Selbsttätig arbeitende Kohlenschrämmaschine Patentiert im Deutschen Reiche vom 20. Oktober 1926 abAutomatic coal cutting machine. Patented in the German Empire on October 20, 1926

Die Erfindung bezieht sich auf eine selbsttätig arbeitende Kohlenschrämmaschine mit Schneideisen, die in das Flöz konzentrische Ringnuten einschneiden. Die Maschine ist hierbei in an sich bekannter Weise mit einer Einrichtung versehen, die das stehengebliebene Gestein durch Keilwirkung herausbricht. The invention relates to an automatically working coal cutting machine Round dies that cut concentric ring grooves in the seam. The machine is here in a known manner provided with a device that the stopped Rock breaks out due to wedge effect.

Gemäß der Erfindung werden zum Herausbrechen des stehengebliebenen Gesteins' keilartig" wirkende drehbare Scheiben verwendet, die auf den die Schneideisen tragenden -Armen so gelagert sind, daß sie sich in die geschnittene Nut bei deren fortschreitender Vcrtiefung einschieben und dabei gegen die Wände der Xut einen zunehmenden Druck ausüben.According to the invention are to break out of the remaining rock 'wedge-like' used rotating disks acting on the arms carrying the dies are mounted so that they fit into the cut groove as it deepens push in, applying increasing pressure against the walls of the Xut exercise.

Bei der zweckmäßig zur Anwendung gelangenden Ausführungsform der Erfindung liegen die flach ausgebildeten Brechscheiben in der Bewegungsrichtung der bogenförmig gestalteten Schneideisen hinter letzteren und sind mit Bezug auf diese Schneideisen längs und seitlich einstellbar.In the embodiment of the invention which is expediently used the flat breaking disks in the direction of movement of the arcuate ones Dies behind the latter and are longitudinal and with respect to these dies laterally adjustable.

In den Zeichnungen sind Ausfülirungsformen der Erfindung beispielsweise dargestellt, und zwar istIn the drawings are embodiments of the invention is shown for example, namely

Fig. 3 veranschaulicht eine Abänderung, und3 illustrates a modification, and

Fig. 4 ist ein Schnitt nach der Linie 3S-38 der Fig. 3.FIG. 4 is a section on line 3S-38 of FIG. 3.

Beim dargestellten Ausführungsbeispiel besitzt die Schrämmaschine einen Rahmen, der obere und untere Schienen 1, 2 aufweist, von denen die unteren Schienen zwecks Verschiebung der Maschine in dem Bergwerk von j Rollen oder Rädern 3, 4 getragen werden. .1 An dem Stirnende der Maschine sitzen j zwei Schneidköpfe 10, 11, von denen jeder j eine Mehrzahl von Schneideisen' trägt, die in radialer Richtung in einem gewissen Abstand voneinander liegen. Die Schneidköpfe werden j in bekannter Weise durch Welle 13 in Umdrehung versetzt, die zu beiden Seiten des Rahmens parallel verlaufen und in geeigneten Lagern ruhen. Die Schneidköpfe 10,11 werden hierbei z\veckmäßig in entgegengesetzten Richtungen gedreht und bestehen vorzugsweise aus flachen Stangen, auf denen die Schneideisen 20, 21 sitzen, welche zweckmäßig mit gezahnten Kanten versehen sind. - Die Schneideisen 20, 21 weisen eine Krümmung auf, die ihrem radialen Abstand von der Mittelachse der Welle 13 entspricht: die Krümmung ist somit für die inuenliegenden Schneideisen schärfer, und die der äußeren Schneideisen flacht sich fortschreitend iivgrößerem Maße ab, so daß die Schneideisen in das Kohlenflöz in genau kreisförmigen Bahuen eindringen.
; Durch diese Schneideisen wird in demIn the embodiment shown, the cutting machine has a frame which has upper and lower rails 1, 2, of which the lower rails are supported by rollers or wheels 3, 4 for the purpose of moving the machine in the mine. .1 At the front end of the machine there are two cutting heads 10, 11, each of which carries a plurality of cutting dies, which are at a certain distance from one another in the radial direction. The cutting heads are set in rotation in a known manner by shaft 13 which run parallel on both sides of the frame and rest in suitable bearings. The cutting heads 10, 11 are rotated in opposite directions and preferably consist of flat rods on which the cutting dies 20, 21 sit, which are expediently provided with toothed edges. - The dies 20, 21 have a curvature which corresponds to their radial distance from the central axis of the shaft 13: the curvature is thus sharper for the internal dies, and that of the outer dies gradually flattens out to a greater extent, so that the dies in penetrate the coal seam in precisely circular paths.
; This die is used in the

Kohlenflöz eine Anzahl konzentrischer Eoh- ! lenringe hergestellt, die bei Erreichung einer , von den Schneid^verkzeugen hergestellten Tiefe abbrechen und auf den Boden des Stol-Coal seam a number of concentric ! lenrings are produced, which when one is reached, produced by the cutting tools Break off the depth and hit the bottom of the

Claims

They fall in front of the machine, from where they are brought up in a suitable manner, for example by a shovel 22, and then stirred backwards. - ".-." -

In order to facilitate the breaking out of remaining rock, according to the invention, rotatable breaking disks 26, 27 are provided which are fastened to the cutting head by means of integrated bearing blocks. These Lsgerb blocks are attached to the edge of the cutting head that is the rear edge with respect to the direction of rotation. The breaking disk 26 is rotatable and. is, as shown, essentially in alignment with the second cutting tool, calculated from the middle, on one side of the cutting head (FIG. 2). The disk 20 is straight with respect to the curvature of the adjacent cutting tool, and it can be given any desired inclination so that it exerts a self-directed pressure on the second concentric ring and thus strives to break this ring out. which is also arranged on the rear edge of the cutting head .. The disc 27 is at a greater distance from the cutting head and opposite the cutting tool in order to break off the outermost concentric ring of carbon The cutting head 11 is similarly equipped with breaker disks to enable the carbon rings that have been cut out to be broken off.

In the case of the A'üsführungsform shown in FIGS. 3 and 4, the break out of the remaining rock, crushing disc183 carried by arms 1S4, which protrude from a plate 1S5. The plate 185 is used to adjust it Slits ΐβό provided, while screw pins: 187 go through the mentioned slots and enter die head 188. By loosening the screws 1S7, the pane can be moved back and forth to the desired position.

If.that is desired. can die-disks 183 also on relatively long tenons be mounted, which are attached between the arms, with a plurality of spacing rings used .and attached in the desired manner on these pegs will. This enables a further adjustment of the breakers on their shafts with respect to the grooves whom they work together to break out the coal. . .
