FIELD: agricultural engineering, in particular, general-purpose equipment for precision and single-seed drilling.
SUBSTANCE: drill has seed hopper, seeding guides and rotating drum. Drum cavity is divided into central chamber and peripheral chambers. Each of peripheral chambers has funnel and is coupled to seeding chamber. Said chamber is equipped with device for regulating single-seed and timely feeding of seeds and is connected to seeding guide. Seed guides are rigidly mounted on drum outer surface and equipped with curved end oriented in the course of advancement of drum. Hopper is communicated with drum cavity through its hollow shaft provided with openings. Drum has wedge-shaped surface. Lower part of curved seeding guide has sharpened tip of hard alloys and upper part is made sheared. Seed guide curvature radius is commensurable with inner diameter.
EFFECT: increased precision of drilling without disturbing of natural herbage and tomentum litter under compound soil relief conditions.
