A kind of tea intelligent screening device and method

Abstract

The invention discloses a tea intelligent screening device and method, comprising a box body, wherein a multi-stage screening mechanism is arranged from top to bottom in the box, each screening mechanism includes a movable grid rack and a fixed grid rack, each movable grid The racks include movable crossbars, a plurality of equally spaced and movable crossbars connected to one side of the movable grid, and each fixed grid rack includes a fixed crossbar, a plurality of equally spaced and fixed crossbars connected to the fixed grid, and the movable grid. The bars and the fixed grid bars are alternately arranged in pairs, and each movable cross bar is connected with an electric push rod arranged vertically; a linear motor is arranged above each screening mechanism, and each linear motor includes a corresponding movable grid bar. A magnetic rail arranged in the length direction and a mover slidably connected with the lower end of the magnetic rail, each mover is connected with a material pushing crossbar, and each material pushing crossbar is provided with a plurality of pushing rods downward. The invention can accurately screen the tea leaves according to their size, and effectively avoid the situation that tea leaves of different qualities are mixed together.

Description

technical field [0001] The invention relates to the technical field of tea structure, in particular to an intelligent tea screening device and method. Background technique [0002] Tea refers to the leaves or buds of the tea tree. Generally speaking, tea refers to a beverage that is processed from the leaves of the tea tree and can be directly brewed with boiling water. Tea is a dicotyledonous plant, with about thirty genera and five hundred species. In tropical and subtropical regions, there are 14 genera and 397 species in China. They are mainly produced in the south of the Yangtze River. Tea can improve human health. In the process of tea production and processing, it is necessary to sieve tea of ​​different sizes. It is convenient to screen out high-quality tea leaves and ordinary tea leaves, and is convenient for processing in different processes; the tea screening in the prior art mostly adopts manual screening, which is complicated in screening steps, consumes a lot o...

Problems solved by technology

[0002] Tea refers to the leaves or buds of tea trees. Generally speaking, tea refers to a drink that is processed from the leaves of tea trees and can be drunk directly with boiling water. Tea belongs to dicotyledonous plants, about 30 genera, 500 species, distributed In tropical and subtropical regions, there are 14 genera and 397 species in China. They are mainly produced in the south of the Yangtze River. Tea can improve human health. In the process of tea production and processing, tea leaves of different sizes need to be screened. It is convenient to screen high-quality tea leaves and ordinary tea leaves, and is convenient for processing with different processes; tea screening in the prior art mostly uses manual screening, the screening steps are cumbersome, consume more manpower, and the screening efficiency is low, which affects the production and processing efficiency of tea leaves

[0003] The existing tea screening device mainly screens the tea through the sieve through vibration, but the tea itself has many leaves and most of them are long strips. The large sieve holes of the tea leaves cannot pass through, and the small sieve holes of the vertical tea leaves can also pass through. It is difficult to determine the aperture of the sieve holes, and it is also difficult to change the state of the tea leaves through vibration. Therefore, the existing device screens tea leaves. Sometimes teas of different qualities are mixed together
