Finished product cooling bin provided with secondary feed port

The invention discloses a finished product cooling bin provided with a secondary feed port. The cooling bin comprises a cooling bin body and a cooling bin body fixed mount, wherein an upper supporting layer and a lower supporting layer are arranged inside the cooling bin body in sequence from top to bottom, the upper supporting layer is fixed, and the lower supporting layer is removable; a lower supporting layer fixed support is arranged at the lower part of the lower supporting layer; ventilation gaps are formed in the fixed joint of the lower supporting layer fixed support and the cooling bin body; cooling air enters the cooling bin from the ventilation gaps; a plurality of supporting strips which are arranged at intervals are respectively arranged on the upper supporting layer and the lower supporting layer; gaps in the upper supporting layer do not correspond to gaps in the lower supporting layer; the secondary feed port is formed in the lower part of the cooling bin body. Oversized materials or unqualified and unpackaged materials after cooling can quickly enter a classifying screen again through the secondary feed port for classification and packaging, so that the production efficiency is improved, and the using requirements of enterprises are met.
