Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine processing, in particular to a grinding device for traditional Chinese medicine processing with a discharge multi-stage screening function. Background Art

[0002] There are various forms of application of Chinese herbal medicine. It can be made into Chinese herbal decoction by directly decocting Chinese medicinal materials in water, and can also be made into powder by grinding Chinese medicinal materials into powder, as well as ointments, tablets, granules and injections. Grinding Chinese medicinal materials and reprocessing them is beneficial to the effective absorption by the human body. In the process of grinding Chinese medicinal materials, due to the complexity of the ingredients of Chinese medicinal materials, there will be materials that cannot be completely ground after grinding. These materials cannot be used for medicinal purposes and need to be screened out. Therefore, it is necessary to screen the Chinese medicinal materials after grinding. In this way, grinding and screening equipment for processing Chinese medicinal materials is needed.

[0003] However, the existing grinding and screening devices for processing Chinese medicinal materials still have certain defects when used;

[0004] For example, a grinding and screening integrated Chinese medicine processing device proposed in application number CN201911190472.7 includes a processing box, the processing box includes a grinding box and a screening box, a filter is installed between the grinding box and the screening box, and a material dividing device, a grinding device and a rolling device are respectively arranged inside the grinding box. In the grinding and screening integrated Chinese medicine processing device, a filter is arranged in the processing box to divide the processing box into a grinding box and a screening box, so that grinding and screening are carried out in the same process, simplifying the process steps and improving work efficiency. The electric push rod pushes the grinding block to reciprocate up and down, and at the same time, the connecting shaft drives the electric push rod to rotate to realize the mechanized grinding of Chinese medicine. The rotating shaft is driven to rotate by the working motor to realize the synchronous rotation of the two elliptical teeth, and the two elliptical teeth slide on the fixed pulley. The screening box is shaken up and down by the different heights of the two elliptical teeth to complete the mechanized screening work. In the actual use process, there are still the following problems:

[0005] The device grinds the Chinese medicinal materials directly without pre-treatment before grinding, so that the Chinese medicinal materials with a large volume cannot normally enter the grinding structure, which is more likely to cause the grinding structure to be blocked and stuck, thereby reducing the grinding effect;

[0006] When the device screens the Chinese medicinal materials after grinding, the remaining Chinese medicinal materials on the screen are not completely ground, and the device directly discharges these Chinese medicinal materials without grinding them again, further reducing the grinding effect;

[0007] In the process of screening the ground Chinese medicinal materials through the screen, the ground Chinese medicinal materials are easily accumulated on the surface of the screen, which may cause the screen to be blocked, thereby affecting the screening efficiency and effect.

[0008] In view of this, we conducted in-depth research on the above issues, which led to the present case.

[0009] In view of the above problems, an innovative design was carried out based on the original grinding device for traditional Chinese medicine processing with the function of multi-stage screening of discharge. Summary of the invention
