Description

Technical Field

[0001] This utility model relates to the field of egg detection technology, specifically an egg detection device. Background Technology

[0002] Egg light testing is a non-destructive testing technology that uses the principle of light transmission to assess the quality and freshness of eggs. Its core is to judge the quality of eggs by observing the internal structural characteristics through light penetrating the eggshell. The development of this technology is directly related to the egg industry's demand for "efficient, non-destructive, and precise" quality control.

[0003] Chinese patent application number 202121407673.0 discloses an egg irradiation detection device, including a mounting box. A mounting cover is fixedly mounted on the upper end of the mounting box, and a tray is fixedly mounted on the upper end of the mounting cover. Multiple egg trays are arranged in a rectangular array. An irradiation lamp is fixedly mounted inside each egg tray. A controller is fixedly mounted on the front center of the mounting box. From right to left, a start / stop switch, an adjustment knob, and a power socket are fixedly mounted on the front of the controller. A box cover is movably mounted on the upper rear end of the mounting box via a hinge. The controller is electrically connected to the irradiation lamp and can be moved and fixed to different positions as needed for convenient use. A tray frame is fitted onto the lower outer surface of the mounting box. The connection between the mounting box and the tray frame is detachable, allowing the mounting box to be removed when not in use for easy movement.

[0004] In existing production settings, technologies like those described above often rely on manual labor to place eggs one by one into egg trays, then perform irradiation testing. After testing, the process must be repeated in reverse, removing eggs one by one from the tray's grooves and returning to the transfer box to begin a cyclical process of "egg removal-egg placement-testing-egg removal." Throughout this process, workers must maintain a posture of bending over, raising their hands, and looking down to check, which can easily lead to hand pain and decreased concentration due to prolonged repetitive labor, thereby increasing the risk of egg breakage, missed detection, and incorrect detection. Therefore, an egg testing device is proposed to address these issues. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one technical problem in the background art, this utility model proposes an egg detection device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The egg detection device of this utility model includes a sleeve and a base frame. The sleeve is fixed on the surface of the base frame. The device is characterized by including a motor, a light strip and a base frame. The motor and a detection box are fixedly connected to the surface of the base frame. The top of the detection box is an open design and several sets of light strips are fixedly connected to the inner wall. The output shaft of the motor is fixedly connected to a rotating wheel B. There are two rotating wheels B, both of which are rotatably connected to the base frame. A chain conveyor belt, the surface of which is provided with guide rails, the guide rails being engaged with the surfaces of roller B and roller A, and there are two rollers A, both of which are rotatably connected to the base frame; The surface of the chain conveyor belt is provided with a number of grooves, and the bottom of the grooves is provided with a light-shielding mechanism; The base frame is equipped with a cleaning mechanism located above the chain conveyor belt.

[0007] Preferably, the light-shielding mechanism includes a fixed block and a base plate. The fixed block is fixedly connected to the surface of the chain conveyor belt, and one end of the base plate is rotatably connected to the fixed block, while the other end is elastically connected to the fixed block via a spring.

[0008] Preferably, the inner wall of the testing box adopts a sloping design that is narrower at the bottom and wider at the top, forming an inverted T-shaped structure, with the width gradually decreasing from the bottom to the top, and the inner wall of the testing box is made of reflective material.

[0009] Preferably, the cleaning mechanism includes a fixed rod, a brush, and a housing. One end of the fixed rod is fixedly connected to the base frame, and the other end is rotatably connected to the brush. The end of the brush away from the fixed rod is rotatably connected to the housing and passes through the housing to be connected to a gear set provided on the inner wall of the housing.

[0010] Preferably, a limiting block is fixedly connected to the surface of the fixing rod, and the other end of the limiting block away from the fixing rod is fixedly connected to the surface of the box cover.

[0011] Preferably, a guide plate and a support rod are fixedly connected to the surface of the base frame, and the end of the support rod away from the base frame is fixedly connected to the guide plate.

[0012] The advantages of this utility model are: 1. When this utility model is working, the motor 9 precisely drives the rotating wheel B to rotate at a uniform speed. The rotating wheel B synchronously drives the chain conveyor belt 1 to run smoothly along the preset track. At the same time, the rotating wheel A at the other end of the chain conveyor belt 1 is driven by the operation of the chain conveyor belt 1, and then performs coordinated operation in the same direction and at the same speed, forming a continuous conveying power transmission mechanism. Then, the workers put the eggs to be sorted one by one into the grooves 11 distributed on the chain conveyor belt 1. The grooves 11 are cylindrical hollow structures. The size of these grooves 11 is adapted to the size and height of the eggs, which can firmly support the eggs and effectively prevent the eggs from shaking, shifting or even slipping during the conveying process. At this time, the chain conveyor belt 1 carrying the eggs steadily and orderly transports the eggs towards the discharge direction at the end of the system according to the set conveying speed. During the transportation of the eggs, they will accurately pass through the inspection box 5. Multiple sets of high-brightness light strips 13 are symmetrically installed on both sides inside the inspection box 5. When the eggs enter the inspection box 5 with the chain conveyor belt 1, the light will shine through the hollow at the bottom of the groove 11 to illuminate the egg shell and inside in all directions, thereby quickly and accurately completing the egg quality inspection. The entire automated conveying and inspection process greatly reduces the workload of the staff and improves the efficiency of egg inspection.

[0013] 2. In operation, when the worker gently places the egg to be tested into the cylindrical hollow groove 11 of the chain conveyor belt 1, the weight of the egg itself will be evenly applied to the movable base plate 14 at the bottom of the groove 11. Under the continuous action of the egg's gravity, the base plate 14 will overcome the slight resistance of the spring and slowly open downwards, forming a gap that matches the contour of the bottom of the egg. At this time, the bottom of the groove 11 is no longer closed, but supports the egg with an open and closed gap structure, which not only ensures the stable placement of the egg, but also reserves a channel for the penetration of light for subsequent testing. The light shines upwards through the open and closed gap of the base plate 14, evenly covering the bottom and lower half of the side of the egg, and also facilitates the worker's observation, ensuring that the quality testing of each egg is accurate. When a quality defect is detected, the light can be transmitted to the egg. Problematic eggs are promptly removed from the groove 11. The moment the egg is removed, the movable base plate 14, previously pressed down by the egg's weight, loses its downward pressure. The pre-set reset spring immediately releases its elastic potential energy, generating an upward pull. Under the stabilizing force of the spring, the movable base plate 14 quickly and smoothly resets upward until it is completely flush with the bottom of the groove 11. After the base plate 14 closes, light inside the testing chamber 5 cannot leak out through the bottom gap. This design effectively prevents strong light from directly shining into the eyes of the staff, preventing eye fatigue and blurred vision caused by strong light stimulation. This avoids visual interference affecting the subsequent judgment of egg quality, ensuring that the testing work is always carried out efficiently in a safe and clear visual environment.

[0017] 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.

[0018] Example 1 Please see Figure 1-3 As shown, an egg detection device includes a motor 9, a light strip 13 and a base frame 4. The motor 9 and a detection box 5 are fixedly connected to the surface of the base frame 4. The top of the detection box 5 is open, and several sets of light strips 13 are fixedly connected to the inner wall. The output shaft of the motor 9 is fixedly connected to a rotating wheel B8. There are two rotating wheels B8, both of which are rotatably connected to the base frame 4. Chain conveyor belt 1, the surface of chain conveyor belt 1 is provided with guide rail 2, the guide rail 2 is meshed with the surface of wheel B8 and wheel A3, there are two wheels A3, and both are rotatably connected to the base frame 4. The surface of the chain conveyor belt 1 is provided with several grooves 11, and the bottom of the grooves 11 is provided with a light-shielding mechanism; The base frame 4 is equipped with a cleaning mechanism and is located above the chain conveyor belt 1; During operation, motor 9 precisely drives wheel B to rotate at a constant speed. Wheel B synchronously drives the chain conveyor belt 1 to run smoothly along the preset track. At the same time, wheel A at the other end of the chain conveyor belt 1 is also driven by the operation of the chain conveyor belt 1, and then they work together in the same direction and at the same speed, forming a continuous conveying power transmission mechanism. Then, the workers put the eggs to be sorted one by one into the grooves 11 distributed on the chain conveyor belt 1. The grooves 11 are cylindrical hollow structures. The size of these grooves 11 is adapted to the size and height of the eggs, which can firmly support the eggs and effectively prevent the eggs from shaking, shifting or even slipping during the conveying process. At this time, the chain conveyor belt 1 carrying the eggs steadily and orderly transports the eggs towards the discharge direction at the end of the system according to the set conveying speed. During the transportation of the eggs, they will accurately pass through the inspection box 5. Multiple sets of high-brightness light strips 13 are symmetrically installed on both sides inside the inspection box 5. When the eggs enter the inspection box 5 with the chain conveyor belt 1, the light will shine through the hollow at the bottom of the groove 11 to illuminate the egg shell and inside in all directions, thereby quickly and accurately completing the egg quality inspection. The entire automated conveying and inspection process greatly reduces the workload of the staff and improves the efficiency of egg inspection.

[0019] The light-shielding mechanism includes a fixed block 12 and a base plate 14. The fixed block 12 is fixedly connected to the surface of the chain conveyor belt 1. One end of the base plate 14 is rotatably connected to the fixed block 12, and the other end is elastically connected to the fixed block 12 through a spring. During operation, when the worker gently places the egg to be tested into the cylindrical hollow groove 11 of the chain conveyor belt 1, the egg's own weight will act evenly on the movable base plate 14 at the bottom of the groove 11. Under the continuous action of the egg's gravity, the base plate 14 will overcome the slight resistance of the spring and slowly open downwards, forming a gap that matches the contour of the egg's bottom. At this time, the bottom of the groove 11 is no longer closed, but supports the egg with an open and closed gap structure, ensuring the egg is placed stably and reserving a channel for the subsequent light penetration. The light shines upwards through the open and closed gap of the base plate 14, evenly covering the bottom and lower half of the side of the egg, while also facilitating the worker's observation, ensuring that the quality inspection of each egg is accurate. If a quality problem is detected, the egg can be detected immediately. The problematic eggs will be promptly removed from the groove 11. At the moment the egg is removed, the movable base plate 14, which was originally pressed down by the weight of the egg, loses its downward pressure. The preset reset spring immediately releases its elastic potential energy, generating an upward pulling force. Under the stabilizing force of the spring, the movable base plate 14 quickly and smoothly resets upward until it is completely in contact with the bottom of the groove 11. After the base plate 14 is closed, the light inside the detection box 5 cannot leak out from the bottom gap. This design effectively prevents the strong light inside the detection box 5 from directly shining into the eyes of the staff, preventing the staff from experiencing visual fatigue or blurred vision due to strong light stimulation. This also avoids visual interference affecting the subsequent judgment of egg quality, ensuring that the detection work is always carried out efficiently in a safe and clear visual environment.

[0020] The inner wall of the testing box 5 is sloping with a narrow bottom and a wide top, forming an inverted T-shaped structure. The width gradually decreases from the bottom to the top, and the inner wall of the testing box 5 is made of reflective material. During operation, to further improve the utilization rate and accuracy of the detection light, the inner wall of detection chamber 5 is specially designed with a sloping reflective material. The surface exhibits a uniform micron-level textured surface, which not only enhances the light reflection efficiency but also avoids localized overly strong or weak reflections. Furthermore, the sloping angle of the inner wall has been calculated and adjusted to form a symmetrical sloping structure from both sides of the bottom to the center of the top of detection chamber 5, creating a funnel-like shape. The focused light space ensures that every inner wall can accurately receive the light emitted by the light strip 13. When the light inside the detection box 5 spreads outwards, some of the light shines directly on the egg, while the other part is naturally projected onto the reflective inner walls of the sloping sides. The light that comes into contact with the inner wall is immediately reflected by the highly reflective material. Due to the guiding effect of the sloping sides, these reflected lights are not scattered randomly, but are uniformly converged and refracted towards the top area of ​​the detection box 5 along the slope direction. This design provides the egg detection area at the top of the detection box 5 with sufficient and uniform light supply. Whether it is a tiny crack in the eggshell or a small foreign object inside, it can be clearly seen under strong light, greatly improving the accuracy of egg detection.

[0021] The cleaning mechanism includes a fixed rod 6, a brush 10 and a box cover 17. One end of the fixed rod 6 is fixedly connected to the base frame 4, and the other end is rotatably connected to the brush 10. The end of the brush 10 away from the fixed rod 6 is rotatably connected to the box cover 17 and passes through the box cover 17 to be connected to a gear set provided on the inner wall of the box cover 17. During operation, a brush cleaning device 10 is specially installed on the conveying path before the eggs enter the testing chamber 5. The core component of this device is multiple sets of soft and dense nylon brushes 10. The brushes 10 are distributed in a circular array on the rotating shaft, which is tightly connected to the output shaft of the motor 9 through a coupling to form a stable power transmission structure. During rotation, the soft bristles of the brushes 10 gently adhere to the surface of the egg, thoroughly cleaning the dust, feather debris, residual chicken droppings and other impurities attached to the eggshell. This prevents the lights from being blocked in the subsequent testing process, which could lead to errors in judgment by the staff. For example, black impurities on the shell might be mistaken for internal mold spots, or fine cracks might be missed due to dust. The brush cleaning completely eliminates these interfering factors, laying the foundation for accurate testing in the subsequent testing chamber 5, and ensuring that the quality judgment of each egg is based on the true and clear condition of the shell and the internal state.

[0022] The limiting block 7 is fixedly connected to the surface of the fixing rod 6, and the other end of the limiting block 7 away from the fixing rod 6 is fixedly connected to the surface of the box cover (17); During operation, to ensure the egg is thoroughly cleaned during the brush 10 cleaning stage, a limiting block 7 is installed below the working area of ​​the brush 10. The limiting block 7 fits snugly against the base plate 14, forming a stable support barrier that completely restricts the downward movement of the base plate 14. When the worker places the egg into the groove 11, even though the egg's own weight acts on the movable base plate 14, due to the support and obstruction of the limiting block 7, the base plate 14 cannot open or close downwards as it does during the detection stage, and always remains in a horizontal and stable state. At this time, the bottom of the egg can fully contact the plane of the base plate 14. Because the bottom of the egg is in close contact with the plane of the base plate 14, and the brush 10 generates a uniform lateral friction force on the egg surface, the friction force drives... As the egg begins to slowly tumble around its central axis, every part of the eggshell rotates sequentially to the contact area of ​​the brush 10, ensuring that the bristles of the brush 10 cover all corners of the eggshell, including the curved protrusions and tiny crevices on the eggshell surface. This tumbling cleaning design completely solves the problem of cleaning the bottom or sides of the egg when it is fixed in place. Whether it is dust or feather debris attached to the surface of the eggshell, or tiny impurities hidden in the crevices, they can all be thoroughly brushed away by the rotating brush 10. At the same time, the slow tumbling of the egg will not cause impact or damage to the eggshell, maintaining a stable cleaning state, ultimately achieving an all-round cleaning effect for the eggshell, clearing the way for subsequent testing.

[0023] Example 2 Please see Figure 4 As shown in the first embodiment, as another implementation of this utility model, a guide plate 15 and a support rod 16 are fixedly connected to the surface of the base frame 4, and the end of the support rod 16 away from the base frame 4 is fixedly connected to the guide plate 15. During operation, an inclined guide plate 15 is specially installed at the discharge port of the automated egg conveying and detection system. As a key connecting component for qualified eggs to transition from the chain conveyor belt 1 to the collection container, the guide plate 15 is made of food-grade PP material. This material not only has good impact resistance and wear resistance, but also avoids scratches caused by friction with the egg shell. At the same time, it meets food hygiene standards and will not contaminate the eggs. The installation angle of the guide plate 15 has been repeatedly adjusted to a 30° inclination angle with the horizontal plane below the discharge port. This ensures that the eggs can slide down smoothly by their own weight, while preventing them from colliding with each other due to excessively high rolling speed caused by an excessively large inclination angle. This creates a closed loop in the entire egg conveying, detection, and collection process, further optimizing the continuity of automated production.
