Description

Technical Field

[0002] Imperfect grains refer to grains that are damaged but still have edible value, including insect-eaten grains, diseased grains, broken grains, immature grains, sprouted grains and moldy grains. Imperfect grains are easily produced during the production, storage, packaging and transportation of grain, which seriously affects the quality and safety of grain. At present, the quality inspection of grain is mostly done manually, and the speed of manual inspection is relatively slow. The quality results of the inspection are very subjective. In recent years, with the continuous development of computer vision technology, people have also applied this technology to the detection of imperfect grains. The grain is photographed and sorted through computer vision technology. However, this technology requires the grain to be displayed separately under the camera equipment, and the piled grain will affect the sorting results.

[0003] To solve the above problems, the prior art patent (CN217017476U) discloses a sorting mechanism based on the detection of imperfect grains in grain, including a conveying mechanism, an evacuation mechanism and a sorting mechanism, wherein the conveying mechanism is provided with an evacuation mechanism for evacuating and spreading the accumulated grain, and the right side of the conveying mechanism is provided with a sorting mechanism for sorting the grain, the conveying mechanism comprises a conveyor belt, the left and right sides of the conveyor belt are respectively connected with an active roller and a driven roller, the active roller is connected to the output shaft end of the rotating motor, and the active roller sleeve is provided with a first bevel gear; through parts such as a fixed plate, a connecting rod, a turntable, a second rotating rod and a second roller, the sliding brush can be moved back and forth above the conveyor belt to evacuate and spread the accumulated grain on the conveyor belt so that the grain will not be stacked together, thereby ensuring that the machine vision device can identify each grain of grain and improve the sorting quality.

[0004] However, in the above-mentioned prior art, spreading the grains only by means of a brush will cause a large amount of grains on a plane to fall into the sorting mechanism at the same time, which will affect the sorting accuracy of the material striking and sorting device.
