SYMMETRICAL HANGER FOR WORKING TOOLS Russian patent published in 2005 - IPC

FIELD: agricultural engineering, in particular, equipment for creating cultivators of novel constructions.

SUBSTANCE: hanger for plow cultivator working tools has flat base with stops, two side frames adapted for crosswise pivotal connection with one another, springy pressure mechanism, and two wheels arranged in symmetry and spring-loaded on horizontal beam frame for independent feeling of field surface irregularities. Horizontal beam frame is pivotally connected with side frames. Springy pressure mechanism has coil-type compression springs put onto bars, which are pivotally and symmetrically attached with their upper ends to base and pivotally and symmetrically attached with their lower ends to cross-pieces of beam frame. Wheels are mounted on trapezium-shaped frames pivotally connected with beam frame and with wheels. Side frames are positioned for feeling of field surface irregularities independently of similar feeling by wheels owing to slots made in lower and mid parts of side frames.

EFFECT: wider operational capabilities and simplified construction.
