Automatic detecting and separating device for eggs with broken shells

Abstract

The invention relates to an automatic detecting and separating device for eggs with broken shells. In an intermittent inlet device, a valve 3 drives a ball 11 by a curvy-edge disc 9 and intermittently allows eggs to enter a collision acoustic generator. The collision acoustic generator comprises stepped plates 20, collision openings 18 and collision blocks formed by upper and lower collision plates which are symmetrically arranged, the eggs roll on the stepped plates 20 in an accelerating manner, and after falling off from steps 17, the eggs collide with the collision plates and generate sound. A pickup recognizer carries out pickup by a pickup K. Induction coils L, tuning capacitors C and resistors R form frequency resonance loops LCR. Resonant signals are amplified by low-frequency amplifiers M according to classes and pass rectifying filters N. Four Or gate circuits of eggs with broken shells and eggs with good shells are separately formed. When T-position electric potential in a bridge is higher than F-position electric potential, a green LED lamp 2 turns bright and indicates that the eggs are eggs with good shells, and when the F-position electric potential in the bridge is higher than the T-position electric potential, a red LED lamp 2 turns bright and indicates that the eggs are eggs with broken shells. A counter G, a solid relay SSR, an electromagnetic relay S and a valve 19 work. The detecting and separating accuracy of the device reaches 100%.

Description

technical field [0001] The invention belongs to agricultural by-product processing machinery, and in particular relates to an automatic detection and separation device for shell-damaged eggs. Background technique [0002] Poultry eggs are rich in protein, fat, multivitamins and trace elements, and are important animal foods in people's daily life. Because poultry egg shells are thin and fragile, once damaged, bacteria will quickly invade and multiply, causing poultry eggs to rot and deteriorate, polluting the environment and bringing disaster to other poultry eggs. One of the important links in processing. At present, domestic and foreign mainly rely on manual detection methods such as eyes or ears to identify and remove damaged poultry eggs, which is not only labor-intensive and production efficiency is low, but also the detection accuracy is affected by workers' attention, physical strength, experience and work attitude. There is no fundamental guarantee, and the detecti...

AI Technical Summary

Problems solved by technology

For acoustic technology, there is a big difference in the quality of poultry eggshells, and the thickness and size of the eggshells are different, which leads to a big difference in the frequency signals obtained by knocking the eggshells, resulting in a decrease in the accuracy of system recognition

At the same time, for the acoustic technology with high environmental requirements, the frequency of the impact signal will incorporate some environmental noise, which will interfere with the identification system
