DEVICE FOR FODDER PREPARATION Russian patent published in 2016 - IPC A23N17/00 

FIELD: agriculture.

SUBSTANCE: invention relates to devices for mixing feedstuffs. To expand technological capabilities and enabling fodder components transporting from loading to unloading at horizontal position of drum rotation axis, increasing efficiency in device, comprising drum, loading and unloading devices, fixed on platform, drum is made spiral from hollow tunnel with multi-turn crew surface along perimeter, coiled along spiral axis 0₁-0₁ around central rectilinear axis 0₂-0₂. Drum is equipped with screw grooves arranged inside and outside at an angle to hollow tunnel spiral axis 0₁-0₁ in form of pockets with three and more lateral sides. Drum is assembled of sections in form of identical in shape and size rings coiled from identical rhomb-shaped strips, on which there are trapezes, lateral sides of which are located on lateral sides of diamond shaped strip, and upper and lower bases of trapezium at acute angle to strip 0₃-0₃ axis of symmetry and are flexure lines located at distances from each other, equal to sides pockets length, wherein sections are interconnected with lateral sides of trapezium.

EFFECT: use of the invention enables higher quality of finished product.
