Hatching egg detector and hatching egg screening method

Abstract

The invention discloses a hatching egg detector, which comprises a detection device, a tray and a separation lifting cylinder. The hatching egg detector is characterized in that the detection device comprises a plurality of detection heads and a processor. The detection heads are capable of emitting the light onto hatching eggs on the tray, detecting the light reflected by the hearts of the hatching eggs and then transmitting the detected information to the processor. The separation lifting cylinder is connected with the tray and is used for controlling the tray to move up and down. The entire detecting process is conducted based on the light reflection principle to detect the egg heart rate of hatching eggs. However, the light reflection effect is not affected by the ages of hatching eggs in days. The heart rate detection heads of the detection device are in direction contact with hatching eggs, while the contact parts thereof are accommodated in an inner space of the detection heads. A light emitting and receiving annunciator is arranged inside the inner space of the detection heads, so that the detection result of hatching eggs is not influenced by the external light. After the detection process, the detection result is transmitted to a negative pressure device by the processor. Therefore, hatching eggs can be automatically screened under the driving effect of the cylinder.

Description

technical field [0001] The invention relates to the field of egg detection and screening, in particular to an egg detector and a method for screening eggs. Background technique [0002] At present, domestic hatcheries mainly use hand-held egg cankers to illuminate the eggs in the hatching trays to identify the embryonic development. The hand-held egg canisters are equipped with halogen lamps. In a relatively dark space, the halogen lamps are pointed at The big head of poultry eggs is irradiated at zero distance. According to the developmental characteristics and experience of different stages of poultry egg embryo development, the quality and speed of poultry egg embryo development are judged, and then the problematic ones are manually removed, and then the live embryos are transferred to the designated position. This method Detection and screening are slow. In addition, Chinese Invention Patent No. 200580034368.9 and Chinese Invention Patent No. 201210393382.X disclose equ...

Problems solved by technology

[0003] However, as far as the existing technology is concerned, it is only possible to identify the heart rate of eggs with a younger age. When the eggs are relatively older, due to the poor light transmission inside the eggs, it is impossible to detect the heart rate of older eggs through light-transmitting detection methods. for heart rate monitoring
