Wetland Rice Seeder with Side-Deep Fertilizer Application | 2BDGS-PF Series
Direct Rice Seeding and Side-Deep Fertilizer Application in One Operation
The YongXiang 2BDGS-PF Series combines pneumatic direct rice seeding with side-deep fertilizer application for wetland rice production. Mounted on a rice transplanter, the system meters and delivers seed and fertilizer independently, allowing both operations to be carried out in a single field pass.
The system is available in 8-, 10- and 12-row configurations, with working widths of approximately 2.0, 2.5 and 3.0 metres. Separate metering systems for seed and fertilizer allow the application rates of the two materials to be controlled independently.
Radar speed synchronisation adjusts metering according to transplanter speed, while the copying structure helps maintain consistent furrow depth as the machine follows changes in field contours.
Rice Seeding and Fertilizer Application Combines direct rice seeding with side-deep fertilizer application.
Dual Material Systems Provides separate metering and delivery for seed and fertilizer.
Side-Deep Fertilizer Placement Places fertilizer beside and below the rice seed zone.
Ground-Following Structure Helps maintain consistent working depth across changing field conditions.
Radar Speed Synchronisation Helps coordinate material application with transplanter speed.
Flexible Row Configuration Available in 8-, 10- and 12-row configurations.
Interchangeable Metering Shafts
Different metering shafts are available for different seed types, seed sizes and application rates.
Selecting the correct shaft helps maintain accurate metering, particularly when working with small seeds and low application rates.
The metering shaft can be changed without specialist tools, allowing the 2BDGS-PF series to be quickly adapted for different crops, cover crops and other compatible materials.
Intuitive Control and One-Touch Calibration
The 10-inch touchscreen control terminal allows the operator to monitor and adjust key seeding parameters from the tractor cab.
The system provides real-time information for seed level, working area and operating time. A dedicated one-touch calibration function makes seed-rate calibration quick, simple and hassle-free before field operation.
The control terminal works together with the metering drive and radar sensor to maintain the selected application rate during operation.
Consistent Metering with Electric Drive
The selected metering shaft and its rotational speed determine the application rate.
The 2BDGS-PF Series uses a 12V stepper motor to drive the metering system. The central control system continuously monitors and adjusts the metering speed according to the selected application rate and forward speed.
This speed-responsive control helps maintain consistent material delivery across changing field conditions.
Dual 12V Electric Fans for Pneumatic Seed Delivery
Two 12V electric fans generate the airflow required to transport metered material through the seed hoses to the distribution outlets.
The pneumatic delivery system provides an even flow of material across the working width, while protective mesh at the fan air intakes helps prevent straw and debris from entering the fan system.
Radar Speed Synchronisation
The radar sensor continuously measures forward speed and sends the speed signal to the control system.
The metering drive responds to changes in forward speed, helping maintain the selected application rate when the tractor slows down or increases speed.
This speed-responsive control supports consistent material application across changing field conditions.
Optional Seed Tube Blockage Monitoring
Optional seed tube blockage monitoring detects interruptions in material flow through the seed tubes.
Sensors monitor material flow below the discharge points and provide an alert on the control terminal if a blockage or missed delivery is detected.
This gives the operator an additional check on seed delivery and helps identify problems quickly during operation.
Agitator and Hopper Level Monitoring
A stainless-steel agitator is positioned above the metering shaft to help maintain a consistent material flow and reduce the risk of bridging in the hopper.
A low-level hopper sensor provides an instant alarm when the seed or fertilizer drops below the critical threshold, allowing the operator to plan refilling efficiently and prevent empty runs.
Flexible Outlet Configuration
Each outlet can be opened or closed independently using the supplied L-shaped plugs.
This allows the 2BDGS-PF Series seeder to be configured with fewer active outlets when a narrower working width is required.
The system can therefore be adapted to different implements and working widths without changing the main seeder unit.
Optional GPS Speed and Positioning
An optional GPS sensor can provide the vehicle's speed signal to the control system for speed-responsive metering.GPS speed data can be used as an alternative to radar speed signal.
An optional GPS positioning chip can provide positioning information for monitoring the seeder's field trajectory.
GPS positioning functionality is currently under overseas testing and should therefore be presented as an optional developing function rather than a fully established feature.
Real-Time Seeding Monitoring
An integrated camera allows the operator to monitor the seeding process from the touchscreen control terminal.
This provides an additional visual check during operation and helps the operator monitor the working condition of the metering system from the tractor cab.
Precision Row Drilling and Fertilizer Application
The 2BDGS-PF Series combines precision row drilling and fertilizer application on a rice transplanter, allowing both operations to be completed in a single pass.
Independent metering systems control the seed and fertilizer rates, while pneumatic delivery distributes both materials through dedicated outlets for consistent row application.
