  • Patent number: 8733536
    Abstract: A transfer station in the face end region between a face conveyor and a gate conveyor in the region of a drive for the face conveyor, the gate conveyor being attached to the face conveyor such that it can be moved pivotably to a limited extent relative to the latter. The transfer station being provided with a receiving plate that is arranged on a subframe of the drive for the face conveyor, which receiving plate is provided with a bearing seat, in which a specific connection pan element of the gate conveyor is mounted such that it can be moved pivotably relative to the face conveyor or its drive about a pivot axis which is defined by the bearing seat. The construction has the particular advantage that the pivoting bearing is readily accessible and has to transmit only low forces which result substantially from the loading of the gate conveyor.

  • Patent number: 8714659
    Abstract: A bit arrangement for fastening to a plough-body element of a mining plough for underground mining, particularly of a coal plough for the excavation of steeply disposed coal seams, having a plurality of bit pockets for accommodating, preferably demountably, respectively one bit per bit pocket. In order thereby to create a bit arrangement and a mining plough that can be used advantageously for the excavation of steeply disposed mineral deposits and that render possible economic excavation of such mineral deposits, at least two bit pockets are locked in recesses on a front side of a bit strip, which is provided, on a back side, with at least one groove indentation for the positive engagement of a locking projection on the plough-body element and is detachably fastenable to the plough-body element by means of detachable fastening means.

  • Patent number: 8632134
    Abstract: A traction carriage for an underground mining plow, comprising a traction carriage body which can be inserted into a cavity in a plow body and which on the rear side of a guide recess has a front part whose ends pointing in the direction of travel form stop surfaces for interacting with counterstop surfaces in the cavity of the plow body. According to the invention, a damping device having a damping action in both directions of travel is integrated into the front part of the traction carriage. In order to provide a low-maintenance damping device which allows a more favorable transmission of force between the stop surface on the traction carriage and the counterstop surface on the plow body, the coupling piece can be moved relative to the stop surfaces counter to the restoring force of a damping system of the damping device that is arranged between the stop surfaces.
