Nowadays, agriculture has put forward higher requirements for both the quality and efficiency of seedling cultivation. The 2BP-850 drum-type seedling nursery sowing machine perfectly meets the needs of the majority of growers, featuring precise sowing, high working efficiency, fully automatic production line operation, and a wide range of applications.
This production line is composed of three functional sections, namely the substrate tray-filling and leveling machine, the drum-type precision seeder, and the backfilling and leveling integrated machine, achieving full-process automation from substrate filling to sowing completion. The first section is the substrate filling section, which can evenly fill nursery substrate into the cells of plug trays and remove excess substrate through a leveling device, ensuring consistent filling volume in each cell and providing a uniform growth environment for seed germination. The second section is the drum-type precision sowing section. The drum uses vacuum negative pressure to absorb seeds, and as the drum rotates, the seeds are precisely released into the corresponding plug tray cells, achieving one seed per cell and greatly reducing seed consumption as well as the labor costs of manual seedling supplementation and thinning. The third section is the soil covering section, which covers a thin layer of soil over the surface of the sown plug trays, ensuring close contact between the seeds and the substrate and completing the entire sowing operation.
Compared with traditional manual sowing, the advantages of this seedling nursery sowing production line are very significant. Its operating efficiency can reach thousands of trays per hour, which is about fifty times that of manual sowing. The drum adopts a convex nozzle design, which has strong adaptability to seeds of various shapes. Whether the seeds are round or flat, they can all be precisely absorbed. This drum-type seedling nursery production line is applicable to a wide range of crops, including small and medium-sized seeds such as pepper, tomato, eggplant, scallion, onion, chive, Chinese cabbage, cabbage, cauliflower, broccoli, celery, lettuce, cucumber, melon, Hami melon, and watermelon.
In practical applications, its advantages are very obvious and it has been widely used. It not only solves the problems of labor shortage and high labor costs during the busy farming season, but also provides a reliable guarantee for the standardized and batch production of seedling cultivation.
