DEVICE FOR MIXING DRY FORAGES AND ADDITIVES Russian patent published in 2017 - IPC A23N17/00 B01F3/18 B01F7/04 B01F7/08 

FIELD: agriculture.

SUBSTANCE: device for mixing dry feeds and dry additives consists of the hopper for dry forages in which unloading screw is installed, made in the form of a spiral of round cross-section; in the discharge area the unloading screw is made in the form of U-shaped blades of round cross section, made from a rod with the diameter of 4…10 mm and turned relative to the rotation axis at the angle α=5…15° in the course of the spiral turns in the hopper, wherein the mesh is located above the U-shaped blades of circular cross section, made in the form of plates with rectangular penetration holes with the width across the screw shaft of 15…30 mm and the length of 30…70 mm with jumpers of 2…4 mm; a multicomponent hopper-doser for dry additives is located in parallel with the hopper for dry forages, having blade drums with flat radial blades in the amount of 6…20 pieces and discharge openings in the form of cracks overlapping with adjusting dampers in two to seven sections on a common shaft; wherein the pre-mixing chamber is located under said hoppers, under which the main mixing chamber representing a cylinder, along the axis of which two sequentially located working bodies of active mixing are located on the drive shaft, wherein the first working body represents U-shaped blades of round cross section, in an amount from 4 to 10, fixed on the shaft and turned relative to the rotation axis at the angle β=5…15°, and the second working body, designed for mixing and unloading, which represents a double-flighted spiral-like conveyor, is also mounted on the shaft immediately after the first working body with U-shaped blades.

EFFECT: high quality of mixing forage components, ease of structure manufacturing, low energy consumption for obtaining the mixture.
