PLOW Russian patent published in 1997 - IPC

FIELD: agricultural engineering. SUBSTANCE: plow has frame 1 carrying plow bodies 6. Rippers 2 positioned behind each plow body 6 have inclined tine with cutting edge and chisel 3. Trailing edge 7 of plow body 6 is faced toward ripper tine riveted portion. Cutting plane of plow body shares is positioned above cutting plane of ripper chisel 3. Arrangement of plow body and ripper is determined by ratios: ; c ≥ h_p; d ≥ h_p; 0 ≥ a ≥ 3/4 b.k. , where c is distance in horizontal transverse-vertical plane from landward edge 11 of plow body of ripper chisel; b is plow body working width; k is coefficient taking into account overlapping (incomplete overlapping) of moldboard bodies in transverse-vertical plane; d is distance between parallel surfaces tangential to rear surface of moldboard body and to cutting edge of inclined part of ripper tine positioned at the level of blade 10 of share; a is distance between parallel vertical planes extending through plow body landward edge and cutting edge of inclined part of ripper tine positioned at the level of share blade. Such construction and parameters of plow ripper provide for joint operation eliminating repeated tillage of soil above share cutting edge. EFFECT: increased efficiency, reduced cost and improved quality of tilled soil. 3 cl, 2 dwg
