Patent ID: 7980803

Claim:
A system for the delivery of bulk material, the system comprising: a discharge base in which discharge openings are formed; and a cover plate which is arranged on the outflow side of the discharge base at a non-zero distance (h) from the same, with the cover plate having openings which are arranged essentially in the same pattern as the discharge openings of the discharge base, wherein: the cover plate and the discharge base are movable relative to each other between an opened condition in which the discharge openings of the discharge base and the openings of the cover plate overlap each other at least partially, preferably being congruent, and a closed condition in which the discharge openings of the discharge base exhibit such an axial offset(s) from the openings of the cover plate that no overlap is produced; the discharge base has recesses which preferably are shaped essentially conically, with a discharge opening being formed in each of the recesses; and the distance (h) between the discharge base and the cover plate as well as a centre distance and a diameter of the openings of the cover plate are chosen such that a base diameter of heaps of bulk material forming on the cover plate in the closed condition of the bulk material delivery system is smaller than the smallest edge distance between adjacent openings in the cover plate.
