[0001] This application relates to the technical field of chicken embryo vaccine injection machines, specifically a chicken embryo vaccine injection machine with replaceable needles. Background Technology

[0002] The chicken embryo vaccine injection machine automates the inoculation process, including egg disinfection, sterile air drying, perforation, injection, and needle sterilization. The entire process is controlled by a programmable logic controller (PLC) to ensure accuracy and efficiency.

[0003] Most existing chicken embryo vaccine injection machines use threaded connections for their needles. However, due to the varying number of needles installed, specific tools are often used to clamp and secure the needles during installation and replacement to avoid injury to personnel. This method requires specific tools, making the installation and replacement process cumbersome and inconvenient.

[0004] Therefore, this application provides a chicken embryo vaccine injection machine with replaceable needles to solve the above problems. Utility Model Content

[0005] This application provides a chicken embryo vaccine injection machine with replaceable needles, aiming to solve the problem mentioned in the background art that the needles of existing chicken embryo vaccine injection machines are mostly connected by threads. However, due to the different number of injection tubes installed, in order to avoid personnel injury during the installation and replacement of needles, special tools are often used to clamp and fix the needles to complete the installation and replacement process. The above method requires the use of special tools, and the installation and replacement steps are cumbersome and inconvenient to use.

[0006] To achieve the above objectives, this application provides the following technical solution: a chicken embryo vaccine injection machine with replaceable needles, comprising an injection machine body, an electric push rod fixedly connected to the top of the injection machine body, a lifting plate fixedly connected to the output end of the electric push rod, a vaccine storage component provided on one side of the top of the lifting plate, a pneumatic pressurization component provided on the other side of the top of the lifting plate, a connecting hose provided on one side of both the vaccine storage component and the pneumatic pressurization component, and an injection mechanism provided at the bottom of the lifting plate;

[0007] Preferably, to address the problem that existing chicken embryo vaccine injection machines often use threaded connections for needles, and that due to varying numbers of needles installed, specific tools are often used to clamp and fix the needles during installation and replacement to avoid injury, this method is cumbersome and inconvenient. Therefore, the injection mechanism includes an injection needle connector located at the bottom of the injection needle tube. An injection needle mounting head is located outside the injection needle connector. An injection needle is fixedly connected to the bottom of the injection needle mounting head. Mounting grooves are formed on both sides of the inner side of the injection needle mounting head, and fixing holes are formed inside the mounting grooves. The two sides of the injection needle connector are fixed... The device is equipped with an installation block, inside which is a fixing block. The injection needle tip is pushed to the outside of the injection needle connector by the injection needle head. Pressing the fixing block compresses a spring on its side, causing the fixing block to enter the interior of the installation block. The installation block moves into the installation groove, and the fixing block, under the spring's rebound force, inserts into the fixing hole, thus fixing the injection needle head to the outside of the injection needle connector. A sealing block inside the injection needle head engages with a sealing groove at the bottom of the injection needle connector, improving the sealing performance of the connection between the injection needle head and the injection needle connector. This allows for convenient and quick installation and replacement of the injection needle head, making the operation simple, fast, and easy to use.

[0008] Preferably, to address the issue of convenient installation and replacement of injection needles, the mounting block is adapted to the mounting groove and is inserted into the mounting groove; the fixing block is adapted to the fixing hole and is inserted into the fixing hole. The mounting block and mounting groove allow for easy installation of the injection needle tube mounting head onto the outside of the injection needle tube connector, and the fixing block and fixing hole allow for easy fixing of the injection needle tube mounting head to the outside of the injection needle tube connector, thus facilitating the installation and replacement of injection needles and making them convenient to use.

[0009] Preferably, to address the issue of convenient operation of the fixing block, the fixing block is slidably connected to the mounting block, and a spring is provided inside the mounting block. The spring is fixedly connected between the inside of the mounting block and one end of the fixing block located inside the mounting block. When the fixing block compresses the spring on its side, the fixing block can easily return to its original shape, thus facilitating its operation.

[0010] Preferably, to solve the problem of sealing between the syringe connector and the syringe mounting head, a sealing block is fixedly connected inside the syringe mounting head, and a sealing groove is provided at the bottom of the syringe connector. The sealing block is adapted to the sealing groove and is inserted into the sealing groove. By inserting the sealing block into the sealing groove, the sealing performance of the connection between the syringe connector and the syringe mounting head can be improved, preventing leakage. The operation is simple and quick, and the use is convenient.

[0011] Preferably, to address the issue of accurately placing the chicken embryo under the needle during vaccine injection and avoid injection errors, the main body base of the injection machine has sliding grooves on both sides. Threaded rods are rotatably connected inside the two sets of sliding grooves. Moving blocks are positioned outside the threaded rods, and fixed clamping blocks are fixedly connected to the top of the moving blocks. A chicken embryo placement block is positioned on the top of the main body base, with the fixed clamping blocks symmetrically positioned on both sides of the chicken embryo placement block. A dual-axis motor is installed inside the main body base, and the dual-axis motor is fixedly connected to the threaded rods via a coupling. The dual-axis motor drives the two sets of threaded rods to rotate inside the sliding grooves. The threaded rods are threadedly connected to the externally positioned moving blocks, allowing the moving blocks to slide inside the sliding grooves. The moving blocks drive the two sets of fixed clamping blocks to move in opposite directions, thus fixing the chicken embryo placement block to the top of the main body base. This facilitates the positioning and fixation of the chicken embryo placed on top of the threaded rods, making the operation simple, quick, and convenient.

[0012] Preferably, in order to solve the problem of easy movement of the movable block, the threaded rod is threadedly connected to the movable block, the movable block is disposed inside the sliding groove, and the movable block is slidably connected to the sliding groove. The threaded rod is threadedly connected to the movable block, so that the movable block slides inside the injection needle connector under force. By sliding the movable block to the sliding groove, the direction and distance of movement of the movable block can be limited, thereby improving the stability of the movement of the movable block.

[0013] This injection mechanism pushes the injection needle mounting head to the outside of the injection needle connector using the injection needle tip. Pressing the fixing block compresses the spring on its side, causing the fixing block to enter the interior of the mounting block. The mounting block moves into the mounting groove, and the fixing block, under the spring's rebound force, inserts into the fixing hole, thus fixing the injection needle mounting head to the outside of the injection needle connector. The sealing block inside the injection needle mounting head inserts into the sealing groove at the bottom of the injection needle connector, improving the sealing performance of the connection between the injection needle mounting head and the injection needle connector. This allows for convenient and quick installation and replacement of the injection needle tip, and is simple, fast, and easy to use.

[0014] The injection mechanism features a dual-axis motor inside the main base of the injection machine. The motor is fixedly connected to threaded rods via a coupling. The motor drives two sets of threaded rods to rotate within a sliding groove. These threaded rods are threadedly connected to externally mounted moving blocks, allowing the moving blocks to slide within the groove. The moving blocks then drive two sets of fixed clamping blocks to move in opposite directions, securing the chicken embryo placement block to the top of the main base of the injection machine. This facilitates the positioning and fixation of the chicken embryo placed on top of the threaded rods, making the operation simple, quick, and convenient. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Example 1

[0025] This embodiment provides a chicken embryo vaccine injection machine with replaceable needles, such as... Figure 1-6 As shown, the replaceable needle chicken embryo vaccine injection machine includes an injection machine body 1, an electric push rod 2 is fixedly connected to the top of the injection machine body 1, a lifting plate 6 is fixedly connected to the output end of the electric push rod 2, a vaccine storage component 3 is provided on one side of the top of the lifting plate 6, a pneumatic pressurization component 4 is provided on the other side of the top of the lifting plate 6, a connecting hose 5 is provided on one side of both the vaccine storage component 3 and the pneumatic pressurization component 4, and an injection mechanism 7 is provided at the bottom of the lifting plate 6.

[0026] When the injection mechanism is activated, the lifting plate 6 is raised or lowered by the electric push rod 2, thereby pushing the needle at the bottom of the injection mechanism 7 to insert into the chicken embryo. The vaccine is then injected into the injection needle tube through the vaccine storage component 3 and the connecting hose 5. The vaccine inside the needle tube is then injected into the chicken embryo through the pneumatic pressurization component 4 and the connecting hose 5, thus completing the chicken embryo vaccine injection operation. The injection mechanism 7 allows for convenient and quick installation and replacement of the injection needle 73, and facilitates the positioning and fixation of the chicken embryo. The operation is simple, quick, and convenient.

[0027] Specifically, the injection mechanism 7 includes an injection needle connector 71 located at the bottom of the injection needle tube, an injection needle mounting head 72 located outside the injection needle connector 71, an injection needle head 73 fixedly connected to the bottom of the injection needle mounting head 72, mounting grooves 74 opening on both sides inside the injection needle mounting head 72, fixing holes 75 opening inside the mounting grooves 74, mounting blocks 76 fixedly connected to both sides of the injection needle connector 71, and fixing blocks 77 located inside the mounting blocks 76.

[0028] In use, the syringe tube mounting head 72 is pushed to the outside of the syringe tube connector 71 through the syringe needle 73. Pressing the fixing block 77 compresses the spring 80 on its side, causing the fixing block 77 to enter the interior of the mounting block 76. The mounting block 76 moves into the interior of the mounting groove 74. The fixing block 77 is subjected to the rebound force of the spring 80, causing the fixing block 77 to insert into the fixing hole 75, thereby fixing the syringe tube mounting head 72 to the outside of the syringe tube connector 71. The sealing block 78 inside the syringe tube mounting head 72 inserts into the sealing groove 79 at the bottom of the syringe tube connector 71, which can improve the sealing performance of the connection between the syringe tube mounting head 72 and the syringe tube connector 71. The syringe needle 73 can be installed and replaced conveniently and quickly. The operation is simple and quick, and it is easy to use.

[0029] Furthermore, the mounting block 76 is adapted to the mounting groove 74 and is inserted into the mounting groove 74, and the fixing block 77 is adapted to the fixing hole 75 and is inserted into the fixing hole 75. The mounting block 76 is adapted to the mounting groove 74, which makes it easy to install the injection needle tube mounting head 72 onto the outside of the injection needle tube connector 71. The fixing block 77 is inserted into the fixing hole 75, which makes it easy to fix the injection needle tube mounting head 72 onto the outside of the injection needle tube connector 71, thereby facilitating the installation and replacement of the injection needle head 73 and making it convenient to use.

[0030] Furthermore, the fixing block 77 is slidably connected to the mounting block 76. The mounting block 76 is provided with a spring 80 inside. The spring 80 is fixedly connected between the inside of the mounting block 76 and one end of the fixing block 77 located inside the mounting block 76. The fixing block 77 compresses the spring 80 on its side. Through the spring 80, the fixing block 77 can easily return to its original shape, making the operation of the fixing block 77 convenient.

[0031] The syringe tube mounting head 72 has a sealing block 78 fixedly connected inside, and the bottom of the syringe tube connector 71 has a sealing groove 79. The sealing block 78 is adapted to the sealing groove 79 and the sealing block 78 is inserted into the sealing groove 79. By inserting the sealing block 78 into the sealing groove 79, the sealing performance of the connection between the syringe tube connector 71 and the syringe tube mounting head 72 can be improved, and leakage can be avoided. The operation is simple and quick, and the use is convenient.

[0032] Example 2

[0033] Unlike Example 1, when injecting vaccines into chicken embryos, the chicken embryos need to be accurately placed under the needle to avoid injection errors. To this end, sliding grooves 81 are provided on both sides of the base of the injection machine body 1. Threaded rods 82 are rotatably connected inside the two sets of sliding grooves 81. Moving blocks 83 are provided outside the threaded rods 82. Fixed clamping blocks 84 are fixedly connected to the top of the moving blocks 83. Chicken embryo placement blocks 85 are provided on the top of the base of the injection machine body 1. Fixed clamping blocks 84 are symmetrically arranged on both sides of the chicken embryo placement blocks 85.

[0034] In use, a dual-axis motor is installed inside the base of the injection molding machine body 1. The dual-axis motor is fixedly connected to the threaded rods 82 via a coupling. The dual-axis motor drives the two sets of threaded rods 82 to rotate inside the sliding groove 81. The threaded rods 82 are threadedly connected to the externally installed moving blocks 83, so that the moving blocks 83 slide inside the sliding groove 81. The moving blocks 83 drive the two sets of fixed clamping blocks 84 to move in opposite directions. The two sets of fixed clamping blocks 84 fix the chicken embryo placement block 85 to the top of the base of the injection molding machine body 1, so as to facilitate the positioning and fixing of the chicken embryo placed on the top of the threaded rods 82. The operation is simple and quick and convenient to use.

[0035] Specifically, the threaded rod 82 is threadedly connected to the movable block 83, which is located inside the sliding groove 81 and is slidably connected to the sliding groove 81. The threaded rod 82 is threadedly connected to the movable block 83, so that the movable block 83 slides inside the injection needle connector 71 under force. By sliding the movable block 83 to the sliding groove 81, the direction and distance of movement of the movable block 83 can be limited, thereby improving the stability of the movement of the movable block 83.

[0036] It should be noted that the main body 1 of the injection machine and its internal components, including the electric push rod 2, vaccine storage assembly 3, pneumatic pressurization assembly 4, and dual-axis motor, are all existing equipment. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0037] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
