Description

Bekanntlich ergeben sich für die maschinenmäßige Kohlengewinnung folgende Möglichkeiten: a) durch schneidende Wirkung, ib) durch schällende bzw. spanabhebende Wirkung, c) durch schlagende Wirkung. InAus#nutzung von (a) haben sieh,Sehrämmaschinen insbesondere in @mächtigen Flözen mit mehr oder weniger Erfolg @bewährt. Zu c) sind Abbaugeräte in allerlei Ausführungsarten bekannt. Zu b) hat man lediglich eine schälende, oder hobelnde-Wirkung durch Messer als Schneide erreicht, die beispielsweise am Kohlenhobel als Messerträger laufgebracht sind und-durch Hinundherziehen am Kohlenstoß Streifen won diesem ablösen.As is known, the following results for mechanical coal production Possibilities: a) by cutting action, ib) by peeling or cutting Effect, c) by striking effect. In # use of (a) have see, image machines proven especially in @ mighty seams with more or less success @. To c) are Dismantling devices known in all kinds of designs. For b) you only have a peeling, or planing effect achieved by knife as a cutting edge, for example on Coal planes are run as knife carriers and by pulling back and forth on the coal face Strip which peel off.

Die Erfindung hat sich zur Aufgabe gestellt, ei-ne Maschine zu kennzeichnen, idie näch #b) eine fräsende Wirkung ausübt, wobei die an Auslegern vertikal umlaufenden Frä.skörper im. Sinn von Walzenfräsern arbeiten und den Abbau;stoß hinterschneiden. Dies hat gegenüberbekannten Maschinen .den Vorteil, daß .die am Abbaustoß mit etlichen Sekundenmetern hin und her fahrende Fräsmaschine den Abbaustoß so hinterschneiäet, däB kein Zermahlendes Flözkörpers wie bei Verwendung dier Schrämmfasahinen usw. eintritt, sondern @die oft schon durdh den Gebirgsidruck angedrückten Lagen in größeren Stücken aus dem Stoß herausgerissen werden:, so idaß ein unbedeutender Anfall an Feinkohle entsteht. Durch -,die besondere Drehrichtung des Fräiskörpers werden die Lagen: herausrissen und nicht zermalmt.The invention has set itself the task of characterizing a machine, ihe next #b) has a milling effect, with the vertically rotating on booms Milling body in. Sense of milling cutters work and the removal; butt undercut. Compared to known machines, this has the advantage that those on the working face with several Milling machine moving back and forth for a few seconds undercut the excavation joint in such a way that that there is no grinding of the body of seams as when using the cutting pheasants etc. occurs, but @ the often already pressed by the mountain pressure in larger locations Pieces are torn out of the pile: so that an insignificant attack begins Fine coal is produced. By -, the special direction of rotation of the milling body will be the Layers: torn out and not crushed.

Die Zeichnung veranschaulicht ein Ausführungsbenspiel mach der Erfindung in Abb.,1, in Seitenansicht, in Abb. a im Grundriß und in Abb. 3 in Stirn@ansich t m einem Strebquers.ehnitt.The drawing illustrates an exemplary embodiment of the invention in Fig. 1, in side view, in Fig. a in plan and in Fig. 3 in front view t in a face cross cut.

Mit 1 ist der Kohlenstoß, mit z Idas Liegende und mit 3 das Hangende bezeichnet. Am Kopf q. .und am Ende 5 des Maschinenkörpers 6 mit lern Windenteil 7 ist je ein Fräser 8 angeordnet, der über eine Kette 9 angetrieben wird. (Wenn 8 und 9 arbeiten, sind 8' und 9' ausgerückt, und umgekehrt.) Die gewünschte Frästiefe wird durch Verstellen ,des Armes der Kette 9 (durch einten Schalthebel ro bewirkt. Umbei engenenFlözverhältnissen einenleichteren Transport der Fräsmaschine zu ermöglichen, können tdie Fräser 8 bzw. 8' und die Kette 9 b;zw. g' samt,den Armen abnehmbar eingerichtet werden.With 1 is the coal pile, with z Idas lying and with 3 the hanging wall designated. On the head q. . And at the end 5 of the machine body 6 with learning winch part 7 each has a milling cutter 8 which is driven via a chain 9. (If 8 and 9 are working, 8 'and 9' are disengaged, and vice versa.) The desired milling depth is effected by adjusting the arm of the chain 9 (by a shift lever ro. In order to enable easier transport of the milling machine in tight seam conditions, can tthe milling cutters 8 or 8 'and the chain 9 b; betw. g 'velvet, the arms are detachable will.

Die Drehrichtung _des Frälskörpers. ist so eingerichtet, daß er den Abbaustoß hinterschnendet und J:ie Langen des Flözkörpers ohne Zerreibung in Stücken aus -denn Stoß gerissen werden.The direction of rotation of the milling body. is set up so that he has the Mining face undercut and J: the length of the seam body without attrition in pieces from being torn from the shock.

Schnellfräser sind -im übrigen in der Lage, in steil stehenden Flözen, in denen ,das: Hangendie und, das Liegende zur seitlichen Begrenzung ödes Abbauraumes werden, bei der Hinundherfahrt den oberhalb lieggenden Abbaustoß zu hinbersdhnenden, wobei, -die Fräsmaschine in: ;geeigneter Weise !auf dem Versatz, der Zimmerung oder sonstigen Hilfseinrichtungen gefahren wird.In addition, high-speed milling cutters are able to work in steep seams, in those, that: the hanging and, the lying to the side delimitation of the desolate mining space are, when driving back and forth, the mining face lying above to overdone, where, -the milling machine in:; suitable way! on the offset, the carpentry or other auxiliary equipment is driven.

Der Schnellfräser wäre somit eine Universalmaschine für alle Flöze mit hartem oder weichem Abbaustoß und für alle Lagerungen und ist nicht mit irgendwelchen Sc ;rämeinriohtungen zu verwechseln.The high-speed cutter would therefore be a universal machine for all seams with hard or soft shock and for all bearings and is not with any Sc; rämeinriohtungen to be confused.
