Description

Die Erfindung bezieht sich auf einen Schaufelradbagger, insbesondere zur getrennten Gewinnung von in vielen Einzelschichten übereinander gelagerten, verschiedenartigen Mineralien.The invention relates to a bucket wheel excavator, in particular for the separate extraction of stored in many individual layers on top of each other, various minerals.

Es ist allgemein bekannt, Schaufelradbagger mit heb- und senkbarem sowie um eine lotrechte Achse schwenkbarem Schaufelradausleger zur getrennten Gewinnung verschiedenartiger, übereinander gelagerter Mineralschichten zu verwenden. Wenn es sich um eine geringe Anzahl von Schichten, beispielsweise um die Aushaltung eines Tonmittels aus einem Kohlenflöz, handelt, wobei zuerst die Oberkohle, dann das Tonmittel und zuletzt die Unterkohle gewonnen wird, kann der Abbau noch mittels eines nicht zu langen. Schaufelradauslegers einwendfrei erfolgen. Handelt es sich aber um eine größere Anzahl von Schichten. verschiedenartiger Mineralien a., b, z. B. nach Fig. I, die, von, oben beginnend, getrennt gebaggert werden müssen, dann würde der Schaufelradausleger eine ungewöhnlich große Länge erhalten müssen. Hierdurch würde, da das Schaufelrad sich mit seinem Antrieb, in größerer Entfernung von der Schwenkmitte des Baggers befände und entsprechende statische und dynamische Gegengewichte erforderlich wären, das Konstruktions- und Dienstgewicht ganz erheblich erhöht. Auch hat man bereits vorgeschlagen, das Schaufelrad winklig zum Hauptförderband einzubauen. Es ist weiter bekannt, dieses quer zur Auslegerlängsachse gelagerte Schaufelrad im Auslegerkopf heb- und senkbar anzuordnen. Bei der geforderten großen Abtraghöhe würde diese Anordnung ebenfalls eine beträchtliche Erhöhung des Dienstgewichtes zur Folge haben.It is well known, bucket wheel excavators with liftable and lowerable as well as a paddle wheel arm that can be pivoted about a vertical axis for separate extraction to use different, superimposed mineral layers. if it is a small number of shifts, for example holding one Clay medium from a coal seam, with first the upper coal, then the clay medium and finally the lower coal is extracted, the mining cannot yet be done by means of a too long. The bucket wheel boom is made inversely. But is it a greater number of layers. various minerals a., b, z. B. according to Fig. I, which, starting from the top, have to be dredged separately, then the bucket-wheel boom would must have an unusually great length. This would cause the paddle wheel with its drive, at a greater distance from the swing center of the excavator conditions and corresponding static and dynamic counterweights would be required, the construction and service weight increased considerably. Also one already has suggested installing the paddle wheel at an angle to the main conveyor belt. It is on known, this paddle wheel mounted transversely to the longitudinal axis of the boom in the boom head to be arranged so that it can be raised and lowered. With the required large removal height, this arrangement would also result in a considerable increase in the service weight.

Erfindungsgemäß wird eine zweckmäßigere Ausbildung des Schaufelradauslegerkopfes mit Schaufelrad, Antrieb und Abzugsband vorgeschlagen, der durch einen Parallelogrammträger mit der im schwenkbaren Oberbau längs verschiebbaren Laufkatze verbunden ist. Hierdurch wird erreicht, daß infolge der senkrechten Abbaufront die Länge des Radauslegers nicht durch die Anzahl der Schichten bestimmt wird, sondern nur durch die Gesamtabtraghöhe. Der Ausleger wird somit wesentlich kürzer und dadurch das gesamte Dienstgewicht erheblich niedriger. Außerdem behält das Schaufelrad in jeder Höhenlage seine senkrechte bzw. eine bestimmte Lage bei, die man ihm grundlegend gegeben. hat.According to the invention, a more appropriate design of the bucket wheel boom head is achieved with paddle wheel, drive and discharge belt proposed by a parallelogram carrier is connected to the longitudinally displaceable trolley in the swiveling superstructure. Through this it is achieved that as a result of the vertical dismantling front, the length of the wheel arm is not determined by the number of layers, but only by the total removal height. The boom is thus much shorter and thus the total service weight considerably lower. In addition, the paddle wheel retains its vertical position at any altitude or a certain situation that is fundamentally given to him. Has.

In der Zeichnung ist das Wesen der Erfindung in den Fig. 2 und 3 in Stirnansicht bzw. in Draufsicht veranschaulicht.In the drawing, the essence of the invention is shown in FIGS. 2 and 3 in Front view or illustrated in plan view.

Gemäß Fig. 2 und 3 ist auf dem Fahrgestell I der schwenkbare Oberbau 2 mit Ausleger 3 angeordnet. Eine im Oberbau vorgesehene Vorschubkatze 4 trägt einen. Parallelogrammträger 5 mit Hauptförderband 6, welches in bekannter Weise heb- und senkbar ist.According to FIGS. 2 and 3, the swiveling superstructure is on the chassis I. 2 arranged with boom 3. A feed trolley 4 provided in the superstructure carries one. Parallelogram carrier 5 with main conveyor belt 6, which in a known manner lift and is lowerable.

An dem Parallogrammträger 5 ist ein Kopfstück 7 angelenkt, welches das Abzugsband 8 und das Schaufelrad 9 mit dem nicht weiter dargestellten Antrieb träg. Das Schaufelrad: 9 ist mit seiner offenen Schurrenseite dem Abzugshand 8 zugewendet und kann lotrecht, aber auch zum Bagger geneigt angeordnet sein. Der Abbaubetrieb der verschiedenartigen, übereinander gelagerten Mineralien, a, b erfolgt in bekannter Weise im Blocksystem.A head piece 7 is articulated on the parallogram carrier 5, which the take-off belt 8 and the paddle wheel 9 with the drive, not shown further sluggish The paddle wheel: 9 faces the trigger hand 8 with its open chute side and can be arranged perpendicular, but also inclined to the excavator. The mining operation of the different, superimposed minerals, a, b takes place in known Way in the block system.
