[0024] At the same time, a limited position through hole is provided inside the fixed base 1 at the ice blowing shaft 3 , and a bearing seat 7 is provided outside the ice blowing shaft 3 in the limited position through hole.

[0025] Meanwhile, a through hole is provided in the ice blowing shaft base 6 at the ice blowing shaft 3 , and a through hole 62 is provided in the ice blowing shaft base 6 at the middle of the bottom of the through hole and in the corresponding first cavity 64 and second cavity 65 .

[0026] In addition, a driving sprocket 5 is connected to one side of the ice blowing shaft 3 , and a plurality of radial grooves 31 are formed at equal distances on the outside of the ice blowing shaft 3 .

[0027] Furthermore, a first flow opening is opened in the fixed base 1 between the front cavity 12 and the air inlet pipe 2 , and a second flow opening is opened in the fixed base 1 between the rear cavity 13 and the blow-out pipe 4 .

[0028] At the same time, the bottoms of both sides of the fixed base 1 are installed with extended convex plates, and the tops of the extended convex plates are provided with a plurality of mounting holes at equal distances.

[0029] In addition, third flow openings are provided on both sides of the ice blowing shaft base 6 at the first flow opening and the second flow opening.

[0030] In this embodiment, the ice-blowing shaft base 6 is nested in the fixed base 1 so that an interference fit is achieved between the ice-blowing shaft base 6 and the fixed base 1 to achieve static sealing.

[0031] When the ice-blowing shaft 3 is stationary, the front cavity 12 and the rear cavity 13 of the fixed base 1 are divided into two independent cavities.
