Automatic tray seeder

Drum Seeder - Standard or MaxiPro The Hamilton Drum Seeder is the flagship of our range of seeding machines. Fast, accurate, and versatile, this compact high-speed production machine is ideal for the grower who needs high output with minimum down-time. How it works The drum has galleries along its length which connect the pick-up holes (via a rotary valve) to a vacuum for seed pick-up, low pressure air for release, and a high pressure cleaning blast, in sequence, as the drum revolves. The seed is fed via a hopper into the valley between the drum and rear roller, which rotate in opposite directions. This agitates the seeds and makes them flow along the valley to the pick-up position. Vacuum is applied to the holes, which picks up the seeds and carries them under two air curtains to remove multiple pick-ups. The seeds are then carried round to the discharge position where the vacuum is replaced by low pressure air to discharge the seeds accurately into the tray. Immediately after discharge, the holes are cleaned by a high pressure air blast before returning to the pick-up position, when the cycle repeats. The drum is driven by a hybrid stepper motor, linked electronically to a speed pick-up on the conveyor. As the tray passes under the seeder it breaks an infra-red beam, which starts the drum rotating in perfect timing with the conveyor belt.
