SOCK FOR SOWING SEEDS AND FERTILIZERS Russian patent published in 2018 - IPC A01C7/20 A01C5/08 

FIELD: agriculture; engineering industry.

SUBSTANCE: invention relates to agricultural engineering, in particular to seed shoes for underground widespread seeding of crops and fertilization. Sock for seeding and fertilizing includes stand (1) with an upper bracket (9), burster point (2), fertilizer hose (3), a seeder (4) with a spring element (8). On the upper bracket (9) of stand (1) limiter (11) of spring element (8) is fixed, limiter (10) of seeder (4) and electromagnet (12), which transmits periodic electromagnetic signals given depending on the structure of soil, coming from controlled device located in the cab of tractor. Seeder (4) is fixed by means of axis (5) with a bracket (6) of seeder (4), which is connected to the lower bracket (9) of stand (1) by bolt joint for returning seeder (4) to starting position after the force on the side of electromagnet (12) is ceased.

EFFECT: provides more even distribution of seeds in depth, increased yields of grain crops and reduced traction resistance in implementation of controlled process of soil compaction.
