FIELD: agriculture.
SUBSTANCE: device comprises an aspiration chamber connected to the loading device of supplying the initial material. This device is a loading hopper comprising at least two bent sheet segments arranged in pairs at a distance from each other in the upper part of the air channel. The said sheet segments form in the upper part of the air channel the confuser section for the air flow distribution. These sheet segments also form the barriers which are arranged in the lower part of the loading hopper. And in the air channel a valve is mounted, made from a sheet material of bent configuration. The lower part of this valve provides the ability of covering the window of the air channel. The middle part of the valve in the bent zone provides the ability of dosed pouring of the grain mass into the window of the air channel.
EFFECT: improvement of quality of separation of light fractions of bulk materials.
