  Erweiterungsbohrer für Kerngewinnung. 



   Im Stamm-Patente ist eine    Bohrvorrichtung beschrieben, bei welcher   der schwere Antriebsmotor des Bohrers beim Hochheben des erbohrten Kernes mitgehoben werden muss. Die Bohreinrichtung gestaltet sich aber durch den   staub-und wasserdichten Abschluss   des 
 EMI1.1 
 der Bohrvorrichtung durch das Führungsrohr selbst gestattet, wodurch der Bohrer mit dem Kerne gehoben werden kann, ohne dass sich hieran die Antriebsmechanismen beteiligen. Die Bohrvorrichtung gestaltet sich im vorliegenden Falle bedeutend einfacher und kann infolge ihres geringeren Gewichtes viel leichter gehoben werden. 



   In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiele dargestellt, und zeigt 
 EMI1.2 
 der   Linie. 1-- U.   



   Die Bohrkrone besteht ans zwei   halbkrèisfiirmigen Bügen a,   welche mit dem Bohrrohre b durch Zapfen c drehbar verbunden sind. In den Bögen a sind Segmente d befestigt, 
 EMI1.3 
 einerseits die während des Betriebes rotierende Verrohrung leicht nachgeschoben werden kann, andererseits der Kern   9   bequem im Inneren des Bohrrohres Platz hat. 
 EMI1.4 
 sich die Bögen   a   um ihre Zapfen c und die Bohrdiamanten werden an den Kern   9   gedrilekt, so dass dieser   allmählich zum grossen   Teile abgeschnitten wird. Durch Anheben des Bohrers

 durch Reibung an dieser gehalten wird.

  Extension drill for core extraction.



   In the parent patents a drilling device is described in which the heavy drive motor of the drill has to be lifted when lifting the drilled core. The drilling device is designed, however, through the dust-tight and watertight closure of the
 EMI1.1
 the drilling device is permitted by the guide tube itself, whereby the drill bit with the core can be lifted without the drive mechanisms participating in this. The drilling device is much simpler in the present case and can be lifted much more easily due to its lower weight.



   In the drawing, the subject matter of the invention is shown in an exemplary embodiment and shows
 EMI1.2
 the line. 1-- U.



   The drill bit consists of two semi-circular bends a, which are rotatably connected to the drill pipe b by pins c. In the arches a segments d are attached,
 EMI1.3
 on the one hand, the casing rotating during operation can be easily pushed in, and on the other hand, the core 9 conveniently has space inside the drill pipe.
 EMI1.4
 the arcs a around their pegs c and the drilling diamonds are pressed against the core 9, so that this is gradually cut off to a large extent. By lifting the drill
 EMI1.5
 is held by friction on this.
