Abstract RU 2271641 C1

FIELD: forest industry, in particular, sowing of large-fruit seeds of forest crops, such as oak acorns.

SUBSTANCE: apparatus has frame, shank, seeding unit, covering roller, and slide-type supports. Three disk knives are disposed in parallel with one another in front part of frame and subsoiler-skim is positioned immediately rearward of subsoiler-skim. Wavy disk is positioned rearward of skim for rotation on immovable shaft fixed on frame. Diameters of disk knives are determined from formula: D₁=(2.5-2.6)H. Diameter D₂ of wavy disk is determined from ratio D₂=(1.05-1.1)D₁, where D₁ are diameters of disk knives, D₂ is diameter of wavy disk, H is seed furrow depth.

EFFECT: increased efficiency by providing simultaneous presowing treatment of soil and sowing of large-fruit forest crop seeds.
