OPENER FOR SUBSOIL BROADCAST SEEDING OF CROP SEEDS

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to agricultural machinery industry. The opener for subsoil broadcast seeding of crop seeds comprises a hoe blade and a drill tube attached to the rack. A lower part of a spinning wheel is attached to the latter by means of a bolt. A seed deflector is rigidly connected to the lower part of a spinning wheel. The seed deflector is made in the form of a hollow hemisphere with its apex facing downwards, and is mounted under the drill tube coaxially to the latter. In the seed deflector housing there is a rectangular window at the side directed counter the opener direction of travel along an arc of circumference of the hemisphere base with a central angle within 90° to 180°. The lower window edge is parallel to the plane of the hemisphere base. The upper edge coincides with the lower edge of the drill tube.;EFFECT: invention enhances the uniformity of the subsoil distribution of seeds.;3 cl, 3 dwg
