Description

Technical Field

[0001] The utility model relates to the field of impurity removal equipment, in particular to tea impurity removal equipment. Background Art

[0002] During the tea processing, the tea leaves will be mixed with a lot of dust and impurities, which will affect the quality of the tea. In addition, the tea leaves will be broken during the transportation and processing process, so that a large amount of tea leaves will be mixed in the finished product, which needs to be screened again to ensure the quality of the product.

[0003] When screening tea leaves, a vibrating screen bed is usually used for screening the tea leaves, and a storage hopper is fixedly installed on one side of the top of the vibrating screen bed. Tea leaves are poured into the storage hopper and then fall onto the vibrating screen bed. However, if the tea leaves are directly poured into the storage hopper, the tea leaves inside the storage hopper will automatically fall off, and the tea leaves will accumulate between the storage hopper and the vibrating screen bed. In addition, piles of tea leaves will accumulate on the vibrating screen bed, thereby reducing the tea screening efficiency and making it difficult to control the rate at which tea leaves are discharged from the storage hopper.
