Abstract
Description
Technical Field
[0001] This utility model relates to the field of poultry immunization technology, and in particular to a poultry injection positioning mechanism and a poultry vaccine injection device. Background Technology
[0002] Poultry vaccine injection devices are specialized equipment used in animal husbandry for large-scale vaccination. They usually include an injection mechanism for injecting vaccines and a positioning mechanism for fixing poultry.
[0003] The neck is a common injection site for poultry. However, the skin on the neck is thin and the subcutaneous tissue is loose, with dense feathers forming a natural barrier. Traditional poultry vaccine injection devices can only fix the bird's head in place. When the injection needle comes into contact with the dense feathers, the three-dimensional space formed by the feather roots and the epidermis disperses the vertical force of the needle, reducing penetration efficiency. The flexibility and elasticity of the feathers further exacerbate this phenomenon—the needle encounters multi-directional resistance during advancement, causing its actual trajectory to deviate from the preset path, making it difficult to act perpendicularly on the target tissue layer. This results in most poultry vaccine injection devices failing to achieve complete needle insertion and accurate vaccine injection when there is a lot of feathers on the bird's neck, affecting immunization efficacy and potentially leading to immunization failure. Utility Model Content
[0004] This invention solves the problems in related technologies and proposes a poultry injection positioning mechanism and a poultry vaccine injection device. Before injection, the device can hold the poultry's neck feathers and / or skin with a clamp, so that the injection position of the poultry's neck is better exposed under the injection needle. This reduces the obstruction of the injection needle during the advancement process, which is conducive to the complete insertion of the injection needle and accurate injection of the vaccine, reduces the probability of immunization failure, and ensures the immunization effect.

[0028] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0029] like Figure 1-2As shown, the poultry injection positioning mechanism of this utility model embodiment includes: a neck fixing frame 1 and a clamp 2. The neck fixing frame 1 is provided with an injection channel 11 suitable for the injection needle of the injection mechanism to pass through. The clamp 2 includes clamping wheels 21 disposed on the left and right sides of the injection channel 11. The clamping wheels 21 are used to clamp the poultry's neck feathers and / or skin. The clamping wheels 21 can be electrically rotated or manually rotated; this embodiment does not impose any limitation. It should be noted that... Figure 1 This is just one specific embodiment of the present invention. In some other embodiments of the present invention, the clamping wheels 21 on the left and right sides of the injection channel 11 may be arranged in multiple rows along the vertical direction, etc. This embodiment does not limit this.
[0030] Thus, the poultry injection positioning mechanism of this utility model provides clamping wheels 21 on both sides of the injection channel 11 on the neck fixing frame 1, which is suitable for the injection needle to pass through, to clamp the poultry neck feathers and / or skin. This allows the injection position of the poultry neck to be better exposed under the injection needle, reducing the obstruction of the injection needle during the advancement process. This facilitates the complete insertion of the injection needle and accurate injection of the vaccine, reduces the probability of immunization failure, and ensures the immunization effect.
[0031] In a preferred embodiment of this utility model, the clamping wheel 21 can be a roller with multiple protrusions or grooves on the clamping surface to increase the friction between the clamping wheel 21 and the feather or skin, thereby improving the stability of clamping.
[0032] In a preferred embodiment of this invention, the clamping wheel 21 on the left side of the injection channel 11 rotates counterclockwise, and the clamping wheel 21 on the right side of the injection channel 11 rotates clockwise. When the clamping wheels 21 rotate, the feathers and skin of the bird's neck can extend into the neck fixation frame 1 along the tangential direction of the clamping wheels 21 on both sides, so that the feathers and skin of the bird's neck are subjected to more balanced force on both sides, avoiding excessive local force on the bird and causing stress response, or even bone fracture or soft tissue contusion. In some other embodiments of this invention, the clamping wheels 21 on both sides of the injection channel 11 can be set to rotate clockwise or counterclockwise according to actual needs; this embodiment does not impose any limitation.
[0033] like Figure 3 As shown, in one embodiment of this utility model, the clamp 2 may further include a motor 22, which drives the clamping wheels 21 on both sides to rotate. In an embodiment of this utility model (not shown), the motor shaft of the motor may be directly connected to the rotation shaft of the clamping wheel to drive the clamping wheel.
[0034] like Figure 3As shown, in a preferred embodiment of the present invention, the clamp 2 may further include a transmission component 23. The transmission component 23 includes a helical gear shaft 231 disposed on the motor shaft 221 of the motor 22 and a worm gear 232 cooperating with the helical gear shaft 231. The worm gear 232 is coaxial with the clamping wheel 21.
[0035] When the motor shaft 221 of the motor 22 rotates, the helical gear 231 on the motor shaft 221 rotates synchronously with the motor shaft 221. Since the worm gear 232 is coaxial with the clamping wheel 21, the worm gear 232, which cooperates with the helical gear 231, can transmit power to the clamping wheel 21 through the rotating shaft 211 of the clamping wheel 21, providing driving force for the clamping wheel 21. The rotation direction of the clamping wheel 21 is the same as the rotation direction of the coaxial worm gear 232. When the rotation direction of the motor shaft 221 is clockwise, the helical direction of the helical gear 231 on the left side of the injection channel 11 is right-handed, and the helical direction of the helical gear 231 on the right side of the injection channel 11 is left-handed. In this case, the helical direction of the worm gear 232 on the left side of the injection channel 11 is counter-clockwise, and the helical direction of the worm gear 232 on the right side of the injection channel 11 is clockwise (e.g., ...). Figure 4 As shown in the figure, the arrow on the side of motor 22 indicates the rotation direction of motor shaft 221, and the arrow on clamping wheel 21 indicates the rotation direction of clamping wheel 21 and the worm gear 232 coaxial with it. Similarly, by setting the helical direction of helical gear shaft 231 and the rotation direction of motor shaft 221, the rotation direction of clamping wheels 21 on both sides can be controlled, so that clamping wheels 21 on both sides can rotate counterclockwise or clockwise at the same time, which will not be repeated here.
[0036] like Figure 5 and 6 As shown, in one embodiment of this utility model, the neck fixing frame 1 can be integrally formed with the mounting shell 24 of the motor 22, which facilitates the installation and fixing of the motor 22. The neck fixing frame 1 can be provided with a receiving space 12 for the clamping wheel 21 and a first through hole 13 suitable for the rotation shaft 211 of the clamping wheel 21 to pass through, so that the clamping wheel 21 can be directly set on the neck fixing frame 1, improving the integration of the mechanism and reducing the size of the mechanism.
[0037] In one embodiment of this utility model, the neck fixing bracket 1 is provided with a motor shaft mounting part 14, and the motor shaft mounting part 14 is provided with a second through hole 141 suitable for the motor shaft 221 to pass through. The helical gear shaft 231 is located on both sides of the motor shaft mounting part 14. By providing the motor shaft mounting part 14 on the neck fixing bracket 1 and restricting the helical gear shaft 231 to both sides of the motor shaft mounting part 14, the helical gear shaft 231 on the motor shaft 221 is prevented from disengaging from the worm gear 232 due to vibration or other uncontrollable factors, which would cause the transmission component 23 to fail, thereby improving the reliability and stability of the clamp 2.
[0038] In one embodiment of this utility model, the neck fixing bracket 1 may be provided with a baffle 15 between the injection channel 11 and the worm gear 232. The height of the baffle 15 may be higher than the highest point of the worm gear 232 to prevent the bird's feathers and / or skin from being caught in the transmission assembly 23 after the clamping wheel 21 loosens the bird's neck feathers and / or skin.
[0039] In addition, to achieve the above objectives, this utility model also proposes a poultry vaccine injection device.
[0040] like Figure 7 As shown, the poultry vaccine injection device of this utility model includes a poultry injection positioning mechanism 10 and an injection mechanism 20 as described above. The neck fixing frame 1 of the poultry injection positioning mechanism 10 is provided with an injection channel 11 suitable for the injection needle 201 of the injection mechanism 20 to pass through. The injection mechanism 20 can be a manual injection mechanism or an electric injection mechanism. The injection needle 201 of the injection mechanism 20 can be directly connected to an injection syringe containing the drug solution, or it can be connected to a drug pump, a drug container containing the drug solution, etc. through a flexible tube. This embodiment does not impose any limitations.
[0041] The poultry vaccine injection device of this utility model embodiment, since it includes the poultry injection positioning mechanism as described above, also has the above-mentioned beneficial effects.
[0042] In one embodiment of this invention (not shown), the poultry vaccine injection device may further include a contact sensor and a controller. The contact sensor is used to detect whether a poultry is approaching the neck support 1. The controller is used to control the gripper 2 to grip the poultry's neck feathers and / or skin when the contact sensor detects that a poultry is approaching the neck support 1, thereby achieving automated control of the gripper 2. Specifically, the contact sensor may be a temperature sensor, an optical sensor, a pressure sensor, etc., and this embodiment is not limited thereto.
