Description

Technical Field

[0001] This application relates to the field of chicken embryo virus culture technology, and in particular to a device for launching virus projectiles and equipment for producing virus-infected chicken embryos. Background Technology

[0002] Chicken embryo culture is a method used to culture certain viruses that are sensitive to chicken embryos. It involves injecting a virus strain into a 9-day-old chicken embryo and allowing the strain to be cultured and multiplied inside the embryo.

[0003] During the injection of the virus strain into the chicken embryo, an injection hole is made on the eggshell of the chicken embryo at a position corresponding to the air cell inside the eggshell using a hollow impact head. A syringe is inserted into the hollow structure of the impact head to inject the virus strain into the allantoic cavity inside the eggshell along the hollow interior of the impact head. The impact head and syringe are then removed, and the injection hole is sealed.

[0004] However, the method of using an impact head to create injection holes in the eggshell of chicken embryos in the aforementioned related technologies can easily cause cracks in the eggshell, allowing external viruses to easily enter the eggshell through the cracks, thus leading to breeding failure. Summary of the Invention

[0005] This application provides a device for launching viral pellets and a production equipment for viral chicken embryos, which solves the technical problem in the above-mentioned related technologies that the method of using an impact head to open an injection hole in the eggshell easily leads to cracks in the eggshell, allowing external viruses to easily enter the eggshell through the cracks, thus causing cultivation failure.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0009] The carrying mechanism is used to carry the target chicken embryo to be injected with the toxin pellet, and the carrying mechanism can drive the target chicken embryo to move toward the launching mechanism so that the target chicken embryo comes into contact with the launching mechanism;

[0010] The launching mechanism is located between the carrying mechanism and the dropping mechanism. The launching mechanism is used to accelerate the toxic pellet and shoot the toxic pellet with a preset speed into the eggshell of the target chicken embryo.

When the opening of the first groove is opposite to the opening of the second groove, a receiving cavity is formed to accommodate one of the toxic spore pellets.

[0014] The first and second rotating wheels rotate in opposite directions. The first and second rotating wheels are used to receive the toxic pellet when the first and second grooves are close to each other, and to discharge the toxic pellet toward the launching mechanism when the first and second grooves are far apart.

[0016] The first conduit is disposed on the side of the first and second rotating wheels facing away from the launching mechanism, and the first conduit is used to guide the toxic projectile into the receiving cavity;

[0017] The second conduit is disposed on the side of the first and second rotating wheels facing the launching mechanism, and the second conduit is used to guide the strain projectile that has detached from the receiving cavity to the launching mechanism.

[0018] In one possible implementation, the launching mechanism includes a third and a fourth rotating wheel that cooperate with each other;

[0019] The third rotating wheel has a first annular groove on its outer periphery, and the fourth rotating wheel has a second annular groove on its outer periphery; the first annular groove and the second annular groove form a firing hole on opposite sides to accommodate the poison projectile, and the diameter of the firing hole is less than or equal to the diameter of the poison projectile.

[0020] The third and fourth rotating wheels rotate in opposite directions to drive the toxic projectile entering the firing port toward the target chicken embryo on the carrying mechanism.

[0021] In one possible implementation, the launching device further includes a guiding structure;

[0022] The guide structure is located on the side of the launching mechanism facing the launching port of the launching mechanism. The guide structure has a through hole, through which the guide structure guides the toxic pellet fired from the launching port to the target chicken embryo.

[0023] In one possible implementation, the launching device further includes a shock absorber;

[0024] The shock absorber is disposed on the side of the guide structure facing the bearing mechanism, the shock absorber communicates with the through hole, and the shock absorber covers the side of the target chicken embryo facing the launching mechanism.

[0025] In one possible implementation, the launching device further includes a buffer pad covering the inner surface of the shock absorber, so that the target chicken embryo abuts against the shock absorber through the buffer pad.

[0026] In one possible implementation, the load-bearing mechanism includes a drive unit, a support component, and a support structure;

[0027] The drive unit is connected to the support assembly, the support structure is disposed on the support assembly, and the support structure has a support groove on the side facing the launching mechanism, the support groove being used to support the target chicken embryo;

[0028] The drive unit drives the support structure to move toward the launching mechanism by driving the support component.

[0029] In one possible implementation, the support structure includes a plurality of support arms disposed at one end of the support assembly facing the launching mechanism, and the plurality of support arms surround the outer periphery of the support assembly and form the support groove.

[0030] In one possible implementation, the support assembly includes a first support rod, a second support rod, and a buffer.

[0031] One end of the first support rod is connected to the support structure. The side of the first support rod facing away from the support structure has a receiving groove. The buffer is disposed in the receiving groove. A portion of the second support rod is located in the receiving groove. The second support rod is connected to the first support rod through the buffer. The second support is connected to the drive unit.

[0032] The drive unit drives the first support rod and the supporting structure to move toward the launching mechanism by driving the second support rod.

[0033] In one possible implementation, the launching device further includes a storage mechanism located on the side of the feeding mechanism opposite to the launching mechanism;

[0034] The storage mechanism includes a storage section and a conveying port. The storage section is used to store the strain pellets to be conveyed. The conveying port is connected to the storage section, and the strain pellets in the storage section fall into the feeding mechanism through the conveying port.

[0035] In one possible implementation, the storage mechanism further includes a vibration device disposed in the storage section, which, when in operation, causes the storage section to vibrate and causes the strain pellets blocked in the delivery port to be discharged.

[0036] In one possible implementation, the transmitting device further includes a camera mechanism and a control mechanism;

[0037] The camera mechanism and the transmitting mechanism are both electrically connected to the control mechanism. The camera mechanism is used to acquire a three-dimensional image of the eggshell of the target chicken embryo facing the transmitting mechanism and to send the acquired three-dimensional image to the control mechanism.

[0038] The control mechanism calculates the radius of curvature of the eggshell of the target chicken embryo facing the launching mechanism based on the three-dimensional image, and adjusts the launching speed of the launching mechanism to launch the toxic projectile based on the radius of curvature;

[0039] The launch velocity of the toxic projectile of the launching mechanism increases as the radius of curvature decreases.

[0040] A second aspect of this application provides a production equipment for chicken embryos containing a viral strain, which includes a conveying mechanism, a support platform, a screening mechanism, and a plurality of launching devices for viral pellets as described above.

[0041] The carrier platform is disposed on the conveying mechanism. The carrier platform has multiple carrier seats. Each carrier seat is used to place a target chicken embryo to be injected with the strain projectile. Each launching device launches the strain projectile at the target chicken embryo on one of the carrier seats.

[0042] The conveying mechanism drives the carrier platform to move, moving the injected target chicken embryo to the screening mechanism, which is used to screen out the target chicken embryo that has cracked.

[0043] In one possible implementation, the launching device includes a launching mechanism and a carrying mechanism;

[0044] The launching mechanism is located above the support base, and the support mechanism is located below the support base. The support base has a placement slot for placing the target chicken embryo.

[0045] The bottom of the placement slot has a connecting opening, through which the supporting mechanism passes into the placement slot and supports the target chicken embryo in the placement slot as it moves toward the launching mechanism.

[0046] This application provides a device for launching viral pellets and a production equipment for viral chicken embryos. The launching device includes a feeding mechanism, a launching mechanism, and a carrying mechanism. The feeding mechanism delivers viral pellets one by one to the launching mechanism, controlling the delivery of pellets sequentially to avoid blockage caused by multiple pellets entering the launching mechanism and facilitating control of the launching speed of each pellet. The carrying mechanism carries the target chicken embryo to be injected with the viral pellet and drives the embryo towards the launching mechanism, ensuring contact and improving stability during movement. The launching mechanism, located between the carrying mechanism and the feeding mechanism, accelerates the viral pellets and propels them at a preset speed into the eggshell of the target chicken embryo. This allows the viral pellets to be directly injected into the eggshell under the drive of the launching mechanism, avoiding the problem of eggshell cracks near the injection hole edge when removing the impact head from the eggshell, as seen in related technologies, thus improving the success rate of breeding.

[0084] Many vaccines used in daily life, such as human influenza vaccines (e.g., the currently scarce H1N1 influenza vaccine), rabies vaccines, measles vaccines for children, and mumps virus serum; and influenza vaccines (avian influenza vaccines), Newcastle disease vaccines, and infectious bronchitis vaccines for poultry (chickens, ducks, geese, etc.), all require culture in 9-day-old chicken embryos (fertilized eggs). This is because egg embryos have advantages such as low tissue differentiation, a wide range of sensitivities, and no antibody production against inoculated viruses, thus gaining widespread application. Using 9-day-old chicken embryos as a culture medium to inoculate viruses into the embryos can be used for virus isolation, virus amplification, virus virulence titration, neutralization tests, and antigen and vaccine production.

[0085] The process of culturing vaccines in chicken embryos: A 2-3 mm diameter impact head is used to puncture a 9-day-old egg embryo. After the eggshell is punctured, the virus strain is injected into the live chicken embryo through the needle, and then the virus strain grows inside the chicken embryo.

[0086] As described in the background section, the existing method of using an impact head to create an injection hole in the eggshell is prone to causing cracks in the eggshell. External viruses can easily enter the eggshell through these cracks, leading to cultivation failure. This problem arises because impact heads are often made of metal. After high-frequency operation, fatigue damage can cause the impact head to bend. When passing through the injection hole, the bent portion of the impact head has difficulty passing through, making the eggshell near the injection hole prone to cracking. Furthermore, when the impact head is removed from the eggshell, the shell membrane may be wrapped around its outer surface. This increases the outer diameter of the impact head compared to when it is not inserted into the eggshell, resulting in an outer diameter larger than the inner diameter of the injection hole. Removing the impact head with the shell membrane from the injection hole can cause the eggshell near the injection hole to crack due to the interference fit.

[0087] To address the aforementioned technical problems, this application provides a device for launching viral pellets and a production equipment for viral chicken embryos. The launching device includes a feeding mechanism, a launching mechanism, and a carrying mechanism. The feeding mechanism delivers viral pellets one by one to the launching mechanism, controlling the delivery of each pellet to avoid blockage caused by multiple pellets entering the launching mechanism and facilitating control of the launching speed of each pellet. The carrying mechanism carries the target chicken embryo to be injected with the viral pellet and drives the target chicken embryo towards the launching mechanism, ensuring contact between the embryo and the mechanism, thus improving the stability of the embryo during movement. The launching mechanism is located between the carrying mechanism and the dropping mechanism. The launching mechanism is used to accelerate the virus-injected projectile and shoot the projectile with a preset speed into the eggshell of the target chicken embryo. This enables the virus-injected projectile to be directly shot into the eggshell of the chicken embryo under the drive of the launching mechanism, avoiding the use of an impact head to drill holes in the eggshell in related technologies, and avoiding the problem of cracks in the eggshell near the edge of the injection hole when the impact head is removed from the eggshell, thus improving the success rate of breeding.

[0088] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, 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 a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0089] refer to Figure 1 This application provides a launching device 10 for a poison projectile 60, which may include a dropping mechanism 11, a launching mechanism 12, and a carrying mechanism 13. The launching mechanism 12 is located between the carrying mechanism 13 and the dropping mechanism 11, with the dropping mechanism 11 above the launching mechanism 12 and the carrying mechanism 13 below the launching mechanism 12. The poison projectile 60 enters the dropping mechanism 11 from above, and the dropping mechanism 11 delivers the projectiles one by one to the launching mechanism 12. This avoids blockage of the launching mechanism 12 when multiple poison projectiles 60 enter it, reducing the failure rate of the launching device 10. Furthermore, the fact that the poison projectiles 60 enter the launching mechanism 12 one by one through the dropping mechanism 11 facilitates the launching mechanism 12 in controlling the launching speed of each poison projectile 60, thereby improving the controllability of the launching device 10.

[0090] refer to Figure 1The carrier mechanism 13 is used to carry the target chicken embryo 50 to be injected with the viral strain projectile 60, and the carrier mechanism 13 can drive the target chicken embryo 50 to move towards the launching mechanism 12 so that the target chicken embryo 50 comes into contact with the launching mechanism 12. By setting the carrier mechanism 13, the stability of the target chicken embryo 50 during the movement towards the launching mechanism 12 can be improved. In specific implementation, the carrier mechanism 13 can move relative to the launching mechanism 12, and the target chicken embryo 50 is placed on the carrier mechanism 13. Then, the carrier mechanism 13 and the target chicken embryo 50 placed on the carrier mechanism 13 can move together towards the launching mechanism 12. When the carrier mechanism 13 moves the target chicken embryo 50 to a certain position close to the launching mechanism 12, the launching mechanism 12 accelerates the viral strain projectile 60 and injects the viral strain projectile 60 with a preset speed into the target chicken embryo 50.

[0091] When the carrying mechanism 13 moves the target chicken embryo 50 below the launching mechanism 12, the poison projectile 60 is conveyed to the launching mechanism 12 via the feeding mechanism 11. The launching mechanism 12 then fires the poison projectile 60 towards the target chicken embryo 50 and into its eggshell. It is understood that the size of the poison projectile 60 is much smaller than that of the target chicken embryo 50, for example, the size of the poison projectile 60 is less than or equal to 2 mm. Due to the small size of the poison projectile 60, its incident velocity is high, resulting in greater pressure on the eggshell. Furthermore, during the incubation process, the protein content gradually decreases, and the eggshell gradually calcifies, becoming loose and porous. Therefore, the poison projectile 60 can smoothly penetrate the eggshell, and its velocity rapidly decreases to zero due to the obstruction of the inner shell membrane, air cell membrane, and allantoic fluid. It then dissolves in the allantoic fluid and begins to grow and reproduce.

[0092] Because the launching mechanism 12 directly injects the virus pellet 60 into the eggshell of the chicken embryo, it avoids the steps required in existing technologies, such as drilling a hole with an impact head and then removing the impact head after injection. This also avoids the problem of cracks appearing in the eggshell near the injection hole when removing the impact head, thus improving the success rate of breeding. The reduced probability of cracks in the chicken embryo's eggshell also lowers breeding costs.

[0093] refer to Figure 2 In some embodiments, the toxic pellet 60 may include a capsule 61 and a toxic strain 62 disposed within the capsule 61. The capsule 61 can protect the toxic strain 62 and can dissolve in the allantoic fluid within the allantoic cavity. After the capsule 61 dissolves in the allantoic fluid, the toxic strain 62 enters the allantoic fluid and reproduces and grows.

[0094] This application provides a launching device 10 for a viral pellet 60 and a production equipment for viral chicken embryos. The launching device 10 includes a feeding mechanism 11, a launching mechanism 12, and a carrying mechanism 13. The feeding mechanism 11 is used to transport the viral pellets 60 one by one to the launching mechanism 12, and can control the delivery of the viral pellets 60 one by one to the launching mechanism 12, thereby avoiding blockage of the launching mechanism 12 when multiple viral pellets 60 enter the launching mechanism 12, and facilitating the launching mechanism 12 to control the launching speed of each viral pellet 60. The carrying mechanism 13 is used to carry the target chicken embryo 50 to be injected with the viral pellet 60, and the carrying mechanism 13 can drive the target chicken embryo 50 to move towards the launching mechanism 12, so that the target chicken embryo 50 abuts against the launching mechanism 12, thereby improving the stability of the target chicken embryo 50 during the movement. The launching mechanism 12 is located between the carrying mechanism 13 and the dropping mechanism 11. The launching mechanism 12 is used to accelerate the strain projectile 60 and shoot the strain projectile 60 with a preset speed into the eggshell of the target chicken embryo 50. This enables the strain projectile 60 to be directly shot into the eggshell of the chicken embryo under the drive of the launching mechanism 12, avoiding the use of an impact head to drill holes in the eggshell in related technologies, and avoiding the problem of cracks in the eggshell near the edge of the injection hole when the impact head is removed from the eggshell, thus improving the success rate of breeding.

[0095] refer to Figure 3 The launching device 10 may further include a storage mechanism 15, which is located on the side of the dropping mechanism 11 opposite to the launching mechanism 12. The storage mechanism 15 may be located above the dropping mechanism 11 so that the toxic pellets 60 enter the dropping mechanism 11 from above. The storage mechanism 15 may include a storage section 151 and a conveying port 152. The conveying port 152 is located between the storage section 151 and the dropping mechanism 11. The storage section 151 is used to store the toxic pellets 60 to be conveyed. The conveying port 152 communicates with the storage section 151, and the toxic pellets 60 in the storage section 151 fall into the dropping mechanism 11 through the conveying port 152.

[0096] In some examples, the storage section 151 can be a funnel-shaped structure with its larger opening facing away from the delivery port 152, allowing an operator to fill the storage section 151 with the strain pellets 60 from the larger opening. The smaller opening is connected to the delivery port 152, so that the strain pellets 60 in the storage section 151 enter the delivery port 152 from the smaller opening.

[0097] refer to Figure 3The storage mechanism 15 may further include a vibration device 153, which is disposed in the storage section 151. When the vibration device 153 is working, it drives the storage section 151 to vibrate and discharge the strain pellets 60 that are blocked in the delivery port 152. The vibration device 153 can be disposed on the outer wall surface of the storage section 151, and when the vibration device 153 is working, it can drive the storage section 151 to vibrate. If the delivery port 152 is blocked due to the accumulation of strain pellets 60, the vibration device 153 can drive the storage section 151 to vibrate, thereby eliminating the blockage at the delivery port 152 and improving the passage efficiency of the strain pellets 60 at the delivery port 152.

[0098] It is understood that the launching device 10 may also include a mounting frame, and the feeding mechanism 11, launching mechanism 12, carrying mechanism 13 and storage mechanism 15 can all be connected to the mounting frame, thereby improving the working stability of the launching device 10.

[0099] refer to Figure 3 The material feeding mechanism 11 may include a first rotating wheel 111 and a second rotating wheel 112 that cooperate with each other, the first rotating wheel 111 and the second rotating wheel 112 in a first direction (e.g. Figure 3 The first rotating wheel 111 has multiple spaced-apart first grooves 1111 on its outer periphery, which rotate with the rotation of the first rotating wheel 111. The second rotating wheel 112 has multiple spaced-apart second grooves 1121 on its outer periphery, which rotate with the rotation of the second rotating wheel 112. When the openings of the first grooves 1111 and the openings of the second grooves 1121 are in a relative state, they can form a receiving cavity 1112 for accommodating one poison pellet 60.

[0100] In a specific implementation, the first rotating wheel 111 and the second rotating wheel 112 can rotate in opposite directions, and the first groove 1111 and the second groove 1121 have sides that are far apart from each other (e.g., Figure 3 (As shown by arrow A) and the side that is close to each other, the first rotating wheel 111 and the second rotating wheel 112 are used to receive the strain projectile 60 when the first groove 1111 and the second groove 1121 are close to each other, and to discharge the strain projectile 60 toward the launching mechanism 12 when the first groove 1111 and the second groove 1121 are far apart from each other.

[0101] refer to Figure 1 The side of the first groove 1111 and the second groove 1121 that is far apart from each other faces the launching mechanism 12, so that when the first groove 1111 and the second groove 1121 are far apart from each other, the first groove 1111 and the second groove 1121 used to form the receiving cavity 1112 gradually begin to separate from the side facing the launching mechanism 12, and the toxic projectile 60 is removed from the receiving cavity 1112 from the side of the first groove 1111 and the second groove 1121 that are separated from each other.

[0102] refer to Figure 3 In some embodiments, the side of the first groove 1111 and the second groove 1121 that is close to each other faces the delivery port 152 of the storage mechanism 15, so that the side of the first groove 1111 and the second groove 1121 that is close to each other receives the strain pellet 60 delivered by the storage unit 151 through the delivery port 152, and the receiving cavity 1112 formed when the grooves of the first groove 1111 and the grooves of the second groove 1121 are close to each other accommodates a strain pellet 60.

[0103] In some embodiments, the feeding mechanism 11 may further include a first drive mechanism. If the launching device 10 has a mounting frame, the first drive mechanism can be disposed on the mounting frame so that the first rotating wheel 111 and the second rotating wheel 112 are connected to the mounting frame through the first drive mechanism. The first drive mechanism is used to drive the first rotating wheel 111 and the second rotating wheel 112 to rotate in opposite directions. In a specific implementation, the first drive mechanism can be a rotary motor and a transmission component. The rotary motor is connected to the first rotating wheel 111 and the second rotating wheel 112 through the transmission component, and the rotary motor is disposed on the mounting frame.

[0104] refer to Figure 3 In one possible implementation, the feeding mechanism 11 may further include a first conduit 113 and a second conduit 114 coaxially arranged. The first and second conduits 113 and 114 are hollow inside, allowing the passage of the toxic pellet 60. The first conduit 113 is located on the side of the first and second rotating wheels 111 and 112 facing away from the launching mechanism 12, and guides the toxic pellet 60 into the receiving cavity 1112. The side of the first conduit 113 facing the storage mechanism 15 has an enlarged hole structure 115, with the larger diameter end of the enlarged hole structure 115 facing the storage mechanism 15 to facilitate receiving the toxic pellet 60 delivered by the storage mechanism 15. The second conduit 114 is located on the side of the first and second rotating wheels 111 and 112 facing the launching mechanism 12, and guides the toxic pellet 60 that has exited the receiving cavity 1112 into the launching mechanism 12. In some embodiments, the first conduit 113 and the second conduit 114 can be connected to the mounting bracket of the launching device 10. The first conduit 113 and the second conduit 114 can be an integrally formed structure. The overall structure formed by the first conduit 113 and the second conduit 114 has through grooves on opposite sides in a first direction. The sides of the first rotating wheel 111 and the second rotating wheel 112 that are close to each other are both provided with through grooves in the overall structure of the first conduit 113 and the second conduit 114.

[0105] refer to Figure 4 The launching mechanism 12 may include a third rotating wheel 121 and a fourth rotating wheel 122 that cooperate with each other, and the third rotating wheel 121 and the fourth rotating wheel 122 are also in the first direction (e.g., Figure 4 (As shown by the middle arrow X) are arranged side by side with intervals.

[0106] refer to Figure 5 and Figure 6 The third rotating wheel 121 has a first annular groove 1211 on its outer periphery. The rotation of the third rotating wheel 121 drives the first annular groove 1211 to rotate. The fourth rotating wheel 122 has a second annular groove 1221 on its outer periphery. The rotation of the fourth rotating wheel 122 drives the second annular groove 1221 to rotate. A firing hole 1212 for accommodating a poison projectile 60 is formed on the opposite side of the first annular groove 1211 and the second annular groove 1221. The diameter of the firing hole 1212 is less than or equal to the diameter of the poison projectile 60, so that the firing hole 1212 can hold the poison projectile 60.

[0107] refer to Figure 4 and Figure 5 When the third rotating wheel 121 and the fourth rotating wheel 122 rotate in opposite directions, the first annular groove 1211 and the second annular groove 1221 have one side rotating in opposite directions (e.g., Figure 4 (As shown by arrow B) and the side facing away from the rotating direction, the side of the first annular groove 1211 and the side of the second annular groove 1221 that rotates towards each other faces the feeding mechanism 11, while the side of the first annular groove 1211 and the side of the second annular groove 1221 that rotates away from the rotating direction faces the target chicken embryo 50. In a specific implementation, during the rotation of the third rotating wheel 121 and the fourth rotating wheel 122, the side of the first annular groove 1211 and the side of the second annular groove 1221 that rotates towards each other receives the poison projectile 60 output by the feeding mechanism 11, and causes the poison projectile 60 to enter the firing hole 1212 formed between the first annular groove 1211 and the second annular groove 1221. Further, the continued rotation of the third rotating wheel 121 and the fourth rotating wheel 122 causes the poison projectile 60 in the firing hole 1212 to be fired from the side of the first annular groove 1211 and the second annular groove 1221 that rotates away from the rotating direction towards the eggshell of the target chicken embryo 50.

[0108] Understandably, the preset speed of the toxic pellet 60 provided by the launching mechanism 12 can be adjusted according to the rotation speed of the third rotor 121 and the fourth rotor 122. The preset speed of the toxic pellet 60 is optimal so that it can enter the eggshell of the target chicken embryo 50 from the side where the air cell of the target chicken embryo 50 is located and finally enter the allantoic cavity. If the preset speed is too low, the toxic pellet 60 will not be able to enter the allantoic cavity. If the preset speed is too high, the toxic pellet 60 will pass through the allantoic cavity, resulting in the toxic pellet 60 being unable to be cultured and reproduced in the allantoic cavity.

[0109] refer to Figure 6In some embodiments, anti-slip pads 124 can be provided on the groove walls of the first annular groove 1211 and the second annular groove 1221 to increase the frictional resistance between the inner peripheral walls of the toxic projectile 60 launching hole 1212 and reduce the probability of the toxic projectile 60 slipping or automatically detaching within the launching hole 1212. In specific implementations, the anti-slip pads 124 can be rubber rings fitted inside the first annular groove 1211 and the second annular groove 1221.

[0110] In some embodiments, the launching mechanism 12 may further include a second driving mechanism connected to the third rotating wheel 121 and the fourth rotating wheel 122, the second driving mechanism driving the third rotating wheel 121 and the fourth rotating wheel 122 to rotate in opposite directions. If the launching device 10 has a mounting frame, the second driving mechanism is mounted on the mounting frame, and the third rotating wheel 121 and the fourth rotating wheel 122 are mounted on the mounting frame via the second driving mechanism. In a specific implementation, the second driving mechanism may also be a rotary motor and a transmission component, the rotary motor being connected to the third rotating wheel 121 and the fourth rotating wheel 122 via the transmission component, and the rotary motor being disposed on the mounting frame.

[0111] In some embodiments, the preset speed can be adjusted according to the radius of curvature of the eggshell of the target chicken embryo 50 on the side facing the launching device 10. The larger the radius of curvature of the eggshell on that side, the lower the rotation speed of the corresponding third rotor 121 and fourth rotor 122, and the slower the launching speed of the toxic projectile 60.

[0112] refer to Figure 4 In one possible implementation, the launching device 10 may further include a guide structure 14 located on the side of the launching port 1212 of the launching mechanism 12 facing the supporting mechanism 13. The guide structure 14 has a through hole 141, through which the guide structure 14 guides the toxic seed 60 ejected from the launching port 1212 to the target chicken embryo 50. In some embodiments, if the launching device 10 has a mounting bracket, the guide structure 14 can be mounted on the mounting bracket, and the through hole 141 of the guide structure 14 can be coaxially arranged with the launching port 1212. By providing the guide structure 14, the launching direction of the toxic seed 60 launched by the launching device 10 can be guided and adjusted so that the toxic seed 60 is launched toward the eggshell of the target chicken embryo 50.

[0113] refer to Figure 4 The launching device 10 may also include a fixing plate 144, which is disposed on the mounting frame so that the guide structure 14 is mounted on the mounting frame via the fixing plate 144. The fixing plate 144 is disposed on the outer periphery of the guide structure 14. By setting the fixing plate 144, the stability of the guide structure 14 can be improved, and the path of the toxic projectile 60 can be deviated due to the shaking of the guide structure 14.

[0114] refer to Figure 4The launching device 10 may further include a shock absorber 142, which is disposed on the side of the guide structure 14 facing the support mechanism 13. The shock absorber 142 communicates with the through hole 141 and covers the side of the target chicken embryo 50 whose eggshell faces the launching mechanism 12. By covering the target chicken embryo 50 with the shock absorber 142, the probability of the toxic projectile 60 vibrating when it enters the target chicken embryo 50 can be reduced. The launching device 10 may further include a buffer pad 143, which covers the inner surface of the shock absorber 142 so that the target chicken embryo 50 abuts against the shock absorber 142 through the buffer pad 143. By providing the shock absorber 142 and covering the side of the shock absorber 142 facing the target chicken embryo 50 with the buffer pad 143, at least part of the vibration generated by the toxic projectile 60 when it passes through the eggshell of the target chicken embryo 50 can be absorbed.

[0115] refer to Figure 7 and Figure 8 The supporting mechanism 13 may include a drive unit, a support assembly 131, and a support structure 132. The drive unit is connected to the support assembly 131, and the support structure 132 is disposed on the support assembly 131. The support structure 132 has a support groove 1321 on the side facing the launching mechanism 12, which is used to support the target chicken embryo 50. The drive unit drives the support structure 132 to move towards the launching mechanism 12 by driving the support assembly 131. In some embodiments, by placing the target chicken embryo 50 in the support groove 1321, the stability of the target chicken embryo 50 during its movement towards the launching mechanism 12 can be improved. In a specific implementation, the drive unit may be a linear motor and a transmission rod, with the linear motor connected to the support assembly 131 via the transmission rod.

[0116] refer to Figure 7 In one possible implementation, the supporting structure 132 may include multiple supporting arms 1322. The supporting arms 1322 are disposed at one end of the supporting assembly 131 facing the launching mechanism 12. The multiple supporting arms 1322 surround the outer periphery of the supporting assembly 131 and form supporting grooves 1321. The number of supporting arms 1322 can be three, four, five, or even more; for example, the number of supporting arms 1322 can be four. The supporting arms 1322 can be arc-shaped to match the curvature of the eggshell of the target chicken embryo 50, thereby better conforming to the surface of the eggshell of the target chicken embryo 50.

[0117] refer to Figure 8The support assembly 131 may include a first support rod 1311, a second support rod 1312, and a buffer 1313. One end of the first support rod 1311 is connected to the support structure 132. The side of the first support rod 1311 facing away from the support structure 132 has a receiving groove 1314. The buffer 1313 is disposed in the receiving groove 1314, and a portion of the second support rod 1312 is located in the receiving groove 1314. The second support rod 1312 is connected to the first support rod 1311 through the buffer 1313. The second support is connected to a drive unit. The drive unit drives the first support rod 1311 and the support structure 132 toward the launching mechanism 12 by driving the second support rod 1312. The support assembly 131 includes a first support rod 1311, a second support rod 1312, and a buffer 1313, so that the first support rod 1311 and the second support rod 1312 are connected through the buffer 1313. This can absorb the vibration generated when the toxic projectile 60 passes through the eggshell of the target chicken embryo 50, improve the stability of the toxic projectile 60 when it enters the target chicken embryo 50, and improve the working stability of the launching device 10.

[0118] In some embodiments, the buffer 1313 can be a shock-absorbing spring, with one end connected to the bottom wall of the receiving groove 1314 and the other end connected to the end of the second support rod 1312 facing into the receiving groove 1314. In other embodiments, in order to better absorb the vibration generated when the toxin projectile 60 passes through the eggshell of the target chicken embryo 50, the shock-absorbing spring can be connected to a damping structure to form a damping spring shock absorber, thereby providing a better shock absorption effect.

[0119] In some other embodiments, the buffer 1313 may also be a buffer cotton or a buffer pad. If the buffer 1313 is a buffer cotton, the buffer cotton is disposed in the receiving groove 1314, and the first support rod 1311 is connected to the second support rod 1312 through the buffer cotton.

[0120] refer to Figure 9 The launching device 10 may further include a camera mechanism 16 and a control mechanism. Both the camera mechanism 16 and the launching mechanism 12 are electrically connected to the control mechanism. The camera mechanism 16 acquires a three-dimensional image of the eggshell of the target chicken embryo 50 facing the launching mechanism 12 and sends the acquired three-dimensional image to the control mechanism. The control mechanism calculates the radius of curvature of the surface of the eggshell of the target chicken embryo 50 facing the launching mechanism 12 based on the three-dimensional image and adjusts the launching speed of the poison projectile 60 launched by the launching mechanism 12 according to the radius of curvature. The launching speed of the poison projectile 60 of the launching mechanism 12 increases as the radius of curvature decreases. By connecting the camera mechanism 16, the launching mechanism 12, and the control mechanism, the launching device 10 can set a preset speed for the corresponding poison projectile 60 according to different eggshell curvature radii.

[0121] If the launching mechanism 12 includes a third rotating wheel 121, a fourth rotating wheel 122 and a second driving mechanism, the control mechanism can be connected to the second driving mechanism and adjust the rotation speed of the third rotating wheel 121 and the fourth rotating wheel 122 by controlling the second driving mechanism, thereby adjusting the preset speed of the poison projectile 60.

[0122] In other embodiments, the control mechanism can also be electrically connected to the unloading mechanism 11, the carrying mechanism 13, and the storage mechanism 15. The control mechanism can control the carrying mechanism 13 to move toward or away from the launching mechanism 12, and can also control the operation and stop of the unloading mechanism 11. This further improves the automation level of the launching device 10 and enhances its practicality.

[0123] refer to Figure 9 This application embodiment also provides a production device for chicken embryos containing a viral strain. The production device may include a conveying mechanism 20, a support platform 30, a screening mechanism 40, and multiple launching devices 10 for viral pellets 60 as described above. The support platform 30 is disposed on the conveying mechanism 20 and has multiple spaced-apart support seats 31. Each support seat 31 is used to place a target chicken embryo 50 to be injected with a viral pellet 60. Each launching device 10 launches a viral pellet 60 at a target chicken embryo 50 on a support seat 31. The conveying mechanism 20 drives the support platform 30 to move, moving the injected target chicken embryo 50 to the screening mechanism 40. The screening mechanism 40 is used to screen out target chicken embryos 50 that have developed cracks.

[0124] In some embodiments, the conveying mechanism 20 can be two spaced-apart conveyor belts, and the carrier platform 30 can be placed between the two conveyor belts and move along the extension direction of the conveyor belts. The production equipment can be divided into a first region 21, a second region 22, and a third region 23 in the conveying direction of the conveying mechanism 20. When the carrier platform 30 is located in the first region 21, the operator places multiple target egg embryos in each carrier seat 31 of the carrier platform 30. Then, the conveying mechanism 20 conveys the carrier platform 30 containing the target chicken embryos 50 to the second region 22. The second region 22 is the area where the launching device 10 injects the toxin pellet 60 into the target chicken embryos 50. When the target chicken embryos 50 on the carrier platform 30 move to the second region 22, the launching device 10 launches the toxin pellet 60 into the target chicken embryos 50. Then, the conveying mechanism 20 further moves the carrier platform 30 and the target chicken embryos 50 after injecting the toxin pellet 60 to the third region 23. The screening mechanism 40 is located in the third region 23 and can screen the target chicken embryos 50 that have cracked.

[0125] In some examples, the screening mechanism 40 may include a black box, a light source, a camera, and an image analysis system. The light source can provide illumination for the target chicken embryo 50 inside the black box, and the camera can capture images of the target chicken embryo 50 inside the black box and transmit them to the image analysis system so that the image analysis system can analyze the camera's image results and screen out the target chicken embryo 50 with cracks.

[0126] By using the above-mentioned strain chicken embryo production equipment and the above-mentioned strain projectile 60 launching device 10 in the production equipment, the probability of the eggshell of the target chicken embryo 50 cracking can be reduced, the breeding cost of the strain chicken embryo can be reduced, and the injection efficiency of the strain can be improved.

[0127] refer to Figure 10 The launching device 10 may include a launching mechanism 12 and a carrying mechanism 13. When the conveying mechanism 20 conveys the carrying platform 30 to the second region 22 of the launching device 10, the launching mechanism 12 is located above the carrying seat 31, and the carrying mechanism 13 is located below the carrying seat 31. The carrying seat 31 has a placement groove 311 for placing the target chicken embryo 50. The bottom of the placement groove 311 has a connecting opening. The carrying mechanism 13 passes through the connecting opening into the placement groove 311 to support the target chicken embryo 50 in the placement groove 311 and supports the target chicken embryo 50 to move toward the launching mechanism 12.

[0128] refer to Figure 8 and Figure 10 It is understood that if the support mechanism 13 has a drive unit, a support component 131 and a support mechanism, the drive unit can drive the support component 131 and the support structure 132 to move upward from below the support seat 31 through the communication port, and support the target chicken embryo 50 in the placement slot 311 through the support structure 132.

[0129] In some embodiments, the wall of the placement groove 311 within the support 31 can be formed by a plurality of arc-shaped sidewalls 312, with intervals between the arc-shaped sidewalls 312, which can communicate with the communication port. If the support structure 132 has a plurality of support arms 1322, the number of intervals can be the same as the number of support arms 1322, so that when the support structure 132 passes through the communication port, each support arm 1322 can pass through one interval.

[0130] In some embodiments, the launching device 10 may further include a camera mechanism 16 and a control mechanism. The camera mechanism 16 is electrically connected to the control mechanism, and the control mechanism is also electrically connected to the launching mechanism 12 in the launching device 10. The camera mechanism 16 can be positioned in the first region 21 to acquire a three-dimensional image of the side of the target chicken embryo 50 on the support 31 facing away from the support platform 30. The control mechanism can calculate the radius of curvature of the area on the eggshell being photographed based on the three-dimensional image of the eggshell of the target chicken embryo 50 acquired by the camera mechanism 16, and the control mechanism can adjust the preset speed at which the launching device 10 launches the strain projectile 60 according to the radius of curvature of each eggshell.
