SEEDER FOR HERBS BAND SEEDING INTO SOD Russian patent published in 2010 - IPC A01C7/00 A01B49/06 A01B33/10 

FIELD: agriculture.

SUBSTANCE: seeder contains the following components, serially arranged on a frame: a milling section, seed guides, a seed box with seeding devices and compacting rollers. The milling section has a mechanism for sod treatment depth adjustment and is covered with a housing. The seed guides, seed box and compacting rollers are mounted in the housing rear part. The milling section working tools are represented by blades. The blades have a deflected wing part at an angle in the longitudinal-vertical plane of the trapezoid-shaped wing. The angle varies within the range of 0<α<α_max, where α angle of the deflected wing part; α_max - maximum magnitude of the angle of the deflected wing part. Angle α_max magnitude is calculated from the expression: ,

where Δb - allowable deviation of the width of the band being treated; h - maximum treatment depth.

EFFECT: design solution enables sowing process energy intensity reduction as well as improvement of soil compaction conditions in the bands after herbs seeding in case the seeding apparatus driving is nor accurate enough.
