A coal combine

Patent:

Abstract

A design is presented for a coal combine, equipped with two drum operational units, on whose both ends of the upper surface of the body, two coal saws are mounted with the help of a lever system. These saws, found in an operational position, form a gap in the block of the coal block, which is not embraced by the drum operational unit. The coal block, found between the gap and the support, falls down onto the longwall scraper conveyor. The lever system of each coal saw is controlled by two hydraulic jacks. One of the jacks is mounted vertically on the facial wall of the body of the combine and is used for the hoisting for the required height of the horizontal arm of the lever, reinforced by one end in the hinge on the body of the combine. On the ''free'' end of that lever, a coal saw is mounted in a hinge-like fashion and which is connected by the hydraulic jack to the horizontal arm of the lever system. This hydraulic jack is used for the clamping of the coal saw to the face.
