Technical Field

[0001] The present application relates to the technical field of seed germination rate detection, and in particular to a device for detecting the germination rate of crop seeds. Background Art

[0002] The germination rate refers to the percentage of germinated seeds in the total number of tested seeds. The germination rate is one of the important indicators for testing seed quality. It is often used to calculate the amount of seeds used in agricultural production. For example, if 95 out of 100 test seeds germinate, the germination rate is 95%. The germination rate is one of the important indicators for testing seed quality. It is often used to calculate the amount of seeds used in agricultural production.

[0003] The current detection device uses the camera on it to detect the germination rate of seeds in the incubator. However, the positions of seeds in the existing incubators are mostly fixed, which easily leads to limited coverage of the camera. Some seeds may germinate in the shadow of other seeds or be blocked by other objects, which will affect the camera's accurate recognition of their status, resulting in incomplete data and affecting the accurate assessment of the overall germination rate.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

The connecting shaft 12 can be driven to rotate by the driving mechanism, and the connecting shaft 12 can drive the two connecting frames 10 to rotate. The connecting frame 10 can drive the culture box 11 to rotate through the connecting tube 16, the connecting rod 15 and the support plate 13, and because the connecting rod 15 is rotatably arranged inside the connecting tube 16 and under the action of the seed's own gravity, the top of the culture box 11 can always face upward when it rotates around the connecting shaft 12, and the seed germination rate in multiple culture boxes 11 can be detected by the detection mechanism 4. In this process, the seeds in the culture box 11 can be driven to rotate continuously by the driving mechanism, and the seed germination rate can be detected by the detection mechanism 4, so as to avoid the germinated seeds not being accurately identified by the detection mechanism 4 under the shadow of other seeds, thereby improving the accurate evaluation of the seed germination rate.
