摘要

This invention is a fortifying frame (1) having a discharge opening (11) aligned with the centre of the ceiling cap (5). The said discharge opening (11) has a pushing plate (27) moved by a pushing drum (28). That way the front side (5) and the rear side (20) of the ceiling cap constitute a closed space and in the discharge opening (11) area, there are ceiling boards (36, 37) mounted in parallel to the discharge opening and laterally, what creates an optimal situation in the discharge opening (11) area for broken coals, when an appropriate support security is provided. That way, it is possible to draw coal free from broken coal particles and transfer it directly to the conveyor (9) through a slider shaped door (29) added to the discharge opening (11).
