SOWING SECTION Russian patent published in 2022 - IPC A01C7/20 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering, in particular to the sowing section for direct sowing of agricultural crops. The sowing section contains a parallelogram suspension of the tyne coulter with a chisel and a seed and fertilizer tube, a support-rolling wheel with a leg for attaching it to the coulter and a regulator of its position. The upper thrust of the parallelogram suspension is made in the form of a spring-reciprocating mechanism with the possibility of lifting the coulter when the latter comes into contact with an obstacle and returning to its original position after overcoming the obstacle. The chisel is mounted on the coulter pivotally with the possibility of turning forward relative to the hinge when lowering the sowing section to the soil surface when the unit is stopped.

EFFECT: invention provides for the automatic return of the sowing section rack to its original position after contact with an obstacle and the exclusion of clogging of the seed and fertilizer pipeline and the back space of the furrow forming wheel when lowering the sowing section to the soil surface when the unit is stopped.
