Description

Technical Field

[0001] The utility model relates to the technical field of a pinellia and fritillaria harvester, in particular to a traction-type pinellia and fritillaria harvester. Background Art

[0002] The traditional Pinellia and Fritillaria harvester has an L-shaped drug chain plate with low strength. In order to improve the separation rate of drug soil, holes are opened on the chain plate, which further reduces the strength. At the same time, the gap between the traditional L-shaped chain plate and the sprocket wheel is increased, which is easy to leak and damage the drug. At the same time, the large particles of the excavated drug soil are not crushed, so these lumps are mixed in, which brings trouble to the subsequent screening work. Secondly, the screening device on the machine has poor screening effect and does not meet the requirements of the back-end process. Utility Model Content
