Description

Technical Field

[0001] This utility model relates to the technical field of automatic inoculation devices for livestock and poultry egg embryos, and in particular to an egg tray and an inoculation device. Background Technology

[0002] Intraembryonic immunization is the most effective measure for early prevention and control of duck diseases. However, current automated vaccination equipment is designed for chicken embryos, and there is a lack of automated vaccination equipment for duck embryos, which hinders the use of intraembryonic immunization in duck disease control. Chicken eggs are small, and the size difference between eggs is small. When using automated equipment for vaccination, conventional egg trays can fix the position and height of the eggs, ensuring that the vaccine is injected into a fixed position on the chicken embryo. However, duck eggs are larger, and the size difference between eggs is greater. Therefore, a special duck egg tray must be designed to fix the position and height of the eggs, so as to ensure that the injection depth of the automated vaccination equipment meets the injection requirements for duck embryos of different sizes.

[0003] Existing technology uses a connector on a mounting base that can slide relative to the mounting base. The connector has a groove for placing the egg embryo. By adjusting the position of the connector, the size of the groove can be adjusted to accommodate egg embryos of different sizes. However, this is only an improvement based on the applicable type of egg embryo. For example, the groove is made smaller to accommodate chicken egg embryos and larger to accommodate duck egg embryos. It does not take into account the differences in size between egg embryos of the same type.

[0004] Therefore, how to provide an egg tray and vaccination device that can be adapted to poultry eggs of different sizes and ensure that the automatic vaccination device injects the vaccine into a fixed position on the egg embryo is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to address the deficiencies and shortcomings of the existing technology by providing an egg tray and a vaccination device that can be adapted to egg embryos of different sizes, ensuring that the automatic vaccination device injects the vaccine into a fixed position on the egg embryo.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides an egg tray, including: an egg tray frame, wherein the egg tray frame is a frame structure;

[0008] The egg tray is provided inside the frame structure. A position fixer is provided inside the egg tray, and the position fixer includes at least two groove compensation units. All the groove compensation units can close together to form a groove for placing the egg embryo. The groove compensation units can adjust their shape and / or position according to the size of the placed egg embryo, and the initial size of the groove is not larger than the smallest egg embryo. A height fixer is provided at the bottom of each egg tray. The height fixer has a first cavity inside, which communicates with the groove and can be fixed at a certain position in the egg tray to fix the height position of the egg embryo.

[0009] In one embodiment, the groove compensation unit is an arc-shaped spring sheet. One end of the spring sheet is a fixed end, which is connected to the inner wall of the egg groove. The other end of the spring sheet is a free end. The distance between the free end and the inner wall of the egg groove is greater than the distance between the fixed end and the inner wall of the egg groove, so that all the spring sheets can close together to form the groove that is larger at the top and smaller at the bottom.

[0010] In one embodiment, all the spring sheets are covered with a soft cushioning layer.

[0011] In one embodiment, the groove compensation unit includes a clamping plate and an elastic component. The inner surface of the clamping plate is arc-shaped, and the distance between the upper end of the inner surface and the inner wall of the egg groove is less than the distance between the lower end of the inner surface and the inner wall of the egg groove, so that all the clamping plates can close together to form the groove that is larger at the top and smaller at the bottom. At least one set of elastic components is provided between the outer surface of the clamping plate and the inner wall of the egg groove, and the extension and retraction directions of all the elastic components are perpendicular to the inner wall of the egg groove, so that the clamping plate can only move in a direction parallel to the inner wall of the egg groove.

[0012] In one embodiment, a soft buffer layer is provided on the inner surface of all the clamping plates.

[0013] In one embodiment, the height fixer is a support frame, which includes at least three non-deformable support arms. One end of each support arm is connected to the inner wall of the egg tray, and the other ends of all the support arms intersect at one point to form the first cavity.

[0014] In one embodiment, all of the arms are covered with a soft cushioning layer.

[0015] In one embodiment, the height fixer is a non-deformable hood with an opening on the side of the hood near the egg slot to form the first cavity between the inner wall of the hood and the spring sheet or the clamping plate.

[0016] In one embodiment, the inner wall of the hood is lined with a soft cushioning pad.

[0017] This utility model also provides a vaccination device, comprising: an egg tray; and an injection device, wherein the injection device includes at least two injection needles, and the injection needles correspond one-to-one with the egg tray to inject a vaccine into an egg embryo placed in the egg tray.

[0018] The present invention achieves the following technical advantages over the prior art:

[0019] The position fixing device inside the egg tray includes at least two groove compensation units. These units can close together to form a groove for placing the embryo. The groove compensation units can adjust their shape and / or position according to the size of the embryo being placed, and the initial size of the groove is no larger than the smallest embryo, ensuring that embryos of different sizes can be stably placed in the egg tray without the embryos moving or failing to fit. A height fixing device at the bottom of the egg tray fixes the placement height of the embryo, ensuring the needle insertion depth meets injection requirements. In other words, by fixing the placement position of the embryo in the egg tray, the automated vaccination equipment can inject the vaccine into a fixed location on the embryo (where the fixed location should be understood as the range that meets the injection depth requirements), improving the injection success rate.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 8As shown, this utility model provides an egg tray, including an egg tray frame 3 and egg slots 4. The egg tray frame 3 is a frame structure, and the shape of the frame structure can be square, round, elliptical, rhomboid, etc. In one embodiment, the frame structure is a square composed of a bracket crossbeam 1 and a bracket vertical beam 2. The frame structure has egg slots 4 inside, and the number and arrangement of egg slots 4 can be set according to actual needs. The egg slots 4 have position fixers 5 inside, and the position fixers 5 include at least two groove compensation units. All groove compensation units can be closed to form a groove 8 that is larger at the top and smaller at the bottom. The groove 8 is used to place egg embryos, and the groove compensation units can adjust the position of the placed egg embryos according to the size of the placed egg embryos. The size adjustment mechanism adjusts its shape and / or position, and the initial size of the groove 8 is not larger than the smallest egg embryo, so as to accommodate egg embryos of different sizes, so that egg embryos of different sizes can be stably placed in the egg tray 4, avoiding shaking or the egg embryo being unable to be placed in the egg tray 4; each egg tray 4 is provided with a height fixer 6 at the bottom, and the height fixer 6 has a first cavity inside, which is connected to the groove 8. Most of the egg embryo is placed in the groove 8, and the end of the egg embryo extends out of the groove 8 and abuts against the inner wall of the first cavity. The first cavity can be fixed at a certain position in the egg tray 4 to fix the placement height of the egg embryo in the egg tray 4.

[0033] The first cavity being fixed at a specific position in the egg tray 4 includes two scenarios. The first scenario: by setting the first cavity at an appropriate height, it ensures that the depth to which the needle is injected into different egg embryos meets the injection range requirements. In this case, fixing the first cavity at a specific position in the egg tray 4 ensures that its shape and position (especially its position in the height direction) do not change with the size of the egg embryo. This scenario is mainly applicable when the size difference between egg embryos does not exceed the depth range required for vaccine injection. For example, when placing egg embryos of the same type (all chicken egg embryos or all duck egg embryos) in the egg tray 4, and the size difference between different egg embryos of this type is small and will not exceed the depth range required for vaccine injection, thus ensuring that the depth to which the needle is injected into different egg embryos meets the injection range requirements.

[0034] The second scenario: If setting the first cavity at a suitable height cannot meet the injection depth requirements for all egg embryos, a sliding component is installed between the height fixer 6 and the inner wall 7 of the egg tray. This allows the height fixer 6 to slide relative to the egg tray 4 in the height direction. Once adjusted to a suitable position, its position is fixed. The sliding component can be a manual structure, such as a slider on the height fixer 6, a groove on the inner wall 7 of the egg tray, and a threaded hole on the side wall of the egg tray 4. After the height fixer 6 slides along the inner wall 7 to a suitable position, a threaded connector is inserted to lock its position. This method is only suitable for egg trays 4 located at the edge of the egg holder 3. Alternatively, it can be an electric structure, such as a rack on the height fixer 6 and a gear and drive assembly on the inner wall 7 of the egg tray; or a nut on the height fixer 6 and a lead screw and drive assembly on the inner wall 7 of the egg tray. The drive assembly must be positioned so as not to affect the placement of the egg embryos in the egg tray 4 or the movement of the height fixer 6. When the position of the height fixator 6 needs to be adjusted, the drive component connected to this structure is activated. After adjustment to the appropriate position, the drive component is deactivated to lock the height fixator 6 in that position. The appropriate position refers to the first cavity position that meets the requirements of the egg embryo injection depth range. The sliding component's structure is not limited to the forms listed above. This situation mainly applies when the size difference between egg embryos exceeds the depth range requirement for vaccine injection, such as when both chicken and duck egg embryos need to be vaccinated simultaneously, and the size difference between them is significant, exceeding the depth range requirement for vaccine injection; or when the size difference between egg embryos of the same type exceeds the depth requirement for vaccine injection.

[0035] The groove compensation unit can have different configurations. In one embodiment, such as... Figure 2As shown, the groove compensation unit is an arc-shaped spring plate 51. One end of the spring plate 51 is a fixed end 511, which is connected to the inner wall 7 of the egg tray. The other end of the spring plate 51 is a free end 512. The distance between the free end 512 and the inner wall 7 of the egg tray is greater than the distance between the fixed end 511 and the inner wall 7 of the egg tray, so that all the spring plates 51 can close together to form a groove 8 that is larger at the top and smaller at the bottom. For the egg tray 4 located in the edge area of ​​the egg holder 3, the inner wall 7 of the egg tray may overlap with the inner wall of the egg holder 3. In this case, it is collectively referred to as the inner wall 7 of the egg tray. When no egg embryo is placed in the groove, the size of the groove 8 should not be larger than the smallest egg embryo. When an egg embryo is placed in the groove, the spring plate 51 is subjected to the squeezing force exerted by the egg embryo and deforms towards the side wall of the egg tray 4 to expand the groove 8, so that the egg embryo can be stably placed in the groove 8. Easily deformable spring sheets 51, or spring sheets 51 with a small stiffness coefficient k, should be selected to reduce the compressive force exerted by the spring sheets 51 on the egg embryo under a given deformation, thus reducing the risk of egg embryo breakage. When placing the egg embryo, the larger end should face upwards and the smaller end downwards. Because the size difference between the smaller ends of different egg embryos is relatively small, this placement method can reduce the deformation of the spring sheets 51, thereby reducing the risk of egg embryo breakage. In addition, all spring sheets 51 are covered with a soft cushioning layer to prevent the egg embryo from being bumped or damaged. The soft cushioning layer can be any of the following: silicone layer, sponge layer, latex layer, memory foam layer, felt layer, etc.

[0036] In another embodiment, the groove compensation unit includes a clamping plate 52 and an elastic component 53. The inner surface of the clamping plate 52 is an arc surface. The distance between the upper end 521 of the inner surface and the inner wall 7 of the egg tray is less than the distance between the lower end 522 of the inner surface and the inner wall 7 of the egg tray, so that all the clamping plates 52 can close together to form a groove 8 that is larger at the top and smaller at the bottom. Similarly, when the inner wall 7 of the egg tray coincides with the inner wall of the egg tray 3, it is uniformly referred to as the inner wall 7 of the egg tray. At least one set of elastic components 53 is provided between the outer surface of the clamping plate 52 and the inner wall 7 of the egg tray. The deformation direction of all elastic components 53 is perpendicular to the inner wall 7 of the egg tray connected to them, so that the clamping plate 52 can move in a manner in which its tangential plane is parallel to the inner wall 7 of the egg tray connected to the elastic component 53, without the clamping plate 52 colliding with the inner wall of the first cavity. The above description corresponds to the case where the inner wall 7 of the egg groove is a vertical plane. For the case where the inner wall 7 is an arc surface, the deformation direction of the elastic component 53 should be perpendicular to the tangential plane of the inner wall 7 connected to it. This allows the clamping plate 52 to move with its tangential plane parallel to the tangential plane of the inner wall 7 connected to the elastic component 53. The inner surface refers to the surface where the two clamping plates 52 face each other, and the outer surface refers to the surface where the two clamping plates 52 face away from each other, or the surface of the clamping plate 52 closest to the inner wall 7 of the egg groove. Similarly, when no egg embryo is placed in the groove, the size of the groove 8 should not be larger than the smallest egg embryo. When an egg embryo is placed in the groove, the elastic component 53 compresses and deforms, causing the clamping plate 52 to move closer to the side wall of the egg groove 4, thus expanding the size of the groove 8 and allowing the egg embryo to be stably placed within it. An easily deformable elastic component 53 should be selected, or an elastic component 53 with a small stiffness coefficient k should be selected to reduce the compressive force applied to the egg embryo by the elastic component 53 under a given deformation, thereby reducing the risk of egg embryo breakage. In one embodiment, the elastic component 53 is a spring. Furthermore, when placing the egg embryo, the larger end of the embryo faces upwards and the smaller end downwards. Because the size difference between the smaller ends of different egg embryos is relatively small, this placement method can reduce the deformation of the spring sheet 51, thereby reducing the risk of egg embryo breakage. In addition, the inner surface of all clamping plates 52 is provided with a soft cushioning layer to prevent the egg embryo from being bumped or damaged. The soft cushioning layer can be any of the following: silicone layer, sponge layer, latex layer, memory foam layer, felt layer, etc.

[0037] The height fixing device 6 can also have various different configurations. In one embodiment, such as... Figure 3As shown, the height fixer 6 is a support frame, which includes at least three non-deformable support arms 61. One end of each support arm 61 is connected to the inner wall 7 of the egg tray. The other ends of all the support arms 61 forming the same height fixer 6 intersect at one point to form a first cavity. The number of support arms 61 can be three, four, five or more, and adjacent support arms 61 are spaced apart and evenly distributed. Similarly, when the inner wall 7 of the egg tray coincides with the inner wall of the egg holder 3, it is uniformly referred to as the inner wall 7 of the egg tray. For this type of height fixer 6, if a sliding component is required, the sliding component can be set between the support arm 61 and the inner wall 7 of the egg tray. To prevent the egg embryo from touching the inner wall of the first cavity and causing the egg embryo to break, a soft buffer layer is wrapped around the outside of all support arms 61. The material of the soft buffer layer is the same as that of the soft buffer layer in the groove compensation unit, and will not be described again here.

[0038] In another embodiment, the height fixer 6 is a non-deformable hood 62. The hood 62 can be a bowl-shaped structure, an arc-shaped plate structure, etc. The side wall of the hood 62 is connected to the inner wall 7 of the egg tray. Similarly, when the inner wall 7 of the egg tray coincides with the inner wall of the egg holder 3, it is uniformly referred to as the inner wall 7 of the egg tray. The hood 62 has an opening on the side near the egg tray 4 to form a first cavity between the inner wall of the hood 62 and the spring sheet 51 or the clamping plate 52. For this type of height fixer 6, if a sliding component is required, the sliding component can be set between the side wall of the hood 62 and the inner wall 7 of the egg tray. To prevent the egg embryo from touching the inner wall of the first cavity and causing the egg embryo to break, a soft cushioning pad is laid on the inner wall of the hood 62. The material of the soft cushioning layer is the same as the soft cushioning layer material in the groove compensation unit, which will not be described again here.

[0039] in, Figure 1 The groove compensation unit in the egg tray shown is a spring sheet 51, and the height fixer 6 is a support frame; Figure 5 The egg tray shown in the image has a groove compensation unit consisting of a clamping plate 52 and an elastic component 53, and a height fixer 6 consisting of a cover 62. Alternatively, there may be an egg tray with a groove compensation unit consisting of a spring sheet 51 and a height fixer 6 consisting of a cover 62, or an egg tray with a groove compensation unit consisting of a clamping plate 52 and an elastic component 53, and a height fixer 6 consisting of a support frame.

[0040] This utility model also provides a vaccination device, including: an egg tray and an injection device. The injection device includes at least two injection needles, and the injection needles correspond one-to-one with the egg tray 4, so as to inject the vaccine into the egg embryo placed in the egg tray 4.
