Conventionally, in this type of combine harvester, a radiator is placed behind the engine in the longitudinal direction of the machine.
The structure is such that exhaust air from the radiator is discharged through an exhaust outlet provided on the rear end surface of the engine bonnet, and the dust discharged from the threshing section dust outlet is There was a device that exerted an air curtain effect with the exhaust air from the radiator to prevent early clogging of the radiator inlet (Utility Model Opened in 1988).
Publication No. 77347).

Although it is certainly possible to obtain an air curtain effect with the conventional configuration, the direction of exhaust air from the radiator is horizontal at a height approximately equal to the installation height of the radiator. Until the phenomenon in which the dust discharged from the dust exhaust port once falls to the ground, resurfaces, and attaches to the air intake port provided on the side of the engine bonnet, the dust wraps around. I couldn't stop it.

As a result, by simply modifying the settings of the exhaust outlet of the muffler, which is normally installed under the hood, an air curtain effect can be created that organically links the exhaust air from the radiator and the exhaust from the muffler. This makes it possible to prevent early clogging of the suction port without providing a shielding plate.
