DEVICE FOR SOWING GRAIN CROP SEEDS IN CONDITIONS OF INCREASED SOIL HUMIDITY BY DRILL AND CLOSE METHODS

摘要

FIELD: agriculture.;SUBSTANCE: presented device includes a seed duct and a housing, in which furrow-formers are fixed. The latter are made in the form of two cutting discs and installed parallel to the motion direction. The discs are equipped on both sides with furrow-forming patches made of a polymeric material and have the possibility of axial movement on a shaft with fixation in the set position for adjusting the width of the row spacings, depending on the method of sowing (drill, close).;EFFECT: uniform distribution of grain crop seeds through the feeding area due to adjusting the width of the row spacings; increasing the device operability due to reducing the sticking of soil and crop residues onto the working surfaces.;2 dwg
