[0026] Among them, the push-back device 5 includes a sleeve tube 501, a telescopic rod 502, a straight rod 503, a soft brush 504, a slot 505 and a positioning plate 506. The sleeve tube 501 is fixedly mounted on the circumferential surface of the rotating rod 8, the telescopic rod 502 is fixedly mounted on the circumferential surface of the sleeve tube 501, the straight rod 503 is fixedly mounted on the free end of the telescopic rod 502, the soft brush 504 is fixedly mounted on the front and rear ends of the straight rod 503, the slot 505 is opened at the fixed end of the telescopic rod 502, and the positioning plate 506 slides through the interior of the free end of the telescopic rod 502. When the straight rod 503 rotates, the soft brush 504 is driven to rotate. When the straight rod 503 rotates, it will contact the tea leaves accumulated on the screen 3, so that when the straight rod 503 rotates, it will push the tea leaves accumulated on the screen 3 to move in the direction away from the discharge port 10, thereby breaking up the accumulated tea leaves.
[0027] The push plate pulley device 7 includes a round head column 705, a U-shaped rod 706, a baffle 701, a connecting rod 702, a slider 703 and a rotating column 704. The round head column 705 slides through the frame 1, and the U-shaped rod 706 is fixedly installed on the side of the round head column 705 away from the telescopic rod 502. The baffle 701 is fixedly installed at the bottom of the U-shaped rod 706. A slide groove is provided inside the frame 1, and the slider 703 is slidably installed inside the slide groove. One end of the connecting rod 702 is rotatably installed on the surface of the slider 703, and the rotating column 704 is rotatably installed inside the baffle 701. The other end of the connecting rod 702 is hinged to the surface of the rotating column 704. When the baffle 701 moves, it will push the tea leaves on both sides of the screen 3 to move toward the center position to prevent the tea leaves from being stuck between the screen 3 and the frame 1, which will affect the effect of the tea leaves moving on the screen 3.
[0028] The automatic rebound mechanism 6 includes a cylindrical plate 601 and a soft film 602.

[0031] The cylindrical plate 601 and the soft film 602 are elastic, and the round head column 705 is in contact with the telescopic rod 502. The cylindrical plate 601 vibrates to drive the U-shaped rod 706 to vibrate, and the U-shaped rod 706 vibrates to drive the baffle 701 to vibrate. When the baffle 701 vibrates, the tea leaves between the baffle 701 and the screen 3 will be vibrated away to prevent the tea leaves from being stuck between the baffle 701 and the screen 3.
[0032] During operation: When tea leaves need to be screened, the telescopic end of the telescopic rod 502 in the push-back device 5 is compressed toward the fixed end, pulling the retaining plate 506 outward and removing it from the slot 505, thereby releasing the position restriction of the telescopic rod 502. The free end of the telescopic rod 502 is compressed according to the distance between the telescopic rod 502 and the screen 3, and the retaining plate 506 is pulled into the slot 505. Due to the spring inside the retaining plate 506, when the retaining plate 506 is placed in the slot 505, the spring contracts, limiting the position of the telescopic rod 502. Tea leaves are poured into the drum 2 from above the feed port 9. The drum 2 fry the tea leaves until they are dry, and then the tea leaves enter the screen 3 from below the drum 2. The screen 3 is vibrated by the vibrator 11 to screen the tea leaves. Different types of tea leaves are discharged from different discharge ports 10.

The soft brush 504 will move the accumulated tea leaves between the screen 3 and the frame 1 away from the discharge port 10, thereby breaking up the accumulated tea leaves.
[0034] When the telescopic rod 502 rotates, it contacts the arc surface of the round head column 705 in the push plate pulley device 7, so that when the telescopic rod 502 rotates, it pushes the round head column 705 to move back and forth. When the round head column 705 moves, it drives the U-shaped rod 706 to move. When the U-shaped rod 706 moves, it drives the baffle 701 to move. When the baffle 701 moves, it drives the rotating column 704 to move. When the rotating column 704 rotates, it drives the connecting rod 702 to move. When the connecting rod 702 moves, it drives the slider 703 to move in the slide groove. The baffle 701 moves. When moving, the tea leaves accumulated on both sides will be pushed toward the middle to prevent the tea leaves from entering between the screen 3 and the frame 1 and causing jamming. When the U-shaped rod 706 moves, it will drive the cylindrical plate 601 in the automatic rebound mechanism 6 below to move. When the cylindrical plate 601 moves, it will come into contact with the soft film 602 below. The cylindrical plate 601 vibrates and drives the U-shaped rod 706 to vibrate. The U-shaped rod 706 vibrates and drives the baffle 701 to vibrate. When the baffle 701 vibrates, the tea leaves between the baffle 701 and the screen 3 will be vibrated away to prevent the tea leaves from getting stuck between the baffle 701 and the screen 3.
