ADDITIONAL FIXTURE TO POLYDISK TILLAGE IMPLEMENT Russian patent published in 2009 - IPC A01B5/00 A01B7/00 

FIELD: agriculture.

SUBSTANCE: additional fixture is represented by a plate attached to the outer disk concave side with the help of a vertical support so that to provide for regulation and lock of the plate position height. Inclined to the horizontal plane, the plate forms with the latter acute angles both lengthwise and crosswise. The plate is arranged in such a way that its edge proximal to the disk is higher than the outlying one and the front edge is higher than the rear one. The plate is attached to the lower section of the hub strut. The hub is clearance-fitted onto the trunnion with the help of a radius rod screwed into the hub bracket so that to enable its displacement angle lock. The trunnion axis is parallel to that of the disk rotation. The plate is spring-mounted and equipped with an adjustable element limiting the angle of displacement relative to the trunnion axis.

EFFECT: improvement of tillage quality and energy efficiency.
