Seedling Sowing Equipment Engineered to Optimize Seedling Germination Rates and Streamline Nursery Production Processes

2BP-1000 Automatic Rice Nursery Tray Seeding Machine — Product Overview

The 2BP-1000 is the flagship model of our stationary-type automatic rice seeding line series, engineered for large commercial rice nurseries, seedling production bases, and agricultural cooperatives with maximum seasonal demand. Built around a fully integrated conveyor system, the machine completes the entire tray-seeding process — conveying, bottom soil spreading, compaction, watering, precision seeding, and covering — in one continuous, automated cycle. With an industry-leading hourly output of 1,000 trays or more, it is the ultimate solution for growers who need to complete large-volume nursery preparation in the shortest possible window.

Key Features

• Fully Automated Six-Stage Workflow: The machine executes the complete seeding cycle — conveying, soil spreading, compaction, watering, seeding, and covering — without manual intervention between stations, ensuring consistent, repeatable quality across every tray.
• Belt-Conveyor Soil Delivery System: Unlike conventional gravity-fed designs, both the bottom soil spreader and the covering soil device adopt belt-conveyor delivery, providing smoother, more uniform soil distribution and stable performance at high operating speeds.
• Dual 50-Liter Soil Boxes: Generous-capacity hoppers for bed soil and covering soil support extended continuous runs, minimizing refill stops during peak production.
• Precision External-Groove-Wheel Seeder: The seeding unit adopts an external groove-wheel metering mechanism with 14 adjustable seed-rate positions, allowing precise control of seeding density for hybrid rice, conventional rice, different tray specifications, and regional planting requirements. The 32-liter seed box ensures long, uninterrupted operation.
• Rotary-Brush Leveling: A rotary brush finishing system gently evens the covering soil layer, producing a smooth, uniform surface that promotes even moisture retention and uniform germination.
• Roller-Chain + Conveyor-Roller Transmission: The robust chain-gear and roller drive system delivers smooth, synchronized tray transport with minimal slippage, engineered for continuous heavy-duty operation at full throughput.
• Compact Fixed Structure: Despite its class-leading capacity, the stationary frame maintains the same well-balanced 866 × 54 × 114 cm footprint as smaller models, installing easily in workshops or nursery houses with stable, vibration-free leg supports.
• Electric Drive, Low Running Cost: Powered by a single 370W electric motor, the machine delivers exceptional output-per-watt, runs quietly and cleanly indoors, and requires no fuel.

Functions

• Tray Conveying: Automatic infeed and synchronized transport of nursery trays along the full-length roller conveyor at high line speed.
• Bottom Soil Spreading: Uniform distribution of bed soil via the belt-conveyor spreader to form a consistent seedbed base.
• Compaction: Even pressing of the soil layer to achieve ideal firmness for seed placement.
• Watering: Controlled moistening of the seedbed to create optimal germination conditions.
• Precision Seeding: Metered, evenly distributed seeding via the external groove wheel with 14 selectable rate positions.
• Covering & Leveling: Uniform top-soil covering by belt conveyor, followed by rotary-brush leveling for a flat, consistent finish.
