DEVICE FOR PRE-SOWING TILLAGE AND SOWING OF LARGE-FRUITED FOREST SEEDS Russian patent published in 2022 - IPC A01C7/00 

FIELD: forestry.

SUBSTANCE: invention relates to forestry, in particular to devices for pre-sowing tillage and sowing large-fruited seeds of forest crops. A device for pre-sowing tillage and sowing of large-fruited forest seeds contains a frame with a hitch, a spherical disk installed in the front part of the frame at an angle of attack with a blade for cutting, turning and laying sod outside the sowing furrow, a coulter, a wave disk designed for loosening the sowing furrow and mounted for rotation on an axle transversely fixed on the frame, a sowing unit of a reel-blade type with a chain drive from a wheel equipped with grousers, and a press roller. The skid-like supports are fixed on the frame. The diameter of the spherical disk D₁ is determined from the ratio D₁=(6.7-7.2)H, and the diameter of the wave disk D₂ is determined from the ratio D₂=(1.3-1.37)D₁, where H is the depth of the seed furrow.

EFFECT: invention allows to reduce energy consumption and improve the quality of pre-sowing tillage and sowing of large-fruited forest seeds.
