A sorting and orientation device for prawns

Abstract

The invention discloses a prawn sequencing orientating device. The prawn sequencing orientating device comprises a rack, a sequencing mechanism, a separating mechanism, a rotating mechanism, an orientating mechanism and an image acquisition and control system, wherein the sequencing mechanism is mounted on the rack, and comprises a conveyor belt, a sequencing belt and a sequencing drive mechanism;the conveyor belt and the sequencing belt are separately connected to the sequencing drive mechanism; the sequencing belt is positioned above one side of the conveyor belt, and the sequencing belt and the conveyor belt are arranged in parallel; left and right sequencing blocks are correspondingly arranged on the conveyor belt and the sequencing belt separately; a sequencing channel is formed between the left sequencing block and the right sequencing block; the separating mechanism is mounted on the rack and is positioned at one end of the rack; the tail end of the separating mechanism corresponds to the inlet of the sequencing mechanism; the rotating mechanism is mounted on the rack and is positioned at the other end of the rack; the orientating mechanism is mounted on the rotating mechanism, and corresponds to the outlet of the sequencing mechanism; and the image acquisition and control system corresponds to the orientating mechanism.

Description

technical field [0001] The invention relates to the field of aquatic machinery, in particular to a sorting and orientation device for prawns based on machine vision. Background technique [0002] Shrimp shell is thin and fat, with high meat content, delicious meat and rich nutrition. It is a high-quality food material for cooking a variety of delicacies and making a variety of leisure and flavor foods, and is deeply loved by consumers at home and abroad. Shrimp is one of the most demanded aquatic products in the world. In 2016, the total global shrimp output was about 4 million tons, and the total output of China, India, Thailand, Indonesia, Vietnam and Ecuador exceeded 75% of the global total shrimp output. China is the world's largest shrimp producer and one of the major shrimp trading countries. Shrimp is an important product of rough processing after harvesting of prawns. Among the shrimp products exported by China, the total amount of shrimps accounts for about half. ...

AI Technical Summary

Problems solved by technology

There is no mature and reliable prawn sorting and orientation device in the prior art, and the sorting and orientation of prawns is still done manually

Due to the unique shape and structure of prawns, automatic sorting and orientation is still a technical problem in the process of prawn processing, which restricts the improvement of production efficiency and product quality in the prawn processing industry
