ABSTRACT:
A reciprocating discharger for discharging solid materials from the underside of a pile, has at least one reciprocating stoker rod with a piston arm at one end 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 arm does not extend outside the frame, which answers that the solid materials in the pile do not contact the piston arm.
