Rotationserdbohrer.
EMI1.1
Die Erfindung ist darin gelegen, dass sämtliche Flügel auf derselben Flachseite des Werkzeuges angeordnet sind.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel des unter Schutz gestellten Rotationserdbohrers, und zwar zeigt Fig. 1 eine Seitenansicht desselben und Fig. 2 die untere Endansicht.
Oberhalb des Vorbohrers a sind auf derselben Flachseite des Werkzeuges b drei Flügelbohrer c, d, e in Stufen derart übereinander angeordnet, dass die Ausladung dieser Flügel der Reihe nach von unten nach oben an Grösse zunimmt. Die Zahl der Flügel richtet sich nach der Beschaffenheit des zu bohrenden Gebirges und nach den Abmessungen des zu erzielenden Bohr-

Rotary earth auger.
EMI1.1
The invention is based on the fact that all the wings are arranged on the same flat side of the tool.
The drawing illustrates one embodiment of the protected rotary earth auger, with Fig. 1 being a side view thereof and Fig. 2 being the bottom end view.
Above the pre-drill a, three wing drills c, d, e are arranged in steps one above the other on the same flat side of the tool b in such a way that the projection of these wings increases in size one after the other from bottom to top. The number of blades depends on the nature of the rock to be drilled and the dimensions of the drilling to be
