A screen frame 4 is arranged inside the screening box 2, and one end of the screen frame 4 is arranged as an opening structure. A driving mechanism for driving the screen frame 4 to reciprocate is arranged inside the screening box 2, and a guide plate 3 is fixedly installed inside the screening box 2. When in use, pour tea leaves into the feed box 1, start the cylinder 10, and make the cylinder 10 drive the dividing block 18 to move horizontally. When the vertical hole of the receiving block is aligned with the outlet of the feed box 1, the tea leaves can fall from the feed box 1 into the vertical hole of the dividing block 18. At this time, the bottom of the vertical hole is supported by the screening box 2. When the vertical hole is filled with tea leaves, The cylinder 10 drives the dividing block 18 to move toward the feeding port of the screening box 2 until the bottom of the vertical hole of the dividing block 18 is aligned with the feeding port, so that the tea leaves can fall from the vertical hole through the feeding port into the screening box 2 for screening. The dividing block 18 is operated reciprocatingly in this way, so that the amount of tea leaves falling each time can be the same, thereby reducing the phenomenon that more or less tea leaves are poured into the screening process, which affects the screening efficiency and screening quality. By setting the screw 12, the control plate 9 is driven to move in the vertical hole of the dividing block 18 by rotating the screw 12, and the channel of the vertical hole is adjusted, so that the amount of tea leaves entering the vertical hole can be controlled, further enhancing the practicality of the device. The auxiliary mechanism is started to help the tea leaves to be discharged, so as to avoid the phenomenon that the tea leaves cannot fall smoothly from the feed box 1 due to the accumulation of tea leaves. The driving mechanism inside the screening box 2 drives the screen frame 4 to vibrate reciprocatingly to screen the tea leaves inside the screen frame 4. The smaller tea leaves will fall from the mesh at the bottom of the screen frame 4 to the guide plate 3 and slide out using the guide plate 3. The tea leaves that meet the standards will be discharged from the discharge port of the screen frame 4. The amount of tea leaves screened is controlled by setting the dividing block 18 and the control panel 9, which accelerates the screening efficiency and improves the screening effect.

The inclined setting of the guide plate 3 makes it convenient for small tea leaves to slide directly out of the guide plate 3. The ports of the guide plate 3 and the screen frame 4 are exposed from the screening box 2, which facilitates the discharge of tea leaves from the inside of the screening box 2, and is convenient for practical use.
[0029] Furthermore, the driving mechanism includes a second motor 13, which is fixedly mounted on the top wall of the screening box 2, and a turntable 19 is fixedly mounted on the output port of the second motor 13, and a rotating shaft is fixedly mounted on the bottom of the turntable 19 near the edge, and a connecting rod 14 is rotatably connected to the surface of the rotating shaft, and one end of the connecting rod 14 is rotatably connected to the screen frame 4. When in use, the driving mechanism starts the second motor 13, and the second motor 13 drives the turntable 19 to rotate, and the turntable 19 drives the surface connecting rod 14 to move, and the port of the connecting rod 14 is rotatably connected to the screen frame 4, so that the circular motion of the turntable 19 can be converted into a linear motion of the screen frame 4, thereby causing the screen frame 4 to vibrate back and forth to screen the tea leaves inside.
[0030] Furthermore, horizontal rods 11 are fixedly installed on both sides of the screen frame 4, and the inner wall of the screening box 2 is provided with horizontal grooves 15 that are adapted to the size of the horizontal rods 11.

The reciprocating operation of the dividing block 18 can make the amount of tea leaves falling each time the same, thereby reducing the phenomenon that more or less tea leaves are poured in during the screening process, affecting the screening efficiency and screening quality. A screw 12 is provided, and by rotating the screw 12, the control plate 9 is driven to move in the vertical hole of the dividing block 18, and the channel of the vertical hole is adjusted, so that the amount of tea entering the vertical hole can be controlled, and the practicability of the device is further enhanced. In the process of unloading, the auxiliary mechanism can be started to help the tea leaves to be discharged, so as to avoid the phenomenon that the tea leaves cannot fall smoothly from the feed box 1 due to the accumulation of tea leaves. The driving mechanism inside the screening box 2 drives the screen frame 4 to vibrate reciprocally to screen the tea leaves inside the screen frame 4. Smaller tea leaves will fall from the mesh at the bottom of the screen frame 4 onto the guide plate 3, and slide out using the guide plate 3. Tea leaves that meet the standards will be discharged from the discharge port of the screen frame 4. The dividing block 18 and the control plate 9 are provided to realize the control of the amount of tea leaves to be screened, and the tea leaves can be easily discharged. The invention can speed up the screening efficiency and improve the screening effect. The feed box 1 is provided so that all the tea leaves to be screened can be poured in, and there is no need to repeatedly feed the tea leaves, which improves the working efficiency and is convenient for practical use. The screen frame 4 is tilted so that when the driving mechanism drives the screen frame 4 to vibrate back and forth, the tea leaves can be moved from a high place to a low place, thereby facilitating the automatic discharge of the tea leaves. The guide plate 3 is tilted so that small tea leaves can slide out directly from the guide plate 3. The ports of the guide plate 3 and the screen frame 4 are exposed from the screening box 2, which is convenient for the tea leaves to be discharged from the inside of the screening box 2, and is convenient for practical use. When the driving mechanism is in use, the second motor 13 is started, and the second motor 13 drives the turntable 19 to rotate, and the turntable 19 drives the surface connecting rod 14 to move, and the port of the connecting rod 14 is rotatably connected with the screen frame 4, so that the turntable 1 9 The circular motion of the rotation can be converted into the linear motion of the screen frame 4, so that the screen frame 4 can vibrate back and forth to screen the tea leaves inside. The horizontal rod 11 and the horizontal groove 15 are arranged to make the screen frame 4 move more stably during the reciprocating vibration. When the auxiliary mechanism is in use, the first motor 6 is started, and the first motor 6 drives the stirring shaft 7 to rotate. The rotation of the stirring shaft 7 drives the stirring rod 8 to rotate, so that the stirring rod 8 stirs the tea leaves at the outlet of the feed box 1 to prevent the accumulation of tea leaves from blocking the outlet and preventing the tea leaves from leaking out. When the screen frame 4 is screening the tea leaves, the vacuum cleaner 5 is started. When the screen frame 4 vibrates, the dust inside the tea leaves will fly inside the screening box 2.
