APPARATUS FOR FLAT PLOWING Russian patent published in 2003 - IPC

FIELD: agricultural engineering. SUBSTANCE: apparatus has frame, hitch, rotary bar with plow bodies rigidly attached to rotary bar, hydraulic cylinder mounted on frame through vertical pivot joint and adapted for rotating said bar, carrier wheels with plow depth adjustment mechanism, and apparatus for retaining bar in operating positions. Hitch is connected to frame through horizontal pivot joint positioned in longitudinal-vertical plane in advancement direction. Plow carrier wheels are pivotally connected through parallelogram mechanism cooperating with adjusting bolts of hitch. Upper link of parallelogram mechanism is positioned for rocking around horizontal pivot joint of hitch and lower link for rocking around horizontal pivot joint mounted on frame in longitudinal-vertical plane. Such construction eliminates movement of tractor wheels and plow carrier wheels over plowed field. EFFECT: simplified construction and improved quality of soil plowing. 3 dwg
