Rows spacing can be adjusted by replaced seed suction disc - details see: https://www.machineto.com/2byqf-4h-pneumatic-precise-corn-fertilization-seeder-10187783

Advantage and Character:

1. Vacuum precise planter can realize precise sowing single seed. One hole only one seed, no need to thin out seedling. Precise sowing, seedling is even and sturdy.

Rows spacing can be adjusted by replaced seed suction disc. 2BYQFH-6 is mainly used in sowing corn and bean. Plant spacing can be changed by adjusting the chain transmission system or changing the seed suction disc.

2. We installed seed suction-disc with 16 holes, and do strict adjusting for seed cleaner, so it is no need to do new adjusting by customers, in case of making empty hole and affecting the single seed rate.

3. Seed suction-disc with 16 holes can realize different plant spacing, such as 200, 240, 250, 310 mm and so on, by changing the transmission radio.

4. Use good seeds, whose germination rate should be higher than 95%, and do coating or presoaking in pesticide for improve the seeds quality, then the seeds should have good fluidity, and have no adhesive. Forbid using powder mix seeds in case of making loss of potency of pesticide and plugging up seeds suction holes.

5. Sow fertilizer deeply, make sure that the fertilizer should be deeper than seeds for 40 mm.

6. The parallel linkage contour may ensure the planting mechanism can make contour either on flat ,valley or sloping land so the planting depth is consistent.(2BYQFH-6 and 2BYQFH-4A)
