Description

Gewinnungsgerät, insbesondere für Braunkohle o. dgl., mit doppelseitig neben dem Fördermittel angeordneten Schürfrädern oder -ketten . Es sind bereits Gewinnungsgeräte in Vorschlag gebracht worden, bei denen zwischen zwei Schürfrädern die Fördervorrichtung angebracht ist, die das gewonnene Haufwerk aufnimmt und weiterfördert.Extraction device, especially for lignite or the like, with double-sided Mining wheels or chains arranged next to the conveyor. There are already Extraction equipment has been proposed in which between two mining wheels the conveying device is attached, which picks up the recovered debris and conveys it further.

Hierbei hat es sich als nachteilig herausgestellt, daß nur jeweils die Außenseite des vorlaufenden Schürfrades arbeitet, so daß dadurch das Haufwerk seitlich .des Schrämwerkzeuges abfällt und nicht der Fördervorrichtung zugeführt wird.It has been found to be disadvantageous that only in each case the outside of the leading scraper works, so that thereby the debris laterally .des the cutting tool falls off and is not fed to the conveying device will.

Zweck der vorliegenden Erfindung ist, diesem Übelstand abzuhelfen, und dieses wird dadurch erreicht, daß man das vorlaufende Schrämrad leer laufen läßt, während das zweite Schürfrad in den Stoß eingreift. Hierdurch wird erreicht, daß die gewonnene Kohle unmittelbar der zwischen beiden Schürfrädern angeordneten Fördervorrichtung zugeführt wird.The purpose of the present invention is to remedy this drawback, and this is achieved by running the cutting wheel in front leaves while the second scraper engages in the pile. This achieves that the coal obtained is directly disposed between the two mining wheels Conveyor is supplied.

In der Zeichnung ist das Wesen der Erfindung beispielsweise veranschaulicht.In the drawing, the essence of the invention is illustrated for example.

Ein schwenkbarer und höhenverstellbarer Ausleger i trägt in bekannter Weise an der Stirn zwei Schürfräder 2 mit .dazwischen angeordneter Fördervorrichtung 3. Die Schürfräder 2 sitzen fest aufgekeilt auf einer gemeinsamen Achse 4, die m einer mit einer Kugelkalotte 6 versehenen Hohlwelle 5 gelagert ist. Die Hohlwelle 5, .die gleichzeitig als Triebwelle ausgebildet ist, weist einen Keil 7 auf, der in einer Längsnut 8 des Bundes g der Hohlwelle 5 eingreift, so daß die Achse 4 zwangläufig in Drehbewegung von der Hohlwelle 5 mitgenommen wird, andererseits aber ein Schwingen in der Kugelkalotte 6 .ermöglicht. An den Enden der Achse 4 -greift ein Gabelstück io an, dessen Ende i i mittels Spindel und Spindelmutter 12 in bekannter Weise seitlich verstellbar ist. Hierdurch wird ermöglicht, daß die rechte oder linke Schrämkette bzw. Schrämrad entsprechend vorgelegt oder zurückgezogen werden kann.A swiveling and height-adjustable boom i carries in known Way at the forehead two scraper wheels 2 with a conveyor device arranged in between 3. The digging wheels 2 are firmly wedged on a common axis 4, the m a hollow shaft 5 provided with a spherical cap 6 is mounted. The hollow shaft 5,. Which is designed as a drive shaft at the same time, has a wedge 7, the engages in a longitudinal groove 8 of the collar g of the hollow shaft 5, so that the axis 4 inevitably is entrained in rotary motion by the hollow shaft 5, but on the other hand an oscillation in the spherical cap 6. A fork piece engages at the ends of axle 4 io at, the end of which i i laterally by means of a spindle and spindle nut 12 in a known manner is adjustable. This enables the right or left cutting chain or Schrämrad can be presented or withdrawn accordingly.
