PROBLEM TO BE SOLVED: To provide a combine capable of purifying nitric oxide in exhaust gas discharged from a DPF unit with a urea selective catalyst reduction device.SOLUTION: A urea selective catalyst reduction device 70 is arranged on an upper side of a DPF unit 40 capturing and purifying a particle in exhaust gas of an engine 9, the urea selective catalyst reduction device purifying nitric oxide in exhaust gas after passage through the DPF unit 40. A cover is arranged which covers right/left one side of the urea selective catalyst reduction device 70 and DPF unit 40 and opening right/left the other side. An exhaust gas inflow port of the DPF unit 40 is connected to an exhaust manifold 30B of the engine 9 through a connection pipe. An exhaust gas outflow port of the DPF unit 40 is connected to an exhaust gas inflow port of the urea selective catalyst reduction device 70 through a connection pipe 73. A tail pipe 61 is connected to an exhaust gas outflow port of the urea selective catalyst reduction device 70.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2018,JPO&INPIT【課題】尿素選択触媒還元装置によって、DPFユニットから排出される排気ガス中の窒素酸化物を浄化できるコンバインを提供する。【解決手段】エンジン9の排気ガス中の微粒子を捕集して浄化するDPFユニット40の上側に、DPFユニット40通過後の排気ガス中の窒素酸化物を浄化する尿素選択触媒還元装置70を配置し、尿素選択触媒還元装置70とDPFユニット40の左右一側を覆い左右他側を開放するカバーを設け、DPFユニット40の排気ガス流入口を接続管を介してエンジン9の排気マニホールド30Bに接続し、DPFユニット40の排気ガス流出口を連結管73を介して尿素選択触媒還元装置70の排気ガス流入口に接続し、尿素選択触媒還元装置70の排気ガス流出口にテールパイプ61を接続する。【選択図】図9
