[0022] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0023] Please also refer to Figure 1 and Figure 2 The present invention now provides a description of the allantoic fluid harvesting device for chicken embryos. The device comprises a device housing 1, a liquid collecting tank 2, a chicken embryo tray 3, a chicken embryo cutter 4, an allantoic fluid collecting tube 5, and a disinfectant nozzle 6. The device housing 1 comprises an inner cavity with a bottom opening. The liquid collecting tank 2 is disposed below the device housing 1 and faces the lower opening of the inner cavity. The chicken embryo tray 3 is disposed below the device housing 1 and is provided with an embryo balancing hole 310. The chicken embryo cutter 4 is disposed in the inner cavity and is located above the chicken embryo tray 3. The chicken embryo cutter 4 is movable in a predetermined horizontal direction. The allantoic fluid collecting tube 5 is disposed at the top of the inner cavity. The disinfectant nozzle 6 is disposed at the top of the inner cavity and is connected to the top wall of the inner cavity in a manner that allows it to be raised and lowered. The disinfectant nozzle 6 is also connected to a disinfectant preparation tank 26.

[0024] In the present embodiment, the disinfection nozzle 6 is a spray ball to expand the spray range of the disinfection nozzle 6. The disinfectant can be chlorhexidine, or other verified disinfectants.

[0025] In this embodiment, the allantoic fluid collecting tube 5 and the disinfection nozzle 6 are staggered and distributed on the horizontal plane without interfering with each other.

[0026] In this embodiment, the inner diameter of the chicken embryo balancing hole 310 is smaller than the outer diameter of the chicken embryo, thereby being able to support the chicken embryo and limit the position of the chicken embryo.

[0027] The chicken embryo allantoic fluid harvesting device provided in this embodiment has the following beneficial effects compared with the prior art: 1. If it is necessary to extract allantoic fluid, it is necessary to place chicken embryos one by one in the chicken embryo balance hole 310 on the chicken embryo tray 3 to ensure the stability of the chicken embryo position, then utilize the chicken embryo cutter 4 to move along the preset horizontal direction to cut the chicken embryo, make a gap at the top of the chicken embryo, and after cutting, the chicken embryo cutter 4 moves in the opposite direction to reset; then utilize the allantoic fluid collecting tube 5 to stretch into the gap, draw the allantoic fluid in the chicken embryo, until extraction is complete. The present application integrates the cutting of chicken embryo and the extraction of allantoic fluid into one station, and the chicken embryo cutter 4 does not need to move the chicken embryo tray 3 after cutting, and can directly utilize the allantoic fluid collecting tube 5 to extract allantoic fluid, avoid transferring the chicken embryo opened after cutting between different stations, cause the problem of allantoic fluid pollution, and improve the reliability of use.

[0028] 2. If disinfection is needed, first the disinfectant nozzle 6 is placed in a higher position, spraying disinfectant at a high position, spraying the top of the equipment housing 1 and utilizing the allantoic fluid collecting tube 5 for disinfection; subsequently, the disinfectant nozzle 6 is controlled to move downward, placed in a lower position, and spraying the bottom of the equipment housing 1, the chicken embryo tray 3, and the chicken embryo cutter 4 at a low position for disinfection. By moving the disinfectant nozzle 6 up and down, the equipment housing 1 and each internal component can be fully sprayed, while avoiding the manual disinfection operation of personnel, thereby avoiding the problem of inadequate disinfection and ensuring the reliability of disinfection. The disinfectant wastewater flows into the liquid collecting tank 2 below for unified collection and treatment to avoid secondary contamination.

[0029] In some embodiments, see Figures 7 to 9 The chicken embryo allantoic fluid harvesting device also includes a positioning baffle 29 and a lifting mechanism 30. The positioning baffle 29 is provided with a chicken embryo positioning hole 2910. The positioning baffle 29 is arranged at the bottom of the inner cavity of the shell and is located between the chicken embryo tray 3 and the chicken embryo cutter 4; the lifting mechanism 30 is located below the chicken embryo tray 3 and can lift the chicken embryo placed in the chicken embryo balance hole 310 upward until the top of the chicken embryo contacts the edge of the chicken embryo positioning hole 2910, so that the chicken embryo extends upward from the positioning baffle 29. Figure 8 and Figure 9In the figure, the chick embryo is represented by a dotted line. Figure 8 The figure shows the initial state of the chicken embryo tray 3, the positioning baffle 29 and the lifting mechanism 30. Figure 9 The figure shows a state where the lifting mechanism 30 lifts the chicken embryo and causes the top of the chicken embryo to extend out of the positioning baffle 29 .

[0030] Only rely on chicken embryo tray 3 pairs of chicken embryos to carry out the poor effect of positioning support, be pushed to easily after contacting with chicken embryo cutter 4, and, also easily occur because of the chicken embryo height inconsistency, cause the opening size that chicken embryo cutter 4 cuts out on each chicken embryo to be inconsistent, directly affect follow-up extraction operation.Therefore, by lifting mechanism 30, each chicken embryo is upwards lifted respectively, it is stretched into chicken embryo locating hole 2910, after the top of chicken embryo contacts with the edge of chicken embryo locating hole 2910, chicken embryo upwards stretches out locating baffle 29, and the height that each chicken embryo stretches out locating baffle 29 is basically identical.In this way, locate the top of chicken embryo by locating baffle 29 pairs of chicken embryos, locate the bottom of 30 pairs of chicken embryos by lifting mechanism, chicken embryo position is stable when guaranteeing cutting, simultaneously, can also guarantee that the opening size that chicken embryo cutter 4 manufactures on each chicken embryo is basically identical, before allantoic fluid collecting tube 5 has collected, chicken embryo remains fixed on the state between locating baffle 29 and the lifting mechanism 30.

[0031] In some specific embodiments of the lifting mechanism 30, the lifting mechanism 30 includes a base 3010 and a plurality of lifting units 3020, such as Figure 8 and Figure 9 As shown, the lifting unit 3020 corresponds one to one with the chicken embryo balance hole 310 on the chicken embryo tray 3. The lifting unit 3020 includes a lifting driver 3021 and a lifting seat 3022, wherein the lifting driver 3021 is located on the base 3010, and the lifting seat 3022 is located at the lifting end of the lifting driver 3021; a lifting groove 3023 is provided in the lifting seat 3022, and the lifting groove 3023 is a spherical groove, which can fit with the bottom of the chicken embryo. After the chicken embryo contacts the edge of the chicken embryo positioning hole 2910, the chicken embryo can deflect in the lifting groove 3023, perform posture correction, and make the chicken embryo achieve a standard upright state, ensure the consistency of the incision position of the chicken embryo cutter 4 on each chicken embryo, so as to accurately extract the allantoic fluid in each chicken embryo.

[0032] Optionally, the implementation of the lifting driver 3021 includes but is not limited to a lifting cylinder, a lifting hydraulic cylinder, a lifting electric push rod, etc.

[0033] Optionally, a pressure sensor is provided between the lifting seat 3022 and the lifting end of the lifting driver 3021. The pressure sensor is communicatively connected to the lifting driver 3021. The pressure sensor can sense the pressure on the chicken embryo in real time. After the chicken embryo contacts the edge of the chicken embryo positioning hole 2910, if the pressure sensor senses that the pressure value reaches a preset high value, the lifting driver 3021 is controlled to stop the lifting action to avoid continuous lifting causing excessive pressure on the chicken embryo, which may lead to the problem of rupture of the chicken embryo shell.

[0034] It should be noted that the communication connection in this embodiment can be a wired connection or a wireless connection (such as WiFi, Bluetooth, etc.).

[0035] In some embodiments, see Figure 2 The chicken embryo allantoic fluid harvesting device also includes a disinfection connecting outer tube 7, a disinfection connecting inner tube 8, and a disinfection lifting control mechanism 9. The disinfection connecting outer tube 7 is connected between the upper wall plate 110 of the device housing 1 and the disinfection liquid configuration tank 26; the disinfection connecting inner tube 8 is connected between the upper wall plate 110 of the device housing 1 and the disinfection nozzle 6 and is communicated with the disinfection connecting outer tube 7. The disinfection connecting inner tube 8 is a flexible tube; and the disinfection lifting control mechanism 9 is arranged between the upper wall plate 110 of the device housing 1 and the disinfection nozzle 6 to drive the disinfection nozzle 6 to rise and fall. The disinfectant in the disinfection liquid configuration tank 26 can pass through the disinfection connecting outer tube 7 and the disinfection connecting inner tube 8 in sequence and then flow into the disinfection nozzle 6. By providing a flexible disinfection connecting inner tube 8, it can adaptively deform during the up and down movement of the disinfection nozzle 6, thereby effectively improving the reliability of the liquid supply to the disinfection nozzle 6.

[0036] Optionally, the disinfection connection inner tube 8 is a silicone tube, and the distance between the disinfection nozzle 6 and the liquid outlet end of the disinfection connection outer tube 7 when the disinfection nozzle 6 is at the bottom is D. The length of the disinfection connection inner tube 8 is not less than D, and it adapts to the lifting action of the disinfection nozzle 6 by bending or stretching itself. In other embodiments, the disinfection connection inner tube 8 is a corrugated tube, which adapts to the lifting action of the disinfection nozzle 6 by folding, contracting or stretching itself, such as Figure 5 shown.

[0037] In some embodiments, see Figure 1 and Figure 2 A disinfection liquid inlet pump 10 is provided on the disinfection connection outer tube 7, which can provide power to guide the disinfectant to the disinfection nozzle 6 and cooperate with the disinfection nozzle 6 to generate spraying pressure. The implementation of the disinfection liquid inlet pump 10 includes but is not limited to a gear pump, a plunger pump, etc.

[0038] In some embodiments, see Figure 2The chick embryo allantoic fluid harvesting device also includes a disinfection liquid dispensing pipe 11, which extends horizontally and is a rigid tube fixed to the top of the inner cavity of the housing. Multiple disinfection connecting inner tubes 8 are provided, each connected to the liquid outlet of the disinfection connecting outer tube 7 and to the liquid inlet of each disinfection connecting inner tube 8. A disinfection lifting control mechanism 9 is connected between the disinfection nozzle 6 and the disinfection liquid dispensing pipe 11. The disinfection liquid dispensing pipe 11 can be connected to multiple disinfection connecting inner tubes 8 simultaneously, thereby achieving liquid supply to multiple disinfection connecting inner tubes 8 while only one disinfection connecting outer tube 7 is provided. By rationally arranging the configuration of the disinfection liquid dispensing pipe 11 and the position of the disinfection connecting inner tube 8, multi-point spray disinfection is achieved, improving the comprehensiveness of the disinfectant spray coverage. In addition, since the disinfection liquid dispensing pipe 11 is a rigid tube, it also provides an installation base for the disinfection lifting control mechanism 9, which does not need to be connected to the upper wall plate 110, further simplifying the structure of the equipment housing 1.

[0039] Optionally, a hanging ring for fixing the disinfection liquid dispensing tube 11 is provided on the upper wall plate 110 of the equipment housing 1. The hanging ring has a simple structure and is convenient for setting liquid.

[0040] Optionally, the disinfection liquid dispensing tube 11 can be a straight tube (such as Figure 2 As shown), it can also be an I-shaped or grid-shaped pipe fitting, which is related to the arrangement of the disinfection nozzle 6 and is not limited to the material of the disinfection liquid dispensing pipe 11, including but not limited to PVC material.

[0041] Based on the above embodiments, see Figure 5 The disinfection lifting control mechanism 9 includes a lifting driver, a driving gear 910 and a lifting rack 920; the lifting rack 920 extends in the up and down directions, the upper end of which is slidably adapted to the disinfection liquid dispensing tube 11, and the lower end is fixedly connected to the disinfection nozzle 6; the lifting driver is fixed to the disinfection liquid dispensing tube 11, the driving gear 910 is coaxially connected to the output shaft of the lifting driver, and the driving gear 910 is meshed with the lifting rack 920. In this embodiment, the meshing transmission mode of the driving gear 910 and the lifting rack 920 is more stable and reliable, and can also realize continuous adjustment of the height of the disinfection nozzle 6. The overall structure of the disinfection lifting control mechanism 9 is simple and the cost of use is also low. Among them, the implementation methods of the lifting driver include but are not limited to servo motors, variable frequency motors, etc.

[0042] Optionally, in order to improve the stability of the lifting action of the lifting rack 920 , a guide sleeve 930 is provided on the lower surface of the upper wall plate 110 of the equipment housing 1 , and the upper portion of the lifting rack 920 is slidably inserted into the guide sleeve 930 .

[0043] In some embodiments, see Figure 1 and Figure 2A drain port 210 is provided at the bottom of the liquid collecting tank 2. The drain port 210 is connected to the waste liquid collection tank 13 through a drain pipe 12. A drain pump 14 is provided on the drain pipe 12. By providing the waste liquid collection tank 13, waste liquid can be introduced into the waste liquid collection tank 13 when the liquid level in the liquid collecting tank 2 is high, thereby preventing the waste liquid in the liquid collecting tank 2 from overflowing. Optionally, a liquid level sensor is provided in the liquid collecting tank 2 to accurately sense the liquid level. The liquid level sensor is in communication with the drain pump 14 to start the drain pump 14 to drain the liquid after detecting that the liquid level is higher than a preset high value.

[0044] In some embodiments, see Figure 1 and Figure 2 A transmission channel 15 is formed between the device housing 1 and the liquid collecting tank 2. The front and rear ends of the transmission channel 15 are open. A transmission track 16 extending front and back is provided in the transmission channel 15. The transmission track 16 can drive the chicken embryo tray 3 to move into the inner cavity of the housing in the front and rear directions, or move out of the inner cavity of the housing. By providing the transmission track 16, the operations of placing the chicken embryo tray 3 and placing the chicken embryos on the chicken embryo tray 3 can be completed outside the transmission channel 15. These operations do not need to be performed inside the device housing 1, which can make the device housing 1 more compact and the overall space occupied by the device smaller. After the extraction operation is completed, the chicken embryo tray 3 can be promptly removed from the device housing 1 so that the next batch of chicken embryos can be promptly delivered to the tray, thereby improving the continuity of the operation.

[0045] Based on the above embodiments, see Figure 1 The left wall panel 120 of the equipment housing 1 extends downward and is sealed to the upper end of the left wall of the liquid collecting tank 2; the right wall panel 130 of the equipment housing 1 extends downward and is sealed to the upper end of the right wall of the liquid collecting tank 2. In this way, the two sides of the transmission channel 15 are relatively sealed, which can effectively avoid the problem of splashing of disinfectant waste liquid during the disinfection process. In addition, the wall panels on both sides of the transmission channel 15 can also play a role in limiting and shielding the chicken embryo tray 3 to a certain extent, which is conducive to improving the stability of the movement of the chicken embryo tray 3.

[0046] In some embodiments, see Figure 3The chicken embryo allantoic fluid harvesting device also includes a cutter drive mechanism 17. The telescopic end of the cutter drive mechanism 17 can drive the chicken embryo cutter 4 to move in the left and right directions. In order to avoid interference with the conveying track 16, the left and right directions are preset horizontal directions. Optionally, the implementation methods of the cutter drive mechanism 17 include but are not limited to electric push rods, telescopic cylinders, telescopic hydraulic cylinders, etc. Among them, the main body of the cutter drive mechanism 17 is arranged outside the device housing 1, and its telescopic end slides through the device housing 1, and the telescopic movement direction is parallel to the preset horizontal direction. The device housing 1 is provided with a through-hole for the telescopic end of the cutter drive mechanism 17 to slide through. A sealing sleeve is provided in the through-hole to ensure the sealing between the telescopic end of the cutter drive mechanism 17 and the device housing 1. This embodiment exemplarily shows a solution of setting the cutter drive mechanism 17 on the right wall panel 130.

[0047] In some embodiments, see Figure 3 The chicken embryo cutter 4 includes a cutter body 410 and a connecting side plate 420. The connecting side plate 420 is connected to the telescopic end of the cutter drive mechanism 17, and the plate surface is perpendicular to the left and right directions; the cutter body 410 is connected to the bottom edge of the connecting side plate 420, and a receiving groove 440 is formed at the bottom of the connecting side plate 420, and the opening direction of the receiving groove 440 is parallel to the left and right directions. The edge of the cutter body 410 facing away from the connecting side plate 420 is a blade, and there are multiple chicken embryo balancing holes 310, which are distributed in a rectangular array. In the initial state, the chicken embryo cutter 4 is located on one side of the chicken embryo tray 3 (such as Figure 2 As shown in FIG. 4 , when cutting, the cut chicken embryo residue is temporarily stored on the upper surface of the cutter body 410. As cutting proceeds, the subsequent chicken embryo residue pushes the previously cut chicken embryo residue until it enters the accommodating groove 440. The accommodating groove 440 provides more temporary storage space for the chicken embryo residue, preventing the chicken embryo residue from falling and causing contamination. The blade surface of the cutter body 410 is perpendicular to the vertical direction, and the lower side wall of the accommodating groove 440 is the upper blade surface of the cutter body 410.

[0048] Optionally, an accommodating transition plate 430 is provided between the connecting side plate 420 and the cutter body 410 . The accommodating transition plate 430 is an L-shaped bent plate, which cooperates with the cutter body 410 to form an accommodating groove 440 .

[0050] Taking the connection between the disinfection nozzle 6 and the disinfectant tank 26 as an example, the upper wall panel 110 is provided with a first sealing hole, which is equipped with a first sealing ring. The disinfection connecting outer tube 7 passes through the first sealing ring, and the elasticity of the first sealing ring ensures a seal between the disinfection connecting outer tube 7 and the upper wall panel 110. If the pipe needs to be cleaned or replaced, the disinfection connecting outer tube 7 can be simply pulled out of the first sealing ring. In addition, the disinfection liquid dispensing tube 11 is also connected to the upper wall panel 110, making it easy to disassemble and assemble the entire system.

[0051] In a specific implementation, a plurality of binding straps are provided on the upper wall plate 110, and the disinfection liquid dispensing tube 11 is fixed to the upper wall plate 110 by the binding straps. Alternatively, a first magnetic body is provided on the upper wall plate 110, and a second magnetic body is provided on the disinfection liquid dispensing tube 11, and the disinfection liquid dispensing tube 11 is fixed by the magnetic attraction between the first magnetic body and the second magnetic body.

[0052] In some embodiments, the allantoic fluid collection tube 5 is connected to the allantoic fluid collection container via the extraction outer tube 18, with the allantoic fluid collection tube 5 corresponding one-to-one to the extraction outer tube 18. Alternatively, the allantoic fluid collection container can be connected to a vacuum pump to create a negative pressure environment within the allantoic fluid collection container to extract the allantoic fluid. To achieve compatibility with the upper wall plate 110, a second sealing hole is provided on the upper wall plate 110, within which a second sealing ring is provided. The extraction outer tube 18 passes through the second sealing ring, and the elasticity of the second sealing ring achieves a seal between the extraction outer tube 18 and the upper wall plate 110. If the pipeline needs to be cleaned or replaced, simply remove the second sealing ring from the extraction outer tube 18.

[0053] In some embodiments, see Figure 6 The chicken embryo allantoic fluid harvesting device further includes an extraction mounting frame 19, on which each of the allantoic fluid collecting tubes 5 is mounted. A lifting mechanism is provided between the extraction mounting frame 19 and the upper wall plate 110, for raising and lowering the extraction mounting frame 19. In an initial state, the allantoic fluid collecting tubes 5 are at a higher position, away from the chicken embryo cutter 4. When the allantoic fluid needs to be extracted after cutting, the extraction mounting frame 19 is controlled to descend so that the allantoic fluid collecting tubes 5 are moved downward toward the chicken embryo below. After extraction is complete, the extraction mounting frame 19 is controlled to ascend so that the allantoic fluid collecting tubes 5 are moved upward away from the chicken embryo.

[0054] Optionally, the extraction mounting frame 19 includes multiple transverse frames 1910 and two longitudinal frames 1920. The transverse frames 1910 are parallel to each other and spaced apart along a first horizontal direction. The transverse frames 1910 extend in a second horizontal direction perpendicular to the first horizontal direction. The two longitudinal frames 1920 are connected to corresponding ends of each transverse frame 1910, and the longitudinal frames 1920 extend in the first horizontal direction. The allantoic fluid collection tubes 5 are connected to the bottom of the transverse frames 1910, and each transverse frame 1910 is provided with multiple allantoic fluid collection tubes 5 along its longitudinal axis. A space 1930 is formed between two adjacent horizontal frames 1910, and the disinfection dispensing pipe 11 is arranged corresponding to the space 1930. When the extraction installation frame 19 is in a high position, the disinfection nozzle 6, the disinfection connecting inner tube 8 and the disinfection lifting control mechanism 9 on the same disinfection dispensing pipe 11 are all arranged corresponding to the space 1930. The disinfection dispensing pipe 11, the disinfection nozzle 6, the disinfection connecting inner tube 8 and the disinfection lifting control mechanism 9 do not interfere with the extraction installation frame 19. During the descent of the extraction installation frame 19, the above-mentioned components will not interfere with the extraction installation frame 19, thereby ensuring the reliability of operation. Figure 6 The figure shows an exemplary top view of the distribution of the extraction installation frame 19 and the disinfection dispensing tube 11, wherein the dotted circle on the horizontal frame 1910 represents the first installation position 27 for installing the allantoic fluid collection tube 5, and the dotted circle on the disinfection dispensing tube 11 represents the second installation position 28 for installing the disinfection connecting inner tube 8.

[0055] In some embodiments, the extraction and lifting mechanism includes an extraction lifter and an extraction and lifting guide rod. The extraction and lifting guide rod is connected to the upper wall plate 110 and extends in the vertical direction. The extraction and lifting guide rod slides through the longitudinal frame 1920 of the extraction installation frame 19. The extraction lifter is connected to the upper wall plate 110, and its lifting end is connected to the central transverse frame 1910. The extraction lifter provides lifting power, and the extraction and lifting guide rod provides lifting guidance, ensuring the stability of the extraction installation frame 19's lifting operation. The extraction lifter can be implemented in ways that include, but are not limited to, a lifting cylinder, a lifting hydraulic cylinder, an electric push rod, etc.

[0056] In some embodiments, see Figure 4 Two conveyor rails 16 are provided in the left-right direction. The cross-section of the conveyor rails 16 is L-shaped to form a supporting and limiting space 1610. The supporting and limiting spaces 1610 of the two conveyor rails 16 are arranged opposite each other. An active guide seat 20 is slidably provided within the supporting and limiting space 1610 of one conveyor rail 16. A driving screw 21 is screwed into the active guide seat 20 and connected to the conveyor driver. A driven guide seat 22 is slidably provided within the supporting and limiting space 1610 of the other conveyor rail 16. A conveying guide rod 23 is slidably passed through the driven guide seat 22 and fixed to the corresponding conveyor rail 16. Supporting claws 24 are respectively provided on the active guide seat 20 and the driven guide seat 22 to support and fix the chicken embryo tray 3. The transmission driver rotates the driving screw 21. Since the transmission track 16 has an anti-rotation limit function on the active guide seat 20, the driving screw 21 drives the active guide seat 20 to move forward and backward. During this process, the driven guide seat 22 moves forward and backward synchronously. The transmission driver can be implemented by, but is not limited to, a stepper motor.

[0057] Optionally, in order to improve the stability of operation, a synchronization rod 25 is connected between the active guide seat 20 and the driven guide seat 22 so that the active guide seat 20 and the driven guide seat 22 form a whole, thereby improving the reliability of the synchronous operation of the two.

[0058] Optionally, in order to improve the reliability of the support of the chicken embryo tray 3, the supporting clamp 24 is fixed to the bottom of the chicken embryo tray 3 by vacuum adsorption or magnetic adsorption to prevent the chicken embryo tray 3 from moving or tipping over during transportation.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
