The annular cooling box 11 can be fixed to the outer wall of the feed hopper 3 by bolts, and a plurality of cooling pipes 12 are provided at the bottom of the annular cooling box 11. When the cooling machine body 2 of this structure adds fertilizer to the inside through the feed hopper 3 for cooling, the stepper motor 5 can drive the rotating shaft 6 to rotate in an orderly manner by driving at the bottom of the arch frame 4. When the rotating shaft 6 rotates, the circular ring 7 and the plurality of dispersing blades 8 can also rotate in an orderly manner. When the fertilizer inside the feed hopper 3 falls into the inner wall of the circular ring 7, the stepper motor 5 can drive the rotating shaft 6 to rotate in an orderly manner. When the fertilizer is in a certain amount of time, it will contact with several groups of dispersing blades 8, so that the rotating dispersing blades 8 can disturb and disperse some of the clumping fertilizers, so that the fertilizers can be fed into the feed hopper 3 more evenly, avoiding the problem that the fertilizers cannot be fed evenly into the feed hopper 3 due to high temperature, which can easily cause blockage. In addition, cooling water can be added to the interior of the annular cooling box 11 and flow into each cooling pipe 12. The cooling pipe 12 can cool the feed hopper 3 to a certain extent, so as to realize the function of pre-cooling the fertilizers when feeding into the feed hopper 3, speed up the cooling speed of the fertilizers, and help improve production efficiency. Each group of dispersing blades 8 is provided with two and they are distributed up and down, and each corresponding side of the dispersing blades 8 is provided with a plurality of tooth openings 9.

A plurality of short blades 10 are arranged around the outer wall of the circular ring 7, and the top of the short blade 10 is in an inclined structure. When the circular ring 7 of this structure rotates, it will synchronously drive the plurality of short blades 10 to rotate and contact part of the fertilizer inside the feed hopper 3.

[0019] Working principle: When using the new drum cooler feeding structure, first insert the two clamping blocks 14 into the clamping interface 13 to quickly install the arch frame 4 inside the feed hopper 3. When the cooler body 2 adds fertilizer through the feed hopper 3 for cooling, start the stepper motor 5. When the stepper motor 5 is driven, it will drive the rotating shaft 6 to rotate in an orderly manner. When the rotating shaft 6 rotates, it can synchronously drive the ring 7 and several groups of dispersing blades 8 to rotate in an orderly manner. At this time, part of the fertilizer added inside the feed hopper 3 will fall into the ring 7 and contact with several groups of dispersing blades 8, and the fertilizer will contact the gap between each group of dispersing blades 8 when passing through it. The fertilizer will reach the tooth mouth 9, and part of the fertilizer will also come into contact with several short blades 10, so that the dispersing blade 8 can cooperate with the tooth mouth 9, and the short blade 10 can cooperate with the inner wall of the feed hopper 3 to disturb and disperse the fertilizer, so that the fertilizer can be more evenly fed into the cooler body 2 in the feed hopper 3. At the same time, the annular cooling box 11 can add cooling water through the water injection port at the top, and the cooling water added to the inside of the annular cooling box 11 will overflow into each cooling pipe 12. The cooling pipe 12 and the annular cooling box 11 can physically cool the feed hopper 3, and the fertilizer inside the feed hopper 3 can be indirectly pre-cooled, thereby completing a series of tasks.
