TRANSPORT CHANNEL OF FORAGE HARVESTER PROCESS MASS MOVEMENT WITH AIR ACCELERATING DEVICE Russian patent published in 2020 - IPC A01D43/77 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, namely to self-propelled harvesters equipped with transport channel intended for direction of process mass from one working element to another and its unloading into vehicle body. Transport channel of process mass movement includes diffuser, confusor and silage duct, also pneumatic accelerator and pneumatic nozzles are introduced. Pneumatic accelerator is installed between confusor and diffuser, and nozzles are installed in places of bends and in points of change of cross-section of transport channel and silage duct, along perimeter of transport channel, as well as in pneumatic accelerator. Pneumatic injectors are installed so that accelerating air flow is created in direction of process mass movement.

EFFECT: reduced wear of the walls of the transport channel, increased carrying capacity, elimination of clogging of working elements by process mass and increased efficiency of self-propelled combine harvester in general.
