[0021] Artificial insemination technology in animal husbandry is a method of achieving reproduction by manually injecting the sperm of male animals directly into the reproductive tract of female animals. This technology can help livestock farmers improve reproductive efficiency, control the breeding season, and avoid problems such as disease transmission. Artificial insemination technology is widely used in animal husbandry, which can improve reproductive efficiency, reduce the risk of disease transmission, and help livestock farmers achieve the reproduction and cultivation of high-quality breeding animals. In animal husbandry, the collected semen is usually divided and filled into frozen semen straws 13, and then the frozen semen straws 13 are placed in liquid nitrogen for freezing. Before artificial insemination, the frozen semen straws 13 are thawed and the sperm is injected into the reproductive tract of female animals through an insemination gun to achieve artificial insemination. However, in the currently used equipment, multiple frozen semen straws 13 are usually placed together in a container, and then this container is placed in a liquid nitrogen tank for freezing and transportation. When taking out the frozen semen straws 13, the container is taken out of the liquid nitrogen tank, and then the frozen semen straws 13 are taken. After use, the remaining frozen semen straws 13 and the container are put back into the liquid nitrogen tank. In this storage method, the unused frozen semen straws 13 are taken out of the liquid nitrogen tank together with the frozen semen straws 13 that need to be taken out. Through research, it is found that if the operation is slow and the container is out of the liquid nitrogen tank for a long time, it is easy to cause the reduction of semen quality.

When storing or transporting, the lock 23 is locked to keep the outer cover body 22 buckled on the box body 21, and the freezing bin is kept closed, so that the frozen semen straws 13 in the freezing bin remain in a low-temperature state.

[0029] Place the box body 21 upright, that is, with the outer cover body 22 facing upwards. Open the outer cover body 22. The freezing bin and the thawing bin are two cavities respectively arranged on the box body 21, and the two cavities of the freezing bin and the thawing bin open on the top surface of the box body 21, and the frozen semen straws 13 can be taken and placed through the openings.

The fine tube picking and placing device is used to place the frozen fine tube 13 onto the fine tube bracket 12 or take out a frozen fine tube 13 from the fine tube bracket 12; The fine tube picking and placing device includes a fixed handle 51, a movable handle 52 hinged to the fixed handle 51, a first elastic member 53 connecting the fixed handle 51 and the movable handle 52, a push rod 54 movably connected to the fixed handle 51, and a chuck assembly connected to the fixed handle 51; the chuck assembly includes two clamping heads 55, a hinged plate 59 connecting the two clamping heads 55, and a second elastic member 56 capable of pushing the two clamping heads 55 closer; The push rod 54 includes a thin rod portion 541 and a thick rod portion 542; when the thin rod portion 541 contacts the clamping head 55, the second elastic member 56 can push the two clamping heads 55 to rotate in a direction approaching each other to clamp the frozen fine tube 13; when the thick rod portion 542 contacts the clamping head 55, the thick rod portion 542 pushes the two clamping heads 55 to rotate in a direction away from each other to release the clamped frozen fine tube 13. Rotating the movable handle 52 can compress the first elastic member 53 and push the push rod 54 so that the thick rod portion 542 contacts the clamping head 55; when the thick rod portion 542 contacts the clamping head 55, the two clamping heads 55 are in an open state. Move the clamping head 55 close to the frozen fine tube 13, and the frozen fine tube 13 pushes the push rod 54 to move so that the thin rod portion 541 contacts the clamping head 55, which can cause the clamping head 55 to close to clamp the frozen fine tube 13.

[0056] In this embodiment, the fine tube picking and placing device is as Figure 7 , Figure 8 and Figure 9 shown. The fine tube picking and placing device is used to place a frozen fine tube 13 onto the fine tube support 12 or take out a frozen fine tube 13 from the fine tube support 12. The movable handle 52 is a grip hinged to the fixed handle 51. When holding, the fixed handle 51 and the movable handle 52 are held simultaneously. The first elastic member 53 is a spring disposed between the fixed handle 51 and the movable handle 52, and the push rod 54 is disposed inside the fixed handle 51. The movable handle 52 is disposed at one end of the fixed handle 51, and the chuck assembly is disposed at the other end of the fixed handle 51.

[0057] A slider 57 is provided on the push rod 54, and a chute 58 is provided on the fixed handle 51. The slider 57 is within the chute 58, and the chute 58 and the slider 57 are used to limit the moving direction and position of the push rod 54.

[0058] The second elastic member 56 is a long strip-shaped elastic sheet, one end of which is connected to the fixed handle 51 and the other end is connected to the clamping head 55. A fine tube picking and placing device includes two second elastic members 56, and the two second elastic members 56 are respectively connected to the two clamping heads 55. The fine tube picking and placing device extends into the fine tube support 12, and the two elastic sheets respectively contact the two guide plates 48. The guide plates 48 press the arched elastic sheets towards the center, thereby pushing the two clamping heads 55 to close.

[0059] As Figure 12 and Figure 15As shown, the articulated parts of the two grippers 55 and the articulated plate 59 are arc-shaped heads. The arc-shaped heads are not concentric with the articulated shaft of the articulated plate 59, and the arc-shaped heads are eccentrically arranged with respect to the articulated shaft. Therefore, when the thin rod part 541 is between the arc-shaped heads of the two grippers 55, the second elastic member 56 can push the two grippers 55 to close; conversely, when the thick rod part 542 is between the arc-shaped heads of the two grippers 55, the thicker thick rod part 542 can push the two grippers 55 to open. The thin rod part 541 is at the end of the push rod 54.

[0060] In the specific implementation process, before gripping the frozen fine tube 13, the push rod 54 is pushed out so that the thick rod part 542 is between the two grippers 55, and the two grippers 55 are in an open state. When approaching the frozen fine tube 13, the frozen fine tube 13 pushes the push rod 54 to retract, moving the thin rod part 541 between the two grippers 55, and the two grippers 55 close. At this time, lifting the thin tube picking and placing device can take out one frozen fine tube 13 clamped by it.

[0061] In some embodiments, on the contact surfaces of the two grippers 55 and the frozen fine tube 13, there are card slots and anti-slip pads. The card slots match the arc of the frozen fine tube 13, and the anti-slip pads are arranged on the surfaces of the grippers 55. The card slots and the frozen fine tube 13 increase the stability of clamping the frozen fine tube 13.

[0062] When releasing the clamped frozen fine tube 13, pressing the movable handle 52 can push out the push rod 54 to open the two grippers 55.

[0063] As Figure 10 、 Figure 11 、 Figure 13 、 Figure 14 shown, the movable handle 52 is provided with an arc-shaped end at the end inside the fixed handle 51. The center of the arc-shaped end is offset from the center of the articulated shaft of the movable handle 52. Rotating the movable handle 52 can cause the arc-shaped end to swing, and thus rotating the movable handle 52 can move the push rod 54.

[0064] Furthermore, the thawing chamber includes a thawing and heat preservation layer 61 arranged in the cavity of the thawing chamber. Inside the thawing and heat preservation layer 61, there is a bracket; the bracket includes a plurality of support plates 62 and a connecting plate 63 connecting the plurality of support plates 62.

[0065] In this embodiment, as Figure 6 shown, the thawing and heat preservation layer 61 can be made of a heat-insulating material such as plastic. The support plates 62 are plate-shaped parts. The frozen fine tube 13 can be placed on the support plates 62, and the gap between the support plates 62 facilitates the picking and placing of the frozen fine tube 13.

[0066] In some embodiments, the upper surface of the pallet 62 includes two inclined surfaces, and the lowest points of the two inclined surfaces are at the center of the pallet 62. Such a pallet 62 can keep the frozen fine tube 13 on the pallet 62 at the center by gravity, preventing the frozen fine tube 13 from sliding on the pallet 62.

[0067] Furthermore, a heating medium is provided inside the thawing heat preservation layer 61, and the heating device 14 is used to heat the heating medium; a slide rail 64 is provided inside the thawing heat preservation layer 61, and the connecting plate 63 is connected to the slide rail 64; The thawing chamber further includes a driver 65 for driving the bracket to move up and down, and the slide rail 64 is used for guiding when the bracket moves up and down; when the bracket moves downward, the frozen fine tube 13 placed on the bracket can contact the heating medium, and when the bracket moves upward, the frozen fine tube 13 placed on the bracket can be separated from the heating medium. The thawing chamber further includes a temperature sensor 66 for detecting the temperature of the heating medium and a position sensor 67 for detecting the position of the bracket.

[0068] In this embodiment, the driver 65 can be a linear motor or a hydraulic cylinder or other driving devices capable of generating linear reciprocating movement. The heating medium can be water. The bottom area of the thawing heat preservation layer 61 is filled with the heating medium. The driver 65 can drive the pallet 62 to move up and down. Multiple pallets 62 can support the frozen fine tube 13 together from different positions in the length direction of the frozen fine tube 13, playing a role in stabilizing the frozen fine tube 13.

[0069] The driver 65 drives the pallet 62 and the frozen fine tube 13 on the pallet 62 to be immersed in the heating medium for heating, and can also lift the frozen fine tube 13 upward to separate it from the heating medium.

[0070] The temperature sensor 66 is used to detect the temperature of the heating medium. The position sensor 67 can be a proximity sensor or a grating sensor, and is used to detect the position of the bracket.

[0071] In some embodiments, the box body 21 further includes a space for placing the fine tube picking and placing device. An activity door 71 is provided on the box body. Opening the activity door 71 can pick and place the fine tube picking and placing device from this space.

[0072] In some embodiments, a control component 72 is further provided inside the box body 21.
