Description

Bohrkrone für Bohrschrämlader Die Erfindung bezieht sich auf eine Bohrkrone für Bohrschrämlader mit parallel zur Längsachse dieses Laders verlaufenden Ladestegen.Drill bit for drill cutter loader The invention relates to a Drill bit for drill cutter loader with parallel to the longitudinal axis of this loader Loading ramps.

Es sind Bohrkronen bekannt, bei denen die gegen-Überliegenden Schrämmeißelhalter mit parallel zueinander liegenden Stegen verbunden sind. Diese weisen dazu seitlich an den Stegen angebrachte Sockel mit Zähnen auf. Die gelöste Kohle, die durch die Stege seitwärts in den Förderer geschoben werden sollte, wurde durch diese Sockel mitgenommen und gegen die Firste hochgeschleudert, um dann, durch den Anprall zerkleinert, wahllos nach allen Richtungen verteilt zu werden. Es ist ferner eine Bohrkrone in Flügelform bekannt, die in zwei Richtungen gekrümrat ist und bei der das Ende des Flügels ein Schneidmesser aufweist, das im Gegensatz zu dem eigentlichen Flügel entgegengesetzt gekrümmt ist. Auch dieser Messeransatz ist ebenso wie die Sockel an den Stegen die Ursache für das Hochschleudern der mitgenommenen Kohle. Dieser Flügel sollte die Kohle unter einem Winkel von etwa 451 schräg in den Förderer werfen, jedoch wird dieselbe fast lotrecht gegen die Firste geschleudeft Die Erfindung vermeidet diese Nachteile und schafft mit einfachen Mitteln eine Bohrkrone, die die Kohle schonend in den Förderer transportiert.There are drill bits known in which the opposite chipping bit holder are connected with webs lying parallel to one another. These point to the side sockets with teeth attached to the webs. The dissolved coal produced by the Shoulders be pushed sideways into the conveyor, this pedestal was used taken and thrown up against the roof, only to be crushed by the impact, to be randomly distributed in all directions. There is also a drill bit in Known wing shape, which is curved in two directions and in which the end of the Wing has a cutting knife that, in contrast to the actual wing is oppositely curved. This knife attachment is just like the base on the webs the cause of the coal being thrown up. This The wing should throw the coal diagonally into the conveyor at an angle of about 451, however, it is thrown almost perpendicularly against the roof. The invention avoids these disadvantages and creates a drill bit with simple means that the coal gently transported into the conveyor.

Zu diesem Zweck sind die Ladestege von ihrem Befestigungspunkt an der Kronennabe zum Meißelträger hin entgegen der Drehrichtung der Bohrkrone gebogen. Die Kohle wird daher in Richtung des Förderers von den Stegen angehoben und gleitet infolge des Bogens leicht von diesen ab in den Förderer.For this purpose, the loading bars are from their attachment point the crown hub bent towards the bit carrier against the direction of rotation of the drill bit. The coal is therefore lifted off the webs in the direction of the conveyor and slides as a result of the arch, easily from these into the conveyor.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung in Vorderansicht dargestellt. In der Zeichnung bezeichnet 1 die beiden Meißelträger der Bohrkrone. Die von der Nabe ausgehenden, zum Meißelträger gebogenen Stege 2 sind entgegen der durch den Pfeil 7 angezeigten Drehrichtung der Bohrkrone gebogen. Diese Stege 2 werfen die Kohle in den Strebförderer 3, der neben dem Bohrschrämlader 4 mit seiner Kabelzuführung 5 entlang fördert. Mit 6 ist eine schwenkbare Prallwand bezeichnet.An embodiment of the invention is shown in the drawing in a front view. In the drawing, 1 denotes the two bit carriers of the drill bit. The webs 2 extending from the hub and bent towards the bit carrier are bent counter to the direction of rotation of the drill bit indicated by the arrow 7. These webs 2 throw the coal into the face conveyor 3 which, in addition to the drill cutter loader 4, conveys along with its cable feed 5. 6 a pivotal impact wall is designated.
