ABSTRACT:
A reciprocating discharger for discharging solid materials from the underside of a pile, has at least one reciprocating stoker rod with a piston at one end connected to a piston rod reciprocating in a stationary cylinder which is mounted on a thrust member frame. The frame has a width greater than the length of a piston stroke, so that the piston rod does not extend outside the frame, thus the solid materials in the pile do not contact the piston rod. A hydraulic system is provided for the cylinder with a hydraulic oil reservoir, an integral power unit with an electric motor directly coupled to a variable flow, reversible piston type pump connected in a closed loop hydraulic circuit with the cylinder, and an automatic reverse arrangement to reverse flow of hydraulic oil to the cylinder after each stroke.
