Air suction sowing machine

Qingdao Dashun Jingfeng Industry and Trade Co., Ltd. specializes in the R&D, production, and sale of agricultural machinery. For years, the company has focused on air-suction vegetable seeders as its flagship line, continually refining the technology. By combining mature manufacturing processes, rigorous quality control, and full after-sales support, the company provides efficient, durable, precise, and affordable seeding solutions to individual growers, agricultural cooperatives, and large-scale farms.

The pneumatic vegetable seeder adopts internationally advanced negative-pressure precision seeding technology, paired with a high-efficiency vacuum fan. Through accurate regulation of negative pressure, it is tailored for small, round, and granular vegetable seeds such as cabbage, radish, and tomato. The system achieves reliable single-seed pickup and precise drop into seed cells, eliminating missed, double, or misplaced seeds and greatly enhancing seed utilization. It suits large vegetable bases, family farms, cooperatives, and modern planting areas, performing consistently in open fields and greenhouse operations alike and boosting sowing speed several times over manual methods.

Uniform emergence is markedly improved, seed waste is sharply reduced, and subsequent thinning labor costs are lowered—helping users achieve intensive, efficient, and precise planting. The frame is built from high-strength steel with a rational structure, sturdy enough for plains, hills, greenhouses, and other complex terrains. Operation and maintenance are straightforward, requiring no professional technical background, making it a dependable tool in modern vegetable cultivation.

• By Number of Rows: Single-row and multi-row versions are available, with multi-row models customizable from 1 to 18 rows. 2–4 row models target small family farms, while 10–18 row models suit large-scale bases—covering requirements from individual growers to large farms.
• By Power Type: Tractor-mounted and self-propelled variants. Tractor-mounted models are compatible with mainstream hand-guided and four-wheel tractors, easy to assemble and disassemble, with strong mobility. Self-propelled models carry their own power system and require no external towing, ideal for scattered plots or environments where towing is impractical.
• By Applicable Crops: Dedicated models for carrots, onions, and leafy vegetables (lettuce, Chinese cabbage, spinach, etc.). Each features sowing discs and suction nozzles designed around the seed size and shape of the target crop, ensuring accuracy and alignment with agronomic requirements.
• By Functional Configuration: Pure sowing type and sowing-fertilizing integrated type. The pure sowing type focuses on precise seeding with a simple structure and easy operation. The integrated type performs sowing and fertilizing in one pass, reducing field work frequency and lowering labor input costs.

• High-precision sowing: Advanced air-absorption precision seeding and a high-stability negative-pressure control system deliver single-grain seeding accuracy above 98%, with an overall emergence rate of no less than 95%. The result is uniform, strong seedlings. Manual thinning workload drops significantly, labor costs fall, and a solid foundation is laid for high yield.
• Wide crop coverage: Suitable for carrot, onion, lettuce, spinach, coriander, cabbage, radish, celery, and other common vegetable seeds. Whether small spinach seeds, round onion seeds, carrot seeds, or pelletized seeds, the machine delivers precise placement to meet diverse planting needs.
• Labor and seed savings: Compared with manual sowing, operation speed increases 5 to 10 times, and a single unit can complete dozens of acres per day. Seed utilization rises by more than 30%, greatly reducing seed waste, cutting labor and seed costs, and helping users reduce costs and increase efficiency.
• Sturdy and durable: The whole machine uses thickened high-quality steel with a strong, wear-resistant frame. Key components—suction nozzles, seeding discs, bearings—receive wear-resistant, anti-rust, and anti-corrosion treatment, withstanding harsh field conditions. The structure is solid, daily maintenance is easy, the failure rate is extremely low, and the design service life is 8 to 10 years.
• Easy to operate: A user-friendly layout, clear control panel, and well-marked labels and instructions mean even novices can master it quickly after brief learning. The entire process—from startup and parameter adjustment to shutdown—is convenient, reducing operator burden.
• Flexible functional combinations: The machine can be matched with fertilizer spreaders, soil covering devices, press wheels, drip irrigation belt layers, and other components to achieve one-pass sowing, fertilizing, soil covering, and compaction—even simultaneous drip tape laying—reducing field operations and improving efficiency.

• Packaging: Standard export plywood crates or simple iron frame packaging, selected by equipment size and weight. Interiors receive moisture-proofing, shock absorption, and collision protection to ensure perfect arrival.
• Logistics: Sea, land, and air transport are supported, chosen based on customer requirements, delivery schedule, and budget. Equipment can be delivered to the designated port, warehouse, or final destination, with full tracking and timely updates.

Detailed installation manuals and operation videos are provided in Chinese and English, with clear steps and intuitive guidance to help customers complete installation quickly. One-on-one remote video guidance is also available, allowing real-time problem resolution and quick commissioning with minimal downtime.

Traditional sowing often wastes significant seed due to uneven placement and over-seeding. Our advanced air suction system improves seed efficiency by placing each seed accurately and individually, reducing unnecessary consumption and directly lowering planting costs. Depending on crop type, seed savings can reach substantial levels.

The company has long supplied a full range of original factory parts for vacuum vegetable seeders, including seed plates, suction nozzles, bearings, belts, gears, press wheels, soil covering devices, negative pressure fans, solenoid valves, sealing rings, and more. All parts undergo strict quality inspection and are perfectly compatible with the equipment, with replacements not affecting overall operation. A dedicated parts warehouse with standardized management ensures timely supply, and prompt shipments via express or logistics enable fast replacement of damaged parts, reducing downtime. The company also offers parts wholesale services with favorable prices for large farms, distributors, and bulk buyers.

• What is the machine material? The frame is made of high-strength steel with durable anti-rust treatment.
• How is the seed released? When the seed plate rotates to the discharge position, vacuum pressure stops and seeds drop accurately into the furrow.
• What is included in one operation? Furrowing, seed metering, precision dropping, covering soil, and pressing.
• Do you provide spare parts? Yes, available for long-term supply.
• Do you provide after-sales support? Yes. We offer installation guidance, operation videos, technical consultation, and online service.
