Description

Technical Field

[0001] This utility model relates to the field of agricultural product quality inspection technology, and in particular to a conveying device for inspecting the quality of agricultural product processing. Background Technology

[0002] In the field of agricultural product processing and quality control, existing technologies, such as the Chinese utility model patent with authorization announcement number CN220658425U, provide a sorting device for agricultural product testing. This device mainly includes a product conveyor line, an image recognition device, and a sorting mechanism. Agricultural products are conveyed via the product conveyor line. During the conveying process, the image recognition device takes pictures of the surface of the agricultural products from above for identification, and then the sorting mechanism sorts the identified agricultural products.

[0003] However, while this device improves the efficiency of agricultural product testing to some extent, it still has significant limitations. Specifically, because image recognition equipment can only photograph agricultural products from above, problems such as rot, insect damage, or other quality issues at the bottom of the product often go undetected. This blind spot not only affects the accuracy of agricultural product testing but may also allow substandard products to enter subsequent processing stages, posing a potential threat to product quality and consumer health.

[0004] To overcome this deficiency in existing technology, this utility model proposes a conveying device for quality inspection of agricultural products. By introducing dual-camera imaging technology, this device achieves comprehensive inspection of both the upper and lower surfaces of agricultural products, thereby greatly improving the accuracy and reliability of the inspection. Simultaneously, combined with an intelligent transfer mechanism and a highly efficient sorting system, this device enables automated conveying, inspection, and sorting of agricultural products, further improving the efficiency and quality of agricultural product processing.

[0022] The following is in conjunction with the appendix Figure 1-3 The specific embodiments of this utility model will be described in further detail.

[0023] Please refer to the attached image. Figure 1-3This utility model discloses a conveying device for quality inspection of processed agricultural products, including a product conveying line 1, an image recognition system 2, and a transfer mechanism 3 disposed between the product conveying line 1 and the image recognition system 2. The product conveying line 1 is used to convey agricultural products such as potatoes, tomatoes, cucumbers, and cabbages. The image recognition system 2 is used to photograph the agricultural products and judge their quality through image recognition technology. The transfer mechanism 3 is used to transfer the agricultural products between the product conveying line 1 and the image recognition system 2.

[0024] The image recognition system 2 includes a device bracket 21, an acrylic transparent plate 22 fixed on the device bracket 21, an upper camera 23 and a lower camera 24 fixed to the device bracket 21 and located above and below the acrylic transparent plate 22 respectively, and a controller 25 fixed on the device bracket 21 and electrically connected to the upper camera 23 and the lower camera 24. Agricultural products are conveyed on the product conveying line 1 and transferred to the surface of the acrylic transparent plate 22 by the transfer mechanism 3. Since the acrylic transparent plate 22 is made of transparent material, the upper and lower parts of the agricultural products can be photographed by the upper camera 23 and the lower camera 24 respectively. This allows for the acquisition of image data of both the upper and lower parts of the agricultural products, making the quality inspection of agricultural products more accurate and avoiding the problem of inaccurate inspection caused by only photographing the agricultural products from the top in the prior art.

[0025] Specifically, the product conveyor line 1 includes a first conveyor 11 located on the left side of the equipment support 21 and a second conveyor 12 located on the right side of the equipment support 21. The second conveyor 12 is connected to a sorting mechanism 13. The first conveyor 11 is used to move agricultural products to the left side of the equipment support 21. The agricultural products are transferred to the surface of the acrylic transparent plate 22 for inspection by the transfer mechanism 3. After inspection, the agricultural products are transferred to the surface of the second conveyor 12 by the transfer mechanism 3. At the same time, the controller 25 analyzes the images captured by the upper camera 23 and the lower camera 24. If the quality of the agricultural products is qualified, the agricultural products are sent to the next workstation through the second conveyor 12. If the quality of the agricultural products is unqualified, the agricultural products are sorted out separately from the second conveyor 12 by the sorting mechanism 13.

[0026] In some embodiments, the transfer mechanism 3 includes a first pusher plate 31 movably disposed on the surface of the first conveyor 11 for pushing agricultural products onto the surface of the acrylic transparent plate 22, a second pusher plate 32 movably disposed on the surface of the acrylic transparent plate 22 for pushing agricultural products onto the surface of the second conveyor 12, and a drive mechanism 33 connected to the equipment bracket 21 for driving the first pusher plate 31 and the second pusher plate 32 to move.

[0027] In order to enable the upper camera 23 and the lower camera 24 to capture clear images, LED lights 4 are fixedly installed on the equipment bracket 21 above and below the acrylic transparent plate 22. The LED lights 4 can illuminate the agricultural products from the bottom and top, thereby making the images captured by the upper camera 23 and the lower camera 24 clearer.

[0028] In some embodiments, the sorting mechanism 13 includes a telescopic cylinder 131 fixed on the second conveyor 12 and a sorting pusher plate 132 fixedly connected to the telescopic cylinder 131. When the telescopic cylinder 131 extends and retracts, it drives the sorting pusher plate 132 to move in the width direction of the second conveyor 12. When the image recognition system 2 detects that the agricultural product has a quality problem, the controller 25 will send a command to the telescopic cylinder 131 to extend the telescopic cylinder 131 and push the agricultural product away from the side of the second conveyor 12.

[0029] Furthermore, a first infrared sensor 5 is installed at the end of the first conveyor 11 near the equipment support 21, and a second infrared sensor 6 is installed on the second conveyor 12 at the position of the sorting mechanism 13. The first infrared sensor 5 and the second infrared sensor 6 are used to detect the position of agricultural products. It can be understood that in order to ensure the orderly progress of the inspection work, agricultural products need to be transported through the first conveyor 11 in an orderly manner. With the setting of the first infrared sensor 5, when the agricultural products are transported through the first conveyor 11 and reach the loading station on the left side of the equipment support 21, the first infrared sensor 5 can detect the position of the agricultural products, causing the first conveyor 11 to automatically stop rolling. In addition, with the setting of the second infrared sensor 6, when the image recognition system 2 identifies agricultural products with quality problems, the image recognition system 2 will send an instruction to the sorting mechanism 13 in advance. When the second infrared sensor 6 detects that the agricultural products with quality problems have reached the designated position, it will feed back to the controller 25. The controller 15 will send an instruction to the telescopic cylinder 131 to automatically push away the unqualified agricultural products.

[0030] In some embodiments, the second conveyor 12 is fixedly equipped with a non-conforming product hopper 14 at the position of the sorting mechanism 13. A collection basket can be placed directly below the non-conforming product hopper 14 to collect agricultural products with quality problems. Alternatively, another set of conveying mechanisms can be installed to send non-conforming agricultural products to a designated location.

[0031] Specifically, the first push plate 31 and the second push plate 32 are vertically arranged and their upper ends are fixedly connected by a connecting plate 34. The driving mechanism 33 includes a longitudinal moving mechanism 331, a transverse moving mechanism 332, and a mounting plate 333. The connecting plate 34 is horizontally movably mounted on the surface of the mounting plate 333. The transverse moving mechanism 332 is connected to the mounting plate 333 to push the connecting plate 34 to move horizontally. The longitudinal moving mechanism 331 is connected to the product conveying line 1 to drive the mounting plate 333 to move up and down. In use, agricultural products are placed on the surface of the acrylic transparent plate 22 for photographic inspection, and the left side of the acrylic transparent plate 22 is connected to the first conveying line 333. When the feeding mechanism 11 is replenished and the inspection is completed, the longitudinal moving mechanism 331 drives the mounting plate 333 to move downward, and then the lateral moving mechanism 332 drives the connecting plate 34 to move to the right, thereby driving the first push plate 31 and the second push plate 32 to move to the right. The agricultural products on the surface of the first conveying mechanism 11 are pushed to the surface of the acrylic transparent plate 22 by the first push plate 31, and the agricultural products on the surface of the acrylic transparent plate 22 are pushed to the surface of the second conveyor 12 by the second push plate 32. Then the longitudinal moving mechanism 331 drives the mounting plate 333 to move upward, and the lateral moving mechanism 332 drives the connecting plate 34 to move to the left and return to its original position.

[0032] In some embodiments, the longitudinal movement mechanism 331 is a telescopic cylinder structure.

[0033] In some embodiments, the lateral movement mechanism 332 includes a servo motor 3321 fixed to the surface of the connecting plate 34, a gear 3322 fixed to the output shaft of the servo motor 3321, and a toothed plate 3323 fixed to the mounting plate 333. The gear 3322 and the toothed plate 3323 are meshed together. In use, when the external power supply of the servo motor 3321 is turned on, the output shaft of the servo motor 3321 drives the gear 3322 to rotate. When the gear 3322 rotates, it moves in the length direction of the toothed plate 3323, thereby driving the servo motor 3321 to move. The movement of the connecting plate 34 is realized by the movement of the servo motor 3321.

[0034] This utility model discloses a conveying device for quality inspection of processed agricultural products. Through the coordinated operation of a product conveying line 1, an image recognition system 2, and a transfer mechanism 3, it achieves comprehensive photographing and inspection of agricultural products. The image recognition system 2 utilizes dual cameras to capture images of the upper and lower parts of the agricultural products, improving inspection accuracy. The transfer mechanism 3, through the cooperation of a first push plate 31, a second push plate 32, and a drive mechanism 33, automatically transfers agricultural products between the product conveying line 1 and the inspection platform. When unqualified agricultural products are detected, the sorting mechanism 13 automatically sorts them from the product conveying line 1 to the unqualified product unloading hopper 14. This ensures efficient and accurate processing of agricultural products.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
