[0033] The implementation principle of a shaking screen device for tea sorting in the present application is as follows:

[0034] First, place the tea leaves on top of the screen 10 inside the "mouth" shaped fixed frame 9, start the bidirectional motor 3 above the support block 2, and the bidirectional motor 3 drives the No. 1 connecting rod 4 on both sides to rotate through the shafts on both sides.

The No. 2 connecting rod 6 can rotate inside the "U" shaped fixed block 7 on one side of the "mouth" shaped fixed frame 9, and at this time drives the "mouth" shaped fixed frame 9 to vibrate horizontally inside the horizontal slide groove 8.

[0035] Secondly, when the tea leaves above the screen 10 are vibrated, they are separated from the impurities inside. At this time, the impurities are collected by connecting the collecting box 12 through the connecting plate 11 below the "mouth"-shaped fixed frame 9. Then, under the influence of vibration, the impurities are displaced from the slope inside the collecting box 12 to the conveying trough 13 for discharge.

[0036] Finally, when the screen 10 is blocked, the small motor 14 is started, and the small motor 14 drives the fixed plate 16 on the second shaft 15 to change from a vertical state to a horizontal state. At this time, the cylinder 17 on one side of the fixed plate 16 drives the protrusion 20 on the positioning plate 19 to move. At this time, when the protrusion 20 moves to the inside of the hole of the screen 10, the cleaning is completed.
