AI Technical Summary

Technical Problem

While existing seed counting devices can adjust the seed discharge rate according to preset parameters and changes in field conditions, they cannot accurately distinguish the specific number of seeds actually discharged each time, resulting in seed quantity errors and affecting the consistency of sowing and the final growth density of crops.

Method used

The overpressure generated by the compressed air fan causes the seeds to adhere to the drilled holes on the seeding disc. Excess seeds are scraped off by a scraper, and the number of seeds is counted by an optical sensor. The controller adjusts the scraper to achieve real-time automatic adjustment of the seed quantity.

Benefits of technology

It enables precise control over the amount of seeds released each time, improving sowing consistency and crop growth density.
