Installation cylinders 13 are fixedly installed in the three installation slots 12. Fans 14 are arranged in the three installation cylinders 13.

At the same time, the wind generated by the fans 14 can make the fertilizer stay on the conveying plate 3 for a longer time, thereby improving the drying effect.

[0027] Working principle: When in use, pour the finished fertilizer into the processing box 1 through the feed inlet 101. The fertilizer falls on the granulation plate 2. Then start the first motor 53. The output shaft of the first motor 53 drives the rotating shaft 52 to rotate, thereby driving the T-shaped rod 54 sleeved on the rotating shaft 52 to continuously move up and down, and then driving the pressing plate 55 inside the processing box 1 to continuously move up and down, so that the pressing plate 55 squeezes the fertilizer on the granulation plate 2. The squeezed fertilizer forms a strip shape through the granulation holes 21. At this time, start the second motor 61. The output shaft of the second motor 61 drives the rotating rod 62 to rotate. The rotation of the rotating rod 62 drives the driving bevel gear 67 to rotate. Since the driving bevel gear 67 meshes with the driven bevel gear 68, when the driving bevel gear 67 rotates, it drives the driven bevel gear 68 to rotate synchronously, thereby driving the drive shaft 65 to rotate, and then driving the blade 66 to continuously rotate, so that the blade 66 shears the fertilizer extruded from the granulation holes 21, cutting the strip-shaped fertilizer into granular shape. The cut granular fertilizer falls onto the conveying plate 3 under the action of gravity. At this time, start the heating pipe 4 and the third motor 71. The heat generated by the heating pipe 4 continuously rises and passes through the small holes opened on the conveying plate 3, so as to contact the fertilizer and dry it. The output shaft of the third motor 71 drives the rotating plate 72 to rotate. The rotation of the rotating plate 72 drives the convex block 73 arranged on its upper surface to rotate synchronously. When the arc surface of the convex block 73 contacts the pulley 75, it will push the pulley 75 to move upward for a certain distance, thereby pushing the support rod 74 and the conveying plate 3 to move upward synchronously. When the pulley 75 passes the convex block 73, due to the gravity of the conveying plate 3, the support rod 74 and the pulley 75 itself, the conveying plate 3 moves downward. As the rotating plate 72 continuously rotates, the conveying plate 3 continuously moves up and down, so as to continuously convey the granular fertilizer on its top towards the discharge port 102.
