摘要
FIELD: agriculture.;SUBSTANCE: system (50) contains furrow opener (20), which has pair of disks (52) located against each other at an angle (α). Each disk (52) has inboard side (58) and exterior (60), at that inboard sides (58) are turned to each other, and exteriors (60) are located opposite each other. Each disk (52) has relatively movement direction (44) forward edge (54) and back edge (56). Furrow closer contains pair of wheels (22) units of depth and closing of seed furrow. Each wheel (22) has inboard side (62), and inboard sides (62) are turned to each other and located to adjacently-corresponding exteriors (60) of the disks (52). Each wheel (22) has forward edge (64) and back edge (66). The forward edge (64) is located between the forward edge (54) and the back edge (56) of corresponding disk (52). The back edge (66) is located relatively to movement direction (44) behind back edge (56) of corresponding disk (52). The agricultural machine contains tool carrier (14) and at least one system of opening and closing of the seed furrow in the soil leaning against the tool carrier (14) described above.;EFFECT: system provides high accuracy of interval for seeding material and reduction of compaction of lateral walls of furrow and allows to improve quality of closing of furrow when moving on curved trajectories and on various soils.;10 cl, 3 dwg
