Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery and equipment, and in particular relates to a rhizome plant harvesting and conveying device. Background Art

[0002] In recent years, the state has vigorously supported the development of the Chinese herbal medicine industry and promoted fully mechanized production operations. The number of rhizome plant harvesting machines has increased year by year, and chain transmission is generally used in the harvesting process. Usually, chain transmission is divided into two forms, namely chain plate type and net chain type. Since the gap between the chain plate type and the net chain type is too small, the soil landing effect is not good, which affects its operation efficiency and harvesting effect. In addition, the debris is not easy to be discharged during the transmission process, causing blockage at the end. When there is too much accumulation, the sprocket teeth will be entangled by the debris, resulting in tooth skipping, affecting the chain transmission effect. At the same time, the cleaning process is inconvenient, which seriously affects the operation efficiency.

[0003] Therefore, a new solution is urgently needed in the prior art to solve the above problems. Summary of the invention
