8 Row Pneumatic Onion Seeder

    This 8-row pneumatic onion seeder innovatively adopts a "dual-disc parallel" structure, a globally leading design that achieves three major breakthroughs:First, it compresses row spacing to a minimum of 10 cm, significantly improving land utilization;Second, through reduced seeding height and error-control technology, it achieves millimeter-level sowing accuracy;Third, the modular design increases the cleaning and maintenance efficiency of the suction discs by 60%.The equipment supports intelligent switching between single-seed and multi-seed sowing modes, with customizable row and plant spacing. While ensuring seedling emergence rates, it saves approximately 30% in seed usage, achieving the dual goals of precision agriculture and resource efficiency.

1.This model is equipped with an innovative rotary tillage ridging system. Its extended reinforced rotary blades enable deeper tillage and create a thick, loose soil layer, providing optimal conditions for onion plants to absorb nutrients and moisture, thereby achieving increased yield, improved efficiency, and high-quality crop production.

2.This towed eight-row pneumatic onion seeder offers integrated multi-function operation, capable of simultaneously completing multiple processes, including rotary tillage, ridging (leveling), drip tape laying, pneumatic seeding, real-time monitoring, and soil covering and compaction.

3.The ridging mechanism uses a rotary compression method to form well-defined, dense ridges that are resistant to collapse. The stainless steel ridging roller prevents soil adhesion and resists corrosion, ensuring consistent and durable ridging performance. The integrated design with the rotary tiller makes the equipment structure more compact, significantly enhancing maneuverability and operational adaptability.

4.The standard three-point hitch design allows for quick one-person hookup and detachment of the seeder without tools, reducing preparation time during field transfers and crop rotation, thereby effectively improving overall operational efficiency.

5.Equipped with a patented integrated electric blower, it features simple connection, stable suction, long service life, and minimal wear, and is compatible with tractors of all brands.

6.The detachable soil-collecting plate structure can be flexibly installed or removed according to the soil moisture and tillage depth requirements of different plots. It meets both the soil-throwing needs of deep tillage operations and the soil-conservation requirements of shallow tillage, fully supporting various working modes of the pneumatic seeder.

7. It is suitable for complex working conditions-the lengthened and thickened design enables it to cope with complex tillage conditions such as heavy clay soil and stony land, is not easy to be entangled or damaged by debris, and has more prominent adaptability and reliability under harsh working conditions compared with ordinary rotary tiller blades.

8.The profiling design has inherent elastic buffering characteristics, which can flexibly avoid obstacles such as stones and soil ridges, reduce rigid impact damage to the gantry and the connection parts of the whole machine, and extend the service life of the equipment.

9. Modular sowing unit design enhances multi-terrain adaptability, delivering superior seeding performance across sloping, rugged, and uneven terrain while effectively preventing hexagonal shaft fractures on uneven surfaces.

10.Terrain adaptability: Quickly conforms to undulating surfaces in hills/mountains, reducing skips/doubles and adapting to complex working conditions.Reduced failures: Prevents blockages of fertilizer tubes and soil heaps caused by component deviation, lowering failure rates and downtime for maintenance.

11. Row spacing, plant spacing, ridge height, and ridge width can all be customised to specific requirements.

12. Adopting a mechanical gear adjustment structure, it has a lower failure rate than the electronic adjustment method. The adjusted plant spacing is not easy to deviate during long-term operation, and can always maintain uniform and consistent seeding accuracy, providing stable support for the precise seeding of the air-suction seeder.

13. Saves high-quality seed costs: Retrieves residual seeds left in the air-suction system that fail to be sown, avoiding waste of expensive seeds such as hybrid and premium varieties, and significantly reducing planting input costs.

14.Precise seeding quantity control: Scraps off excess seeds adsorbed on the suction nozzle surface, ensuring only the rated number of seeds are adsorbed each time, avoiding reseeding and over-seeding, guaranteeing uniform plant spacing and improving crop growth consistency.

15. Real-time monitoring is integrated into every seeding unit, allowing seed intake to be observed via the in-cab display.

16. A roller assembly is fitted behind the seeding unit to adjust compaction intensity. An advanced soil-breaking device is also incorporated to prevent cementing of the seedbed in high-moisture soils, ensuring seeds receive adequate oxygen and moisture for optimal germination and growth.

17. A weed-clearing plough is positioned ahead of the seeding unit to effectively strip away weeds, facilitating seed placement.

Traditional seeders may just be a 'cost item,' while advanced pneumatic seeders have transformed into a 'value-creating engine.' They are not only performing the sowing process, but also simultaneously acting as:
- Resource optimizer :saving seeds, fertilizer, water, and fuel
- Quality controller :ensuring complete, uniform, and healthy seedlings
- Data collector :providing firsthand data from field operations
- Agronomy executor :accurately implementing scientific planting plans
- Future connector :providing interfaces for smart agriculture ecosystems

When fitted with an imported pressure gauge, the seed suction performance can be observed during operation.

Utilising a powder coating process, it is rust-proof and boasts a long service life.

1.Daily Maintenance (After Each Operation)
Complete the above "Post-Operation Cleaning."
Check and replenish grease or lubricating oil at lubrication points such as fan bearings, drive sprockets, and furrower arms.
Check tire pressure.
Quickly inspect for any new looseness or damage.
2. Periodic Maintenance (Every Season or After Every 100-150 Hours of Operation)
Deep cleaning and inspection: Perform a more thorough disassembly, cleaning, and inspection of the whole machine.
Key Component Inspection and Replacement:
Seed suction plates: Check if the suction holes have enlarged or become deformed due to wear. Severely worn plates are the main cause of double seeding or missed planting and must be replaced promptly.
Fan: Check fan blades for damage and bearings for looseness or unusual noise. If necessary, have them serviced or replaced by professionals.
Air tubes and seals: Check all air tube joints and air chamber seals for aging or leaks. Air leaks can directly lead to unstable negative pressure.
Wearing parts: Check furrower tips, press wheel surfaces, drive chains/belts, scraper boards, and other vulnerable parts. Replace immediately if wear exceeds limits.
Calibration: Calibrate seeding monitoring sensors and pressure sensors.
3. Long-Term Storage Maintenance (Post-Season or When Not in Use for Extended Periods)
Complete all cleaning and inspections.
Apply anti-rust oil to all exposed metal surfaces (such as furrowers and frames).
Lift tires off the ground and release all spring tension.
Disconnect the battery (if present).
Cover the machine with a dust cover and store it in a dry place.
