Egg candling method and device in egg incubation

Abstract

The invention discloses a method and a device for illuminating poultry eggs during hatching. Put the hatched eggs into the egg candling device, and shine the light source directly on the big end of the egg in a dark environment. The small end of the egg uses a photoresistor to receive the amount of light transmitted. The more light transmitted, the resistance of the photoresistor The smaller it is, when the resistance value of the photoresistor does not reach a certain threshold value, the circuit connected to the photoresistor is turned on, so that it is judged that the poultry eggs cannot be hatched. The egg candling device is a flip-top black body box, including a flip cover, a light source board, a main box body, a photosensitive plate and a corresponding switch detection circuit. The flip cover is connected to one end of the main box, the light source board and the switch circuit are placed in the flip cover, the light source is surrounded by an egg head and a shading curtain, and the hatching tray with poultry eggs, the photosensitive plate and the In the detection circuit, the photosensitive plate is composed of a photoresistor array, and an indicator light is set next to the photoresistor. The invention is mainly used for an egg candling method and device for rejecting unhatchable eggs during poultry egg hatching.

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
