Description

Vorrichtung zum Abbau mächtiger Flöze mit breitem Blick, bestehend aus als Hohlstempel ausgebildeten Gehäusen Das Merkmal der im Hauptpatent gekennzeichneten Hohlstempel ist neben ihrer Gestalt ihre Anordnung nebeneinander, so daß eine Abbaufront größerer Länge entsteht. Hierbei muß die Frage der Abführung der gewonnenen Kohle gelöst werden. Bekannt sind Anordnungen von Transportbändern, die am Fuß eines Abbaugerüstes liegen. Diese sind jedoch in Verhiebrichtung angeordnet, was hier unmöglich ist, weil dadurch eine sehr große Zahl solcher Bänder notwendig werden würde.Device for mining thick seams with a broad view, consisting from housings designed as hollow stamps The feature of the one identified in the main patent Hollow stamp is next to their shape their arrangement next to each other, so that a dismantling front greater length arises. Here, the question of the removal of the coal extracted be solved. Arrangements of conveyor belts at the foot of a dismantling scaffold are known lie. However, these are arranged in the direction of prevention, which is impossible here, because this would require a very large number of such tapes.

Erfindungsgemäl.'t wird deshalb, um für ein Abtransportband Raum zu. schaffen, der Fuß der Hoblstempel derart ausgespart, daß die nebeneinanderliegenden Aussparungen der verschiedenen Stempel einen am Stoß entlang führenden Hohlraum ergeben, in dem das Transportband untergebracht werden kann. Um diese Aussparung ohne Schwächung des Stempelfußes vornehmen zu können, wird nach einem weiteren Merkmal der Erfindung der Fuß nach dem Versatz zu verkröpft ausgebildet. Dadurch .ergibt sich als Nebenwirkung der Vorteil, daß das Stempelgewicht sich stets an den Kohlenstoß, anlehnt.In accordance with the invention, there is therefore room for a conveyor belt. create, the foot of the planer stamp so recessed that the adjacent Recesses of the various punches create a cavity leading along the joint result, in which the conveyor belt can be accommodated. To this recess To be able to do without weakening the stamping foot, is after a further feature the invention of the foot formed too cranked after the offset. This gives as a side effect, the advantage that the punch weight is always on the coal face, leans on.

Das Bild zeigt ein Ausführungsbeispiel in Seitenansicht und Grundriß. Bei r ist der Kohlenstoß zu sehen, an den sich die Hohlstempel 3 anlehnen. Hinter ihnen befindet sich der Versatz 2. Die Stempelsegmente ruhen auf dem Fuß 4., in dem der Weg 5 mit dem Transportband 6 angeordnet ist. Durch Schachtwendeln 8 fällt die in jedem Hohlstempel gewonnene Kohle dem Transportband zu, Um zu verhüten, daß infolge zu hohen Druckes der Hohlstempelhohlraum durch die Kohle zugepreßt wird, sind nach einem weiteren Merkmal der Erfindung etwa parallel zum Stoß liegende Leisten 7 angeordnet, die ein zu tiefes Eindringen der Hohlstempelkanten in die Kohle verhüten.The picture shows an embodiment in side view and plan. At r, the coal face can be seen on which the hollow punches 3 are leaning. Behind they are offset 2. The stamp segments rest on the foot 4., in where the path 5 with the conveyor belt 6 is arranged. Falls through shaft spirals 8 the coal obtained in each hollow punch to the conveyor belt, in order to prevent that as a result of excessive pressure, the hollow punch cavity is pressed shut by the carbon, are, according to a further feature of the invention, strips lying approximately parallel to the joint 7 arranged, which prevent the hollow punch edges from penetrating too deeply into the coal.

Durch mehr oder weniger vorzunehmendes Beseitigen der vor diesen Leisten anstehenden Kohle kann der Vorschub der Hohlstempel beeinflußt werden.By more or less removing the bars in front of these bars pending coal, the advance of the hollow punch can be influenced.

Die Abbaumaschine zieht in jedem Stempel zunächst eine Kohlenschicht zwischen den Leisten 7 ab und kann dann zunächst über dem Förderer 6 bis zum nächsten Hohlstempel zur weiteren Arbeit 'fahren, abwartend, ob sich der vorhergehende Stempel @-orarbeitet infolge des Versatzdruckes beispielsweise.The mining machine first pulls a layer of coal in each punch between the bars 7 and can then first over the conveyor 6 to the next Hollow stamp for further work ', waiting to see whether the previous stamp @ -orworks as a result of the offset pressure, for example.

Geschieht das nicht, muß später auch die vor den Leisten 7 stehende Kohle durch die Maschine fortgenommen «-erden.If this does not happen, the one in front of the strips 7 must also be used later Coal removed by the machine.
