Fresh tea leaf grading machine

Abstract

The invention discloses a fresh tea leaf grading machine, which comprises a stander, a material feeding hopper, a power device and a screening device, wherein the screening device comprises a plurality of coaxial rotary screening barrels; a plurality of spiral material guide ribs are arranged on the inner wall of the barrel body of each screening barrel; the screening barrels are fixedly connected with one another; the apertures of screening holes of the screening barrels are reduced gradually from inside to outside; an outer barrel is coaxially arranged on the outermost screening barrel; the material feeding hopper is connected with the front end of the innermost screening barrel through a connection channel; openings are formed at the tail ends of the screening barrels; and the power device can drive the screening barrels to rotate. The fresh tea leaf grading machine has functions of turning and throwing and pushing fresh leaves to flow towards outlets at the tail ends through the material guide ribs, so that fresh tea leaves with different sizes can be graded effectively according to the sizes; the screening quality is high; the fresh tea leaf raw materials for producing qualified teas can be automatically obtained; the labor intensity is reduced greatly; and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of tea processing equipment, in particular to a device for continuously grading fresh tea leaves. Background technique [0002] In recent years, the difficulty of picking famous and high-quality tea has become a practical problem and technical bottleneck restricting the sustainable development of famous and high-quality tea. Although the picking effect of famous and high-quality tea is significantly improved compared with traditional tea picking equipment, the tea gardens in my country are complex in appearance, shaggy, and growing. It is difficult to use fresh leaves picked by machine, and it is necessary to sieve them. At present, the traditional equipment for fresh leaf screening has no obvious classification effect during use, the amount is not large, and it is difficult to be continuous. The tea industry is a labor-intensive industry. With the increasingly obvious problem of labor shortage, the product...

Problems solved by technology

However, this structure adopts screening holes with different apertures arranged in sections, and the fresh tea leaves use the inclination angle to realize the downward flow, and only rely on the rolling of the cylinder to make the fresh tea leaves sieve holes. Thoroughly, after screening, fresh tea leaves of different sizes appear in the same grade area, and the fresh tea leaf raw materials required for the production of famous tea cannot be obtained through automated operations
