Abstract
Description
Technical Field
[0001] This application relates to the field of egg production technology, and specifically discloses an egg sorting structure. Background Technology
[0002] Eggs are a common food for humans. They are rich in cholesterol and nutrients. The protein in eggs contains essential amino acids needed by the human body. The composition of these amino acids is similar to that of human amino acids, so the protein in eggs can be absorbed and utilized by the human body at a rate of over 98%, making them highly nutritious.
[0003] In the egg production process, eggs laid by hens are usually collected, packaged, and then distributed to the market. However, in the current egg market, eggs are typically graded according to their weight before being sold, with eggs weighing around 50 grams considered the best quality. Therefore, before packaging, the eggs need to be screened to facilitate distribution in the market.
[0004] Existing egg sorting methods rely on manual observation, which is inefficient, inaccurate, and can negatively impact egg production quality. Therefore, the inventors have developed an egg sorting structure to address these issues. Utility Model Content
[0005] The purpose of this invention is to solve the problem that traditional egg sorting based on manual observation is inefficient and the inaccurate sorting results can easily affect the quality of sold eggs.
[0006] To achieve the above objectives, the basic solution of this utility model provides an egg sorting structure, including an egg sieve box for sorting eggs, several egg storage boxes arranged linearly and detachably installed inside the egg sieve box, a belt conveyor located inside the egg sieve box for transporting eggs, and a controller. The egg storage boxes are located at the end of the belt conveyor. A transfer platform is slidably connected to the inner wall of the egg sieve box near the end of the belt conveyor. A linear motion module for moving the transfer platform between the end of the belt conveyor and the egg storage boxes is installed on one side wall of the egg sieve box. A support plate for placing eggs is provided on the transfer platform. A gravity sensor for detecting the weight of the eggs on the support plate is provided between the support plate and the transfer platform. An electric telescopic pusher is provided on one side of the transfer platform for pushing the eggs on the support plate into the egg storage boxes. The gravity sensor and the electric telescopic pusher are both electrically connected to the controller. Each egg storage box is also provided with a vertical egg loading assembly for individually loading each egg in the egg storage box.
[0007] The principle and effect of this basic scheme are as follows:
[0008] 1. Compared with the prior art, this utility model facilitates the automatic conveying and transfer of eggs by setting up a controller, an electric telescopic rod push plate, a linear motion module, a belt conveyor and a transfer platform.
[0009] 2. Compared with the existing technology, this utility model, by setting up multiple egg storage boxes, a support plate on the transfer platform, and a gravity sensor, facilitates the weight detection of eggs, thereby enabling the classification of eggs into weight classes based on their weight. This allows for the sorting and storage of eggs in different weight classes, resulting in more accurate weight measurement results and faster sorting. This greatly improves the efficiency and quality of egg sorting, and facilitates egg packaging and export. It solves the problem that traditional egg sorting based on manual observation is inefficient and inaccurate, which can easily affect the quality of sold eggs.
[0010] Furthermore, each egg storage box is equipped with a feeding inlet on the side near the transfer platform. A feeding door is hinged to the top of each feeding inlet, and one side of the feeding door is detachably snapped onto the outside of the egg storage box. An inclined guide plate, connected to the bottom of the feeding door, is located at the end of the transfer platform near the feeding inlet. The end of the inclined guide plate is also connected to the end of the belt conveyor. The bottom side of the electric telescopic pusher is slidably connected to the upper surface of the support plate, and the top of the electric telescopic pusher is not higher than the top of the feeding inlet. By providing feeding inlets and feeding doors, channels are provided for loading and unloading eggs. The inclined guide plate and the height limit of the electric telescopic pusher facilitate the guidance and pushing of eggs into the egg storage box.
[0011] Furthermore, the vertical egg-packing assembly includes several egg-packing bags that can be stacked inside the egg storage box to hold individual eggs, several connecting ropes for vertically connecting two adjacent egg-packing bags, and a limiting plate that is slidably connected to the inner wall of the egg storage box and located above the topmost egg-packing bag inside the egg storage box. Each end of the egg-packing bag has symmetrically arranged guide rods that can be slidably connected to the inner walls of both sides of the egg storage box. The two ends of the limiting plate are also connected to the topmost egg-packing bag inside the egg storage box by several connecting ropes. A lifting assembly for raising and lowering the limiting plate is located between the top of the limiting plate and the top of the egg storage box. The two ends of the limiting plate can be engaged with the sides of the inner top of the egg storage box. By setting up the egg-packing bags, connecting ropes, and limiting plate, it is convenient to place eggs individually. By setting up the connecting ropes, limiting plate, and lifting assembly, it is convenient to vertically separate eggs of the same weight class within the same egg storage box, ensuring clear sorting.
[0012] Furthermore, the egg-holding bag includes a flexible cloth pouch connected between two symmetrical guide rods for containing the eggs, and side meshes connected between the two ends of the symmetrical guide rods and symmetrically located at both ends of the flexible cloth pouch. By providing the flexible cloth pouch and side meshes, the eggs are easily contained and placed while their structural integrity is protected.
[0013] Furthermore, the lifting assembly includes a mounting base detachably mounted on the top of the egg storage box, lifting machines symmetrically and detachably mounted on the mounting base and located directly above both ends of the limiting plate, lifting ropes that can be wound and limited on the two lifting machines respectively and detachably connected to the top of the limiting plate through the bottom of the mounting base and the top of the egg storage box, and a drive motor detachably mounted on the outer end of the mounting plate for driving the lifting machines to rotate. The drive motor is electrically connected to the controller. A connecting shaft is coaxially connected between the two lifting machines located on the mounting base. The outer end of the central shaft of any one of the lifting machines located on the mounting base is coaxially connected to the output end of the drive motor. The bottom of the mounting base and the top of the egg storage box are symmetrically provided with rope-passing grooves that allow the lifting ropes to pass through. By setting a drive motor coaxially to drive two lifting machines to rotate, the lifting rope between the limit plate and the lifting machine can be adjusted to achieve sliding and lifting movement of the limit plate and all egg bags in the egg storage box, which facilitates the loading and unloading of eggs. At the same time, by setting a detachable connection between the mounting base and the egg storage box, it is easy to directly disassemble the mounting base and the lifting machine after the current egg storage box reaches the storage capacity, and cut and tie the lifting rope at the outer end of the egg storage box. This facilitates the delivery of the egg storage box and the sale of eggs, and also facilitates the reuse of the lifting components, which is flexible.
[0014] Furthermore, the limiting plate has symmetrically arranged locking grooves at both ends on one side, and locking springs are provided on the inner end faces of the locking grooves. The free ends of the locking springs are provided with locking blocks that are slidably connected to the locking grooves. The tops of both ends of the egg storage box are symmetrically provided with locking slots that allow the locking blocks to pass through. By setting the locking blocks, locking springs, and locking slots, it is easy to lock and fix the limiting plate when it rises to its highest position, thereby facilitating the vertical positioning of the limiting plate and each egg bag.
[0015] Furthermore, the inner walls on both sides of the egg storage box are symmetrically provided with guide grooves at both ends, and the guide rod is slidably connected to the guide groove. The top of one of the guide grooves is also connected to the snap-fit groove. By providing guide grooves, it is convenient to provide lifting and sliding limit for the guide rod, making the structure of the limit plate and the egg bag more stable during the lifting process.

[0023] An egg sorting structure, implementing, for example Figure 1 The system includes an egg sieving box 2 for sorting eggs 1, multiple egg storage boxes 3 arranged linearly along the longitudinal direction of the egg sieving box 2 and detachably installed inside the egg sieving box 2, a belt conveyor 4 located inside the egg sieving box 2 for transporting eggs 1, and a controller, including but not limited to a PLC controller. The egg storage boxes 3 are located at the front end of the belt conveyor 4. A transfer platform 5 is slidably connected to the inner wall of the egg sieving box 2 near the end of the belt conveyor 4. A linear motion module 6 is installed on the right inner wall of the egg sieving box 2 to drive the transfer platform 5 to move between the end of the belt conveyor 4 and the egg storage boxes 3. The conveyor 4 directly uses existing equipment. The transfer table 5 is equipped with a support plate 7 for placing eggs 1. A gravity sensor 8 is installed between the support plate 7 and the transfer table 5 to detect the weight of the eggs 1 on the support plate 7. An electric telescopic pusher 9 is installed on the right side of the transfer table 5 to push the eggs 1 on the support plate 7 into the egg storage box 3. The gravity sensor 8 and the electric telescopic pusher 9 are both electrically connected to the controller. The number of egg storage boxes 3 is determined according to the weight classification requirements of the egg 1 manufacturers when exporting. Each egg storage box 3 is also equipped with a vertical egg loading component for individually packing each egg 1 in the egg storage box 3.
[0024] Among them, such as Figure 1 and Figure 2 As shown, each of the egg storage boxes 3 has a feed inlet 10 on the side near the transfer platform 5. The top of the feed inlet 10 is hinged to a feed door 11. One side of the feed door 11 is detachably snapped to the outside of the egg storage box 3. The end of the transfer platform 5 near the feed inlet 10 is provided with an inclined guide plate 12 that is connected to the bottom end of the feed door 11.

Both ends of the egg-filling bags 13 are symmetrically provided with guide rods 16 that can be slidably connected to the inner walls of both sides of the egg storage box 3. Both ends of the limiting plate 15 are also connected to the topmost egg-filling bag 13 inside the egg storage box 3 by four connecting ropes 14. A total of thirty-two connecting ropes 14 are required in one set of vertical egg-filling assemblies. A lifting assembly for driving the limiting plate 15 to rise and fall is provided between the top of the limiting plate 15 and the top of the egg storage box 3. Both ends of the limiting plate 15 can be snapped into the side of the inner top of the egg storage box 3.
[0026] Among them, such as Figure 2 As shown, the egg bag 13 includes a flexible cloth bag 17 connected between two symmetrical guide rods 16 and used to contain the egg 1, and side nets 18 connected between the two ends of the two symmetrical guide rods 16 and symmetrically located at both ends of the flexible cloth bag 17.
[0027] Among them, such as Figure 3 As shown, the lifting assembly includes a mounting base 19 detachably mounted on the top of the egg storage box 3, lifting machines 20 symmetrically and detachably mounted on the mounting base 19 and located directly above both ends of the limiting plate 15, lifting ropes 29 that can be wound and limited on the two lifting machines 20 respectively and pass through the bottom of the mounting base 19 and the top of the egg storage box 3 and are detachably connected to the top of the limiting plate 15, and a drive motor 21 detachably mounted on the outer end of the mounting plate for driving the lifting machines 20 to rotate. The drive motor 21 is electrically connected to the controller. A connecting shaft 22 is coaxially connected between the two lifting machines 20 located on the mounting base 19. The outer end of the central shaft of any one of the lifting machines 20 located on the mounting base 19 is coaxially connected to the output end of the drive motor 21. The bottom of the mounting base 19 and the top of the egg storage box 3 are symmetrically provided with rope-passing grooves 23 for the lifting ropes 29 to pass through.
[0028] Among them, such as Figure 4 As shown, the rear ends of the limiting plate 15 are symmetrically provided with snap-fit grooves 24, and the inner end face of each snap-fit groove 24 is provided with a snap-fit spring 25. The free end of the snap-fit spring is provided with a snap-fit block 26 that is slidably connected to the snap-fit groove 24. The top of both ends of one side of the egg storage box 3 is symmetrically provided with snap-fit through slots 27 that allow the snap-fit blocks 26 to pass through. The snap-fit connection method between the feed door 11 and the egg storage box 3 includes, but is not limited to, the same snap-fit connection method between the limiting plate 15 and the egg storage box 3.
[0029] Among them, such as Figure 3 As shown, the two ends of the inner walls on both sides of the egg storage box 3 are symmetrically provided with guide grooves 28, and the guide rod 16 is slidably connected to the guide grooves 28. The top of the guide groove 28 on the rear side is also connected to the locking groove 27.
[0030] In the specific implementation of this utility model, before sorting the eggs 1, the feeding doors 11 of each egg storage box 3 are opened, and the controller controls the linear motion module 6 to drive the transfer table 5 to slide to the right end of the belt conveyor 4, and the inclined guide plate 12 is connected to the rightmost end of the belt conveyor 4 and then stopped. This point is used as the initial point of the transfer table 5. Next, the limiting plate 15 in each egg storage box 3 needs to be lifted and adjusted. The controller controls the drive motor 21 to rotate forward, so that the lifting rope 29 is wound into the elevator 20 until the first egg bag 13 below the limiting plate 15 is lower than the bottom of the feeding port 10 and the height difference between the egg bag 13 and the feeding port 10 does not exceed the thickness of the limiting plate 15. During this process, the two ends of the limiting plate 15 slide upward along the guide groove 28, thus completing the preparation work before sorting the eggs 1.
[0031] During the sorting of eggs 1, eggs 1 are intermittently placed on the leftmost end of the belt conveyor 4 and transported to the rightmost end. Eggs 1 roll off the rightmost end of the belt conveyor 4 onto the support plate 7 on the transfer table 5. The gravity sensor 8 at the bottom of the support plate 7 detects the gravity of the eggs 1 on the support plate 7 and feeds the gravity data of the eggs 1 back to the controller. The controller, based on the preset weight grouping of eggs 1 and the position of the corresponding egg storage box 3, further controls the linear motion module 6 to slide to the position of the corresponding egg storage box 3 and stop. Then, the controller controls the electric telescopic pusher 9 to extend and provide a pushing force to the eggs 1 on the support plate 7, pushing the eggs 1 from the feed inlet 10 into the egg storage box 3 and into the flexible cloth bag 17 of the egg bag 13. The controller controls the drive motor 21 at the top of the egg storage box 3 to rotate forward, causing the lifting rope 29 to be wound into the elevator 20 until the nearest empty egg bag 13 located below the egg bag 13 rises to a position below the bottom of the inlet 10, ensuring that the height difference between the empty egg bag 13 and the inlet 10 does not exceed the thickness of the limiting plate 15. At the same time, after the egg 1 leaves the support plate 7, the detection result of the gravity sensor 8 returns to its original state, and the controller controls the linear motion module 6 to drive the transfer table 5 to slide to the initial position, waiting for the belt conveyor 4 to continue to transport the next egg 1 to the transfer table 5. This process continues until the limiting plate 15 inside any egg storage box 3 reaches the top of the egg storage box 3. At this point, the inlet door 11 of the egg storage box 3 is closed, and a new egg storage box 3 is replaced for backup.
[0032] When replacing the egg storage box 3, the connection constraint between the mounting base 19 and the egg storage box 3 must first be removed. Then, the controller drives the drive motor 21 to reverse and release the lifting rope 29. At the same time, the mounting base 19 and all structures on the mounting base 19 are lifted upward. When the length of the released rope 29 is equal to the length of a connecting rope 14, the lifting rope 29 of the elevator 20 is cut. At the same time, the part of the lifting rope 29 connected to the egg storage box 3 is knotted at the top of the outer side of the egg storage box 3 for limiting and securing. The knot length should ensure that the limiting plate 15 abuts against the top of the inner side of the egg storage box 3. Then, the entire egg storage box 3 is removed from the egg sieving box 2, and the new empty egg storage box 3 is installed in the same position in the egg sieving box 2. The mounting base 19 is then installed on the top of the newly installed egg storage box 3, and a new round of egg 1 sorting work begins.
[0033] Compared with existing technologies, this utility model facilitates the automatic conveying and transfer of eggs 1 by setting up a controller, an electric telescopic push plate, a linear motion module 6, a belt conveyor 4, and a transfer platform 5. By setting up multiple egg storage boxes 3, a support plate 7 on the transfer platform 5, and a gravity sensor 8, it facilitates weight detection of eggs 1, enabling them to be classified into weight classes based on their weight. This allows for sorting and storing eggs 1 in egg storage boxes 3 according to different weight classes, resulting in more accurate weight measurement and faster sorting. This significantly improves the efficiency and quality of egg sorting, facilitating packaging and export of eggs 1. It solves the problem of low efficiency and inaccurate sorting results that traditional egg selection based on manual observation can negatively impact the quality of sold eggs. 。
