Description

Technical Field

[0001] The utility model relates to the technical field of Chinese medicinal material seed collection, in particular to a light seed collection device. Background Art

[0002] Dandelion, also known as dandelion, dandelion, and dandelion, is a perennial herb in the Asteraceae family. It has the properties of clearing heat and detoxifying, promoting diuresis and relieving stranguria, and reducing swelling and dispersing lumps. It can be used in a variety of ways, including oral decoction, topical application, or combined with other medicinal herbs. Stevia, a subtropical perennial herb, extracts stevioside from its leaves, which is 200-350 times sweeter than sucrose and has only 1 / 300 of its caloric value. It is a pure white, pleasant-tasting, and odorless natural sweetener used in food, beverages, pharmaceuticals, daily chemicals, brewing, and cosmetics. Regular consumption can prevent conditions such as hypertension, diabetes, obesity, heart disease, and dental caries. Currently, the cultivation of Chinese medicinal herbs is rapidly developing. However, due to the small size, light weight, and high density of transplanted seeds of Chinese medicinal herbs such as dandelion and stevia, harvesting seeds from field cultivation is difficult. The seeds of dandelion and stevia are small and slender. The weight of dandelion seeds is 0.8 to 1.2 grams per thousand, and the weight of stevia seeds is 0.3 to 0.4 grams per thousand. The seeds are light and have pappus attached to them. When the flowering seeds mature, these light seeds are easy to scatter, usually drifting away with the wind, making them inconvenient to collect. If the seeds are picked manually, many seeds are likely to be shaken off, so the loss of manual collection is relatively large. If a machine is used to collect these light seeds, the collection range of the equipment is limited and it is easy to bring about large airflow. The light seeds around the machine will be affected, which will also cause the seeds to fall and cause losses.

[0003] The unique characteristics of the mild seeds of this type of traditional Chinese medicine necessitate the use of specialized seed collection devices to collect mature seeds. For example, while there are numerous types and specifications of stevia seed collection devices currently available, Chinese patent publication CN108112351A discloses a stevia seed harvesting device and method. The harvesting device comprises a handpiece, a collection box, and a harvester. The handpiece is snap-fitted to the collection box, and the harvester is connected to the collection box. The handpiece comprises a housing, a motor, a centrifugal fan, and an air filter. The motor, centrifugal fan, and air filter are all located within the housing. The centrifugal fan rotates at high speed to create a vacuum within the collection box. The harvester, holding a handle, directs the suction nozzle toward the mature stevia seeds to collect the seeds. This maximizes the recovery of mature seeds while minimizing the collection of immature seeds, thereby improving seed yield and quality without damaging the stevia plants or affecting the subsequent growth and development of the immature seeds. However, the existing stevia seed collection device has the disadvantages of high labor intensity due to handheld operation, small size, low harvesting efficiency, time-consuming and labor-intensive seed harvesting, and is not suitable for harvesting seeds of Chinese medicinal materials for field-scale planting. It is also unable to simultaneously sort seeds from impurities such as discs and pappus, and cannot meet actual needs. Summary of the Invention
