Light impurities are carried by the airflow to the debris collection box 20, and the finished medicinal materials fall into the discharge port 7 through the buffer material chamber 15; the collection mechanism 3 receives the finished products through the guide slope 313 and the collection bucket 32, thus completing the air separation process.

[0041] The feeding component 8 precisely controls the speed and adjusts the angle to ensure that the material enters the air separator 4 evenly; the multi-level inclined planes and partitions in the air separator 4 work with the airflow to achieve multi-level separation of impurities; the lifting and moving component 9 flexibly adjusts the feeding position and height to adapt to different production layouts; the collecting mechanism 3 efficiently gathers and stores finished products.

[0042] This utility model features a rational overall design. The air separation mechanism 1 utilizes a guide plate 10 and spacer baffles 11 to create an orderly material flow channel, extending the air separation contact time. The first baffle 13 and multi-stage inclined surfaces, combined with the directional air curtain of the air supply component 5, deeply remove light impurities and fine debris, solving the problem of impurity residue in traditional air separation. The lifting feeding mechanism 2 uses a conveyor belt 81 and adjustable guide plate 84 to achieve quantitative, directional, and angle-adaptive feeding. The scissor lift frame 91 and horizontal fine-tuning component adapt to the needs of multiple heights and workstations, solving the problems of low efficiency and poor compatibility of manual feeding. The collection mechanism 3 uses a guide inclined surface 313 and a detachable collection bucket 32 ​​to achieve automatic collection and convenient cleaning of finished products, avoiding material residue and secondary pollution. The overall solution, through precise feeding, graded air separation, and efficient collection, solves the problems of low efficiency, poor accuracy, and weak compatibility in traditional Chinese medicine air separation, achieving standardization and automation of Chinese medicine pretreatment.
