AI Technical Summary
Traditional trenching and fertilization machinery cannot flexibly adjust the trenching depth and fertilizer discharge height, resulting in uneven fertilization and easy clogging, which affects crop absorption efficiency.
The synchronous lifting and lowering adjustment of the furrow opener and fertilizer discharge pipe is achieved by using a gear and rack linear lifting adjustment device and a cam-controlled bidirectional self-locking ratchet mechanism. It is also equipped with a dual-motor counter-pushing semi-circular disc linear vibration mechanism and an eccentric roller rotary high-frequency vibration module to prevent clogging.
It enables precise and continuous fertilization under different soil conditions, reduces fertilizer waste, improves crop yield and quality, and meets the needs of diverse agricultural scenarios.
