AI Technical Summary

Technical Problem

Existing multi-row wheat and corn planters suffer from inconvenient row spacing adjustment, low precision, complex adjustment process, and insufficient stability, making it difficult to meet the planting needs of different fields.

Method used

A multi-row spacing self-adjusting seeder was designed. The adjustment components include a limit frame, a limit groove, a moving groove, a moving block, an adjusting bolt, a lifting block, a drive rod, a rotating rod, a drag-reducing wheel, and a mounting platform. The rotating rod drives the drag-reducing wheel to roll in the limit groove, thereby achieving precise adjustment of the spacing between the seeding units and reducing frictional resistance.

Benefits of technology

It enables flexible and precise adjustment and stable operation of sowing row spacing, reduces operational complexity and labor intensity, and improves sowing uniformity and efficiency.
