Description

Technical Field

[0001] The present invention relates to the technical field of seed vigor detection, and in particular to a seed vigor detection device based on dynamic spectrum integral optimization. Background Art

[0002] While spectroscopy technology enables non-destructive testing of seed viability, traditional methods face significant technical bottlenecks: when seeds are in high-speed motion, insufficient spectral integration time leads to a decrease in signal-to-noise ratio. To ensure accurate detection, existing technologies often require pausing seed motion to complete spectral acquisition. This interrupts the continuous testing process for batches of seeds, significantly reducing overall testing efficiency and making it difficult to adapt to the industry's demand for rapid, large-scale seed quality screening.

[0003] Based on the above technical problems, technical personnel in this field urgently need to develop a seed vitality detection device based on dynamic spectral integration optimization that can effectively solve the technical problem that traditional methods are difficult to achieve stable spectral integration when seeds are moving at high speed, and can complete high-precision detection without forcing seeds to stop.

[0026] A vibration loading module 1 is used to load seeds one by one, so that only one seed remains in the field of view for subsequent inspection; and

[0027] The groove track module 2 is connected to the outlet of the vibration feeding module 1. The groove track module 2 adopts a coating with a low friction coefficient, which can effectively control the uniform speed of seed falling.

[0028] The photoelectric trigger module 3 is arranged at the uppermost end of the groove track module 2, and its function is to realize the synchronization of spectrum acquisition. When the seed falls into the groove track module 2, it will pass through the photoelectric trigger module 3. At this time, the photoelectric trigger module 3 will send a signal to stop the vibration loading module 1 from loading and trigger the spectrum acquisition process to ensure that the spectrum data is collected in time during the seed sliding process. When the seed slides out of the groove track module 2, it will pass through the photoelectric trigger module 3 again. At this time, the photoelectric trigger module 3 will send a signal to inform that the spectrum acquisition is completed, and the vibration loading module 1 can drop the next seed;

[0029] The detection device also includes:

[0030] The spectrum collection and processing mechanism can collect light from the entire seed sliding process and perform spectrometry and detection.

[0031] As a further introduction to this embodiment, the spectrum collection and processing mechanism includes a spectrum collection lens 4, which is arranged directly above the groove track module 2, and the field of view of the spectrum collection lens 4 can completely accommodate the groove track module 2, so as to collect light from the entire sliding process of the seed;

[0032] The spectrum detection module 5 is connected to the spectrum collection lens 4 and is used to split and detect the optical signals of the seeds collected by the spectrum collection lens 4 .

[0033] As a further introduction to this embodiment, the spectrum detection module 5 is provided with a slit 7 , and is connected to the spectrum collection lens 4 via the slit 7 .

[0034] As a further introduction to this embodiment, the spectrum acquisition and processing mechanism also includes a slit projection calibration mechanism 6, which can precisely adjust the inclination angle of the spectrum detection module 5 so that the projection of the groove track module 2 after passing through the spectrum collection lens 4 forms a high-precision spatial overlap with the slit 7 of the spectrum detection module 5.
