Product Advantages
- 1 The imported air suction seed discharging device has high sowing accuracy and strong working reliability, and its seed plate is adjustable, which makes it suitable for different grains.
- 2 The angle of the seed discharging tube is reasonable, which realizes precision hole seeding.
- 3 It has a four-link profiling structure and can adjust the ground pressure by means of a spring, which enables the same depth of seeding.
- 4 The fertilizer and sowing trencher is made of boron steel and bow plate, and the row spacing is adjusted in a wide range, which can realize flat cultivation and ridge cultivation.
- 5 It adopts imported high speed and large air volume fan, which can meet the requirements of 24 lines of single air volume at most.
- 6 Its enlarged fertilizer box improves sowing efficiency and reduces fattening time. The fertilizer discharger impeller is made of imported rubber with long life and corrosion resistance. It can easily realize the control requirement of fertilizer quantity by adjusting the handle.
- 7 Its seed discharging monitor can detect missing seeds at the first time, which will greatly improve work efficiency.
- 8 The plant spacing can be adjusted through the gearbox and adjusting the sprocket.
- 9 The suppression intensity and soil cover angle can be adjusted by quickly adjusting the handle to meet the agronomic requirements of different lands and crops.
- 10 The tire drive can provide reliable power even in the stubble ground, and the universal transmission shaft is well sealed and has the function of self-lubricating and maintenance-free.
- 11 Fertilization method: double disc and leg lifting. The traction frame and marking device are optional.
- 12 The design of cast iron compaction body with multi position adjustment can better maintain soil moisture and improve seedling emergence rate.

Frequently Asked Questions
-
Q What crops are compatible with the 2BQ series pneumatic precision seeder?The 2BQ series pneumatic precision seeder is designed for a wide range of grain crops. Its adjustable seed plate allows it to accommodate different grain sizes and types, making it suitable for corn, soybeans, sunflowers, and other large-grain crops that require precision hole seeding.
-
Q How do I choose the right model — 2BQ-4, 2BQ-6, 2BQ-8, 2BQ-10, or 2BQ-12?The model number indicates the number of working lines (e.g., 2BQ-4 has 4 lines, 2BQ-12 has 12 lines). Selection should be based on your tractor's power output, field size, and desired working efficiency. For example, the 2BQ-4 requires 66.1–88.23 kW, while the 2BQ-12 requires ≥176.4 kW. Larger models offer higher hourly production rates.
-
Q How is the seeding depth controlled and adjusted?The seeder features a four-link profiling structure with spring-adjustable ground pressure, ensuring consistent seeding depth across uneven terrain. The trencher depth adjustment range is 0–60 mm for seeding and 0–100 mm for fertilization, adjustable via the ground wheel height mechanism (0–200 mm for 2BQ-4; 0–160 mm for other models).
-
Q Can the row spacing be customized for different planting requirements?Yes. The row spacing is adjustable across a wide range — from 400 mm to 750 mm depending on the model — allowing the seeder to meet various agronomic requirements for both flat cultivation and ridge cultivation. The fertilizer and sowing trencher is made of boron steel and bow plate to support this flexibility.
-
Q What is the fan system used for, and what are its specifications?The seeder uses an imported high-speed, large-volume centrifugal fan with a 400 mm impeller diameter to generate the air pressure required for the pneumatic seed metering system. A single fan unit can support up to 24 working lines, ensuring efficient and reliable seed delivery across all models in the 2BQ series.
-
Q Does the seeder work effectively in stubble fields, and what maintenance is required?Yes. The 2BQ series is equipped with stubble breaking and ridge cleaning working parts (shovel type for 2BQ-4; straight knife tool for 2BQ-6 to 2BQ-12) to handle residue-covered fields. The universal transmission shaft is well sealed with a self-lubricating, maintenance-free design, and the fertilizer discharger impeller is made of imported rubber for long service life and corrosion resistance, minimizing routine maintenance needs.
