Abstract
A conveyor assembly extends longitudinally on the body portion of a mining machine. A forward end portion of the conveyor assembly is pivotally connected to the body portion so that a rearward end portion is movable through a vertical arc to facilitate discharge of mined material at a preselected height above the body portion. The rearward end portion is vertically raised and lowered by a piston cylinder assembly that is mounted on the body portion and is connected to the conveyor assembly. Actuation of the piston cylinder assembly positions the conveyor rearward end portion at an elevated position above the body portion. A stabilizing member is positioned between the conveyor assembly and the machine body portion with the upper end portion hingedly connected to the conveyor assembly and the lower end portion positioned for longitudinal movement between vertical sidewalls on the body portion. The lower end portion of the stabilizing member is restrained by the sidewalls from moving laterally on the body portion and thus serves to prevent the conveyor assembly from swaying laterally when positioned at a preselected height above the body portion.
