An air inlet 3 is penetrated and opened on one side of the pneumatic separation box 1 close to the blower 2, and the size of the air inlet 3 matches the air outlet size of the blower 2 to maximize the wind power utilization rate, and an air exhaust port 4 is penetrated and opened on the side of the pneumatic separation box 1 away from the air inlet 3.

[0027] Reference Figure 1 , Figure 2 and Figure 5The material control mechanism includes a first rotating shaft 5 rotatably connected to the air separation box 1, at least one end of the first rotating shaft 5 extends to the outside of the air separation box 1, a wind wheel 6 is fixedly connected to the first rotating shaft 5, and the wind wheel 6 is at least partially close to the air inlet 3. The end of the first rotating shaft 5 is fixedly connected to a driving wheel 11, and the driving wheel 11 is located outside the air separation box 1. The fan blades outside the wind wheel 6 are spiral-shaped, and only a part of the wind wheel 6 extends to the air inlet 3, so that the wind wheel 6 will not affect the air separation of Chinese herbal medicines.

[0028] Reference Figure 1-Figure 4 The material control mechanism also includes a second rotating shaft 9 rotatably connected to the discharge bin 7, at least one end of the second rotating shaft 9 extends to the outside of the discharge bin 7, a feeding wheel 10 is fixedly connected to the second rotating shaft 9, the outside of the feeding wheel 10 is in contact with the inner wall of the discharge bin 7, and a driven wheel 12 is fixedly connected to the end of the second rotating shaft 9. The driven wheel 12 is located outside the discharge bin 7, and a belt 13 is sleeved between the driven wheel 12 and the driving wheel 11. The outside of the feeding wheel 10 is a plurality of baffles, which are used to temporarily store Chinese herbal medicines. When the baffles in the corresponding direction rotate to the bottom, the Chinese herbal medicines will fall downward. The transmission mode between the belt 13 and the driving wheel 11 and the driven wheel 12 can also be replaced with other transmission modes, such as chains and sprockets, as long as the transmission can be achieved.

[0029] Reference Figure 2-Figure 3 The cross-section of the diverter rod 8 is an isosceles triangle, and the diverter rod 8 is located directly above the unloading wheel 10. When a large amount of Chinese herbal medicines are placed in the discharge bin 7, they will be diverted to both sides by the diverter rod 8, which can effectively prevent the Chinese herbal medicines from piling up above the unloading wheel 10, thereby reducing the resistance encountered by the unloading wheel 10 during rotation.

[0030] Reference Figure 2 Two groups of discharge ports 14 are provided at the bottom of the air separation box 1.

The wind blown by the blower 2 will first drive the wind wheel 6 to rotate, and drive the second rotating shaft 9 to rotate through the driving wheel 11 and the belt 13, thereby driving the unloading wheel 10 to rotate, so that the Chinese herbal medicine slices are evenly dropped into the air selection box 1 through the unloading wheel 10 for air selection (it should be explained that the wind force generated by the blower 2 during air selection is actually sufficient to drive the wind wheel 6 to rotate, and overcome the resistance of the unloading wheel 10 to some Chinese herbal medicine slices). Before sorting, the staff will control the air outlet speed of the blower 2 according to the weight of the Chinese herbal medicine slices. Different air outlet speeds of the blower 2 will drive the wind wheel 6 to have different rotation speeds. , thereby controlling the feeding speed of the Chinese herbal medicine slices, while ensuring the air selection effect of the Chinese herbal medicine slices, maximizing the air selection efficiency of the Chinese herbal medicine slices, and making the operation simpler; during the air selection process of the Chinese herbal medicine slices, the finished products will fall onto the buffer plate 16 below, and the internal impurities, dust, etc. will be blown out by the wind through the exhaust port 4, among which the incomplete Chinese herbal medicine slices will be blown a distance and fall onto another buffer plate 16; when the Chinese herbal medicine slices fall onto the buffer plate 16, the buffer plate 16 vibrates under the action of the spring 17, and the Chinese herbal medicine slices are slowly transmitted downward on the buffer plate 16 until they fall onto the slope 15, and are finally discharged through the corresponding discharge port 14.
