Description

Technical Field

[0001] The utility model belongs to the technical field of vaccine production equipment, and particularly relates to a special egg candling lamp for white eggs used in vaccine production. Background Art

[0002] In the process of vaccine production by using chicken embryo inoculation, an egg candling device is usually used to observe the condition of chicken embryos. Fertilized chicken embryos need certain environmental factors such as temperature and humidity to complete the development process of chicken embryos into chicks. In order to timely understand the development condition of chicken embryos, and timely remove undeveloped chicken embryos or chicken embryos with development problems, to ensure the effectiveness of the subsequent virus harvesting link and improve the quality of virus vaccine products, an egg candling device is usually required.

[0003] The currently used egg candling device is generally an egg candling box, which usually includes a box body with a light source. When in use, a whole tray of chicken embryos is placed on the box body, and the light source irradiates from bottom to top. An operator observing from above can judge the development condition of chicken embryos through the color presented by the chicken embryos. Generally, well-developed chicken embryos can observe clear blood vessels, and even the movement of embryos can be observed. Normally, the placenta part of the chicken embryo is dark and the egg white part is translucent.

[0004] However, the above-mentioned egg candling box has a relatively low inspection efficiency for chicken embryos and cannot realize continuous egg candling operation. In the actual working process, it is necessary for staff to place a whole tray of chicken embryos on the egg candling box, use the egg candling lamp to inspect the chicken embryos, and then remove the whole tray of chicken embryos from the egg candling box. Such frequent operations seriously affect the efficiency. In addition, the egg candling lamp will generate a large amount of heat during long-term operation, but the egg candling lamp in the above-mentioned egg candling box lacks a heat dissipation and cooling function. During use, if the high-temperature egg candling lamp irradiates the chicken embryos at a close distance for a long time, it is easy to scald the chicken embryos and cause losses. Therefore, it is urgent to design a special egg candling lamp for white eggs used in vaccine production to solve the above problems. Content of the Utility Model

[0005] The utility model provides a special egg candling lamp for white eggs used in vaccine production with reasonable structural design to solve the technical problems existing in the known technology. The utility model can perform efficient inspection operations on batches of chicken embryos, with convenient operation and low labor intensity. At the same time, the egg candling lamp can be dissipated heat and cooled during the inspection process to avoid high-temperature damage to chicken embryos.

[0006] The technical solution adopted by the present utility model to solve the technical problems existing in the known technology is as follows: A special egg candling lamp for white eggs used in vaccine production includes a frame. An egg candling lamp device is installed on the frame. A cold air intake hood communicating with its inner cavity is installed on the egg candling lamp device. A heat dissipation and cooling device is arranged in the cold air intake hood for blowing cold air into the egg candling lamp device. It also includes a transverse movement device installed on the frame for driving the egg candling lamp device to move horizontally. It further includes an adjustment device installed on the transverse movement device for driving the egg candling lamp device to swing up and down. It also includes an egg tray conveying structure installed on the frame. Above the transmission surface of the egg tray conveying structure, two groups of egg tray limiting members are arranged oppositely. The transverse movement direction of the egg candling lamp device is perpendicular to the transmission direction of the egg tray conveying structure. The egg candling lamp device includes a lamp box provided with a plurality of ventilation holes and connected to the cold air intake hood. An illumination mounting frame is installed in the lamp box. A plurality of groups of lighting lamp components arranged in parallel and electrically connected to a power source are installed on the illumination mounting frame. Notches corresponding to the plurality of groups of lighting lamp components are respectively opened at the bottom of the lamp box. A corrugated cover is installed at each notch.

[0007] The advantages and positive effects of the present utility model are as follows: The present utility model provides a special egg candling lamp for white eggs used in vaccine production. By setting the egg tray conveying structure and the egg tray limiting members, the chicken embryo tray can be conveyed forward to facilitate the candling inspection of the whole tray of chicken embryos, and the whole tray of chicken embryos can be transferred out of the inspection area after the inspection is completed. By setting the egg candling lamp device, an inspection irradiation source can be provided for the row of chicken embryos. By setting the cold air intake hood and the heat dissipation and cooling device, cold air can be blown into the inner cavity of the egg candling lamp device, thereby cooling and dissipating heat for each lighting lamp component in the egg candling lamp device, avoiding losses caused by the heat generated by the long-term operation of the lighting lamp components scalding the chicken embryos to death. By setting the corrugated cover, it can play a buffering role when the egg candling lamp device contacts the chicken embryos, avoiding breaking the chicken embryos, and also playing a spacer role during the inspection process to further achieve the purpose of preventing scalding. By setting the transverse movement device, the egg candling lamp device can be driven to move horizontally. By setting the adjustment device, the egg candling lamp device can be driven to swing up and down. Therefore, the transverse movement device and the adjustment device work together to drive the egg candling lamp device to move and swing repeatedly, and then the whole tray of chicken embryos can be candled and inspected row by row in turn. The present utility model can perform efficient inspection operations on a batch of chicken embryos, with convenient operation and low labor intensity. At the same time, the egg candling lamp can be cooled and dissipated heat during the inspection process to avoid high-temperature damage to the chicken embryos.
