OVERVIEW
3.6 METERING BOX
Single-seed dosing system in the metering units has been designed to select the seeds individually, so that they
are placed in the furrow keeping a distance between seeds set previously by the user (see section 6.1 PLANTING
DISTANCE BETWEEN SEEDS).
Main parts of the metering box:
1. Seed selector: selects a single seed for each seed disc’s hole.
2. Seed disc: distributes the seeds.
3. Seed ejector: helps the seed to fall in the right direction.
4. Counter-selector slide: prevents the selector from breaking its tip because of a seed.
5. Central slides.
6. Seed falling slide: it turns o the suction when the seed needs to be detached from the
seed disc.
7. Seed entering gate to the metering box: adjusts the entrance of the seed into the mete-
ring box.
8. Brushes: they clean seed residue from the seed disc.
9. Inspection gate: it allows you to see inside the metering box when the machine is run-
ning to perform the required adjustments.
10. Emptying gate: it empties the seed hopper.
11. Seed selector adjuster.
Each type of seed needs the appropriate seed disc (2, Fig. 3.8), since the seed’s size, spacing between plants,
etc, require specic discs with specic number of holes to control the distance between planted seeds. Besi-
des, the holes need to be big enough to contain a single seed.
