Large-scale seedling nurseries often face many challenges. Manual seeding is time-consuming and labor-intensive, with unstable sowing accuracy. Missed sowing and repeated sowing occur frequently. This not only wastes expensive seeds and leads to uneven seedling emergence, but also brings high labor costs. Traditional manual seedling raising can no longer meet the production capacity demands of modern farms. In conventional plug seedling production, manual seeding heavily relies on operators' experience. It is hard to ensure one seed per cell, resulting in seed waste. Meanwhile, manual sowing speed is limited, which greatly increases seedling production costs.
Some seedling sowing machines on the market have single functions. They can only finish the sowing process, while substrate filling, soil covering and other steps still need manual support. The whole system lacks stability. Errors easily happen during long continuous operation, and few types of seeds are compatible. To solve these pain points in the seedling industry, Hebei Kairuote launches the 2BP-850 Roller Type Seedling Sowing Line.
The 2BP-850 roller type seedling sowing line consists of three units: substrate filling and leveling machine, roller precision seeder, and backfilling & leveling integrated machine. The whole process from substrate filling, leveling and compaction, precision seeding to soil backfilling can be completed in one go with full automation. Only 3 to 5 workers are required, which greatly cuts labor costs.
The machine adopts the roller air-suction seed metering principle. Stable negative pressure picks up seeds to achieve precise single-seed sowing for each cell. The whole system is equipped with Siemens PLC servo control system from Germany, matched with Xinjie 7-inch Chinese & English touch screen for an intuitive and simple operation interface. Key components include Siemens relays (Germany), Panasonic photoelectric switches (Japan), SMC air-oil separators (Japan), and Omron contact sensors (Japan). Reliable hardware ensures stable long-time continuous operation.
This machine supports a wide range of seeds: pepper, tomato, eggplant, green onion, onion, Chinese chive, Chinese cabbage, cabbage, cauliflower, broccoli, watermelon, pumpkin, various leafy vegetables, flowers and Chinese medicinal herb seeds. The thickness of substrate filling and covering soil is adjustable, and it is compatible with plug trays of multiple sizes. One machine handles seedling orders of many varieties and improves equipment utilization for nurseries.
For pelleted seeds, the sowing accuracy reaches over 98%, empty cell rate is controlled within 1%, and seed breakage rate is lower than 0.1%. It greatly reduces missed sowing and repeated sowing, saves precious seeds and guarantees uniform seedling emergence.
The maximum working capacity can reach 1000 trays per hour, several times higher than manual seeding. Only a small number of workers are needed to place and collect trays, cutting workforce sharply.
The machine frame is made of Q235 sheet metal with plastic-sprayed anti-corrosion treatment, suitable for long-term use in factory seedling workshops. Core electrical and pneumatic parts adopt world-famous brands, featuring low failure rate and easy maintenance.
One machine meets seedling demands of vegetables, melons, fruits, flowers and Chinese medicinal herbs. The thickness of filling and covering soil can be adjusted, and multiple plug tray sizes are supported. It can deal with multi-variety seedling orders and raise equipment utilization rate of seedling bases.
Targeting industry pain points, the 2BP-850 roller type seedling sowing line reduces costs and improves efficiency for seedling raising. Whether for small and medium-sized seedling nurseries or large-scale seedling enterprises, this line simplifies seedling procedures, saves costs and improves seedling quality, acting as your reliable partner. Our factory is located in Baoding, Hebei. Factory visits and machine tests are available. Welcome seedling practitioners worldwide for inquiries and business talks.
