Description

Die Erfindung betrifft einen Grabenräumlöffel für einen Bagger gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a trench clearing bucket for one Excavator according to the preamble of claim 1.

Ein derartiger Grabenräumlöffel ist aus der DE-A-30 45 496 bekannt.Such a trench clearing bucket is known from DE-A-30 45 496.

Zur Herstellung und zum Freihalten von Straßengräben, welche das von der Straßenoberfläche abfließende Wasser ableiten, ist es bekannt, Baggerlöffel dieser Art im Zuge der Fortbewegung eines Baggers längs des Grabenverlaufs mitzuführen, wobei das Schürfgut unter Ausbildung der Grabenkontur über die hierfür vorgesehene einzige öffnung in das Schürfgefäß aufgenommen wird. Bei solchen Erdbauarbeiten tritt jedoch auch das Problem auf, die zwischen der Straße und dem Graben sich erstreckende Bankette bzw. die gegenüberliegende Böschung mit geeigneter Neigung eben abzuziehen. Hierfür wird üblicherweise ein gesonderter Tieflöffel verwendet, welcher mittels eines doppeltwirkenden Hydraulikzylinders in seiner Neigung bezüglich des Grabens verstellt werden kann. Als nachteilig hierbei wird angesehen, daß somit zwei Löffel erforderlich sind, die für den jeweils auszuführenden Arbeitsgang an dem Baggerausleger eigens angeflanscht werden müssen.To create and keep ditches, which is the water flowing off the road surface derive, it is known to dig in this type of bucket Movement of an excavator along the trench carry with, the prospect under training the trench contour over the only one intended for this purpose opening is received in the scraper. at such earthworks also have the problem on that extending between the road and the ditch Banquets or the opposite embankment to pull off with a suitable inclination. For this will usually a separate bucket is used, which by means of a double-acting hydraulic cylinder adjusted in its inclination with respect to the trench can be. It is considered disadvantageous here that thus two spoons are required, each for the operation to be carried out on the excavator boom have to be specially flanged.

Aus der NL-A-7 116 317 ist ein über eine gerade Schneide bodenseitig schürfender Baggerlöffel bekannt, der sich über geeignete Kopplungsmittel sowohl mit einem Baggerausleger als auch einem Zugseil verbinden läßt. Der rechteckförmig nach oben offene Löffelbereich wird dabei von einem gewölbten Aufhängebügel überspannt.From NL-A-7 116 317 is a straight edge known excavator bucket on the bottom, the suitable coupling agents with both Excavator boom as well as a pull rope can be connected. The spoon area, which is open upwards in a rectangular shape, spanned by a curved suspension bracket.

Die US-A-3 195 747 zeigt einen Baggerlöffel mit einem konkav gekrümmten Boden, an welchen zwei Schürföffnungen angrenzen, so daß in einer Schwenkbewegung in beiden Schnittrichtungen gearbeitet werden kann.US-A-3 195 747 shows an excavator bucket with a concave curved floor, on which two scraper openings adjoin so that in a swivel movement in both Cutting directions can be worked.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, einen Baggerlöffel zu entwickeln, mit dem sich die vorstehend beschriebenen Erdbauarbeiten vereinfacht durchführen lassen.Proceeding from this, the invention is based on the object to develop a backhoe with which simplified the earthworks described above have it carried out.

Zur Lösung dieser Aufgabe wird die im Patentanspruch 1 angegebene Merkmalskombination vorgeschlagen. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.To solve this problem is the in claim 1 specified combination of features proposed. advantageous Refinements and developments of the invention result from the dependent claims.

Erfindungsgemäß wird vorgeschlagen, daß das Schürfgefäß an einer dem Boden gegenüberliegenden Kopfseite eine zweite Schürföffnung zum Abziehen eines Grabenrandstreifens aufweist, wobei die im Umriß rechteckige zweite Schürföffnung durch eine als gerade Schneide ausgebildete freie Randkante einer der ersten Schürföffnung gegenüberliegenden Stirnwand des Schürfgefäßes breitseitig berandet ist. Damit ist es möglich, mit nur einem Löffel in einem fortlaufenden Arbeitsverfahren sowohl den Graben als auch die Bankette in der gewünschten Kontur zu erstellen.According to the invention, it is proposed that that the scraper at one the bottom on the opposite side of the head a second scraper opening for pulling off a trench edge strip, the second prospect, rectangular in outline through a free edge designed as a straight edge one opposite the first prospect End wall of the scraping vessel is bordered on the broad side. It is possible with just one spoon in one ongoing work both digging as well also create the banquets in the desired contour.

Zur Verringerung des manuellen Arbeitsaufwandes läßt sich das im Schleppbetrieb entlang einem Graben mit dem Bagger mitgeführte Schürfgefäß mittels der Kopplungsvorrichtung in seine zwei Funktionsstellungen bringen, in denen jeweils eine der Schürföffnungen zum Räumen des Grabens oder Abziehen des Grabenrandstreifens quer zur Schlepprichtung orientiert ist. Dies kann in vorteilhafter Weise dadurch erfolgen, daß die Kopplungsvorrichtung eine vorzugsweise hydraulisch angetriebene Dreheinheit zur Drehung des Schürfgefäßes um eine senkrecht durch die Ebene der zweiten Schürföffnung verlaufende Drehachse aufweist. In Ergänzung zur Kinematik eines Knickauslegers kann das Schürfgefäß mittels einer Schwenkeinheit der Kopplungsvorrichtung um eine senkrecht zu dem Löffelstiel des Auslegers verlaufende Schwenkachse verschwenkt werden.To reduce manual labor towing along a ditch with the Excavator carried excavator by means of the coupling device bring it into its two functional positions, in each of which one of the scraper openings for clearing digging or pulling the trench edge strip across is oriented to the towing direction. This can be beneficial Way done in that the coupling device a preferably hydraulically driven Rotary unit for rotating the scraper vertically through the plane of the second prospect Has axis of rotation. In addition to the kinematics an articulated boom, the scraper can by means of a Swivel unit of the coupling device by a vertical to the arm of the boom Pivot axis can be pivoted.

Zur einfachen Herstellung einer vorteilhaften Grabenkontur ist es vorgesehen, daß der Boden des Schürfgefäßes rinnenförmig nach außen gewölbt ist. For the simple production of an advantageous trench contour it is provided that the bottom of the scraper is arched outwards.

Das Anschließen der Kopplungsvorrichtung läßt sich dadurch erleichtern, daß das Schürfgefäß eine kopfseitig angeordnete, die Seitenwände unter Freihaltung der zweiten Schürföffnung verbindende Flanschplatte aufweist.The connection of the coupling device can be done facilitate that the scraper a head arranged, keeping the side walls clear has a second scraper opening connecting flange plate.

Vorteilhafterweise ist eine Deckelplatte zum Verschließen der zweiten Schürföffnung vorgesehen. Damit wird insbesondere verhindert, daß abgegrabener Schlamm bei der Bewegung des Schürfgefäßes wieder abfließen kann. Die Handhabung der Deckelplatte läßt sich dadurch erleichtern, daß sie bei rechteckigem Umriß zwei gegenüberliegende, abgekantete Randstreifen zum Aufschieben auf das Schürfgefäß aufweist, wobei die Randstreifen die zugewandten Außenkanten der Seitenwände schwalbenschwanzartig hintergreifen. Dabei ist es weiter von Vorteil, wenn die Deckelplatte über eine Rastverbindung lösbar mit dem Schürfgefäß verbindbar ist.A cover plate for closing is advantageous the second prospect. So that will in particular, prevents mud from being excavated the movement of the scraper can flow again. The handling of the cover plate can be facilitated by that they have two opposing, rectangular shapes folded edge strips to slide on has on the scraper, the edge strips the facing outer edges of the side walls are dovetail-like engage behind. It is further from Advantage if the cover plate has a snap connection is releasably connectable to the scraper.

Zur besseren Ableitung des in das Schürfgefäß verdrängten Aushubs können der Boden und die Stirnwand über ein innenseitig konkav gekrümmtes Wandungsteil bogenförmig miteinander verbunden sein. For better discharge of the displaced into the scraper Excavations can be done through the floor and the bulkhead inside concave curved wall part arched be connected.

Vorteilhafterweise ist das Schürfgefäß mittels eines im Querschnitt abgewinkelten Aussteifungsblechs ausgesteift, welches an seinen Randkanten vorzugsweise durch eine Schweißverbindung fest mit den Seitenwänden und der Flanschplatte verbunden ist und mit seinen Schenkeln von den einander zugewandten Rändern der Schürföffnungen weg schräg nach innen in das Schürfgefaß absteht.The scraper is advantageously by means of a Cross-section of angled stiffening plate, which preferably at its edge a welded connection firmly to the side walls and the flange plate is connected and with its legs from the facing edges of the Scraps open diagonally inwards into the scraper projects.

Die Erfindung umfaßt auch einen Bagger, dessen Ausleger mit einem erfindungsgemäßen Grabenräumlöffel gekoppelt ist.The invention also includes an excavator, the boom of which is coupled with a trench clearing spoon according to the invention.
