Fresh leaf grading machine

Abstract

The invention provides a fresh leaf grading machine. The fresh leaf grading machine comprises a vibration portion component and a screening machine tool component, wherein the vibration portion component comprises a lower support seat and an upper support seat, the lower support seat is provided with a motor, a driving wheel, a driven wheel and an eccentric shaft, one end of a connection rod is connected with the eccentric shaft, the other end of the connection rod is connected with a connection rod shaft, and the connection rod shaft is installed at the bottom of the upper support seat; and the screening machine tool component comprises a rack, a material inlet hopper and a material outlet hopper, at least one segment of a groove body is arranged between the material inlet hopper and thematerial outlet hopper, the rear end of each segment of the groove body is provided with a gap bridge stirring wheel, the lower portion of each segment of the groove body is provided with a volute type material-receiving material outlet hopper, each volute type material-receiving material outlet hopper comprises a material unloading hopper and an air conveying pipe, one end of each air conveying pipe is provided with an air fan, and the other end of each air conveying pipe is provided with a material outlet pipe. According to the fresh leaf grading machine, the fact that fresh tea leaf raw materials are separated into different grades according to different sizes and lengths is met to design and develop the stepped fresh leaf grading machine, an extended arc groove screening machine tool and stepped vibration groove type structure is adopted, no jamming blocking is generated to screened fresh tea leaves, furthermore, the groove separation distance is adjustable, and the grading requirements for the fresh tea leaves of different sizes, grades and shapes are met.

Description

technical field [0001] The invention relates to the technical field of tea equipment, in particular to a fresh leaf classifier. Background technique [0002] Classification of fresh tea leaves is the first hurdle to improve the quality of tea, but the existing classification structure will bring corresponding inconvenience. In addition to jamming the tea leaves, the centralized type of material receiving is too dense for the equipment layout of the next process. It is extremely difficult and cannot be applied to an automated assembly line. [0003] Fresh tea leaves have different shapes, branches and leaves, and different sizes. The grading of fresh tea leaves cannot be framed in a suitable mesh to achieve grading. Therefore, the grading of fresh tea leaves is very concerned by users. But at present, the more common fresh tea leaf grader used in the market is a bamboo circular roll structure, which is suitable for hand-picked delicious raw materials, and the productivity is...

AI Technical Summary

Problems solved by technology

But at present, the more common fresh tea classifiers used in the market are bamboo round structure, which is suitable for fresh raw materials picked by hand, and the productivity is low, and continuous production cannot be realized.

Moreover, the sieve cylinder is easy to hang tea leaves, and the cleaning of the hanging leaves needs to be done manually after the machine is shut down, which is not suitable for the production requirements of machine-picked fresh leaves grading

In addition, there is a linear vibrating fresh leaf grading machine. Because the leaves are inserted into the mesh, it cannot be cleaned automatically. The tea leaves that block the mesh are easy to damage and affect production efficiency. This vibrating fresh leaf grading machine cannot meet the production needs.
