Two-layer conveyor for tea leaf spreading machine

Abstract

The invention relates to a two-layer conveyor for a tea leaf spreading machine. In the prior art, defects of high turning frequency, low equipment utilization rate and low yield by a method of matching multiple pulleys. The two-layer conveyor comprises a support, wherein the support is provided with an upper transmission mechanism and a lower transmission mechanism which are distributed up and down and of which the vertical projection parts are overlapped; the upper transmission mechanism and the lower transmission mechanism respectively comprise a plurality of horizontal guide wheel shaft in the longitudinal direction on two sides of the frame; each guide wheel shaft is provided with two symmetrically arranged main guide wheels; a closed chain is wound on main guide wheels on the same side, so two closed chains are formed; a plurality of tea leaf hoppers movably connected with the closed chains are arranged between the two closed chains; the frame is provided with two turning mechanisms matched with the tea leaf hoppers; and tea leaves pass through the turning mechanisms and are subjected to one-time transfer between the transmission mechanisms, so that the aims of turning and completely drying the tea leaves are fulfilled and the frequency of transferring, dropping and turning the tea leaves is reduced to the greatest extent.

Description

technical field [0001] The invention relates to a tea-making machine, in particular to a double-layer conveying device for a tea spreading machine. Background technique [0002] Green spreading is an indispensable step in the process of tea frying. Fresh tea picked in the open air has a large difference in dryness due to factors such as weather and storage, and tea frying requires a high degree of uniformity in the dryness of tea raw materials. Before frying, it must go through the greening process, and the temperature of the greening process is strictly controlled below 40°C. On the one hand, the tea leaves that are piled up are completely and thoroughly dried. On the other hand, the tea leaves are dried during the greening process Stirring should be avoided as much as possible to prevent damage to the tea leaves. In the prior art, the greening machine generally adopts a Z-shaped conveying mode of multiple impermeable belts, and only the upper belt surface of each belt pla...

AI Technical Summary

Problems solved by technology

In the prior art, the greening machine generally adopts a Z-shaped conveying mode of multiple impermeable belts, and only the upper belt surface of each belt plays a role in transportation, which reduces the utilization rate of the equipment, and at the same time, the transshipment between different belts causes The tea leaves have to be dropped and turned for many times, which affects the quality of the tea leaves. In order to ensure the time for the tea leaves to be roasted, the running speed of the belt must be slowed down, which also limits the processing amount of the tea leaves.
