COMBINED SHANK Russian patent published in 2003 - IPC

FIELD: agricultural engineering. SUBSTANCE: shank has flat disk mounted on carrier, fixed seed guide, and furrow cutting tool. Lower cut of furrow cutting tool is made in the form of part of carinate shank. Combined shank is provided with additional flat hoes, thinning A-hoe and ridge surface leveler. Additional flat hoes with cutting edges at their front parts are arranged in opposed relation on carrier. Each hoe has blade curved from disk surface at an angle to horizontal plane. Hoe tines are positioned on carrier so as to be repositioned through the height of disk. Apart from flat hoes furrow cutting tool has thinning A-hoe positioned in front of seed guide and in symmetry with respect to disk surface. Carinate part of shank is arranged on lower cut of tine of thinning A-hoe. Ridge surface levelers are made in the form of curved hoes facing one another and disposed on carrier so as to be repositioned in vertical plane. Combined shank may be used in row-crop drills. EFFECT: increased efficiency, improved cucurbitaceous crop yield and reduced wind erosion. 4 dwg
