[0002] At the present stage, with the diversified development of agriculture, field crops in many areas are gradually transformed into cash crops. The planting area of deep-rooted cash crops (such as burdock, astragalus membranaceus, liquorice, etc.) is getting larger and larger, but the subsequent harvesting problems are becoming more and more prominent. Relying solely on manual harvesting not only has a high labor intensity, but also has a high cost, delays agricultural seasons, and reduces the income of farmers. The mechanized operation of medicinal material harvesting has developed rapidly due to the urgent demand to solve problems such as low production efficiency and high labor intensity in manual excavation of medicinal materials. While saving the cost of medicinal material excavation, it liberates farmers from heavy physical labor.

[0003] The Chinese authorized patent document with the publication number of CN219644566U discloses a new type of traditional Chinese medicine harvester, including a frame, a driving member is arranged on the upper part of the frame; a front shovel is arranged at the front end of the frame for excavating medicinal materials; a first sieve part is arranged behind the front shovel; a second sieve part is arranged behind the first sieve part, and the lower end of the second sieve part is located below the upper end of the first sieve part; a wheel frame is arranged in the middle of the frame, and a pair of traveling wheels are rotatably arranged at the bottom; a tail sieve is connected to the rear end of the frame through a swinging mechanism. When the utility model works, the harvested medicinal materials pass through the first sieve part and the second sieve part in sequence to complete preliminary soil screening and enter the swinging tail sieve, so that the medicinal materials and miscellaneous soil in the tail sieve are further screened and separated, thereby effectively reducing the soil content of the medicinal materials during the final collection.

[0004] In the above-mentioned prior art, the traditional Chinese medicine cannot be accurately positioned and picked from multiple angles, and at the same time, the picking and cutting efficiency is low, which easily leads to the phenomenon that the picked medicinal materials fall to the ground and are damaged.
