Vibration classifier for processing large yellow croaker and its classifying method

Abstract

The invention relates to a vibrating classifier for processing large yellow croaker, comprising an eccentric mechanical vibration device, a cylindrical feeder, a classification tank for classifying small, medium and large fish bodies and a corresponding unloading conveyor; The tank body is sequentially provided with the fish body head and tail directional section tank body, the fish body turning side vertical downward slide section tank body, the fish body side vertical sliding section U-shaped tank body, the small size fish body grading section tank body, and the medium size fish body. Body grading section tank body and large-size fish body grading section tank body; the cylindrical feeder and the front end of the oriented and grading long groove are connected with a gap. Together with the vibration device, it slides into the directional and grading long trough, and in turn realizes the fish head in the front and the tail in the back, the fish body rotates and slides on the side, and the fish body moves on the side without overlapping. When arranging through the small, medium and large size fish grading troughs, they fall into the corresponding small, medium and large fish feeding conveyors below, thereby realizing the multi-specification grading treatment of batches of large yellow croaker.

Description

technical field [0001] The invention relates to a vibrating classifier and a classifying method for the application occasion of processing large yellow croaker, belonging to the technical field of fish processing. Background technique [0002] The fish grader can divide the same fish with different sizes into several grades according to body thickness or weight, which is beneficial to the adaptability requirements of graded sales and mechanized processing, and can improve the quality and production efficiency of processed products. [0003] Fish graders can generally be divided into size graders and weight graders. [0004] Since the body length, weight and body thickness of common fish have a certain proportional relationship, the grading of fish bodies is usually carried out according to the thickness of the fish body. There are three types of common fish size graders: tube type, belt type and drum type. ①Tube classifier: It is mainly composed of a number of circular tub...

AI Technical Summary

Problems solved by technology

[0006] The existing fish size classifiers and fish weight classifiers are basically single-machine operations with disordered mixing, which is very inconvenient for subsequent processing of fish products, especially large yellow croakers; in addition, the classification of existing body classifiers The accuracy and reliability are also insufficient, and the equipment cost of the weight classifier is relatively high
