[0002] The harvesting of Chinese medicinal materials has always been mainly done manually, which is labor-intensive, inefficient, poor quality and high cost, and is a bottleneck restricting the development of the Chinese medicinal materials industry. In recent years, with the rapid development of agricultural machinery, the research and development of Chinese medicinal materials harvesting machinery has also received widespread attention from the society. From the initial single mechanical loosening of the soil, combined with manual soil cleaning and picking operations to complete the harvesting work, it has developed into a mechanical complex operation that completes the harvesting in one go.

[0003] However, judging from the current situation of mechanical complex operations, there are still many problems and shortcomings. It is far from achieving the state of complete removal of soil from the roots of medicinal materials. A considerable amount of manual work is still needed to assist, and there is a great waste and loss in manpower, material resources, and quality.

[0004] The invention patent with application number 2013107294849 disclosed a rhizome medicinal material harvesting machine. After several years of use, its desoiling effect can no longer meet the requirements of modern agricultural production and needs to be further improved. Summary of the invention

[0007] As a preferred solution of the present invention, a lifting buffer device is provided on the loosening mechanism.

[0008] As another preferred solution of the present invention, a shaft curtain is arranged at the rear of the frame corresponding to the stripping mechanism.

[0009] Beneficial effects of the present invention.

[0010] The present invention uses a soil-lifting shovel to lift the branches and leaves of crops together with the rhizomes from the ground, and moves them upward under the drive of the transmission screen chain, and cooperates with the floating mechanism to cut the root part of the crop; after the root part of the crop is cut, it is more conducive to improving the soil removal effect; the divided crops continue to rise under the action of the transmission screen chain to the removal mechanism, and the removal work is completed under the vibration of the removal mechanism. The whole process is completed at one time without human participation, with a high degree of automation, high production efficiency and easy use.

[0011] The soil loosening mechanism of the present invention is provided with a buffer device, so that the soil loosening mechanism can float up and down, thereby avoiding damage when encountering hard stones or the like.

The upper end of the rocker rod 9 is connected to one end of a transverse rod 10; the other end of the transverse rod 10 is connected to the eccentric wheel assembly 12 on the output shaft 17.

[0026] The eccentric wheel assembly 12 connected to the transverse rod 10 and the eccentric wheel assembly 12 connected to the lifting rod can be the same eccentric wheel assembly 12 or two different eccentric wheel assemblies 12 .

[0027] The floating mechanism 3 includes a fixed horizontal axis 23 fixedly connected to the frame 14, and floating arms 24 are provided at both ends of the fixed horizontal axis 23. A floating rotating shaft 26 is provided between the ends of the two floating arms 24, and a rotating tooth 25 is provided on the floating rotating shaft 26; the output shaft 17 is connected to the floating rotating shaft 26 through a floating chain sprocket assembly 4.
