[0002] Tea is a common brewed beverage. When processing tea, the tea raw materials need to undergo a variety of processes, such as withering, rolling and drying. After the tea is dried, the impurities and soil in the tea need to be screened out through an impurity screening device to ensure the cleanliness of the tea and improve the quality of subsequent products.
[0003] The existing tea impurity screening device generally places the tea leaves on a sieve plate and screens and separates the tea leaves through the sieve plate. When the tea leaves are screened through a plate screen, the screen is prone to clogging during continuous use, resulting in a decrease in the screening effect.

However, the vibration amplitude of the screen driven by the vibration motor is relatively small. If the tea leaves are large, the screen will still be blocked, thereby reducing the screening efficiency of the impurity screening mechanism. Therefore, an impurity screening mechanism made of tea leaves is proposed to solve the above problem. Utility Model Content

[0025] In an optional embodiment, the driving assembly 7 includes a driving DC motor 701, an L-shaped plate 702, a rotating shaft 703 and a driving gear 704.
