Vibration classifier for processing larimichthys crocea and classifying method of vibration classifier

Abstract

The invention relates to a vibration classifier for processing larimichthys crocea. The vibration classifier comprises an eccentric wheel mechanical vibration device, a barrel-shaped material receiver, fish body classifying tank bodies for distinguishing small-size fish bodies from medium-size fish bodies and large-size fish bodies, and discharging conveyors corresponding to the fish body classifying tank bodies for distinguishing small-scale fish bodies from medium-scale fish bodies and large-scale fish bodies. An orientating and classifying long tank body is sequentially provided with a fish body head-tail orientating segment tank body, a fish body turning side-standing declining chute segment tank body, a fish body side-erecting sliding segment U-shaped tank body, a small-size fish body classifying segment tank body, a medium-size fish body classifying segment tank body and a large-size fish body classifying segment tank body. The barrel-shaped material receiver and the front end of the orientating and classifying long tank body are in gap connection. After raw material fish are fed into the barrel-shaped material receiver, under the combined action of a rotating material plate and a vibrating device, the raw material fish slides into the orientating and classifying long tank body, the situations that fish bodies lie sideways and go forwards in a manner that fish heads are at the front part and fish tails are at the rear part, the fish bodies turn, side-stand and slide, and the fish bodies do not overlap, step, side-stand and go forwards are sequentially realized, and when the fish bodies in array pass through the small-size fish body classifying tank body, the medium-size fish body classifying tank body and the large-size fish body classifying tank body, the fish bodies separately fall into the below corresponding small fish body discharging conveyor, the medium fish body discharging conveyor and the large fish body discharging conveyor, so that multiple-size classified treatment of the larimichthys crocea in batch is realized.

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
