STACK-SELF-FEEDER Russian patent published in 2004 - IPC

FIELD: agricultural engineering, in particular, equipment for storage and dispensing of feed to animals.

SUBSTANCE: stack-self-feeder has central support made in the form of parabolic cone narrowing in asymptotic path to column apex and approaching to base, dividing surface, and conical member. Dried hay is laid around central support onto parabolic cone to form stack. Dividing surface divides stack into two parts and hay is unobstructedly fed by gravity to base. Dividing surface prevents stack from spontaneous collapsing into cavities formed in stack by sheep. Stack of such construction enables destruction of arcs in central part to provide for stable automatic feeding of hay to animals.

EFFECT: increased efficiency, reduced hay losses and decreased costs for animal feeding.
