INSTALLATION FOR PREPARATION OF FEEDSTUFFS Russian patent published in 2016 - IPC A23N17/00 

FIELD: agriculture.

SUBSTANCE: invention relates to devices for mixing feedstuffs. Device comprises drum, loading and unloading devices, fixed on the platform. Drum is rigidly fixed on the platform with vibrator, mounted horizontally under platform, and 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 of spiral drum. Drum is equipped with screw grooves arranged inside at an angle to its spiral axis, in the form of pockets of wavy shape with centers of curvature located alternately inside and outside hollow cross section of the tunnel. Drum is assembled of sections in the form rings identical in shape and size, coiled from identical diamond shaped strips, on which there are trapezes, lateral sides of which are located on lateral sides of diamond shaped strip, and the upper and lower bases of trapezes are at an acute angle to the axis of symmetry of the diamond shaped strip 0₃-0₃ and are flexure lines, located from each other at distances equal to length of pockets of wavy shape along inner surface of hollow spiral tunnel. Sections in form of rings are interconnected by lateral sides of trapezium.

EFFECT: invention usage allows to expand operating performances of device for mixing feedstuffs.
