Abstract

The feed system for a coal getting combine works with a face conveyor. It comprises: a traction device located on the combine and having a cylinder-shaped sprocket on the side surface of which a circular spherical-shaped recess is provided, slots being made on both inner sides of the spherical recess, the slots having an involute-spherical surface. Arranged lengthwise of the conveyor is a longitudinally traversable guide bar secured at the ends of the conveyor and composed of a number of separate tubular sections articulated together and provided with open-end holes arranged square with the longitudinal axis of the holes.
