The exhaust gas purifying case 62 is connected to the exhaust manifold 112 via the exhaust pipe 113 and the exhaust connection pipe 115. [ 15, a space formed between the left side surface of the engine room frame 91 and the right side surface of the threshing device 5 in the right side of the rear portion of the threshing device 5 has a long cylindrical shape (lateral laying posture) The exhaust gas purifying case 62 is disposed. The exhaust gas of the diesel engine 14 is introduced into the exhaust gas purifying case 62 through the exhaust manifold 112, the supercharger 113, and the exhaust connection pipe 115.

Therefore, the difference between the exhaust gas pressure on the inflow side of the soot filter 66 and the exhaust gas pressure on the outflow side of the soot filter 66 (the differential pressure of the exhaust gas) is detected through the differential pressure sensor 122. Since the residual amount of the particulate matter in the exhaust gas collected in the particulate filter 66 is proportional to the differential pressure of the exhaust gas, when the amount of the particulate matter remaining in the particulate filter 66 increases more than a predetermined amount, A regeneration control (for example, control for raising the exhaust temperature) or an alarm display for reducing the particulate matter amount of the particulate filter 66 is performed based on the detection result.
An upstream side gas temperature sensor 128 for detecting the exhaust temperature on the exhaust gas introduction side of the diesel oxidation catalyst 76 and a downstream side gas temperature sensor 128 for detecting the exhaust temperature on the exhaust gas exhaust side of the diesel oxidation catalyst 65 And the electric wiring connector 129 of the upstream side gas temperature sensor 128 and the electric wiring connector 131 of the downstream side gas temperature sensor 130 are fixed to the sensor bracket 124.

[ Therefore, the exhaust gas purifying device 61 can be mounted at a high position of the engine room frame 91 through the hanging fixture 395. The installation space of the exhaust gas purification device 61 can be easily secured and the volume of the engine room 92 or the exhaust gas purification device 61 is not limited. Further, the exhaust gas purifying device 61 can be supported with a simple attachment structure within a range where the temperature of the exhaust gas supplied to the exhaust gas purifying device 61 does not decrease (the self regenerating ability is not reduced). In addition, when the diesel engine 14 is stopped, it is possible to reduce the adverse effect that the vicinity of the heat radiation path of the exhaust gas purifier 61 becomes high.

[ Therefore, the exhaust gas purifier 61 can be compactly supported by utilizing the dead space formed between the installation portion of the diesel engine 14 and the threshing device 5 adjacent thereto. The exhaust gas purifying device 61 can be configured to be surrounded by the mounting portion of the diesel engine 14 and the threshing device 5 so that the operator or the like can easily be prevented from coming into contact with the exhaust gas purifying device 61, And the temperature of the exhaust gas purifying device 61 can be quickly lowered when the diesel engine 14 is stopped, for example, by exposing the exhaust gas purifying device 61 to the outside of the gas.
As shown in Figs. 15 to 18, between the upper surface of the base body on the engine room 92 side where the diesel engine 14 is installed and the upper surface of the base body on the side of the threshing device 5 adjacent to the diesel engine 14 mounting portion And the exhaust gas purifying device 61 is disposed through the fixture 395. [ Therefore, it is possible to constitute the exhaust gas purifying device 61 so that one side of the exhaust gas purifying device 61 is opened toward the upper surface side of the threshing device 5, and the exhaust gas purifying device 61 can be formed. It is possible to maintain the temperature of the exhaust gas purifier 61 during the operation of the diesel engine 14 to be higher than necessary to maintain the self regenerative capability of the exhaust gas purifier 61. When the diesel engine 14 is stopped The temperature of the exhaust gas purifying device 61 can be lowered in a short time. The exhaust heat of the exhaust gas purifying device 61 can reduce the occurrence of problems such as the heating of surrounding components.
