EXHAUST GAS PURIFICATION CONTROL DEVICE FOR CONSTRUCTION MACHINE

摘要

An exhaust gas purification control device is provided with: an engine; an actuator using the engine as a drive source: a manipulation unit for a manipulator to manipulate the actuator or the engine; a manipulation detection unit for detecting the presence or absence of the manipulation of the manipulation unit; a purification device for capturing soot in an exhaust gas from the engine; a deposition amount detection unit for detecting the deposition amount of the soot captured by the purification device; a regeneration unit for performing a regeneration operation (an operation for regenerating the purification device by burning the soot captured by the purification device); and a control unit for controlling the regeneration operation. The control unit performs switching from control for placing priority on the manipulation of the manipulation unit to control for placing priority on the regeneration operation in stages as the deposition amount of the soot detected by the deposition amount detection unit increases.
