Tea leaf winnowing device

Abstract

The invention discloses a tea leaf winnowing device and relates to the technical field of tea leaf winnowing. The tea leaf winnowing device comprises a winnowing box, wherein the top of the winnowing box is fixedly connected to a feeding pipe, the left side of the feeding pipe communicates with a feeding pipe with one end extending into the winnowing box, the top of the winnowing box is fixedly connected to a first motor located on the right side of the feeding pipe, an output shaft of the first motor is fixedly connected to a spiral feeding rod through a first coupler, wherein one end of the spiral feeding rod penetrates through the feeding pipe and extends into the feeding pipe. According to the tea leaf winnowing device, when tea leaves are conveyed to the feeding pipe and falls into a control box, a second motor is started, the second motor drives a rotating shaft and a rotating gear block to rotate through a second coupler, the rotating gear block stirs tea leaves into a gear tooth gap in the outer side of a rotating gear, then after the rotating gear block rotates to a certain angle, the tea leaves can fall from the control box, the tea leaves are prevented from being piled and falling off before winnowing, the purpose of scattering and falling off the tea leaves is achieved, and the winnowing quality is improved.

Description

technical field [0001] The invention relates to the technical field of tea air selection, in particular to a tea air selection device. Background technique [0002] Wind separation is a method of removing impurities by using the difference in suspension speed between materials and impurities. The purpose of wind separation is to remove light impurities and dust, and at the same time remove some heavier impurities such as stones and clods. Wind separation According to the main direction of the working airflow, the equipment is divided into three types: horizontal, vertical and inclined, among which the vertical airflow winnowing machine is the most widely used. [0003] When air-selecting tea leaves, the fan blows tea leaves of different qualities to the corresponding discharge pipes. However, when the traditional air-selection device is in use, it cannot effectively disperse the tea leaves. To improve the quality of winnowing, a kind of tea winnowing device is proposed to s...

Problems solved by technology

[0004] The object of the present invention is to provide a tea winnowing device. When the device is wind-selecting tea, the fan blows tea leaves of different qualities into the corresponding discharge pipes, so that the tea leaves can be scattered and dropped, which can solve the problem of the traditional winnowing device. When in use, the tea leaves cannot be effectively dispersed, and the tea leaves are easy to pile up and fall down, resulting in errors in winnowing and reducing the quality of winnowing
