AI Technical Summary
Traditional planting site positioning and pitting devices require manual operation, which is labor-intensive and inefficient, making it difficult to efficiently plant soybeans and flue-cured tobacco.
Design a direct seeding tool for flue-cured tobacco-soybean intercropping with adjustable spacing, including a ridging machine, a turntable, and a pressing rod. The pressing rod on the turntable presses planting holes into the soil, and the planting point positioning is automatically achieved by combining the adjusting screw and the support frame.
It has achieved automated planting point positioning, improved planting efficiency, reduced manual operation, adapted to the growth needs of different crops, and met the planting requirements of flue-cured tobacco and soybeans.
