SECTION FOR SEED-FERTILIZER SEEDER Russian patent published in 2007 - IPC A01C7/20 

FIELD: agricultural engineering.

SUBSTANCE: section for seed-fertilizer seeder has A-hoe, tine-fertilizer pipe, and seed guides. Section has two seed guides positioned behind tine-fertilizer pipe, and is equipped with disk knife and roller. Disk knife is positioned in front of tine-fertilizer pipe. Roller is mounted behind seed guides and provided with two circular lugs. Tine-fertilizer pipe is equipped at its front side with rigidity rib. Lower part of tine-fertilizer pipe is made wedge-shaped, with acute end being oriented in direction of advancement of seeder. Wedge and fertilizer pipe end are positioned at the level below cutting edge of A-hoe. Ends of seed guides are positioned under hoe and bent to the right and to the left respectively by value equal to half the width of spacing. Protrusions are provided on underside of hoe, at both sides of axis of symmetry, with gap between said protrusions being equal to half the width of spacing, so that lower ends of protrusions are below the level of cutting edge of hoe. Roller lugs are arranged opposite protrusions provided on A-hoe. Lower part of tine-fertilizer pipe has figured cut.

EFFECT: improved quality of seed embedding process and increased efficiency in utilization of applied fertilizers.
