[0022] A locking seat 13 is fixedly welded on a side wall of the support frame 2 away from the rotating seat 3, and a stud 14 is slidably connected to the locking seat 13. The stud 14 is threadedly connected to the side wall of the screening bucket 4. The screening bucket 4 can be locked on the support frame 2 by the arranged locking seat 13 and stud 14 to prevent the screening bucket 4 from shaking during screening.

[0023] The screening bucket 4 is provided with a cover plate 15, on which a sealing plate 16 is fixedly welded. Two buckles 17 are installed on the screening bucket 4. The buckles 17 provided on the cover plate 15 are buckled on the screening bucket 4. The cover plate 15 can be easily disassembled and assembled through the provided buckles 17. After the cover plate 15 is covered, the screening bucket 4 can be sealed by cooperating with the sealing plate 16 to prevent tea from leaking out during screening.

[0024] The collecting box 1 is provided with a discharge port 18 , to which a box door 19 is hinged. The discharge port 18 is convenient for discharging the screened residue from the collecting box 1 .

[0025] A scraper 20 is provided on the inner wall of the collecting box 1 on the side away from the discharge port 18, and a push rod 21 is fixedly welded on the scraper 20. The push rod 21 is slidably connected to the side wall of the collecting box 1.

[0026] Four supporting legs 22 are fixedly welded on the bottom wall of the collecting box 1, and a fixing plate 23 is fixedly welded on the bottom wall of the supporting legs 22. The fixing plate 23 is provided with fixing holes 24, and the fixing holes 24 can be used to fix the fixing plate 23 by means of fastening bolts to prevent the collecting box 1 from shaking or shifting during screening.

[0027] Working principle: When the utility model is in use, the cover plate 15 is opened, and the tea leaves are put into the screening bucket 4. Then, the buckle 17 is fastened and the driving motor is started. The driving motor drives the cam 12 to rotate and circulates the roller 11. When the roller 11 is squeezed, it can drive the support frame 2 to move upward and stretch the spring 10 through the slider 9. When the cam 12 rotates away from the roller 11, the stretched spring 10 is restored, driving the support frame 2 to reset, so that when the cam 12 rotates, the support frame 2 can vibrate up and down, thereby driving the screening bucket 4 to vibrate up and down, screen the tea leaves, and screen the residue in the tea leaves into the collection box 1 for collection, so as to clean the residue in the tea leaves. After the screening is completed, the cover plate 15 is opened, and the stud 14 is screwed to make the stud 14 separate from the screening bucket 4, and the tea leaves can be poured out of the screening bucket 4 by turning over the screening bucket 4.
