[0045] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Embodiment 1: Referring to Figures 1 to 11As shown, a fully automated immunization machine for poultry embryos includes a frame 8, along which are arranged in sequence:

[0046] The propulsion device 2 is used to push several egg trays 1 to move simultaneously along the platform;

[0047] Egg disinfection device 3 is used to disinfect embryos on the egg tray that are to be immunized;

[0048] Air drying device 4 is used to air dry the sterilized egg trays;

[0049] Inoculation device 5 is used to inoculate several embryos on an egg tray; it includes a shell-breaking component, an inoculation component, and a needle sterilization component; the shell-breaking component breaks the shells of the embryos; the inoculation component inoculates the embryos inside the broken-shelled eggs;

[0050] The sterilization unit is used to sterilize the injection needles;

[0051] The lateral movement component controls the inoculation device to move laterally along the width of the platform.

[0052] The propulsion device 2 in this application is used to simultaneously push several egg trays 1 placed on the platform 8, so that the egg trays 1 can move a certain distance at the same time; then the egg sterilization device 3 sterilizes the egg trays 1, and then the drying device 4 dries the egg trays 1. After drying, the egg trays 1 are placed under the inoculation device 5. Then the shell-breaking component breaks the shells of the embryos on the egg trays 1. After breaking the shells, the inoculation component inoculates the embryos in the embryos to achieve full-process immunization; at the same time, this application also provides a sterilization component, which, in conjunction with the lateral movement device, sterilizes the inoculation needle to prevent contamination.

[0053] The propulsion device 2 includes a push-pull shaft 21 arranged along the length of the platform 8 and on both sides of the width of the platform 8. A propulsion cylinder 24 drives the push-pull shaft 21 to move along the length of the platform 8. Several forks 22 are arranged on the push-pull shaft 21, and a rotary cylinder 23 is connected to the push-pull shaft 21 to drive its rotation. The propulsion cylinder 24 is located at the end of the push-pull shaft 21 and controls the push-pull shaft 21 to move back and forth along its length. A track 25 is provided on the platform 8, and the egg tray 1 slides along the track 25.

[0054] In use, when the egg tray 1 needs to be pushed, the rotary cylinder 23 rotates the push-pull shaft 21 by 90 degrees, and the shift fork 22 located below the track 25 rotates to the side of the track 25 (e.g., Figure 4 (As shown by the dotted line), the position of the shift fork 22 is higher than the bottom of the egg tray 1; the push cylinder 24 pushes the push-pull shaft 21 forward, and the shift fork 22 pushes the egg tray 1 on the track 25 forward into place; when pulling back, the rotary cylinder 23 rotates the push-pull shaft 21 90°, and the shift fork 22 located on the side of the track 25 returns to below the track 25 (as shown by the dotted line). Figure 4 (As shown by the solid line), at this time, the shift fork 22 is in the retracted state; the push cylinder 24 pulls the push-pull shaft 21 back to its original position, at which point the egg tray 1 on the track 25 remains stationary; the push device 2 completes one reciprocating motion. By repeating the above steps, several egg trays 1 can be moved simultaneously on the platform 8 by a certain distance.

[0055] The egg disinfection device 3 includes a disinfectant tank 34 mounted on a platform 8, several mixing spray chambers 35 mounted on the disinfectant tank 34 and connected to the sidewalls of the disinfectant tank 34, and a pressure tank 32 connected to the mixing spray chambers 35. The sidewalls of the mixing spray chambers 35 are connected to the disinfectant in the disinfectant tank 34 via pipes. The disinfectant tank 34 is connected to the disinfectant container 31 via hoses, and the disinfectant container 31 continuously supplies disinfectant to the disinfectant tank 34. A solenoid valve 36 is installed on the hoses to control the liquid level in the disinfectant tank 34. The mixing spray chambers 35 are connected to the pressure tank 32 via hoses, and the opening and closing of the hoses is controlled by a pressure switch 33, thereby controlling the opening and closing of the mixing spray chambers 35.

[0056] When the egg tray 1 moves below the egg sterilization device 3, the pressure switch 33 opens, and compressed air from the pressure tank 32 enters the mixing spray chamber 35 through its respective latex tubes. Driven by the high-speed airflow, the resulting negative pressure draws in the disinfectant solution tank 34, mixes it, and sprays it out through the nozzle onto the embryos in the egg tray 1. This location is the inoculation point. The spray volume is controlled by the on / off time of the pressure switch 33, and the liquid level in the disinfectant solution tank 34 is controlled by the solenoid valve 36.

[0057] The air-drying device 4 includes a fan 40, a high-efficiency filter 41 disposed below the fan 40, and a static pressure chamber 42 disposed below the high-efficiency filter 41; several air outlet nozzles 43 are connected to the bottom of the static pressure chamber 42. In this embodiment, the air-drying device 4 is disposed above the platform 8. In use, when the egg tray 1 is moved into place, the fan 40 rotates, and the air blown out passes through the high-efficiency filter 41 and enters the static pressure chamber 42, and then blows out from the air outlet nozzles 43 to blow air onto the embryos on the egg tray 1 below. The air blown on the same part as the part of the embryos disinfected in the previous step; this method can quickly dry the surface of the embryos and purify the air to ensure the sterility of the inoculation site.

[0058] In one embodiment, the transverse movement device includes a transverse axis 502 arranged along the width direction of the platform 8, left and right push cylinders 503 arranged parallel to the transverse axis 502, and an outer frame 505 capable of sliding along the transverse axis 502. Two transverse sliders 501 are fixedly arranged at the top of the outer frame 505, and the transverse sliders 501 are slidably arranged on the transverse axis 502. The output end of the left and right push cylinders 503 is connected to the transverse sliders 501 to control the movement of the left and right push cylinders 503, thereby realizing the movement of the outer frame 505 in the width direction of the platform 8. The inoculation device 5 is arranged on the platform 8.

[0059] The shell-breaking assembly includes a central frame 511 capable of vertical movement, several shell-breaking needles disposed at the bottom of the central frame 511, and a central frame lifter for controlling the vertical movement of the central frame 511. The central frame 511 is disposed within an outer frame 505 and can move vertically along the outer frame 505. In this embodiment, the central frame lifter is a central frame lifting cylinder 510, which is disposed at the top of the outer frame 505. Two vertical shafts 504 are disposed in the width direction of the outer frame 505, and central frame sliding bearings 513 are disposed on both sides of the central frame 511 in the width direction, and the central frame sliding bearings 513 move vertically. A lower needle plate 514 is disposed at the bottom of the central frame 511, and several shell-breaking needles 515 are fixedly disposed on the lower needle plate 514.

[0060] The lifting cylinder 510 of the middle frame drives the middle frame 511 to move vertically, thereby causing several shell-breaking needles 515 at the bottom of the middle frame 511 to slide vertically. When the egg tray 1 moves to the bottom of the middle frame 511, the middle frame 511 can be controlled to move downward, causing the shell-breaking needles 515 to break the embryo.

[0061] The inoculation assembly includes an inner frame 521 that can move vertically, a plurality of inoculation needles 524 disposed at the bottom of the inner frame 521, and an inner frame lifter that controls the movement of the inner frame 521 vertically; the inoculation needles 524 are disposed above the hatching needles 515, which are hollow, and after the hatching needles 515 hatch the embryo, the inoculation needles 524 pass through the hatching needles 515 to inoculate the embryo.

[0062] The inner frame lifting device is an inner frame lifting cylinder 520, which is fixedly installed above the middle frame 511. The output shaft of the inner frame lifting cylinder 520 suspends the inner frame 521. To ensure that the inner frame 521 can slide stably in the vertical direction, an inner frame sliding bearing 522 is provided on the inner frame 521. The inner frame sliding bearing 522 is fixed at both ends in the width direction of the inner frame 521, and slides on the vertical shaft 504. An upper needle plate 523 is provided at the bottom of the inner frame 521. When the inner frame 521 moves downward, the inoculation needle 524 can pass through the shell-breaking needle 515.

[0063] The vaccination assembly also includes a vaccine vial 532 and a dispensing tube 530 located at the top of the inner frame 521. The dispensing tube 530 distributes the vaccine solution in the vaccine vial 532 to several vaccination needles 524. An vaccination switch 531 is located at the outlet of the dispensing tube 530 to control the opening and closing of the dispensing tube 530. The vaccine vial 532 and the dispensing tube 530 are connected via an infusion tube 533. Sterile compressed air 534 is introduced into the vaccine vial 532, the infusion tube 533 is connected to the inlet of the dispensing tube 530, and the outlet of the dispensing tube 530 is connected to several vaccination needles 524 via the vaccination switch 531. In use, sterile compressed air 534 is forced into the vaccine vial 532, which then forces the vaccine solution into the dispensing tube 530, and subsequently into the vaccination needles 524, thus achieving vaccination.

[0064] The needle sterilization assembly is located on the side of the frame 8, and includes several sterilization solution tubes 541 corresponding to the inoculation needles 524. Two sets of needle sterilization assemblies are provided, each located on one side of the width of the frame 8; two sets of needle inoculation assemblies and two sets of needle breaking assemblies are also provided. Specifically, the two sets of needle sterilization assemblies are located on both sides of the width of the frame 8, and the two sets of inoculation needles 524 are arranged along the width of the frame 8. Simultaneously, the two sets of needle breaking assemblies 515 are also arranged along the width of the frame 8.

[0065] The side wall of the puncture needle 515 is provided with a residual liquid absorption tube 540. Several residual liquid absorption tubes 540 are connected to a residual liquid tube 542. The residual liquid tube 542 is connected to a vacuum generator 543. The end of the vacuum generator 543 away from the residual liquid tube 542 is connected to a compressed air tube 544.

[0066] While one set of piercing needles 515 and inoculation needles 524 are being used for immunization, another set of piercing needles 515 and inoculation needles 524 are being immersed in a disinfectant tube 541 for disinfection. When the piercing needles 515 and inoculation needles 524 are removed from the disinfectant tube 541 after the immersion disinfection is completed, the vacuum generator 543 is activated, and the residual liquid between the piercing needles 515 and inoculation needles 524 is absorbed through the residual liquid absorption tube 540.

[0067] When the egg tray 1 is in position below the inoculation device 5, the middle frame lifting cylinder 510 pushes the middle frame 511 downward. The middle frame 511 drives the lower needle plate 514 downward, which in turn drives the hatching needle 515 downward, allowing the hatching needle 515 to pierce the embryo. The needle insertion length control device controls the descent height of the middle plate to accommodate the inoculation of embryos of different sizes. Then, the inner frame lifting cylinder 520 pushes the inner frame 521 downward. The inner frame 521 drives the upper needle plate 523 downward, which in turn drives the inoculation needle 524. Moving downwards, the inoculation needle 524 penetrates the shell-breaking needle 515 and pierces the allantoic membrane of the embryo inside the egg. Then, the air pressure switch activates, opening the valve. The vaccine solution in the vaccine vial 532 (powered by clean compressed air 534) flows through the latex tube, dispensing tube 530, and inoculation needle 524, injecting it into the embryo inside the egg. Controlling the opening time of the air pressure switch controls the inoculation volume. After the inoculation operation is completed, the inner frame cylinder 520 and the middle frame cylinder 510 are raised to their positions, completing one inoculation cycle. Simultaneously, one set of shell-breaking needles 515 and inoculation needles 524 performs inoculation, while another set of shell-breaking needles 515 and inoculation needles 524 moves along with the inoculation. The inoculation needles 524 and shell-breaking needles 515 are inserted into the disinfectant tube 541 filled with disinfectant solution for immersion disinfection. After disinfection, the compressed air on the vacuum generator 543 is turned on on the disinfected needle plate, creating a vacuum that draws out any residual disinfectant between the inoculation needle 524 and the rupture needle 515. Simultaneously, the disinfectant system injects disinfectant into the disinfectant tube 541, squeezing out any previously contaminated disinfectant. After the middle frame 511 and inner frame 521 return to their original positions, the left and right pushing cylinders 503 actuate, pushing the outer frame 505 along the horizontal axis 502 to the other end, ready for inoculation with the disinfected needle. This completes one inoculation operation.

[0068] The working principle of this application is as follows:

[0069] (1) The egg trays 1 on the track 25 are pushed sequentially along the frame 8 by the propulsion device 2. When the egg trays 1 need to be pushed, the rotary cylinder 23 rotates the push-pull shaft 21 by 90 degrees, and the fork 22 located below the track 25 rotates to the side of the track 25, with the position of the fork 22 higher than the bottom of the egg trays 1. The propulsion cylinder 24 pushes the push-pull shaft 21 forward, and the fork 22 pushes the egg trays 1 on the track 25 forward to their position. When pulling back, the rotary cylinder 23 rotates the push-pull shaft 21 by 90 degrees, and the fork 22 located on the side of the track 25 returns to its position below the track 25. At this time, the fork 22 is in the retracted state. The propulsion cylinder 24 pulls the push-pull shaft 21 back to its position, and the egg trays 1 on the track 25 remain stationary. The propulsion device 2 completes one reciprocating motion. By repeating the above steps, several egg trays 1 can be moved simultaneously on the frame 8 by a certain distance.

[0070] (2) Afterwards, the egg tray 1 is moved below the egg sterilization device 3, the pressure switch 33 is turned on, and the compressed air in the pressure tank 32 enters the mixing spray chamber 35 through their respective latex tubes; driven by the high-speed airflow, the negative pressure formed draws the disinfectant in the disinfectant tank 34, mixes it, and sprays it out from the nozzle onto the embryos in the egg tray 1. This position is the inoculation position. The spray volume is controlled by the on / off time of the pressure switch 33, and the liquid level in the disinfectant tank 34 is controlled by the solenoid valve 36.

[0071] (3) Then the egg tray 1 is moved to the bottom of the drying device 4, the fan 40 rotates, and the blown air passes through the high efficiency filter 41 and enters the static pressure box 42. Then it is blown out from the air outlet nozzle 43 to blow air on the embryo eggs on the egg tray 1 below. The blowing part is the same as the part of the embryo eggs disinfected in the previous step. This method can make the surface of the embryo eggs dry quickly and purify the air to ensure the sterility of the inoculation site.

[0072] (4) Then, the egg tray 1 moves to the bottom of the inoculation device 5, and the middle frame lifting cylinder 510 pushes the middle frame 511 downward. The middle frame 511 drives the lower needle plate 514 downward, which in turn drives the hatching needle 515 downward, and the hatching needle 515 pierces into the embryo. The needle insertion length control device controls the descent height of the middle plate to accommodate the inoculation of embryos of different sizes. Then, the inner frame lifting cylinder 520 pushes the inner frame 521 downward. The inner frame 521 drives the upper needle plate 523 downward, and the upper needle plate 523 drives the inoculation needle 524. Moving downwards, the inoculation needle 524 passes through the inside of the hatching needle 515 and pierces the allantoic membrane of the embryo inside the egg. Then, the air pressure switch is activated, and the vaccine solution in the vaccine vial 532 (powered by clean compressed air 534) is injected into the embryo through the latex tube, the dispensing tube 530, and the inoculation needle 524. The opening time of the air pressure switch is controlled to control the inoculation volume. After the inoculation operation is completed, the inner frame cylinder 520 and the middle frame cylinder 510 are raised to their positions, and one inoculation cycle is completed.

[0073] (5) During inoculation, one set of piercing needles 515 and inoculation needles 524 are used for inoculation, while another set of piercing needles 515 and inoculation needles 524 are used simultaneously. The inoculation needles 524 and piercing needles 515 are inserted into the disinfectant tube 541 filled with disinfectant solution, and the piercing needles 515 and inoculation needles 524 are immersed for disinfection. After disinfection, the compressed air on the vacuum generator 543 is turned on on the disinfected needle plate to create a vacuum, which sucks out the residual disinfectant solution between the inoculation needles 524 and piercing needles 515; at the same time, the disinfectant system injects disinfectant solution into the disinfectant tube 541, squeezing out the previously contaminated disinfectant solution. After the middle frame 511 and inner frame 521 return to their original positions, the left and right pushing cylinders 503 are activated, pushing the outer frame 505 along the horizontal axis 502 to the other end, ready for inoculation with the disinfected needles. This completes one inoculation operation.

[0074] The propulsion device 2 in this application is used to simultaneously push several egg trays 1 placed on the platform 8, enabling the egg trays 1 to move a certain distance at the same time; then the egg sterilization device 3 sterilizes the egg trays 1, and then the drying device 4 dries the egg trays 1. After drying, the egg trays 1 enter the inoculation device 5 below, and then the hatching component hatches the embryos on the egg trays 1. After hatching, the inoculation component inoculates and immunizes the embryos inside the embryos, realizing full-process immunization; at the same time, this application also provides a sterilization component, which, in conjunction with the lateral movement device, sterilizes the inoculation needle 524 to prevent contamination; and the sterilization component, inoculation component, and hatching component are all provided in two sets, which can realize that while one set of sterilization component, inoculation component, and hatching component is performing inoculation, the other set is sterilizing, improving the efficiency of sterilization and inoculation.

[0075] Example 2: This example is similar in structure to Example 1, except that it also includes a laminar flow hood 9, a platform 8 passing through the laminar flow hood 9, an egg sterilization device 3, a drying device 4, and an inoculation device 5, all of which are set inside the laminar flow hood 9. A purification device 7 is set on the top of the laminar flow hood 9, which can purify the inoculation process and improve the safety of inoculation.

[0076] Example 3: Reference Figure 11 As shown, this embodiment is similar in structure to that in Embodiment 1 or Embodiment 2, except that an egg-lifting device 6 is provided below the platform 8 corresponding to the inoculation device 5 to lift several embryos on the egg tray 1 upwards. The egg-lifting device 6 includes a pushing cylinder 61, a pushing plate 63 connected to the output end of the pushing cylinder 61, and several support tubes 65 corresponding to the embryos, located above the pushing plate 63. A rubber support 66 is provided at the top of the support tubes 65. A limiting plate 67 is provided above the platform 8, and several egg holes corresponding to the embryos on the egg tray 1 are provided on the limiting plate 67. To make the pushing plate 63 move more stably in the vertical direction, sliding bushings 62 are provided on both sides of the pushing plate 63, and the sliding bushings 62 slide along the sliding vertical axis 64. The sliding vertical axis 64 is fixed in the vertical direction.

[0077] The working principle of this embodiment is as follows: When the egg tray 1 reaches below the inoculation device 5, the lifting cylinder 61 is activated, pushing the lifting plate 63 upward. The rubber support 66 lifts the embryo in the egg tray 1 upward, and the embryo is squeezed into the egg hole of the limiting plate 67. Since a spring is provided in the support tube 65, the rubber support 66 can extend and retract within the support tube 65. Under the action of the spring, the embryo is pressed firmly into the egg hole, and the upper edge of the embryo is neatly exposed above the egg hole. After the inoculation process is completed, the lifting cylinder 61 is reset, and the embryo falls back into the egg tray 1.

[0078] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
