Method and device for automatically carefully sorting and grading shrimps

Abstract

The invention discloses a device for automatically carefully sorting and grading shrimps. The device comprises a feeding system, a sorting channel, an image collecting system, a grading system and an image processing system; the feeding system is used for outputting to-be-sorted shrimps to the sorting channel in a single row; the sorting channel consists of a buffering channel and a sampling channel which are sequentially connected, the sampling channel is divided into a plurality of single-row channels, the buffering channel is internally provided with a plurality of direction adjusters, and used for separating raw material shrimps, output by the feeding system, into singles, and adjusting the posture of each raw material shrimp entering single-row channel; the image collecting system is used for collecting images of the raw material shrimps; the grading system comprises spray nozzles corresponding to single-row channels, and the spray nozzles are controlled by the image processing system and used for blowing the shrimps to enter different receiving tanks; the image processing system is used for analyzing the images, grading the image of each shrimp, and emitting the signal for controlling the grading system according to the graded results. The invention further discloses a method for automatically carefully sorting and grading shrimps.

Description

technical field [0001] The invention relates to the technical field of aquatic products, in particular to an automatic selection and classification method and device for shrimp. Background technique [0002] As one of the six largest shrimp producing countries in the world, my country sends a large amount of raw shrimp to the international market every year. However, the overall low price of my country's raw shrimp exports, small market share, and insufficient competitiveness are the reasons for the decrease in the export volume of my country's raw shrimp. With the deepening and adjustment of the industrial structure, many shrimp farms have started pond culture one after another. The large-scale breeding base makes the workers busy with the cultivation and breeding of pre-natal shrimp species, but the harvest of post-natal raw shrimp requires a lot of investment. The link of manpower, material resources and financial resources is often neglected, resulting in the death of m...

Problems solved by technology

[0007] The automatic selection and grading device of the present invention is mainly aimed at the problem of impurities such as weeds, small fish, anoxic, and roasted shrimps mixed in the raw shrimps caught ashore during the harvest season of raw shrimps, and also for the purpose of improving the quality of raw shrimps during product processing. To meet the needs of product selection and grading, specially design and develop an automatic selection and grading method for shrimp based on computer vision technology that is suitable for use in raw shrimp farms and processing plants, with a small footprint and a high degree of intensification with device
