Abstract

The invention discloses an automatic sorting device for tea leaves, which comprises a frame, on which a sand removal pipe is horizontally arranged, the upper side of the sand removal pipe is connected with a hopper, the lower side of the sand removal pipe is provided with a through hole, and one end of the sand removal pipe is There is a fan connected to it, a filter screen is provided on the side of the other end of the sand removal pipe, and a wind collecting hood is provided on the side of the filter screen away from the sand removal pipe, the wind collecting hood is connected to a ventilation pipe, and a The drop tube is provided with a tea sorting mechanism under the down tube. The tea sorting mechanism includes a disc on which at least two annular filter plates are arranged. A collection box is slidingly arranged under each filter plate. The collection box Fixedly connected to the frame, the center of the disc is connected with the first rotating shaft, the ventilation pipe is provided with a windmill, the windmill is connected with the second rotating shaft, both the first rotating shaft and the second rotating shaft are connected to the frame in rotation, the first rotating shaft A transmission mechanism is connected with the second rotating shaft; compared with the prior art, the present invention has better sorting effect.

Description

technical field [0001] The invention relates to the field of agricultural product processing, in particular to an automatic sorting device for tea leaves. Background technique [0002] The quality of fresh leaves is the basis of tea quality, and only good fresh leaves can process high-quality tea. Because of the high efficiency and low cost of mechanical picking, it has been widely used by tea farmers at present. However, the selectivity and identification of fresh leaves by mechanical picking are poor. After mechanical picking, the picked tea leaves need to be screened and graded. After sorting and archiving, the tea leaves with different leaf buds are processed in a targeted manner in order to produce high-quality bulk tea. At present, the fresh leaf screening equipment in my country is mainly made of bamboo drum screen fan. The equipment uses bamboo strips as the material and weaves it into a drum full of screen holes. The motor drives the drum to rotate, and the fresh l...

Problems solved by technology

[0004] Although the above-mentioned scheme ensures the normal operation of the sieve cylinder and improves the efficiency of screening through the setting of the fan, there are still the following problems: because the tea leaves picked by machinery are generally covered with a small amount of impurities such as sand and stones, it is difficult to carry out tea sorting. These impurities need to be removed to ensure the qu
