Description

Technical Field

[0001] This utility model relates to the field of vegetable sorting technology, specifically to an automatic vegetable sorting device. Background Technology

[0002] In modern society, consumers have increasingly higher demands for vegetable quality. They expect the vegetables they buy to be not only fresh and undamaged, but also highly consistent in size and maturity. For example, in supermarkets, neatly arranged, high-quality vegetables are more popular with consumers. This demand has prompted the vegetable industry to seek more efficient and precise sorting methods.

[0003] With the continuous advancement of agricultural scale and industrialization, vegetable production has increased significantly. Large-scale vegetable planting bases have a large amount of vegetables that need to be sorted and processed for sale every day, but traditional manual sorting methods are inefficient and can no longer meet the needs of large-scale vegetable processing. For example, during the harvest season, a large number of vegetables are put on the market at once, and the speed of manual sorting is far from keeping up with the speed of vegetable production. At the same time, during the sorting process, it is impossible to effectively remove impurities from the vegetables, making sorting extremely inconvenient.

[0004] Therefore, there is an urgent need for an automatic vegetable sorting device to solve the problem of the inconvenience of sorting large quantities of vegetables. Utility Model Content

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] As attached Figure 1As shown, an automatic vegetable sorting device according to an embodiment of the present invention includes a sorting equipment frame 14, a multi-stage vibrating conveyor structure, an identification and sorting structure, a good product conveying structure, and a defective product conveying structure. The sorting equipment frame 14 has a stepped structure. The multi-stage vibrating conveyor structure is movably arranged on each step of the stepped structure. The vibrating conveyor structure includes a conveyor plate and a vibrating motor. The conveyor plate is movably connected to each step of the stepped structure. A vibrating motor is installed on each step. The output end of the vibrating motor is connected to the bottom of the conveyor plate and is used to drive the conveyor plate to vibrate. The conveyor plate is provided with filter holes. The conveyor plate on the adjacent higher step is inclined at a 5-degree angle to the conveyor plate on the lower step. The conveyor plate located on the second lowest step is inclined to the identification and sorting structure on the same step. The identification and sorting structure is used to receive vegetables from the conveyor plate on the second lowest step and sort and convey them to the good product conveying structure or the defective product conveying structure. The good product conveying structure and the defective product conveying structure are located at the lowest step of the sorting equipment frame 14.

[0027] This invention utilizes a vibrating conveyor structure with interconnected conveyor plates as the input structure for vegetables. During the input process, a slope from high to low, combined with a vibrating motor, effectively removes dirt and other impurities adhering to the vegetables. Simultaneously, filter holes on the conveyor plates separate fallen impurities to the area below, ensuring effective separation of impurities from the vegetables. The vibrating motor also accelerates the movement of the vegetables, increasing sorting efficiency. The stepped structure of the multi-stage vibrating conveyor structure and the sorting equipment frame 14 allows for the configuration of the required levels of the vibrating conveyor structure, enabling adjustments to the vibration interval length to effectively control and ensure impurity removal. By recognizing the coordination between the sorting and conveying structures, automated vegetable desoiling and sorting operations are achieved, ensuring both convenience and efficiency in sorting.

[0028] As attached Figure 2As shown, in another specific embodiment, the vibration conveying structure has three levels, including a primary conveyor plate, a primary vibration motor 21, a secondary conveyor plate, a secondary vibration motor 20, a tertiary conveyor plate, and a tertiary vibration motor 19. The primary conveyor plate is movably installed on the highest fourth level 29 of the stepped structure of the sorting equipment frame 14. The primary vibration motor 21 is installed on the fourth level 29 and is connected to the bottom of the primary conveyor plate. The secondary conveyor plate is movably installed on the second highest third level 28 of the stepped structure of the sorting equipment frame 14. The secondary vibration motor 20 is installed on the third level 28 and is connected to the bottom of the secondary conveyor plate. The tertiary conveyor plate is movably installed on the second lowest second level 27 of the stepped structure of the sorting equipment frame 14. The tertiary vibration motor 19 is installed on the second level 27 and is connected to the bottom of the tertiary conveyor plate. The primary conveyor plate is inclined toward the secondary conveyor plate, the secondary conveyor plate is inclined toward the tertiary conveyor plate, and the tertiary conveyor plate is inclined toward the identification and sorting structure.

[0029] In a further embodiment, the primary and secondary conveyor plates are hinged to the sorting equipment frame 14 on the side closest to the lower level, with the primary conveyor plate positioned above the secondary conveyor plate. The tertiary conveyor plate is hinged to the sorting equipment frame 14 on the side furthest from the identification and sorting structure, with the secondary conveyor plate positioned above the tertiary conveyor plate on the side closest to it. This design ensures structural stability while maintaining vibration control, and prevents the identification and sorting structure from being affected by the vibration of the tertiary conveyor plate.

[0030] In a further embodiment, a primary conveyor plate has primary guardrails 1 on both sides, and several primary conveying troughs 3 are formed on the upper surface of the primary conveyor plate. Primary conveying baffles 4 are positioned between the primary conveying troughs 3, and primary filter holes 2 penetrate vertically on each primary conveying trough 3. A secondary conveyor plate has secondary guardrails 5 on both sides, and several secondary conveying troughs 7 are formed on the upper surface of the secondary conveyor plate. Secondary conveying baffles 8 are positioned between the secondary conveying troughs 7, and secondary filter holes 6 penetrate vertically on each secondary conveying trough 7. A tertiary conveyor plate has tertiary guardrails on both sides, and several tertiary conveying troughs are formed on the upper surface of the tertiary conveyor plate. Tertiary conveying baffles are positioned between the tertiary conveying troughs, and tertiary filter holes penetrate vertically on each tertiary conveyor trough. Thus, through the arrangement of the primary conveying troughs 3, 2nd, and 3rd conveying troughs, as well as the primary, 2nd, and 3rd conveying baffles 4, 8, and 9, messy vegetables can be effectively separated and sorted, gradually falling into the corresponding conveying troughs. Meanwhile, the installation of primary guardrail 1, secondary guardrail 5, and tertiary guardrail can effectively prevent vegetables from falling out of the device.

[0031] In a further embodiment, the diameter of the primary conveying trough 3 is larger than the diameter of the secondary conveying trough 7, and the diameter of the secondary conveying trough 7 is larger than the diameter of the tertiary conveying trough. This allows for better guidance of the initially disordered vegetables through a gradual decrease in diameter from top to bottom, facilitating subsequent identification and sorting.

[0032] As attached Figure 3 As shown, in another specific embodiment, the identification and sorting structure includes a sorting plate, a camera bracket 11, a camera 12, and a cylinder 24. The sorting plate is installed on the frame 14 of the sorting equipment. Several sorting conveyor troughs 10 are provided at the upper end of the sorting plate. One end of the sorting conveyor trough 10 is connected to the conveyor plate on the same layer, and the other end of the sorting conveyor trough 10 is connected to the good product conveying structure. A camera 12 for observing the vegetables on the sorting plate is installed above the sorting plate through the camera bracket 11. A cylinder 24 is provided on one side of the sorting conveyor trough 10 located below the camera 12, and a defective product discharge port 23 is opened on the other side. The defective product conveying structure is set below the defective product discharge port 23. The cylinder 24 is used to push the vegetables in the sorting conveyor trough 10 to the defective product discharge port 23. The cylinder 24 is electrically connected to the camera 12. Therefore, during use, the camera 12 can monitor the vegetables on the sorting conveyor 10 below it, and when a defective vegetable is detected, a signal is sent to the cylinder 24, which then pushes the vegetable to the defective product discharge port 23. In this embodiment, the section of the sorting conveyor 10 equipped with the cylinder 24 and the defective product discharge port 23 is not equipped with a baffle.

[0033] In this embodiment, the three-stage conveyor plate and the sorting plate can also be integrated into one unit. The sorting plate is hinged to the end of the lower stage on the side closer to the lower stage, and the three-stage conveying groove of the three-stage conveyor plate and the sorting conveying groove 10 of the sorting plate are connected.

[0034] In a further embodiment, a sorting conveyor baffle 9 is provided between the sorting conveyor troughs 10 on the sorting plate, and in the portion located between the camera bracket 11 and the conveyor plate on the same layer. The diameter of the sorting conveyor troughs 10 is larger than the diameter of the conveyor troughs on the same layer of the conveyor plate. This allows the sorting conveyor baffle 9 to effectively guide the vegetables to be identified and sorted, while the wider diameter allows for a fuller view of the vegetables to the camera 12, increasing sorting accuracy.

[0035] In a further embodiment, the good product conveying structure includes a conveyor pipe connection structure 22, a good product conveying pipe 18, and a good product storage area 13. The end of the sorting conveyor trough 10 is provided with the conveyor pipe connection structure 22, which connects to one end of the good product conveying pipe 18. The other end of the good product conveying pipe 18 is connected to the good product storage area 13, which is located on the side of the lowest first layer 26 of the sorting equipment frame 14. Thus, when vegetables pass the inspection, they are directly input into the good product storage area 13 for storage via the sorting conveyor trough 10 and the good product conveying pipe 18. In this embodiment, the good product conveying pipe 18 can be a main pipe with several branch pipe joints, or several good product conveying pipes 18 can be used together.

[0036] In a further embodiment, the defective product conveying structure includes a defective product conveyor belt 15, a conveyor belt drive device 17, and a defective product collection point 16. The defective product conveyor belt 15 is located on the lowest first layer 26 of the sorting equipment frame 14. One end of the defective product conveyor belt 15 is positioned below the defective product discharge port 23, and the other end of the defective product conveyor belt 15 is provided with the defective product collection point 16 for receiving defective products. The conveyor belt drive device 17 is used to drive the defective product conveyor belt 15 to move. In this way, the received substandard vegetables can be uniformly transported to the defective product collection point 16 via the defective product conveyor belt 15.

[0037] In another specific embodiment, a waste collection point 25 is also included. The layers of the sorting equipment frame 14 equipped with the vibrating conveyor structure are all hollow structures. The waste collection point 25 is located below the hollow structure and is used to receive debris falling from the filter holes and the hollow structure. In this embodiment, the vibrating motor is mounted via a bracket. This allows for convenient collection and processing of falling impurities.

[0038] Among them, the good product storage area 13 is used to temporarily store good quality vegetables, the defective product storage area 16 is used to temporarily store defective vegetables, and the garbage storage area 25 is used to temporarily store sand and other impurities.

[0039] In use, this invention transports vegetables to a primary conveyor plate, which is vibrated by a primary vibration motor 21, placing the vegetables into individual primary conveyor troughs 3 and separating them with primary conveyor baffles 4. During vibration, impurities attached to the vegetables fall into the waste collection 25 through the primary filter holes 2. The secondary conveyor trough 7 is narrower than the primary conveyor trough 3, and the vegetables in the secondary conveyor trough 7 are conveyed downwards sequentially. The vegetables are then transported by a tertiary conveyor plate to the sorting conveyor trough 10 of the identification and sorting structure, where they are identified by a camera 10 to determine whether the vegetables are susceptible to pests or contamination. For vegetables identified as defective, the camera 10 controls a cylinder 24 to discharge them into the defective product discharge port 23, where they fall onto the defective product conveyor belt 15 and flow into the defective product collection area 16. For vegetables identified as good, they flow into the good product collection area 13 through the good product conveyor pipe 18.

[0040] Specifically, before the camera 10 is used, a comparison library is trained using existing technology to identify substandard vegetables with strange shapes, partial discoloration, overall discoloration, or pests. In actual operation, the camera 10 will take a picture of the current vegetable and match it with the substandard vegetables in the comparison library. If the match is successful, it is a substandard product; otherwise, it is a good product.

[0041] Specifically, cylinder 24 can be composed of a bottom cylinder and a piston. After cylinder 24 receives an extension signal, the bottom cylinder supplies air to make the piston move outward. After cylinder 24 receives a contraction signal, the bottom cylinder releases air to make the piston move inward. When camera 10 identifies vegetables as defective, there is no baffle in the middle of the rear half of the sorting conveyor trough 10. Cylinder 24 will then extend to push the defective vegetables out of the sorting conveyor trough 10 and into the defective discharge port 23. Then cylinder 24 will retract back to its original position. When camera 10 identifies vegetables as good, cylinder 24 will not move. Good vegetables will flow along the sorting conveyor trough 10, through the good product conveyor pipe 18, into the good product storage area.

[0042] This invention uses camera 10 to determine whether vegetables are good or bad, and can process a large number of vegetables in a short time. Compared with manual sorting, it is faster and more stable. During the sorting process, it can remove impurities attached to the surface of vegetables. It can also quickly adjust the sorting objects according to different market demands and the characteristics of vegetable varieties.
