[0024] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention.

[0025] See also Figure 1-Figure 7 It should be noted that the illustrations provided in this embodiment are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components relevant to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be arbitrarily changed, and the component layout may also be more complex.

[0026] See also Figure 1 This embodiment provides a plow wing that can be used for sorting poultry eggs, such as chicken eggs. The plow wing includes a central disc 1 and at least one hook-shaped branch. The hook-shaped branch includes a connecting portion 2 and a hook-shaped portion 3. The ends of the connecting portion 2 are connected to the central disc 1 and the hook-shaped portion 3, respectively. The central disc 1 is used to drive the hook-shaped portion 3 to rotate under external force to pick up eggs. The hook-shaped portion 3 is used to pick up eggs from one conveyor belt. The connecting portion 2 is used to transfer eggs from the hook-shaped portion 3 to another conveyor belt.

[0027] When using the plow wings to sort eggs, first place the two plow wings side by side and spaced apart, then drive the two plow wings to rotate together, and at this time, the hook-shaped parts 3 of the two plow wings cooperate to pick eggs of appropriate size from the large number of eggs.

[0028] In this embodiment, the bending radius of the hook portion 3 is 38 to 55 mm. By setting the bending radius of the hook portion 3 within this range, the hook portion 3 and the radius of the egg are similar. This ensures smoother contact between the egg and the hook branch during egg retrieval, preventing collisions that could cause cracking of the egg. In other embodiments, the hook portion 3 can be set according to the size of the object being sorted.

[0029] In this embodiment, the connecting portion 2 is arc-shaped, and the bending radius of the connecting portion 2 is 270 to 330 mm. With such a configuration, the egg can roll more smoothly along the connecting portion 2, thereby avoiding the egg from breaking.

[0030] When the egg rolls along the hook-shaped branch to the transition between the hook-shaped branch and the center plate 1, in order to avoid the egg from being broken due to collision, the connection between the center plate 1 and the connecting part 2 is an arc transition with a radius of 40 to 60 mm.

[0031] In this embodiment, the cross-sectional shape of the hook-shaped branch can be circular or square, which is not limited here. When the cross-sectional shape of the hook-shaped branch is square, the end corners of the hook-shaped branch need to be chamfered.

[0032] See also Figure 2 This embodiment also provides a sorting plow, which includes a connecting rod 4 and the above-mentioned plow wings. There are at least two plow wings, and the multiple plow wings are spaced apart along the length direction of the connecting rod 4. The projections of the multiple plow wings along the length direction of the connecting rod 4 overlap. Two adjacent plow wings are used to pick eggs together, and the distance between the two adjacent plow wings is the minimum diameter of the size of the eggs to be screened.

[0033] During the implementation of the sorting plow, the sorting plow rotates under the drive of an external force. When the sorting plow passes over eggs, if the size of the egg is just larger than the distance between two adjacent plow wings, the two adjacent hook-shaped parts 3 hook the egg and sort it out from the numerous eggs. The picked egg rolls along the hook-shaped part 3 to the connecting part 2 and rolls off the plow wings from the connecting part 2, thereby completing the entire egg sorting process.

[0034] To accommodate eggs of varying sizes, the distance between adjacent plow wings is adjustable. For example, a central hole is formed in the center of the center disk 1, through which the center disk 1 is inserted onto the connecting rod 4. The center disk 1 and the connecting rod 4 are secured by welding. To adjust the distance between adjacent plow wings, the center disk 1 can be repositioned and welded again.

[0035] In another method of fixing the plow wings, a plurality of nuts are provided on the connecting rod 4 , a nut is provided on both sides of each plow wing, and each plow wing is fixed to the connecting rod 4 by two nuts.

[0036] See also Figure 3 and Figure 4This embodiment also provides an egg sorting device, which includes multiple conveying mechanisms and multiple sorting plows. The adjacent conveying mechanisms are arranged with upper and lower intervals. A sorting plow is rotatably arranged between the two adjacent conveying mechanisms. The sorting plow is used to pass through the conveying mechanism when rotating to sort the eggs on the lower conveying mechanism to the upper conveying mechanism.

[0037] There are at least two conveyor mechanisms, each arranged in parallel with the projections of adjacent conveyor mechanisms partially overlapping in height. The conveyor mechanisms are named, from bottom to top, as primary conveyor mechanism, secondary conveyor mechanism, and so on. Each conveyor mechanism comprises two baffles 5 and a plurality of belts 6 arranged side by side and spaced apart along the width of the belts 6 between the two baffles 5. The two baffles 5 are used to prevent eggs from falling from the belts 6.

[0038] There is at least one sorting plow, which includes a connecting rod 4 and a plurality of plow wings spaced apart on the connecting rod 4. The projections of the plurality of plow wings along the length direction of the connecting rod 4 overlap, and the spacing between two adjacent belts 6 on the conveying mechanism is used for one plow wing to pass through.

[0039] See also Figure 5 Specifically, the angle θ between the line connecting the center of the secondary conveyor mechanism near the end of the primary conveyor mechanism and the connecting rod 4 is 30° to 70° with the horizontal direction, and the distance D1 between the line connecting the center of the secondary conveyor mechanism near the end of the primary conveyor mechanism and the connecting rod 4 is 3 to 15 mm. To facilitate the passage of eggs between the two conveyor mechanisms, the vertical distance D2 between the two conveyor mechanisms is at least 80 mm.

[0040] See also Figure 4 The plow blades can pick up foreign matter during egg sorting. To keep these plow blades clean, the distance between two adjacent belts 6 is 60% to 90% of the plow blade width. The plow blade width refers to the width of the plow blade's hook along the conveyor's width. As the plow blades pass through the gaps between the belts 6, they scrape away foreign matter.

[0041] In this embodiment, each belt 6 is provided with multiple elastic skirts 7 on either side. These skirts 7 are spaced around the sides of the belt 6 and are rectangular blocks made of rubber. In this embodiment, the skirts 7 are 10 mm long, 7 mm wide, and 4 mm thick. The gap between adjacent skirts 7 is 1 mm to 2 mm. When the plow blades pass through the gaps between the belts 6, the elastic skirts 7 scrape away foreign matter. Furthermore, because the belts 6 are relatively soft, the plow blades cause them to tilt upwards when passing over them. At this point, the elastic skirts 7 roll the eggs toward the center of the belt 6, facilitating the plow's retrieval. When the belt 6 is provided with elastic skirts 7 on both sides, the total width of the belt 6 is calculated as: the distance between the thickness centers of two adjacent plow blades minus the plow's thickness × (60% to 90%).

[0042] See also Figure 1 and Figure 6 When sorting eggs, after the eggs slide from the sorting plow to the secondary conveyor mechanism, in order to prevent the sorting plow from continuing to rotate and getting the eggs stuck, the belt speed of the secondary conveyor mechanism should be: V≥5Rω / 2π, where R is the maximum sweep radius of the hook branch, which can range from 100mm to 500mm, and ω is the angular velocity of the sorting plow.

[0043] See also Figure 7 In the process of sorting eggs, in order to check whether the eggs have cracks, the egg sorting device also includes an X-ray imager 8 and an X-ray digital sensor 9. The X-ray imager 8 and the X-ray digital sensor 9 are respectively arranged on the upper and lower sides of the secondary conveying mechanism. When the eggs pass through the X-ray imager 8, they are photographed, and the images are recorded by the X-ray digital sensor 9 and transmitted to the computer via a USB data cable for image processing, image analysis, and crack detection. When a continuous shadow curve is detected, it is determined that the egg has a crack defect and the defective eggs are manually removed. If no shadow curve is detected, the subsequent packaging step is carried out.

[0044] In summary, the egg sorting device of this embodiment operates as follows: eggs are first placed on the primary conveyor mechanism, which then transports them toward the secondary conveyor mechanism. The sorting plow rotates continuously, and as its hooked branches pass through the primary conveyor mechanism, they pick up eggs of appropriate size. The eggs then slide along the hooked branches onto the secondary conveyor mechanism. As they pass through the X-ray imager 8 and the X-ray digital sensor 9, they are inspected for cracks. Eggs still on the primary conveyor mechanism pass through the gap between the two conveyor mechanisms, completing the egg sorting process. Therefore, the present invention effectively overcomes the shortcomings of the prior art and possesses high industrial value.

[0045] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
