The transmission motor 1 is fixed on the motor mounting disc 2, the motor mounting disc 2 is fixed on the upper cover plate 4, and the motor transmission shaft 3 of the transmission motor 1 penetrates through the upper cover plate 4 to be connected with the upper end of the main shaft 5. The main shaft 5 is provided with a helical blade 6, the lower end of the main shaft 5 is embedded into a bearing position 18 at the center of the lower mounting disc 15 through a rotary cutting sleeve 16 and is positioned at the central axis position of the inner barrel 8.

The inner barrel 8 is cylindrical, separation water holes 9 with micron-level apertures are uniformly distributed on the cylindrical surface, the outer edge of the upper end protrudes outwards to form an ice sand table 7, and the lower end is an ice slurry inlet 10. An outer barrel 13 is arranged outside the inner barrel 8, the lower end of the outer barrel 13 is connected with a lower mounting disc 15, and the upper end of the outer barrel is connected with the ice and sand collecting barrel 12 and stretches out a small section. The outer edge of the upper end of the ice and sand collecting barrel 12 protrudes outwards to form a fixing flange 11, and the upper cover plate 4 is matched with the fixing flange 11 to be used for sealing the ice and sand collecting barrel 12 and play roles in fixed connection and sealing.

The ice sand table 7 at the upper end of the inner barrel 8 is buckled at the upper end of the outer barrel 13, the spiral blade 6 extends out of a small section of the upper end of the inner barrel 8, the ice sand collecting barrel 12 is provided with an ice sand outlet 14 extending downwards in the area close to the barrel wall, and an ice sand baffle 17 extending upwards is arranged at one side edge of the ice sand outlet 14. Thus, the ice crystals carried out by the helical blade 6 fall to the bottom surface of the ice and sand collecting barrel 12 through the ice and sand disc 7 and enter the ice and sand outlet 14 under the blocking action of the ice and sand baffle 17.
