Efficient discharging mechanism and screening equipment for pinellia ternate processing

Abstract

The invention relates to the technical field of screening equipment, and discloses an efficient discharging mechanism and screening equipment for processing pinellia ternata, the efficient discharging mechanism comprises a discharging barrel with a rectangular longitudinal section, a discharging door capable of being opened and closed, a fixing frame and two clamping frames, the fixing frame is used for fixing a material containing bag, and the cross section of the fixing frame is round or oval; a limiting ring is arranged in the middle of the outer side of the fixing frame, a limiting groove is formed in the middle of the inner side of each clamping frame, and the driving assembly simultaneously drives the two clamping frames to be pressed on the outer side of the fixing frame and drives the discharging door to be opened or closed. The driving assembly is arranged, the clamping frame can be driven to be pressed on the outer side of the fixing frame and the discharging door can be driven to be opened or closed at the same time, discharging can be achieved only by correspondingly operating the driving assembly, the bag opening of the flexible bag does not need to be continuously held by hands, and operation is rapid, easy and convenient; and when a new flexible bag needs to be replaced, the machine does not need to be stopped, continuous discharging is achieved, and the discharging efficiency is high.

Description

technical field [0001] The invention relates to the technical field of screening equipment, in particular to an efficient discharging mechanism and screening equipment for pinellia processing. Background technique [0002] Pinellia is a traditional Chinese medicine, which is the dried tuber of Pinellia ternata (Thunb.) Breit. Excavated in summer and autumn, washed, removed the skin and fibrous roots, and dried in the sun. It is distributed in Northeast China, North China and the Yangtze River Basin. It has the effects of drying dampness and resolving phlegm, lowering adverse flow and relieving vomiting, eliminating mass and resolving mass. Pinellia collected from Yaonong is usually mixed with stones or other impurities, and the size is different, so it needs to be cleaned to remove stones or other impurities mixed inside, and then sieved to classify Pinellia according to its size. The processing of pinellia can be carried out in subsequent steps after the above treatment....

AI Technical Summary

Problems solved by technology

[0003] Among them, screening equipment needs to be used in the screening step, and pinellia is entered from the feeding port of the screening equipment, and then into the screening box, the core component of the screening equipment, in which several layers of different apertures are obliquely arranged. The screen, the screen divides the screening box into different screening chambers, and the side of the screening box is generally equipped with a power mechanism, which drives the vibration of the screen, Pinellia shakes with the vibrating screen, and the aperture of the upper screen is larger than that of the lower layer The aperture of the sieve, the pinellia whose size is smaller than the aperture of the sieve falls to the next layer of sieve, and the side of the screening box is also provided with several outlets connected with each screening chamber, and then the pinellia on each layer of sieve The material is discharged from the discharge port. Usually, a flexible bag is placed under the discharge port. The pinellia that falls from the discharge port falls into the flexible bag and is collected. In the above process, it is always necessary to hold the mouth of the flexible bag to The flexible bag is dumped, and after the flexible bag is full, it is necessary to close the screening equipment to stop the discharge, replace the empty flexible bag, and then restart the screening equipment to discharge, so continuous discharge cannot be achieved, and the discharge efficiency is low
