[0024] The working principle and advantages of the present invention: When the classification and impurity removal equipment for Chinese medicine processing is used, the working process is as follows: like Figure 1 As shown, the motor is started, so that the motor drives the shaft 5 to rotate, thereby causing the shaft 5 to drive the conical screen drum 7 to rotate through the bracket 6, and the Chinese medicinal materials are put into the feeding hopper 4, and then enter the conical screen drum 7. After screening by the conical screen drum 7, the soil particles, stone particles, debris and other impurities therein are screened out, and are discharged from the discharge port 9 through the guide plate 10. The screened Chinese medicinal materials enter the right side of the partition 8 through the discharge port 2 11 and fall from above the scattering mechanism.

[0025] The shaft 5 rotates while driving the incomplete gear 51 to rotate. Figure 4 As shown, the teeth on the incomplete gear 51 are alternately meshed with the teeth on the two vertical frames on the inner side of the frame 24, so that the frame 24 moves up and down alternately, and then the frame 24 synchronously drives the connecting rod 25 and the rack 32 thereon to move up and down. While the rack 32 moves up and down, it drives the gear 41 to rotate back and forth, so that the gear 41 synchronously drives the groove wheel 39 fixed to it to rotate back and forth, and then the groove wheel 39 drives other groove wheels to rotate back and forth through the belt 42, and the rotation directions of the two adjacent groove wheels 39 are opposite. When the groove wheel 39 rotates, the swing plate 40 on it rotates, so that the Chinese medicinal materials are dispersed by the action of each swing plate 40 when falling, avoiding accumulation during blowing and uneven wind reception, and when the swing plate 40 contacts the surface of the Chinese medicinal materials, dust and debris adhering to the surface of the Chinese medicinal materials can be wiped off, playing a cleaning role and improving the cleaning effect.

[0026] As described above, while the shaft 5 rotates, the fan 13 is driven to work through the pulley assembly 12, so that the fan 13 accelerates the air through the air inlet pipe 14 and blows it toward the falling Chinese medicinal materials from the air outlet 15, and then the Chinese medicinal materials are subjected to air separation, so that the scraps, dandruff, dust, hair roots, etc. are separated, so that the fine Chinese medicinal materials fall into the fine area and fall into the collection box 1 19 through the hopper 1 18, the scraps fall into the scrap area and fall into the collection box 2 21 through the hopper 2 20, the dandruff, hair roots, etc. fall into the skin root area and fall into the collection box 3 23 through the hopper 3 22, and the dust, etc. enter the duct 44 with the air flow and enter the filter assembly for discharge.

[0027] As described above, the frame 24 moves up and down alternately, driving the piston plate 27 to move up and down in the pump barrel 26 through the connecting rod 1 25, so that the piston plate 27 alternately compresses and sucks the space on its upper and lower sides. Since the conduction direction of the one-way valve 1 28 points to the inside of the pump barrel 26, and the conduction direction of the one-way valve 2 30 points to the nozzle 33, the piston plate 27 draws the water in the water tank into the pump barrel 26 through the water pipe 1 29, and then transports the water to the nozzle 33 through the water pipe 2 31, and is sprayed toward the root area by the nozzle 33, so that dandruff, hair roots, etc. are easy to settle, and the humidity in the air is increased, so that dust in the air is easy to gather, and the airflow blows away the dust on the surface of the Chinese medicinal materials, thereby improving the cleaning effect during screening.

[0028] like Figure 3 and Figure 5 As shown, the air in the purification box 2 enters the filter cartridge 45 through the conduit 44. After being filtered and purified by the filter cartridge 45, the air is discharged through the exhaust pipe 50. In this way, the dust contained in the air can be filtered and collected to prevent it from escaping into the working environment again. When the shaft 5 rotates, the turntable 34 is simultaneously driven to rotate, so that the turntable 34 drives the slide 36 and the connecting rod 2 37 to move up and down through the pin rod 35, so that the connecting rod 2 37 drives the cap 48 and the brush ring 49 to move up and down, so that the brush ring 49 cleans the inner wall of the filter cartridge 45 to avoid accumulation and blockage, and ensures the normal filtering of dust. In the process of the cap 48 moving up and down, it is acted upon by the twisted rod 46 to rotate back and forth, so that the brush ring 49 cleans the inner wall of the filter cartridge 45 more efficiently, and the cleaned dust falls into the collection box 4 38 for collection.

[0029] The entire device realizes the screening and air separation of Chinese medicinal materials, thereby classifying and screening out soil particles, stone particles, dust, dandruff, hair roots, sundries and broken leaves in the Chinese medicinal materials, improving the quality of Chinese medicinal materials preparation, saving time and labor, and improving screening efficiency.
