ENERGY-SAVING PLOW Russian patent published in 2014 - IPC A01B15/08 

FIELD: agriculture.

SUBSTANCE: plow comprises a plow-bottom surface curved along two tautochronic-brachistochronic guide cycloids. The length of the guides exceeds four radii of the circle, generating the cycloid and is equal to L_min and L_max. The length is determined by the equations L_min, $$L_{\max }=4R(1-\cos \frac{\alpha }{2}),$$ where α is angles of rotation of the radius of the circle from the vertical, respectively, α≥ π, and $$\alpha \le \frac{7}{6}\pi ,$$ R is the radius of the circle that forms the cycloid is equal to where is the working width of the plowshare, φ is the angle between the cutting line of the plowshare and the wall of the furrow. Minimum height H_min of the mouldboard in the plane of installation of the smaller cycloid is equal or exceeds half the arch of the cycloid, H_min≥πR, and the height H_max of the mouldboard in the plane of installation of the greater cycloid exceeds $$H_{\max }\ge \frac{7}{6}\pi R.$$ The angle ε between the plowshare and the bottom of the furrow is regulated by joint line of the plowshare with the mouldboard, such as screws and washers with further tightening.

EFFECT: reduction of traction resistance of the soil and energy consumption to its processing.
