AMELIORATING TILLAGE TOOL Russian patent published in 2003 - IPC

FIELD: agricultural engineering. SUBSTANCE: ameliorating tillage tool has frame, main slitter and additional slitters. Tines of main and additional slitters are mounted on frame for individual transfer to operating and transport positions. Tines are mounted on frame through cylindrical pivot joint, which is positioned for angular and axial displacement. Pivot joint axis is aligned with axis of symmetry of frame. Pivot and mounting sleeve are arranged in pairs on pivot joint surface perpendicular to axes of rotation in equally spaced relation one with respect to another. Pivot and sleeve pair is adapted for attachment of mounting part of main and additional slitter tines on frame. Cylindrical pivot joint is provided with rotation mechanism and blocking mechanism, which is made in the form of shaft and U-shaped slots. Shaft is mounted in diametrical plane at the end of frame beam cylindrical part. Blocking mechanism is equipped with thrust mounted on top part of longitudinal frame beam forward of cylindrical pivot joint. Rotation mechanism is made in the form of pair of levers inclined to axis of symmetry of cylindrical pivot joint. Free ends of levers are equipped with handles. Each finger for fixing slitter tine in operating and inoperative position is made quick detachable. EFFECT: improved quality of soil tillage and increased efficiency in soil erosion control. 3 cl, 10 dwg
