COMBINATION OF SEMIMOUNTED ROLL-OVER PLOW AND APPARATUS FOR PRESOWING TILLAGE OF SOIL Russian patent published in 1997 - IPC

FIELD: agricultural engineering. SUBSTANCE: combination of semimounted roll-over plow and apparatus for presowing tillage of soil is adapted to be hitched to pulling device. Plow has hauling frame, beam mounted on frame and pairs of roll-over plow bodies. Carrier beam is positioned on mounting frame by means of device providing rejoining of beam between first and second working positions of each pair of plow bodies. Apparatus for presowing tillage of soil is made in the form of roll which is connected with carrier beam of plow by connecting beam. Connecting beam is mounted on carrier beam between front and rear pairs of plow bodies and positioned outside and behind plow to transfer part of plow weight to presowing soil tillage apparatus. Pivot joint device for connecting beam with presowing soil tillage apparatus provides transverse travel of plow and mentioned apparatus one relative to the other and displacement of carrier beam between first and second working positions. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 8 cl, 3 dwg
