Description

Technical Field

[0001] This invention relates to the field of chicken embryo inoculation technology, specifically to an integrated, stable, and efficient chicken embryo inoculation machine. Background Technology

[0002] Chicken embryo inoculation is a core technology for culturing viruses from fertilized egg embryos. It mainly uses sites such as the chorioallantoic membrane, allantoic cavity, amnion cavity, or yolk sac as inoculation routes for virus isolation, amplification, or vaccine preparation.

[0003] First, select healthy chicken embryos, candle the eggs to confirm the air cell and injection site, disinfect the air cell end with iodine, drill a hole with a punch, then inject the virus, insert the needle into the egg to inject the virus suspension, then seal and incubate, and finally seal the hole with paraffin and incubate for a period of time.

[0004] Traditional techniques require replacing the needle after injecting the virus solution. This is because the needle, after being removed from the previous chicken embryo, is covered with egg liquid and impurities, which can contaminate the next chicken embryo during subsequent injections, leading to the failure of subsequent virus culture. For a large number of chicken embryos, repeatedly changing the needle is cumbersome and complicated, affecting the experimental or culture progress. Alternatively, the needle can be rinsed with cleaning solution without changing it. However, only the cleaning solution that comes into contact with the needle has a cleaning effect, and the cleaning solution that does not come into contact with the needle is wasted.

[0005] How to clean slender needles precisely and efficiently while avoiding waste of cleaning solution is a research direction in biotechnology. From the perspective of biomimetic science, insects use their forelegs to clean their slender needle-like mouthparts. One leg rests on the base of the mouthpart and then gradually strokes towards the tip, retracting the foreleg at the end. The other leg then repeats the action, with the two legs alternating to quickly and precisely clean the needle-like mouthparts. If this biological cleaning method can be biomimeticly applied to chicken embryo inoculation, the injection needle can be cleaned quickly, avoiding waste of cleaning solution and meeting the needs of rapid inoculation of large numbers of chicken embryos. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated, stable, and efficient chicken embryo inoculation machine to solve the problem of cleaning the inoculation needle mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an integrated, stable, and efficient chicken embryo inoculation machine, comprising a row of inoculators, an integrated frame connected to the top of the row of inoculators, a lifting mechanism for driving the integrated frame to rise and fall, and a gantry frame supporting the lifting mechanism. An egg-filling trough is placed below the inoculators, and multiple chicken embryos are arranged in a matrix within the egg-filling trough. The inoculator includes:

[0008] The device includes a needle device and two cleaning foot mechanisms evenly arranged around the needle device. The top of the needle device is connected to a tubing for supplying virus liquid. The bottom of the needle device injects virus liquid into the chicken embryo egg with the shell opening completed. After the injection, the two cleaning foot mechanisms clean the egg by alternately stroking the needle-like mouthparts with the front legs of a biomimetic insect.

[0009] The device includes a wheel drive cylinder surrounding the top of the needle device, an upper frame for supporting the wheel drive cylinder, and two fixed limiting frames surrounding the upper frame. Each limiting frame supports a foot cleaning mechanism. The two limiting frames also support the needle device. The top of the limiting frames is fixed to the integrated frame. A sliding groove is provided on the outer wall of the wheel drive cylinder to engage with a circular hole in the middle of the upper frame. A convex arc plate is provided at the bottom of the wheel drive cylinder to drive the foot cleaning mechanism.

[0010] The needle device includes a waist position assembly connected between two limiting uprights, a deflection cylinder penetrating the waist position assembly, a rigid tube fixed through the middle of the deflection cylinder, and a fine needle fixedly connected to the bottom end of the rigid tube.

The other end of the bottom of the F-shaped foot frame presses against a section of the cleaning belt to come into contact with the fine needle, and then moves towards the tip of the fine needle to wipe. After wiping, the clamping component releases the cleaning belt a certain distance, and at the same time the winding component collects the cleaning belt to make the cleaning belt taut.

[0015] The waist position assembly includes a bridge plate frame fixed between two limiting uprights, multiple pile blocks circumferentially fixed above the bridge plate frame, and a stopping spring fixed on each pile block. The stopping spring is engaged in an arc groove opened on the outer wall of the deflection cylinder, and the deflection cylinder is movably sleeved in a through hole opened on the bridge plate frame.

A gear is fixed at the other end of the side shaft to mesh with the increasing gear. A gear is fixed at the other end of the central shaft to mesh with a rack on the multi-fold frame. When the multi-fold frame descends to the end with the traveling plate frame, it is intercepted and pushed by the end stop frame.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. Traditional chicken embryo inoculation technology involves cumbersome and time-consuming needle replacement, and the cleaning process wastes cleaning solution, making it unsuitable for environments with a large number of chicken embryos being inoculated at once. This invention uses an inoculator for rapid inoculation, and after each inoculation, two cleaning foot mechanisms quickly and alternately wipe the fine needle tip, mimicking the way insect forelegs alternately stroke their needle-like mouthparts, so that the fine needle tip is cleaned efficiently and accurately, which is suitable for the needs of large-scale chicken embryo inoculation.

[0024] 2. The cleaning tape section in the foot device contacts the wiping needle. After wiping, the contaminated cleaning tape section is automatically transferred and replaced. The new cleaning tape section is used for the next round of wiping and cleaning. The contaminated cleaning tape is stored by the winding component. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the technical solutions of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1 to 14This invention provides a technical solution: an integrated, stable, and efficient chicken embryo inoculation machine, comprising a row of inoculators 1, an integrated frame 2 connected to the top of the row of inoculators 1, a lift 3 driving the integrated frame 2 to rise and fall, and a gantry frame 4 supporting the lift 3. An egg-holding trough 5 is placed below the inoculators 1, and multiple chicken embryos 6 are arranged in a matrix within the egg-holding trough 5. The main process of chicken embryo inoculation is as follows: the lift 3 controls the integrated frame 2 to descend, the integrated frame 2 drives the inoculators 1, and after the inoculators 1 descend, they inject virus solution into the chicken embryos 6 directly below. After inoculation, the lift 3 controls the integrated frame 2 to rise, the integrated frame 2 drives the inoculators 1, and the inoculators 1 complete self-cleaning during the rising process. Subsequently, the gantry frame 4 drives the lift 3 to move horizontally, thereby correspondingly controlling the horizontal movement of the row of inoculators 1. The inoculators 1 move horizontally above adjacent chicken embryos 6, and then descend to perform a new round of chicken embryo inoculation. The inoculator 1 includes:

[0042] The needle device 7 and two cleaning foot mechanisms 9 are evenly arranged around the needle device 7. The top of the needle device 7 is connected to a tube 71 for supplying virus liquid. The top of the tube 71 is connected to a virus liquid supply mechanism. The bottom of the needle device 7 is inserted into a predetermined position in the chicken embryo egg 6. The supply mechanism delivers virus liquid to the tube 71 and then injects it into the chicken embryo egg 6 below through the needle device 7. The bottom of the needle device 7 injects virus liquid into the chicken embryo egg 6 after the shell opening is completed. After the injection, the two cleaning foot mechanisms 9 clean the egg by alternately stroking the needle-like mouthparts of the front two legs of a biomimetic insect.

[0043] The top of the needle device 7 is surrounded by a wheel drive cylinder 8, an upper frame 10 for supporting the wheel drive cylinder 8, and two limiting brackets 11 fixed around the upper frame 10. Each limiting bracket 11 supports a foot cleaning mechanism 9. The two limiting brackets 11 also support the needle device 7. The top of the limiting brackets 11 is fixed on the integrated frame 2. The outer wall of the wheel drive cylinder 8 is provided with an annular sliding groove to engage with the round hole in the middle of the upper frame 10. The bottom of the wheel drive cylinder 8 is provided with a convex arc plate to drive the foot cleaning mechanism 9.

[0044] Reference Appendix Figure 4 Understandably, the needle device 7 includes a waist assembly 12 connected between two limiting uprights 11, a deflection cylinder 13 passing through the waist assembly 12, a rigid tube 14 fixedly passing through the middle of the deflection cylinder 13, and a fine needle 15 fixedly connected to the bottom end of the rigid tube 14. The top end of the rigid tube 14 is fixedly connected to the flexible tube 71.

[0045] Reference Appendix Figure 5 Understood, the foot cleaning mechanism 9 includes an L-shaped frame 16 that slides and rises in a square hole at the bottom of the limiting frame 11, a range extender 17 that drives the L-shaped frame 16, a foot device 18 supported by the L-shaped frame 16, a circulation device 19 for guiding the foot device 18 to move laterally, and a horizontal needle column 20 fixed on the L-shaped frame 16.

[0046] Two rail-mounted arc plates 131 are evenly arranged around the outside of the deflection cylinder 13. One end of the horizontal needle column 20 slides down into the wave groove opened on the rail-mounted arc plate 131 to make the deflection cylinder 13 deflect back and forth.

[0047] Reference Appendix Figure 6 The foot device 18 includes an F-shaped foot frame 21, a cleaning belt 22 conveyed along the outer surface of the F-shaped foot frame 21, a winding component 23 provided at one bottom end of the F-shaped foot frame 21, a clamping component 24 installed at the top end of the F-shaped foot frame 21, an end stop 25 for intercepting the clamping component 24, an L-shaped main rod 26 fixed on the F-shaped foot frame 21, and a spring 27 sleeved on the L-shaped main rod 26. The bottom horizontal column section on the F-shaped foot frame 21 slides through the square hole opened at the bottom end of the L-shaped frame 16, and the L-shaped main rod 26 slides through the through hole opened on the L-shaped frame 16. One end of the end stop 25 is fixed on the limiting stand 11.

[0048] The bottom of the F-shaped foot frame 21 is equipped with multiple rollers 211 to guide the cleaning belt 22 to change direction. The other end of the bottom of the F-shaped foot frame 21 presses against a section of the cleaning belt 22 to adhere to the fine needle 15, and then moves towards the tip of the fine needle 15 to wipe. After wiping, the clamping member 24 releases the cleaning belt 22 a certain distance, while the winding member 23 collects the cleaning belt 22 to keep the cleaning belt 22 taut.

[0049] Spring 27 is supported between the corner section of L-shaped main rod 26 and L-shaped frame 16. When the cleaning belt 22 is delivered to the outer surface of F-shaped foot frame 21, it has been pre-wetted. The cleaning belt 22 is treated with cleaning liquid. The top of the cleaning belt 22 is connected to the protective feeding mechanism. The clamping part 24 clamps a part of the cleaning belt 22, and a spare section is left between the clamping position and the protective feeding mechanism to ensure that the spare section of the cleaning belt 22 will not be stretched and broken when the cleaning belt 22 moves with the F-shaped foot frame 21.

[0050] Reference Appendix Figure 7 The waist-position assembly 12 includes a bridge plate frame 28 fixed between two limiting uprights 11, multiple pile blocks 30 fixed around the bridge plate frame 28, and a stop spring 29 fixed on each pile block 30. The stop spring 29 is engaged in an arc groove opened on the outer wall of the deflection cylinder 13. The deflection cylinder 13 is movably sleeved in a through hole opened on the bridge plate frame 28. The deflection cylinder 13 swings back and forth under the drive of the sliding horizontal needle column 20. After the horizontal needle column 20 falls to the bottom, it rises and resets. The deflection cylinder 13 swings back and forth in the opposite direction. Finally, the horizontal needle column 20 rises to the top. The deflection cylinder 13 will not rotate on its own because the stop spring 29 is engaged. In this way, the horizontal needle column 20 will accurately slide into the wave groove on the rail arc plate 131 in a new round of sliding.

[0051] Reference Appendix Figure 8The range extender assembly 17 includes a lever shaft 32 and an amplifying shaft 35, which are respectively movably sleeved in two through holes on the limiting frame 11; an amplifying frame 34 fixed at one end of the lever shaft 32; a first column 31 fixed on the lever shaft 32; an amplifying gear 36 fixedly sleeved on the amplifying shaft 35; and a V-shaped spring 33 fixed on the limiting frame 11. The first column 31 is encountered by the convex arc plate on the drive cylinder 8. An arc-shaped rack is provided at one end of the amplifying frame 34 to mesh with the gear fixed at the end of the amplifying shaft 35. The amplifying gear 36 meshes with the rack provided on the L-shaped frame 16. The V-shaped spring 33 pushes the amplifying frame 34 to reset.

[0052] An external gear ring is fixed at the upper end of the wheel drive cylinder 8 to connect to the existing motor drive mechanism. The wheel drive cylinder 8 is driven to rotate. During the process, the convex arc plate on the wheel drive cylinder 8 pushes the first column 31 it encounters. The first column 31 swings to drive the amplification frame 34, which in turn causes the amplification shaft 35 to rotate. Then, through the amplification gear 36, it drives the L-shaped frame 16. The L-shaped frame 16 slides down. After the convex arc plate of the wheel drive cylinder 8 separates from the first column 31, the L-shaped frame 16 returns to its original position and rises.

[0053] The circulation device 19 includes a double support plate frame 40 with one end fixed to the limiting stand 11, a V-shaped plate 41 and a Z-shaped plate 42 fixed at the other end of the double support plate frame 40, an L-shaped swing shaft 38 movably sleeved in a through hole on the double support plate frame 40, a door panel 39 fixed at one end of the L-shaped swing shaft 38, and a C-shaped spring piece 37 contacted at the other end of the L-shaped swing shaft 38, with one end of the C-shaped spring piece 37 fixed to the double support plate frame 40;

[0054] The L-shaped main rod 26, which goes down first and then up, completes a closed-loop sliding under the guidance of the door panel 39, the Z-shaped plate 42 and the V-shaped plate 41. Then the L-shaped main rod 26 drives the F-shaped foot frame 21, causing the F-shaped foot frame 21 to descend against the fine needle 15. Afterwards, the F-shaped foot frame 21 rises after moving away from the fine needle 15.

[0055] Reference Appendix Figure 9 Under the pressure of spring 27, the L-shaped main rod 26 tends to move to the right. The L-shaped main rod 26 slides down the left side of door panel 39, then slides to the left side of Z-shaped plate 42. The L-shaped main rod 26 moves laterally to the left, controlling the auxiliary... Figure 6The F-shaped footrest 21 moves a section of the cleaning belt 22 to the left, and the cleaning belt 22 adheres to the fine needle 15. The L-shaped main rod 26 continues to slide down, and the corresponding section of the cleaning belt 22 wipes the fine needle 15. After the L-shaped main rod 26 reaches its end, it falls to the right onto the left side of the V-shaped plate 41, and the corresponding section of the cleaning belt 22 and the fine needle 15 separate. The L-shaped main rod 26 rises along the left side of the V-shaped plate 41, and the corresponding F-shaped footrest 21 drives the cleaning belt 22 to reset and rise. The L-shaped main rod 26 passes smoothly through the door panel 39 by lifting it up. Then the door panel 39 is placed back on the V-shaped plate 41, and the L-shaped main rod 26 rises and resets. The L-shaped main rod 26 will start a new round of descent from the left side of the door panel 39 again.

[0056] The winding component 23 is a prior art device that tends to wind up the cleaning tape 22, keeping the cleaning tape 22 taut. The winding component 23 includes an L-shaped support rod 234 with one end fixed to the F-shaped support frame 21, a first spring 232 fixedly sleeved on the L-shaped support rod 234, a drum 235 fixedly sleeved on the outside of the first spring 232, ear plates 233 fixed on both sides of the drum 235, and blade plates 231 blocking both sides of the wound cleaning tape 22. The blade plates 231 are fixed on the drum 235. A portion of the L-shaped support rod 234 is movably sleeved in the through hole opened on the ear plate 233. One end of the cleaning tape 22 is wound around the drum 235, and the first spring 232 provides rotational pressure to the drum 235.

[0057] The clamping component 24 includes a traveling plate frame 44 with one end fixed to the F-type foot frame 21, a row of stationary wheels 45 supported on the traveling plate frame 44, an integrated worm gear 46 for driving the row of stationary wheels 45, a pressure head assembly 43 for transmitting the integrated worm gear 46, and a pressing assembly 47 that cooperates with the stationary wheels 45 to clamp the cleaning belt 22. One end of the stationary wheel 45 is provided with a shaft that is movably sleeved in a through hole opened on the traveling plate frame 44, and a worm wheel is fixed on the shaft to mesh with the integrated worm gear 46 for transmission. The rod on the integrated worm gear 46 is movably sleeved in the through hole opened on the traveling plate frame 44.

[0058] The pressing assembly 47 includes an extension plate 51 fixed on the F-shaped foot frame 21, an L-shaped cover frame 49 that slides through a plate hole in the extension plate 51, a row of moving wheels 50 supported on the L-shaped cover frame 49, and a wave spring sheet 48 fixedly connected between the extension plate 51 and the L-shaped cover frame 49. A row of stationary wheels 45 and a row of moving wheels 50 cooperate to clamp a partial wave-shaped section of the cleaning belt 22.

[0059] The pressure head assembly 43 includes a side shaft 55 and a central shaft 54 ​​respectively movably sleeved in two shaft holes on the accompanying plate frame 44, a one-way bearing 52 fixedly sleeved at one end of the central shaft 54, an increasing gear 57 fixedly sleeved outside the one-way bearing 52, a second spring 53 fixedly sleeved on the central shaft 54, and a multi-fold frame 56 that slides through a square hole at one end of the accompanying plate frame 44. The outer end of the second spring 53 is fixed on the accompanying plate frame 44. A bevel gear is fixed at one end of the side shaft 55 to drive the bevel gear fixed at the end of the integrated worm gear 46. A gear is fixed at the other end of the side shaft 55 to mesh with the increasing gear 57. A gear is fixed at the other end of the central shaft 54 ​​to mesh with the rack on the multi-fold frame 56. The multi-fold frame 56 is intercepted and pushed by the end stop frame 25 when the accompanying plate frame 44 descends to the end.

[0060] Analysis of the main function of the clamping component 24: The F-type foot frame 21 drives a partial section of the cleaning belt 22 to adhere to the fine needle 15. The partial section of the cleaning belt 22 descends to wipe the fine needle 15. After the two separate, the partial section of the cleaning belt 22 is transferred and conveyed towards the winding component 23. The partial section of the cleaning belt 22 with attached impurities is recovered. Then the cleaning belt 22 moves laterally away from the fine needle 15. The principle of conveying the partial section of the cleaning belt 22 is that the clamping component 24 holding the cleaning belt 22 releases a certain distance, and the winding component 23 automatically and synchronously winds up the cleaning belt 22.

[0061] Originally, the wave spring 48 provides tension to the L-shaped cover frame 49, which drives a row of moving wheels 50. The moving wheels 50 and stationary wheels 45 work together to firmly clamp the cleaning belt 22. When the multi-fold frame 56 is blocked by the end block 25, it will cause the clamped cleaning belt 22 to be conveyed. Specifically, it is attached... Figure 14 The multi-fold frame 56 rises, which in turn drives the central shaft 54 ​​to rotate. Subsequently, the one-way bearing 52 drives the increasing gear 57 to rotate, which in turn drives the integrated worm gear 46 through the side shaft 55. The rotation of the integrated worm gear 46 drives a row of stationary wheels 45 to rotate. The rotation of the stationary wheels 45 causes the cleaning belt 22 to be conveyed. In this way, the cleaning belt 22 is conveyed a short distance towards the bottom of the F-shaped foot frame 21. At the same time, the winding component 23 winds up the excess cleaning belt 22. The wiping section of the cleaning belt 22 is always kept taut. Figure 6 A section of the cleaning belt 22 at the bottom left end of the F-type footrest 21 was replaced, and the new section of the cleaning belt 22 was used for the next round of wiping and cleaning.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The device includes a wheel drive cylinder surrounding the top of the needle device, an upper frame for supporting the wheel drive cylinder, and two fixed limiting frames surrounding the upper frame. Each limiting frame supports a foot cleaning mechanism. The two limiting frames also support the needle device. The top of the limiting frames is fixed on the integrated frame. A sliding groove is provided on the outer wall of the wheel drive cylinder to engage with a circular hole in the middle of the upper frame. A convex arc plate is provided at the bottom of the wheel drive cylinder to drive the foot cleaning mechanism. The needle device includes a waist component connected between two limiting uprights, a deflection cylinder passing through the waist component, a rigid tube fixed through the middle of the deflection cylinder, and a fine needle fixedly connected to the bottom end of the rigid tube. The top end of the rigid tube is fixedly connected to the flexible tube. The foot cleaning mechanism includes an L-shaped frame that slides and rises in a square hole at the bottom of the limiting frame, a range extender that drives the L-shaped frame, a foot device supported by the L-shaped frame, a circulation device for guiding the foot device to move laterally, and a horizontal needle column fixed on the L-shaped frame. Two rail-mounted arc plates are evenly arranged around the outside of the deflection cylinder. One end of the horizontal needle column slides down into the wave groove opened on the rail-mounted arc plate to make the deflection cylinder deflect back and forth. The foot device includes an F-shaped foot frame, a cleaning belt conveyed along the outer surface of the F-shaped foot frame, a winding component set at one bottom end of the F-shaped foot frame, a clamping component installed at the top of the F-shaped foot frame, an end stop for intercepting the clamping component, an L-shaped main bar fixed on the F-shaped foot frame, and a spring sleeved on the L-shaped main bar. The bottom horizontal column section of the F-shaped foot frame slides through a square hole opened at the bottom end of the L-shaped frame, and the L-shaped main bar slides through a through hole opened on the L-shaped frame. One end of the end stop is fixed on the limiting stand. The bottom of the F-type foot frame is equipped with multiple rollers to guide the cleaning belt conveyor to change direction. The other end of the bottom of the F-type foot frame presses against a section of the cleaning belt to come into contact with the fine needle, and then moves towards the tip of the fine needle to wipe. After wiping, the clamping component releases the cleaning belt a certain distance, and at the same time the winding component collects the cleaning belt to make the cleaning belt taut. The waist position assembly includes a bridge plate frame fixed between two limiting uprights, multiple pile blocks fixed around the bridge plate frame, and a stopping spring fixed on each pile block. The stopping spring is engaged in an arc groove opened on the outer wall of the deflection cylinder, and the deflection cylinder is movably sleeved in a through hole opened on the bridge plate frame. The range extender assembly includes a lever shaft and an amplifying shaft that are movably sleeved in two through holes on a limiting frame, an amplifying frame fixed at one end of the lever shaft, a first column fixed on the lever shaft, an amplifying gear fixedly sleeved on the amplifying shaft, and a V-shaped spring plate fixed on the limiting frame. The first column is encountered when the convex arc plate on the drive cylinder is rotated around it. An arc-shaped rack is provided at one end of the amplifying frame to mesh with the gear fixed at the end of the amplifying shaft. The amplifying gear meshes with the rack provided on the L-shaped frame. The V-shaped spring plate pushes the amplifying frame to reset. The circulation device includes a double support plate frame with one end fixed to the limiting stand, a V-shaped plate and a Z-shaped plate fixed at the other end of the double support plate frame, an L-shaped swing shaft movably sleeved in a through hole in the double support plate frame, a door panel fixed at one end of the L-shaped swing shaft, and a C-shaped spring piece contacted by the other end of the L-shaped swing shaft, with one end of the C-shaped spring piece fixed to the double support plate frame. The L-shaped main rod slides in a closed loop under the guidance of the door panel, Z-shaped plate and V-shaped plate. Then the L-shaped main rod drives the F-shaped foot frame, which descends against the fine needle. After that, the F-shaped foot frame rises away from the fine needle.
