[0001] The utility model belongs to the field of mechanical design, and relates to a harvesting device for medicinal material seeds, in particular to a harvesting device for Chinese medicinal material Polygonum capitatum seeds, and more particularly to a device for efficiently collecting Polygonum capitatum seeds. Background Art

[0002] The original plant of Polygonum capitatum Buch.-Ham. ex D.Don belongs to the Polygonum genus of the Polygonaceae family. Its medicinal parts are the above-ground parts or the whole plant, which can be used fresh or dried; it has been included in the "Quality Standards for Traditional Chinese and Ethnic Medicinal Materials in Guizhou Province" (2003 edition).

[0003] Polygonum capitatum tastes bitter and pungent, and is cool in nature. It enters the kidney and bladder meridians. It has the functions of clearing away heat and dampness, promoting blood circulation and dispersing blood stasis, and promoting diuresis and relieving stranguria. It is mainly used to treat dysentery, pyelonephritis, cystitis, urinary tract stones, pelvic inflammatory disease, prostatitis, rheumatism, injuries from falls, sores, eczema and other diseases.

[0004] Polygonum capitatum has a long history of medicinal use. It was first recorded in the "Guangxi Chinese Materia Medica" (1963, Volume 2), mainly used to treat rheumatic pain; it was included in the "Dictionary of Chinese Medicine" (1977, Volume 1) in 1977, mainly used to treat dysentery, nephritis, cystitis, urinary stones, etc.; it was also included in the "Guizhou Miao Medicine Research and Development" (1999), "Guizhou Province Chinese Medicinal Materials Quality Standards" (1988 edition) and "Guizhou Province Chinese Medicinal Materials and Ethnic Medicinal Materials Quality Standards" (2003 edition).

[0005] Polygonum capitatum is a commonly used medicinal material for ethnic groups and is widely used. It has different names in different regions and ethnic groups. According to field and literature surveys, Polygonum capitatum has more than 20 aliases. For example: Four Seasons Red (Guizhou Chinese Medicinal Materials Quality Standards 1988 Edition), Small Red Vine (Guangxi Plant List), Water Hydrangea, Provincial Ding Grass (Guizhou Chinese Herbal Medicine List), Red Sour Rod, Stone Flower, Stone Vegetable (National Chinese Herbal Medicine Compilation), Stone Mang Grass, Stone Polygonum (Guangxi Chinese Herbal Medicine Records), Sun Grass (Yunnan Chinese Herbal Medicine), Red Ground Red, Fire Pomegranate Grass (Wenshan Chinese Herbal Medicine), Red Flowered Ground Ding, Jingfeng Grass, Small Copper Grass, Small Red Grass (Yunnan Chinese Herbal Medicine Selection), Physalis, Grass Stone Pepper, Sun Flower (Yunnan Seed Plant List), Copper Mine Grass (Sichuan Chinese Herbal Medicine Records), Rock Buckwheat, Green Shadow (Hubei Flora), etc.

[0006] Polygonum capitatum is also used as medicine by many ethnic minorities, especially the Miao medicine, which is the most commonly used by Miao doctors; its name is "Dlobdongd xok" (similar to the Chinese transliteration of "sou dang suo"). "Si Ji Hong" is the name of the most commonly used herbal medicine among ethnic minorities in Guizhou; ethnic minorities in some places in Guizhou also call it "Man Di Hong" and "Gu Ding Pao".

[0007] Guizhou has extremely rich wild Polygonum capitatum resources, which are distributed throughout the province and are widely used by Guizhou's ethnic groups (especially the Miao people). Since the 1980s, relevant scientific research institutes in Guizhou have conducted research on its resources, chemistry, efficacy and clinical application, and have developed a single-ingredient Polygonum capitatum medicine preparation, "Relinqing Granules".

[0008] Although wild Polygonum capitatum resources are extremely abundant, in the production process of Chinese medicinal materials required for the industrialization of Chinese medicine preparations, it is hoped that a good method can be found in the process of medicinal material planting, especially in the process of medicinal material planting, to ensure the high-quality and continuous supply of medicinal materials for preparation production, so as to ensure the source of medicinal materials and stabilize the quality of medicines.

[0009] The invention patent CN103460933A (201310407149.7) of the applicant involves a method for constructing a remote planting and preservation nursery for the germplasm resources of Polygonum capitatum, the original medicinal material of Relinqing Granules.

The good method of the invention can ensure the high-quality and continuous supply of medicinal materials for preparation production, so as to ensure the source of medicinal materials and stabilize the quality of medicines.

[0012] With the increasing market demand for Polygonum capitatum, its planting area has also increased year by year. Polygonum capitatum is one of Guizhou's authentic ethnic medicines, with large production and wide cultivation areas in Guizhou. At present, the harvesting of Polygonum capitatum seeds is mainly done by manual picking, which involves manually picking the fruit sequences, then drying them, and then manually rubbing, sorting, and collecting them. This method consumes a lot of manpower, has high work intensity, and is inefficient, making it difficult to meet the needs of large-scale harvesting.

[0013] Polygonum capitatum medicinal materials need to be sown every year, which requires a lot of seed collection work. The prior art discloses some devices or equipment for collecting plant seeds. For example, the seed collection device provided by CN218007097U (202221680084.4) includes a vertical pole; a drill bit, which is detachably connected to one end of the vertical pole; at least one collection tray, which is installed on the vertical pole, and the collection tray is used to collect plant seeds.

[0016] CN116210453A (202310149847.5) discloses an alfalfa seed collection device, which consists of a main body, a transmission, a collection and collection device. As a semi-feeding pre-cutting threshing and collection machine, it does not cut alfalfa plants, but only collects seeds. It is believed that when the application is working, as the device moves forward, the front ends of the left and right collection boxes gather the alfalfa plants, and the gathered plants are sent into the left and right collection boxes and contact the left and right threshing drums rotating in the left and right collection boxes. The gathered alfalfa plants are combed and brushed from top to bottom by the flexible comb teeth on the left and right threshing drums rotating in the opposite directions. The alfalfa seeds brushed out are sucked into the collection box under the combined action of the negative pressure generated by the left and right threshing drums rotating in the opposite directions and the negative pressure generated by the suction of the collection box, and then output by the bellows installed on the outside of the collection box, thereby achieving a high-efficiency alfalfa seed collection method combined with positive and negative pressure airflow and mechanical combing.
