[0020] A second rotary joint 31 is provided between the connecting plate 13 and the second roller cutter 3 , and the second roller cutter 3 is fixedly mounted on the connecting plate 13 via the second rotary joint 31 .

[0021] Both ends of the auxiliary skate 4 are covered with protective covers 42 , and the fixing plate 43 is provided with screw holes, which are configured as long holes.

[0022] The first hob 2 and the second hob 3 are both provided with a plurality of blades, and the plurality of blades are evenly distributed on the first hob 2 and the second hob 3, respectively, and each of the blades is arranged parallel to each other.

[0023] The main shaft 1, the first roller blade 2, the second roller blade 3, the auxiliary roller blade 4, the inner cylinder 6 and the outer cylinder 5 are all made of stainless steel 316L material, and the protective cover 42 is made of rubber material.

[0024] The specific implementation method is as follows: when it is used to make flake ice, the main shaft 1 and the components on the main shaft are installed as shown in the figure, and the first roller 2 is attached to the outer surface of the inner cylinder 6 and the second roller 3 is attached to the inner surface of the outer cylinder 5. A water outlet 11 is set at the top of the main shaft 1, and water is injected into the main shaft so that water can seep out from the water outlet 11. Two sprinkler pipes are led out from the water outlet 11, and the water outlet ends of the sprinkler pipes are respectively set at the upper end of the outer surface of the inner cylinder 6 and the upper end of the inner surface of the outer cylinder 5. After sprinkling water, water freezes on the outer surface of the inner cylinder 6 and the inner surface of the outer cylinder 5.

This embodiment solves the problem in the prior art that the seawater flake ice machine often has only one cylinder body matching one roller for scraping ice, resulting in slow ice scraping efficiency.
