Description

Schrämmaschine mit sich drehender und zugleich in Achsenrichtung stoßweise vor- und rückwärts bewegter Schrämstange Gegenstand der Erfindung ist eine Schrämmaschine mit sich drehender und zugleich in Achsenrichtung stoßweise vor- und rückwärts bewegter Schrärnstange. Die Erfindung besteht darin, daß auf der Schrämstange Schrämpicken vorgesehen sind, die bei der Rückwärtsbewegung der Schrämstange die stehengebliebenen Drallrippen der Vorwärtsbewegung wegstoßen. Zu diesem Zweck sind die auf der Schrämstange angebrachten Schrämpicken doppelschneidig ausgebildet.Cutting machine with rotating and at the same time intermittently in axial direction cutting bar moving forward and backward The subject of the invention is a cutting machine with rotating and at the same time jerky moving forwards and backwards in axial direction Tie rod. The invention consists in that cutting picks on the cutting rod are provided, the stopped when the cutting rod is moved backwards Push away the twisting ribs of the forward movement. For this purpose they are on the cutting bar The attached cutting bits are double-edged.

In der Zeichnung ist in Abb. i bis 3 der Erfindungsgegenstand dargestellt.In the drawing, the subject of the invention is shown in Fig. I to 3.

Der Schrämstange a. wird mittels der Antriebsmaschine b mit ähnlicher Wirkungsweise der Gesteinsbohrschlaghämmer eine stoßende Vor- und Rückwärtsbewegung und außerdem, bei der Vorwärtsbewegung, eine Verdrehung um 1-j" Gang - 30° erteilt, so daß durch die doppelschneidig ausgebildeten Schrämpicken mit der vorderen Schneide d Drallnuten in das Kohlenflöz gestoßen werden. Bei der stoßenden Rückwärtsbewegung der Schrämstaube, die geradlinig erfolgt, werden die bei der Vorwärtsbewegung stehengebliebenen Drallrippen durch die hintere Schneide c weggestoßen.The cutting rod a. is by means of the prime mover b with similar The rock drill hammers work a thrusting forward and backward movement and in addition, when moving forward, a rotation of 1-j "gear - 30 ° is given, so that the double-edged cutting picks with the front cutting edge d swirl grooves are made in the coal seam. During the pushing backward movement the cutting pigeon, which takes place in a straight line, become those that have stopped while moving forward Twist ribs pushed away by the rear cutting edge c.
