AI Technical Summary

Technical Problem

Existing seeders have problems such as incomplete seed cleaning, easy congestion of seed flow, delayed or missed seeding, and uneven seeding in multiple channels, especially when multiple channels are used for coordinated seeding.

Method used

A multi-row seeder horizontal disc precision seeder was designed. It adopts a three-stage seed cleaning mechanism to clean seeds in stages along the rotation direction of the seed metering disc, and is equipped with a forced seed pushing mechanism. Combined with furrowing and soil covering and roller devices, it realizes seed flow density control and seeding accuracy. It adopts a three-row seeder with a three-channel layout.

Benefits of technology

It significantly improves sowing precision and efficiency, reduces impurity residue rate, reduces missed sowing rate, reduces soil compaction rate, and improves operational efficiency, making it suitable for large-scale planting of high value-added crops.
