Fans 35 are arranged at the two ends of the rotating shaft 34. The driving assembly 60 is arranged on the separating box 30 and is used for driving the rotating shaft 34 to rotate. The driving assembly 60 drives the rotating shaft 34 to rotate, which drives the fans 35 to rotate. One of the fans 35 blows external air into the separating box 30. The other fan 35 blows the air in the separating box 30 outward. The air flow carries away a part of tea hairs in the falling tea. The tea hairs are carried to the filter screen 41 by the air flow and are blocked by the filter screen 41, so that the tea hairs are prevented from floating out of the separating box 30 and mixing into the external air, thereby preventing the respiratory health of nearby workers from being threatened. After the tea is added, the cover plate 32 is closed, so that the upper part of the inlet hopper 31 is closed, and the tea hairs and dust raised during the screening of the screening assembly 20 are prevented from floating out of the inlet hopper 31. During the screening of the screening assembly 20, the fans 35 continuously rotate, and the filter screen 41 continuously filters the tea hairs and dust. After the screening is completed, the driving assembly 60 is closed, and the collecting assembly 50 collects the tea hairs and dust.

[0031] When being set, the screening assembly 20 comprises a screening frame 21 vertically slidingly arranged in the screening box 10, two screening boxes 22 are vertically spaced in the screening frame 21, and a plurality of screening holes 23 are formed in the screening boxes 22, the screening holes 23 in the upper screening box 22 are larger than the screening holes 23 in the lower screening box 22, tea leaves fall on the screening boxes 22, the screening boxes 22 reciprocate up and down to shake the tea leaves, larger tea leaves are retained in the upper screening box 22, smaller tea leaves fall into the lower screening box 22 through the screening holes 23, and tea dregs or impurities fall into the bottom of the screening box 22 through the screening holes 23 of the lower screening box 22. The rotating disc 24 is rotatably arranged in the screening box 10, the rotating disc 24 is provided with a clamping column 25 near the edge of the disc surface, the connecting block 26 is arranged on the side of the screening frame 21 close to the rotating disc 24, the strip-shaped hole 27 is horizontally arranged on the connecting block 26, the clamping column 25 is slidingly connected with the strip-shaped hole 27, the rotating unit 70 is arranged on the screening box 10 to rotate the rotating disc 24, since the connecting block 26 is connected with the screening frame 21, the connecting block 26 can only move up and down, the rotating unit 70 drives the rotating disc 24 to rotate to drive the clamping column 25 to rotate, the clamping column 25 reciprocally slides in the strip-shaped hole 27 to drive the connecting block 26 to move up and down, and the screening frame 21 and the screening boxes 22 reciprocally move up and down. Two sliding grooves 11 are vertically formed in the opposite inner walls of the screening box 10, the sliding block is slidingly arranged in the sliding groove 11, the screening frame 21 is connected with the four sliding blocks to ensure the stability of the sliding of the screening frame 21. After the screening is completed, the worker opens the door of the screening box 10 to take out the tea leaves on the screening boxes 22, and then cleans the impurities and tea dregs in the bottom of the screening box 10.
[0032] The rotating hole is horizontally formed in the screening box 10, the rotating hole is concentric with the rotating disc 24, the rotating unit 70 comprises the rotating shaft 71 rotatably arranged in the rotating hole, one end of the rotating shaft 71 is connected with the rotating disc 24, the other end of the rotating shaft 71 is provided with the fourth pulley 72, the third pulley 73 is arranged on the output shaft of the driving motor 62, the fourth pulley 72 and the third pulley 73 are connected through the second transmission belt 74, the driving motor 62 drives the fourth pulley 72 to rotate to drive the third pulley 73 to rotate, the rotating shaft 71 and the rotating disc 24 to rotate. Two functions are realized through one driving motor 62, the efficiency of the equipment is improved, and the cost of the equipment is reduced. The diameter of the first pulley 63 is larger than the diameter of the second pulley 64, the diameter of the fourth pulley 72 is larger than the diameter of the third pulley 73, and the diameter of the first pulley 63 is larger than the diameter of the third pulley 73.
[0033] Specifically, the installation pipe 40 is provided with a through slot 42 on the lower pipe body near the side of the filter screen 41 close to the separation box 30, the collection assembly 50 comprises an installation box 51 arranged at the through slot 42, an opening 52 is arranged on one side of the installation box 51, and a collection box 53 is slidably arranged in the installation box 51 and slidably matched with the opening 52. A handle 54 is arranged on the side wall of the collection box 53. After the fan 35 stops rotating, the suction force is lost, so that the tea hairs on the filter screen 41 fall off and fall into the collection box 53 through the through slot 42. The installation pipe 40 can also be knocked to shake off the tea hairs attached to the filter screen 41. Then, the handle 54 is pulled to pull the collection box 53, and the collection box 53 is slid out of the opening 52, so that the tea hairs in the collection box 53 can be easily cleaned.
[0034] The use principle of the tea separation device with the screening function in the embodiment is as follows: tea is poured into the hopper, and then the tea enters the separation box 30. After the driving motor 62 is started, the motor drives the first pulley 63 to rotate, and then drives the second pulley 64, the rotating shaft 34 and the fan 35 to rotate together. This process makes one fan 35 blow external air into the separation box 30, and the other fan 35 blows the air in the box out. The air flow carries away part of the tea hairs in the falling tea, and the tea hairs flow to the filter screen 41 with the air flow and are blocked by the filter screen 41, so that the tea hairs are prevented from floating out of the separation box 30 and mixing into the external air, thereby avoiding the threat to the respiratory health of the nearby workers. After the tea is added, the cover plate 32 is closed, and the driving motor 62 drives the fourth pulley 72 to rotate, and then drives the third pulley 73, the rotating shaft 71, the rotating disc 24 and the clamping column 25 to rotate. The clamping column 25 reciprocally slides in the strip-shaped hole 27, drives the connecting block 26 to move up and down, and drives the screening frame 21 and the screening box 22 to reciprocally move up and down, so as to shake the tea. The larger tea is left in the upper screening box 22, and the smaller tea falls into the lower screening box 22 through the screening hole 23. The tea dregs or impurities fall on the bottom through the screening hole 23 of the lower screening box 22. While the screening assembly 20 is screening, the fan 35 continuously rotates, and the filter screen 41 continues to filter the tea hairs and dust. After the screening is completed, the driving motor 62 is closed, and the door of the screening box 10 is opened, so that the tea on the screening box 22 is taken out. Then, the impurities and tea dregs on the bottom of the screening box 10 are cleaned, and the collection box 53 is taken out, so that the tea hairs and dust in the collection box 53 are cleaned. The above is only the preferred embodiment of the present application, and the protection scope of the present application is not limited to the above embodiment. Any technical solution falling within the idea of the present application belongs to the protection scope of the present application.
