FIELD: packaging. ^ SUBSTANCE: hopper comprises a housing with loading and outlet pipes, bottom, side walls, a flexible container located inside. A part of the flexible container is mounted on the upper edges of the housing, and the upper and lower ends are connected respectively with the loading and outlet pipes and the lifting mechanism of the flexible container. The lower half of the flexible container is equipped with at least two elastic concentric rings placed coaxially to the symmetry axis of the discharge opening. The elastic rings are made with the ability to change the length of their circumference. ^ EFFECT: increased efficiency of unloading through self-regulation of curvature of the conical surface of the container during loading, without additional costs. ^ 5 dwg |
