SMALL-SIZED COMBINED FEED PRODUCTION UNIT Russian patent published in 2000 - IPC

FIELD: agriculture. SUBSTANCE: combined feed production unit has sectioned hopper, dosing augers positioned in lower part of each section of hopper, grinding chamber, and vibratory mixer with stepped hemispherical mixing members. Vibratory mixer is disposed rearward of grinding chamber. Diameters of mixing members are increasing from base to pointed end of teeth in accordance with arithmetic progression law. Length of each step of mixing members is equal to respective value of ordinal number of member of this progression, and height of each subsequent step, beginning from the second, is increased by the same value equal to 1/2 of difference of arithmetic progression. Mixing members of each step are staggered relative to each subsequent row of mixing members. Such construction allows additional mixing of fodder mass to be accomplished due to creating alternatively directed spiral motions along the whole length of mixing members and along generatrices of hemispheres of each step in different directions. Unit of such construction may be employed for producing combined feed from local raw material in animal farms and complexes, in individual and collective farms. EFFECT: increased quality of produced feed by improved extent of homogeneity of obtained mixture, reduced power consumption and decreased fodder mixing process. 2 dwg
