AI Technical Summary

Technical Problem

Existing corn planting machines with plastic film have problems with insufficient precision and stability during seed dispensing and plastic film damage, making it difficult to control the seeding rate and affecting the efficiency and quality of corn planting.

Method used

The planting plate structure, which uses encoder-controlled feeding rollers and eccentric wheel drive, ensures accurate seed placement and stable puncture of the mulch film. The guide plate and transparent semi-circular plate prevent seed leakage, and the slider and groove design ensures smooth movement, achieving accurate sowing and resetting.

Benefits of technology

This method enables the orderly and precise placement and sowing of corn seeds, improving sowing efficiency and quality, reducing seed spillage and waste, and minimizing manual labor intensity, while ensuring precise and controllable sowing quantity.
