Description

Technical Field

[0001] This utility model relates to the technical field of medicinal material processing equipment, and in particular to a multi-stage screening and grading device for Polygonatum sibiricum. Background Technology

[0002] Polygonatum is a perennial herb belonging to the genus Polygonatum in the family Asparagaceae. It is neutral in nature and sweet in taste, and enters the spleen, lung, and kidney meridians. It has the functions of replenishing qi and nourishing yin, strengthening the spleen and moistening the lungs, and benefiting the kidneys and replenishing essence. It is often used to treat symptoms such as physical weakness and fatigue, dry cough, soreness of the waist and knees, and premature graying of hair. After harvesting, Polygonatum needs to be screened to remove parts that are uneven in shape or of poor quality.

[0003] For example, Chinese document CN213792687U describes a multi-stage screening device for traditional Chinese medicine, comprising a collection hopper with movable pulleys at the four corners of its bottom surface. Symmetrical supports are positioned on both sides of the collection hopper, and multiple supports are linearly spaced at equal intervals above the supports. A screening hopper is located between the symmetrical supports on both sides. A synchronous motor is fixed to the outer wall of the middle section of the right support B via a motor frame, and a drive mechanism is located on the inner wall of the middle section of support B. The structure is compact and reasonable, providing good screening results and preventing medicinal materials from failing to fall into the next stage screening hopper due to insufficient power during the screening process.

[0004] However, during the use of the above-mentioned screening device, the material on the screen will remain on the screening hopper, which will affect the screening effect of Chinese medicine. Secondly, the staff need to hold the Chinese medicine high in order to put it into the screening device, which increases the labor intensity of the staff. Utility Model Content

Smaller polygonatum particles pass through the first filter screen 10 and fall onto the second filter screen 11, which then further filters the polygonatum. The second filtration is performed. Smaller pieces of Polygonatum will pass through the second filter screen 11 and fall onto the discharge plate. The sieved Polygonatum will fall into the receiving box 13 for storage through the first filter screen 10, the second filter screen 11, and the discharge plate 12. The second pulley 19 drives the first pulley 18, the drive shaft 16, and the second bevel gear 17 to rotate through the first filter screen 10.
