The lower ends of the two movable rods 24 are fixed with the same cleaning brush 26, and the upper ends of the two movable rods 24 are fixed with the same movable plate 23. The two movable rods 24 are both provided with springs 25. The upper end of the spring 25 is connected to the lower end of the movable plate 23, and the lower end of the spring 25 is connected to the top of the air outlet pipe 20. One end of the second traction rope 22 away from the second reel 18 is fixedly connected to the lower end of the movable plate 23. When the second traction rope 22 is relaxed, the elastic force of the spring 25 acts on the movable plate 23, so that the movable plate 23 can move up and reset.

[0038] The vibration mechanism includes a mounting frame 29 arranged inside the air outlet duct 20, the upper and lower ends of the mounting frame 29 are respectively fixedly connected to the inner top wall and the inner bottom wall of the air outlet duct 20, and two vibration members are arranged on the left side wall of the mounting frame 29, and the vibration member includes a knocking block 31 which is arranged through the mounting frame 29, and the knocking block 31 is slidably connected to the mounting frame 29, and a first magnetic block 33 is fixed to the right end of the knocking block 31, and a first tension spring 32 is sleeved on the knocking block 31, one end of the first tension spring 32 is connected to the mounting frame 29, and the other end of the first tension spring 32 is connected to the knocking block 31, and a second rotating shaft 35 is arranged through the right side wall of the mounting frame 29. The second rotating shaft 35 is rotatably connected to the mounting frame 29, a rotating plate 30 is fixed to the left end of the second rotating shaft 35, a third reel 34 is fixed to the right end of the second rotating shaft 35, a torsion spring 36 is sleeved on the second rotating shaft 35, one end of the torsion spring 36 is fixed to the right side wall of the mounting frame 29, and the other end of the torsion spring 36 is fixed to the side wall of the second rotating shaft 35, the torsion force of the torsion spring 36 can act on the second rotating shaft 35 to drive the second rotating shaft 35 to rotate, and a third traction rope 28 is fixed to the third reel 34, and one end of the third traction rope 28 away from the third reel 34 passes through the inner top wall of the air outlet duct 20 and is fixedly connected to the lower end of the movable plate 23.

[0039] When the present invention is used, the inlet fan 7 and the outlet fan 21 are started to form an airflow moving to the right above the interior of the box body 1, and the Chinese herbal medicine pieces to be sorted are added to the interior of the feed hopper 2. The Chinese herbal medicine pieces in the feed hopper 2 will enter the interior of the discharge chute 42, and the motor 5 is started to drive one of the discharge rollers 41 to rotate. The transmission effect of the two gears 6 can make the two discharge rollers 41 rotate synchronously, so that the Chinese herbal medicine pieces can be intermittently dropped in small amounts;

[0040] The Chinese herbal medicine pieces are sorted by airflow, and the qualified Chinese herbal medicine pieces fall into the collecting hopper 9, and the Chinese herbal medicine pieces fall into the collecting box 11 for collection by the collecting hopper 9, and the broken pieces fall into the discharging hopper 15 for discharging, while the lighter dust and debris move with the airflow to the air outlet pipe 20 and are adsorbed to the left surface of the filter screen 27;

[0041] When the collecting box 11 is full of Chinese medicine pieces, the Chinese medicine pieces are stopped from being discharged. Due to the increase in the overall weight of the collecting box 11, the second magnetic block 37 and the third magnetic block 39 are separated under the action of gravity, and then the collecting box 11 falls together with the placing frame 10. The first traction rope 14 can be used to pull the first reel 17 to rotate, and the first rotating shaft 19 can be used to drive the second reel 18 to rotate. The rotation of the second reel 18 can reel in the second traction rope 22, and the second traction rope 22 can be used to pull the movable plate 23 downward, and the movable rod 24 can be used to drive the cleaning brush 26 to move downward. The cleaning brush 26 can be used to brush off the dust and debris adhering to the filter screen 27, and the surface of the filter screen 27 is cleared. When the movable plate 23 moves downward, the third traction rope 28 can be loosened. Under the torsion force of the torsion spring 36, the second rotating shaft 35 can be driven to rotate, and the rotating plate 30 can be driven to rotate through the second rotating shaft 35. When the rotating plate 30 rotates to approach the first magnetic block 33, the first magnetic block 33 and the knocking block 31 can be moved to the right by utilizing the magnetic attraction, and the first tension spring 32 can be stretched. When the rotating plate 30 is away from the first magnetic block 33, the tension of the first tension spring 32 acts on the knocking block 31, which can drive the knocking block 31 to move left and knock the filter 27, so that the filter 27 can vibrate, and then the dust and debris adhering to the filter 27 can be more easily separated from the filter 27, thereby improving the cleaning effect of the filter 27. There is no need to manually clean the filter 27, which saves time and effort. Then the collection box 11 can be taken out and the Chinese herbal medicine slices can be unloaded.

When the cleaning brush 26 moves downward to clean the filter 27, the partition 43 will be driven to move downward. The partition 43 can be used to block and shield the left end of the air outlet duct 20, thereby effectively preventing dust and debris from entering the interior of the box body 1 during cleaning.
