mechanical engineering; materials handling facilities. SUBSTANCE: proposed invention relates to field of storage of loose materials, namely, to devices aimed at preventing formation of bridges in process of unloading of materials from hoppers of stationary plants and mobile vehicles. Hopper has bridge breakers made of flexible cantilever springs or plates. Some ends of bridge breakers are rigidly connected to side inner surfaces of hopper housing and are arranged at different levels with displacement, for instance, along rising screw line. Rods are installed vertically lengthwise the springs for intensification of bridge breaking. EFFECT: simplified design, no drives. 2 cl, 2 dwg
