Metering Box - Sola PROSEM K BASIC Series Starting Manual

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 off 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 specific discs with specific number of holes to control the distance between planted seeds. Besi-
des, the holes need to be big enough to contain a single seed.
