Description

Technical Field

[0001] This utility model relates to the field of egg screening technology, specifically to a non-destructive testing and screening device for fertilized eggs. Background Technology

[0002] Currently, domestic poultry farms are required to achieve a hatching rate of over 90% for hen eggs. However, in actual production, many farms fail to meet this standard. Removing infertile eggs early in the incubation process would increase the hatching rate, potentially increasing my country's annual hen egg production by hundreds of millions of eggs. The identified infertile eggs could then be consumed by consumers, reducing waste and conserving resources. Current hen egg testing mostly relies on manual candling in the later stages of incubation, which is labor-intensive, inefficient, and increases the risk of egg damage.

[0003] Chinese Patent CN206848182U discloses a device for identifying brown-shelled infertile and fertilized eggs based on machine vision technology. The device includes an egg tray, a computer, an industrial camera, a transmission mechanism, a light source mechanism, and a grading robotic arm. The egg tray is friction-fitted with a transmission belt on the transmission mechanism. The industrial camera is fixed above the transmission mechanism via a support rod and connected to one side of the transmission mechanism. The industrial camera is connected to the computer. The light source mechanism is placed on the ground, positioned directly below the transmission mechanism, corresponding to the industrial camera. The grading robotic arm is installed on one side of the tail end of the transmission mechanism. This invention, a device for identifying brown-shelled infertile and fertilized eggs based on machine vision technology, utilizes machine vision to acquire images of hatching eggs. After image preprocessing, a model for identifying infertile and fertilized eggs is established, enabling automated, non-destructive testing of brown-shelled hatching eggs and facilitating identification of brown-shelled eggs in the early stages of incubation.

[0004] However, the above technical solution has the following shortcomings: the equipment is not only complex in structure and has high manufacturing costs, but also has poor continuity in detection, making it impossible to achieve automated detection of fertilized eggs. The detection efficiency is low and it cannot meet the needs of large-scale detection in farms. Utility Model Content
