One end side of the exhaust connection pipe 115 is connected to the purification inlet pipe 86 via a bendable bellows-like exhaust pipe 114, while the other end side of the exhaust connection pipe 115 is connected to the exhaust outlet pipe 116 of the supercharger 113. ing.
　上記の構成により、排気マニホールド１１２に過給機１１３と排気連結管１１５などを介して排気ガス浄化ケース６２が連通接続される。図４に示す如く、脱穀装置５後部の右側方において、脱穀装置５右側面寄りのエンジンルームフレーム９１上面側に形成されるスペースに、前後方向に長い円筒形状（横置き姿勢）の排気ガス浄化ケース６２が配置される。排気マニホールド１１２、過給機１１３、排気出口管１１６、排気連結管１１５、蛇腹状排気管１１４を介して、ディーゼルエンジン１４の排気ガスが排気ガス浄化ケース６２の入口側ケース６３内に導入される。ディーゼルエンジン１４の排気ガスは、排気ガス浄化ケース６２前部のディーゼル酸化触媒６５から、排気ガス浄化ケース６２後部のスートフィルタ６６に移動して、脱穀装置５（エンジンルーム９２）の後側方に向けてテールパイプ８３から大気中に放出される。 With the above configuration, the exhaust gas purification case 62 is connected to the exhaust manifold 112 via the supercharger 113 and the exhaust connection pipe 115. As shown in FIG. 4, in the right side of the rear part of the threshing device 5, the exhaust gas purification having a cylindrical shape (horizontal posture) long in the front-rear direction is formed in the space formed on the upper surface side of the engine room frame 91 near the right side surface of the threshing device 5. A case 62 is disposed. The exhaust gas of the diesel engine 14 is introduced into the inlet side case 63 of the exhaust gas purification case 62 through the exhaust manifold 112, the supercharger 113, the exhaust outlet pipe 116, the exhaust connection pipe 115, and the bellows-like exhaust pipe 114. . The exhaust gas of the diesel engine 14 moves from the diesel oxidation catalyst 65 at the front part of the exhaust gas purification case 62 to the soot filter 66 at the rear part of the exhaust gas purification case 62, and to the rear side of the threshing device 5 (engine room 92).

That is, the upper surface height of the exhaust gas purification case 62 is made lower than the height of the lower surface of the exhaust auger 8, and the lower surface height of the exhaust gas purification case 62 is made higher than the height of the upper surface of the threshing device 5. The exhaust gas purification case 62 is supported at a position lower than the bottom surface of the discharge auger 8 in the storage position (harvesting work posture). Therefore, even if the discharge auger 8 moves to either the storage position or the grain discharge position on the outer side of the machine, the discharge auger 8 does not collide with the exhaust gas purification case 62 and the like. In the discharge operation, the discharge auger 8 can be easily swung and moved outside the machine body.
　一方、図４、図７に示す如く、排気ガス浄化装置６１の前面側と後面側に前後の吊下げ金具体１２１，１２２をそれぞれ設けている。したがって、前記コンバインの組立工場などにおいて、例えばチェンブロックまたはホイストなどの荷役吊下げ装置のフックに吊下げ金具体１２１，１２２を係止させ、前記チェンブロックなどに吊下げ金具体１２１，１２２を介して排気ガス浄化装置６１を吊下げることができ、重い排気ガス浄化装置６１の組付けまたは取外し等の作業を簡単に実行できる。なお、排気ガス浄化ケース６２の後端側にテールパイプ８３を連結するための厚板状後端フランジ体１２３に、吊下げ金具体１２２を一体的に形成している。 On the other hand, as shown in FIGS. 4 and 7, front and rear hanging metal parts 121 and 122 are provided on the front side and the rear side of the exhaust gas purification device 61, respectively. Therefore, in the assembly factory of the combine, for example, the hanging metal parts 121 and 122 are locked to the hooks of a cargo handling hanging device such as a chain block or a hoist, and the hanging metal parts 121 and 122 are connected to the chain block and the like. Thus, the exhaust gas purification device 61 can be suspended, and operations such as assembly or removal of the heavy exhaust gas purification device 61 can be easily performed. In addition, a hanging metal plate 122 is integrally formed on a thick plate-like rear end flange body 123 for connecting the tail pipe 83 to the rear end side of the exhaust gas purification case 62.

As described above, the cylindrical exhaust gas purification case 62 is fixedly mounted on the left upper frame 94 or the horizontal rail frame 95 in a horizontal posture (front-rear posture).
　また、エンジンルーム９２上側面のうち、脱穀装置５（作業部）寄りの上側面に排気ガス浄化装置６１の設置部（左側上面フレーム９４、横桟フレーム９５）を形成し、左側上面フレーム９４及び横桟フレーム９５の上面側に、支持枠体９６（上置き固定具）を介して、エンジンルーム９２の上方側から排気ガス浄化装置６１を組付けるように構成している。 Further, an installation part (left upper surface frame 94, horizontal rail frame 95) of the exhaust gas purifying device 61 is formed on the upper side surface of the engine room 92 near the threshing device 5 (working unit), and the left upper surface frame 94 and The exhaust gas purifying device 61 is assembled from the upper side of the engine room 92 to the upper surface side of the horizontal rail frame 95 via a support frame body 96 (upper fixture).
　また、厚板状後端フランジ体１２３にセンサブラケット１２４をボルト締結して、排気ガス浄化ケース６２後端側の出口側ケース７７の上面側にセンサブラケット１２４を突設する。排気ガス浄化ケース６２後端部の上面側にセンサブラケット１２４を配置させる。電気配線コネクタを一体的に設けた差圧センサ１２５が、センサブラケット１２４の平坦な上面に取付けられる。排気ガス浄化ケース６２の外側面にセンサブラケット１２４を介して差圧センサ１２５が配置される。 Also, the sensor bracket 124 is bolted to the thick plate-like rear end flange body 123, and the sensor bracket 124 is projected from the upper surface side of the outlet side case 77 on the rear end side of the exhaust gas purification case 62. The sensor bracket 124 is disposed on the upper surface side of the rear end portion of the exhaust gas purification case 62. A differential pressure sensor 125 integrally provided with an electrical wiring connector is attached to the flat upper surface of the sensor bracket 124. A differential pressure sensor 125 is disposed on the outer surface of the exhaust gas purification case 62 via a sensor bracket 124.
　なお、差圧センサ１２５には、図示しない上流側センサ配管と下流側センサ配管の一端側がそれぞれ接続される。排気ガス浄化ケース６２内のスートフィルタ６６を挟むように、排気ガス浄化ケース６２に配置された上流側と下流側の各センサ配管ボス体に、上流側と下流側の前記各センサ配管の他端側がそれぞれ接続される。 The differential pressure sensor 125 is connected to one end side of an upstream sensor pipe and a downstream sensor pipe (not shown). The upstream and downstream sensor pipe boss bodies disposed in the exhaust gas purification case 62 so as to sandwich the soot filter 66 in the exhaust gas purification case 62 are connected to the other ends of the upstream and downstream sensor pipes. Each side is connected.
　したがって、スートフィルタ６６の流入側の排気ガス圧力と、スートフィルタ６６の流出側の排気ガス圧力の差（排気ガスの差圧）が、差圧センサ１２２を介して検出される。スートフィルタ６６に捕集された排気ガス中の粒子状物質の残留量が排気ガスの差圧に比例するから、スートフィルタ６６に残留する粒子状物質の量が所定以上に増加したときに、差圧センサ１２５の検出結果に基づき、スートフィルタ６６の粒子状物質量を減少させる再生制御（例えば排気温度を上昇させる制御）または警報表示などが実行される。 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 (exhaust gas differential pressure) is detected via the differential pressure sensor 122. Since the residual amount of particulate matter in the exhaust gas collected by the soot filter 66 is proportional to the differential pressure of the exhaust gas, the difference occurs when the amount of particulate matter remaining in the soot filter 66 increases more than a predetermined amount. Based on the detection result of the pressure sensor 125, regeneration control for reducing the amount of particulate matter in the soot filter 66 (for example, control for increasing the exhaust temperature) or alarm display is executed.
　また、ディーゼル酸化触媒７６の排気ガス取入れ側の排気温度を検出する上流側ガス温度センサ１２８と、ディーゼル酸化触媒６５の排気ガス排出側の排気温度を検出する下流側ガス温度センサ１３０を備えると共に、上流側ガス温度センサ１２８の電気配線コネクタ１２９と、下流側ガス温度センサ１３０の電気配線コネクタ１３１を、センサブラケット１２４に固着する。排気ガス浄化ケース６２内部の排気温度の検出結果（各センサ１２８，１３０出力）に基づき、その適否または警報表示などが実行される。 In addition, an upstream gas temperature sensor 128 that detects the exhaust gas intake side temperature of the diesel oxidation catalyst 76 and a downstream gas temperature sensor 130 that detects the exhaust temperature of the diesel oxidation catalyst 65 on the exhaust gas discharge side are provided. The electrical wiring connector 129 of the upstream gas temperature sensor 128 and the electrical wiring connector 131 of the downstream gas temperature sensor 130 are fixed to the sensor bracket 124. Based on the detection result of the exhaust temperature inside the exhaust gas purification case 62 (outputs of the sensors 128 and 130), appropriateness or warning display is executed.

　なお、差圧センサ１２５には、図示しない上流側センサ配管と下流側センサ配管の一端側がそれぞれ接続される。排気ガス浄化ケース６２内のスートフィルタ６６を挟むように、排気ガス浄化ケース６２に配置された上流側と下流側の各センサ配管ボス体に、上流側と下流側の前記各センサ配管の他端側がそれぞれ接続される。 The differential pressure sensor 125 is connected to one end side of an upstream sensor pipe and a downstream sensor pipe (not shown). The upstream and downstream sensor pipe boss bodies disposed in the exhaust gas purification case 62 so as to sandwich the soot filter 66 in the exhaust gas purification case 62 are connected to the other ends of the upstream and downstream sensor pipes. Each side is connected.
　したがって、スートフィルタ６６の流入側の排気ガス圧力と、スートフィルタ６６の流出側の排気ガス圧力の差（排気ガスの差圧）が、差圧センサ１２２を介して検出される。スートフィルタ６６に捕集された排気ガス中の粒子状物質の残留量が排気ガスの差圧に比例するから、スートフィルタ６６に残留する粒子状物質の量が所定以上に増加したときに、差圧センサ１２５の検出結果に基づき、スートフィルタ６６の粒子状物質量を減少させる再生制御（例えば排気温度を上昇させる制御）または警報表示などが実行される。 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 (exhaust gas differential pressure) is detected via the differential pressure sensor 122. Since the residual amount of particulate matter in the exhaust gas collected by the soot filter 66 is proportional to the differential pressure of the exhaust gas, the difference occurs when the amount of particulate matter remaining in the soot filter 66 increases more than a predetermined amount. Based on the detection result of the pressure sensor 125, regeneration control for reducing the amount of particulate matter in the soot filter 66 (for example, control for increasing the exhaust temperature) or alarm display is executed.
　また、ディーゼル酸化触媒７６の排気ガス取入れ側の排気温度を検出する上流側ガス温度センサ１２８と、ディーゼル酸化触媒６５の排気ガス排出側の排気温度を検出する下流側ガス温度センサ１３０を備えると共に、上流側ガス温度センサ１２８の電気配線コネクタ１２９と、下流側ガス温度センサ１３０の電気配線コネクタ１３１を、センサブラケット１２４に固着する。排気ガス浄化ケース６２内部の排気温度の検出結果（各センサ１２８，１３０出力）に基づき、その適否または警報表示などが実行される。排気ガス浄化装置６１とセンサブラケット１２４の間が、支持枠体９６にて遮熱されるから、差圧センサ１２２またはコネクタ１２９，１３１の配線などを簡略化できる。その他の構成は図１～図７に示す第１実施形態と同様である。 In addition, an upstream gas temperature sensor 128 that detects the exhaust gas intake side temperature of the diesel oxidation catalyst 76 and a downstream gas temperature sensor 130 that detects the exhaust temperature of the diesel oxidation catalyst 65 on the exhaust gas discharge side are provided. The electrical wiring connector 129 of the upstream gas temperature sensor 128 and the electrical wiring connector 131 of the downstream gas temperature sensor 130 are fixed to the sensor bracket 124. Based on the detection result of the exhaust temperature inside the exhaust gas purification case 62 (outputs of the sensors 128 and 130), appropriateness or warning display is executed. Since the space between the exhaust gas purification device 61 and the sensor bracket 124 is shielded by the support frame 96, the wiring of the differential pressure sensor 122 or the connectors 129 and 131 can be simplified. Other configurations are the same as those of the first embodiment shown in FIGS.
　図１５～図１８に示す如く、ディーゼルエンジン１４の排気ガスを処理する排気ガス浄化装置６１を備え、ディーゼルエンジン１４の排気管としての排気出口管１１６に排気ガス浄化装置６１の排気ガス取入れ口としての浄化入口管８６を接続させる作業機搭載用エンジン装置において、ディーゼルエンジン１４が載置される機体フレームとしてのエンジンルームフレーム９１の上部下面側に、固定具としての吊下げ固定具３９５を介して排気ガス浄化装置６１を配置し、排気ガス浄化装置６１の下面側に浄化入口管８６を下向きに開口させている。したがって、吊下げ固定具３９５を介して、エンジンルームフレーム９１の高位置に排気ガス浄化装置６１を組付けることができる。排気ガス浄化装置６１の設置スペースを容易に確保でき、エンジンルーム９２容積または排気ガス浄化装置６１容積が制限されることがない。また、排気ガス浄化装置６１に供給される排気ガスの温度が低下しない（自己再生能力が低減しない）範囲内で、排気ガス浄化装置６１を簡単な取付け構造にて支持できる。さらに、ディーゼルエンジン１４停止時に、排気ガス浄化装置６１の放熱にてその周辺が高温になる弊害を低減できる。 As shown in FIGS. 15 to 18, an exhaust gas purification device 61 for processing exhaust gas of the diesel engine 14 is provided, and an exhaust outlet pipe 116 as an exhaust pipe of the diesel engine 14 is provided as an exhaust gas intake port of the exhaust gas purification device 61. In the engine device for mounting the working machine to which the purification inlet pipe 86 is connected, a suspension fixture 395 as a fixture is provided on the upper lower surface side of the engine room frame 91 as a machine frame on which the diesel engine 14 is placed. An exhaust gas purification device 61 is arranged, and a purification inlet pipe 86 is opened downward on the lower surface side of the exhaust gas purification device 61. Therefore, the exhaust gas purification device 61 can be assembled at a high position of the engine room frame 91 via the hanging fixture 395. The installation space for the exhaust gas purification device 61 can be easily secured, and the volume of the engine room 92 or the volume of the exhaust gas purification device 61 is not limited. Further, the exhaust gas purification device 61 can be supported with a simple mounting structure within a range where the temperature of the exhaust gas supplied to the exhaust gas purification device 61 does not decrease (the self-regeneration capability does not decrease). Further, when the diesel engine 14 is stopped, it is possible to reduce the adverse effect that the periphery of the exhaust gas purifying device 61 becomes hot due to heat radiation.
　図１５～図１８に示す如く、排気ガス浄化装置６１の上面側に吊下げ固定具３９５の一端側を連結すると共に、エンジンルームフレーム９１の上面側に吊下げ固定具３９５の他端側を延設し、エンジンルームフレーム９１の上面側に上方から吊下げ固定具３９５の他端側を当接させ、エンジンルームフレーム９１の上面側に吊下げ固定具３９５を締結している。したがって、排気ガス浄化装置６１に吊下げ固定具３９５を組付けた状態で、排気ガス浄化装置６１と吊下げ固定具３９５を一体的に昇降操作してエンジンルームフレーム９１に着脱させることができ、排気ガス浄化装置６１の組付け作業性または取外し作業性を向上できる。 As shown in FIGS. 15 to 18, one end side of the suspension fixture 395 is connected to the upper surface side of the exhaust gas purifying device 61, and the other end side of the suspension fixture 395 is extended to the upper surface side of the engine room frame 91. The other end side of the suspension fixture 395 is brought into contact with the upper surface side of the engine room frame 91 from above, and the suspension fixture 395 is fastened to the upper surface side of the engine room frame 91. Therefore, the exhaust gas purification device 61 and the hanging fixture 395 can be integrally moved up and down to be attached to and detached from the engine room frame 91 in a state where the hanging fixture 395 is assembled to the exhaust gas purification device 61. The assembly workability or removal workability of the exhaust gas purification device 61 can be improved.
　図１５～図１８に示す如く、ディーゼルエンジン１４設置部に隣接した作業部としての脱穀装置５に向けて、エンジンルームフレーム９１のうち上面フレーム９４の一部を突設させると共に、上面フレーム９４の突設部に吊下げ固定具３９５を介して排気ガス浄化装置６１を配置している。したがって、ディーゼルエンジン１４設置部と、これに隣接した脱穀装置５との間に形成されるデッドスペースを活用して、排気ガス浄化装置６１をコンパクトに支持できる。ディーゼルエンジン１４設置部と脱穀装置５にて排気ガス浄化装置６１が包囲されるように構成でき、高温になる排気ガス浄化装置６１に作業者などが接触するのを容易に防止できるものでありながら、排気ガス浄化装置６１を機外側に露呈させて、ディーゼルエンジン１４停止時などにおいて、排気ガス浄化装置６１の温度を速やかに低下させることができる。 As shown in FIGS. 15 to 18, a part of the upper frame 94 protrudes from the engine room frame 91 toward the threshing device 5 as a working unit adjacent to the diesel engine 14 installation unit. An exhaust gas purifying device 61 is disposed on the projecting portion via a hanging fixture 395. Therefore, the exhaust gas purification device 61 can be compactly supported by utilizing a dead space formed between the diesel engine 14 installation portion and the threshing device 5 adjacent thereto. The exhaust gas purifying device 61 can be configured to be surrounded by the diesel engine 14 installation portion and the threshing device 5, while it is possible to easily prevent workers from coming into contact with the exhaust gas purifying device 61 that becomes high temperature. The exhaust gas purification device 61 can be exposed to the outside of the machine, and the temperature of the exhaust gas purification device 61 can be quickly reduced when the diesel engine 14 is stopped.
　図１５～図１８に示す如く、ディーゼルエンジン１４が設置されるエンジンルーム９２側の機体上面と、ディーゼルエンジン１４設置部に隣接した脱穀装置５側の機体上面との間に、吊下げ固定具３９５を介して排気ガス浄化装置６１を配置している。したがって、脱穀装置５の上面側に向けて排気ガス浄化装置６１の一側面が開放されるように構成でき、ディーゼルエンジン１４設置部と脱穀装置５の間に排気ガス浄化装置６１の冷却風路を形成できる。ディーゼルエンジン１４を運転中、排気ガス浄化装置６１の温度を必要以上に保って、排気ガス浄化装置６１の自己再生能力を維持できるものでありながら、ディーゼルエンジン１４を停止させたときに、排気ガス浄化装置６１の温度を短時間で降下させることができる。排気ガス浄化装置６１の排熱にて周囲の構成部品が加熱される不具合の発生などを低減できる。 As shown in FIGS. 15 to 18, a suspension fixture 395 is provided between the upper surface of the body on the engine room 92 side where the diesel engine 14 is installed and the upper surface of the body on the side of the threshing device 5 adjacent to the diesel engine 14 installation portion.
