Description

Cereal impurity sorting unit

Technical Field

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

Background

After threshing, corn can produce impurities such as husks except corn particles, so that the impurities such as husks are required to be separated from the corn particles in order to ensure the quality of finished products of the corn particles in the later period, and the conventional corn particle impurity removal mode is operated by using a screw conveyor.

The screw conveyer moves corn particles and impurities to a high position together in the impurity removal process, then the corn particles and the impurities are moved out of a connecting pipe positioned at the high position of one end of the screw conveyer, but the impurities such as light shells and the like fly around in a working site in the process, so that the surrounding environment is polluted, and the impurities are inconvenient to collect and treat in a concentrated mode.

The main reason that above-mentioned problem appears is that when impurity such as light shell and skin shifts out in the connecting pipe that screw conveyer one end set up, impurity such as light shell and skin can be slower than solid maize granule's decline speed under the effect of buoyancy in the air for impurity such as light shell and skin can scatter in operational environment along with the flow of air and remove, cause operational environment to be polluted, and impurity such as light shell and skin of scattering everywhere can drop everywhere in the place of working, make can not concentrate the recovery to impurity wherein mixing in the separation maize, increased the degree of difficulty of later stage clearance, to above-mentioned circumstances, we propose a cereal impurity sorting unit.
