Products Description
In a single pass, the machine can complete two ridges, four rows of rotary tilling, ridge formation, pneumatic seeding, and soil covering. The ridges utilize pneumatic suction-type single-seed precision seeding technology, equipped with a proprietary electric blower, an all-aluminum seeding unit, and imported suction cups and seals to ensure that only one seed is sown into each seed hole, without damage or missed seeds. Additionally, it features hand-crank seeding depth adjustment, removable tires, and a seed recovery system, allowing it to adapt to various field conditions and effectively improve the uniformity of carrot emergence and market yield.

Core Functional Modules
The pneumatic suction precision seeding system uses imported suction cups in conjunction with a proprietary electric blower to achieve precise seeding of one seed per hole, ensuring no missed seeds, no seed damage, and no double seeding.
The integrated single-pass operation combines rotary tilling, standardized ridge formation, drip tape laying, pneumatic suction seeding, soil covering, and compaction into a single pass.
The height-adjustable system supports customizable ridge widths and row spacing. It enables precise adjustment of plant spacing via a spacing adjustment box and is equipped with a hand-crank depth adjustment function (adjustment range: 0 to 2 centimeters) to accommodate various crops and agronomic requirements.
The terrain-adaptive contour adjustment system features an independent four-bar linkage mechanism and individual shock absorbers for each row, maintaining a constant seeding depth on uneven terrain to ensure uniform seedling emergence.
Stable Air Pressure System uses an independent high power turbine fan to maintain stable negative pressure regardless of tractor speed or field conditions, ensuring no missed seeding.
Modular Maintenance Design features independently arranged seed metering units, fan, and transmission for easy disassembly, cleaning, and parts replacement, resulting in low maintenance costs.

Working Principle
Tractor PTO drives fan to generate stable negative pressure
Seed plate picks up seeds one by one, releases into furrow at drop zone
Simultaneously completes: rototilling → ridging → drip tape laying → covering → pressing
Result: one pass, straight ridges, even spacing, consistent depth, one seed per hole
*Comparison with manual sowing: manual requires 2–3 persons/day per mu; this machine: 1 person/day for 50 mu*
Quality Assurance System
Process Inspection: During machining and final assembly, core components undergo periodic dimensional and fit inspections to proactively mitigate the risks of assembly deviations and operational failures.
Factory Verification: Before shipment, every seeder must pass tests verifying the stability of the vacuum system, the responsiveness of the actuators, and the overall system coordination to ensure it is ready for immediate use upon arrival at the field.
Batch Traceability: All major components are assigned unique production batch numbers, enabling full-process quality data traceability from raw material intake to finished product delivery.
Usage Effects & Benefits
Uniform emergence: no thinning needed, no overcrowding or gaps
Significant seed savings: 30%–50% less waste
Drastically reduced labor: single-person operation, eliminates thinning entirely
Comparison with manual sowing:
| Comparison | Manual Sowing | This Seeder |
|---|---|---|
| Efficiency | 0.5 mu/person/day | 50 mu/person/day |
| Emergence rate | 60–70% | ≥95% |
| Thinning required | Yes | None |
| Spacing consistency | Poor | Precise and uniform |
FAQ
Q: How does an air-suction seeder work?
A: An air-suction seeder uses a negative-pressure airflow to pick up seeds one by one and then precisely deposit them into each seed hole. Its greatest advantage is that it enables precision seeding-one seed per hole-thereby greatly reducing or even completely eliminating the need for manual thinning later on.
Q: For which crops is a pneumatic seed drill suitable?
A: It has a very wide range of applications, covering not only common vegetables such as radishes, Chinese cabbage, spinach, and sugar beets, but also medicinal herbs such as Atractylodes, Platycodon, and Scutellaria.
Q: What are the key precautions when operating a pneumatic seed drill?
A:If the seed drill must be temporarily stopped during operation, it should be immediately raised off the ground. When lowering it again, the tractor should move slowly to avoid component damage caused by sudden impacts. Additionally, it is strictly prohibited to reverse or make sharp turns while the seeder is lowered, to prevent damage to the seed dispenser and furrow-opening components.
Q: To which countries and regions does Qingdao Dashun Jingfeng export its products?
A: Our products are not only popular in many major agricultural production areas within China but are also exported to overseas markets such as Canada, Russia, and Australia.
