Description

Die vorliegende Erfindung bezieht sich auf einen Stollenbagger mit höhen- und seitenbeweglichem Bandausleger, bei dem vor dem Band ein Löffel mit aus der Schneide herausragenden Stößeln vorgeschaltet ist.The present invention relates to a tunnel excavator with vertically and laterally movable Ribbon boom with a spoon protruding from the cutting edge in front of the ribbon Ram is connected upstream.

Bei Gewinnung besonders harter Kohle hat es sich herausgestellt, daß die Leistung des Stollenbaggers in besonders günstiger Weise dadurch gesteigert wird, daß der Stößelkopf beiderseitig mit einer Schrämkette ausgerüstet ist. Durch die Schrämketten werden zunächst zwei Schlitze geschrämt, wonach dann die Schrämketten umgelegt bzw. zurückgezogen werden. Die dann zwischen den Schlitzen anstehende Kohle wird durch den Stößelkopf sehr leicht gewonnen.When extracting particularly hard coal, it has been found that the performance of the Tunnel excavator is increased in a particularly favorable manner that the ram head Is equipped with a cutting chain on both sides. By the cutting chains are initially Two slots are cut, after which the cutting chains are turned over or withdrawn will. The coal then pending between the slots is through the Ram head obtained very easily.

In der Zeichnung ist das Wesen der Erfindung beispielsweise veranschaulicht, und zwar zeigenIn the drawing, the essence of the invention is illustrated for example, namely demonstrate

Auf den Raupenketten 1 ist ein Oberteil 3 um einen senkrechten Zapfen 2 schwenkbar angeordnet. Der Oberteil 3 trägt einen Bandausleger 5, der um die Achse 4 heb- und senkbar ist. Der Ausleger 5 weist am vorderen Ende einen Löffel 7 auf, mit aus der Schneide herausragenden Stoßzähnen 8, die in beliebiger Weise betätigt werden können. Außerdem sind zwei Schrämketten 17, die entweder um eine Achse 6 umklappbar oder in einer Schlittenführung einziehbar angeordnet sind. Zweckmäßig erhalten die Schrämketten ihren Antrieb durch die Förderbandachse 6.On the caterpillars 1, an upper part 3 can be pivoted about a vertical pin 2 arranged. The upper part 3 carries a band boom 5 which can be raised and lowered about the axis 4 is. The boom 5 has a spoon 7 at the front end, with the cutting edge protruding tusks 8, which can be operated in any way. aside from that are two inclined chains 17, which can either be folded around an axis 6 or in one Slide guide are arranged retractable. Appropriately, the cutting chains get theirs Drive by the conveyor belt axis 6.

Der Oberteil 2 ist über der Drehscheibe in einer Schlittenführung 18 in der Längsrichtung verfahrbar. Der Antrieb des Fahrwerkes erfolgt durch eine Spindel 19 und eine Handkurbel 20.The upper part 2 is above the turntable in a slide guide 18 in the longitudinal direction movable. The chassis is driven by a spindle 19 and a Hand crank 20.
