Description

Die Erfindung bezieht sich auf ein Schälschrappergefäß mit einer an mindestens einer Stirnkante seiner kohlenstoßseitigen Wand in Gefäßhöhe angeordneten Schälkante aus einer Schneide 5 oder einzelnen Messern. Für eine weitgehende Anwendungsmöglichkeit der Schälschrappergefäße ist es notwendig, daß diese möglichst unempfindlich gegen Gebirgsstörungen sind. Zu den unangenehmsten Gebirgsstörungen nach den Sätteln und MuI-den gehören scharfe Sprünge im Liegenden der Lagerstätte oder gar Überschiebungen.The invention relates to a scraper vessel having one of at least one The front edge of its wall on the coal joint side, arranged at the level of the vessel, is made from a cutting edge 5 or single knives. For a wide range of applications For the scraper vessels, it is necessary that they are as insensitive as possible to mountain disturbances. The most uncomfortable Mountain faults after the saddles and mules include sharp jumps in the lying area Deposit or even thrust.

Abb. ι zeigt einen derartigen treppenartigen Sprung L-M des Liegenden. Schrapper üblicher Bauart können derartig hohe, stufenförmige Störungen nicht überwinden, selbst wenn sie —■ wie bekannt— an der Unterkante kleine Abschrägungen oder abgeschrägte Messer aufweisen.Fig. Ι shows such a step-like jump LM of the lying person. Commonly designed scrapers cannot overcome such high, stepped disturbances, even if they - as is known - have small bevels or beveled knives on the lower edge.

Es sind schon Kohlengewinnungsgeräte bekannt mit messerartigen Lösewerkzeugen, bei denen die Messerschneiden spitz zulaufen und die einzelnen Messerspitzen so angeordnet sind, daß sie nicht auf einer Geraden liegen.There are already coal extraction devices known with knife-like loosening tools in which the Knife edges are tapered and the individual knife tips are arranged so that they do not open lie in a straight line.

Bei einem bekannten hobelartigen Kohlengewinnungsgerät hat man bereits die Kante der Schneide nach hinten geneigt verlegt und die Schneidkante außerdem um ein kurzes Stück nach unten zur oberen Kante gegenläufig verlängert. Dabei befindet sich die in Arbeitsrichtung weisende Spitze der Schneidkante tief unten, etwa in Höhe des Liegenden, so daß lediglich der obere Schneidenschenkel als Lösewerkzeug wirkt und der untere als Führung auf dem Liegenden dient. Diese und ähnliche bekannten Bauformen eignen sich jedoch nicht zum Durchfahren von Gebirgsstörungen, da sie leicht an scharfen Sprüngen hängenbleiben.In a known plane-type coal extraction device, one already has the edge of the cutting edge inclined to the rear and the cutting edge also a short distance down to the top Edge extended in the opposite direction. The tip of the pointing in the working direction is located Cutting edge deep down, approximately at the level of the lying, so that only the upper edge of the cutting edge acts as a release tool and the lower one serves as a guide on the lying person. These and similar well-known However, designs are not suitable for driving through mountain faults because they are light get caught on sharp cracks.

Um auch Sprünge u. dgl. Störungen durch Schälschrappergefäße überwinden zu können, wird gemäß der Erfindung vorgeschlagen, daß die Schälkante in Form eines in seiner Ebene um 900 geschwenkten V, dessen Spitze in Schälrichtung weist, ausgebildet ist.In order to overcome also jumps u. Like. Disturbances by Schälschrappergefäße, the invention is proposed in accordance with that the peeling edge in the form of an in its plane 90 pivoted 0 V, whose tip points in the peeling direction, is formed.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt:An exemplary embodiment of the subject matter of the invention is shown in the drawing:

Abb. ι und 2 zeigen in Seitenansicht bzw. Draufsicht ein Schrappergefäß mit etwa symmetrisch ausgebildeten Schneiden. >Das Gefäß besteht aus den Seitenwänden 1 und 2, die durch Holme 3 miteinander verbunden sind. Die schneidende Schälkante ist mit den Messern 4 bis 7 besetzt, die V-förmig angeordnet sind.Fig. Ι and 2 show a side view and plan view a scraper vessel with roughly symmetrical cutting edges. > The vessel consists of the side walls 1 and 2, which are connected to one another by spars 3. The cutting edge is occupied with the knives 4 to 7, which are arranged in a V-shape.
