Disclosed is an arrangement structure of an exhaust gas after-treatment device for a combine. According to an embodiment of the present invention, the arrangement structure of an exhaust gas after-treatment device for a combine, with respect to a structure for arranging and mounting an exhaust gas after-treatment device for purifying engine exhaust gas of a combine in an engine (10) and a main frame (20), comprises: a PM reduction device having exhaust gas discharged from the engine (10) introduced thereinto, and disposed adjacent to an upper portion of the engine (10) to be fixated on a vehicle body frame around the engine (10); and a NOx reduction device (120) connected to the PM reduction device (110) through a connection pipe (30) to introduce the exhaust gas passing through the PM reduction device (110), and disposed on an upper portion of the main frame (20) in the forward and rearward direction to be fixated on the main frame (20) by using a fixing member (130). According to the present invention, even in the case of a structure such as a combine where the upper and lower widths of an engine room are narrow to mount an exhaust gas after-treatment device on an upper portion of an engine, it is possible to effectively mount and use the exhaust gas after-treatment device without a separate layout change, to improve space utilization inside the engine room of the combine, to place and fixate the after-treatment device with a compact structure without reducing the volume of a grain tank, and to stably maintain the performance of the exhaust gas after-treatment device by buffering and absorbing vibration transmitted from the engine.

    콤바인의 배기가스 후처리장치 배치구조가 게시된다. 본 발명의 실시예에 따른 콤바인의 배기가스 후처리장치 배치구조는: 콤바인의 엔진 배기가스를 정화시키기 위한 배기가스 후처리장치를 엔진(10)과 주프레임(20)에 배치하여 장착하는 구조에 있어서, 엔진(10)으로부터 배출되는 배기가스가 인입되고, 엔진(10)의 상부에 인접하여 배치되어 엔진(10) 주변의 차체프레임상에 고정되는 PM저감장치(110); 및 PM저감장치(110)와 연결파이프(30)를 통해 상호 연결되어 PM저감장치(110)를 통과한 배기가스가 인입되고, 주프레임(20)의 상부에 콤바인의 전후방향으로 배치되어 주프레임(20) 상에 고정부재(130)를 이용하여 고정되는 NOx저감장치(120);를 포함하는 것을 구성의 요지로 한다. 본 발명에 따르면, 콤바인(combine)과 같이 엔진룸의 상하폭이 협소하여 엔진 상부에 배기가스 후처리장치를 장착하기 힘든 구조의 경우에도 별도의 레이아웃(lay-out) 변경 없이 배기가스 후처리장치를 효과적으로 장착하여 사용할 수 있고, 콤바인 엔진룸 내부의 공감 활용성을 향상시킬 수 있고, 이와 동시에 곡물탱크의 용량을 축소하지 않고 콤팩트한 구조로 후처리장치를 배치하여 고정할 수 있으며, 엔진으로부터 전달되는 진동을 완충 및 흡수시켜 배기가스 후처리장치의 성능을 안정적으로 유지할 수 있다.
