2BP-850 drum type nursery seeding line serves as a complete automatic nursery production line. Three main units form the whole line: substrate filling machine, drum precision seeder, backfilling machine. Separate combination or split use of each unit supports convenient operation. Automatic completion of all working procedures includes soil covering, leveling, roller brushing, hole pressing, seeding and secondary soil backfilling. Connection with other nursery equipment such as substrate elevator or watering machine is available.
2BP-850 drum type nursery seeding line covers a wide application range. Small seeds include chili, tomato, eggplant, green onion, onion, Chinese chive, Chinese cabbage, cabbage, cauliflower, broccoli, celery and lettuce. Large seeds include cucumber, muskmelon, cantaloupe, watermelon and pumpkin. Replacement of matched seeding drum realizes switching of seed varieties.
Seeding accuracy for pelleted seeds of 2BP-850 drum type nursery seeding line reaches above 98%. Maximum production capacity hits 1000 trays per hour. Compatibility with multiple plug tray types includes standard 56*28cm plastic plug trays and floating trays.
Control system of 2BP-850 drum type nursery seeding line adopts Siemens PLC and servo control system. A 7-inch Chinese and English touch screen is equipped. Stable operation of the equipment supports 10 consecutive working hours without shaking or offset.
Working flow of 2BP-850 drum type nursery seeding line: Place plug trays on conveyor belt. Conduct soil covering. Adjustable thickness of covering soil and backfill soil ranges from 10 mm to 80 mm to guarantee uniform seeding depth. Carry out leveling and roller brushing to remove redundant soil on plug tray surface. Conduct seeding. Suction nozzles install on the drum. Vacuum generates inside the drum during operation. Positive pressure absorbs seeds, and negative pressure releases seeds to place one seed into each cell of plug trays. Replacement of drum realizes switching of seed varieties. Plug-in design of the drum supports easy assembly and disassembly. Conduct soil backfilling to finish the whole nursery seeding process.
