The shutter can be disposed alternatively at a first position at which the shutter protrudes forward from a lower end of a blade or at a second position at which the shutter is farther away from the lower end than at the first position. The controller is configured to receive an input of an operation instruction from an input operation unit for moving the shutter from the second position to the first position, to cause the shutter to move from the second position to the first position. After a lapse of a prescribed time period since the shutter is moved to the first position, the controller causes the shutter to move from the first position to the second position.

Abstract: An exhaust gas purification material according to the present invention is provided with a particulate filter 10 that traps particulate matter in exhaust gas and contains an SCR catalyst for adsorbing ammonia and reducing NOx in the exhaust gas. A maximum allowable adsorption amount of ammonia adsorbable by the filter 10 differs between an upstream portion 10a of the filter 10 including an exhaust gas inlet-side end 10c, and a downstream portion 10b of the filter 10 including an exhaust gas outlet-side end 10d. The SCR catalyst contained in the upstream portion 10a and the SCR catalyst contained in the downstream portion 10b are qualitatively different. A ratio (B/A) of a maximum allowable adsorption amount of ammonia A in the upstream portion 10a and a maximum allowable adsorption amount of ammonia B in the downstream portion 10b satisfies the relationship 1.1?(B/A)?2.
