HOPPER FOR COARSE-CRUSHED MATERIAL Russian patent published in 2011 - IPC B65D88/26 

FIELD: transport, package.

SUBSTANCE: proposed hopper comprises inclined walls 1, 2 and outlet 3 arranged at hopper bottom to discharge material from the hopper. Said inclined walls can turn inside the hopper by parts 5, 6 with their upper edges pivoted to hopper fixed parts. Inclined wall outer sides are articulated with rods 9, 10 of power cylinders 11, 12. Housings of power cylinders 11, 12 are hinged to aforesaid fixed parts of the hopper, while rods 9, 10 are spring-loaded to turning parts. Turning parts 5, 6 on hopper inclined walls 1, 2 are arranged on opposite walls of the hopper in symmetry about each other, while those at hopper lower part are arranged shifted in height that allows gravity loading of lumps from one turning part of the wall onto another. Lower edges of turning part of the walls rest, in initial position, on inner surfaces of hopper wall fixed parts.

EFFECT: longer life of hopper and unloader structural parts in irregular feed of coarse-crushed material into hopper.
