PLOUGHSHARE Russian patent published in 2021 - IPC A01C7/20 

FIELD: agriculture.

SUBSTANCE: ploughshare contains a case, a leash for attachment to a frame, two flat pointed discs for furrow formation, a plate located between them for feeding seeds to a seed guide into the furrow, and a cleaner for cleaning inner planes of discs. On the case, in the front part in the direction of the ploughshare movement, a U-shaped casing made of wear-resistant steel is rigidly fixed to protect seeds from being captured by discs, having a groove for adjusting its position and subsequently fixing it with two bolts. Front working faces of the casing are made rounded to align the bottom of the furrow and form a compacted bed for seeds, and the seed guide into the furrow is made in the form of a groove in the casing. In the latter, an additional cutout is also made in the form of a groove open on one side for uniform distribution of seeds along the depth and at the bottom of the furrow, fed from the guide, wherein the groove and groove of the casing are protected by cheeks that protect against untimely shedding of the soil and ensure smooth closure of the bottom of the furrow with seeds by a non-destroyed layer of soil.

EFFECT: invention will improve the accuracy of seed embedding.
