Description

Die Erfindung betrifft eine Staubabsaugevorrichtung für Aufbruchbohrhämmer, bei welcher in bekannter Weise ein unter der Wirkung eines Ejektors stehendes Sammelgefäß gegen die Bohrlochinündung gelegt wird. Dieses Sammelgefäß wird in ebenfalls bekannter Weise durch das Treibmittel gegen die Bohrlochmündung angelegt, indem der Träger des Gefäßes plungerartig in der Spannsäule, deren Spannung durch Druckluft geschieht, gelagert ist. Neu ist, daß der so gelagerte Träger des Sammelgefäßes gleichzeitig das E'inströmungsrohr für den Ejektor ist; es wird dadurch eine wesentlich vereinfachte und leichtere Bauart der Vorrichtung erzielt.'The invention relates to a dust extraction device for demolition hammers, at which, in a known manner, is a collecting vessel under the action of an ejector is placed against the borehole mouth. This collection vessel is also in known manner applied by the propellant against the borehole mouth by the Carrier of the vessel plunger-like in the tensioning column, whose tension is done by compressed air, is stored. What is new is that it is stored in this way Carrier of the collecting vessel at the same time the E'instr flow tube for the ejector is; this makes it a much simplified and lighter type of device achieved. '

In der Zeichnung ist die Erfindung teils in Ansicht, teils im Schnitt dargestellt.In the drawing, the invention is shown partly in view, partly in section.

Die Aufbruchbohrmaschine α wird mittels der Spannsäule b, c vorgetrieben. Der Teil c der Spannsäule führt sich mit dem Kolben d in dem Teil b, der als Zylinder dient. Der Staub aus dem Bohrloch wird von dem Gefäß e aufgenommen und durch den Ejektor / abgeführt. Das Sammelgefäß e ist mit dem Ejektor körperlich vereinigt, und das Zuströmungsrohr g des Ejektors ragt in das Innere der mit Druckluft gespeisten Spannsäule b, c hinein, aus der es seine Betriebsluft empfängt. Es ist bei h in der Spannsäule dicht geführt, so daß es plungerartig eingebaut ist und nach Maßgabe der Beaufschlagung aus der Spannsäule herausgetrieben wird. Hierbei wird dann das Sammelgefäß e gegen die Bohrlochmündung dicht angelegt.The break-open drill α is advanced by means of the tensioning column b, c. Part c of the tensioning column leads with piston d in part b, which serves as a cylinder. The dust from the borehole is picked up by the vessel e and discharged through the ejector /. The collecting vessel e is physically united with the ejector, and the inflow pipe g of the ejector protrudes into the interior of the compressed air-fed clamping column b, c from which it receives its operating air. It is tightly guided in the tensioning column at h , so that it is installed like a plunger and is driven out of the tensioning column according to the impact. In this case, the collecting vessel e is then placed tightly against the mouth of the borehole.
