摘要:
A mining plough for plough systems for the exploiting of minerals in inclined formations. In order to provide a mining plough and a plough system, with which coal seams, in particular seams in steep formation can be exploited economically and with high operating safety, the mining plough includes a separable plough body having two plough body basic elements each being provided with a fixture for a separate traction means and with a guide means for moving the coal plough by means of at least two traction means and for guiding the coal plough on at least two mutually spaced guide mechanisms.

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.

The invention relates to a device for determining the cutting horizon of a mining winning system, having a movable conveyor which is composed of individual pan elements, and having at least one optical detection sensor which has a sensor head that is received in a sensor carrier and can be pressed with at least one pressure means against a coal/basement rock boundary layer. In order to improve the sensing and working reliability, over the length of the conveyor, a plurality of pan elements are configured as sensor pans which are provided with a protected recess which is open to the basement rock and in which the sensor carrier is arranged or can be arranged such that it can be disassembled together with the sensor head.

A mining plow with a plow basic body which can be guided on a conveyor and which has on an inclined bearing surface a pivoting bolt for the pivotable mounting of a cutter carrier for each plow travel direction Two cutter carriers are mounted pivotably on respective pivoting bolts by a pivot bearing such that each cutter carrier is guided on a pivoting surface oriented concentrically about the pivot axis of the associated pivoting bolt and formed below the bearing surface on the plow basic body. The pivot bearing of each cutter carrier includes an open-edged receptacle, each cutter carrier being located on the pivoting bolt parallel to the bearing surface in a pivoting mounting position.

A connection device for a plow installation, the device including a connection bracket having a basic body operable for attachment to a channel or guide section of the plow installation. A joint socket in the basic body includes a socket portion operable to receive a joint head of a boom cylinder. First and second legs are arranged in parallel and separated by a predetermined distance, with each leg including an inside portion and an outside portion. First and second supporting webs are located on the outside portions of the first and second legs, respectively. First and second bolt holes are located in the first and second legs, respectively, with a diameter of each bolt hole increasing from the inside portion of each leg to the outside portion. A joint bolt is located in the first and second bolt holes, and a clamping piece is located in each bolt hole.

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.

The invention relates to a drive station for an underground plough system, in particular a coal plough system, with a machine frame to which a plough box can be fastened, and with a wedge trough which is connected to the machine frame and is provided with a plough guide device, which has chain channels for a plough chain, and also a plough end stop on a runout section for a winning plough. In order to facilitate the repair of a winning plough, the plough end stop is formed on an attachment which can be dismantled, when the plough guide device is mounted, to produce a repair section in the longwall-gallery transition of the wedge trough. The invention also relates to a repair method in which the plough end stop is dismantled and the winning plough is moved into the repair section.

The invention relates to a sprocket for chain drives, with an axis of rotation and with two groups, arranged next to and offset with respect to one another on the circumference of the sprocket, of pockets for chain links passing the sprocket in an oblique position. Each pocket is delimited laterally by a side wall and an opposite wall and, in the circumferential direction, by webs. In order that a sprocket for chain links running in obliquely can be produced more simply and to provide a better distribution of forces, according to the invention the side wall and the opposite wall of a pocket form for the chain links bearing surfaces which run obliquely with respect to the axis of rotation and which extend as far as a bottom of the pockets.
