[0021] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0022] like Figures 1-5 As shown, a chain-screen type root and rhizome medicinal herb digging and harvesting machine includes a frame, a shovel 1, a conveying assembly 2, and a soil-removing wheel assembly 7. The shovel 1 is located at the front end of the frame, the conveying assembly 2 is located in the frame for conveying the medicinal herbs shoveled out by the shovel 1, and the soil-removing wheel assembly 7 is located at the rear end of the frame. The soil-removing wheel assembly 7 includes a rotating frame, which is rotatably mounted on the frame. The rotating frame includes several ring-arranged dispersing rods 71 ​​and a connecting plate, and the multiple dispersing rods 71 ​​are all connected to the outer periphery of the connecting plate.

[0023] The frame moves forward under traction, and the blade 1 digs out the medicinal herbs from the soil in sequence. The dug-out herbs will reach the conveying component 2, which can transport the herbs to the rear end. During the transport process, the soil attached to the herbs will gradually fall off the conveying component 2. When the herbs are at the rear end of the conveying component 2, as the conveying component 2 continues to move, the herbs reach the soil removal wheel group 7. As the herbs move on the soil removal wheel group 7, the dispersing rod 71 in the soil removal wheel group 7 continuously contacts and collides with the herbs, and the soil on the herbs is continuously broken up and continued to be transported to the tail end of the entire harvester, completing the entire harvesting process.

[0024] Under the action of the soil removal wheel group 7, the medicinal materials continuously come into contact with and collide with the dispersing rod 71, further dispersing and removing the soil from the medicinal materials. Furthermore, since the soil removal wheel group 7 also has a certain transportation function, the medicinal materials will continue to be transported backward and will eventually be located at the rear of the entire harvester, thus avoiding the risk of the medicinal materials being crushed by the rear wheels set on the frame.
