An automatic soil notoginseng harvester

Abstract

The invention relates to the field of sedum aizoon picking machines, in particular to an automatic sedum aizoon harvester. The automatic sedum aizoon harvester comprises a harvester body, a shoveling device, a primary soil screening device, a screw conveying device, a conveying device, a secondary soil screening device and a shell. The shoveling device is located in front of the harvester body, the primary soil screening device is located at the rear end of the shoveling device, the screw conveying device is located at the rear end of the primary soil screening device, the conveying device is located at the right end of the harvester body, and the secondary soil screening device is located behind the harvester body. Sedum aizoon can be dug out automatically on a large scale, two times of soil screening are carried out, the automation degree is high, and a large quantity of manpower and material resources is saved.

Description

technical field [0001] The invention relates to the field of soil notoginseng harvesting machinery, in particular to an automatic soil notoginseng harvester. Background technique [0002] Soil notoginseng: also known as water notoginseng, water field seven, etc., soil notoginseng is a perennial herb with a height of about 25 cm. There are hypertrophic tubers underground, oblong, 2-4 cm long, about 1.5 cm in diameter, white, often curved and horizontal in the soil, with many fibrous roots. Leaves basal, leaves elliptic-lanceolate, 10-20 cm long, 3-5 cm wide, apex acuminate, base decelerating slightly clasping, margin entire, upper veins concave, convex on back, both sides glabrous. In late summer and early autumn, the scapes are pulled out from the leaves, and more than 10 flowers grow at the top, forming an umbel, with 4 involucral bracts, and the outer 2 are larger. The flowers are bisexual and neat. The pedicel is 1-1.5 cm long and the bracts are linear. , perianth bell-...

AI Technical Summary

Problems solved by technology

[0005] However, in the prior art, there is no special equipment for excavating notoginseng. At present, excavating soil notoginseng is mainly performed manually, and then dried for use. This is time-consuming and laborious, greatly reducing work efficiency, and the soil Panax notoginseng tuber itself is toxic. Symptoms of poisoning will appear 30-60 minutes after taking 15-30 grams, manifested as nausea, vomiting, abdominal pain, diarrhea, etc., and some people's alanine aminotransferase will increase significantly after taking it for 3 days; Excavating the soil of notoginseng may also have adverse effects on the human body
