Mining and conveying apparatus

An apparatus for mining a mineral seam and for conveying said minerals parallel to the mining face or breast comprising:

• a trough-like conveyor portion assembled from a plurality of pan-like members, each of said pan-like members of said conveyor portion comprising two guide pieces which are mirror images of each other and which form a channel attached to each other by a base plate, said guide pieces engaging and fitting with a bottom side centering strip in a plurality of comparatively short members distributed over the length of said pan-like member of said conveyor portion which are parts of two-legged bent plates extending beyond said guide pieces and are clamped releasably with top side clamping strips between said bent plates and a plurality of clamping plates screwable to said bent plates, the ends of a plurality of said clamping plates on the breast wall end of said bent plate overlapping and being only screwable to said bent plate in a center longitudinal section, said clamping plate on the excavated-tunnel side having approximately the length of said pan-like member and being provided with a round bead on a breast wall side longitudinal edge;
• a basin-like digging portion pivotally attached substantially vertically to the upper edge of said conveyor portion on the breast wall side of said apparatus, each of the trough parts of said digging portion extending from an unequal-legged bent basin-like plate, a guide provided on the upper longitudinal edge of said basin-like plate and another guide piece identical with said guide piece of said conveyor portion attached to the lower longitudinal edge of said basin-like plate;
• a substantially circular cross section strip attached to the vertex of both legs of said basin-like plate, which is
• clamped between said bent plate on said breast wall side and said clamping plates screwed thereon so as to be pivotable;
• a plurality of coupling members and crosspieces with mounting recesses fastened in the vicinity of a plurality of screws of said clamping plates under said bent plates;
• a substantially vertical longitudinal bridge plate supporting itself with a lower longitudinal edge on said bent plate on the excavated-tunnel side attached to the longitudinal edge of said clamping plate on said excavated-tunnel side, at least one spacing plate being attached beneath said clamping plate on said excavated-tunnel side;
• coupling housings for a plurality of bridge-like connecting elements insertable from above attached to enlargements having hammerhead-like ends to the ends of one of said pan-like members, the surfaces facing each other of said hammerhead-like emlargements being convex in a substantially vertical plane and being fit in suitably formed concave recesses in said coupling housings which are provided with a plurality of top and bottom side projections, a plurality of convex curved noses being provided on the facing sides of said coupling housings attached to one end of one of said pan-like members while said coupling housing located on the other end has a plurality of concave recesses fitting said noses in said facing surfaces;
• and
• a chain conveyor guided positively in said conveyor portion and in said digging portion incorporating a plurality of digging tools and carrier members.
