[0002] Eggs, as an important food material in human daily diet, are rich in nutrients, high-quality protein, vitamins and minerals, and are an indispensable part of the dining table. The formation of eggs comes from the reproductive system of hens, which goes through multiple complex stages such as ovary development, ovulation, yolk sac and egg white formation, and eggshell formation, and is finally discharged from the body. In the production process of eggs, after the eggs are collected, they need to be washed, disinfected, sorted and packaged to ensure their hygiene quality and market value. Traditional egg sorting mostly relies on manual work, which is not only inefficient, but also prone to missed detection, false detection and other problems, affecting the quality and market competitiveness of eggs. The automatic egg sorting device is usually composed of a conveying system, a detection system and a sorting mechanism. The conveying system is responsible for conveying the eggs from the collection point to the detection area; the detection system uses optical, mechanical or AI technology to detect the eggs in all directions, identify defects such as damage, cracks, and dirt; and the sorting mechanism separates the qualified eggs from the unqualified eggs according to the detection results, achieving automatic sorting.

[0003] In the prior art, the automatic egg sorting device and manual sorting do not detect all surfaces of a single egg during detection, and there is a crack in the detection blind spot, which may cause missed detection, resulting in some eggs with large cracks and damage not being detected in time.

[0021] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0022] See Figures 1 to 3 This utility model provides an automatic egg sorting device, including a sorting box 1, a first chute 2, a second chute 3, a third chute 4, and a controller 20. The sorting box 1 has a first through hole 10 on one side, and a second through hole 11 and a third through hole 12 on the opposite side. The first chute 2 is located on the side of the sorting box 1, with one end extending into the sorting box 1 through the through hole. A rotating mechanism is located at the bottom of the sorting box 1, and a tray 21 is driven to the top of the rotating mechanism. The tray 21 is located on one side of the end of the first chute 2. A first motor 5 is located on the opposite side wall of the sorting box 1. The output shaft of the first motor 5 passes through the sorting box 1 and drives a first electric push rod 16. The telescopic end of the first electric push rod 16 is connected to a clamping mechanism, which can clamp the eggs 19 located on the tray. The second slide 3 and the third slide 4 are respectively located on both sides of the tray 21. The second slide 3 and the third slide 4 pass through the second through hole 11 and the third through hole 12 respectively and extend downwards out of the sorting box 1. The top of the sorting box 1 is provided with a moving mechanism. The bottom of the moving mechanism is provided with a second electric push rod 25. The telescopic end of the second electric push rod 25 is connected to a support plate 17. The bottom surface of the support plate 17 is provided with an ultrasonic detector 18 and a brush 31. The support plate 17 is provided with a water spray pipe 30. The water spray pipe 30 is connected to a water pump 7 through a water pipe 9. A water valve 8 is provided on the water pipe 9. The water pump 7 is located on the top surface of the sorting box 1. The controller 20 is located on the side of the sorting box 1 and is electrically connected to the first motor 5, the moving mechanism, the water pump 7, the water valve 8 and the ultrasonic detector 18.

[0023] When the sorting device is working, the egg 19 is first placed in the first chute 2. The egg 19 rolls down the top of the first chute 2 onto the tray 21 in the sorting box 1. Then, the first electric push rod 16 is activated. The telescopic end of the first electric push rod 16 extends, driving the clamping mechanism to move. The clamping mechanism abuts against both sides of the egg 19, clamping the egg 19. After the clamping mechanism clamps the egg 19, the moving mechanism is activated. The moving mechanism moves the second electric push rod 25 above the egg 19. The second electric push rod 25 is activated. The telescopic end of the second electric push rod 25 extends, driving the support plate 17 to descend. The ultrasonic detector 18 on the bottom surface of the support plate 17 detects cracks on the surface of the egg 19 in real time. At the same time, the water pump 7 and the water valve 8 are activated. The water pump 7 sprays clean water through the water pipe 9 and sprays it out from the water spray pipe 30. The sprayed water impacts the shell surface of the egg 19. At this time, the bristles 31 abut against the outer surface of the egg 19, cleaning the egg 19. Then, the first motor 5 is started. The rotation of the first motor 5 drives the first electric push rod 16 to rotate, which in turn drives the clamping mechanism to rotate, thereby causing the egg 19 to rotate. After the egg 19 has completed a predetermined number of rotations around the axis of the electric push rod 16, the clamping mechanism is released, and then the rotating mechanism is started. The rotating mechanism drives the tray 21 to rotate 90°, and then the clamping mechanism is started again. After the egg 19 has completed a predetermined number of rotations around the axis of the electric push rod 16 again, the entire surface of the egg 19 can be inspected and cleaned, avoiding blind spots in the detection of cracks and thus preventing missed detections. When the ultrasonic detector 18 detects a crack in the egg 19, the first electric push rods 16 on both sides are activated to push the egg 19 onto the third slide 4. The cracked egg 19 will roll out from the third slide 4. When the ultrasonic detector 18 detects no crack in the egg 19, the first electric push rods 16 on both sides are activated to push the egg 19 onto the second slide 3. The crack-free egg 19 will roll out from the third slide 4, thus completing the sorting of the egg 19. The sorting device uses an ultrasonic detector 18 and a brush 31 to inspect and clean the entire surface of the egg 19, avoiding blind spots in crack detection and preventing missed detections.

[0024] Preferably, the rotating mechanism includes a support platform 24 and a second motor 6. The support platform 24 is located at the bottom of the sorting box 1. A tray 21 is rotatably mounted on the top surface of the support platform 24. A receiving cavity 22 is provided inside the support platform 24. The second motor 6 is located inside the receiving cavity 22. The output shaft of the second motor 6 is connected to the tray 21. The second motor 6 is a stepper motor that can precisely control the rotation angle.

[0025] When egg 19 slides from the first chute 2 onto tray 21, the clamping mechanisms on both sides clamp egg 19. Then, the first motors 5 on both sides are started at the same time. The rotation of the first motors 5 drives the first electric push rod 16 to rotate. The rotation of the first electric push rod 16 drives the clamping mechanism to rotate, thereby rotating egg 19.

[0026] Preferably, the clamping mechanism includes an I-shaped slide rod, a helical spring 28, and a rubber pad 29. The telescopic rod of the first electric push rod 16 is provided with a groove 26. The I-shaped slide rod is slidably disposed in the groove 26. The helical spring 28 is sleeved on the I-shaped slide rod, with one end connected to the first electric push rod 16 and the other end connected to the end of the I-shaped slide rod. The helical spring 28 is used to maintain the clamping force of the rubber pad 29 on the egg 19. The rubber pad 29 is disposed on the side of the I-shaped slide rod.

[0027] After the egg 19 slides from the first slide 2 onto the tray 21, the first electric push rod 16 is activated. The telescopic end of the first electric push rod 16 extends, causing the I-shaped slide rod to move. The movement of the I-shaped slide rod causes the rubber pad 29 to abut against both sides of the egg 19. At this time, the helical spring 28 is in a compressed state, and the rubber pad 29 clamps the egg 19.

[0028] Preferably, the moving mechanism includes a lead screw 14, a third motor 23, and a moving block 15. The lead screw 14 is rotatably mounted on the top of the sorting box 1, with one end rotatably connected to the sorting box 1 and the other end passing through the sorting box 1 and driven by the third motor 23. The third motor 23 is located on the side of the sorting box 1. The moving block 15 is mounted on the lead screw 14, and the second electric push rod 25 is located on the bottom surface of the moving block 15.

[0029] The moving mechanism is used to drive the second electric push rod 25 to move, start the third motor 23, the rotation of the third motor 23 drives the lead screw 14 to rotate, the moving block 15 is screwed to the lead screw 14, the moving block 15 moves along the direction of the lead screw 14, the second electric push rod 25 is located on the bottom surface of the moving block 15, thereby moving the moving electric push rod along the direction of the lead screw 14.

[0030] Preferably, the tray 21 is cylindrical in shape and made of flexible material, and its top surface is provided with a groove.

[0031] The cylindrical shape of the tray 21 can avoid interference with the second slide 3 and the third slide 4 on both sides when rotating. The flexible material can provide cushioning when the egg 19 rolls from the first slide 2 onto the tray 21 to prevent the egg 19 from bumping. The top surface is provided with a groove to keep the egg 19 in one position.

[0032] Preferably, the water pipe 9 is a polyurethane corrugated expansion pipe.

[0033] The corrugated expansion joint has good flexibility and can adapt to the connection requirements of water pipes 9 at different positions and angles in the sorting device. During the egg sorting process, as the support plate 17 moves, the water pipes 9 need to expand and contract accordingly, and the polyurethane corrugated expansion joint can easily cope with this change.

[0034] Preferably, it also includes a support leg, which is located at the bottom of the first chute 2 and the sorting box 1.

[0035] The support legs are used to support the first chute 2 and the sorting box 1, ensuring that the sorting device remains stable during operation and avoiding shaking due to vibration or the weight of the eggs 19, thus ensuring the accuracy and efficiency of sorting.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
