The top of the tea conveyor 1 is located at the tea inlet 4. A multi-layer belt conveyor 8 is arranged on the other side of the tea screening machine 2. The multi-layer belt conveyor 8 is composed of a plurality of conveyor belts 7. A screening machine inner cavity 14 is provided on the front of the tea screening machine 2. Vibration plates 10 are arranged at the centers of both sides of the tea screening machine 2. A vibrator 9 is fixedly connected to the front center of the vibration plate 10. The back of the vibration plate 10 is provided with a plurality of conveyor belts 7. Three vibration blocks 11 are arranged longitudinally at the center of the surface, and the back of the vibration block 11 is located in the inner cavity 14 of the screening machine. A screening plate 15 is arranged between the vibration blocks 11 on different sides and in the same horizontal plane, and a fixed plate 12 is arranged at the bottom of the back of the vibration block 11. There are through grooves on both sides of the center of the screening plate 15, and the bottom of the screening plate 15 is in contact with the top of the fixed plate 12. The through groove is the part where the vibration block 11 is located in the inner cavity 14 of the screening machine, and tea outlets 5 are arranged at both ends on the other side of the top of the screening plate 15, and the other end of the tea outlet 5 is located at the conveyor belt 7, and the other ends of the tea outlets 5 at different heights are located at the conveyor belt 7 at different heights.

[0019] Furthermore, a through hole is provided at the center of the surface of the fixing plate 12 , and a fixing hole is correspondingly provided on the surface of the screening plate 15 , and the fixing hole and the through hole are connected via a fixing pin 13 .

[0020] Furthermore, a maintenance door 3 is provided on one side of the opening surface of the tea sieving machine 2 through a hinge, and the other side of the maintenance door 3 is connected to the other side of the tea sieving machine 2 through a key lock.
