MACHINE FOR FERTILIZER MIXING AND BIOMODIFICATION OF GRANULAR SOLID MINERAL FERTILIZERS Russian patent published in 2023 - IPC A01C17/00 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering, in particular to machines for mixing fertilizer and biomodification of granular solid mineral fertilizers. The machine contains a frame. A loading auger-feeder and an unloading auger are installed on the frame in a common housing, interconnected by a common shaft. On the body of the augers, with a gap for its free rotation, a drum with a rotation drive for mixing fertilizers is planted, having in its end parts, in the fertilizer mixture unloading area, unloading blades. A biomodifier supply dispenser with a receiving hopper and a dusting device is embedded in the mixing chamber. On the inner wall of the drum, mounted on paired roller bearings, the blades of direct and reverse unloading are fixed. In the upper part of the auger housing, a straight slide and a reverse slide associated with it are fixed, having an angle of inclination of the surfaces to the horizon of at least 45°, and a slope of 1-3° together with the housing to the side. unloading the fertilizer mixture from the drum. To supply components from the feed screw to the drum blades, a component loading chute is installed.

EFFECT: use of the machine will improve the quality, uniformity of mixing in the given dosed ratios of granules of solid mineral fertilizers and special biological preparations.
