[0026] like Figure 1and Figure 2 As shown, the present application provides a feed pelletizing cooling device, including a cooling bin 1, a feed inlet 2 is provided at the top of the cooling bin 1, a discharge pipe 3 is connected to the bottom of the cooling bin 1, a discharge valve 4 is provided on the discharge pipe 3, a stirring cooling component 5 is provided in the cooling bin 1, and a driving component 6 for driving the stirring cooling component 5 to rotate is provided at the top of the cooling bin 1; the stirring cooling component 5 includes an air duct 51, a hollow rotating shaft 52 and a plurality of hollow stirring rods 53, the upper part of the hollow rotating shaft 52 is rotatably connected to the top of the cooling bin 1, the upper end of the hollow rotating shaft 52 extends to the outside of the cooling bin 1 and is movably sealed and connected to the air duct 51, and the plurality of hollow stirring rods 53 are evenly fixed on the cooling bin 1. On the hollow rotating shaft 52, the interior of the hollow stirring rod 53 is connected with the interior of the hollow rotating shaft 52, and a plurality of air outlet holes are evenly arranged on the hollow stirring rod 53. When in use, the feed pellets to be cooled are put in through the feed inlet 2, and then cold air is input into the hollow rotating shaft 52 through the air duct 51. The cold air flows into the hollow stirring rod 53 and then flows into the cooling bin 1 from the air outlet holes on the hollow stirring rod 53. At the same time, the driving component 6 drives the stirring and cooling component 5 to rotate, so that the feed in the cooling bin 1 is stirred and cold air is blown in for cooling. The cooled feed pellets in the cooling bin 1 can be discharged by opening the discharge valve 4. The structure is simple and the cooling efficiency is effectively improved.

[0027] like Figure 1 and Figure 2 As shown, the driving assembly 6 includes a driving motor 61, a first bevel gear 62 and a second bevel gear 63. The driving motor 61 is fixedly mounted on the top of the cooling bin 1. The first bevel gear 62 is fixedly connected to the output shaft of the driving motor 61. The second bevel gear 63 is fixedly mounted on the hollow rotating shaft 52. The first bevel gear 62 is meshed with the second bevel gear 63. The driving motor 61 drives the first bevel gear 62 to rotate, thereby driving the second bevel gear 63 to rotate, thereby causing the hollow rotating shaft 5253 to rotate. The rotation of the hollow rotating shaft 52 drives the hollow stirring rod 53 to rotate, thereby achieving stirring of the feed pellets in the cooling bin 1.

[0028] like Figure 1 and Figure 2 As shown, a plurality of ventilation holes 7 are evenly arranged on the upper circumference of the cooling bin 1, and heat dissipation and ventilation are carried out through the ventilation holes 7 to maintain the gas flow in the cooling bin 1 and improve the heat dissipation effect. Specifically, the cold air blown into the cooling bin 1 through the air outlet carries the heat in the feed pellets to be cooled and flows out from the ventilation holes 7.

[0029] like Figure 2 As shown, a bearing 8 is embedded in the top of the cooling bin 1, and the hollow shaft 52 is rotatably connected to the top of the cooling bin 1 through the bearing 8. The setting of the middle bearing 8 makes the hollow shaft 52 rotate more smoothly. It can also avoid the wear of the hollow shaft 52 due to direct contact with the top of the cooling bin 1, thereby extending the service life.

[0030] like Figure 2 As shown, a scraper 9 is fixedly provided at one end of the hollow stirring rod 53 away from the hollow rotating shaft 52. When the interior of the cooling bin 1 needs to be cleaned, water is input from the feed inlet 2, and the driving component 6 drives the stirring and cooling component 5 to rotate, so that the scraper 9 rotates to scrape and wash the inner wall of the cooling bin 1, and then the sewage in the cooling bin 1 is discharged by opening the discharge valve 4 to improve the cleaning effect.

[0031] like Figure 1 and Figure 2 As shown, a movable sealing joint 10 is provided at the upper end of the hollow rotating shaft 52, and the air duct 51 is movably and sealedly connected to the hollow rotating shaft 52 via the movable sealing joint 10. The movable sealing joint 10 belongs to the prior art, and its structure is not described in detail here. The movable sealing joint 10 ensures that the hollow rotating shaft 52 is movably connected to the air duct 51 to avoid movement interference.

[0032] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
