Description

Bohrschrämmaschine, mit an Schwenkarmen angebrachten Werkzeugen Die Erfindung bezieht sich auf eine Bohrschrämmaschine, an deren beiden Enden, an höhenverschwenkbaren Armen außerhalb des Maschinenquerschnittes liegende, in Vorschubrichtung arbeitende Bohrschrämwerkzeuge angebracht sind.Drill cutting machine, with tools attached to swivel arms The invention relates to a drill cutting machine, at both ends of which can be pivoted in height Arms outside the machine cross-section, working in the feed direction Drill cutting tools are attached.

Es ist bereits ein Bohrschrämlader bekannt, bei der höhenverschwenkbare Bohrschrämköpfe angeordnet sind. Hierbei waren die verschwenkbaren Bohrschrämköpfe jedoch als zusätzliche Werkzeuge vorgesehen. Diese Maschinen waren äußerst kompliziert und benötigten mindestens vier Bohrkronen.A drill cutter loader is already known in which the height-pivotable Drill cutter heads are arranged. Here were the swiveling drill cutter heads but intended as additional tools. These machines were extremely complicated and needed at least four drill bits.

Diese Bohrschrämlader zu vereinfachen, ist das Ziel der vorliegenden Erfindung und wird dadurch erreicht, daß die Bohrwerkzeuge um die Schwenkarme um mindestens 180° zum Schneiden in beiden Arbeitsrichtungen drehbar gelagert sind.Simplifying these drill cutter loaders is the aim of the present invention Invention and is achieved in that the drilling tools around the pivot arms are rotatably mounted at least 180 ° for cutting in both working directions.

Dadurch werden nur noch zwei Bohrkronen benötigt, die praktisch ohne Mehraufwand die Arbeit der bisher bekannten vier Bohrkronen ausführen.This means that only two drill bits are required, practically without them More effort to carry out the work of the previously known four drill bits.

Besonders in der steilen Lagerung ist die Anordnung der gegeneinander verschwenkbaren Bohrkronen von großem Vorteil, weil mit Sicherheit verhindert wird, daß die Oberkohle in zu großen Stücken hineinfällt und beim Abfallen den Ausbau der unteren Ladestrecke gefährden könnte.The arrangement of the against each other is particularly important in steep storage pivotable drill bits are of great advantage because it is definitely prevented that the top coal falls into it in too large pieces, and when it falls off, the expansion the lower charging path.

In der steilen Lagerung wird der unterhalb des Bohrschrämladers angeordnete Flügelflachförderer nicht benötigt, da die Kohle hier nicht geladen zu werden braucht, sondern frei nach unten rutschen kann.In the steep storage, the one below the drill cutter loader is arranged Flat wing conveyor not required because the coal does not need to be loaded here, but can slide down freely.

Der erfindungsgemäße Bohrschrämlader wird an Hand einer Zeichnung, die zum Teil schematisch ein beliebiges Ausführungsbeispiel darstellt, näher erläutert. Es zeigt Fig.1 den erfindungsgemäßen Bohrschrämlader in einer Ansicht von oben, Fig. 2 einen Strebquerschnitt während der Arbeit des Bohrschrämladers.The drill cutter loader according to the invention is based on a drawing, some of which schematically represents any exemplary embodiment, explained in more detail. It shows Figure 1 the drill cutter loader according to the invention in a view from above, Fig. 2 is a longwall cross-section during operation of the drill cutter loader.

In Fig. 1 sind die Breehbohrkronen mit 1 und l a, deren Arme mit 2 und der Maschinenkörper selber mit 3 bezeichnet. Unterhalb des eigentlichen Maschinenkörpers 3 ist der Flügelflachförderer 4 angeordnet, der von dem Maschinenkörper 3 angetrieben wird und die Aufgabe hat, die durch die Bohrkronen 1 und la hereingewonnene Kohle in den neben den Bohrschrämlader liegenden und diese führenden, schematisch angedeuteten Strebförderer 5 zu transportieren. Der Antrieb erfolgt über eine Maschinenwelle 6 und Zwischenwellen 7 mit Kegelrädern 8 und 9, die nur auf einer Seite gezeichnet sind. Durch die Wellen 7 ist gleichzeitig eine Möglichkeit geschaffen, die Verlagerungsarme 2 um ihre Längsachsen zu verschwenken, so daß die Bohrkronen 1 und 1a die strichpunktiert angedeutete Stellung einnehmen können, um in entgegengesetzter Richtung mit der gleichen Wirkung arbeiten zu können.In Fig. 1, the Breehbohrkronen with 1 and la, the arms with 2 and the machine body itself is designated by 3. Below the actual machine body 3, the flat wing conveyor 4 is arranged, which is driven by the machine body 3 and has the task of recovering the coal recovered by the drill bits 1 and la in the next to the drill cutter loader and leading them, indicated schematically To transport face conveyor 5. It is driven by a machine shaft 6 and intermediate shafts 7 with bevel gears 8 and 9, which are only drawn on one side are. The shafts 7 at the same time create the possibility of the displacement arms 2 to pivot about their longitudinal axes, so that the drill bits 1 and 1a are dash-dotted position indicated can take to in the opposite direction with the to be able to work with the same effect.

In Fig. 2 ist das Prinzip des durch die erfindungsgemäße Bohrschrämlademaschine ermöglichten Gewinnungsvorganges angedeutet, wobei die Bohrkrone 1 die am Liegenden schneidende Bohrkrone 1 und die am Hangenden schneidende Bohrkrone, die mit la bezeichnet ist.In Fig. 2 is the principle of the drill cutter loading machine according to the invention made possible extraction process indicated, with the drill bit 1 lying on the floor cutting drill bit 1 and the drill bit cutting on the hanging wall, denoted by la is.
