The cutting knife 28 is fixedly connected to one end of the rotating rod 27 and located inside the granulation box 12. The cutting knife 28 is located outside the granulation orifice plate 25.
[0029] Therefore, when it is necessary to produce compound fertilizers of different sizes and dimensions, the operator turns on the electric telescopic rod 21 to drive the U-shaped frame 22 to move toward the granulation box 12, and the movement of the U-shaped frame 22 drives the adjusting rod 23 and the rotating rod 27 to move.
