GRAIN HEADER FOR GRAIN HARVESTING MACHINE Russian patent published in 2021 - IPC A01D41/14 A01D57/20 

FIELD: agricultural engineering.

SUBSTANCE: grain header (11) for a combine harvester (100) includes a central section (13) and two side sections (15, 17), pivotally connected to the central section (13) and made with the possibility of rotation relative to the central section (13) for assuming the working configuration, in which the three sections (13, 15, 17) of the header are aligned with each other in the horizontal plane, and the original configuration or transport configuration in which the side sections (15, 17) of the header overlap the central section (13), while the sections ( 13, 15, 17), the headers are equipped with a support frame (19, 21, 23); a cutting device (29, 31, 33) coupled to the support frame (19, 21, 23) by means of a hydraulic suspension, while the cutting device (29, 31, 33) includes a blade having several substantially trapezoidal knives and capable of performing a pendulum motion using a mechanically driven control element, an eccentric reel supported on a support frame (19, 21, 23) by means of pivot arms, the transport belt conveyor (37, 39, 41), located behind along the cutter bar (29, 31, 33) and configured to feed the material cut by the cutter bar (29, 31, 33) back along the grain header ( 11) towards the rear of the header (11).

EFFECT: this design provides simplicity, reliability, operational flexibility and design versatility, low power consumption and requires less maintenance.
