Description

Technical Field

[0001] The invention belongs to the technical field of detection equipment, and in particular relates to an online detection device for corn seed quality. Background Art

[0002] Corn seeds are an important prerequisite for ensuring corn quality and yield, and the important quality indicators of corn seeds include bulk density, imperfect kernels (insect-eaten kernels, diseased kernels, broken kernels, sprouted kernels, moldy kernels and heat-damaged kernels), impurities, color, odor, moisture content and moldy kernels. In addition to external forms such as impurities and color, there are also important internal forms such as imperfect kernels, moisture content and moldy kernels. These problems mainly arise in the harvesting, drying, transportation and storage of corn production. As for the internal form problems of corn seeds, since the seed coat is intact and there is no abnormality in appearance, it is difficult to detect and not easy to attract people's attention under normal circumstances, which seriously affects the germination of seeds, the degree of uniform emergence and the disease resistance of the plants that eventually grow; At present, the detection of corn seed quality mainly adopts morphological, physiological and biochemical and biotechnology (protein electrophoresis and DNA molecular markers, etc.) methods. These methods are subjective and arbitrary, require special reagents, are destructive to samples, have limited detection quantity, are expensive and have high requirements for operators. In recent years, domestic and foreign scholars have done a lot of research on corn seed quality detection, mainly using spectral imaging technology combined with machine learning algorithms to detect internal and external characteristic indicators of seed quality. However, these studies or the devices developed by the research are all based on static conditions, which is difficult to meet the requirements of online rapid detection of the quality of a large number of corn seeds. To solve the above problems, a Chinese patent with publication number CN117647492B discloses a robotic arm-coordinated air-suction corn seed quality online detection device and method. The prior art selects unqualified seeds through a hyperspectral imaging system and a robotic arm. When in use, the robotic arm takes different amounts of time to process the seeds each time, and the spectral imaging system takes pictures and processes them through a computer at a fixed time. As a result, the various work processes of the prior art need to wait for each other, which reduces the processing speed. In addition, the prior art only performs screening once, and the screening effect is limited. Summary of the invention
