AI Technical Summary

Technical Problem

Existing seeds are prone to carry some impurities and broken particles when sowing, resulting in insufficient quantity when separating seeds by volume, affecting the planting effect.

Method used

A seeding mechanism for a seeding machine is designed, including a seeding frame, a quantitative conveying assembly and a screening assembly. A screening assembly is installed in the inclined section of the seed frame to remove impurities and broken particles from the seeds; the quantitative conveying assembly realizes the division and conveying of seeds according to a fixed volume through a partition plate and a motor-driven transverse column.

Benefits of technology

Through the screening of the screening assembly and the segmentation of the quantitative conveying assembly, impurities and broken particles in the seeds are effectively removed, ensuring that the seeds are divided according to a fixed volume, avoiding the problem of insufficient quantity, and improving the uniformity and efficiency of sowing.
