WORKING BODY OF THE CHISEL PLOW Russian patent published in 2023 - IPC A01B13/08 A01B15/02 E02F9/28 

FIELD: agriculture.

SUBSTANCE: working body of the chisel plow contains curved sections. The upper curvilinear section forms a variable height on the surface of the working body with two thickenings of the same height of 24 mm, one of which is located 78.5 mm from the nose cutting part, the second in the rear part. The thickenings in the longitudinal section of the working body are branches of a parabola, the top of which is located equidistant from the thickenings at a height of 14 mm from the base of the working body. The cross-sectional profile in the places of thickening of the working body has a flat base 60 mm wide, from the edges of which circles with a radius R=20 mm are erected, the centres of which are located on a flat base and connected by a radius R=68 mm. The cross-sectional profile of the working body at the top of the parabola, equidistant from the thickenings and located at a height of 14 mm, has a flat base 60 mm wide, from the edges of which circles with a radius R=10 mm are erected, the centres of which are located on a flat base and connected by a radius R=68 mm. The front part of the working body has a flat nose profile 6 mm high, passing into the side part along the radius R=20 mm. The change in the values of the radii erected from the edges of the flat base of the indicated sections changes along the working body from the value of the radius R=10 mm to the value of the radius R=20 mm along a sinusoid. The nose cutting part of the working body on a length of 78.5 mm is hardened by tempering with a surface hardness of 55 HRC.

EFFECT: reduced resistance to movement of the working body of the chisel plow in the soil due to the formation of a surface that creates less resistance.
