CULTIVATING DEVICE Russian patent published in 1995 - IPC

FIELD: agricultural engineering. SUBSTANCE: cultivating device has additional tools installed under each pedal and made in the form of two hinge-joined plates with a radius of curvature equal to the length of the front tie-rod of the parallelogram suspension. The upper plate is fixed to the upper part of the parallelogram suspension front tie-rod, and the tangent to the point of their attachment forms an angle of 90 C with the axis of the front tie-rod. The lower plate has longitudinal ribs and is linked to the upper part of the parallelogram suspension rear tie-rod by means of a lever with a slot rigidly secured on it, connecting rod with a roller, bell-crank and tie-rod. The tie-rod is hinge-joined between the lower plate and one end of the bell-crank, which is installed on the axle of connection of the front and rear tie-rods of the parallelogram suspension. The connecting rod is hinge-joined to the other end of the bell-crank and connected to the rigidly installed lever by means of a roller positioned in its slot. The rigidly secured lever with a slot is made in the form of a bent plate with a radius equal to the length of the parallelogram rear tie-rod. The slot axis tangent forms in the point of attachment an angle of 90 C with the axis of the parallelogram suspension tie-rod. EFFECT: improved design. 4 dwg
