Abstract

Eine Einrichtung zum Abstreifen von Bohrgut aus den Zwischenräumen (82), die zwischen benachbarten Gängen einer Wendelrippe (52) eines Erdbohrers (48) liegen, wird eine Abstreifeinrichtung (44) vorgeschlagen, die einen Abstreifer (80) aufweist, der zwischen einem zwischen die Wendelrippe (52) eingreifenden Arbeitsstellung und einer außerhalb der lichten Kontur des Erdbohrers (48) liegenden Ruhestellung bewegbar und zusätzlich parallel zur Bohrerachse verschiebbar ist. Hat das mit der Abstreifeinrichtung versehene Bohrgerät einen Bohrrohrantrieb, so ist das Abstreifteil (80) durch eine Zugangsöffnung (78) bewegbar, die in einem mit dem oberen Ende des Bohrrohres (46) verbundenen Antriebsrohr (36) vorgesehen ist.
