AI Technical Summary

Technical Problem

When existing seeders sow corn, the corn seeds are large in size and easy to break, which leads to some seeds being unable to germinate and cannot be discovered in time, and replanting is needed, which affects the sowing efficiency and crop yield.

Method used

A high-speed air-blowing precision seeder is designed, using an air-blowing circulation screening sowing mechanism to blow and transport corn seeds through high-speed airflow, and screen the weight difference between the complete seeds and the broken seeds to isolate the broken seeds. At the same time, an auxiliary support adjustment mechanism is set up to optimize the travel adjustment process of the seed machine, reduce the jitter of the seed assembly, and ensure the complete planting of seeds.

Benefits of technology

It effectively improves the sowing fluency and germination rate of corn seeds, reduces seed damage and replanting conditions, and improves the performance and crop yield of the seed machine.

Abstract

The present invention discloses a high-speed air-blowing precision seeder, which includes a horizontal frame of the seeder. In the middle of one side of the horizontal frame of the seeder, a connecting front frame is fixedly installed. In the middle of the top of the horizontal frame of the seeder, an installation top plate is fixedly connected. At one end of one side of the installation top plate, a power generation component is embedded and installed. In the middle of the other side of the installation top plate, a negative pressure fan component is embedded and installed. At the top of one end of the negative pressure fan component, a long air guide pipe is fixedly connected. At the edge of the top of the long air guide pipe, a protective top cover is clamped. The present invention effectively improves the smoothness of seeding of the seeder. Through the flexible transportation of corn seeds by high-speed air flow, it effectively prevents the phenomenon that the corn seeds are damaged due to mechanical shearing during the transportation process, ensures that the corn seeds can be completely planted into the field, improves the germination rate of the corn seeds after sowing, and improves the service performance of the seeder.
