At the same time, the No. 1 vertical rod moves to the left and drives the U-shaped plate to move. The movement of the U-shaped plate causes the casting rod to cast in the direction close to the transmission shaft, so that the fertilizer is evenly distributed in the water tank, and the water and fertilizer are better dissolved. At the same time, the movement of the U-shaped plate drives the No. 2 cylindrical rod and the fan blades to rotate, so as to better disperse the fertilizer and prevent the fertilizer from piling up and being difficult to dissolve, thereby reducing the drip irrigation efficiency.
