[0024] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0025] Reference Figure 1-5The embodiment of the present invention is a high-efficiency and energy-saving cattle semen freeze-drying device, which includes a box body 1 and a box cover 3 hinged to the top of the box body 1. A sealing plate 2 is fixedly connected to the inside of the box body 1, and a ring-shaped partition 4 is fixedly connected to the bottom of the sealing plate 2. A liquid nitrogen freezing chamber 5 and a drying chamber 6 are formed inside the box body 1 through the partition 4. A plurality of first placement components for placing sperm storage test tubes are evenly arranged inside the liquid nitrogen freezing chamber 5. The first placement component includes a freezing tube 8 fixedly connected to the inside of the sealing plate 2, and a fixing rod fixedly connected to the inside of the freezing tube 8 and arranged near the bottom. 12. A movable rod 13 slidably connected to the inside of the fixed rod 12, a bottom plate 11 fixedly connected to the bottom end of the movable rod 13 and fitted with the bottom of the freezing tube 8, a pressure plate 15 fixedly connected to the top of the movable rod 13 and movably connected to the inside of the freezing tube 8, a spring 14 sleeved on the outside of the movable rod 13, a first pipe cover 9 covering the top of the freezing tube 8, a baffle 16 slidably connected to the outside of the freezing tube 8, a plurality of connecting rods 10 evenly and fixedly connected between the baffle 16 and the bottom plate 11, and a plurality of ventilation holes 17 opened inside the freezing tube 8 and arranged close to the baffle 16.

[0026] The processed semen of the breeding bull is divided into sperm storage tubes and then inserted into the inside of the freezing tube 8. The sperm storage tube is placed inside the freezing tube 8 and contacts the pressure plate 15. The movement of the pressure plate 15 pushes the bottom plate 11 downward through the movable rod 13. The downward moving bottom plate 11 realizes the opening of the bottom of the freezing tube 8. Moreover, the downward moving bottom plate 11 drives the baffle 16 downward through the connecting rod 10, so that the air vent 17 is connected to the liquid nitrogen freezing chamber 5. By injecting liquid nitrogen into the liquid nitrogen freezing chamber 5, the sperm storage tube can be quickly frozen. When the freezing is completed and the sperm storage tube needs to be taken out from the inside of the freezing tube 8, the sperm storage tube is taken out and separated from the pressure plate 15. The reset operation of the pressure plate 15 is realized under the action of the spring 14, so that the bottom plate 11 can be driven by the movable rod 13 to move upward to close the bottom of the freezing tube 8. At this point, the upwardly moving base plate 11, via connecting rod 10, pushes baffle 16 upward to seal vent 17, thereby isolating cryovial 8 from liquid nitrogen freezing chamber 5. This ensures the tightness of liquid nitrogen freezing chamber 5 during the removal and placement of sperm storage tubes, effectively preventing fluctuations in the internal environment caused by frequent removal and placement of sperm storage tubes, such as changes in temperature, humidity, and nitrogen concentration, thereby ensuring the quality and stability of the frozen semen. This excellent sealing performance also helps reduce liquid nitrogen consumption, lowering operating costs, achieving high efficiency and energy conservation, and demonstrating its high practicality.

[0027] A heater 22 and a temperature sensor 21 are installed within the drying chamber 6 to precisely control the temperature during the drying process. Multiple second placement assemblies are evenly distributed throughout the drying chamber 6. These second placement assemblies include a drying tube 23 fixedly connected to the top of the sealing plate 2, a placement tray 20 fixedly connected to the bottom of the sealing plate 2 and positioned below the drying tube 23, and a second tube cover 19 that covers the top of the drying tube 23.

[0028] The frozen sperm storage tube is placed on the placement tray 20 through the drying tube 23, the heater 22 in the drying chamber 6 is started, and the temperature sensor 21 monitors the temperature in the drying chamber 6 in real time to ensure the smooth progress of the semen drying process.

[0029] Insulation panels 7 are installed on the side of the partition 4 near the drying chamber 6 and on the inner surface of the housing 1. These panels effectively reduce heat transfer and improve the equipment's energy efficiency. Transparent panels 18 are embedded in the tops of the first and second tube covers 9, 19, facilitating observation of the sperm storage tubes placed within them. Each of the first and second tube covers 9, 19 is screwed together with the corresponding cryotubes 8 and drying tubes 23, facilitating opening and closing while ensuring a stable connection and a good seal.

[0030] Working principle: The processed semen of the breeding bull is divided into sperm storage tubes, which are then inserted into the inside of the freezing tube 8. The sperm storage tube is placed inside the freezing tube 8 and contacts the pressure plate 15. The movement of the pressure plate 15 pushes the bottom plate 11 downward through the movable rod 13, and the downward moving bottom plate 11 realizes the opening of the bottom of the freezing tube 8. Moreover, the downward moving bottom plate 11 drives the baffle 16 downward through the connecting rod 10, so that the air vent 17 is connected to the liquid nitrogen freezing chamber 5. By injecting liquid nitrogen into the liquid nitrogen freezing chamber 5, the sperm storage tube can be quickly frozen. When the freezing is completed and the sperm storage tube needs to be taken out from the inside of the freezing tube 8, the sperm storage tube is taken out and separated from the pressure plate 15. The reset operation of the pressure plate 15 is realized under the action of the spring 14, so that the bottom plate 11 can be driven by the movable rod 13 to move upward to close the bottom of the freezing tube 8. At this point, the upwardly moving base plate 11, via connecting rod 10, pushes baffle 16 upward to seal vent 17, thereby isolating cryovial 8 from liquid nitrogen freezing chamber 5. This ensures the tightness of liquid nitrogen freezing chamber 5 during the removal and placement of sperm storage tubes, effectively preventing fluctuations in the internal environment caused by frequent removal and placement of sperm storage tubes, such as changes in temperature, humidity, and nitrogen concentration, thereby ensuring the quality and stability of the frozen semen. This excellent sealing performance also helps reduce liquid nitrogen consumption, lowering operating costs, achieving high efficiency and energy conservation, and demonstrating its high practicality.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
