BED FORMER-DRILL Russian patent published in 2006 - IPC A01B49/06 A01C7/00 

FIELD: agricultural engineering, in particular, equipment for simultaneously forming beds and seed sowing.

SUBSTANCE: bed former-drill has furrow formers, cutter with housing, fertilizer seeding units, and drill with seed guides. Shield is pivotally attached to lower rear part of cutter housing. Shares formed as coverers are rigidly attached to end of lower horizontal part of shield. Section of coverers in horizontal plane is formed parabolic for 2/3 the length from nose part and rectangular for 1/3 the length. L-shaped plates diverging at an acute angle to longitudinal axis are fixed to rear walls of coverers. Upper parts of plates are rigidly connected with horizontal ends to shield and to one side of supporting flare. Flare is made in the form of truncated cone rigidly mounted in vertical position above L-shaped plates and rear edge of shield in axially aligned relationship to central longitudinal axis of coverer. L-shaped shanks are mounted along axis of symmetry to lower surfaces of ends of L-shaped plates. Inclined part of shield is formed along radius of junction between cutter housing and horizontal part of shield equipped with vertical hydraulic pressure mechanism.

EFFECT: improved quality of preparing of soil for sowing, uniform distribution of seeds in depth layer and stable compaction of soil through the entire width of bed.
