Description

Technical Field

[0001] The invention relates to the technical field of vaccine preparation, and in particular to a chicken embryo allantoic fluid collection device for trial production of a multi-link inactivated vaccine for poultry. Background Art

[0002] At present, the main diseases affecting chickens are Newcastle disease, avian influenza and infectious bursal disease. In addition, FADV is widely distributed throughout the world and is susceptible to poultry of different ages. Among them, group I type 4 FADV-4 can mainly cause "chicken hepatitis-pericardial effusion syndrome" in chickens, which is a viral infectious disease caused by avian adenovirus type 4 that mainly harms broiler chickens. The disease first occurred in Ankara, Pakistan in 1987, and then became popular in Asia, Europe and South America. Therefore, prevention should be the main focus for chicken diseases, and in view of the current domestic breeding and morbidity, combined vaccines can better prevent and control the occurrence of chicken diseases, so the research and development of multi-inactivated vaccines for Newcastle disease, avian influenza (H9 subtype), infectious bursal disease, and avian adenovirus (group I, type 4) is imperative.

[0003] Certain viruses that infect poultry can reproduce well in chicken embryos, such as avian influenza virus and Newcastle disease virus. Therefore, the principle that viruses can grow and reproduce in chicken embryos can be used to conduct in-depth research on such viruses. Toxic allantoic fluid is also the basic raw material for certain biological products. In the process of researching and trial-producing poultry multi-component inactivated vaccines, a large number of chicken embryos are needed to prepare and identify seed viruses for production, and the allantoic fluid needs to be collected.

[0004] Traditional collection methods mostly rely on manually breaking the eggshell first. After opening the air chamber of the chicken embryo, the eggshell membrane needs to be torn off with tweezers, and the chorioallantoic membrane needs to be gently clamped. Then, the chicken embryo allantoic fluid can be extracted with a Pasteur pipette. This results in complicated pre-preparation procedures before extracting the allantoic fluid, which is inconvenient for handling the chicken embryo. At the same time, the broken eggshell is likely to fall onto the chorioallantoic membrane during shelling, which will contaminate the allantoic fluid when the chicken embryo allantoic fluid is extracted. Summary of the invention

[0042] Embodiment 2

[0043] See also Figure 1 , Figure 6 and Figure 7 As shown, on the basis of the first embodiment, a shell breaking mechanism 4 is arranged on one side of the top of the support frame 1, and the shell breaking mechanism 4 is used to break the eggshell on the top of the chicken embryo, so as to facilitate the subsequent peeling of the eggshell at the broken position, and the shell breaking mechanism 4 includes a connecting seat 401, and a fixing plate 402 is fixedly connected to the top of the connecting seat 401, and the fixing plate 402 is used to fix the motor frame 403, and the front surface of the fixing plate 402 is fixedly connected to the motor frame 403, and the motor frame 403 is used to fix the transmission motor 1 404, and the inner side of the motor frame 403 is fixedly connected to the transmission motor 1 404, and the transmission The motor 404 is used to drive the turntable 405 to rotate. The outer wall of the output shaft at the front end of the transmission motor 404 is locked and connected to the turntable 405 through a coupling. The turntable 405 is used to drive the connector 406 to move. The front surface of the turntable 405 is rotatably connected to the connector 406. The connector 406 is used to connect the turntable 405 with the vertical rod 407. The bottom inner side of the connector 406 is rotatably connected to the vertical rod 407. The vertical rod 407 is used to fix the top plate 410 and the knocking head 411. The top of the front surface of the connecting seat 401 is fixedly connected to a cross bar. 408, the cross bar 408 is used to fix the sleeve 409, the front end of the cross bar 408 is fixedly connected with the sleeve 409, the sleeve 409 is used to limit the movement trajectory of the vertical rod 407, so that the vertical rod 407 maintains vertical movement, the outer wall bottom of the vertical rod 407 is fixedly connected with a top plate 410, the top plate 410 is used to fix the top of the spring rod 412, the bottom end of the vertical rod 407 is fixedly connected with a knocking head 411, the knocking head 411 is used to knock the eggshell on the top of the chicken embryo, the bottom four corners of the top plate 410 are fixedly connected with spring rods 412, the spring rods 412 are fixedly connected to the top of the top plate 410, and the spring rods 412 are fixedly connected to the bottom of the top plate 410. 412 is used to fix the buckle plate 413. The bottom of the multiple spring rods 412 is fixed with the buckle plate 413. The buckle plate 413 can be buckled to the top of the slot block 3051 and limit the movement stroke of the knocking head 411 when the knocking head 411 knocks the eggshell to prevent the knocking head 411 from directly smashing the entire chicken embryo.

[0044] In the present embodiment, preferably, the top of the connecting head 406 is eccentrically arranged on the front surface of the turntable 405. Since the connecting head 406 is eccentrically arranged on the front surface of the turntable 405, when the turntable 405 rotates, the vertical rod 407 can be driven to perform vertical reciprocating motion through the cooperation between the connecting head 406, the vertical rod 407 and the sleeve 409, thereby driving the knocking head 411 to knock on the eggshell at the top of the chicken embryo. A cavity is preset at the top center of the buckle plate 413, which is interlocked with the outer wall of the knocking head 411. The bottom end of the outer wall of the knocking head 411 extends to the inner top of the buckle plate 413, and the knocking head 411 can slide inside the buckle plate 413.

[0045] In summary, before collecting the allantoic fluid of the chicken embryo, the eggshell on the top of the allantoic cavity of the chicken embryo needs to be peeled off before the allantoic fluid can be collected. However, before peeling the eggshell, the eggshell to be peeled off needs to be broken to facilitate the subsequent peeling of the eggshell. When the clamping member 305 holding the chicken embryo moves to the bottom end of the shell breaking mechanism 4, the transmission motor 1 404 starts to work, and the transmission motor 1 404 can drive the turntable 405 to rotate, thereby driving the connector 406 eccentrically connected to its front surface to move. When the connector 406 moves, it will drive the vertical rod 407 connected to the inner side of its bottom to rotate. The vertical rod 407 can move back and forth, thereby driving the striking head 411 to move back and forth together through the vertical rod 407. The cross bar 408 and the sleeve 409 cooperate with each other to limit the movement trajectory of the vertical rod 407, so that the vertical rod 407 can always maintain vertical movement. At the same time, when the striking head 411 strikes the eggshell at the top of the chicken embryo, the buckle plate 413 will be buckled to the top of the chicken embryo, and while protecting the outer wall of the chicken embryo eggshell, it can also limit the movement stroke of the striking head 411 to avoid the striking head 411 moving too much and directly breaking the entire eggshell of the chicken embryo, thereby protecting the chicken embryo.

The middle sections of both sides of the discharge trough 501 are fixedly connected with cross plates 506, and the cross plates 506 are used to connect the spring rod 2 507 and the discharge trough 501 together. The bottom ends of the two cross plates 506 are fixedly connected with spring rod 2 507, and the spring rod 2 507 is used to support the discharge trough 501. The bottom of the discharge trough 501 is provided with a storage box 508, and the storage box 508 is used to collect the peeled eggshells for subsequent centralized processing. The top front end of the storage box 508 is fixedly connected with a handle 509 for driving the storage box 508 to move. The bottom of the spring rod 2 507 is fixedly connected to the front end top of the support frame 1, and the storage box 508 is slidably connected to the front end top of the support frame 1. The shelling mechanism 5 and the shell breaking mechanism 4 are located on the same central axis.

[0048] In the present embodiment, preferably, the output shaft on the side of the transmission motor 2 504 is fixedly connected to one side of the shelling roller 502 located at the rear end of the top inner side of the discharge trough 501, and the other side of the shelling roller 502 located at the rear end of the top inner side of the discharge trough 501 is fixedly connected to the side of the toothed disk 505 located at the rear end of the other side inside the frame 503, and the side of the toothed disk 505 located at the front end of the other side inside the frame 503 is fixedly connected to the side of the shelling roller 502 located at the front end of the top inner side of the discharge trough 501, and the two gears are meshed with each other, so when one of the shelling rollers 502 rotates, the other shelling roller 502 will rotate in the opposite direction.

[0049] In the present embodiment, preferably, the outer walls of the two shelling rollers 502 are wrapped with a rubber skin with a flexible texture on one side, and a hollow hose made of PVC is spirally arranged on the outer wall of the rubber skin. The spiral directions of the hollow hoses on the outer walls of the two shelling rollers 502 are completely opposite. The rubber skin can protect the chicken embryo to avoid damage to the chorioallantoic membrane of the chicken embryo during shelling, which would cause the premature outflow of the allantoic fluid. The spirally arranged hollow hose can enhance the peeling effect of the shelling roller 502 on the eggshell.

[0050] In summary, after the eggshell on the top of the chicken embryo is broken, the broken chicken embryo will be transported to the top of the shelling mechanism 5 through the overall work of the conveying mechanism 3. When the chicken embryo passes through the top of the shelling roller 502 at the broken shell point, the shelling roller 502 will peel off the broken eggshell from the chicken embryo. And because the chicken embryo is in a flipped state at this time, it can also prevent eggshell residues from falling onto the chorion membrane when it is shelled.

[0051] Embodiment 4

The upper surface of the small conveyor 602 is parallel to the upper surface of the chain conveyor belt 302. The electric push rod 604 is fixedly connected to the inner top of the support frame 1.

[0053] In summary, when the chicken embryo that needs to collect the allantoic fluid has undergone a series of pre-treatments and can directly collect the allantoic fluid, the clamping member 305 holding the chicken embryo will also be transported and moved to the front end of the electric push rod 604 in the discharge mechanism 6 through the chain conveyor belt 302. At this time, the electric push rod 604 starts to work, and the clamping member 305 can be pushed out of the groove plate 304 through the electric push rod 604, and the clamping member 305 is pushed to the top of the small conveyor. Through the mutual cooperation between multiple baffles 603, the bottom end of the outer wall of the clamping member 305 can be enclosed to prevent the clamping member 305 from falling off from the top of the small conveyor 602 during the transportation process, so as to facilitate the discharge of the processed chicken embryo, thereby facilitating the subsequent collection of the chicken embryo allantoic fluid.

[0054] Embodiment 5

[0055] See also Figure 1-Figure 9 As shown, the present embodiment is obtained by combining the first to fourth embodiments. When it is necessary to extract the allantoic fluid of the chicken embryo, the chicken embryo from which the allantoic fluid needs to be extracted is first placed inside the clamping member 305. Through the cooperation of the clamping member 305, the chicken embryo placed in the clamping member 305 can be clamped and fixed. After the chicken embryo is fixed, the clamping member 305 is clamped to the inside of the groove plate 304 provided on the outer wall of the chain conveyor belt 302. Through the cooperation of the stepping motor 303 and the driving wheel 301, the clamped groove plate 304 can be driven to move. The clamping member 305 at the top of the conveyor belt 302 moves, so that the chicken embryo can be transported to the bottom of the shell breaking mechanism 4 and the top of the shelling mechanism 5 in sequence. Through the operation of the shell breaking mechanism 4 and the shelling mechanism 5, the chicken embryo can be shelled first and then the eggshell at the eggshell of the broken chicken embryo can be peeled off. Finally, through the operation of the discharging mechanism 6, the processed chicken embryo is taken out from the chain conveyor belt 302, which is convenient for the subsequent collection of the chicken embryo allantoic fluid and speeds up the pre-treatment speed of the chicken embryo before extracting the chicken embryo allantoic fluid.
