PLOUGHSHARE Russian patent published in 2011 - IPC A01C7/20 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine building and may be used in sowing of crops. A ploughshare includes a vertical disk knife installed on the bracket, which ensures matching of the traction force direction with the ploughshare motion direction. A seed duct is installed behind the bracket. A furrow maker made of a wedge-like tip with a cheek coupled with the disk knife plane is installed in the lower part of the disk knife. The upper edge of the cheek is diverted away from the disk knife by an angle ensuring fixation of seeds along the row axis. The furrow maker is fixed to a bracket with the help of a side. Behind the cheek the furrow maker has vertical limiting sides connected to a furrow-closing hoe. The furrow-closing hoe is diverted towards the row axis and is arranged away from the furrow bottom at the height providing seeds gripping and covering with moist soil. A rolling wheel in the form of truncated cones oppositely installed with smaller bases is fixed to the bracket with the help of a leash. The height of the wheel installation on the soil surface may be controlled.

EFFECT: invention makes it possible to ensure coverage of seeds with a moist soil layer, and also to produce stable even shoots due to fixed sowing of seeds along the row.
