[0028] Working principle:

[0029] The fertilizer raw materials requiring cooling are fed into the mixing tank 1 through the feed inlet 9. The fertilizer raw materials are granular and mainly contain elements such as nitrogen, phosphorus, and potassium. The fertilizer raw materials fall onto the ventilation plate 7, which prevents them from falling further. The cooler 15, water pump 14, and fan 11 are started. The cooler 15 cools the water inside the water tank 16, and then the water pump 14 draws out the cooled water from the water tank 16 (the water tank 16 is first filled with water; a valve can be installed on the top of the water tank 16, but it is not shown in the figure). The cooling water then flows back through the pipe 8 to the mixing tank 1. The interior of the water tank 16 is cooled again through a circulating cooling system (the water tank 16 and the mixing tank 1 are in different spaces during use to avoid the heat emitted by the cooler 15 affecting the operation of the device). The air blown out by the fan 11 is cooled by the pipe 8 and then by the ventilation plate 7 to cool the fertilizer raw materials inside the mixing tank 1. The air inside the mixing tank 1 is discharged through the feed inlet 9. The filter screen 12 can prevent dust in the air from entering the fan 11. The staff needs to clean the filter screen 12 regularly (the filter screen 12 is detachable).

[0030] Stirring process:

[0031] Connect the external power supply to the first servo motor 5, start the first servo motor 5 to drive the stirring rod 6 to rotate, and stir the fertilizer raw materials inside the mixing box 1. Then connect the external power supply to the second servo motor 402, start the second servo motor 402 to drive the rotating rod 403 to rotate. The rotation of the rotating rod 403 causes the cylinder 404 to slide inside the straight rod 405. The movement of the cylinder 404 causes the straight rod 405 to swing around the right end (e.g., Figure 5 The straight rod 405 swings, causing the sliding rod 406 to move. The movement of the sliding rod 406 causes the slider 3 to move. The slider 3 is slidably connected to the first outer shell 2 through the sliding rod 406 and the protrusion on the left side, so that the slider 3 can only move up and down. The movement of the slider 3 causes the first servo motor 5 and the stirring rod 6 to move. The up and down movement of the stirring rod 6 can improve the uniformity of stirring and improve the cooling efficiency.

[0032] After cooling is complete, turn off the first servo motor 5, the second servo motor 402, the fan 11 and the water pump 14, and then open the sliding door 13 to take out the cooled fertilizer raw materials inside the mixing tank 1. There is a sealing strip and a buckle structure between the sliding door 13 and the mixing tank 1, which can maintain a sealed state when closed.

[0033] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
