Drum seeder Eco-Rouline

The Eco-Rouline drum seeder is suitable to process/handle coated and pelleted seeds and round naked seeds. The Eco-Rouline on the PSL–II can only work indexing (per row of cells on the tray).

The seeds are picked up from the seed hopper by means of a vacuum. The vacuum can be adjusted by means of a air tap on the control panel, the amount of vacuum can be red from the gauge. The seed hopper is mounted with the opening side along the surface of the drum. By changing the slope of the seed hopper the “efficient” surface for picking up the seeds can be changed. By enlarging the surface the result of picking up the seed can be increased. hopper can also increase the result.


After picking up the seed of the seed hopper the drum will rotate in opposite direction of the conveyor belt. On top of the drum the seeds will pass a blow off bar. For each nozzle in the length direction of the drum there are two blow off nozzles which will blow off eventually double seeds from the seeding nozzles. The air pressure of the blow off nozzles can be adjusted with an air tap on the control panel, the amount of vacuum can be red from the gauge. On the lowest point of the sowing drum the vacuum is released and the seeds drops in the cell. After seeding the nozzles are cleaned by blowing air through the nozzles. The air pressure for cleaning the nozzles can be adjusted by means of an air tap on the control panel, the amount of the pressure can be red from the gauge.
