COULTER SEEDER UNIT FOR PRECISE DEEP SOWING OF VEGETABLE, TILLED, FORESTRY AND MELON CROPS Russian patent published in 2018 - IPC A01C7/20 A01C5/06 

FIELD: agriculture; engineering industry.

SUBSTANCE: invention relates to the field of agricultural engineering, in particular to machines for precise deep sowing of tilled, vegetable and melon crops. Coulter seeder unit for the precise deep sowing of seeds contains beam (6), mounted on parallelogram hinge (4). In the front part, disc knife (5) in the form of a flat ring with flanges in the form of hollow cylinders is fixed to beam (6) on an inclined height-adjustable stand. Behind disc knife (5) on height-adjustable stand (8), a furrow-forming device in the form of a wedge is fixed, the leading edge of which is parabolic and has a sharpening. Behind the furrow-forming device on inclined spring-loaded stand (12) is seed-retainer (11) made in the form of two truncated cones joined oppositely by large bases to form a wedge-shaped roller. At the junction of the large bases of the cones, a seed groove is provided, which is interfaced with drill tube (10) of sowing apparatus (7). Seed-retainer (11) is made of elastically elastic material. Behind the seed-retainer (11) on beam (6), with the help of an inclined spring-loaded stand, there are harvesters (13), behind them seed harrow (16) is mounted.

EFFECT: such a constructive solution ensures an increase in field germination, the formation of rectilinear shoots, the provision of accelerated growth and development of plants, an increase in yield.
