FLAT HOE FOR THE BASIC SUBSOIL TILLAGE Russian patent published in 2018 - IPC A01B35/26 A01B15/02 

FIELD: agriculture; mechanical engineering.

SUBSTANCE: invention relates to the field of agricultural engineering, in particular to the tools for subsoil tillage, prone to wind erosion. Flat hoe for the basic subsoil tillage contains a shoe connected to the beds that are curvilinear on the side of mounting the shares. On the beds the shares are fixed made of separate sections and having an angle of the blade crumbling, increasing from the tip of the share to its end. Each divided share is made convex toward an untreated bed in such a way that the concave non-working side is a part of a screw dump surface in the shape of the tool of the single-furrow plow, starting from the landward edge in the furrow direction at the length of the divided share, and the width of this screw dump surface is equal to the width of the share. Convex surface of the divided share is a smooth extension of the curved blade of the latter. Part of the screw dump surface has a guide curve starting from the joint line of the share with a moldboard on the plow-dump surface and at a height equal to the width of the divided share of the flat hoe. Numerical value of the radius of bending of the concave part of the divided share of the flat hoe increases from the tip to the end of the latter.

EFFECT: such a constructive solution ensures the elimination of soil sticking on the tool.
