PLOUGHSHARE OF SEEDER-CULTIVATOR Russian patent published in 2010 - IPC A01C7/20 

FIELD: agriculture.

SUBSTANCE: ploughshare comprises centre hoe, hoe stand, receiver fixed to hoe, under-hoe space arch wing flaps, distributor of sown material. Distributor of sown material is arranged in the form of wedge-like splitter with two sloping surfaces. Receiver is arranged in the form of rectangular pipe with partition that separates it into two channels. Back wall of receiver is arranged with slope in direction of ploughshare motion, providing for reduction of speed of seeds dropping onto wedge-like splitter with two sloping surfaces and prevention of seeds scattering from wedge-like splitter with two sloping surfaces outside specified width of sowing band. Wedge-like splitter with two sloping surfaces is installed below wing flaps of under-hoe space arch with a slope in direction that is opposite to direction of ploughshare motion.

EFFECT: structural design will make it possible to provide for even distribution of the main mass of seeds in the part of furrow, which is not covered with a trace of back row hoes.
