COMBINED FURROWING AND SEEDING APPARATUS Russian patent published in 2007 - IPC A01B49/06 

FIELD: technique for simultaneous cutting of small-sized irrigation furrows to be sown with seeds and for continuous sowing of farm crops during surface irrigation on flooded flow-through furrows.

SUBSTANCE: combined furrowing and seeding apparatus has frame to be coupled to tractor, carrier-drive wheels provided on frame, seeding box mounted on frame and furnished with seeding devices connected through seed guides to shares. Mounted on frame front bar are furrow forming devices including working tools, compaction roller, and mechanisms for setting of working tools in transport position. Furrow forming hoes are fixed on vertical columns. Front hoes are set for depth of soil layer to be cut, said depth making 1/2 (H+a), and rear hoes are set for depth (H+a), where H is furrow depth and a is seed embedding depth. Front hoes are formed A-shaped, flat and are equipped with cylindrical left-hand and right-hand moldboards. Rear hoes are made combined at two levels, with lower level hoe being made A-shaped and flat. Upper-level hoe is made A-shaped and flat and is provided with cylindrical left-hand and right-hand moldboards. Upper-level hoe is positioned at an angle exceeding angle of crumbling of soil to be sown. Each furrow forming device is spring-loaded relative to frame. Trapezium-shaped furrow compacting devices are fixed on compaction roller disposed on frame of carrier-drive wheels and are moved depending on furrow spacing. Compaction roller is positioned in front of seeding devices equipped with two-disk shanks.

EFFECT: reduced consumption of power, decreased application of loading onto soil, uniform seeding on surface irrigation plot for irrigation on small-sized flooded furrows to be sown, even sprouts which guarantee high yields.
