SELF-PROPELLED GRAIN HARVESTER Russian patent published in 1997 - IPC

FIELD: agricultural engineering. SUBSTANCE: combine harvester has header and elevator for delivery of cut plants to threshing mechanism arranged behind the header. Threshing mechanism has concave and threshing drum with threshing segment spaced over its perimeter. Segments are made in length of drum is form of row of separate members displaced in each row relative to each other. Transmitting drum with working members spaced over its perimeter is arranged behind threshing mechanism. Working members of this drum located in front of inlet hole of divider housing or in holes of divider housings are made in form of row of carriers displaced in each row relative to each other. Transmitting drum is partially enclosed by inlet sheet guides made to suit its outer diameter to which sheet guides overlapping the space between inlet sheet guides and divider housing are connected. Threshing segments shift plant mass in radial flow and working members of divider rotor of separator shift mass in axial flow opposite to direction of movement of combine harvester. Cut plant mass passes in uniform and loose flow throughout the machine, and delivery of mass to working positions is carried out in spared manner thanks to which head can be excluded, common drive can be protected from torque peak values and optimum separation of grain can be provided. EFFECT: improved operation. 11 cl, 11 dwg
