When the grains are discharged, they are irradiated by the infrared lamp assemblies 50 on both sides of the discharge end of the vibrating conveyor belt 30. When the infrared lamp assemblies 50 irradiate the grains, they can confirm the reflected light of the grains, and then the first camera assembly 60 photographs the grains, and then the first camera assembly 60 compares the reflected light of the photographed grains according to the preset spectral information, so as to judge whether the grains are heterochromatic particles. If they are heterochromatic particles, they are defective grains. After the grains are color-identified by the infrared light assembly 50, the grains are illuminated by the fill light assembly 70 on both sides of the unloading end of the vibrating conveyor belt 30. At this time, the fill light assembly 70 will fill light on the grains, and then the second camera assembly 80 will shoot the grains. Then the second camera assembly 80 will compare the shape of the photographed grains according to the pre-set grain shape information, so as to judge whether the grain shape is complete. If the grain shape is incomplete, it is broken grain. In the utility model, on the one hand, the infrared light assembly 50 cooperates with the first camera assembly 60 to identify the color of the grains, so as to judge the different-colored particles; on the other hand, the fill light assembly 70 cooperates with the second camera assembly 80 to identify the shape of the grains, so as to judge the broken grains; by detecting the grains from these two aspects, the grains can be efficiently and accurately sorted and identified.

[0035] In specific implementation, after the grains pass through the infrared light assembly 50 and the first camera assembly 60 to detect the color, and the grains pass through the fill light assembly 70 and the second camera assembly 80 to detect the shape, if the color and shape of the grains are normal, the grains will directly fall into the feeding port 10011 of the feeding channel 1001 located just below the feeding end of the vibrating conveyor belt 30 for feeding, and if the color and / or shape of the grains are defective, the air nozzle 90 will blow the defective grains into the feeding port 10011 of the feeding channel 1001 located on the other side of the feeding end of the vibrating conveyor belt 30 for feeding according to the detection signals of the first camera assembly 60 and / or the second camera assembly 80.
