LOOSE MATERIAL STORAGE AND UNLOAD DEVICE Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: drives of conveyers 2 and 3 are energized, the belt and the chain of the conveyers move in opposite directions under the bottom of bunker 1. The bottom is made from plates 1 hinged to axles 5 and supported by rollers 6 mounted on chains 7 along bunker 1. When chain 7 moves rollers 6 fastened to it disengage with the plates 4 supported by them. The plates effected by the material rotate around axles 5 forming a hole in the bunker bottom through which the loose material is poured out of the device. When chain 7 of conveyer 3 is moved further or reversed rollers 6 turn plates 4 and return them into the initial position overlapping the bunker bottom. EFFECT: reduced material damage. 4 dwg
