Abstract: An elongated conveyor is adapted to extend along a mine face in an underground mine gallery. A mining machine, such as a coal planer or the like is reciprocably arranged in the space between the mine face and the conveyor and has a bottom plate sliding on the sole of the mine gallery and extending below and with an end portion thereof beyond the conveyor. An endless chain having an upper and a lower run is used to reciprocate the mining machine along the mine face. Chain guide means are connected to the side of the conveyor facing away from the mine face and comprise superimposed substantially cylindrical guide channels for respectively guiding the upper and the lower run of the endless chain. To improve the guiding of the mining machine, an elongated cylindrical guide member is provided fixedly connected to the end portion of the bottom plate thereof, and this elongated guide member is either slidably guided in the lower one of the superimposed guide channels and forms part of the lower run of the endless chain, or the elongated guide member is guided in a separate guide channel arranged between the conveyor and the chain guide means while the free end of the bottom plate is connected to the lower run of the chain.

Abstract: A double-chain conveyor is assembled of trough sections defining a bottom plate provided with lateral guiding walls for scraper elements and intermediate guides extending along the entire length of the conveyor and guidingly engaging lateral edges of flat chain elements arranged parallel to the bottom plate of the trough. The flat chain elements are provided with oblong holes extending in the direction of the chain and linking vertically directed ring-shaped chain elements with a play which permits shifting movements of all chain elements in the longitudinal direction. Intermediate drives are provided between superposed bottom plates of the trough and drive a chain wheel engaging the flat chain elements both in the upper and in the lower flight of the conveying chain.

Abstract: A crushing-machine housing accommodates a rotating crushing roller whose periphery travels in the same direction as the conveyor which feeds material through the crushing machine, the clearance between the crushing roller and such conveyor determining the maximum volumetric rate at which material can be fed through the machine. The crushing roller is of crankshaft-like configuration, having a crank pin carrying crushing implements located far from the crushing-roller rotation axis, to either side of the crank pin a respective crank web whose center of gravity is eccentric with respect to the crushing-roller rotation axis, and to either side of the crank webs a respective crank journal rotatably mounted on the machine housing. The crank webs of the crankshaft-like crushing roller carry crushing implements located on the side of the roller rotation axis diametrally opposite to the crank-pin tool-carrying part of the crushing roller. When the volumetric throughput of goods is to be changed, there is no need to stop the machine and raise its housing to create a greater clearance between the crushing roller and the conveyor, as in prior art.

Abstract: A scraper conveyor has a conveyor trough composed of at least two longitudinally adjacent trough sections having respective side walls and juxtaposed terminal faces. A pair of first connecting members is welded to the side walls of one of the sections and recessed longitudinally thereof from the terminal face of the one section. These first connecting members have convex first end faces directed towards the terminal face of the one section, and exposed outer surfaces. A pair of second connecting members is welded to the side walls of the other of the sections and each of these has an end portion projecting beyond the terminal face of the other section. The end portions have second end faces which are each formed with a concave recess in which one of the convex end faces is received, and also exposed outer surfaces. Substantially keyhole-shaped recesses are formed in the exposed outer surfaces and each of these has a narrow portion provided with an open end located at the respective end face, and with a wider portion spaced from the respective end face. Coupling elements are received in the keyhole-shaped recesses and each of these has two enlarged end sections received in the respective wider portions, and a narrower section received in the narrow portions of the cooperating recesses. With this construction the thus connected trough sections have limited freedom of relative angular displacement in vertical and in horizontal direction.
