2BZP-1100 Automatic Rice Nursery Tray Seeding Line (Complete Equipment Set) — Product Overview

The 2BZP-1100 is a high-capacity, fully integrated tray seeding line designed for commercial rice nurseries, seedling production bases, and agricultural cooperatives with demanding seasonal workloads. As a complete equipment set, it consolidates the entire tray-seeding process — conveying, soil spreading, watering, precision seeding, covering, and final watering — into one continuous, automated workflow. Delivering a proven hourly output of 1,100–1,150 trays within a remarkably compact 560 cm footprint, it offers an exceptional balance of maximum throughput and space efficiency for professional seedling operations.

Key Features

Fully Automated Workflow with Dual Watering: The machine executes the complete seeding cycle — conveying, soil spreading, first watering, seeding, covering, and final watering — in one uninterrupted pass. The double-watering design thoroughly moistens both the seedbed and the covering layer, locking in moisture for superior germination.

Wheel-Belt Soil Delivery System: Both the soil spreader and the covering unit adopt a wheel-belt delivery design, providing smooth, continuous, and uniform soil distribution with stable metering performance at high line speed.

Right-Sized 35L + 30L Soil Boxes: The 35-liter bed-soil box and 30-liter covering-soil box are matched to the machine's rapid cycle rate, keeping refill intervals short and production continuous.

Grooved-Roller Seeder with Stepless Adjustment: The seeding unit adopts a grooved-roller metering mechanism with fully stepless seed-rate adjustment, enabling infinitely precise control of seeding density for hybrid rice, conventional rice, and different regional planting requirements. The 20-liter seed box is optimized for the line's high-speed cycle.

Adjustable-Plate Brush Leveling: An adjustable-plate brush finishing system evens the covering soil layer to a consistent, controllable thickness, producing a smooth, uniform seedbed surface.

Chain + Belt Dual Transmission: The combined chain-drive and belt-drive transmission delivers smooth, synchronized tray transport with reliable power transfer and low maintenance requirements.

Compact Fixed Structure: The stationary frame measures 560 * 53 * 103 cm — significantly shorter than comparable 1,100-tray lines — with stable leg supports ensuring vibration-free operation.

Energy-Efficient Electric Drive: A single 300W electric motor powers the entire line, delivering outstanding output-per-watt with near-zero operating cost, and quiet, clean indoor operation.

Functions

Tray Conveying: Automatic infeed and synchronized high-speed tray transport along the full-length conveyor.

Soil Spreading: Uniform bed-soil distribution via the wheel-belt spreader to form a consistent seedbed base.

First Watering: Controlled moistening of the seedbed to prepare optimal germination conditions.

Precision Seeding: Metered, evenly distributed seeding via the grooved roller with stepless rate adjustment.

Covering & Leveling: Uniform top-soil covering followed by adjustable-plate brush leveling for a flat, consistent finish.

Final Watering: A second watering pass settles the covering layer and locks in moisture, ensuring trays are nursery-ready upon discharge.
