Description

Technical Field

[0001] The present application relates to the field of agricultural machinery, and more specifically, to a device for harvesting ophiopogon japonicus. Background Art

[0002] Ophiopogon japonicus, a Chinese medicinal material. This product is the dried root of Ophiopogon japonicus, a plant of the Liliaceae family. Functions and indications: nourishing yin and producing body fluid, moistening the lungs and relieving cough: used for lung and stomach yin deficiency, thirst, dry cough and hemoptysis; palpitations and fright due to insufficient heart yin, and heat damage to body fluid in the late stage of fever. It can be used with Adenophora scutellariae and Fritillaria cirrhosa to treat lung yin deficiency and dry cough. As a Chinese medicinal material, Ophiopogon japonicus is mainly taken from the root of Ophiopogon japonicus, so the stem and root of Ophiopogon japonicus need to be separated during processing. The patent document with the prior art publication number CN220972521U provides an Ophiopogon japonicus harvesting device, which can cut off the stem wrapped around the cutting strip by setting a baffle, so as to facilitate cleaning; at the same time, the baffle is set on both sides of the harvesting roller, so as to be away from the falling area of ​​the root block, so that the wrapped stem will not be cut off in the falling area, and the stem is cut off at a position close to the side wall of the harvesting box, so that the fallen root block and the smaller stem are separated and fall in different areas.

[0003] With respect to the above-mentioned related technologies, the inventor believes that the device relies on the opposite rotation of two harvesting rollers to cut off the roots during use, but at the same time, the stems and leaves of Ophiopogon japonicus will be cut off and mixed in, which will increase the subsequent screening process. Therefore, we propose an Ophiopogon japonicus harvesting device. Utility Model Content
