PNEUMATIC LOADING DEVICE OF HARVESTER-THRESHER Russian patent published in 2013 - IPC A01D41/12 A01F12/60 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry and can be used for transportation of grain into the harvester hopper. The pneumatic loading device comprises a grain auger which feeds the grain into the transport pipe. The air flow is discharged with the fan to the transport pipe end to provide the grain movement through the pipe into the depression chamber. In the lower part of the depression chamber the output window is located which is directed to the bottom of the hopper. The depression chamber is connected to the diffuser of the hydrostatic transmission through the air duct and elbows. The transport pipe with the depression chamber is mounted horizontally in the upper part of the hopper. In the depression chamber the grain mass with the air discharged from the fan is facing the oncoming airflow from the cooling system of the hydrostatic transmission. At the flows meeting in the depression chamber the grain falls by gravity through the outlet window to the hopper bottom.

EFFECT: when moving the grain to the hopper with the air flow is not subject to crushing and damage.
