BROADCAST SOWING SHANK

摘要

FIELD: agricultural engineering.;SUBSTANCE: shank has A-hoe-cultivator, hollow column-seed guide, and seed distributor with vibration drive. Column-seed guide is located within casing of hoe tine. Gap between column-seed guide and casing is filled with elastic material. Vibrator is positioned at upper end of column-seed guide and seed distributor is positioned at lower end of column-seed guide. Seed distributor is formed as dead end pipe with longitudinal slot extending through the entire length of pipe in its rear and side walls to serve as seeding unit. Column-seed guide is connected to seed distributor and to hoe tine through elastic couplings. Position of feeding branch pipe of seed distributor may be adjusted in vertical plane, its lower end being positioned above lower edge of said slot.;EFFECT: improved quality of seed distribution and reduced metal usage owing to avoiding employment of seeding unit.;3 cl, 3 dwg
