Description

Technical Field

[0001] This utility model relates to the field of Chinese medicinal material production and processing technology, specifically a multi-stage screening mechanism for impurities in Chinese medicinal materials. Background Technology

[0002] Traditional Chinese medicine (TCM) is mainly composed of plant-based, animal-based, and mineral-based medicines. Because plant-based medicines make up the majority of TCM, it is also called Chinese medicinal materials. Chinese medicinal materials are unique medicines used by TCM for the prevention and treatment of diseases, and are an important feature that distinguishes TCM from other medical systems. In the processing of Chinese medicinal materials, in order to ensure quality, most of them need to be screened so that larger and smaller medicinal materials can be selected, thereby improving the quality of the medicinal materials.

[0003] Publication No. CN218048830U discloses a multi-stage vibrating Chinese medicinal herb screening device. By setting up a primary screening mechanism, medicinal herbs are added through the inlet and fall onto a transmission mesh belt. A drive motor drives a rotating roller to rotate, which in turn drives the transmission mesh belt to rotate. This simultaneously conveys the medicinal herbs and filters out sand and dust from the mesh belt, collecting them in a receiving trough. A secondary screening mechanism is then set up. The drive motor drives a rotating cam to rotate through the transmission belt, which, in conjunction with a spring, causes the screening mesh plate to reciprocate vertically, performing a secondary screening of the primary-screened herbs. This removes withered branches and leaves, enhancing the functionality of the screening device and meeting the requirements of multi-stage screening. However, this patent still has the following problems in practical use:

[0004] Although this multi-stage vibrating Chinese medicinal herb screening device can perform multi-stage screening of Chinese medicinal herbs by setting up a primary screening mechanism and a secondary screening mechanism, and can screen out the sand and dust contained in the Chinese medicinal herbs through the mesh of the transmission belt and collect them in the receiving trough, it cannot distinguish the size of the impurities and the size of the medicinal herbs in each stage, thereby reducing the practicality of the medicinal herbs.
