Equipment and method for identifying living embryos of hatching eggs through photoacoustic coupling

Abstract

The invention discloses equipment and a method for identifying living embryos of hatching eggs through photoacoustic coupling. The equipment comprises a hatching egg conveying device and a hatching egg detection device; the hatching egg detection device is arranged on the hatching egg conveying device; the hatching egg detection device comprises a detection dark box, excitation detection devices,a fixed plate, an air cylinder and a lamp panel; an egg disk with the living embryos is conveyed by the hatching egg conveying device and is subjected to nondestructive detection through the hatchingegg detection device; the air cylinder is arranged at the internal top of the detection dark box; the top end of the fixed plate is connected with the inner top surface of the detection dark box through the air cylinder; the lamp panel is arranged at the inner bottom of the detection dark box; a detection channel is formed between the fixed plate and the lamp panel; and a plurality of excitation detection devices are arranged on the fixed plate. The equipment for identifying existence of the living embryos can automatically identify whether living embryos exist in the hatching eggs, and has high detection precision and high efficiency.

Description

technical field [0001] The invention relates to agricultural automation machinery, in particular to a device and method for identifying live embryos of breeding eggs through photoacoustic coupling. Background technique [0002] Since the fertilization rate and embryo survival rate of the eggs are not 100%, it is necessary to illuminate the eggs during the hatching period to detect the embryos in the eggs. At present, hatcheries mainly rely on manual use of hand-held egg canisters for egg detection. However, the hatchery has a large amount of hatching eggs, especially when a large number of eggs are hatched at the same time, the disadvantage of low efficiency of manual candling is particularly obvious, and the labor workload of the workers is large. Long-term candidature work leads to a decline in detection accuracy and poor vision of the human eye. Can be negatively affected in a working environment where eggs can be found. Some of the existing candid egg products, documen...

However, the hatchery has a large amount of hatching eggs, especially when a large number of eggs are hatched at the same time, the disadvantage of low efficiency of manual candling is particularly obvious, and the labor workload of the workers is large. Long-term candidature work leads to a decline in detection accuracy and poor vision of the human eye. Will be negatively affected by working in an egg care environment

Some of the existing candid egg products, documents and patents mainly focus on the detection of spermless eggs and dead embryonated eggs in the early stage of hatching, and there are few relevant materials in the middle and late stages of hatching. Detection equipment and method for dead embryonated eggs and live embryonated eggs
