SELF-PROPELLED COMBINE HARVESTER WITH FEED DRUM Russian patent published in 2024 - IPC A01D41/12 A01F12/10 A01F7/06 

FIELD: agriculture.

SUBSTANCE: self-propelled combine harvester comprises a separating device, which contains two axial rotors with an inlet part located in front of them and with an inlet segment located in front of the inlet part, as well as a supply drum with a side surface, which is located in front of the separating device and is provided for supplying a flow of the harvested crop into the separating device. Feeding drum is made in the form of a separating drum which divides the flow of the harvested crop into two partial flows. Feeding drum in the middle part of the side surface contains V-shaped guide elements arranged in the circumferential direction. Feeding drum in the outer part of the side surface contains other side guide elements, which are located, in fact, inclined to the flow of the harvested crop. Feed drum on the side surface also has another guide elements which essentially pass along the side surface, and which are located, in fact, between the V-shaped guide elements and the side guide elements. At least V-shaped guide elements and/or side guide elements are located at a distance from substantially longitudinal guide elements. Each of the guide elements comprises a holder rigidly connected to the side surface of the supply drum, as well as a removable wearing element located in the direction of rotation. Wear element covers, in fact, the surface of holders in direction (19) of rotation.

EFFECT: improved distribution of the harvested crop between axial rotors.
