AI Technical Summary

Technical Problem

Existing tillage devices for grain planting cannot detect changes in soil resistance in real time, causing the plowshare to shift vertically due to sudden changes in soil resistance during operation, affecting the consistency of tillage depth and operational efficiency.

Method used

The system employs a hydraulically driven arc-shaped plate structure, which maintains the horizontal position of the arc-shaped plate through a limiting rod. Combined with a rotating block and a limiting block, it enables real-time adjustment of the plow head depth. It is also equipped with a spreading mechanism and a water tank system to ensure uniform sowing of seeds or fertilizers and spraying of the soil.

Benefits of technology

It achieves precise control of plow depth, ensures consistent soil turning depth, improves soil turning quality and work efficiency, and also enables uniform sowing of seeds or fertilizers and effective soil spraying.
