Description

Technical Field

[0001] The utility model relates to the technical field of horse frozen semen refrigeration equipment, in particular to a semen storage device for horse artificial breeding. Background Art

[0002] Frozen horse semen is frozen horse sperm, typically used for fertilization and reproduction. This process involves placing several tubes in a semen bag, which is then tied with a string and placed in a liquid nitrogen tank. While this method of storage maintains the low-temperature environment required for semen preservation, it requires manual untying of the string to access the bag. Liquid nitrogen is very cold, making it difficult to open the bag and potentially causing frostbite. Therefore, the semen tubes must be thawed quickly after removal, as any delay can negatively impact the semen's activity.

[0003] The utility model, with publication number CN215809549U, proposes a device for refrigerating frozen horse semen in straw tubes, which relates to the technical field of frozen horse semen refrigeration equipment. The technical solution is as follows: it includes a liquid nitrogen tank containing liquid nitrogen and a refrigeration rack placed inside the liquid nitrogen tank. The refrigeration rack is provided with several storage tubes inside the refrigeration rack, and a vertical slide rail is provided on the inner side of the support rod. The outer wall of the storage tube is fixedly provided with a vertical sliding bar, and the sliding bar corresponds to the inner wall of the slide rail. The center of the refrigeration rack is provided with a lifting rod. The beneficial effect of the utility model is that several straw tubes containing horse semen can be placed in the storage tubes. When ready to be used, the handle is lifted, the support plate moves upward from the cavity, the storage tube is lifted, the upper cover is opened, and the straw tube is taken out. No human labor is required to untie the bag, which reduces the damage caused by the low temperature of liquid nitrogen to people, saves time in taking out the straw tubes of frozen semen, ensures that the thawing process can be carried out quickly, and ensures the activity of horse semen.

[0004] However, the above-mentioned prior art still has the following shortcomings when used: the temperature of liquid nitrogen is relatively low, which can easily cause frostbite to the operator's hands. In the prior art, the top opening of the liquid nitrogen tank needs to be opened when taking out and placing the capillary tube. When the top opening is opened, the area above the liquid nitrogen tank is exposed to a low-temperature environment. As a result, the operator can easily cause frostbite to his hands when taking out and placing the capillary tube from the top opening.

[0005] To this end, the utility model provides a semen storage device for artificial breeding of horses. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a semen storage device for artificial breeding of horses to solve the problems raised in the above-mentioned background technology. The present invention has the function of isolating the low temperature of liquid nitrogen radiation when taking and placing the straw containing horse semen, which can effectively prevent the operator's hands from being frostbitten.

[0007] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solution: a semen storage device for artificial breeding of horses, comprising a liquid nitrogen box and a storage straw, wherein a ring frame is rotatably connected to one side of the liquid nitrogen box, the ring frame and the upper part of the ring frame enter the liquid nitrogen box, the joint between the ring frame and the liquid nitrogen box is sealed, and the upper end surface of the ring frame is provided with placement grooves distributed around and used for placing the storage straw.

[0008] Furthermore, a guide sleeve is fixedly connected to one side of the liquid nitrogen box and is sleeved on the outside of the annular frame, and a sealing rubber sleeve is nested in the guide sleeve.

[0010] Furthermore, the inner circumferential wall of the annular frame is fixedly provided with resistance-increasing protrusions that are evenly distributed circumferentially, and the outer fixed sleeve of the inner guide wheel is provided with a resistance-increasing rubber sleeve.

[0011] Furthermore, a control motor is fixedly connected to the bottom of the support plate, and an output shaft of the control motor is fixedly connected to the inner guide wheel.

[0012] Furthermore, the inner peripheral wall of the placement groove is fixedly connected with a baffle plate close to the bottom and evenly distributed circumferentially, and the centripetal side of the evenly distributed circumferentially distributed baffle plate forms a limiting cavity for limiting the storage of the capillary tube.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a semen storage device for artificial breeding of horses, comprising a liquid nitrogen box 1 and a storage capillary 2. Liquid nitrogen is injected into the liquid nitrogen box 1, or a liquid nitrogen tank with a cooling function is installed in the liquid nitrogen box 1, the purpose of which is to provide a low-temperature refrigerated storage environment in the liquid nitrogen box 1, and the storage capillary 2 is used to store horse semen.

[0023] In this technical solution, a ring frame 3 is rotatably connected to one side of the liquid nitrogen tank 1. The ring frame 3 and a portion of the upper section thereof enter the liquid nitrogen tank 1. The joint between the ring frame 3 and the liquid nitrogen tank 1 is sealed. In specific implementation, a guide sleeve 11 is fixedly connected to one side of the liquid nitrogen tank 1 and is mounted on the outside of the ring frame 3. A sealing rubber sleeve 111 is nested within the guide sleeve 11. The provision of the sealing rubber sleeve 111 can prevent cold air from leaking out. The upper end surface of the ring frame 3 is provided with placement grooves 31 arranged in a circular pattern for storing capillaries 2. Some of the placement grooves 31 on the ring frame 3 are located inside the liquid nitrogen tank 1, while the rest are located outside the liquid nitrogen tank 1. When the ring frame 3 rotates, the placement grooves 31 inside and outside the liquid nitrogen tank 1 will switch positions. As a result, when removing and placing capillaries, the cold air generated by the liquid nitrogen will not leak out, and thus the operator's hands will not be frostbitten.

[0024] Furthermore, a support plate 12 is fixedly connected to one side of the liquid nitrogen tank 1. An outer guide wheel 4 and an inner guide wheel 5 are provided on the top of the support plate 12, located on the outer and inner sides of the annular frame 3, respectively. Both the outer guide wheel 4 and the inner guide wheel 5 abut against the annular frame 3. The guide wheel 5 may be a sheave structure, and its function is to assist the operation of the annular frame 3. The number of outer guide wheels 4 can be two, the purpose of which is to improve the stability of the support of the annular frame 3.

[0025] In this embodiment, the inner circumferential wall of the annular frame 3 is fixedly provided with circumferentially evenly distributed resistance-increasing protrusions 32, and the outer fixed sleeve of the inner guide wheel 5 is provided with a resistance-increasing rubber sleeve 51. When the inner guide wheel 5 rotates, the friction between the resistance-increasing rubber sleeve 51 and the resistance-increasing protrusions 32 is used to drive the annular frame 3 to rotate. In other words, controlling the rotation of the inner guide wheel 5 can drive the annular frame 3 to operate.

[0026] Furthermore, a control motor 6 is fixedly connected to the bottom of the support plate 12 , and an output shaft of the control motor 6 is fixedly connected to the inner guide wheel 5 , so that the control motor 6 provides driving force for the rotation of the inner guide wheel 5 .

[0027] In this embodiment, the inner wall of the placement groove 31 is fixedly connected with a baffle 311 close to the bottom and evenly distributed circumferentially. The centripetal side of the evenly distributed circumferential baffle 311 forms a limiting cavity for limiting the storage of the capillary 2. This arrangement facilitates the handheld storage capillary 2 to be taken out and placed in the placement groove 31.

[0028] Furthermore, ventilation holes 312 located between adjacent baffles 311 are provided at the bottom of the placement slot 31 . The ventilation holes 312 facilitate air circulation in the placement slot 31 .

[0029] Working principle: Before use, in order to increase the storage capacity, several annular racks 3 arranged vertically can be set up on the outside of the liquid nitrogen tank 1. When horse semen needs to be stored, the horse semen is injected into each storage tube 2, and then the storage tube 2 is held and inserted into the placement slot 31 located outside the liquid nitrogen tank 1. The control motor 6 is then started, and the control motor 6 drives the inner guide wheel 5 to rotate, and the inner guide wheel 5 drives the annular rack 3 to rotate, so that the placement slot 31 containing the storage tube 2 enters the liquid nitrogen tank 1. At this time, the storage tube 2 in the liquid nitrogen tank 1 is in a low-temperature storage state. When the horse semen needs to be taken out, the inner guide wheel 5 is controlled to rotate, and the annular rack 3 rotates to drive one of the storage tubes 2 to the outside of the liquid nitrogen tank 1. At this time, the storage tube 2 can be manually pulled out.

[0030] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
