A dust removal and feeding device for a grain color sorter

Abstract

The invention relates to a dust removal and unloading device for a grain color sorter, which includes a mounting bracket. The mounting bracket is provided with a first-level dust removal device and a second-level dust removal device located below the bottom of the first-level dust removal device. The first-level dust removal device includes an inclined setting. The screen is equipped with a gravel container fixed on the bracket below the screen. The secondary dust removal device includes two vacuum cleaners symmetrically arranged on the mounting bracket. There are two sets of brush rollers driven by motors horizontally between the two vacuum cleaners. . The beneficial effects of the present invention are: large particle impurities are removed through the sieve in the first-level dust removal device; dust or powder on the surface of the grain is brushed up by the brush roller in the second-level dust removal device, and then sucked out by a vacuum cleaner; the above-mentioned second-level dust removal The combination of the devices can remove impurities contained in the grain and dust or powder stuck to the surface of the grain, reducing dust or powder from entering the photoelectric detection system and affecting the detection structure.

Description

technical field [0001] The invention relates to the field of color sorter auxiliary equipment, in particular to a dust removal and unloading device for a grain color sorter. Background technique [0002] The photoelectric color sorter is a device that uses photoelectric detection technology to automatically sort out the different-color particles in the granular material according to the difference in the optical characteristics of the material. Photoelectric color sorter is a kind of non-destructive sorting equipment used for quality detection and classification of bulk materials. It is widely used in grain, food, pigment chemical industry and other industries. It can sort out malignant impurities such as plastic, glass, metal, and rods of the same color in grain, reaching the international leading level. As a typical opto-mechanical-electrical integration system, the color sorter involves the innovation and application of various fields of opto-mechanical, electrical and s...

AI Technical Summary

Problems solved by technology

[0003] When the grain color sorter is selecting materials, a certain amount of powder will be produced when the grain slides and wears on the slideway. At the same time, there is dust on the outside of the grain. These dust and grain powder will stick to the surface of the grain, which will greatly affect the quality of the grain.
