A plurality of movable plates 3 are arranged inside the screening body 1, and the movable plate 3 is arranged below the filter plate 8. The movable plate 3 can facilitate the discharge of the screened tea leaves through different widths. A conveying platform 4 is fixedly arranged on the bottom surface of the screening body 1, and a conveyor belt is installed inside the conveying platform 4. The bottom surface of the movable plate 3 is slidably connected to the top surface of the conveyor belt, and the conveyor belt can transport and discharge the screened tea leaves, and supporting legs 5 are fixedly arranged at the four corners of the bottom surface of the conveying platform 4.

[0026] like Figure 1-Figure 3As shown, an adjustment component is arranged inside the screening body 1, and the adjustment component consists of an adjustment slot 7, an inclined slot 9 and an inclined block 10. The outer wall of the screening body 1 is provided with an adjustment slot 7, and the inner wall of the screening body 1 is provided with an inclined slot 9. The adjustment slot 7 is communicated with the inclined slot 9. An inclined block 10 adapted to the inclined slot 9 is fixedly arranged on the side of the movable plate 3. The inclined block 10 is slidably connected to the screening body 1 through the inclined slot 9. The inclined slot 9 cooperates with the inclined block 10 to guide the movement of the movable plate 3. The inclined inclined slot 9 can make the tea leaves entering the inside of the inclined slot 9 return to the inside of the screening body 1 along the bottom surface of the inclined slot 9 to avoid the tea leaves from accumulating inside the inclined slot 9.

[0027] like Figure 1-Figure 4 As shown, a baffle 6 is hingedly connected to the outer wall of the screening body 1 , and closing the baffle 6 can cover the adjusting slot 7 , thereby preventing the screened tea leaves from falling to the outside of the screening body 1 through the chute 9 and the adjusting slot 7 .

[0028] like Figure 1-Figure 4 As shown, a limit assembly is provided on the side of the movable plate 3, and the limit assembly consists of a pull plate 11, a handle 12, a block 13, a slot 14, a slide 15, a connecting rod 16, a spring 17 and a sliding plate 18. A handle 12 is provided inside the adjusting slot 7, and a pull plate 11 is fixedly provided on the side of the handle 12, and a block 13 is fixedly provided on the other side of the pull plate 11. A slot 14 adapted to the block 13 is provided inside the screening body 1, and the block 13 is slidably connected to the screening body 1 through the slot 14. A slide 15 is provided inside the tilting block 10, and a spring 17 is fixedly provided on the inner wall of the slide 15, and a sliding plate 18 is fixedly provided on the other end of the spring 17. The outer side of the sliding plate 18 is slidably connected to the inner wall of the slide 15, and a connecting rod 16 is fixedly provided on the side of the sliding plate 18 close to the spring 17, and the connecting rod 16 passes through the tilting block 10 and is fixedly connected to the pull plate 11 When the position of the movable plate 3 needs to be adjusted, the baffle 6 is opened and the handle 12 is moved outward to drive the pull plate 11, the block 13, the connecting rod 16 and the sliding plate 18 to move outward, and the spring 17 is compressed until the distance between the sliding plate 18 and the pull plate 11 reaches the minimum. At this time, the block 13 has been separated from the slot 14, and the handle 12 is moved back and forth to drive the pull plate 11 and the tilting block 10 to move back and forth, thereby adjusting the position of the movable plate 3. After the position adjustment is completed, the block 13 is aligned with the nearest slot 14 and the handle 12 is released. The spring 17 pushes the sliding plate 18 to move inward, thereby driving the block 13 to extend into the slot 14, limiting the position of the movable plate 3, and multiple movable plates 3 can move horizontally in the screening body 1, thereby changing the distance between adjacent movable plates 3, improving the applicability of the device, and meeting more production needs.

[0029] Specific working principle:

[0030] When the device is in use, tea leaves are poured into the feed port 2, and the filter plate 8 is used to screen tea leaves of different sizes. The screened tea leaves fall onto the top surface of the conveyor belt, and the movable plate 3 cooperates with the inner wall of the screening body 1 to separate the tea leaves into different widths. The inclined chute 9 can make the tea leaves entering the chute 9 return to the screening body 1 along the bottom surface of the chute 9 to avoid the tea leaves from accumulating inside the chute 9. The conveyor belt drives the screened tea leaves to move and discharge.

[0031] When the position of the movable plate 3 needs to be adjusted, the baffle 6 is opened and the handle 12 is moved outward to drive the pull plate 11, the block 13, the connecting rod 16 and the sliding plate 18 to move outward. The spring 17 is compressed until the distance between the sliding plate 18 and the pull plate 11 reaches the minimum. At this time, the block 13 has disengaged from the slot 14, and the handle 12 is moved back and forth to drive the pull plate 11 and the tilting block 10 to move back and forth, thereby adjusting the position of the movable plate 3. The inclined slot 9 cooperates with the tilting block 10 to guide the movement of the movable plate 3. After the position adjustment is completed, the block 13 is aligned with the nearest slot 14 and the handle 12 is released. The spring 17 pushes the sliding plate 18 to move inward, thereby driving the block 13 to extend into the slot 14, limiting the position of the movable plate 3. Multiple movable plates 3 can move horizontally in the screening body 1, thereby changing the distance between adjacent movable plates 3, improving the applicability of the device, and meeting more production needs.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
