Description

Die Erfindung bezieht sich auf Gesteinsschlangenbohrer mit in einem Schlitz des Bohrerschaftes auswechselbar angeordneter Bohrerldinge. Das Wesen der Erfindung wird in der S im Anspruch gekennzeichneten, zwecks Ermöglichung eines ungehinderten Abflusses des Bohrmehls getroffenen besonderen Ausbildung des Bohrers gesehen.The invention relates to rock auger bits with in a slot in the drill shank interchangeably arranged drill bits. The essence of the invention is characterized in the S in the claim, for the purpose of enabling an unimpeded drainage of the drill dust hit special training of the Seen drill.

Auf der Zeichnung ist der Erfindungsgegenstand dargestellt.The subject of the invention is shown in the drawing.

Abb. ι ist eine Stirnansicht des Bohrers mit oberhalb der Befestigungsstelle quergeschnittener Klinge;Fig. Ι is an end view of the drill with a cross section above the attachment point Blade;

Abb. 2 und 3 sind um 90 ° gegeneinander versetzte Seitenansichten des Bohrers (Abb. 3 mit längsgeschnittener Klinge).Fig. 2 and 3 are side views of the drill offset from one another by 90 ° (Fig. 3 with lengthwise cut blade).

Der Bohrerschaft e ist zu einem kegelförmigen Zapfen b ausgebildet. Dieser ist mit einem Schlitz versehen, welcher auch, in den hinter dem Zapfen befindlichen, die Schraubengänge tragenden Teil des Bohrerschaftes hineinreicht. In diesen Schlitz wird die Bohrerklinge a eingeführt und darin mittels eines durch, sie und den Zapfen b hindurchgeführten Schraubenbolzens f befestigt. Die Versteifungen c und d der als Beispiel gewählten plattenartigenKlingea können, wie dargestellt, an die Schraubengänge des Schaftes e anstoßen oder in Aussparungen derselben eingreifen.The drill shank e is formed into a conical pin b . This is provided with a slot which also extends into the part of the drill shaft which is located behind the pin and carries the screw threads. The drill blade a is inserted into this slot and fastened therein by means of a screw bolt f passed through it and the pin b . The reinforcements c and d of the plate-like blade a chosen as an example can, as shown, abut the screw threads of the shaft e or engage in recesses thereof.
