Multistage and multistep screening machine used for short-pedicel aconite root seeds

Abstract

The invention discloses a multistage and multistep screening machine used for short-pedicel aconite root seeds. The multistage and multistep screening machine comprises a winnowing box, a screening box and a damping base plate. The winnowing box and the screening box are arranged at the top end of the damping base plate. Multiple supporting legs are evenly arranged at the bottom end of the dampingbase plate. A feeding hole is formed in the top end of the winnowing box. A first slag discharging pipe is connected to the top of the left side end of the winnowing box in a communication manner. The right side wall of an inner cavity of the winnowing box is fixedly connected with a gas spraying device. A first screening net is arranged at the middle portion of the inner cavity of the winnowingbox. Supporting plates are arranged on the left side wall and the right side wall of an inner cavity of the screening box. A second screening net is arranged at the top ends of the two supporting plates. The bottom end of the screening box communicates with a discharging hole in a communication manner. By means of the multistage and multistep screening machine used for short-pedicel aconite root seeds, the gas spraying device is used for winnowing the seeds, and stem leaves and shriveled seed impurities in the seeds are removed; and the first screening net is arranged for screening fine solidparticle impurities, the second screening net is arranged for conducting large particle impurity screening, rounds of screening are conducted step by step and are matched, and it is ensured that the impurities of the seeds are completely removed.

Description

technical field [0001] The invention relates to the technical field of planting and processing of Chinese herbal medicines, in particular to a multi-stage and step-by-step screening machine for the seeds of Artemisia indica. Background technique [0002] Artemisia spp., also known as Aconitum short handle, belongs to the genus Aconitum of Ranunculaceae, and is mainly distributed in Yunnan, Sichuan, Tibet and other provinces. Because the rhizome of Artemisia spp. contains a variety of alkaloids such as artemisinin, it is used in the folk to treat rheumatic pain, bruises, analgesia, etc., and is an important medical raw material in my country. However, with the development of Artemisia spp. Utilization, the wild survival of Artemisia spp. has decreased rapidly, and it has become an endangered species. Artificial cultivation is an effective way to protect resources and ensure utilization. [0003] Artemisia A, B, C, and D all have analgesic effects, and the total alkaloids of F...

AI Technical Summary

Problems solved by technology

At present, the sieve holes of the vibrating sieve are mainly used to separate the impurity seeds of Artemisia spp. The structure of the vibrating sieve is simple, and it can only screen some small stones, clods and silt, but it cannot screen out the impurities and quality that are larger than the seeds. Light inferior seeds, etc., and the stems and leaves mixed in the seeds cannot be screened out in time, which will affect the quality of subsequent Chinese medicine seedlings
