WORKING MEMBERS SUSPENSION MECHANISM Russian patent published in 2014 - IPC A01B35/00 A01B39/00 

FIELD: transport.

SUBSTANCE: suspension mechanism is made in the form of parallelogram the upper horizontal side (bracket) of which is rigidly fixed on frame. To the lower horizontal side (beam) of parallelogram working member is fixed. The front part of beam rests on two wheels symmetrically shifted in transversal direction relative to suspension mechanism longitudinal axis and is fitted in holder by means of bearing. The holder is pivotally connected with front tilted suspension link. Two rear links are made as spring-loaded rods with heads which rods are symmetrically shifted in longitudinal direction relative to suspension mechanism longitudinal axis. The rear links are pivotally connected with transversal consoles. The consoles are secured in the beam. To the rear part of bracket, retainers are pivotally connected which retainers form Assur groups of the third class with tilted suspension links.

EFFECT: higher quality of soil treatment due to providing possibility to copy transversal contour of cultivated field and to reduce clogging of central working member.
