Tea reciprocating sifting machine

Abstract

A tea reciprocating sifting machine comprises a machine frame, a sifting bed and a drive mechanism of the sifting bed, wherein the sifting bed comprises a feed port, a discharge port and a sifting mesh module, the drive mechanism comprises bearing components. The tea reciprocating sifting machine is characterized in that the sifting bed is positioned above the machine frame in a hinged connection mode through a plurality of rocker arms which are arranged obliquely, and the lower ends of all the rocker arms are respectively hinged on the same drive frame; the sifting mesh module is arranged inside a sealed outer cover and is composed of an upper-layer sifting mesh, a lower-layer sifting mesh and a plurality of mesh-scraping elastic balls, and the plurality of mesh-scraping elastic balls are regionally arranged between the upper-layer sifting mesh and the lower-layer sifting mesh; and the drive hinged parts of the rocker arms or the drive mechanism are all provided with buffer pads. The tea reciprocating sifting machine has the advantages of being high in reciprocating sifting efficiency, little in tea contamination and low in mechanical noise and labor intensity, and is a tea refining and sifting machine which can meet the streamlined, clean and modernized mass production requirements.

Description

【Technical field】 [0001] The invention belongs to a tea processing machine, in particular to a tea shaking and sieving machine for further sieving tea in the refining process. 【technical background】 [0002] Shaking sieve is a very important link in the tea refining process, and its efficiency and quality directly determine the output and price of tea. The structure of the existing shaker consists of a frame, a sieve bed, and a transmission mechanism that drives the sieve bed to swing. The sieve bed includes a material inlet, a material outlet, and a screen. During operation, the power drives the sieve bed to vibrate through the transmission mechanism, so that the raw materials larger or smaller than the screen mesh are discharged separately to complete the screening. However, the existing tea shaker and sieve machine has the following problems in practical application: first, the spring leaf that drives the sieve bed is in a high-speed swing state for a long time, which is...

AI Technical Summary

Problems solved by technology

However, the existing tea shaker and sieve machine has the following problems in practical application: first, the spring leaf that drives the sieve bed is in a high-speed swing state for a long time, which is prone to fatigue and breaks, which not only seriously affects the service life of the spring leaf, but also As a result, the shaking efficiency is low

Secondly, the sieve bed works in an exposed state, not only the tea is susceptible to environmental pollution and affects the quality of the tea, but also the mechanical noise is large, resulting in a poor working environment, which seriously affects the physical and mental health of the operators

Furthermore, the screen needs to rely on manual scraping, which not only seriously affects the shaking efficiency of the screen, but also, the operator scrapes the screen in a shaken state, which is labor-intensive and has potential safety hazards, and cannot meet the requirements of streamlined, clean, and modern scale production. requirements, thus severely restricting the development of the tea industry
