<P>PROBLEM TO BE SOLVED: To continue the cleaning process of exhaust gas of a combine harvester by regenerating a DPF (diesel particulate filter) during discharging work of unhulled rice of the combine harvester. <P>SOLUTION: The combine harvester includes: an auger (20) that discharges the unhulled rice in a grain tank (15); an unhulled rice discharge switch (26) to start the auger (20); and an exhaust gas temperature sensor (27) detecting temperature of an exhaust pipe (3) that discharges and guides the exhaust gas of an engine (1), and automatically performs DPF regeneration control (41) when the exhaust gas temperature detected by the exhaust gas temperature sensor (27) is lower than a set temperature upon turning on the unhulled rice discharge switch (26). Video from a monitoring camera (21) that takes a picture of the exhaust position of an external discharge pipe (25) is displayed on a monitor (23) disposed in front of an operation board (17). Further, when the temperature measured by a non-contact type surface thermometer (24) for measuring a field temperature at an exhaust position of the external exhaust pipe (25) reaches a temperature right before ignition, the combine harvester issues an alarm. <P>COPYRIGHT: (C)2012,JPO&INPIT |
