Optical sorting device and optical sorting equipment for sorting deteriorated rice seeds

Abstract

The application discloses an optical sorting device for sorting deteriorated rice seeds. The optical sorting device comprises an optical system, an analysis system and a transfer system, wherein the optical system comprises a light source and an image acquisition component; the wavelength provided by the optical source is 600 to 650nm; light emitted by the light source penetrates through rice seeds in an image acquisition area and then is acquired by the image acquisition component; the analysis system is used for receiving an image acquired by the image acquisition component and analyzing theimage; the transfer system is connected with the analysis system and respectively transfers the rice seeds to corresponding sorting areas according to the analysis result of the analysis system. Theapplication also provides optical sorting equipment for the rice seeds. According to the scheme provided by the application, recognition and sorting of the deteriorated rice seeds such as preharvest sprouting, rice grain powder and mildew are realized, and the effect of improving the germination percentage of the rice seeds is obvious.

Description

technical field [0001] The present application relates to the technical field of sorting equipment, in particular to an optical sorting device and equipment for sorting deteriorating rice seeds. Background technique [0002] During the mature harvesting period and drying process of hybrid rice seeds, if the harvesting is delayed or cannot be dried in time due to adverse weather such as rainfall, some seeds will suffer from deterioration phenomena such as ear germination, rice grain siltyness, and mildew and discoloration. Most of the changed seeds can't germinate into seedlings or have very low vigor and have no seed value, and the deteriorated seeds will also affect the normal germination of other non-deteriorated seeds in the same batch of seeds. The size and grain weight of these deteriorated seeds are not significantly different from those of non-deteriorated seeds, and it is difficult to sort them out by using existing methods such as wind screening and gravity selectio...

Problems solved by technology

[0002] During the mature harvesting period and drying process of hybrid rice seeds, if the harvesting is delayed or cannot be dried in time due to adverse weather such as rainfall, some seeds will suffer from deterioration phenomena such as ear germination, rice grain siltyness, and mildew and discoloration. Most of the altered seeds cannot germinate into seedlings or have very low vigor, which is useless for seed use, and the deteriorated seeds will also affect the normal germination of other unmodified seeds in the same batch of seeds

The size and grain weight of these deteriorated seeds are not significantly different from those of non-deteriorated seeds, and it is difficult to sort them out by using existing methods such as wind screening and gravity selection; Most of the glumes have no obvious change, and the existing color sorting and even water sorting methods are difficult to separate the deteriorated seeds, resulting in the reduction or even loss of the seed value of the whole batch of seeds. Scrap, causing considerable losses to seed farmers and seed companies
