Description

Technical Field

[0001] The utility model relates to the technical field of semen freezing, in particular to a simple freezing device for livestock semen. Background Art

[0002] With the development of biotechnology, artificial insemination and embryo transfer technologies have been widely used in livestock breeding. The biggest advantage of frozen semen is that it can be preserved for a long time, so that the use of semen is not limited by time, region, or the life span of male animals, and it can effectively protect precious germplasm resources. At present, artificial insemination is generally used for the breeding of livestock such as cattle, horses, and sheep in animal husbandry, and the fresh semen collected has defects such as short storage time and inconvenient transportation. In the existing technology, semen freezers can be used to freeze animal semen, but ranches are usually built in the wild away from human habitation, and transportation is relatively inconvenient. Semen freezers are large in size and difficult to transport to the semen collection site. In addition, semen freezers are expensive and difficult to repair and maintain, and their electricity consumption is high, and the equipment cost and maintenance cost are relatively high.

[0003] Therefore, for greater convenience, on-site staff at ranches typically use foam boxes to freeze semen. However, these boxes are easily damaged, can only freeze a small amount of semen at a time, and waste a lot of liquid nitrogen. To address these issues, the present invention provides a simple livestock semen freezing device that has the advantages of low cost, simple installation, ease of use, portability, easy parts repair and replacement, and savings in liquid nitrogen.

[0038] A simple freezing device for livestock semen, comprising:

[0039] The shell 1 is a semi-enclosed rectangular parallelepiped with an open top, and an insulation layer 2 is fixed to the inner wall of the shell 1. The interior of the shell 1 is used to hold liquid nitrogen and store semen tubes;

[0040] A pair of baffles 3, each of the baffles 3 is installed on the side of the insulation layer 2 away from the shell 1, and a first circular hole 31 is opened in the middle of each baffle 3;

[0041] The upper cover 4 has U-shaped rubber strips 41 fixedly connected to the bottom and both sides of the upper cover 4. The upper cover 4 is used in conjunction with the baffles 3. The width of the upper cover 4 is the same as the width between the two baffles 3. After the upper cover 4 is closed, a closed space can be formed inside the housing 1 to reduce the loss of liquid nitrogen.

[0042] A fumigation rack 9 includes a pair of support plates 91 connected by a plurality of arc-shaped racks 92 arranged in parallel in a horizontal direction. The upper side of the arc-shaped racks 92 is evenly provided with first arc-shaped teeth 921, and the lower side of the arc-shaped racks 92 is evenly provided with second arc-shaped teeth 922 for placing frozen semen tubes.

[0043] Each of the support plates 91 has a third circular hole 911 in the middle, and is connected to a height adjustment assembly through the third circular hole 911. Each of the height adjustment assemblies is connected to the housing 1 for adjusting the vertical height of the semen frozen straw tube. Furthermore, two height adjustment assemblies are arranged on both sides of the upper cover 4, and each height adjustment assembly includes: a U-shaped bracket 5, an annular column 6, a support rod 7, a top screw 8 and a circular baffle 10. The U-shaped bracket 5 is inverted and installed above the baffle 3, and its two ends are connected to the housing 1 by screws 11 respectively; a second circular hole 51 is opened in the middle of the U-shaped bracket 5 corresponding to the first circular hole 31, and the annular column 6 is fixedly connected to the top of the U-shaped bracket 5, its interior is hollow and corresponds to the position of the second circular hole 51, and the bottom of the support rod 7 is fixedly connected to a circular baffle 10, and its top passes through the third circular hole 911, the first circular hole 31, the second circular hole 51 and the annular column 6 in sequence;

[0044] A top screw thread hole 61 is formed on the side of the annular column 6 away from the upper cover 4 , and an external thread is provided on the outside of the top screw 8 , and these are used in conjunction with each other to adjust the longitudinal height of the support rod 7 by loosening or tightening the top screw 8 .

[0045] Furthermore, the number of the arc-shaped racks 92 is at least three; the first arc-shaped teeth 921 and the second arc-shaped teeth 922 are different in size, for example: two specifications of livestock semen frozen straws of 0.5 ml and 0.25 ml are placed respectively, and the fumigation rack 9 has teeth of different sizes on both sides to accommodate the two specifications of frozen straws, and fix the straws to prevent them from moving left and right.

[0046] Furthermore, a scale portion 12 is provided on the inner wall of the thermal insulation layer 2 for observing the liquid nitrogen level.

[0047] The method of using the device is as follows: pour liquid nitrogen into the shell 1 to a suitable height, pass the support rod 7 through the third circular hole 911, the first circular hole 31, the second circular hole 51 and the annular column 6 on the fumigation rack, and fix the U-shaped bracket 5 to the shell 1 with a screw 11; adjust the top screw 8 so that the fumigation rack 9 is a certain distance away from the liquid nitrogen surface, arrange the frozen straws in sequence on the fumigation rack 9, loosen the top screw 8 after the frozen straws have been fumigated for a certain period of time, immerse the fumigation rack and the straws below the liquid nitrogen surface, and tighten the top screw 8 again.

[0048] The height of the fumigation rack 9 from the liquid nitrogen surface affects the cooling rate of the frozen straws, and thus affects the activity of semen. The height of the fumigation rack from the liquid nitrogen surface needs to be adjusted according to different species, different individuals, and straws of different specifications.
