The compressed air fan produces the overpressure
in the grain singling unit. The grains from the supply
area
1
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
2
. 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
3
. The seed is transferred to
the feed channel by the air current at the opto-sensor
4
. The opto-sensor monitors the grain singling unit.

4.9.2 Singling disc
The singling discs
1
are exchangeable and can
be adjusted for the operating conditions as well as
the seed characteristics. The blades
2
stir the
seed. The marking on the singling discs provides
information on the number of holes
3
and the hole
diameter of the singling disc. The ejection wheel
4
releases jammed seed and ensures that the singling
discs are clean.
