Description

Technical Field

[0001] This utility model relates to the field of dark spot egg detection technology, and in particular to a device for detecting dark spot eggs in eggs. Background Technology

[0002] Eggshell quality is a crucial economic and aesthetic factor for eggs, and eggshell problems are common in laying hen production, causing significant economic losses annually. Dark-spotted eggs, also known as translucent eggs, are eggs that develop light brown spots on their shells after a certain period of time, influenced by factors such as temperature and humidity. These spots are generally undetectable within the first few hours after laying, can be detected by candling after 2-3 days at room temperature, and become clearly visible to the naked eye after 7 days. Dark-spotted eggs severely impact the appearance of eggs, affecting consumer demand and reducing sales of branded eggs. Furthermore, these spots increase the likelihood of contamination with harmful bacteria such as Salmonella and E. coli during storage, significantly reducing shelf life, causing substantial economic losses, and hindering the sustainable development of the laying hen industry.

[0003] However, in actual research and production, the shape and location of dark spots are irregular and vary greatly, making evaluation difficult. Although it is known that dark-spotted eggs are common in the market, there is no unified evaluation method due to inconsistent methods, making market control difficult.

[0004] Current evaluation methods are based on the degree of light transmittance of eggs under light. This method has a significant discrepancy between the evaluated dark spot occurrence and the actual occurrence rate (due to differences in storage conditions, eggs with high light transmittance under light do not necessarily have a high rate of dark spots). Furthermore, existing methods (the currently more commonly used 6-level system only refers to light transmittance under light and does not consider differences observed by the naked eye under natural light) have obvious drawbacks such as being subjective, inaccurate, difficult to evaluate, and cumbersome, and are not widely used. Utility Model Content

[0005] The technical problem to be solved by this invention is to provide a device for detecting dark spots in eggs, so as to overcome the shortcomings of the prior art.

[0006] Technical Solution: To achieve the above objectives, this utility model is implemented through the following technical solution: A device for detecting dark spots in eggs, comprising: a first ring and a second ring, the central axes of the first ring and the second ring being coincident, the diameter of the first ring being larger than the diameter of the second ring, the first ring and the second ring being used to divide the egg into three parts, namely the tip, the blunt end and the equatorial part, so as to detect and evaluate dark spots in the tip, blunt end and equatorial part regions respectively. The first ring and the second ring are the core components of the device, and their material is made of transparent and strong material, such as transparent acrylic, which facilitates the observation of dark spots in different parts of the egg and ensures the durability of the device.

[0007] In a further embodiment, extension blocks are respectively disposed on the same side of the first ring and the second ring; a support block is located between the two extension blocks, and the support block is used for the connection between the two extension blocks. One end of the support block is connected to the extension block on the first ring. The extension block is designed to be cuboid in shape, and its length is adjusted according to actual needs to ensure that the support block can be stably connected between the two rings. During installation, the extension block and the ring are seamlessly welded to ensure the firmness of the connection and avoid loosening during use.

[0008] In a further embodiment, the slider is slidably connected within the support block. One end of the slider passes through the support block, and the other end is connected to an extension block on the second ring. The slider is slidably connected within the support block using a dovetail groove structure, which effectively prevents the slider from wobbling or shifting during sliding. When the slider is connected to the extension block on the second ring, a detachable connection method, such as a bolt connection, is used to facilitate replacement if the slider or other components are damaged.

[0009] In a further embodiment, one end of the pressing block is slidably connected to an extension block on the first ring. The pressing block is located at the end of the support block away from the egg. The pressing block is used to control the movement of the second ring. The pressing block is designed in accordance with ergonomic principles, and its surface is provided with anti-slip texture, such as a wave-shaped texture, to facilitate operation by pressing with the fingers, increasing friction and preventing slippage during operation. When the pressing block is slidably connected to the extension block on the first ring, a linear guide rail structure is adopted to ensure the stability and straightness of the pressing block during movement.

[0010] In another embodiment, a diagonal rod is positioned between the support block and the pressing block. One end of the diagonal rod is rotatably connected to the pressing block, and the other end is slidably connected within the support block. A push block is connected to the other end of the diagonal rod and slidably connected within the support block. The push block is used to push the slider to move. The rotatable connection between the diagonal rod and the pressing block is a pin connection. The surface of the pin is hardened to improve its hardness and wear resistance. The connection between the other end of the diagonal rod and the push block is integrally formed to ensure the strength of the connection and prevent breakage during the pushing of the slider. The inclination angle of the diagonal rod is optimized to ensure that the slider can be pushed to move with minimal force when pressing the pressing block.

[0011] In a further embodiment, a spring is disposed between the support block and the pressing block. One end of the spring is connected to the support block, and the other end is connected to the pressing block. The spring is used to reset the pressing block. The spring is a compression spring made of stainless steel, which has good elasticity and corrosion resistance and can maintain stable performance during long-term use. Spring seats are provided at both ends of the spring. The spring seats are fixed to the support block and the pressing block by welding or threaded connection to ensure that the spring will not be displaced during operation.

[0012] In a further embodiment, the diagonal rod is inclined as a whole and does not interfere with the spring.

[0013] In a further embodiment, the evaluation criteria for the tip and blunt end are as follows: no dark spots, a few dark spots, very light-colored dark spots less than 5, a few dark spots that are scattered, very light-colored dark spots less than 10, and a large number of dark spots, with obvious dark spots and more than 10, which are respectively scored as 0, 1, 2, and 3 points. For the judgment of the dark spot color, a standard color card is established as a reference. The color on the standard color card is compared with the dark spot color to determine the depth of the dark spot color. In the actual testing process, the testers need to observe under specific lighting conditions.

[0014] In a further embodiment, the evaluation criteria for the equatorial portion are: a small number of dark spots that are scattered and have a very light color and a number of less than 10, and a large number of dark spots that have a distinct color and a number of more than 10, which are respectively scored as 2 points and 3 points. During the detection process, the observation must be carried out under the same lighting conditions as the detection of the tip and the blunt end.

[0015] In a further embodiment, the rating criteria for the tip, blunt end, and equator are as follows: no dark spots at the tip, blunt end, and equator; a small number of dark spots at the tip, blunt end, and equator with very light color; and a significant dark spot at one of the tip, blunt end, and equator, respectively, which are recorded as Grade 1, Grade 2, and Grade 3.

[0016] Beneficial effects: 1. This device precisely divides the egg into three regions—the pointed end, the blunt end, and the equatorial portion—using a first and a second ring with coincident central axes but different diameters. This allows for separate dark spot detection in each region. This zoned detection method avoids detection errors caused by differences in dark spot distribution across different parts of the egg, significantly improving the accuracy of dark spot detection compared to previous methods that rely on overall fuzzy detection. For example, the eggshell structure and composition vary slightly in different parts, resulting in different probabilities and characteristics of dark spots. Zoned detection can capture these differences more precisely, providing a strong guarantee for accurate subsequent evaluation of egg quality.

[0017] 2. The device is equipped with extension blocks, support blocks, sliders, pressing blocks, inclined rods, push blocks, and springs, which work together to facilitate the handling of eggs. Operators only need to press the pressing block to push the slider through the inclined rods and push blocks, which in turn moves the second ring to fix and partition the eggs. The operation is simple and convenient.

[0018] 3. This device has established scientific and detailed evaluation standards for dark spots at the tip, blunt end, and equatorial part, covering multiple dimensions such as the presence, quantity, color depth, and distribution of dark spots, and scores are made accordingly. At the same time, there is also a rating standard that integrates the scores of each part to classify eggs into different grades. This scientific evaluation and rating system provides an objective and quantitative basis for judging egg quality. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in this utility model are described clearly and completely. Obviously, the described embodiments are only some, not all, of the embodiments in this utility model. All other embodiments obtained by those skilled in the art based on the embodiments in this utility model without creative effort are within the scope of protection of this utility model.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] Reference Figure 1-5 A device for detecting dark spots in eggs includes: a first ring 1 and a second ring 2, the central axes of the first ring 1 and the second ring 2 coincide, the diameter of the first ring 1 is larger than the diameter of the second ring 2, the first ring 1 and the second ring 2 are used to divide the egg into three parts, namely the tip, the blunt end and the equatorial part, so as to detect and evaluate dark spots in the tip, the blunt end and the equatorial part respectively.

[0029] This technology enables precise division of an egg into three regions: the pointed end, the blunt end, and the equatorial region. This lays the foundation for accurate dark spot detection and evaluation of each region, improving the targeting and accuracy of the detection.

[0030] Extension blocks 3 are respectively disposed on the same side of the first ring 1 and the second ring 2; support block 4 is located between the two extension blocks 3, and the support block 4 is used for the connection between the two extension blocks 3. One end of the support block 4 is connected to the extension block 3 on the first ring 1.

[0031] It achieves a stable connection between the first ring 1 and the second ring 2. Through the cooperation of the extension block 3 and the support block 4, the stability of the overall structure of the device is enhanced, ensuring that the relative position of the two rings is fixed during the detection process, thus guaranteeing the reliability of the detection.

[0032] The slider 401 is slidably connected inside the support block 4. One end of the slider 401 passes through the support block 4 and the other end is connected to the extension block 3 on the second ring 2.

[0033] This achieves the effect of enabling relative movement between the first ring 1 and the second ring 2. The slider 401 slides within the support block 4 and connects the extension blocks 3 of the two rings, providing a mechanical connection basis for subsequently controlling the movement of the second ring 2 through the pressing block 5.

[0034] The pressing block 5 is slidably connected at one end to the extension block 3 on the first ring 1. The pressing block 5 is located at the end of the support block 4 away from the egg. The pressing block 5 is used to control the movement of the second ring 2.

[0035] This achieves convenient control of the movement of the second ring 2. Operators can easily adjust the position of the second ring 2 by operating the pressing block 5, thus improving the ease of operation of the device.

[0036] The inclined rod 7 is located between the support block 4 and the pressing block 5. One end of the inclined rod 7 is rotatably connected to the pressing block 5, and the other end is slidably connected to the support block 4. The push block 701 is connected to the other end of the inclined rod 7 and slidably connected to the support block 4. The push block 701 is used to push the slider 401 to move.

[0037] This effectively converts the movement of the pressing block 5 into the movement of the slider 401. The coordinated work of the inclined rod 7 and the push block 701, utilizing the lever principle and sliding connection, enables the movement of the slider 401 to be precisely controlled by the minute movements of the pressing block 5, thereby improving the operating accuracy and mechanical efficiency of the device.

[0038] A spring 6 is disposed between the support block 4 and the pressing block 5. One end of the spring 6 is connected to the support block 4, and the other end is connected to the pressing block 5. The spring 6 is used to reset the pressing block 5.

[0039] The automatic reset function of the pressing block 5 is achieved. The spring 6 allows the pressing block 5 to automatically return to its initial position after being pressed, which facilitates the operator to perform the next inspection operation and improves the continuity and efficiency of the inspection process.

[0040] The inclined rod 7 is tilted as a whole and does not interfere with the spring 6.

[0041] This ensures that all internal components of the device operate normally without interfering with each other. The inclined design of the diagonal rod 7 and its layout that does not interfere with the spring 6 avoid collisions and jamming between components during the operation of the device, thus ensuring the stability and reliability of the device operation.

[0042] The evaluation criteria for the tip and blunt end are as follows: no dark spots, a few dark spots, very light-colored dark spots with a number of less than 5, a few dark spots that are scattered, very light-colored dark spots with a number of less than 10, and a large number of dark spots, with obvious dark spots and a number of more than 10, and are respectively scored as 0 points, 1 point, 2 points and 3 points.

[0043] This method achieves the effect of quantitative evaluation of dark spots at the tip and blunt end of eggs. The clear evaluation criteria provide a unified basis for judgment for testers, and the test results of dark spots at the tip and blunt end of eggs can be presented intuitively in the form of scores, which is convenient for subsequent statistics and analysis.

[0044] The evaluation criteria for the equatorial region are as follows: a small number of dark spots that are scattered and very light in color, with a number of less than 10, and a large number of dark spots that are obvious in color and more than 10, are scored as 2 points and 3 points respectively.

[0045] This method enables a quantitative assessment of dark spots on the equator of an egg, echoing the evaluation criteria for the pointed and blunt ends. It provides a comprehensive and unified quantitative assessment method for the detection of dark spots on eggs, which helps to accurately determine the condition of dark spots on the equator of an egg.

[0046] The rating criteria for the tip, blunt end, and equator are as follows: no dark spots at the tip, blunt end, and equator; a small number of dark spots at the tip, blunt end, and equator, with very light color; and a significant dark spot at one of the tip, blunt end, and equator, respectively, which are recorded as Grade 1, Grade 2, and Grade 3.

[0047] This method achieves a comprehensive rating of the overall dark spot condition of eggs. By taking into account the dark spots at the tip, blunt end, and equatorial region, eggs are classified into different grades, providing a simple and intuitive result for the overall evaluation of egg quality. This facilitates the classification and quality control of eggs in actual production and sales.

[0048] During use, the operator first holds the device and presses the pressing block 5 towards the support block 4. At this time, the inclined rod 7 rotates as the pressing block 5 moves. The push block 701 at the other end of the inclined rod 7 slides in the support block 4 and pushes the slider 401 away from the first ring 1. The slider 401 drives the second ring 2 upward. Next, the egg to be tested is placed in the first ring 1. Then, the pressing block 5 is released. Under the action of the spring 6, the pressing block 5 returns to its original position, driving the inclined rod 7 and the push block 701 back to their initial positions. The second ring 2 moves downward until it contacts the egg, thus dividing the egg into three parts: the pointed end, the blunt end, and the equatorial part. Finally, the inspector observes the dark spots on the pointed end, the blunt end, and the equatorial part of the egg according to the preset evaluation criteria. The inspector judges and scores the presence, quantity, color depth, and distribution of the dark spots. Then, the overall dark spot condition of the egg is comprehensively rated according to the rating criteria to determine whether the egg is a dark spot egg and its grade.

[0049] The figures shown in the accompanying drawings are illustrative and are intended only to more intuitively demonstrate the key structure and connection relationships of the device for detecting dark spots in eggs according to this invention. In practical applications, the appearance and size of the device can be adjusted and optimized according to specific needs.

To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits have not been described in detail.
