[0030] During operation, tea leaves are first poured into the top of the transmission sieve plate 20, and then the servo motor 12 on the side of the first fixed block 10 is started, driving the first transmission rod 13 to rotate. When the first transmission rod 13 rotates, it drives the first pulley 14 to rotate synchronously, and the first pulley 14 drives the transmission belt 15 on the side of the second fixed block 11 to rotate.

At the same time, the other end of the transmission sieve plate 20 is driven by the second transmission rod 17 to rotate and transport tea leaves. The baffle 31 can block the tea leaves.

[0033] Furthermore, a fourth fixing block 21 is also provided at the front and rear ends of the left side end of the first fixing block 10 and the right side end of the second fixing block 11. The first fixing block 10 and the second fixing block 11 are also welded to one end of the fourth fixing block 21.

[0034] When the first fixed block 10 and the second fixed block 11 vibrate during operation, they drive the guide rod 22 to move up and down along the outside of the guide rod 22 inside the fifth fixed block 23, which in turn causes the return spring 24 to be stretched and compressed.

[0035] Furthermore, the outer side of the fifth fixing block 23 is welded to the inner side of the fixing frame 25 near the upper position. Support legs 26 are also provided on the left and right sides of the bottom end of the fixing frame 25, and the bottom end of the fixing frame 25 is welded to the top end of the support leg 26, and the bottom end of the support leg 26 is welded to the top end of the base 1.

[0036] During operation, the cooperation of the fixing frame 25 and the support leg 26 can support and fix the position of the fifth fixing block 23.

[0037] Furthermore, the bottom ends of the first fixing block 10 and the second fixing block 11 are also welded to the top end of the sixth fixing block 27, the middle position of the bottom end of the sixth fixing block 27 is welded to the top end of the vibration motor 28, and the bottom end of the vibration motor 28 is welded to the middle position of the top end of the fixing frame 25.

[0038] During operation, the vibration motor 28 at the top of the fixed frame 25 is started, which drives the sixth fixed block 27 to vibrate. The sixth fixed block 27 also drives the first fixed block 10 and the second fixed block 11 to vibrate simultaneously, thereby vibrating and screening the tea leaves above the transmission screening plate 20.

[0039] Furthermore, a first screening plate 29 is provided below the transmission screening plate 20 near the rear position, and the bottom end of the first screening plate 29 is welded to the top end of the base 1. A second screening plate 30 is provided below the first screening plate 29 near the rear position, and the bottom end of the second screening plate 30 is welded to the top end of the base 1.

[0040] During operation, the transmission sieve plate 20 drives the tea leaves that have been sieved once to move and fall to the top of the first sieve plate 29. At the same time, it continues to move downward along the top of the first sieve plate 29 and falls to the top of the second sieve plate 30 and continues to move downward. During the movement, the first sieve plate 29 and the second sieve plate 30 simultaneously sieve and remove stems from the tea leaves again.

[0041] Working principle: When it is necessary to remove stems from tea leaves, the tea leaves are first poured into the top of the transmission sieve plate 20. Then, the servo motor 12 on the side of the first fixed block 10 is started, driving the first transmission rod 13 to rotate. When the first transmission rod 13 rotates, it drives the first pulley 14 to rotate synchronously. The first pulley 14 drives the transmission belt 15 on the side of the second fixed block 11 to rotate. At the same time, when the first transmission rod 13 rotates, it drives the transmission sieve plate 20 to rotate synchronously. When the transmission belt 15 rotates, it drives the second pulley 16 and the second transmission rod 17 to rotate simultaneously. The second transmission rod 17 drives the rotating block 18 to rotate along the inside of the third fixed block 19. At the same time, the other end of the transmission sieve plate 20 is driven by the second transmission rod 17 to rotate and transport the tea leaves. Simultaneously, the vibration motor at the top of the fixed frame 25 is started. The motor 28 drives the sixth fixed block 27 to vibrate, and the sixth fixed block 27 drives the first fixed block 10 and the second fixed block 11 to vibrate simultaneously, thereby vibrating and screening the tea leaves above the transmission sieve plate 20. At the same time, when the first fixed block 10 and the second fixed block 11 vibrate, they drive the guide rod 22 to move up and down along the outside of the guide rod 22 inside the fifth fixed block 23. This will cause the return spring 24 to be stretched and compressed. Then the transmission sieve plate 20 drives the tea leaves that have been screened once to move and fall to the top of the first sieve plate 29. At the same time, the tea leaves continue to move down along the top of the first sieve plate 29 and fall to the top of the second sieve plate 30 and continue to move down. During the movement, the first sieve plate 29 and the second sieve plate 30 simultaneously screen and remove stems from the tea leaves again.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
