[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 5 This utility model provides an embodiment of a high-efficiency cleaning nozzle for a livestock frozen semen filling machine, including a semen cup 15 and a body 1 on which the high-efficiency cleaning nozzle is installed. The semen cup 15 is placed inside the body 1 and is made of food-grade 304 stainless steel. The inside is mirror-polished and the surface roughness Ra≤0.4μm, which not only facilitates cleaning but also effectively prevents semen residue and bacterial growth. The semen cup 15 is equipped with a liquid level sensor, which can monitor the amount of semen or cleaning fluid stored inside in real time and display the remaining amount on the display screen 3. An operating table 2 is set on the front right side of the body 1. The operating table 2 adopts a touch panel design and is covered with a dirt-resistant and wear-resistant coating. The operator can accurately input core parameters such as filling volume, cleaning fluid flow rate, and number of cycles through preset programs or custom modes to ensure the accurate setting of equipment operating parameters. A display screen 3 is installed on the front right side of the machine body 1. The display screen 3 uses a high-resolution LCD panel, which can not only provide real-time feedback on operating parameters such as motor speed, pipeline pressure, and temperature in the form of dynamic charts, but also has a fault warning function. When abnormal data is detected, it can prompt the operator to handle it in time through sound and light, and provide a comprehensive display of the equipment's working process. The top of the machine body 1 is fixedly connected to the feed port 4, which is equipped with a photoelectric sensor and a one-way passage baffle structure. The photoelectric sensor monitors the entry of filling tubes in real time. When a filling tube is detected to be approaching, the baffle opens automatically, allowing only one filling tube to pass through at a time, avoiding blockage or filling chaos caused by multiple tubes entering at the same time; the edges of the feed port 4 are rounded to prevent scratching the outer wall of the filling tube. The inner wall of the machine body 1 is equipped with a drive assembly, which includes a support plate 5. The support plate 5 is made of high-strength stainless steel, and its bottom end is firmly fixed to the inner wall of the machine body 1 by bolts, providing a stable support platform for the motor 6 and ensuring that the motor 6 does not shake during operation.

[0034] A motor 6 is fixedly connected to the top of the support plate 5. The left side of the motor 6 is also fixed to the left side of the inner wall of the machine body 1 by high-strength bolts. The motor 6 is a high-precision stepper motor equipped with a closed-loop control system, which can accurately control the rotation angle each time, with an error range within ±0.5°, providing stable and precise rotation power for the rotating column 7. The drive end of the drive assembly is fixedly connected to the rotating column 7. The left side of the rotating column 7 is tightly connected to the drive end of the motor 6 through a coupling. Driven by the motor 6, it achieves intermittent rotation, driving the tube clamp 9 to send the filling tube to different work stations such as feeding, filling, cleaning, and discharging according to the set program. An auxiliary shaft 8 is fixedly connected to the right side of the rotating column 7. One end of the auxiliary shaft 8 is rotatably connected to the right side of the inner wall of the machine body 1 via a high-precision deep groove ball bearing. The auxiliary shaft 8 and the rotating column 7 are rigidly connected by a high-strength coupling and fixed to the inner wall of the machine body 1 by an outer rolling bearing. This effectively disperses the radial and axial forces generated when the rotating column 7 rotates, ensuring that the rotating column 7 rotates stably without deviation, greatly improving the operating accuracy and service life of the equipment. Multiple tube clamps 9 are fixedly connected externally to the rotating column 7. The tube clamps 9 are made of elastic silicone material with anti-slip textures inside, which can clamp the filling tube while avoiding damage to the tube wall. The spacing of each tube clamp 9 is precisely calculated to ensure a smooth transition of the filling tube between different workstations.

[0035] The internal structure of the machine body 1 houses a moving component, including a second motor 10. The external part of the second motor 10 is fixedly connected to the internal structure of the machine body 1 via shock-absorbing rubber pads, effectively reducing vibration and noise generated during motor operation. The second motor 10 is a high-torque servo motor, providing stable and powerful power output to drive the rotation of the turntable 11. The drive end of the second motor 10 is fixedly connected to the turntable 11, which is rotatably connected to the internal structure of the machine body 1 via a high-precision rotary support bearing. Driven by the second motor 10, it achieves smooth circular motion, thereby driving the coordinated movement of components such as the rotating shaft 12 and the support rod 13. The top of the turntable 11 is fixedly connected to the rotating shaft 12, which is offset 5cm from the center of the turntable 11. Through a specially designed eccentric structure, when the turntable 11 rotates, it drives the two support rods 13 to perform precise reciprocating swings, ensuring the linear motion accuracy of the slide plate 14. Two support rods 13 are rotatably connected to the top of the turntable 11. The outside of the support rods 13 is rotatably connected to the inside of the body 1 through a joint bearing. Driven by the rotating shaft 12, the support rods 13 swing back and forth with the joint bearing as the fulcrum, converting the circular motion of the turntable 11 into the linear motion of the slide plate 14.

[0036] The other end of the support rod 13 is rotatably connected to a slide plate 14. A high-precision linear guide rail is embedded in the bottom of the slide plate 14. The surface of the guide rail is hardened to a hardness of HRC55 or higher, ensuring that the slide plate 14 can achieve smooth and high-precision linear movement under the drive of the support rod 13. This ensures that the hose 16 installed at the top of the slide plate 14 and its connected injection tube 21 can be accurately aligned with the filling tube position. The top of the moving component is detachably connected to the hose 16. The hose 16 is detachably connected to the top of the slide plate 14 via a quick connector. The quick connector adopts a leak-proof design to ensure a firm connection and good sealing performance. The hose 16 is made of food-grade silicone material that is resistant to acids and alkalis and low temperatures. It has an internal steel wire reinforcement layer and can withstand pressures of over 0.8 MPa. It serves as a channel for conveying semen or cleaning fluid, stably delivering the medium extracted by the extractor to the sealing ring 19. The hose 16 is externally fixed with a threaded post 17. The threaded post 17 is made of high-strength alloy steel and has been nickel-plated, which has good rust resistance. It works with the threaded sleeve 18 to achieve a detachable connection between the hose 16 and the sealing ring 19, which facilitates equipment maintenance and component replacement.

[0037] The threaded column 17 is externally threaded with a threaded sleeve 18, which is threadedly connected to the sealing ring 19. The threaded sleeve 18 has anti-slip textures on its surface. By rotating the threaded sleeve 18, operators can quickly disassemble the injection tube 21 and hose 16 assembly within 15 seconds, requiring only 2-3 rotations. This significantly reduces maintenance difficulty and equipment downtime. One end of one of the hoses 16 is fixedly connected to an extractor, which uses a double-acting plunger pump equipped with a high-precision flow control valve and pressure sensor. By switching the media channel through a solenoid valve, precise extraction of semen or cleaning fluid can be achieved, with a flow control accuracy of ±1%. The other end of the hose 16 is detachably connected to a sealing ring 19. The sealing ring 19 has threaded grooves on its exterior and adopts a double-lip seal structure to form a redundant seal, effectively preventing leakage of semen or cleaning fluid during delivery, even under a pressure of 0.6 MPa. An airbag 20 is fixedly connected to the other side of the sealing ring 19. The airbag 20 is made of medical-grade silicone, which has good elasticity and biocompatibility. During the filling process, it automatically expands as the semen is injected, and can closely fit the inner wall of the frozen semen tube with different diameters of 1.5-4.5mm. This effectively eliminates the cleaning blind spots and filling leakage risks caused by unsuitable tube diameter, and ensures the sealing and accuracy of the filling process.

[0038] An injection tube 21 is fixedly connected to the other side of the air bladder 20. The injection tube 21 is made of medical-grade stainless steel, and its internal aperture is precision-machined with an error controlled within ±0.05mm. It is used to uniformly and stably inject semen or cleaning solution into the filling tube and is the terminal execution component for filling and cleaning operations. One end of another flexible tube 16 is fixedly connected to a deflator 22. The deflator 22 is equipped with a 0.22μm sterilization filter and a one-way valve with an opening pressure of 0.03MPa. During filling, when the pressure inside the filling tube reaches 0.03MPa, the one-way valve automatically opens to promptly release the air inside the tube. At the same time, the sterilization filter can effectively filter microorganisms in the air, avoiding the impact of air pressure changes and air pollution on the activity of frozen semen. The machine body 1 has an internal discharge port 23, which is funnel-shaped with a polished inner wall and a smooth, corner-free surface to facilitate the smooth sliding of the filling tubes. An infrared sensor is installed at the discharge port 23; when a filling tube is detected passing through, the sensor automatically records the quantity and displays the cumulative quantity on the display screen 3. A storage box 24 is installed at the front of the machine body 1. The storage box 24 has a drawer-style design with internal dividers for categorizing and storing the filling tubes. The bottom of the storage box 24 is equipped with casters for easy removal and handling, facilitating centralized storage and subsequent processing of the filling tubes.

[0039] Working Principle: In the livestock frozen semen filling operation, the operator first sets parameters through the control panel 2 on the right side of the front of the machine body 1, and inputs key data such as filling volume or cleaning time using the touch panel. At the same time, the display screen 3 provides real-time feedback on operating parameters such as motor speed and pressure value, and dynamically displays the equipment's workflow through a graphical interface. After the equipment is started, the drive components begin to run. The motor 6 fixed at the top of the support plate 5 serves as the core power source. Through precise control by a stepper motor, it drives the rotating column 7 to rotate a certain degree each time, realizing the intermittent movement of the tube clamp 9. The auxiliary shaft 8 on the right side of the rotating column 7 is rigidly connected to the rotating column 7 through a coupling and is fixed to the inner wall of the machine body 1 by the outer rolling bearing, ensuring stable rotation without deviation. This allows the filling tube to pass through the feed port 4 in sequence and be fixed by the tube clamp 9 to begin the filling operation.

[0040] Simultaneously, the moving components work in concert. Motor 2 10 drives turntable 11 in circular motion, and the rotating shaft 12 on turntable 11 drives two support rods 13 to reciprocate. Support rods 13 are connected to slide plate 14 via spherical bearings. The bottom of slide plate 14 is embedded with guide rails to achieve linear motion, ensuring that the hose 16 installed at the top of slide plate 14 and its connected injection tube 21 can be accurately aligned. During the filling process, the double-acting plunger pump extractor connected to the left hose 16 switches the medium channel through a solenoid valve, sequentially delivering the livestock semen in semen cup 15 to double-layer sealing ring 19, air bladder 20, and injection tube 21. The sealing ring 19 adopts a double-layer structure to form a redundant seal and prevent semen leakage. The air bladder 20 is made of medical-grade silicone and expands when semen is injected until it fits against the inner wall of the filling tube, adapting to various filling tube diameters. The air vent 22 connected to the right-side hose 16 includes a 0.22μm sterilization filter and a one-way valve with an opening pressure of 0.03MPa, which can promptly release air from the tube during filling to prevent changes in air pressure from affecting the activity of the frozen sperm. After filling is complete, the filling tube will fall from the outlet 23 into the collection box 24 for collection.

[0041] When cleaning of the injection tube 21 and tubing 16 is required after a period of use, replace the semen inside the semen cup 15 with cleaning fluid, and then clean the inner wall as usual when extracting semen. For equipment maintenance, the operator can rotate the threaded sleeve 18 to disengage it from the threaded post 17 and sealing ring 19, significantly improving equipment maintenance efficiency. The entire process, through precise mechanical structure coordination and intelligent control system operation, ensures both the accuracy and hygiene standards of frozen semen filling while achieving efficient and stable equipment operation.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
