Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a novel rehmannia glutinosa harvesting device. Background Technique

[0002] Rehmannia glutinosa is a perennial herb of the genus Rehmannia in the family Scrophulariaceae. Its rhizome is fleshy, yellow when fresh, the stem is purplish red, the leaves are ovate to oblong-elliptic, green on the upper side, slightly purple or purplish red on the lower side. Rehmannia glutinosa has an important position in traditional Chinese medicine and is used as the raw material for a variety of medicinal materials. Fresh rehmannia glutinosa and dried rehmannia glutinosa have different effects. According to the "Compendium of Materia Medica", fresh rehmannia glutinosa has the effects of clearing heat and promoting fluid production, cooling blood, and stopping bleeding, while dried rehmannia glutinosa has the effects of clearing heat and cooling blood, nourishing yin and promoting fluid production;

[0003] When harvesting rehmannia glutinosa, tools such as shovels or sickles should be used to cut off the stems and leaves above the ground. Pay attention not to cut too deep to avoid damaging the roots. Then, dig along one side of the ridge. The depth should be appropriate so as not to damage the rhizome. Because rehmannia glutinosa is easy to break, special care is needed during excavation. At the same time, the harvested rehmannia glutinosa should be promptly subjected to preliminary processing to remove soil, grass roots and impurities;

[0004] At present, during the process of harvesting rehmannia glutinosa, although the rehmannia glutinosa can be harvested manually, the workload on personnel is relatively large and it consumes a lot of manpower. Some novel rehmannia glutinosa harvesting devices use a semi-mechanized form to dig the rehmannia glutinosa underground. Although this method does not require manual digging, subsequent manual picking and collection of the turned-out rehmannia glutinosa are still needed. At the same time, during the collection process, the operator also needs to clean the soil adhered to the outer surface of the rehmannia glutinosa to prevent the soil from affecting the purity and quality of the rehmannia glutinosa. The operation is troublesome and the harvesting efficiency is relatively low. Therefore, we propose a novel rehmannia glutinosa harvesting device. Content of the Utility Model
