Buffering type dust removing and impurity removing device for grain

Abstract

The invention discloses a buffering type dust removing and impurity removing device for grain, and relates to the field of grain processing equipment. The device comprises a feeding mechanism, a housing, an air pump, a dust storing device and a spiral conveying device, wherein the spiral conveying device, the feeding mechanism and the housing are sequentially connected; the spiral conveying deviceis connected to the feeding mechanism through a connecting plate; a plurality of flow guide mechanisms are arranged in the feeding mechanism; a plurality of vibrating assemblies which are arranged ina mutual staggering manner are sequentially arranged on the inner wall of the housing from top to bottom; the air pump communicates with the inner part of the housing; and a feeding port of the duststoring device is connected to an air outlet of the air pump through a pipeline. With the adoption of the device, the grain feeding quantity can be controlled, and moreover, dust and impurity in the grain can be separated through the flow guide mechanisms and the vibrating assemblies, so that the environment is prevented from being polluted by dust. The device has the characteristics of being simple in structure, low in production cost, and convenient to operate.

Description

technical field [0001] The invention relates to the field of grain processing equipment, in particular to a buffer type grain dust and impurity removal device. Background technique [0002] my country's grain consumption is huge, so grain transportation is relatively frequent. Belt conveyors are usually used in the grain transportation process. When the belt conveyor is used, the grain is transported to the feeding end of the belt conveyor. The discharge end is located at the upper entrance of the granary. During the process of pouring the grain into the feeding end of the conveyor and lifting it, a large amount of light and fine impurities and dust in the grain will float into the air, causing the grain to fall into the air. There is a lot of dust in the warehouse, and a large amount of flying dust in the air will cause physical injury to the operators and pollute the environment; in addition, a part of the bran is mixed in the grain, which requires a series of cleaning to re...
