sehen Kolben-Zylinder-Einheit.see piston-cylinder unit.
Bei dem Grabenräumlöffel 5 nach den F i g. 1 bis 3 ist zwischen den seitlichen Trägern 1,2 eines Löffelstiels an dessen vorderem Ende um die Schwenkachse 3 ein Tragstück 4 schwenkbar gelagert. Das Tragstück 4 für den Löffel 5 weist einen zweiteiligen Hebe1 auf, dessen obere Hebelarme 6 durch Koppeln 7 mit Laschen 8 gelenkig verbunden sind, die an den se.ilichen Trägern 1, 2 des Löffelstiels gelenkig gelagert sind. Mit den Laschen 8, die Teil eines den Löffel 5 verschwenkenden Vier-Geienk-Systems sind, ist in üblicher Weise cie Kolbenstange einer hydraulischen Kolben-Zylinder-Einheit gelenkig verbunden.In the case of the ditch clearing bucket 5 according to FIGS. 1 to 3, a support piece 4 is mounted pivotably about the pivot axis 3 between the lateral supports 1, 2 of a dipperstick at its front end. The support piece 4 for the spoon 5 has a two-part lift 1 , the upper lever arms 6 of which are articulated by coupling 7 with tabs 8 which are articulated on the se.ilichen supports 1, 2 of the spoon handle. The piston rod of a hydraulic piston-cylinder unit is articulated in the usual way with the brackets 8, which are part of a four-joint system which swivels the spoon 5.
Der Löffel 5 ist an seiner der Schneide 9 gegenüberliegenden Seite durch einen aus einem Rohr bestehenden Träger 10 ausgesteift. Der Träger 10 ist mittig mit zwei etwa dreiecksförmigen Laschen 11, 12 versehen, die den unteren Arm des Tragstücks 4 gabelförmig einfassen. Das untere Ende des Tragstücks 4 weist ein Zahnradsegnient 13 auf, das durch eine zwischen den Laschen 11, 12 befindliche Aussparung in das Innere des rohrförmigen Trägers 10 hineinragt- In den Laschen 11,12 ist ein Lagerbolzen 14 gelagert, der die Mittelachse des Zahnradsegments 13 bildet.The spoon 5 is on its side opposite the cutting edge 9 through a tube existing beam 10 stiffened. The carrier 10 is centered with two approximately triangular tabs 11, 12 provided, which enclose the lower arm of the support piece 4 in the shape of a fork. The lower end of the support piece 4 has a gear wheel segment 13, which through a recess located between the tabs 11, 12 in the interior of the tubular carrier 10 protrudes in the tabs 11,12 a bearing pin 14 is mounted, the the central axis of the gear segment 13 forms.
In dem rohrförmigen Träger 10 ist eine Zahnstange 15 gleitend längsverschiebiich geführt, die sich mit der Verzahnung des Zahnsegments 13 im Lingriff befindet. Die Zahnstange 15 ist mit einer Kolbenstange 16 einer hydraulischen Kolben-Zylinder-Einheit 17 gelenkig verbunden, deren Zylinder mit einer den rohrförmigen m Träger 10 schließenden Stirnwand 18 verbunden ist. Schläuche 19,20 dienen der Kolben-Zylinder-Einheit 17 zur Druckmittelzu- und -abführung.A toothed rack 15 is guided in a longitudinally displaceable manner in the tubular carrier 10 and is in mesh with the toothing of the toothed segment 13. The rack 15 is a hydraulic piston-cylinder unit 17 pivotally connected to a piston rod 16, whose cylinder is connected to a tubular carrier 10 m-closing end wall 18. Hoses 19, 20 serve the piston-cylinder unit 17 for supplying and removing pressure medium.
Bei dem Ausführungsbeispiel nach Fig.4 ist die Zahnstange 15 zwischen den Stirnseiten von Kolbenstangen 21,22 eingespannt, wobei die Kolben-Zylinder-Einhei* 17 Plungerzylinder 23,24 aufweist.In the embodiment of Figure 4 is the Toothed rack 15 clamped between the end faces of piston rods 21,22, the piston-cylinder unit 17 having plunger cylinders 23,24.
Die Druckmittelschläuche 19, 20 können in der strichpunktierten Weise miteinander verbunden sein, ohne daß die Plungerzylinder 23,24 an eine Druckmittelquelle angeschlossen sind. Bei dieser Ausführungsform ist in der die Plungerzylinder 23, 24 verbindenden Leitung ein elektrisch betätigbares Wegeventil 25 angeordnet. Gibt das Wegeventil 25 die Verbindung zwischen den Zylinderräumen der Plungerzylinder 23, 24 frei, läßt sich der Grabenräumlöffel 5 in die gewünschte Stellung verschwenken. Durch Schließen des Wegeventils 25 wird die eingestellte Schwenkstellung fixiertThe pressure medium hoses 19, 20 can be connected to one another in the dash-dotted manner, without the plunger cylinders 23, 24 being connected to a pressure medium source. In this embodiment, the plunger cylinders 23, 24 are connected Line an electrically operated directional valve 25 is arranged. Is the directional control valve 25 the connection between the cylinder spaces of the plunger cylinder 23, 24 free, the ditch clearing bucket 5 can be in the Swivel the desired position. By closing the directional control valve 25, the set pivot position is reached fixed
Bei dem Ausführungsbeispiel nach F i g. 5 ist die Zahnstange 15 beidseits mit Plungerzylindern 26, 27 versehen. In die Plungerzylinder 26, 27 greifen Kolben 28, 29 ein, die auf den Stirnscheiben 30, 31 des rohrförmigen Trägers 10 befestigt sind.In the embodiment according to FIG. 5 is the rack 15 with plunger cylinders 26, 27 on both sides Mistake. Pistons 28, 29 engage in the plunger cylinders 26, 27 and are mounted on the end disks 30, 31 of the tubular carrier 10 are attached.
Die Zahnstange 15 weist zumindest in ihren Endbereichen einen dem inneren Rohrquerschnitt entsprechenden Querschnitt auf, so daß sie ohne zusätzliche Führungseinrichtungen in dem Träger 10 geführt ist.The toothed rack 15 has, at least in its end regions, an inner pipe cross-section corresponding cross-section so that they can be in the carrier 10 without additional guide devices is led.

Aufgabe der Erfindung ist es daher, einen Grabenräumlöffel nach dem Oberbegriff des Patentanspruchs 1 zu schaffen, der sich bei raumsparender und verdeckter Anordnung der Kolben-Zylinder-Einheit um seine Querachse in die jeweils gewünschte Arbeitsstellung verschwenken läßt.is moving trench clearing bucket with a locking device is provided which blocks the lever of the trench clearing bucket pivoting the cylinder in its vertical position can only take the position that adjusts itself due to its own weight
The object of the invention is therefore to create a ditch clearing spoon according to the preamble of claim 1, which can be pivoted about its transverse axis into the desired working position with a space-saving and concealed arrangement of the piston-cylinder unit.
