Fresh tea classifying and screening device

Abstract

The invention relates to the technical field of fresh tea leaf classifying and screening, and discloses a fresh tea leaf classifying and screening device which comprises a conical drum screen with anintelligent controller. A first drum screen fixing plate is installed at the tea inlet end of the conical drum screen, a first drum screen rotating shaft is installed on the first drum screen fixing plate, and the first drum screen rotating shaft is connected to a first bearing; a second drum screen fixing plate is mounted at the tea outlet end of the conical drum screen, a second drum screen rotating shaft is mounted on the second drum screen fixing plate, and the second drum screen rotating shaft is connected to a second bearing; a partition plate and air cylinders are arranged in a cavity of the conical drum screen, the middle position of the tea outlet side face of the partition plate is fixedly installed on telescopic rods of the air cylinders, and an end cover of the air cylinder isfixedly installed at the middle portion of the tea inlet side face of the second drum screen fixing plate; and an output port of the intelligent controller is in communication connection with input ports of the first air cylinder, the second air cylinder and a transmission motor. The fresh tea leaf classifying and screening device solve the technical problem that fine grading of fresh tea leaves cannot be effectively achieved at present.

Description

technical field [0001] The invention relates to the technical field of fresh tea grading and screening, in particular to a fresh tea grading and screening device. Background technique [0002] The quality of fresh leaves is the foundation of the quality of Maocha, and only fine fresh leaves can produce high-quality tea. Fresh tea leaf picking methods mainly include manual picking and machine picking. Manual picking is highly identifiable to tea leaves and can control the quality of fresh tea leaves. However, manual picking is labor-intensive, low in efficiency, and high in cost. Picking of tea. The machine-picking method has poor selectivity and recognition for fresh tea leaves, but it has high efficiency and low cost, and is generally used for picking bulk tea leaves. In recent years, the effect of machine-picked fresh leaves has been significantly improved compared with traditional tea-picking equipment. However, for large quantities of high-quality tea, machine-picked f...
