[0022] Please refer to Figure 1-5As shown, the utility model provides a wind separator for tea processing, wherein a plurality of fans 5 are arranged on one side wall of a wind selection channel 1, a first baffle 6 is rotatably arranged in the wind selection channel 1 and above the fan 5, an edge of the first baffle 6 is rotatably arranged on the rear wall of the wind selection channel 1 through a rotating shaft 7, and then one end of the rotating shaft 7 passes through the outer wall behind the side wall of the wind selection channel 1 and is fixedly sleeved and connected with a gear 8, and at the same time, a guide groove 11 is fixedly arranged on the outer wall of the wind selection channel 1, a sliding block 12 is slidably connected in the guide groove 11, and then a bar tooth 9 meshingly connected with the gear 8 is fixedly arranged on the bottom wall of the sliding block 12, and at the same time, a plurality of bar teeth 9 are fixedly connected by a connecting rod 10, and one end of a connecting rod 10 at the end is connected with a servo electric push rod 13 fixedly arranged on the outer wall of the wind selection channel 1, Then, a feed box 14 connected to the air selection path 1 is arranged at one end of the air selection path 1, a fan blade 16 is arranged on the side wall of the feed box 14, and then a feed port 15 is arranged on the top wall of the feed box 14, and at the same time, a second baffle 17 is slidably arranged in the feed box 14, a slide groove is arranged on the bottom wall of the feed box 14, a screw rod 18 is rotatably connected in the slide groove, a slider 19 is threadedly sleeved on the outer side of the screw rod 18, and the upper surface of the slider 19 is connected to the bottom wall of the second baffle 17, and a through hole 20 matching the second baffle 17 is arranged on the front wall of the feed box 14, so that the through hole 20 can completely pass through the through hole 20, and at the same time, one end of the screw rod 18 passes through the side wall of the second baffle 17, and the outer side of one end of the screw rod 18 and the end located on the outside of the feed box 14 is transmission-connected to the power output end of the servo motor through a transmission belt;

[0023] When shielding the fan 5 and the fan blades 16, the free end of the servo electric push rod 13 drives the tooth 9 to move through the connecting rod 10, thereby realizing the meshing rotation of the gear 8, and then drives the rotating shaft 7 and the first baffle 6 to rotate through the gear 8. Since the rotating shaft 7 is arranged at the edge of the first baffle 6, the first baffle 6 will intermittently shield the fan 5 when rotating along the rotating shaft 7. At the same time, the servo motor drives the screw rod 18 to rotate through the transmission belt, so that the slider 19 threadedly connected to the outside of the screw rod 18 drives the second baffle 17 to move back and forth in the feed box 14. The fan 5 and the fan blades 16 are intermittently blocked. When in use, the blocking time of the first baffle 6 on the fan 5 and the blocking time of the second baffle 17 on the fan blades 16 are staggered, so that the wind force of the fan 5 and the fan blades 16 can be staggered to blow the tea leaves, so that the fan blades 16 blow the tea leaves into the air selection path 1 and drop them onto the upper surface of the screening net 3 for screening by the vibration motor. The fan 5 then blows the tea leaves out of the air selection path 1, avoiding the fan 5 and the fan blades 16 from blowing the tea leaves at the same time, and blowing the unscreened tea leaves directly out of the air selection path 1, thereby affecting the quality of the tea leaves.

[0024] As a further implementation of this embodiment, Figure 1-5As shown, a plurality of blocking plates 2 of different heights are also arranged in the air selection channel 1, and the blocking plates 2 are used to separate the tea leaves of different sizes. Then, a screening net 3 is arranged in the air selection channel 1 and below the fan 5. A waste discharge port 4 is provided in the bottom wall of the air selection channel 1, and a plurality of discharge ports 21 are provided in the front wall of the air selection channel 1.

[0025] Specific working principle:

[0026] When in use, tea leaves are put into the feed port 15, and then blown into the air selection path 1 by the fan blades 16. At this time, the free end of the servo electric push rod 13 drives the tooth 9 to move through the connecting rod 10, thereby realizing the meshing rotation of the gear 8, and then drives the rotating shaft 7 and the first baffle 6 to rotate through the gear 8. Since the rotating shaft 7 is arranged at the edge of the first baffle 6, the first baffle 6 will intermittently block the fan 5 when rotating along the rotating shaft 7. At the same time, the servo motor drives the screw rod 18 to rotate through the transmission belt, so that the slider 19 threadedly connected to the outside of the screw rod 18 drives the second baffle 17 to move back and forth in the feed box 14, thereby realizing the meshing rotation of the fan blades 1 6 intermittent blocking, when in use, the blocking time of the first baffle 6 on the fan 5 and the blocking time of the second baffle 17 on the fan blades 16 are staggered, so that the wind force of the fan 5 and the fan blades 16 can be staggered to blow the tea leaves, so that the fan blades 16 blow the tea leaves into the air selection path 1 and drop them onto the upper surface of the screening net 3 for screening by the vibration motor, and then the fan 5 blows the tea leaves out of the air selection path 1, avoiding the fan 5 and the fan blades 16 blowing the tea leaves at the same time, and blowing the unscreened tea leaves directly out of the air selection path 1, thereby affecting the quality of the tea leaves. The fan blades 16 first discharge the tea leaves, and finally the residues and impurities from the waste discharge port 4, and the screened tea leaves are discharged from the discharge port 21.
