[0018] The present invention adopts the above technical solution to bring the following beneficial effects:

[0019] 1. This Chinese medicinal material combing equipment ensures that the screening net rotates stably and efficiently through the precise transmission mechanism of the driving gear and the ring driven by the driving motor, realizes high-precision screening according to the slight differences in the sizes of Chinese medicinal materials, gets rid of the dependence on manual screening, greatly reduces labor costs and time consumption, and delivers materials of uniform quality to subsequent processing links, significantly improving the overall processing efficiency and product standardization. The elastic rod continuously plays a dynamic collision role in the screening process, effectively breaking the adhesion between Chinese medicinal materials, and maintaining the loose and uniform distribution of materials on the screening net, fundamentally ensuring the smoothness and accuracy of the screening process, consolidating the efficient screening performance of the equipment, and laying a solid foundation for the refined processing of Chinese medicinal materials.

[0020] 2. This Chinese medicinal material combing equipment, through the impurity removal system constructed by the fan, connecting pipe and air outlet pipe, generates airflow to accurately penetrate the screening net, deeply removes dust, debris and other impurities on the surface and in the gaps of the Chinese medicinal materials. Driven by the airflow, the impurities smoothly pass through the screening net and the filter plate, gather in the feed trough and are discharged to the impurity discharge plate through the impurity discharge port. This not only greatly reduces the heavy labor of manual impurity removal, but also significantly improves the purity and quality stability of Chinese medicinal materials. At the same time, the airflow can also clean the screening net to avoid clogging of the screening net.

[0021] 3. In this Chinese medicinal material combing equipment, the circular rotation drives the first driven gear to rotate, thereby driving the first rotating rod and the eccentric wheel to operate stably. The periodic movement of the eccentric wheel squeezes the spring, prompting the movable plate to drive the knocking rod to knock the elastic plate. The vibration wave is transmitted to the screening net, which effectively resists the risk of agglomeration and clogging of Chinese medicinal materials during the screening process, ensures the continuous screening and impurity removal of materials on the screening net, avoids clogging of the screening net, and affects the screening and impurity removal effects.

[0022] 4. This Chinese medicinal material combing equipment, through the ingenious layout of the feeding plate, main partition plate and inclined plate, constructs an efficient diversion path based on the inherent differences in the size of Chinese medicinal materials, realizes the initial orderly classification of materials, and creates favorable conditions for subsequent differentiated processing based on size characteristics.

[0023] 5. This Chinese medicinal material combing equipment can adjust the distance between the conveyor belt and the adjusting block by setting an adjusting bolt, so as to facilitate combing according to the thickness of the Chinese medicinal materials, and then further screen and comb the Chinese medicinal materials of different thicknesses through the guide plate and the partition plate, without the need for subsequent manual combing, thereby improving work efficiency.
