SOIL TILLAGE AND SOWING UNIT Russian patent published in 2017 - IPC A01B49/06 A01B61/04 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine building, particularly, to combined units and machines for soil tillage and planting. Unit for tillage and planting has located on frame (1) ripper rotor (2) with drive teeth (3) and tillage rotor (4) with discs, on which from both sides L-shaped blades are installed, connected with ripper rotor (4) by accelerating transmission (7) and closed by protective casing (8). Cultivator shares are installed between ripper (2) and tillage (4) rotors in middle of ripper rotor (2) drive teeth inter-trails. Cultivator shares fertilizer guides (10) are connected with fertilizer box (12) by fertilizer funnels (11). Protective cover (8) is equipped with soil surface leveler (13) and attachment bar (14), on which torsion springs (15) trailers cereal crops sowing shares (16) are installed, connected with seed box (18) by seed tubes (17). Further coverers (20) and roller (21) with treatment depth adjustment mechanism (22) are arranged. Shares (16) initial torsion spring (15) compression is set by means of common for group of shares (16) limiting beam (19) position installation. Limiting beam (19) is fixed in slots of attachment bracket. Limiting beam (19) lower fixed position provides for not more than of ¹/₂ of torsion spring (15) force, and upper fixed position is for not less than of ¹/₂ of spring (15) force.

EFFECT: such design solution is aimed at improvement of design reliability and improvement of sowing quality.
