Description

Der Endbohrer besteht aus einem seitlich offenen, bügelartigen Fassungsraum für das Bohrgut, dessen unten sich kreuzende Enden in spitze Bohrschaufeln auslaufen .und der aus einem einzigen Blechstück hergestellt werden kann. Die Bohrerstange führt in der Längsrichtung durch den Rahmen und ist am unteren, vorstehenden Ende als Vor- und Zentrierbohrer ausgebildet.The end drill consists of a laterally open, bracket-like space for the Drilled material, the ends of which intersect at the bottom run out into pointed drill blades. And the out a single piece of sheet metal can be produced. The drill rod leads in the longitudinal direction through the frame and is at the lower, protruding end as before and Center drill formed.

Gegenüber den bekannten Erdbohrern laut einer britischen Patentschrift und amerikanischen Patentschriften zeigt der neue Erdbohrer folgende wesentliche Neuerungen: Den aus einem einzigen Blechstück herstellbaren bügelartigen Fassungsrahmen samt Bohrschaufeln mit Spitzen; das Kreuzen der unteren, in die Bohrschaufeln auslaufenden Rahmenenden, welche dem Bohrgut eine freiliegende Gleitbahn zum Fassungsraum bieten;Compared to the well-known auger according to a British patent and American Patent specifications, the new auger shows the following major innovations: The bracket-like mounting frame, which can be produced from a single piece of sheet metal, including Pointed drill blades; the crossing of the lower ones ending in the drill blades Frame ends, which offer the cuttings an exposed slide to the mounting space;

ao die baggerartige Angriff stellung der Bohrschaufeln, welche leicht durch Rippen verstärkt werden können, die an den Schaufelspitzen als vorstehende Zähne endigen; den weiten Durchgangsraum zwischen den Bohr-ao the excavator-like attack position of the drill blades, which can be easily reinforced by ribs that end at the blade tips as protruding teeth ; the wide passage space between the drilling

S5 schaufeln und Rahmenwänden, welcher auch größere Steine leicht durchläßt; die nach oben sich verjüngende Form des Fassungsrahmens, welche das Herausziehen des Bohrers erleichtert; die Stellung der Schneidkanten des Rahmens, derart, daß beim Herausziehen des Bohrers etwaige Hindernisse durch Drehen leicht beseitigt werden können; die freie Lage des Fassungsraumes und der Bohrschaufeln, womit ein leichtes und rasches Entleeren und Reinigen ermöglicht wird; die Ausbildung des unteren Endes der in der Längsrichtung durch den Rahmen geführten Bohrstange als Vor- und Zentrierbohrer.S5 shovels and frame walls, which one too allows larger stones to pass through easily; the shape of the frame, which tapers towards the top, which facilitates the extraction of the drill; the position of the cutting edges of the Frame, so that when pulling out the drill any obstacles by turning can be easily eliminated; the free position of the storage space and the drilling blades, which enables easy and quick emptying and cleaning; training of the lower end of the boring bar guided in the longitudinal direction through the frame as Pilot and center drill.
