Description

Technical Field

[0002] The medicinal material air sorting machine is mainly suitable for the air sorting and grading of Chinese medicinal material raw materials, Chinese medicinal pieces, seed-type medicinal materials, medicinal material semi-finished products, and medicinal material finished products. The working principle of the medicinal material air sorting machine is as follows: the airflow generated by the fan enters the air sorting mechanism, and the medicinal materials also enter the air sorting mechanism through the conveying mechanism and are driven by the airflow, and finally graded in the air sorting mechanism. However, the medicinal materials to be processed often carry various small debris. During the process of grading the medicinal materials, the debris will still be wrapped in the graded medicinal materials, which will then affect the quality of air sorting. Utility Model Content

The filter panels are used to continuously guide the medicinal materials falling into the transition tube downward. A slag collection drawer is inserted into the bottom of the impurity removal box, and the slag collection drawer runs through the side wall of the transition tube.

[0008] The unloading end of the second feeding mechanism is located just above the feeding port of the air separation mechanism.

[0009] Furthermore, the transition tube is a square structure, and the debris removal boxes are alternately arranged on two pairs of side walls of the transition tube.
