AI Technical Summary
Traditional farmland irrigation and fertilization methods are separate, resulting in low water and fertilizer utilization, soil compaction, environmental pollution, and high labor intensity. Existing integrated water and fertilizer devices have loose structures, low integration, insufficient mixing efficiency and uniformity, and are at risk of sealing failure.
Design an integrated water and fertilizer irrigation device, including a base frame, fertilizer tank, fertilizer mixing tank, water supply pump, fertilizer proportioning pump, irrigation pump and control system. It uses Venturi nozzles to achieve water and fertilizer mixing and combines PLC controller and sensors for automated management.
It improves equipment integration, reduces floor space, achieves uniform water and fertilizer mixing, reduces energy consumption, realizes automated fertilization, and improves the uniformity and timeliness of fertilization.
