Egg candling method and device in poultry egg hatching

Abstract

The invention discloses an egg candling method and device in egg incubation. The method comprises the steps that incubated eggs are put into an egg candling device; a light source directly irradiates large ends of the eggs in dark environment; the small ends of the eggs receive light transmission amount through a light dependent resistor; the more is the light transmission amount, the smaller the resistance value of the light dependent resistor is; when the resistance value of the light dependent resistor does not reach a certain threshold value, a circuit connected with the light dependent resistor is connected, so that the fact that the eggs cannot be incubated is judged. The egg candling device adopts a black body box with a flip, and comprises the flip, a light source plate, a main box body, a sensitive plate and a corresponding switching detection circuit. The flip is connected with one end of the main box body; the light source plate and a switching circuit are arranged in the flip; an egg candling head and a shading curtain are arranged on the periphery of the light source; a hatching tray containing the eggs, the sensitive plate and a detection circuit are arranged in the main box body from the upper part to the lower part in sequence; the sensitive plate comprises light dependent resistor arrays; an indicating lamp is arranged beside the light dependent resistor. The egg candling method and device are mainly used for remove eggs which cannot be incubated in egg incubation.

Description

technical field [0001] The invention relates to hatching of poultry eggs, in particular to a method and device for judging whether poultry eggs can hatch during the hatching process. Background technique [0002] At present, the domestic judgment of poultry egg hatching ability mainly relies on manual candling. There are two types of canisters: hand-held canisters and box-type canisters. When canning eggs, it is necessary to manually identify the eggs one by one, which is time-consuming and laborious. There are also some egg-candidating devices that are not matched with the hatching device, and the operation is inconvenient, which prolongs the egg-candidating process and affects the hatching ability of poultry eggs. Contents of the invention [0003] In order to overcome the deficiencies in the above-mentioned existing technology and solve the technical problem of quickly screening out eggs that cannot be hatched during the hatching of poultry eggs, the purpose of the pres...

Problems solved by technology

[0003] In order to overcome the deficiencies in the above-mentioned existing technology and solve the technical problem of quickly screening out eggs that cannot be hatched during the hatching of poultry eggs, the purpose of the present invention is to provide a method and device for candling eggs in poultry egg hatching. After 6-7 days of incubation, take it out and put it into the egg candling device. In a dark environment, shine the spotlight of the light source directly on the big end of the egg. The small end of the egg receives the spotlight with a photoresistor after passing through the egg. The light transmission amount, the change of the light transmission amount guides the change of the resistance value of the photoresistor, and when the resistance value of the photoresistor reaches a certain threshold, it can be judged whether the egg can be hatched
