Interchangeable Metering Shaft for Pneumatic Seeders

Key Benefits

Interchangeable Metering System

Select the appropriate metering shaft for different seed types and application rates.

One Seeder for Multiple Crops

Change the metering shaft to adapt the pneumatic seeder to different crops and materials.

Accurate Seed Metering

The correct shaft geometry helps regulate seed flow according to the required application rate.

Suitable for Different Seed Sizes

Different shaft configurations can be selected for fine, medium and larger granular seeds.

Quick Shaft Replacement

The metering shaft can be changed without tools, simplifying crop changes and routine setup.

Designed for YongXiang Pneumatic Seeders

Compatible metering shafts are selected according to the seeder model, seed type and application requirements.

Interchangeable Metering Shaft System

Different seeds have different physical characteristics and application requirements. The YongXiang pneumatic seeder therefore uses interchangeable metering shafts to match the metering system to the material being applied.

Each shaft is designed for a specific range of seed characteristics and application rates. Selecting the correct shaft helps maintain a controlled and consistent flow of seed into the pneumatic delivery system.

The metering shaft is driven by the electric metering system, while the central control system regulates shaft speed according to the selected application rate and forward speed.

This combination of shaft selection, electric metering control and radar speed synchronisation allows the same pneumatic seeder to be configured for different crops without replacing the complete seeding system.

Select the Right Metering Shaft for the Seed

The appropriate metering shaft should be selected according to the seed type, seed size, target application rate, working width and forward speed.

Fine seeds and larger granular seeds require different metering characteristics. Using the correct shaft helps maintain stable material flow and improves metering accuracy, particularly at low application rates.

If the required seed or application rate is not listed, YongXiang can recommend a suitable metering shaft based on the seed type, application rate, working width and operating speed.

How the Metering Shaft Works

1. Select the Metering Shaft

Choose the shaft according to seed type and application rate.

2. Install the Shaft

Replace the metering shaft without tools.

3. Calibrate the Seeder

Carry out a calibration test to confirm the required application rate.

4. Meter and Deliver the Seed

The electric drive rotates the shaft while the pneumatic system carries the metered seed through the delivery hoses.

Integrated with YongXiang Metering Control

The metering shaft works together with the YongXiang electric metering system and speed control.

After selecting the appropriate shaft, the operator enters the required application rate and performs a calibration test. During operation, the radar sensor provides forward-speed information to the control system, which adjusts metering shaft speed to maintain the selected application rate.

This means that changing the metering shaft is not simply a mechanical crop change; it forms part of the complete metering and control process.

Compatible YongXiang Pneumatic Seeders

The interchangeable metering shaft system is designed for use across the YongXiang pneumatic seeder range. Shaft selection depends on the seeder model, hopper configuration, seed type and required application rate.

Frequently Asked Questions

Can one metering shaft handle different crops?

One shaft may cover a range of seed types with similar metering characteristics, but the recommended shaft depends on seed type, seed size and application rate. Selecting the correct shaft helps maintain accurate and consistent metering.

How do I choose the correct metering shaft?

Shaft selection depends mainly on the seed type, target application rate, working width and operating speed. YongXiang can recommend a suitable shaft based on these parameters.

Does changing the metering shaft require tools?

No. The metering shaft is designed for quick replacement without tools.

Can the seeder be used for both small and large seeds?

Yes, different metering shaft configurations allow the pneumatic seeder to be adapted to different seed sizes and application rates.

Do I need to recalibrate after changing the shaft?

Yes. A calibration test should be carried out after changing the metering shaft to confirm the required application rate.
