Screening device for Dendrobium officinale production

Abstract

The invention discloses a screening device for Dendrobium officinale production. The screening device comprises a support, an angle adjusting mechanism, a screening frame, a screen limiting and replacing structure and a screen amplitude control mechanism; clamping grooves are formed in the two sides of the support in a penetrating mode; the angle adjusting mechanism is arranged below the support; the screening frame is movably installed in the support; the two ends of the screening frame are each provided with two limiting bolts; one end of each limiting bolt penetrates through the support to be fixedly connected with a limiting ring; springs are arranged on the outer sides of the limiting bolts in a surrounding mode; and the screen amplitude control mechanism is arranged at one end of the outer side of the screening frame. A servo motor is controlled to rotate, then a supporting frame is controlled to move on the base, a convex block arranged on the supporting frame is matched with the grooves to move in the horizontal direction, and then the position of a motor installed on the supporting frame is changed, so that the distance between a polarization block and the screening frame is changed, the amplitude of the screening frame caused by the polarization block is changed, and the vibration amplitude of the screening frame is adjusted.

Description

technical field [0001] The invention belongs to the field of production of dendrobium candidum, in particular to a screening device for production of dendrobium candidum. Background technique [0002] Dendrobium candidum, also known as Tiepilan, Iron Chlorophytum, Lishucao, commonly known as Black Festival Grass in Yunnan. It is distributed in the mountainous areas of Anhui, Zhejiang, Yunnan, Guizhou, Sichuan and other places south of Qinling and Huainan in my country. Its unique medicinal function, make it widely exploited. [0003] In the production process of Dendrobium officinale, it needs to go through many processes such as picking, screening, frying, peeling, wrapping, and baking. In the screening process, it is necessary to further screen the picked Dendrobium officinale, and shake It filters. [0004] There are following deficiencies in existing dendrobium candidum screening device: [0005] 1. The screen cannot be replaced according to the screening requirements;...
