SEEDS DISTRIBUTION DEVICE FOR PRECISION SOWING MACHINES AND PRECISION SOWING MACHINE COMPRISING SUCH A DEVICE

摘要

A seeds distribution device (1, 100) for precision sowing machines comprising a housing (860) for a seed selector disc which is mounted for rotation about a central rotation axis (Z), at least one ring of holes in the seed selector disc which is provided to transport seeds (S) over a circular trajectory (C), a first singulator (10, 110) and a second singulator (20, 120) which are mounted so as to be radially facing on the housing (60) at opposite sides of the circular trajectory (C) of the seeds (S) and the first and second singulator being distal and proximal with respect to the central rotation axis (Z) respectively, the first singulator and second singulator defining a disruptive selection path for the seed and being independently adjustable selectively to modify at least locally the disruptive path so as to eliminate duplicates of seeds from the disc without creating failures.
