2. Description of the Related Art In a combine harvesting operation, a worker operating a driver's seat provided on the upper side of a traveling platform is used to start an engine provided below the cockpit.
By operating the combine, the reaping culm is cut by the front mowing machine, and the mowing culm is transferred to the upper rear by the mowing machine, supplied to the threshing machine, and threshed while being pinched and transported in the threshing machine. The threshed and sorted kernels are temporarily stored in the combine.

[0003] During the harvesting operation, the hot air generated from the engine is exhausted from an air outlet provided at a lower portion of a horizontal partition plate provided on one side of the engine to exhaust the hot air. . The discharged hot air rises, passes through the side of the cockpit and is discharged, or is directly discharged to a cutting input pulley that drives a reaper provided on the side of the horizontal partition plate. Be winded.

[0004]

The hot wind generated from the engine passes through the side of the operator who operates the vehicle while riding in the cockpit, so that a hot and comfortable harvesting operation may be performed depending on the timing of the operation. Or the hot air is directly exhausted to the reaping input pulley that drives the reaper, so that the reaping belt stretched over the reaping input pulley is stretched and reliable transmission is not possible, or Although the life of the reaping belt has been shortened, the present invention is intended to solve these problems.

[0008]

In the combine harvesting operation, the operator who drives and operates the cockpit 3 provided above the traveling undercarriage 2 uses the engine 4 provided below the cockpit 3 to perform the harvesting operation. The harvester is started by running the combine, and the reaping culm is cut by the front reaper 10. The reaping culm is transferred to the upper rear part by the reaper 10 and supplied to the threshing machine. During the pinch transfer, threshing is performed, and the threshed and sorted kernels are temporarily stored in the combine.

During the harvesting operation, the hot air generated from the engine 4 is discharged from an exhaust port 6 for discharging the hot air provided below a horizontal partition plate 5 provided on one side of the engine 4. The hot air is exhausted and guided rearward by a hot air guide plate 7 provided above the air outlet 6 to be exhausted.

A part of the hot air exhausted from the air outlet 6 is guided by a guide guide plate 20 provided on the hot air guide plate 7.
The air is guided backward and discharged so as not to come into contact with the reaping input pulley 19a that drives the reaper 10.
