Thus, the engine 11 is started, the threshing device 3 and the mowing device 4 are driven by the rotation of the engine 11, and the traveling device 2 is driven to run and perform mowing and threshing work. The driving force obtained by burning the supplied fuel is transmitted to each unit, and the burned fuel is purified as exhaust gas by the DPF 16 and the SCR 17 of the exhaust gas purification device 15 provided in the exhaust device 12 and discharged outside the machine.

The exhaust gas purification device 15 adds a soluble organic component in PM contained in the exhaust gas of the diesel engine 11, a DPF 16 for oxidizing CO and HC, and urea water to the exhaust gas to generate ammonia. It is composed of SCR17 which reacts with an oxide to convert nitrogen and water.
The exhaust gas purification device 15 is located between the engine 11 and a grain elevator 20 that supplies grains from the threshing device 3 to the Glen tank 5, which is disposed on the rear side of the engine 11.

The portion 24 is placed horizontally.
Therefore, the tail pipe 22 can be arranged at a high position of the fuselage, and the accumulation of deposits such as straw waste on the tail pipe 22 is suppressed.

That is, since straw dust, soil, dust, and the like leak from the bottom of the threshing device 3 or particularly from the bottom of the grain elevator 20, a tail is formed near the upper surface of the body frame 1 or the lower surface of the body frame 1 as in the related art. In the case where the pipe 22 is disposed, straw chips, soil, dust, and the like leaking from the bottom of the threshing device 3 or the bottom of the grain elevator 20 are likely to accumulate on the tail pipe 22, but the present invention prevents this. I do.

  When the beans are harvested, a part of the second reduction device 33 is provided with a part that can be opened, and soil, dust, and the like can be discharged from the opened part. Between the suction port 41 and the second reduction device 33 because the supply module 35 is provided with a gap between the suction port 41 and the second reduction device 33. Due to the presence of the provided supply module 35, the Karin suction port 41 preferentially sucks the air blown from the radiator cooling fan 40, and the supply module 35 is provided with a gap between it and the side plate of the threshing device 3. Therefore, the traveling wind flows toward the second reduction device 33 from this gap, and the accumulation of dust and the like leaking from the second reduction device 33 can be suppressed.

  The exhaust gas purification device 15 is provided with the DPF 16 and the SCR 17 mounted on a mounting table 53 of a purification device support frame 45 provided on the body frame 1, a cover mounting frame 46 is provided on the purification device support frame 45, Since the cover 47 is detachably attached to the frame 46, the cover 47 prevents accumulation of straw chips and the like on the DPF 16 and the SCR 17 of the exhaust gas purification device 15.
