Die Erfindung bezieht sich auf den bekannten Preßluftbohrer, der mittels einfacher Ventilumstellung entweder als Gesteinsbohrhammer mit ständig gedrehtem Meißel oder als Kohlendrehbohrmaschine verwendet werden kann. Im besonderen besteht die Erfindung in einer Verbesserung derjenigen Art solcher Bohrmaschinen, bei der der Schlagkolben innerhalb eines umlaufenden Zylinders spielt. Das Getriebe besteht im wesentlichen aus der Turbine G, die auf der Achse E drehbar in Kugellagern IV gelagert ist. Das Antriebsrad y, das mit der Turbine G verbunden ist, steht mit dem Zahnrad D- des Vorgeleges C in Eingriff, während das Zahnrad/7 des Vorgeleges C mit dem auf der Achse E feststehenden Zahnrad X in Verbindung steht. Durch diese Anordnung des Turbinengetriebes wird erreicht, daß die Kraftentwicklung direkt im Augenblick entfaltet wird, wo die Luft in das Einlaßventil eintritt. Dies wird dadurch erreicht, daß sich die Turbine, welche unabhängig von der Arbeitsachse, auf der sie gelagert ist, dreht.The invention relates to the known compressed air drill, which can be used either as a rock drill with constantly rotating chisel or as a coal drill by means of a simple valve changeover. In particular, the invention consists in an improvement of that type of such drilling machine in which the percussion piston plays within a rotating cylinder. The transmission consists essentially of the turbine G, which is rotatably mounted on the axis E in ball bearings IV. The drive wheel y, which is connected to the turbine G, is in engagement with the gear wheel D- of the counter gear C , while the gear wheel / 7 of the counter gear C is connected to the gear wheel X fixed on the axis E. This arrangement of the turbine gear ensures that the force is developed directly at the moment when the air enters the inlet valve. This is achieved in that the turbine, which rotates independently of the working axis on which it is mounted, rotates. Dadurch ist ruhiger Gang, sofortiges Arbeiten, konstante Leistungsfähigkeit und die im Bergbau handliche Länge der Maschine bedingt. This results in a smooth walk, immediate work, constant performance and the im Mining manageable length of the machine conditional. In der Zeichnung ist der Erfindungsgegenstand dargestellt.The subject of the invention is shown in the drawing. Gebrauch der Maschine zum Bohren von Kohle.Using the machine to drill coal. Ventil B wird geschlossen, A geöffnet. Die Luft tritt bei A ein und drückt vor die in der Turbine G lose sitzenden Lamellen H; diese werden, weil sie sich im exzentrischen Gehäuse befinden, bei der Drehung ein- und herausgeworfen. Die Turbine G sitzt auf der in Kugellagern IV gelagerten Achse E. Damit die Luft an den Seiten der Turbine nicht entweichen kann, befinden sich dort die Scheiben«. Mit der Turbine verbunden ist das Antriebsrad);. Dieses greift in das darüber lagernde Zahnrad D des Vorgeleges c. Dieses ist in Kugellagern I und II auf der feststehenden Achse K gelagert. Das Zahnrad F des Vorgeleges c greift in das auf der Achse E festsitzende Zahnrad X und bringt die Achse E damit auch den inneren Zylinder^ und den Bohrer Γ in drehende Bewegung. Die verbrauchte Luft entweicht durch/.Valve B is closed, A is opened. The air enters at A and presses in front of the lamellae H, which are loosely seated in the turbine G; because they are located in the eccentric housing, they are thrown in and out during rotation. The turbine G sits on the axis E, which is mounted in ball bearings IV. The disks are located there so that the air cannot escape on the sides of the turbine. Connected to the turbine is the drive wheel). This engages in the overlying gear D of the countershaft c. This is mounted on the fixed axis K in ball bearings I and II. The gear F of the countershaft c engages with the gear X , which is fixed on the axis E , and brings the axis E with it also the inner cylinder ^ and the drill Γ in rotating motion. The used air escapes through /. Gebrauch der Maschine zum Bohren von Gestein.Use of the machine for Drilling rock. VentilS und A werden geöffnet. Die Luft aus A bringt die Turbine in drehende Bewegung, wie vorher beschrieben, und entweicht aus /. Die Luft, die aus Ventil B strömt, strömt in die hohle Kammer α des Innen-Zylinders q2 und tritt dort in die Kanäle M-das Innenzylinders. Durch die drehende Bewegung kommt die Luft abwechselnd einmal aus ti, durch M, in die Kanäle des Außenzylinders N und q, die die Luft einmal durch N-O vor - den Kolben P, ein andermal durch die Kanäle q-R hinter den Kolben ρ gelangen lassen. Der Kolben P schlägt vor den beweglichen Luftverdicihtungsstopfens; dieser gibt den Schlag an den Bohrer Γ ab. Um ein-Herausfallen des Bohrers zu verhüten, ist dort ein Bohrhaltestück U angeschraubt. An diesem befindet sich ein gabelförmiges Fangeisen w, welches den Bohrer nicht herausschlüpfen läßt.Valve S and A are opened. The air from A causes the turbine to rotate, as previously described, and escapes from /. The air that flows out of valve B flows into the hollow chamber α of the inner cylinder q 2 and there enters the channels M- the inner cylinder. As a result of the rotating movement, the air comes alternately once from ti, through M, into the channels of the outer cylinder N and q, which allow the air to pass through NO in front of the piston P, and another time through the channels qR behind the piston ρ . The piston P strikes the movable Luftverdicihtungsstopfens; this transfers the blow to the drill Γ. In order to prevent the drill from falling out, a drill holding piece U is screwed on there. At this there is a fork-shaped catch iron w, which does not allow the drill to slip out.
