The following section provides information on the implement structure
and the functions of the individual components.
Fig. 29
Precision airplanters place the seed grains individually in equal,
adjustable distances in the ground. In each row one sowing unit
works with its own seed hopper (Fig. 29/1).
The seed is sucked into the holes in the rotating singling discs. One
suction blower fan (Fig. 29/2) creates the required vacuum. At the
lowest point of the singling disc, the vacuum is released and the
seed grain falls into the seed trench created by the seeding coulter
(Fig. 29/3).
After sowing, the seed is covered evenly and pressed in place by the
closer (Fig. 29/4) and the press roller (Fig. 29/5).
The drive wheels of the precision airplanter drive the singling discs.
The speed of the singling discs is set via the setting gearbox and the
secondary gears. Gearbox speed changes alter the spacing of the
grains in the ground. Individual sowing units can be electronically
switched off, e.g. using the AMASCAN
+
on-board computer
(optional).
The suction air fan (Fig. 29/2) is driven by the tractor PTO shaft or by
a hydraulic motor.
Track markers (Fig. 29/6) mark the field connection run either in the
centre of the tractor in the tractor track (except ED 302).
For under root fertilising (optional), precision airplanters are fitted
with fertiliser coulters (Fig. 29/7) which deposit the fertiliser normally
at 6 cm distance (adjustable) next to the seeding coulters (Fig. 29/3)
in the ground.
The fertiliser placement depth is adjustable. The fertiliser is stored in
the hopper (Fig. 29/8) or in the front tank.
Using the filling auger (Fig. 29/9, option), the fertiliser hopper can be
easily filled.
