Multistage differential fresh tea leaf sorting and single-column conveyor and single-column conveying method thereof

Abstract

The invention discloses a multistage differential fresh tea leaf sorting and single-column conveyor and a single-column conveying method thereof. A conventional tea leaf winnower is not ideal enough in sorting effects. The multistage differential fresh tea leaf sorting and single-column conveyor comprises a multistage differential conveyor, a discharger and a cross-flow fan group system. The method disclosed by the invention comprises the following steps of firstly, performing winnowing on fresh tea leaves fed from the discharger through a stable flow field manufactured by cross-flow fans, wherein the winnowed tea leaves fall into a dual-layer material conveyer which comprises an upper layer and a lower layer, the upper layer is provided with two conveyer belts mounted on two sides, and the lower layer is provided with a conveyer belt mounted at a middle position where the falling tea leaves can be divided into three rows for transmission; and through two-stage conveyer belts of which the speed is continuously increased, enabling the distances between front tea leaves and rear tea leaves to be enlarged, so that harmless classification and single separation on the tea leaves of different stages are realized. According to the multistage differential fresh tea leaf sorting and single-column conveyor disclosed by the invention, the fresh tea leaves falling off from a discharge opening are winnowed, the dual-layer conveyer belt design is used for realizing single-column treatment, and the winnowing manner and the conveyer can effectively reduce damage to the fresh tea leaves in the classification process.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to a conveyor, in particular to a high-efficiency, low-loss multi-stage differential fresh-leaf sorting single-row conveyor and a single-row conveying method. Background technique [0002] China is a big tea producing and exporting country. There are many varieties of tea, and the tea-making process of different tea leaves is quite different, but generally speaking, they can be divided into picking, sorting, drying, kneading, sub-packaging, cold storage and other processes. Although manual tea picking is complete in picking buds and leaves, the efficiency is very low and the cost is high. In order to improve labor efficiency and develop the tea industry, many tea gardens are currently using mechanized tea picking equipment. The labor efficiency of these mechanized equipment is very high, but the integrity of tea picking is not high, which leads to a lot of consumption in subsequent processin...
