A grain combined harvester comprises a chassis, a motor, a fuel tank, an operator’s cab, a tank with a downloading screw, a reaper part, a threshing-separating device including a cleaning fan with a drive, and a device for regulating air consumption which is delivered on cleaning sieves. In the wall of the fan spiral case near outlet thereof a window is made. The said window has a movable shutter with a drive and a collector with takeoff air-duct mains delivered into areas of the combined harvester which are fire hazardous by possible accumulation of highly inflammable plant residues and equipped with nozzles and stop valves made in such a manner as to allow smooth change of the passage area. |
