ROLLER-SPHERICAL DRILL SHARE

摘要

FIELD: agricultural engineering, in particular, covering device for drills. SUBSTANCE: share has left and right spherical disks and circular disk-type cutter projecting beyond disk edge. Share is removably mounted on drill. Two leaf springs with grips and rim are fixed on inner side of one half of share. Alternating catches and stops are positioned in equally spaced relation on rim. Fingers are mounted on tines on other half of disk at its inner side. Catches of leaf springs and fingers are strictly oriented relative to central openings of disks. Cutter disk is mounted on rim provided with catch receiving slots made in rim inner side. Such construction allows furrows for seeds with compacted bottom and side walls to be formed. EFFECT: increased service life, simplified construction and increased crop yield. 6 dwg
