Problems solved by technology

However, manual candling is a lot of labor and low efficiency, especially when a large number of eggs are hatched at the same time, the manual detection efficiency is far from enough, and after a period of time, due to visual fatigue and other factors, the detection accuracy will decline, and long-term candling work It also affects the vision of the human eye
Therefore, manual inspection can no longer meet the needs of modern production and the employment policy of enterprises

Embodiment 1

[0047] In Example 1, a total of 227 "Meiling" broiler eggs were tested for light transmission on the 0-12th day of incubation, and the eggs came from the same hatchery and the same batch.

[0048] Each light source used in this experiment is a warm white LED with a color temperature of 2700K, a power of 1.35W, and a light sensor of OPT3001. After the eggs are cleaned and disinfected, they are put into the incubator for incubation. On the 0-12th day of incubation, take out the eggs regularly every day and use the above equipment to measure the light transmittance after the light passes through the eggs. On the seventh day, artificially illuminate the eggs to determine the live embryo eggs and record them, and take out the live embryos on the 10th day The eggs were placed in a refrigerator at 2°C for 12 hours, thereby artificially producing 90 eggs with dead embryos and remaining 77 eggs with live embryos. After the measurement on the 12th day, the hatching eggs were inspected. C...

Embodiment 2

[0068] Step 1, the egg tray 47 with the eggs on the egg delivery frame 1 enters the detection device 4, when the egg tray is detected by the egg tray sensor 46, the chain 2 stops running, and the cylinder 42 in the detection device 4 starts to drive The fixed plate 45 and the light amount detection device 5 on it descend, and when the inner edge of the lower end of the light-shielding cap (53) contacts the eggs, the cylinder (42) stops running;

[0069] Step 2, the LED light bead 49 in the detection device 4 is energized, and the LED light bead 49 emits a light beam upwards to pass through the through hole of the egg tray 47 to irradiate the eggs, and the light quantity detection device 5 continuously collects and obtains the light transmittance within 10 seconds. light signal strength;

Abstract

The invention discloses a device and a method for non-destructive identification of a breeding egg. The device comprises breeding egg transporting supports, and chains arranged on the breeding egg transporting supports and used for placing and transporting an egg tray, wherein a detection device used for detecting the development condition of the breeding egg is arranged on the egg transporting supports; the egg tray is driven to horizontally move by the chains and passes through the detection device which is provided with an inlet and an outlet for entry and exit of the egg tray; the positions of the inlet and the outlet are respectively provided with a blackout curtain; and light of an LED lamp bead penetrates through the breeding egg and is received by a light quantity detection deviceto be transmitted to a processor for analysis, so the breeding egg is identified to be a live-embryo egg, an infertile egg or a dead-embryo egg. The device provided by the invention realizes automaticand non-destructive egg irradiation and breeding egg type identification, and has high detection accuracy and efficiency.

Description

technical field [0001] The invention relates to agricultural automation machinery, in particular to a non-destructive identification device and method for breeding eggs. Background technique [0002] Eggs need to be illuminated during the hatching period to determine the development of the eggs. At present, the hatchery detects eggs basically relying on the manual use of hand-held egg lighters to judge the development of eggs. However, manual candling is labor-intensive and inefficient, especially when a large number of eggs are hatched at the same time, the manual detection efficiency is far from enough, and after a period of time, the detection accuracy decreases due to factors such as visual fatigue. Long-term candling work It can also affect the vision of the human eye. Therefore, manual inspection can no longer meet the needs of modern production and the employment policy of enterprises. Contents of the invention [0003] Based on the above background, the present ...
