OVERALL DRILL FOR SEEDS OF COMPOUND GRASS MIXTURE, PARTICULARLY, FOR DRILLING SEEDS ON RESTRICTED FIELD AREAS Russian patent published in 1997 - IPC

FIELD: agricultural engineering. SUBSTANCE: drill has frame 1, supporting wheels 2,3, hopper 4 with seeding units, drive with seeding unit and covering roller 5. Drill has two rows of furrowers 18,19 having concave spring tines, moldboards and working blades positioned on ends. Spring tines of one row are offset relative to tines of other row and mounted on rotary shaft so, that penetration depth may be varied and they may be moved to transport position. Hopper has device for distributing seeds along drill width. Seed distributing device is positioned between rows of furrowers and is made in the from of slit funnel 14 mounted for effectuating oscillating motions. Covering roller 5 is provided with ground-engaging members and primary drive member for seeding units. EFFECT: increased efficiency, simplified construction, enhanced reliability in operation. 10 cl, 16 dwg
