The compressed air fan produces the overpressure
in the grain singling unit. The grains from the supply
area
adhere to the holes of the singling disc due
to the overpressure. The rotating singling disc guides
the singled seed past the scrapers. The scrapers
remove excess seed grains
. The excess seed
grains fall back into the supply area. On the opto-
sensor, the holes of the singling disc are closed by
the hole covering roller
. The seed is transferred to
the feed channel by the air current at the opto-sensor
. The opto-sensor monitors the grain singling unit.

4.8.2 Singling disc
The singling discs
are exchangeable and can
be adjusted for the operating conditions as well as
the seed characteristics. The blades
stir the
seed. The marking on the singling discs provides
information on the number of holes
and the hole
diameter of the singling disc. The ejection wheel
releases jammed seed and ensures that the singling
discs are clean.
