[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] A vertical tea conveyor, such as Figures 1-7 As shown, the system includes a support frame 1 and positioning plates 2 and 3 fixedly connected to the support frame 1. Conveying rollers 4 and 5 are fixedly connected between positioning plates 2 and 3, and are connected by a conveyor belt 6. Several limiting frames 7 are fixedly connected to the conveyor belt 6, and filter screens 8 are fixedly connected to the limiting frames 7. A motor 9 is fixedly connected to positioning plate 2, and the output shaft of motor 9 is fixedly connected to conveying roller 4. Screening components for removing broken leaves from the tea leaves are provided on conveying roller 4, positioning plates 2 and 3. When tea is being conveyed... After completing the previous processing step, the tea leaves will fall onto the limiting frame 7 at the bend of the conveyor belt 6. During the next feeding, the limiting frame 7 will move to the bend of the conveyor belt 6. At this time, the motor 9 will be turned on, and the motor 9 will drive the first conveyor roller 4 to rotate. Then, the second conveyor roller 5 will rotate through the conveyor belt 6. When the conveyor belt 6 moves, the tea leaves will be driven by the limiting frame 7 and the filter screen 8 to transport the tea leaves to the next processing equipment at a higher position. During the transportation of the tea leaves, the screening component will be driven to screen the tea leaves and remove broken leaves. In this way, the tea leaves can be prevented from accumulating on the bottom side of the conveyor belt 6 and broken leaves in the tea leaves can be removed.

[0025] like Figures 3-4As shown, the screening assembly includes positioning rod 10 and positioning rod 11 rotatably connected between positioning plate 12 and positioning plate 23, several spring telescopic rods 12 fixedly connected to positioning rod 10 and positioning rod 21 respectively, and a ball 13 fixedly connected to the telescopic end of the spring telescopic rod 12. Belt roller 14 is fixedly connected to conveyor roller 14 and positioning rod 10 respectively, and the two belt rollers 14 are connected by belt 15. Belt roller 26 is fixedly connected to positioning rod 10 and positioning rod 21 respectively, and the two belt roller 26 are connected by belt 27. Positioning plate 12 and positioning plate 23 are provided with anti-jamming devices to prevent broken leaves from getting stuck on the filter screen 8. During tea transportation, motor 9 drives conveyor roller 14 to rotate, and then conveyor roller 14 drives belt roller 14 to rotate. When belt roller 14 rotates, belt roller 26 rotates through belt 15. The positioning rod 10 rotates, and the belt roller 16 on the same side also rotates when the positioning rod 10 rotates. Then, the belt roller 17 drives the other belt roller 16 to rotate, which in turn drives the positioning rod 11 to rotate. When the positioning rod 10 and the positioning rod 11 rotate, the spring telescopic rod 12 and the ball 13 also rotate. When the ball 13 rotates, it will hit the conveyor belt 6. At this time, the tea leaves are vibrated, and broken leaves are shaken out. Since the conveyor belt 6 is inclined, the broken leaves will fall to the ground through the filter screen 8 due to gravity. At this time, the spring telescopic rod 12 is in the telescopic state. Then, when the ball 13 no longer contacts the conveyor belt 6 as the spring telescopic rod 12 rotates, the spring telescopic rod 12 resets and prepares for the next impact. This process is repeated to remove broken leaves. When broken leaves are stuck on the filter screen 8, the anti-jamming device can shake the broken leaves off.

[0026] like Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, the anti-jamming component includes several positioning posts 18 fixedly connected to positioning plate 12 and positioning plate 23 respectively, bearings 19 rotatably connected to the positioning posts 18, and impact rods 20 fixedly connected to the bearings 19. The impact rods 20 are symmetrically arranged on opposite sides. When the limiting frame 7 moves with the conveyor belt 6, the limiting frame 7 will contact the impact rods 20 and push the impact rods 20. Then the impact rods 20 will start to rotate with the bearings 19 and impact the filter screen 8. Then they will be pushed by the next limiting frame 7 to impact the next filter screen 8. This process can be repeated to shake off the broken leaves stuck on the filter screen 8.

[0027] like Figures 4-6As shown, several positioning posts 18 are fixedly connected to connecting rods 21, and several connecting rods 21 are fixedly connected to stop rods 22. Several connecting rods 21 on opposite sides are symmetrically arranged. The stop rods 22 have elastic deformation capability. Before the impact rod 20 rotates and contacts the filter screen 8, it will first contact the stop rod 22. Then the stop rod 22 is deformed by the pressure of the impact rod 20. At this time, the impact rod 20 passes through the stop rod 22 and impacts the filter screen 8. The stop rod 22 returns to its original position. When the next limiting frame 7 has not yet contacted the impact rod 20, the impact rod 20 will rotate in the opposite direction due to gravity and contact the stop rod 22, and be blocked by the stop rod 22. This can prevent the impact rod 20 from missing the limiting frame 7.

[0028] like Figure 1 , Figure 4 As shown, baffles 23 are fixedly connected to the upper side of positioning plate 12 and positioning plate 23 to prevent tea leaves from falling to the ground when the ball 13 hits the conveyor belt 6.

[0029] like Figure 1 , Figure 4 As shown, a protective cover 24 is fixedly connected to the positioning plate 2 3 to protect belt 1 15 and belt 2 17, so as to prevent belt 1 15 and belt 2 17 from injuring people.

[0030] like Figure 1 , Figure 7 As shown, the limiting frame 7 is arc-shaped to prevent the tea leaves from falling to the ground when the ball 13 hits the conveyor belt 6.

[0031] Working principle: When tea leaves are to be conveyed, the tea leaves that have completed the previous processing step will fall onto the limiting frame 7 at the bend of the conveyor belt 6. When the next material is discharged, the limiting frame 7 will just move to the bend of the conveyor belt 6. At this time, the motor 9 will be turned on, and the motor 9 will drive the first conveyor roller 4 to rotate. Then, the second conveyor roller 5 will rotate through the conveyor belt 6. When the conveyor belt 6 moves, the tea leaves will be driven by the limiting frame 7 and the filter screen 8, and will be conveyed to the next processing equipment at a higher position.

[0032] During tea transportation, motor 9 drives conveyor roller 4 to rotate, which in turn drives belt roller 14 to rotate. As belt roller 14 rotates, belt roller 2 16 rotates via belt 15, causing positioning rod 10 to rotate. Simultaneously, as positioning rod 10 rotates, belt roller 2 16 on the same side also rotates, driving another belt roller 2 16 via belt 2 17, which in turn drives positioning rod 2 11. When positioning rod 10 and positioning rod 2 11 rotate, spring telescopic rod 12 and impact ball 13 also rotate. When impact ball 13 rotates, it strikes conveyor belt 6, causing the tea leaves to vibrate and break off pieces. Because conveyor belt 6 is inclined, the broken pieces fall through the filter screen 8 due to gravity. After falling to the ground, the spring telescopic rod 12 is in the telescopic state. Then, the impact ball 13 rotates with the spring telescopic rod 12 and no longer contacts the conveyor belt 6. At this time, the spring telescopic rod 12 resets and prepares for the next impact. This process repeats to remove broken leaves. When the limiting frame 7 moves with the conveyor belt 6, the limiting frame 7 will contact the impact rod 20 and push the impact rod 20. Then, the impact rod 20 starts to rotate with the bearing 19 and impacts the filter screen 8. Then, it is pushed by the next limiting frame 7 to impact the next filter screen 8. This process repeats to shake off the broken leaves stuck on the filter screen 8. In this way, the broken leaves wrapped inside the tea leaves can be removed during tea transportation. The impact rod 20 can also shake off the broken leaves stuck on the filter screen 8, improving processing efficiency.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
