Definitions
- the present invention relates to a work machine provided with an exhaust gas treatment device.
- an exhaust gas treatment device that purifies an exhaust gas by collecting particulate matter in the exhaust gas discharged from an engine with a filter.
- the flow resistance of the filter increases, the collection capacity of the particulate matter decreases, and the output of the engine decreases. Therefore, when the above-mentioned accumulated amount exceeds the set amount, the particulate matter accumulated on the filter is burnt off and removed by changing the operating conditions of the engine to raise the temperature of the exhaust gas, and the particulate matter on the filter is removed.
- Filter regeneration is performed to restore the collection ability of the particles.
- the amount of particulate matter deposited on the filter and the progress of filter regeneration are displayed, for example, on the display unit of the vehicle (see, for example, Patent Document 1). As a result, the operator can recognize the progress of the filter reproduction by looking at the display unit.
- the present invention has been made to solve the above-mentioned problems, and an object thereof is to make an operator aware of the progress of filter regeneration at the time of filter regeneration of an exhaust gas treatment device, and at the same time, to ensure the safety of the surroundings.
- the purpose is to provide a work machine that can be encouraged.
- the working machine includes an engine, an exhaust gas treatment device having a filter for collecting particulate matter in the exhaust gas discharged from the engine, and the filter by raising the temperature of the exhaust gas.

- the bucket 33 is rotatably attached to the tip of the arm 32 via a pin 34. Further, the bucket 33 is connected to the bucket cylinder 33a via the link mechanism 35.
- a hook 36 is attached to the tip of the arm 32.
- the hook 36 is a hook-shaped member for performing crane work, and is rotatably provided on the link mechanism 35.
- the crane work refers to a hanging work of suspending and raising / lowering an object to be suspended.
- the hook 36 is rotatably supported with the axis of the link mechanism 35 as a rotation fulcrum, and is in a deployed state (see FIG. 1) protruding from the bucket 33 and a stored state stored in the bucket 33 side (not shown). ) And the posture can be changed. For example, when excavating with the bucket 33, the hook 36 is stored. On the other hand, when the crane work is performed by the hook 36, the hook 36 is put into the deployed state.
- the upper swivel body 4 is configured to be swivelable with respect to the lower traveling body 2 via a swivel bearing (not shown).
- a control unit 41, a swivel table 42, a swivel motor 43, an engine room 44, and the like are arranged in the upper swivel body 4.
- the upper swivel body 4 is swiveled via a swivel bearing by being driven by a swivel motor 43 which is a hydraulic motor.
- a plurality of hydraulic pumps are arranged in addition to the engine 40 that provides power to each part.
- Each hydraulic pump supplies hydraulic oil (pressure oil) to a hydraulic motor (for example, left and right traveling motors 22 and swivel motor 43) and a hydraulic cylinder (for example, blade cylinder 23a, boom cylinder 31a, arm cylinder 32a, bucket cylinder 33a).
- a hydraulic motor and a hydraulic cylinder that are driven by supplying hydraulic oil from an arbitrary hydraulic pump are collectively called a hydraulic actuator.
- a driver's seat 41a is arranged in the control unit 41 on which the operator rides.
- An operation unit 41b is arranged around the driver's seat 41a (particularly forward, left and right).
- the operation unit 41b is composed of an operation lever, a switch, a button, etc. for driving the hydraulic actuator.
- the hydraulic actuator is driven by the operator sitting on the driver's seat 41a and operating the operation unit 41b.
- the lower traveling body 2 can travel, the ground leveling work by the blade 23, the excavation work by the working machine 3, the crane work, the turning of the upper turning body 4, and the like can be performed.
- the operation unit 41b includes a cutoff lever.
- the cutoff lever is provided so as to be rotatable up and down in the vicinity of the driver's seat 41a.
- the cutoff switch (not shown) is turned on, and the operation unit 41b is operated to drive a predetermined hydraulic actuator (effective state).
- the cutoff switch is turned off, and even if the operator operates the operation unit 41b, the hydraulic actuator cannot be driven (invalid state).
- the operator tries to get off the control unit 41, the operator pulls up the cutoff lever to make the hydraulic actuator inoperable, and then leaves the control seat 41a.
- FIG. 2 is an explanatory diagram schematically showing the configuration of the exhaust system of the hydraulic excavator 1.
- the engine 40 described above is, for example, a diesel engine and has an intake pipe 51.
- the intake pipe 51 sucks gas from the outside and supplies it to the intake manifold 52.
- the intake manifold 52 divides the gas supplied from the intake pipe 51 into a number according to the number of cylinders (cylinders) (for example, four in FIG. 2) and supplies the gas to the cylinder head 53.
- the cylinder head 53 is provided with a plurality of cylinders and injectors.
- the injector is a fuel injection device that injects fuel into the combustion chamber of each cylinder at a predetermined timing.
- the injection of fuel by the injector is controlled by the engine control unit 50, which is also called an engine control unit (ECU).
- ECU engine control unit
- the EGR device 60 is an exhaust gas recirculation device that returns a part of the gas to the intake pipe 51, and includes an EGR pipe 61, an EGR cooler 62, and an EGR valve 63.

As a result, the amount of oxygen in the intake gas is reduced, so that the combustion temperature can be lowered. As a result, it is possible to reduce the generation of nitrogen oxides called NOx, and it is possible to comply with emission regulations (emission regulations).
- the rest of the gas discharged from the cylinder head 53 via the exhaust manifold 54 is sent to the exhaust gas treatment device 70 via the exhaust pipe 55.
