Unhulled rice sorting device and equipment

Abstract

The invention discloses an unhulled rice sorting device and equipment and relates to the technical field of sorting equipment. The unhulled rice sorting device comprises a feeding device, an optical sorting module, a controller, a rejection device and a material chute. The feeding device communicates with the material chute through a sliding chute. The optical sorting module comprises first lightsources, second light sources, a first image collector and a second image collector; the wave length of the first light sources is 600 nm-650 nm, and the wave length of the second light sources is 380nm-760 nm; the first image collector is arranged corresponding to the first light sources and used for collecting rice transmission signals; the second image collector is arranged corresponding to the second light sources and used for collecting rice diffuse reflection signals; and the controller is electrically connected with the rejection device and the optical sorting module and used for controlling start and stop of the rejection device according to the transmission signals and/or diffuse reflection signals to sort rice to corresponding to sorting areas of the material chute. The unhulledrice sorting device can sort out bad rice with the defects such as internal damage, color difference and not full particles simultaneously.

Description

technical field [0001] The invention relates to the technical field of sorting equipment, in particular to a rice sorting device and equipment. Background technique [0002] Rice is the main food crop in the world, so sorting out high-quality rice for sowing is an important part of rice cultivation. During the maturation process of rice, it may be affected by bad weather and cannot be dried in time, which will lead to rice grain powdering, mildew and discoloration. These unhealthy rice not only have a low survival rate, but also have a certain impact on other good rice. In addition, the difference in the shape of the rice, the size and fullness of the grains also have a great impact on the germination rate, and professional equipment is required for processing to meet the required quality requirements. [0003] In the prior art, wind screening machines and gravity sorting machines are generally used to separate straw, grass clippings, weed seeds, empty grains, unfulfilled ...

AI Technical Summary

Problems solved by technology

[0004] However, when the above-mentioned method is used to screen rice, it has certain limitations, for example, it cannot accurately sort rice with cracked grains, mildew, and discoloration, which is not conducive to improving the purity of rice.
