PHOTOELECTRIC SORTING DEVICE FOR COLOR SORTING APPARATUS

摘要

A photoelectric sorting device of a color sorting apparatus adapted to sort grains according to their colors. The photoelectric sorting device includes a pair of photoelectric chambers 9, 10 disposed within a grain sorting chamber 12 located under a grain chute 3 of the sorting apparatus, in such a manner that the photoelectric chambers 9, 10 opposes to each other across the flux 4 of flow of the grains coming down from the chute. Each of the photoelectric chambers 9, 10 is shielded from the grain sorting chamber by means of a transparent window plate 11 and accommodates a photoelectric detector 5, 6, 15, 17; 7, 8, 16, 18. At least one of the photoelectric chambers 9, 10 is rotatably mounted on the frame of the particle sorting chamber 12 to facilitate the cleaning of the transparent window plates 11.
