DRILL FOR TILLED CROPS Russian patent published in 2008 - IPC A01C7/00 

FIELD: agricultural engineering, in particular, equipment for sowing of tilled crop seeds and simultaneously for application of fertilizers.

SUBSTANCE: drill has furrow cutter mounted on frame having carrier wheels, hoppers for fertilizers and seeds, devices for pointed seed sowing and pointed application of fertilizers, and covering roll. Devices for pointed sowing of seeds and pointed application of fertilizers have single rotational drive kinematically connected with drill carrier wheel. Furrow cutter is formed as wedge to which shields-brackets are attached. Devices for pointed sowing of seeds and pointed application of fertilizers are formed as disks having similar diameters and equipped with single drive formed as gear. Said devices are arranged in single plane between shields-brackets. Disk for pointed sowing of seeds is positioned higher than disk for pointed application of fertilizer and has seed guide located in its lower part and adapted for forming cut in furrow wall above its bottom. Output opening of bottom is arranged in plane parallel to plane of disks and is offset relative to disk for pointed sowing of seeds backward in direction opposite to direction of advancement of drill.

EFFECT: improved process for synchronized feeding of tilled crop seeds and portions of fertilizers, reduced consumption of power for furrow forming process, and increased yield of farm crops.
