Gegenstand der Erfindung bildet eine Vorrichtung zum .Ausspülen von Bohrkernen bei drehenden Ges.teiiibohrmaschinen während der Bohrarbeit. Dies ist dadurch ermöglicht, daß das Druckwasser von außen diirch die Bohrkrone in das Bohrrohr gelangt und den Bohrschmand durch das "Bohrrohr hinausdrückt, um Verklemmungen des Bohrers zu verhindern. Bei den bisherigen drehendenThe subject matter of the invention is a device for rinsing out drill cores rotating joint drilling machines during the Drilling work. This is made possible by the fact that the pressurized water from the outside diirch the The drill bit gets into the drill pipe and pushes the drill debris out through the drill pipe to prevent the drill from jamming impede. With the previous rotating
ίο Gesteinbohrmaschinen wurde das Druckwasser vom rückwärtigen Teil der Bohrmaschine in das Bohrrohr eingeleitet und wirkte dadurch dem Vorschub der Maschine entgegen, drängte den Bohrschmand zusammen, so daß leicht Verklemmungen .des Bohrrohres eintreten konnten. Bei vorliegender Erfindung ist der Lauf des Spülwassers ein natürlicher, indem dasselbe in der Richtung des Austritts des , Bohrschmands wirkt. Das Bohrrohrίο rock drilling machines was the pressurized water introduced into the drill pipe from the rear of the drill and acted as a result counter to the advance of the machine, the drilling waste pressed together so that jamming of the drill pipe could easily occur could. In the present invention, the flow of the rinse water is a natural, by acting in the direction of the exit of the drilling waste. The drill pipe
ao selbst muß hierbei innen völlig glatt und hinten ganz offen sein, damit der Bohrschmand ungehindert während des Bohrens austreten kann. Das Bohrrohr muß mit einer Vorrichtung versehen sein, welche dasselbe nach außen abdichtet, so daß das Druckwasser zwischen Bohrrohr und Felswand hindurch durch die Bohrkrone in das Innere des Bohrrohres treten muß. Eine Ausführungsform des Erfindungsgegenstandes ist in der Zeichnung dargestellt, und zwar zeigen: Fig. ι einen Schnitt durch den Druckwassereinleiter und dessen Bewegungsvorrichtung, .ao itself must be completely smooth on the inside and completely open at the back so that the drilling smudges can escape unhindered while drilling. The drill pipe must be provided with a device which does the same seals to the outside, so that the pressurized water between the drill pipe and rock wall through must pass through the drill bit into the interior of the drill pipe. One embodiment The subject of the invention is shown in the drawing, namely show: Fig. Ι a section through the pressurized water discharge and its movement device, .
Fig. 2 eine Seitenansicht desselben und einen Schnitt durch den rückwärtigen Teil der Bohrmaschine.Fig. 2 is a side view of the same and a section through the rear part the drill.
Auf dem Bohrrohr c sitzt ein Gehäuse b, welches zwei Abdichtungen gf, sowie in .bekannter Weise einen Einlaufsstutzen α besitzt. Die Abdichtung g sichert das durch den Rohrstutzen eintretende Druckwasser vor dem Auslaufen aus dem Gehäuse b, und die Abdichtung / wird derart fest an die FeIs- \vand gepreßt, daß sie das Einlaufen des Druckwassers ohne A^erlust in das Bohrrohr sichert. Die Bohrkrone i hat, wie üblich, einen größeren Durchmesser als das Bohrrohr und ist mit Rillen k versehen, durch die das Druckwasser in das Innere des Bohrrohres gelangen kann. Das Gehäuse b wird von einem Arm d getragen, der vermittels eines Gewindes durch die Mutter ρ in einem am Maschinengestell befestigten Rohr verschoben werden kann. Das Druckwasser gelangt durch den Schlauch / und Rohrstutzen a in das Gehäuse b, tritt zwischen der Dichtung/ ' und dem Bohrrohr in das Bohrloch und von hier durch die Rillen k der Bohrkrone i in das Innere des Bohrrohres c. Durch das Druckwasser wird der Bohrschmand bezw. der Kern m durch das Bohrrohr, das am rückwärtigen Teile völlig offen ist, hinausgedrückt, so daß das Bohren selbst ungehindert vonstatten gehen kann, ohne daß Verklemmungen des Bohrers eintreten können.A housing b is seated on the drill pipe c and has two seals gf and, in a known manner, an inlet nozzle α . The seal g secures the pressurized water entering through the pipe socket from leaking out of the housing b, and the seal / is pressed so tightly to the wall that it ensures that the pressurized water flows into the drill pipe without loss. As usual, the drill bit i has a larger diameter than the drill pipe and is provided with grooves k through which the pressurized water can get into the interior of the drill pipe. The housing b is carried by an arm d which can be moved by means of a thread through the nut ρ in a tube attached to the machine frame. The pressurized water passes through the hose / and pipe socket a into the housing b, enters the borehole between the seal / 'and the drill pipe and from here through the grooves k of the drill bit i into the interior of the drill pipe c. By the pressurized water, the drilling smut is respectively. the core m through the drill pipe, which is completely open at the rear, pushed out, so that the drilling itself can proceed unhindered without jamming of the drill can occur.
