摘要： A retraction mechanism for drawing a plough drive chain into a chain channel of a coal plough guide built onto the side of a scraper chain conveyor comprises a retraction slide which can be drawn through the chain channel and guided. The plough chain is connected to the slide which, via a chain section and a chain claw can be connected to an external traction drive, preferably to the scraper chain assembly of the scraper chain conveyor, so that the mechanism can draw the plough drive chain through the chain channel. The traction chain incorporates an overload clutch which limits the traction force. The clutch has two complementary parts one of which has a detent ball pressed by a prestressed spring into a detent recess of the other clutch part, so that the clutch is closed. A releasable lock or fixing device secures the detent ball in its released position.

摘要： A mineral mining plough has a plough body provided with a carrier supporting roof-level cutters. The carrier is movable vertically with respect to the plough body so as to adjust the cutting level of the roof-level cutters. A worm mounted on the plough body and a toothed rack attached to the carrier constitute means for adjusting the vertical position of the carrier, the worm meshing with the toothed rack.

摘要： A method of winning material in a mineral mining working utilizes a mineral mining plough which is movable to and fro alongside a conveyor. The plough is provided with first cutter means arranged to win material lying in a first height range, and second cutter means arranged to win material lying in a second height range. The plough is driven on the downhill run with the cutter means so positioned that material is won to a greater depth over the first height range than over the second height range. The plough is then driven on the uphill run with the cutter means so positioned that material is won to a smaller depth over the first height range than over the second height range.
