AI Technical Summary

Technical Problem

During the sowing operation of the existing needle-suction seeder, the seeds in the seed tray are not sufficiently sucked, resulting in the inability to perform the sowing operation normally, especially the seeds in the seed tray move slowly and the gap recovers slowly.

Method used

A seeder with a seed disc sweeping function is designed, which includes a conveying component, a punching component, a sowing component and a seed delivery component. The seed sweeping component can quickly restore the gaps created after the seeds are sucked out, ensuring that sufficient seeds are sucked in each time and that the sowing operation proceeds normally.

Benefits of technology

The rapid recovery of seed gaps in the seed tray is achieved, ensuring sufficient seeds are absorbed each time, and improving the automation and efficiency of the sowing operation.
