[0002] Currently, after livestock sperm is collected, sex-controlled frozen semen is used for artificial insemination and production of sex-controlled embryos to control the sex of born breeding animals. After differentiation, the sperm needs to be placed in test tubes and test tube racks, and then the test tubes and test tube racks are placed in a freezing preservation device for storage and preservation.

[0003] In the existing freezing storage device, when placing sperm test tubes and test tube racks, users usually manually place the test tube racks at a higher position from the bottom of liquid nitrogen, so that the sperm can gradually adapt to the low temperature environment.

As a result, the user needs to wear antifreeze measures for multiple times to manually operate, which reduces the protection for the user. Therefore, we propose a bovine sperm freezing storage device with easy-to-use functions, which is urgently needed to be developed. Utility Model Content

[0043] A working principle of a dairy cow sperm freezing and preservation device: the user first puts the sperm storage tube 67 into the test tube rack 66, and then starts the liquid nitrogen tank 4. The liquid nitrogen tank 4 gradually transfers the liquid nitrogen to the storage box 1 through the first transmission pipe 5 and the second transmission pipe 51, and freezes and stores the sperm storage tube 67. The height position of the sperm storage tube 67 can be adjusted before freezing, thereby avoiding the direct contact between the sperm storage tube 67 and the liquid nitrogen, and further preventing the sperm storage tube 67 from being damaged due to the direct contact. During the process, the height of the sperm storage tube 67 can be adjusted by the adjustment component 6, which improves the protection of the sperm storage tube 67. When the sperm storage tube 67 is taken out, the adjustment component 6 and the rotating component 7 can be used to cooperate to make the sperm storage tube 67 taken out one by one, and avoid the leakage of a large amount of cold air when taking it out, which is convenient for use.
