FIELD: agricultural engineering; hill seeding at precision distance between seeds. SUBSTANCE: row crop mounted drill has seeding drill units connected to main beam of frame and consisting of replaceable hopper with drilling mechanism and drill control corrector common for all drilling units. Drill control corrector is made in form of step mechanism built into carrier-bull wheel of drill consisting of four hollow guides rigidly coupled with rim of carrier-bull wheel with extensible rods fitted in spaces. Rods are mechanically coupled with rack-and-gear train on ends of which grousers are hinge-mounted. EFFECT: increased accuracy of bed forming. |
