PROBLEM TO BE SOLVED: To provide a DPF installation structure for combine harvester that allows efficient heating of outside air and efficient cooling of an exhaust pipe of a DPF by outside air with the use of an inlet cover for covering of an inlet port and a middle part of the exhaust pipe.SOLUTION: In a DPF installation structure for combine harvester in which exhaust gas is discharged from a DPF 26 via an exhaust pipe 27, in order to discharge exhaust gas at the back of a traveling machine base 4 by passing the exhaust pipe 27 through a space between a threshing part 6 and a grain tank, a middle part of the exhaust pipe 27 is disposed to face an inlet port 31 of a blower fan 30 that is arranged by opening a front lower area of a side wall 6b of the threshing part 6 and blows screening air into the threshing part 6 by sucking air from an engine 11, and the inlet port 31 and the middle part of the exhaust pipe 27 are covered from sides by inlet covers 27a, 27b and 28c in a space against the threshing part 6 while forming an inlet path 31a that is opened in a front part and a lower part and communicates with the inlet port 31.COPYRIGHT: (C)2014,JPO&INPIT【課題】吸気口とDPFの排気パイプの中途部を吸気カバーによって覆うことにより、外気を効率よく加温しながら排気パイプを外気によって効率よく冷却することができるコンバインのDPF設置構造を提供する。【解決手段】DPF26から排気パイプ27を介し排気ガスを排出するコンバインのDPF設置構造であって、排気パイプ27を脱穀部6とグレンタンクとの間の空間部を通し走行機台4の後部に排気ガスを排出させるに、脱穀部6の側壁6bの前側下部に開口されてエンジン11側から吸気し脱穀部6内に選別風を送風する送風ファン30の吸気口31に対し排気パイプ27の中途部を臨ませると共に、吸気口31と排気パイプ27の中途部とを、吸気カバー28a,28b,28cによって脱穀部6との間で、前部と下部に開放されて吸気口31に通ずる吸気路31aを形成して側方から覆う構成にした。【選択図】図4
