Description

Technical Field

[0001] The invention relates to the technical field of breeding auxiliary tools, in particular to an optimal device for a chicken embryo virus injection head. Background Art

[0002] A large number of virus vaccines in production and life, such as vaccinia vaccine, influenza vaccine, avian influenza inactivated vaccine, bursal vaccine, subunit vaccine of virus, Newcastle vaccine, turkey rhinotracheitis vaccine, etc., are all cultivated in chicken embryos (fertilized eggs in incubation). Therefore, an injection head is needed to inject the virus into the fertilized eggs of 5-10 days of incubation. However, during the injection process, due to improper selection of parameters such as needle shape, needle thickness, needle speed, needle module weight, crack (micro-crack) eggs will be produced, resulting in virus culture failure. During virus culture, due to the different varieties, origins, feeding methods, etc. of the eggs, the mechanical properties of the eggshells are different, and the injection parameters must be adjusted (otherwise the eggshells will crack, resulting in virus culture failure). Furthermore, in addition to chicken embryos (eggs), when other poultry eggs (such as duck eggs, etc.) are injected with viruses, different injection parameters need to be changed. The prior art lacks the device and method for realizing the optimization of chicken embryo virus injection heads. Summary of the invention

[0008] Optionally, there are multiple slide rails, and the lifting frame is provided with multiple slide grooves, which are slidably connected to the multiple slide rails in a one-to-one manner. A one-way damping buffer is provided at the side bottom of each slide rail. After descending, the lifting frame touches the one-way damping buffer to slow down and buffer the lifting frame.

[0009] Optionally, it also includes a relatively arranged scale and a high-speed camera, which are respectively located on both sides of the vibration-absorbing egg tray. The high-speed camera takes pictures during the descent of the side hole needle to capture the position of the side hole needle on the scale to obtain the speed of the side hole needle.

[0025] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments. The present invention covers any substitution, modification, equivalent method and scheme made within the spirit and scope of the present invention.

[0026] In order to enable the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without these detailed descriptions.

[0027] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the accompanying drawings are all simplified and use non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0028] like Figure 1-3 As shown, a preferred device of the chicken embryo virus injection head of the present invention is illustrated, comprising a lifting frame 1-3, a vibration-absorbing egg tray 3 for accommodating chicken embryo eggs, a CCD camera 5-1 and a vertically arranged slide rail 6-1, wherein the lifting frame 1-3 is slidably connected to the slide rail 6-1, a side hole needle 1-6 is vertically arranged downward on the middle bottom surface of the lifting frame 1-3, and a counterweight 1-4 is arranged in the middle upper part of the lifting frame 1-3; the vibration-absorbing egg tray 3 is located directly below the middle part of the lifting frame 1-3; the CCD camera 5-1 is movably arranged on the side of the vibration-absorbing egg tray 3;

[0029] Under the action of gravity, the lifting frame 1-3 descends along the slide rail 6-1 to pierce the eggshell; the lifting frame 1-3 is moved out, and the CCD camera 5-1 is moved in so that it is located directly above the vibration-absorbing egg tray 3, and the eggshell of the chicken embryo egg is photographed to determine whether the chicken embryo egg has cracks. The greater the distance between the position of the lifting frame 1-3 on the slide rail 6-1 and the bottom plate 6-3, the faster the injection speed. The counterweight 1-4 is replaceable. During injection, the CCD camera 5-1 and the coated convex lens 5-3 are moved out, and the lifting frame 1-3 performs free fall motion to pierce the eggshell. Then the lifting frame 1-3 is removed, and the camera takes a picture of the eggshell to determine whether the chicken embryo has cracks.

[0030] The CCD camera 5-1 is installed on the CCD camera bracket 5-2, and a coated convex lens 5-3 is also provided on the CCD camera bracket 5-2. The coated convex lens 5-3 is located below the CCD camera 5-1. The CCD camera 5-1 shoots the eggshell of the chicken embryo egg through the coated convex lens 5-3.

[0031] like Fig.10As shown, the interior of the vibration-absorbing egg tray 3 is provided with an egg-illuminating light source 3-3, the vibration-absorbing egg tray 3 is concave to form a receiving cavity, the bottom opening of the receiving cavity serves as a light source through hole 3-5, the inner wall of the receiving cavity is provided with vibration-absorbing cotton 3-1, and the upper outer edge plane of the vibration-absorbing egg tray 3 is covered with a black shading cloth 8.

[0032] There are multiple slide rails 6-1, and the lifting frame 1-3 is provided with multiple slide grooves 1-3-1. The slide grooves 1-3-1 are slidably connected with the multiple slide rails 6-1 one by one. A one-way damping buffer 2 is provided at the side bottom of each slide rail 6-1. The lifting frame 1-3 touches the one-way damping buffer 2 after descending, thereby slowing down and buffering the lifting frame 1-3.

[0033] like Figure 4 , 5 As shown, the structure of the lifting frame 1-3 is schematically shown, including a middle part and a plurality of connecting rods, each of which is provided with a slide groove 1-3-1, the slide groove 1-3-1 is made of brass, and the slide rail 6-1 is made of stainless steel, and the two cooperate to form a sliding bearing with a very small friction coefficient. The slide groove 6-1 is provided with a slide rail hole 6-1-1, which can store grease inside for lubrication and can also be used for positioning.

[0034] like Figure 6 When the needle is injected, the CCD camera 5-1 and the coated convex lens 5-3 move to the left; after the injection, the lifting frame is removed, and the camera 5-1 and the coated convex lens 5-3 move to the right to shoot the chicken embryo.

[0035] like Figure 7 As shown, the present invention also includes a relatively arranged scale 4-3 and a high-speed camera 4-2, which are respectively located on both sides of the vibration-absorbing egg tray 3. The high-speed camera 4-2 shoots during the descent of the side hole needle 1-6, and is used to shoot the position of the side hole needle 1-6 on the scale to obtain the speed of the side hole needle 1-6.

[0036] like Figure 8 , 9aAs shown in Figure 9b, the one-way damping buffer 2 includes a buffer plate 2-1, a spring 2-2, a damper cylinder cover 2-3 and a damper cylinder body 2-4. The damper cylinder cover 2-3 covers the damper cylinder body 2-4. The spring 2-2 is sleeved between the buffer plate 2-1 and the damper cylinder cover 2-3. The damper cylinder body 2-4 is provided with an inner hole 2-4-1, and a conical bottom hole 2-4-2 is provided at the lower part. A damper support ring 2-6 is provided in the damper cylinder body 2-4. The buffer plate A piston column 2-7 is provided below 2-1, and the piston column 2-7 extends downward into the damper cylinder 2-4. The piston column 2-7 includes a piston 2-7-1 and a damper piston cone 2-7-2. A retaining ring is provided on the piston 2-7-1, and the retaining ring is engaged with the damper support ring 2-6. The damper cylinder 2-4 is installed on the damper base plate 2-8 via a bracket, and lubricating oil 2-9 is set in the space enclosed by the damper cylinder 2-4, the bracket and the damper base plate 2-8.

[0037] When the lifting frame 3-1 reaches the lowest point, it touches the buffer plate 2-1, causing the buffer plate 2-1 to descend. The lower part of the piston column 2-7 is conical, which matches the conical bottom hole 2-4-2. When the piston column 2-7 gradually descends and matches the conical bottom hole 2-4-2, the gap becomes smaller and smaller, and the flow of the lubricating oil becomes smaller and smaller, which prevents the piston column 2-7 from descending and plays a damping role. When the viscosity of the lubricating oil, the conical size of the lower part of the piston column 2-7, and the size of the conical bottom hole 2-4-2 are selected to appropriate values, the speed of 3-1 when it reaches the lowest position can be exactly zero.

[0038] After the image captured by the CCD camera 5 - 1 is gray-scaled and binarized, edge detection is performed on the image, and a contour is drawn according to the result of the edge detection, and whether there is a crack is determined based on the contour.

[0039] Based on the above-mentioned chicken embryo virus injection head optimization device, a chicken embryo virus injection head optimization method can be formed.

It is the opinion of ordinary technicians in this field that the embodiments can be replaced and integrated. If the content is not clearly recorded in one of the embodiments, reference can be made to another recorded embodiment.

The present invention is not limited to the above embodiments, and its specific structure is allowed to be changed. In short, all changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
