Description

Technical Field

[0001] The invention relates to the technical field of automatic sorting, and in particular to an automated device capable of sorting mud clams. Background Art

[0002] Mud clams are loved by diners because of their delicious meat and high nutritional value. They are cultivated on a large scale in Zhejiang, Guangdong, Fujian and other places. The surface of the mud clams caught from the breeding ponds is covered with silt and the sizes are different. Therefore, they need to be cleaned and sorted according to their size. In the prior art, there are no mechanical tools and equipment that can realize automatic sorting of mud clams. Therefore, they are currently sorted manually. The manual sorting method is not only labor-intensive, inefficient, and costly, but also may cause obvious size differences among the same level of mud clams after sorting due to the attitude problems of the workers, affecting the product reputation.

[0003] Chinese patent document CN 103426164 A discloses a scallop size calculation method and scallop sorting system based on Opencv image analysis. The two most obvious convex defects of scallops are analyzed by video, and then the midline of the scallop is determined. The size of the scallop is determined based on the midline, and the automatic sorting of scallops is realized. However, there is a big difference in appearance between mud clams and scallops. Therefore, the algorithm in patent document CN 103426164 A cannot be used to identify mud clams. In addition, in this document, scallops need to be analyzed one by one, which has low work efficiency. The technical route of machine vision plus software algorithm is difficult to achieve batch automatic and rapid sorting.

[0004] Compared with clams and scallops, the appearance of mud clams is fuller and the individual shape is nearly oval. Based on the appearance characteristics of mud clams, if a sorting device that can pick up mud clams according to size can be designed, it will surely greatly reduce the labor intensity and labor costs, improve work efficiency, and at the same time, it will not be affected by human attitude and effectively improve the sorting quality.
