FIELD: mining, chemical, coal construction, metallurgy and other industries. ^ SUBSTANCE: proposed hopper contains housing, material agitator installed in housing and agitator holder mounted on frame. Upper part of housing is made rectangular. Working member-agitator is made in form of flexible resilient elements, their planes pointed to middle of hopper are furnished with horizontal staggered rods. Planes of resilient elements pointed to walls of hopper are furnished with vibrators and are loaded by springs. Vibrators are secured on working member symmetrically relative to axes of symmetry of hopper at definite pitch, being fitted in holes in hopper walls. Cups with springs are secured in staggered order on outer planes of walls of hopper housing. Screw plugs are secured at end of springs. Screw plugs rest on plane of working member and bottom of cup, respectively. Working member is secured in rectangular frame only in upper part of hopper. ^ EFFECT: intensification of process of breaking of material frozen on walls of hopper and material bridge. ^ 3 dwg |
