shows an embodiment with designed as a hydraulic cylinder Bucket base link.

Fig. 2 zeigt eine Ausführungsform mit einem Verstellhebel an der Zwischenkoppel schematisch in mehreren Phasen, beginnend mit Grabanfangs- und gestrichelt Grabendlage beide ohne Verstellung, während des Weges dann gestrichelt die Grabendlage und ausgezogen die durch die Verstellung bewirkte Traglage, die in den weiteren Phasen noch verbessert wird.Fig. 2 shows an embodiment with an adjusting lever on the intermediate coupling schematically in several phases, starting with the beginning of the grave and the end of the grave with dashed lines both without adjustment, during the way then dashed the trench end position and pulled out the bearing position caused by the adjustment, which is further improved in the further phases will.

Fig. 3 zeigt eine Ausführungsform mit anders ausgebildetem Verstellhebel und mit der gesamten Einrichtung nach DE...(1149) in drei Phasen, in denen auf Traglage verstellt ist, und am Entleerort gestrichelt die Rückstellung auf Parallellage für den Rücklauf.Fig. 3 shows an embodiment with a differently designed adjusting lever and with the entire device according to DE ... (1149) in three phases, in which on the support position is adjusted, and at the emptying point the reset to parallel position for the rewind.

Der Löffel 1 ist an der Löffelbasis 2 angelenkt und wird durch den Grabzylinder 3 über einen Zwischenhebel 4 und einen Lenker 5 aus der Grabanfangslage in die gestrichelte Grabendlage gedreht (Fig. 2).The spoon 1 is hinged to the spoon base 2 and is through the Digging cylinder 3 via an intermediate lever 4 and a link 5 from the digging start position rotated into the dashed trench end position (Fig. 2).

Die Löffelbasis 2 wird durch den Unterarm 6 und den Hubzylinder 9 über das Wendegetriebe 10 auf einem geradlinigen Transportweg bewegt.The spoon base 2 is supported by the forearm 6 and the lift cylinder 9 Moved via the reversing gear 10 on a straight transport path.

In Fig. 1 ist der Löffelbasislenker als Hydraulikzylinder 18 mit Kolbenstange 19 ausgebildet und in ein- und ausgezogener Stellung gezeichnet.In Fig. 1, the spoon base link is a hydraulic cylinder 18 with a piston rod 19 formed and drawn in the retracted and extended position.

In Fig. 2 und 3 ist der Löffelbasislenker 7 an einem an der Zwischenkoppel 8 gelagerten Verstellhebel 11 bzw. 12 angelenkt und durch den Verstellzylinder 13 bzw. 14 verstellbar.In Fig. 2 and 3 the spoon base link 7 is on one of the intermediate coupling 8 mounted adjusting lever 11 or 12 and articulated by the adjusting cylinder 13 or 14 adjustable.
