Einrichtung an Gesteinbohrhämmern zur Verhinderung des Staubaufwirbeins. Patentiert im Deutschen Reiche vom 15. Oktober 1920 ab.Device on rock drill hammers to prevent dust from being whirled up. Patented in the German Empire on October 15, 1920.
Die Staubbelästigung- beim Arbeiten mit durch Druckluft betriebenen Gesteinbohrhämmern rührt wesentlich daher, daß die Abluft das austretende Bohrmehl erfaßt und verwirbelt. Der Erfindung gemäß soll dieser Umstand dadurch vermieden werden, daß die Auspufflöcher nicht mehr, wie es bisher üblich ist, senkrecht zur Bohrhammerachse ausmünden, sondern daß sie von innen nach ίο außen schräg rückwärts gerichtet sind.The dust nuisance - when working with rock drills operated by compressed air stems essentially from the fact that the exhaust air captures and swirls the emerging drill dust. According to the invention, this circumstance is to be avoided in that the exhaust holes are no longer, as was previously the case open perpendicular to the hammer drill axis, but that they are directed obliquely backwards from the inside to the outside.
In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the invention is shown in one embodiment.
Im Zylinder b des Bohrhammers arbeitet der Kolben a. Er besitzt zwei Auspufflöcher d und i, die schräg rückwärts gerichtet sind, so daß die Abluft in eben derselben Richtung abgeht, also vom Bohrloch weggerichtet ist. Piston a works in cylinder b of the hammer drill. It has two exhaust holes d and i, which are directed obliquely backwards, so that the exhaust air goes out in the same direction, that is, is directed away from the borehole.
