Description

Technical Field

[0001] This application relates to the field of artificial insemination technology for livestock and poultry, and in particular to a liquid injection structure and an insemination gun. Background Technology

[0002] In poultry and livestock farming, artificial insemination can improve reproductive efficiency and genetic quality. Artificial insemination procedures (e.g., collection, dilution, preservation, transfer, and insemination) typically rely on manual operation. In poultry and livestock insemination, at least two operators usually work together simultaneously. Specifically, at least one person needs to hold the animal to be inseminated, and at least another person needs to assist in injecting the semen into the insemination site. The level of coordination between the two operators affects insemination efficiency, resulting in a labor-intensive and inefficient process that limits the demand for high-efficiency insemination in large-scale farming. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. Therefore, the main objective of this application is to propose a liquid injection structure and an insemination gun, aiming to solve the problem of low insemination efficiency in artificial insemination of poultry and livestock.

[0004] To achieve the above objectives, this application proposes a liquid injection structure for use in insemination guns for poultry or livestock, the liquid injection structure comprising:

[0005] A driving component is fixedly installed on the insemination gun;

[0006] The injection tube is installed at the driving end of the driving component; the bottom end of the injection tube is flexible and moves back and forth along its axis under the driving action of the driving component, so as to extend and retract into the insemination site of the poultry or livestock and deliver semen.

[0007] Optionally, the injection tube includes:

[0008] A first tube, the first tube being used to deliver semen;

[0009] The second tube body is embedded in the first tube body, and the first tube body is fixed to the driving end of the driving component.

[0010] Optionally, the first tube body is made of a flexible material; the second tube body is made of a rigid material; and the bottom end of the first tube body protrudes from the second tube body.

[0011] Optionally, the first tube is made of a rigid material; the second tube is made of a flexible material; and the second tube covers the bottom end of the first tube.

[0015] Optionally, the flexible material is rubber or silicone; the rigid material is stainless steel.

[0016] Optionally, when the second tube is made of stainless steel, the outer surface of the second tube is processed with a super mirror finish.

[0017] Optionally, the bottom end of the first tube protrudes from the second tube by at least 1 mm.

[0018] Another technical solution proposed in this application is as follows: an insemination gun, including the liquid injection structure as described above.

[0019] This application provides a liquid injection structure and an insemination gun. The liquid injection structure is installed on the insemination gun.

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0037] This application addresses the problem of low insemination efficiency in artificial insemination of poultry and livestock by providing a liquid injection structure and an insemination gun. The liquid injection structure is installed on the insemination gun. When artificially inseminating poultry or livestock, the liquid injection structure has a retractable liquid injection tube that can be inserted into the insemination site. This allows the liquid injection tube to automatically extend into the insemination position under the drive of a driving component to deliver semen. This reduces the steps required for the operator to align and insert the insemination tube, enabling a single operator to perform the insemination operation by aligning the liquid injection structure with the insemination site, reducing the difficulty of the operation, and effectively improving insemination efficiency. For details, please refer to the following embodiments.

[0038] Please refer to the following: Figures 1 to 4 The first embodiment of this application provides an insemination gun 20 for inseminating poultry or livestock. The insemination gun 20 includes an injection structure 10. When artificially inseminating the poultry or livestock, the injection structure 10 has a retractable injection tube 11 that can be inserted into the insemination site. This allows the injection tube 11 to automatically extend into the insemination position under the drive of the drive member 12, delivering semen. This reduces the steps required for the operator to align and insert the tube, allowing the operator to simultaneously grasp the poultry or livestock to be inseminated. This facilitates single-person alignment and insemination of the injection structure 10, reducing operational difficulty and effectively improving insemination efficiency. Furthermore, because the injection tube 11 moves into the insemination site under the drive of the drive member 12, the consistency of the injection tube 11's movement during each insemination process is improved, ensuring that the injection tube 11 can reach the insemination position in each insemination process, and that the semen can be accurately delivered, thus improving the insemination success rate.

[0039] Furthermore, to achieve a seamless process during artificial insemination, encompassing semen storage, delivery, and injection into the insemination site, thus enhancing operator convenience and efficiency, the insemination gun 20 is equipped with a semen storage structure 21 and a semen delivery structure 22. These structures work in conjunction with the injection structure 10, which injects semen into the insemination site. This automates the storage, transfer, and injection of semen into the insemination site of poultry or livestock, improving consistency and efficiency in artificial insemination operations. This meets the high-efficiency insemination needs of large-scale farms and increases the success rate of artificial insemination. The insemination gun 20 also includes a frame 24. The frame 24, as the supporting and fixing structure in the insemination gun 20, serves to install and fix components such as the storage structure 21 and the delivery structure 22, ensuring the normal operation of functions such as semen storage, delivery, and insemination. The frame 24 can be composed of a base and a shell to install and fix components such as the delivery structure 22 and the injection structure 10, and provide protection. It can also be other structures. This application does not limit the shape, size, and structure of the frame 24, as long as it can ensure the normal operation of the delivery structure 22 and the injection structure 10. The storage structure 21 has a liquid storage chamber that maintains a preset storage temperature, which can store semen at the preset storage temperature to extend the semen preservation time and improve the success rate of artificial insemination. The preset storage temperature depends on the target species. For example, for artificial insemination of chickens, the preset storage temperature for semen is set to 35℃-40℃, which is close to the chicken's body temperature, to ensure sperm motility and fertilization capacity. The delivery structure 22 is connected to both the storage structure 21 and the injection structure 10. It delivers semen stored at a preset storage temperature to the injection structure 10 at a preset volume. The preset volume is the amount of semen to be inseminated in each artificial insemination of poultry or livestock. For example, for chickens, the semen volume should be 0.02ml-0.04ml to ensure an effective fertilization rate. To maintain hygiene and improve the success rate of insemination, the insemination gun 20 also includes a cleaning structure 23. At least part of the cleaning structure 23 is fitted onto the injection tube 11 and is used to clean the injection tube 11. When artificially inseminating multiple poultry and livestock, the injection tube 11 will come into contact with the insemination sites of different individuals, making it susceptible to contamination with bacteria and impurities. The cleaning structure 23 can clean the injection tube 11 promptly, preventing cross-infection and ensuring the hygiene of each insemination operation. For example, in large-scale chicken farms, when artificial insemination is performed on multiple chickens, the cleaning structure 23 can clean the discharge part before and after each insemination to ensure that the semen is not contaminated and improve the success rate of insemination.

[0040] Please refer to the following: Figures 3 to 5In some embodiments, the injection structure 10 includes a drive member 12 and an injection tube 11. The drive member 12 is fixedly installed in the frame 24 of the insemination gun 20. The injection tube 11 is connected to the delivery structure 22 in the insemination gun 20 and can be slidably installed on the insemination gun 20. The injection tube 11 is installed at the drive end of the drive member 12 and reciprocates along its axial direction under the drive of the drive member 12, so that the injection tube 11 can extend or retract relative to the frame 24 in the insemination gun 20 along its own axial direction. For example, when artificially inseminating chickens, the drive member 12 can be a small motor with a lead screw and nut mechanism. The rotation of the motor drives the lead screw to rotate, thereby causing the injection tube 11 connected to the nut to move axially; the drive member 12 can also be a telescopic cylinder, the drive rod of the telescopic cylinder is connected to the injection tube 11, thereby causing the injection tube 11 to move axially with the drive rod. When insemination is required, the bottom end of the injection tube 11 extends and is inserted into the insemination site of the chicken. After insemination, the injection tube 11 retracts. This design allows for precise control of the position of the injection tube 11, ensuring accurate injection of semen into the insemination site and improving the accuracy, success rate, and efficiency of insemination. The bottom end of the injection tube 11 extending into the insemination site is also flexible, allowing it to adapt to the physiological structure of the insemination site in poultry or livestock, reducing the risk of damage. The injection structure 10 is also equipped with a one-way valve 13, which connects the delivery structure 22 and the injection tube 11. Specifically, the one-way valve 13 is installed on the pipe (not shown) used to connect the delivery structure 22 and the injection tube 11. The delivery structure 22 delivers a preset volume of semen to the injection tube 11 in one direction through the one-way valve 13, preventing backflow of semen within the injection structure 10 and ensuring the accuracy and stability of semen delivery.

[0041] Please refer to the following: Figures 4 to 7In some embodiments, the injection tube 11 includes a first tube body 111 and a second tube body 112. The first tube body 111 is connected to the delivery structure 22 and is used to dispense semen. The first tube body 111 is embedded in the second tube body 112, and the first tube body 111 is fixed to the drive end of the drive member 12. When performing artificial insemination on poultry or livestock, the first tube 111 can be made of a flexible material such as rubber or silicone, and the bottom end of the first tube 111 protrudes from the second tube 112 to better adapt to the physiological structure of the insemination site of the poultry or livestock, reducing the risk of damage. Especially when performing artificial insemination on some smaller poultry with more fragile physiological structures, such as canaries, the flexible first tube 111 can gently contact the insemination site, reducing the possibility of injury. The second tube 112 is made of a rigid material such as stainless steel or copper, hard plastic, ceramic, etc., to provide support and protection for the first tube 111, ensuring that the injection tube 11 can stably extend and retract under the drive of the drive component 12, accurately complete the insemination operation, and improve the insemination success rate. The bottom end of the first tube 111 protrudes from the second tube 112 by at least 1 mm, meaning the flexible portion at the bottom of the injection tube 11 is at least 1 mm long, ensuring that the bottom end of the injection tube 11, in contact with the insemination site, will not cause damage. Conversely, if the second tube 112 is made of a flexible material and the first tube 111 is made of a rigid material, the second tube 112 covers the bottom end of the first tube 111, which also allows the injection tube 11 to gently contact the insemination site, reducing the possibility of damage.

[0042] Please refer to the following: Figure 8 and Figure 9 Furthermore, the injection tube 11 may also include a third tube body 113, which is sleeved around the outer periphery of the first tube body 111 and embedded in the second tube body 112, located between the first tube body 111 and the second tube body 112. When artificially inseminating poultry or livestock, if the first tube body 111 and the second tube body 112 are made of rigid material, and the third tube body 113 is made of flexible material, the bottom end of the third tube body 113 protrudes from the second tube body 112, and the bottom end of the third tube body 113 covers the bottom end of the first tube body 111. This structural design allows the flexible third tube body 113 to separate the first tube body 111 from the insemination site during insemination, contacting the insemination site of the poultry or livestock, reducing damage. Simultaneously, the rigid first tube body 111 and the second tube body 112 ensure the structural strength and stability of the injection tube 11, improving the insemination effect. The bottom end of the third tube 113 protrudes from the second tube 112 by at least 1 mm, meaning the length of the flexible portion at the bottom of the injection tube 11 is at least 1 mm, ensuring that the bottom end of the injection tube 11 in contact with the insemination site will not cause damage.

[0043] In practical applications, flexible materials are typically made of rubber or silicone, which possess excellent flexibility, elasticity, and biocompatibility. These materials can adapt to the physiological structures of different insemination sites in poultry or livestock, reducing the risk of damage. Rigid materials are typically made of stainless steel, copper, hard plastics, or ceramics. Stainless steel offers high strength, corrosion resistance, and hygiene, ensuring the structural stability of the injection tube 11 and preventing corrosion from semen or the external environment during insemination. This ensures the lifespan of the insemination gun 20 and the safety of the insemination operation, making it widely applicable in various artificial insemination scenarios for poultry and livestock, such as chickens, pigs, and cattle. When the first tube 111 and the second tube 112 are made of stainless steel, a super-mirror finish can be achieved, resulting in a low surface roughness, enhanced antibacterial properties, and easier cleaning, ensuring accurate and uncontaminated semen delivery.

[0044] This application provides a liquid injection structure and an insemination gun. The liquid injection structure is installed on the insemination gun. When performing artificial insemination on the insemination site of poultry or livestock, the liquid injection structure has a retractable liquid injection tube that can be inserted into the insemination site. This allows the liquid injection tube to automatically extend into the insemination position of the insemination site under the drive of a drive component to deliver semen. This reduces the steps required for the operator to align and insert the insemination tube, and helps the operator to perform insemination by aligning the liquid injection structure with the insemination site by a single person, reducing the difficulty of the operation and effectively improving the insemination efficiency.
