Sorting mechanism capable of distinguishing grades of tea fresh leaves

Abstract

The invention discloses a sorting mechanism capable of distinguishing the grades of tea fresh leaves. The sorting mechanism comprises a sorting box and a feed mechanism; the sorting box is arranged onone side of the feed mechanism and comprises a box body rack, a vibrating feeding mechanism, a first sorting mechanism, a second sorting mechanism, a signal processor and a sensing device; the firstsorting mechanism comprises an infrared spectrum scanning device; the infrared spectrum scanning device is arranged below a first sliding chute; the light projection direction of the infrared spectrumscanning device is perpendicular to the sliding rail of the first sliding chute; an air compressor and an air-jet device are arranged below the infrared spectrum scanning device; the air-jet device communicates with the air compressor; and the air-jet device and the infrared spectrum scanning device are electrically connected with the sensing device. According to the existing near infrared spectrum special waveband of the fresh leaves, the tea fresh leaves with high grade are screened out first, then, a neural network is adopted to further analyze, screen and distinguish, and the sorting mechanism is fast, precise and effective in screening.

Description

technical field [0001] The invention relates to the technical field of sorting fresh tea leaves, in particular to a sorting mechanism for distinguishing grades of fresh tea leaves. Background technique [0002] The fresh tea leaves used to make tea are roughly divided into two types according to their grades, one is the excellent quality single-bud fresh tea leaves, and the other is the poorer one-bud one-leaf or one bud two-leaf fresh tea leaves. In the existing process, most of the tea leaves are rotated by fans to achieve the purpose of sorting through the difference in quality; such sorted fresh leaves often mix good-quality single-bud fresh leaves with poor-quality ones, and It is often mixed with some other small weeds that cannot be distinguished by winnowing. [0003] Therefore, it is very necessary to design a sorting mechanism for distinguishing the grades of fresh tea leaves. Contents of the invention [0004] The purpose of the present invention is to provide...
