摘要： An exhaust purifying device (10) includes a throttle valve (20), a DOC device (30), an SCR device (50), a fuel injector (7), an inlet temperature sensor (31), an outlet temperature sensor (45), and a controller (8). The controller (8) includes a heatup-control execution control unit (82) configured to perform a regeneration treatment for removing a urea deposit when a predetermined heatup control execution condition is met, and a condition judgment unit (83) configured to judge whether or not the first condition is met during the regeneration treatment by the heatup control.
