FEED MIXER-DISPENSER Russian patent published in 2007 - IPC A01K5/00 A01F29/00 

FIELD: agricultural engineering, in particular, feed production.

SUBSTANCE: feed mixer-dispenser has hopper with discharge window provided through side wall, mixing screw positioned in spaced apart relation along hopper and connected with drive shaft. Mixing screw has spiral coils for displacement of material toward discharge window, said coils being equipped with plated knives for grinding of stalks. Plated knives are fixed on coils along their outer edge. Driven dispensing screws are positioned above cantilevered mixing screw which is kinematically connected with drive shaft for angular offset of natural axis of rotation of screw relative to axis of drive shaft for increasing said space. Free end of screw cooperates by means of supporting roller mounted thereon with screw offset restricting device formed as closed-contour supporting surface for roller, said surface being positioned on rear wall of hopper.

EFFECT: elimination of screw wedging, increased homogeneity of fraction composition of feed mixture, and reduced consumption of power for process.
