When the staff picks tea leaves, the picked tea leaves can be placed inside the classification box 3 through the feeding hole on the top surface of the classification box 3, and the picked tea leaves can be initially sorted through the sieve plate 4. When the picking is completed, the vibration motor 11 is started by the external PLC. After the vibration motor 11 is started, it can drive the vibration plate 10 to vibrate. The vibration of the vibration plate 10 drives the classification box 3 fixed thereto to vibrate. The classification box 3 vibrates under the support of several support columns 12, several springs 13 and several gaskets 14. The vibration of the classification box 3 drives the sieve plate 4 fixed thereto to vibrate, so that the tea leaves on the top surface of the sieve plate 4 can be screened;

[0044] When the screening is finished, the vibration motor 11 is turned off and the motor 79 is started through the external PLC. The output shaft of the motor 79 rotates to drive the rotating shaft 710 coaxially connected thereto to rotate. The rotating shaft 710 rotates to drive the gear 78 coaxially fixed thereto on the same side to rotate. The gear 78 rotates to drive another gear 78 meshing therewith to rotate. The other gear 78 rotates to drive the rotating rod 77 coaxially fixed thereto to rotate. The rotating rod 77 rotates to drive the rotating column 72 coaxially fixed thereto on the same side to rotate. The rotating column 72 rotates to drive the screw 73 coaxially fixed thereto to rotate. The screw 73 rotates to drive the moving rod 74 threadedly connected thereto to move. The moving rod 74 moves along the guide block 76 with a The movable rod 74 moves upward under the guidance of the guide groove on the right side surface of the classification box 3, thereby driving the baffle 5 fixed thereto by the connecting rod 75 to move upward. When the baffle 5 moves to cover the upper discharge chute but not the lower discharge chute, the motor 79 is turned off by the external PLC, so that the tea leaves on the bottom surface of the classification box 3 can be unloaded. After unloading, the motor 79 is started by the external PLC. According to the above, the output shaft of the motor 79 rotates to drive the baffle 5 to move upward. When the baffle 5 moves to a position where it no longer covers the upper discharge chute and the lower discharge chute, the motor 79 is turned off by the external PLC, so that the tea leaves on the top surface of the sieve plate 4 can be unloaded.
