VENTILATED HOPPER Russian patent published in 2020 - IPC A01F25/14 A01F25/22 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, namely to devices for temporary preservation and drying of seeds during post-harvest processing of grain crops. Ventilated hopper contains a perforated body enveloping it with a gap tight housing, an air distribution pipe installed in the body with a valve installed in it with the possibility of movement, a system connected to an air distributing pipe with a delivery fan, a gate valve. Sealed housing is made in the form of a series of tight shaped cases, rigidly fixed to the outer surface of the perforated housing. Air distribution pipe with pressure fan via shutter is connected through pipe to header, which through pipes is rigidly connected with sleeves on one side, which on the other side are rigidly connected to branch pipes of figured casing bottom, at that their holes are covered with valves. Outer surface of perforated housing and inner surface of shaped casings form additional air-distributing pipes, total volume of which is more than volume of main air-distributing tube. Side outer surfaces of valves are mating lateral inner surfaces of additional air distribution pipes.

EFFECT: technical result is simple design and high efficiency of granulating grain in hopper.
