This utility model discloses a drip irrigation device for agricultural irrigation, relating to the field of drip irrigation technology. It includes a water delivery pipe and an irrigation mechanism. Several connecting blocks are fixedly connected to the outer wall of the water delivery pipe. During the movement of the connecting plate, the device causes inclined plate one to contact inclined plate two.
