FIELD: agriculture; machine building.
SUBSTANCE: invention relates to agricultural machine building, particularly to an assembly of adjusting depth for a disk ploughshare or another furrows cutting device. Due to that the eccentric cam of the depth adjustment assembly with its outer surface engages, prevented is rotation of the calibration lever of the gauge wheel. Since turning the gauge wheel lever sets the position of the gauge wheel relative to the furrows cutting device, limited turn of the lever sets the depth of cutting furrows for the furrows cutting device. Eccentric cam may have a smooth outer edge making a nondiscrete range of positions, or a profile of the outer surface, which defines discrete positions setting the depth. Eccentric cam is shifted to be engaged with the receiving device by means of a pin and a spring, but overcoming the shift enables instant release and rotation of the cam for resetting the eccentric cam.
EFFECT: such design solution is aimed at more accurate adjustment of depth of the disk ploughshare, as well as at convenience of such adjustment.
