Abstract:
To provide a combine that can increase safety in the circumferences of a supply device of urea water equipped in an exhaust gas purification device.SOLUTION: An exhaust air purification filter 12 for collecting particulate matters in exhaust gas exhausted from an engine and a urea purification device 14 for purifying a nitrogen oxide in the exhaust gas passing the exhaust air purification filter 12 is provided in a spacing part in a longitudinal direction of a threshing device 4 and a grain tank. A grain lifting cylinder 38 for reducing a second object being threshed from a lower part to an upper part of the threshing device 4 is provided in a downward sloped manner at a grain tank side of the threshing device 4. A supply device 18 for pumping the urea water toward the urea purification device 14 is provided in front of a dust removal opening 39 formed in the grain lifting cylinder 38 and discharging dust and dirt in a second article to the outside. When a detection device for detecting the dust and dirt being discharged from a dust removal opening 39 to the outside of the grain lifting cylinder 38 detects a discharged state of the dust and dirt, execution of regeneration treatment for warming the exhaust air purification filter 12 is prohibited.SELECTED DRAWING: Figure 7
