Description

A grain impurity sorting device

technical field

The utility model relates to the technical field of sorting devices, in particular to a grain impurity sorting device.

Background technique

After corn is threshed, impurities such as husks and skins will be produced in addition to corn granules. In order to ensure the quality of the finished corn granules in the later stage, impurities such as husks and skins need to be separated from the corn granules. The existing method of removing impurities from corn granules is to operate by using a screw conveyor.

During the impurity removal process, the screw conveyor will first move the corn grains and impurities to a high place, and then remove the corn grains and impurities from the connecting pipe at one end of the screw conveyor. However, during this process, light impurities such as shells and skins are scattered everywhere in the workplace, polluting the surrounding environment, and it is inconvenient to collect and process impurities.

The main reason for the above problems is that when light impurities such as hulls and skins are removed from the connecting pipe provided at one end of the screw conveyor, under the action of buoyancy in the air, the light impurities such as hulls and skins will fall slower than solid corn grains, so that the light impurities such as hulls and skins will scatter and move in the working environment with the flow of air, causing the working environment to be polluted. Centralized recovery increases the difficulty of later cleaning. In view of the above situation, we propose a grain impurity sorting device.
