又，由於將排氣淨化裝置(40)配置在設置於穀槽(6)底部的傾斜壁(23B)下方之空間，因此藉由來自該排氣淨化裝置(40)的放熱，促進穀槽(6)儲存的穀粒之乾燥，使得穀粒排出時穀槽內部不易產生穀粒堵塞。 Further, since the exhaust gas purifying device (40) is disposed in a space below the inclined wall (23B) provided at the bottom of the trough (6), the trough is promoted by the heat release from the exhaust gas purifying device (40) ( 6) The dried grain is stored so that the grain inside is not easily clogged in the trough when the grain is discharged.

又，由於與排氣淨化裝置(40)的流出口連接的排氣管(61)係沿著揚穀裝置(14)向上方延伸設置，因此即使排氣氣體從排氣管(61)的上端部排出，該高溫排氣氣體亦不易向著容易堆積在機體下部的稻屑。 Further, since the exhaust pipe (61) connected to the outflow port of the exhaust gas purifying device (40) extends upward along the vane device (14), even if the exhaust gas is from the upper end of the exhaust pipe (61) When the part is discharged, the high-temperature exhaust gas is not easily directed to the rice dust which is likely to accumulate in the lower portion of the body.

如請求項2所記載的發明，除了請求項1所記載的發明之效果以外，由於將排氣管(61)的上端部配置在比穀槽(6)的上面還高之位置，因此能使從該排氣管(61)的上端部排出之排氣氣體的排出方向，不受穀槽(6)的側壁限制，可任意地設定，且能使該高溫排氣氣體不易觸及穀槽的側壁。 According to the invention of claim 2, in addition to the effect of the invention described in claim 1, the upper end portion of the exhaust pipe (61) is disposed at a position higher than the upper surface of the trough (6). The discharge direction of the exhaust gas discharged from the upper end portion of the exhaust pipe (61) is not limited by the side wall of the trough (6), and can be arbitrarily set, and the high-temperature exhaust gas can be prevented from reaching the side wall of the trough. .

如請求項3所記載的發明，除了請求項2所記載的發明之效果以外，由於使排氣管(61)的下部沿著形成在穀槽(6)的底部之傾斜壁(23B)的下面且朝斜上方延伸設置，因此即使於排氣淨化裝置(40)的流入口向上之狀態下，仍能讓該排氣淨化裝置(40)大幅度地伸入傾斜壁(23B)下方之空間。 According to the invention of claim 3, in addition to the effect of the invention described in claim 2, the lower portion of the exhaust pipe (61) is formed below the inclined wall (23B) formed at the bottom of the trough (6). Further, it is extended obliquely upward, so that even in the state where the inflow port of the exhaust gas purifying device (40) is upward, the exhaust gas purifying device (40) can be largely extended into the space below the inclined wall (23B).

如請求項4所記載的發明，除了請求項3所記載的發明之效果以外，由於排氣管(61)係由下部的第1排氣管(61A)和上部的第2排氣管(61B)構成，該下部的第1排氣管(61A)係連接排氣淨化裝置(40)的流出口，該 上部的第2排氣管(61B)係連通該第1排氣管(61A)的上端部，並使第1排氣管(61A)沿著傾斜壁(23B)的下面，因此藉由一方面將排氣淨化裝置(40)配置在穀槽(6)底部的傾斜壁(23B)下方之空間，一方面保持第1排氣管(61A)的形狀，而使該第1排氣管(61A)能與沿著揚穀裝置(14)的第2排氣管(61B)連通。 According to the invention of claim 4, in addition to the effects of the invention described in claim 3, the exhaust pipe (61) is composed of a lower first exhaust pipe (61A) and an upper second exhaust pipe (61B). The first exhaust pipe (61A) of the lower portion is connected to the outlet of the exhaust gas purification device (40). The upper second exhaust pipe (61B) communicates with the upper end portion of the first exhaust pipe (61A), and the first exhaust pipe (61A) is along the lower surface of the inclined wall (23B). The exhaust gas purifying device (40) is disposed in a space below the inclined wall (23B) at the bottom of the trough (6), and maintains the shape of the first exhaust pipe (61A) to make the first exhaust pipe (61A) ) can communicate with the second exhaust pipe (61B) along the lifter device (14).

如請求項5所記載的發明，除了上述請求項4所記載的發明之效果以外，由於構成為使第2排氣管(61B)下端部的內徑形成比第1排氣管(61A)上端部的外徑還大，且於第1排氣管(61A)的上端部***於第2排氣管(61B)的下端部之狀態下，在第1排氣管(61A)上端部的外周面和第2排氣管(61B)下端部的內周面之間形成有預定的間隙，因此即使排氣淨化裝置(40)所連接的第1排氣管(61A)，與沿著揚穀裝置(14)設置的上部第2排氣管(61B)彼此產生不同的振動，亦不易對排氣淨化裝置(40)和第1排氣管(61A)的連接部分等重複施加應力，因而排氣管路不易產生金屬疲勞而能提升持久性。 According to the invention of claim 5, in addition to the effects of the invention described in claim 4, the inner diameter of the lower end portion of the second exhaust pipe (61B) is formed to be higher than the upper end of the first exhaust pipe (61A). The outer diameter of the upper end portion of the first exhaust pipe (61A) is inserted into the lower end portion of the second exhaust pipe (61B) in the state where the upper end portion of the first exhaust pipe (61A) is inserted. A predetermined gap is formed between the surface and the inner circumferential surface of the lower end portion of the second exhaust pipe (61B). Therefore, even the first exhaust pipe (61A) connected to the exhaust gas purification device (40) is along the Yanggu Valley. The upper second exhaust pipe (61B) provided in the device (14) generates different vibrations from each other, and it is also difficult to repeatedly apply stress to the connection portion of the exhaust gas purifying device (40) and the first exhaust pipe (61A), and thus the row is discharged. The gas line is less prone to metal fatigue and improves durability.

又，藉由該第1排氣管(61A)上端部的外周面和第2排氣管(61B)下端部的內周面之間所形成的間隙之擴散器效果而吸入外氣，能使通過第2排氣管(61B)內的排氣氣體的溫度下降，且能從該間隙將從第2排氣管(61B)上端部的排氣口浸入的雨水等排出至外部。 Moreover, the outside air is taken in by the diffuser effect of the gap formed between the outer peripheral surface of the upper end portion of the first exhaust pipe (61A) and the inner peripheral surface of the lower end portion of the second exhaust pipe (61B). The temperature of the exhaust gas in the second exhaust pipe (61B) is lowered, and rainwater or the like that is infiltrated from the exhaust port at the upper end portion of the second exhaust pipe (61B) can be discharged to the outside.

如請求項6所記載的發明，除了請求項1至5中任一項所記載的發明之效果以外，由於在排氣管(61)的上端 部配置導引管帽(62)，該管帽(62)係用以橫向導引從該排氣管(61)的上端部向上排出的氣體，因此能防止雨水等浸入排氣管(61)。 The invention according to claim 6 is, in addition to the effects of the invention described in any one of claims 1 to 5, at the upper end of the exhaust pipe (61). The guiding tube cap (62) is configured to laterally guide the gas discharged upward from the upper end portion of the exhaust pipe (61), thereby preventing rainwater or the like from being immersed in the exhaust pipe (61) .

如請求項7所記載的發明，除了上述請求項6所記載的發明之效果以外，於平面觀看，由於將藉由管帽(62)導引的排氣氣體的排出方向，設定成沿著被收納於機體上收納位置之穀粒排出用的橫移送筒(8B)之方向，因此該高溫排氣氣體不易觸及橫移送筒(8B)，而能防止該橫移送筒(8B)之熱變形等。 According to the invention of claim 7, in addition to the effects of the invention described in the above claim 6, the discharge direction of the exhaust gas guided by the cap (62) is set to be along the plane. Since it is accommodated in the direction of the traverse feed cylinder (8B) for discharging the grain at the storage position on the machine body, the high-temperature exhaust gas does not easily touch the traverse feed cylinder (8B), and the thermal deformation of the traverse feed cylinder (8B) can be prevented. .

The unburned fuel is oxidized by the DOC 40A, and the granulated substance in the exhaust gas is removed by the filtering action of the DPF 40B.

如圖2等所示，為了簡化安裝構造，不透過安裝橡膠9a而將DPF組件40固定於機體框架2上。為了防止從引擎9排出的排氣氣體的溫度降低，將該DPF組件40配置於引擎9的近旁為佳，因此配置於引擎9的背面和第1揚穀裝置14的基部之間。又，構成為將DPF組件40的前端部配置於與穀槽6的前壁大致同一位置，促進穀槽6所儲存的穀粒之乾燥。 As shown in FIG. 2 and the like, in order to simplify the mounting structure, the DPF assembly 40 is fixed to the body frame 2 without the rubber 9a being attached. In order to prevent the temperature of the exhaust gas discharged from the engine 9 from decreasing, it is preferable to arrange the DPF assembly 40 in the vicinity of the engine 9, and therefore, it is disposed between the back surface of the engine 9 and the base of the first valley device 14. Moreover, the front end portion of the DPF assembly 40 is disposed at substantially the same position as the front wall of the trough 6, and the drying of the grain stored in the trough 6 is promoted.

如圖3、圖4所示，為了藉由來自DPF組件40的放熱使穀槽6內所儲存的穀粒乾燥，將DPF組件40配置於穀槽6左右方向的大致中央部分的下側，於平面觀看係配置於穀槽6底部的傾斜壁23B的輪廓的下側。DPF組件40的排氣口亦位於傾斜壁23B的下側。 As shown in FIGS. 3 and 4, in order to dry the grain stored in the trough 6 by the heat release from the DPF unit 40, the DPF unit 40 is disposed on the lower side of the substantially central portion of the trough 6 in the left-right direction. The plan view is disposed on the lower side of the outline of the inclined wall 23B at the bottom of the trough 6. The exhaust port of the DPF assembly 40 is also located on the lower side of the inclined wall 23B.

如圖2所示，DPF組件40的吸氣口係透過連接管50 而連接於排氣歧管30B，DPF組件40的排氣口連接著排氣管60，其係用以將經除去雜質等的排氣氣體排出至外部。 As shown in FIG. 2, the suction port of the DPF assembly 40 is transmitted through the connecting pipe 50. Connected to the exhaust manifold 30B, the exhaust port of the DPF assembly 40 is connected to the exhaust pipe 60 for exhausting exhaust gas from which impurities or the like are removed to the outside.

連接管50係由鋼管構成的第1連接管51、不鏽鋼管構成的可撓管52、以及鋼管構成的第2連接管53所構成，該可撓管52具有能降低引擎9的振動傳播的可撓性。亦可以橡膠等具有可撓性的素材形成該連接管50全體或可撓管52。 The connecting pipe 50 is composed of a first connecting pipe 51 made of a steel pipe, a flexible pipe 52 made of a stainless steel pipe, and a second connecting pipe 53 made of a steel pipe. The flexible pipe 52 has a function of reducing vibration transmission of the engine 9. flexibility. The entire connecting tube 50 or the flexible tube 52 may be formed of a flexible material such as rubber.

於引擎9啟動時和機體行走時，即使該引擎9和DPF組件40產生彼此不同的振動，仍能減少對於DPF組件40的吸氣口和連接管50的連接部分、及連接管50和排氣歧管30B的連接部分等所施加之應力，使得排氣流入側的管路不易產生金屬疲勞而提升持久性。 When the engine 9 is started and the body is traveling, even if the engine 9 and the DPF assembly 40 generate different vibrations from each other, the connection portion to the suction port and the connecting pipe 50 of the DPF assembly 40, and the connecting pipe 50 and the exhaust pipe can be reduced. The stress applied by the connecting portion of the manifold 30B or the like makes the pipe on the exhaust gas inflow side less likely to cause metal fatigue and enhance durability.

如圖2所示，於側面觀看時，第1連接管51係從排氣歧管30向大致下側延伸，可撓管52係從第1連接管51的前端部向大致下側延伸，第2連接管53係從可撓管52的前端部彎曲大致90度後，朝後方延伸而連接於DPF組件40的吸氣口。 As shown in FIG. 2, when viewed from the side, the first connecting pipe 51 extends substantially downward from the exhaust manifold 30, and the flexible pipe 52 extends from the front end portion of the first connecting pipe 51 to the lower side. The connecting pipe 53 is bent from the front end portion of the flexible pipe 52 by substantially 90 degrees, and then extends rearward to be connected to the intake port of the DPF assembly 40.

於背面觀看時，第1連接管51係從排氣歧管30彎曲大致90度後，朝下方延伸，可撓管52係從第1連接管51的前端部向下方延伸，第2連接管53係從可撓管52的前端部向下方延伸後，向後方彎曲大致90度，連接於DPF組件40的吸氣口。 When viewed from the back side, the first connecting pipe 51 is bent downward by approximately 90 degrees from the exhaust manifold 30, and extends downward, and the flexible pipe 52 extends downward from the front end portion of the first connecting pipe 51, and the second connecting pipe 53 is extended downward. After extending downward from the front end portion of the flexible tube 52, it is bent rearward by substantially 90 degrees and connected to the intake port of the DPF assembly 40.

排氣管60係由鋼管構成的排氣管(tape pipe，帶狀管)61及管帽62所構成，該管帽62係形成為彎曲形狀或折曲 形狀用以防止雨水等浸入排氣管61。 The exhaust pipe 60 is composed of a duct pipe 61 and a pipe cap 62 which are formed of a steel pipe, and the cap 62 is formed into a curved shape or a bent shape. The shape is for preventing rainwater or the like from entering the exhaust pipe 61.

於側面觀看時，排氣管61的基部(排氣管61的下部)係從DPF組件40的排氣口(申請專利範圍中的流出口)向上側延伸後，沿著具有段差的傾斜壁23B中較高側的傾斜壁23B的下面而向左側前方上方傾斜延伸。排氣管61的上部係從排氣管61基部的前端部朝前方上升且急傾斜延伸，管帽62係於形成在排氣管61上端部的排氣口之上側，將開口部62A向後方安裝。管帽62係於排氣管61的上端部透過撐桿安裝之構造，但也可以是安裝於第1揚穀裝置14的上端部之構造。管帽62係縱剖面形狀形成為半圓弧狀，該管帽62的基部(下部)形成為筒狀，該筒狀部的內徑形成為比排氣管61上端部的外徑還大。藉由將管帽62被覆安裝於排氣管61的上端部，使該管帽62外側的管帽體的下部之內周面和排氣管61上端部的外周面之間形成預定的間隙。於該間隙，藉由來自排氣管61上端部而朝管帽62側排出的排氣氣體之流動而產生擴散器效果，吸入外氣，使從開口部62A排出之排氣氣體的溫度更為降低。 When viewed from the side, the base of the exhaust pipe 61 (the lower portion of the exhaust pipe 61) extends upward from the exhaust port of the DPF assembly 40 (the outflow port in the patent application), along the inclined wall 23B having the step The lower side of the inclined wall 23B on the upper side of the middle side is inclined obliquely upward toward the front side of the left side. The upper portion of the exhaust pipe 61 rises forward from the front end portion of the base portion of the exhaust pipe 61 and extends obliquely. The cap 62 is attached to the upper side of the exhaust port formed at the upper end portion of the exhaust pipe 61, and the opening portion 62A is rearward. installation. The cap 62 is attached to the upper end portion of the exhaust pipe 61 through the strut, but may be attached to the upper end portion of the first pan throttling device 14. The cap 62 has a semi-circular shape in a longitudinal cross-sectional shape, and a base portion (lower portion) of the cap 62 is formed in a tubular shape, and an inner diameter of the tubular portion is formed to be larger than an outer diameter of an upper end portion of the exhaust pipe 61. By attaching the cap 62 to the upper end portion of the exhaust pipe 61, a predetermined gap is formed between the inner peripheral surface of the lower portion of the cap body outside the cap 62 and the outer peripheral surface of the upper end portion of the exhaust pipe 61. In this gap, the diffuser effect is generated by the flow of the exhaust gas discharged from the upper end portion of the exhaust pipe 61 toward the cap 62 side, and the outside air is taken in, so that the temperature of the exhaust gas discharged from the opening portion 62A is further increased. reduce.

如圖2、圖11所示，為了有效地活用脫穀裝置5和穀槽6之間所形成的空間S，於被形成在配置第1揚穀裝置14的穀槽6的垂直壁23A之上下方向的凹部22A，排氣管61的上部以與第1揚穀裝置14平行的姿勢被配置在該第1揚穀裝置14的前方。排氣管61的上部係透過撐桿而被支撐在第1揚穀裝置14。如此，藉由將高溫狀態的排氣管60的上部配置於穀槽6的垂直壁23A的凹部22A，能促進穀 槽6所儲存的穀粒之乾燥，以良好的能率進行穀粒搬運。 As shown in Fig. 2 and Fig. 11, in order to effectively utilize the space S formed between the threshing apparatus 5 and the trough 6, it is formed above the vertical wall 23A of the trough 6 in which the first valley device 14 is disposed. The concave portion 22A in the direction, the upper portion of the exhaust pipe 61 is disposed in front of the first valley device 14 in a posture parallel to the first panning device 14. The upper portion of the exhaust pipe 61 is supported by the first valley device 14 through the stay. By arranging the upper portion of the exhaust pipe 60 in the high temperature state in the concave portion 22A of the vertical wall 23A of the trough 6, the valley can be promoted. The grain stored in the tank 6 is dried, and the grain is transported at a good energy rate.

為了防止從排氣管61被排出至機外的排氣氣體被預淨化器32吸氣，而將管帽62的開口部62A之上下方向的中心位置，配置於比預淨化器32的吸氣口還高的位置。此外，將形成在排氣管61上部的上端部之排氣口配置在比預淨化器32的吸氣口還高的位置更佳。 In order to prevent the exhaust gas discharged from the exhaust pipe 61 to the outside of the engine from being sucked by the prepurifier 32, the center position of the opening 62A of the cap 62 in the vertical direction is disposed in the suction of the prepurifier 32. The mouth is still high. Further, it is preferable that the exhaust port formed at the upper end portion of the upper portion of the exhaust pipe 61 is disposed at a position higher than the intake port of the prepurifier 32.

又，如圖3所示，為了以良好的能率將排氣氣體排出至機外，來自管帽62的開口部62A之排氣氣體的排出導引方向，係設定成在卸榖螺旋機8的橫移送管(橫移送筒)8B處於聯合收割機的機體上的收納狀態之狀態下，與該橫移送管8B大致平行。 Further, as shown in FIG. 3, in order to discharge the exhaust gas to the outside of the machine at a good energy rate, the discharge guide direction of the exhaust gas from the opening portion 62A of the cap 62 is set to be at the unloading screw machine 8. The traverse feed pipe (traverse transfer cylinder) 8B is substantially parallel to the traverse feed pipe 8B in a state of being stored in the body of the combine harvester.

為了有效地活用脫穀裝置5和穀槽6之間所形成的空間S，排氣管61的基部係配置於藉由穀槽6的傾斜壁23B的段差所形成之凹部22B內，排氣管61的上部係於配置有第1揚穀裝置14的穀槽6的垂直壁23A之凹部22A，與第1揚穀裝置14的前側並列配置。 In order to effectively utilize the space S formed between the threshing apparatus 5 and the trough 6, the base of the exhaust pipe 61 is disposed in the recess 22B formed by the step of the inclined wall 23B of the trough 6, the exhaust pipe The upper portion of the 61 is a recess 22A in which the vertical wall 23A of the trough 6 of the first valley device 14 is disposed, and is arranged in parallel with the front side of the first panning device 14.

亦可以DPF組件40的排氣口的外徑為基準，將排氣管61的基部的內徑形成為大徑。藉此能得到擴散器效果，因為從DPF組件40被排出至排氣管61的排氣氣體的流出，而從DPF組件40和排氣管61的基部的間隙吸入空氣，使排氣管61內的排氣氣體的溫度降低，且亦能從該間隙將從管帽62的開口部62A浸入進來的雨水等排水至機外。又，能將DPF組件40周邊的高溫雰圍氣體吸出至機外，防止設置在DPF組件40周邊的感測器類之故障。 The inner diameter of the base of the exhaust pipe 61 may be formed to have a large diameter based on the outer diameter of the exhaust port of the DPF assembly 40. Thereby, the diffuser effect can be obtained because the outflow of the exhaust gas discharged from the DPF assembly 40 to the exhaust pipe 61, and the air is taken in from the gap between the base portions of the DPF assembly 40 and the exhaust pipe 61, so that the exhaust pipe 61 is inside. The temperature of the exhaust gas is lowered, and it is also possible to drain rainwater or the like that has entered the opening 62A of the cap 62 from the gap to the outside of the machine. Further, the high-temperature atmosphere around the DPF assembly 40 can be sucked out of the machine to prevent malfunction of the sensors provided around the DPF assembly 40.

(排氣管之其他實施例) (Other embodiments of the exhaust pipe)

如圖5所示，亦可將前述排氣管61，藉由鋼管構成的下部之排氣管(申請專利範圍中的第1排氣管)61A，及較該排氣管61A更大徑的鋼管構成的上部之排氣管(申請專利範圍中的第2排氣管)61B構成。 As shown in FIG. 5, the exhaust pipe 61 may be a lower exhaust pipe (a first exhaust pipe in the patent application) 61A composed of a steel pipe, and a larger diameter than the exhaust pipe 61A. The upper exhaust pipe (the second exhaust pipe in the patent application) 61B composed of a steel pipe is configured.

於側面觀看時，下部的排氣管61A係從DPF組件40的排氣口向上側延伸後，朝前方上側傾斜延伸。上部的排氣管61B係從排氣管61A的上端部向前方上側，比排氣管61A更急傾斜延伸，形成於排氣管61B上端部的排氣口安裝有上述管帽62。 When viewed from the side, the lower exhaust pipe 61A extends upward from the exhaust port of the DPF assembly 40, and then extends obliquely toward the upper front side. The upper exhaust pipe 61B extends from the upper end portion of the exhaust pipe 61A toward the upper side, and extends more obliquely than the exhaust pipe 61A, and the cap 62 is attached to the exhaust port formed at the upper end portion of the exhaust pipe 61B.

為了有效地活用脫穀裝置5和穀槽6之間所形成的空間S，上部的排氣管61B被配置在形成於配置第1揚穀裝置14的穀槽6的垂直壁23A之凹部22A，且以與第1揚穀裝置14平行的姿勢被配置在第1揚穀裝置14的前方 In order to effectively utilize the space S formed between the threshing apparatus 5 and the trough 6, the upper exhaust pipe 61B is disposed in the recess 22A formed in the vertical wall 23A of the trough 6 in which the first valley device 14 is disposed, And disposed in front of the first valley device 14 in a posture parallel to the first valley device 14

為了防止從排氣管61B的上端部被排出至機外的排氣氣體被預淨化器32吸氣，管帽62係將管帽62的開口部62A之上下方向的中心位置，配置於比預淨化器32的吸氣口32A還高的位置。且，為了以良好的能率將排氣氣體排出至機外，管帽62的排氣氣體的排出導引方向，係設定成與處於收納狀態的卸榖螺旋機8的橫移送管8B呈大致平行。 In order to prevent the exhaust gas discharged to the outside of the exhaust pipe from the upper end portion of the exhaust pipe 61B from being sucked by the prepurifier 32, the cap 62 is disposed at a center position in the upper and lower directions of the opening 62A of the cap 62. The suction port 32A of the purifier 32 is also in a high position. Further, in order to discharge the exhaust gas to the outside of the machine at a good energy rate, the discharge guide direction of the exhaust gas of the cap 62 is set to be substantially parallel to the traverse feed pipe 8B of the unloading screw machine 8 in the accommodated state. .

圖示省略，但於背面視時，下部的排氣管61A係於從DPF組件40的排氣口向上側延伸後，朝左上側傾斜延伸，上部的排氣管61B係從下部的排氣管61A的上端部向前側 上方延伸，且於形成在排氣管61B上端部的排氣口安裝有上述管帽62。 Although not shown in the figure, the lower exhaust pipe 61A extends obliquely upward from the exhaust port of the DPF assembly 40 in the rear view, and extends obliquely toward the upper left side, and the upper exhaust pipe 61B is exhausted from the lower exhaust pipe. The upper end of the 61A is on the front side The above-mentioned cap 62 is attached to the exhaust port formed at the upper end portion of the exhaust pipe 61B.

為了有效地活用脫穀裝置5和穀槽6之間所形成的空間S，下部的排氣管61A係配置於穀槽6的傾斜壁23B之凹部22B內，上部的排氣管61B係於配置有第1揚穀裝置14的穀槽6的垂直壁23A之凹部22A內，與第1揚穀裝置14並列配置。 In order to effectively utilize the space S formed between the threshing apparatus 5 and the trough 6, the lower exhaust pipe 61A is disposed in the recess 22B of the inclined wall 23B of the trough 6, and the upper exhaust pipe 61B is disposed. The recessed portion 22A of the vertical wall 23A of the trough 6 of the first valley device 14 is arranged in parallel with the first valley device 14.

上部的排氣管61B下端部的內徑係形成為比下部的排氣管61A上端部的外徑還大徑。於將排氣管61A的上端部***排氣管61B的下端部之狀態下，在排氣管61A上端部的外周面和排氣管61B下端部的內周面之間形成預定的間隙。因此，藉由從排氣管61A被排出至排氣管61B的排氣氣體之流出，能從排氣管61A和排氣管61B的間隙吸入外氣，使排氣管61B內的排氣氣體之溫度降低。又，亦能從該間隙將從管帽62的開口部62A浸入進來的雨水等排水至機外。又，能將DPF組件40周邊的高溫雰圍氣體吸出至機外，防止設置在DPF組件40周邊的感測器類之故障。又，DPF組件40所連接之下部的排氣管61A和沿著第1揚穀裝置14設置之上部的排氣管61B，即使彼此產生不同的振動，亦不易對DPF組件40和排氣管61A的連接部分等重複施加應力，使得排氣管路不易產生金屬疲勞而提升持久性。此外，為了防止稻草等雜質進入排氣管61B內，在排氣管61A和排氣管61B的間隙張設網子為佳。 The inner diameter of the lower end portion of the upper exhaust pipe 61B is formed to be larger than the outer diameter of the upper end portion of the lower exhaust pipe 61A.

Therefore, by the outflow of the exhaust gas discharged from the exhaust pipe 61A to the exhaust pipe 61B, the outside air can be taken in from the gap between the exhaust pipe 61A and the exhaust pipe 61B, and the exhaust gas in the exhaust pipe 61B can be made. The temperature is lowered. Moreover, it is also possible to drain rainwater or the like that has entered the opening 62A of the cap 62 from the gap to the outside of the machine. Further, the high-temperature atmosphere around the DPF assembly 40 can be sucked out of the machine to prevent malfunction of the sensors provided around the DPF assembly 40. Further, the exhaust pipe 61A connected to the lower portion of the DPF assembly 40 and the exhaust pipe 61B disposed along the upper portion of the first valley device 14 are not easily attached to the DPF assembly 40 and the exhaust pipe 61A even if different vibrations are generated from each other. Repeated stress is applied to the connecting portion and the like, so that the exhaust pipe is less prone to metal fatigue and enhances durability. Further, in order to prevent impurities such as straw from entering the exhaust pipe 61B, it is preferable to form a mesh in the gap between the exhaust pipe 61A and the exhaust pipe 61B.
