The Hamilton Natural Seeder is the industry standard seeder, and the machine by which all others are judged. Ideal for the small to medium sized greenhouse operation, this machine delivers the versatility and accuracy you need and expect. There are three methods for indexing the tray under the seeder head:
This entry-level model utilises the same precision seeder used on some of our more expensive seeding lines but fitted with a hand operated mechanism to step plug trays line-by-line under the seeder. Trays are loaded in the front of the machine, and then indexed out by a hand ratchet system. The seeder is synchronised to the ratchet mechanism to seed into each line of the plug tray. This machine only requires a compressed air supply.
This model has a mechanism to index the plug tray etc. under the seeder for precise sowing of seeds. The mechanism is powered by compressed air and controlled by a microprocessor PLC to synchronise it with the seeder. In operation, the growing container is loaded under the front of the seeder. A microswitch starts the cycle, and the mechanism pushes the tray forward a row at a time, seeding each time until the tray, fully seeded, is re-presented to the operator, when the mechanism stops ready for the next tray. Dwell control and Multi-sow are now standard features (see below). A domestic single-phase electrical supply is required for this model.
This is the top-of-the-line Natural Seeder model, the fastest and most versatile of our Natural Seeder systems. The Seeder and Coverer are controlled by a microprocessor PLC to synchronise the tray with the Seeder. Set-up times when changing trays are exceptionally fast, and this model will sow all types of tray from plug trays to thin plastic flats and packs. The height of the conveyor is adjustable to match up with most proprietary filling and watering lines. Another bonus with this model is the multiple sow feature which can be set to sow 1, 2 or 3 seeds per cell before the conveyor advances to the next line. A Dwell function is also incorporated. As with all models variable speed is standard. A domestic single-phase electrical supply is also required for this model.
