FIELD: agricultural engineering; band sowing. ^ SUBSTANCE: invention is designed for sowing fodder grass. Proposed drill has frame with fitted on road wheels, depth adjuster, flat duckfoot ties, posts, pressure springs, support guide wheels on bars, seed hopper, distributors, transmission mechanism group depth adjuster of drill units, and colter beam. Drill consist of bars hinge-mounted on colter beam, furrowing rolls with rubber rim and suspension mechanisms being mounted on bars. They are formed by rods with springs. Cylindrical heads connected with distributors by seed tubes and seed distributing chutes are mounted on bars. Heads are installed with possibility of adjusting angle of tilting in longitudinal vertical plane. Seed distributing chutes are adjustable in height. Covering devices of drill are made in form of chain covers. They are secured after drill sections on one line with furrowing rolls. ^ EFFECT: provision of uniform distribution of seeds over tilled surface and uniform depth of seed covering. ^ 5 dwg |
