The invention discloses a tea screening machine with a hierarchical grading function, the tea screening machine comprises a box body, an inner cavity of the box body is provided with two screening frames, and the two screening frames are arranged up and down. When the tea screening machine is used, two vertical plates can be pushed to move leftwards through mutual cooperation of a transmission motor, a worm, a worm gear, a single-groove wheel, a belt, a rotating shaft and a cam; through mutual cooperation of a fixing cylinder, a first spring, a limiting plate and a cross rod, the screening frame can be reset rightwards, so that left-right shaking of the screening frame is achieved, and the screening efficiency of the tea leaves is improved; high-quality-level tea leaves, medium-level tea leaves and poor-quality tea leaves are effectively screened out, hierarchical grading of the tea leaves is completed, the hierarchical grading time of the tea leaves is effectively shortened, and the applicability is high. 本发
