MINERAL FERTILIZER SPREADER Russian patent published in 2006 - IPC A01C15/00 

FIELD: agricultural engineering, in particular, equipment for application of granulated fertilizer during sowing process.

SUBSTANCE: spreader has flow former and flow divider disposed under flow former. Flow former of spreader is made in the form of branch pipe for connection to flexible fertilizer guide of drill and is attached to lever, which is embracing bracket shank extending in parallel with branch pipe for attachment on drill shank, said lever being positioned for rotation and fixation. Flow divider is made in the form of double-faced wedge consisting of two plates. Pinion is provided on front end of one plate defining face and on rear end of other plate defining face. Pinions are positioned in bushings fixed on bracket. Pinion axes are aligned relative to apex of double-faced wedge, and axis of branch pipe intersects at a right angle apex of double-faced wedge. Panel fixed on bracket is provided with arcuate slots wherein fingers provided on plates are inserted. Nuts threaded onto said fingers rest upon panel, which on its turn rests upon finger shoulders. Angular divisions are applied along arcuate slots, and arrows mating said angular divisions are positioned on fingers. Parameters of spreading fertilizer granules are designated by setting angle α of inclination of faces relative to base of double-faced wedge through rotation of plates on pinions and fixation thereof by means of nuts. Fertilizer granules may be spread only from one side of double-faced wedge owing to locating branch pipe in asymmetric manner relative to apex of double-faced wedge by rotating and fixing of lever on shank.

EFFECT: increased efficiency by adjusting local distribution of granulated fertilizer in the region of seed bed.
