Intelligent classification device for machine-picked fresh tea

Abstract

The present invention relates to an intelligent classification device for machine-picked fresh tea, and belongs to the agriculture and forestry mechanical technology field. The device comprises a control portion and a rotating disk, the periphery of which is orderly provided with a feeding device, a tea position finder, a camera, and a set of sorters in a circumferential direction. Each sorter comprises a chain driving mechanism arranged on a frame, with a hairbrush, which is capable of brushing with a chain in a direction from the central part to the edge of the rotating disk, being arranged outside of a driving chain of the chain driving mechanism, and a hairbrush in-position induction device for controlling a hairbrush stop position being arranged in the driving chain. The signal output end of the tea position finder is connected with a corresponding signal input end of an one-chip microcomputer control circuit, the signal output end of the camera is connected with an image signal input end of a PC, and the control output ends of the one-chip microcomputer control circuit are respectively connected with the controlled ends of chain driving mechanisms. The device can high-effectively and automatically finish the whole process of tea classification.

Description

technical field [0001] The invention relates to a tea classification device, in particular to an intelligent classification device for machine-picked fresh tea, which belongs to the technical field of agricultural and forestry machinery. Background technique [0002] At present, mechanical tea picking is more and more widely used. However, various grades of tea leaves are mixed together in machine-picked fresh tea leaves, and there will be more impurities such as broken tea leaves, tea stems and non-tea plant leaves. After this mixed tea of ​​various grades is made into finished tea, its grade will be greatly reduced. Equipment that uses the physical properties of tea leaves for sorting (such as winnowing, screening, and gravity sorting) can remove most impurities, but it cannot complete the grading of tea leaves, and some impurities with similar physical characteristics to tea leaves are also difficult to remove. Another kind of sorting equipment is the tea color sorter, ...

AI Technical Summary

Problems solved by technology

Equipment that uses the physical characteristics of tea leaves for sorting (such as winnowing, screening, and gravity separation) can remove most impurities, but cannot complete the grading of tea leaves, and some impurities with similar physical characteristics to tea leaves are also difficult to remove

Another kind of sorting equipment is tea color sorting machine, this kind of equipment can only be used to remove the leaf stalks in the processed tea leaves, it cannot be used for fresh tea leaves, and it cannot identify the grade category of tea leaves

Therefore, at present, the machine-picked tea can only be sorted manually to obtain high-grade fresh tea.
