Abstract

A shovel includes a lower traveling body; an upper turning body that is installed on the lower traveling body; an internal-combustion engine disposed in the upper turning body; an oil hydraulic pump that discharges hydraulic oil by power of the internal-combustion engine; a hydraulic actuator that is driven by the hydraulic oil discharged by the oil hydraulic pump; a fuel container that stores fuel of the internal-combustion engine; a first detector that detects a residual quantity state of the fuel; a reducing agent container that stores a reducing agent to be used in a selective catalytic reduction system; a second detector that detects a residual quantity state of the reducing agent; and an image display unit that is installed in a cabin, wherein the image display unit is configured to simultaneously image-display the residual quantity state of the fuel and the residual quantity state of the reducing agent.

Claims

1. A shovel that performs works upon being operated by a driver, the shovel comprising:

a lower traveling body;

an upper turning body that is installed on the lower traveling body;

an internal-combustion engine that is disposed in the upper turning body;

an oil hydraulic pump that discharges hydraulic oil by power of the internal-combustion engine;

a hydraulic actuator that is driven by the hydraulic oil that is discharged by the oil hydraulic pump;

a fuel container that stores fuel of the internal-combustion engine;

a reducing agent container that stores a reducing agent that is to be used in a selective catalytic reduction system;

a display device that is installed in a cabin of the shovel;

a processor; and

a memory,

wherein the processor detects a residual quantity state of the fuel in the fuel container,

wherein the processor detects a residual quantity state of the reducing agent in the reducing agent container,

wherein the processor causes, while the shovel is operated, the display device to simultaneously image-display an image that is captured by a rear monitoring camera, a setting state of the shovel set by the driver, the setting state including a revolution speed mode of the internal-combustion engine, the residual quantity state of the fuel, the residual quantity state of the fuel indicating one of driving conditions of the shovel, and the residual quantity state of the reducing agent, the residual quantity state of the reducing agent indicating another one of the driving conditions of the shovel, and wherein, based on the detected residual quantity state of the reducing agent, the processor causes the display device to image-display the residual quantity state of the reducing agent such that a normal range display is included in an image of the residual quantity state of the reducing agent, so that a deviation from a normal range of a residual quantity of the reducing agent can be visually recognized.

2. The shovel according to claim 1, wherein the processor causes the display device to image-display the residual quantity state of the fuel and the residual quantity state of the reducing agent at a side that is close to a driver'"'"'s seat in a display area, and

wherein the processor causes the display device to image display the image that is captured by the rear monitoring camera at a side that is distant from the driver'"'"'s seat in the display area.

3. The shovel according to claim 1, wherein the processor detects a temperature of a coolant of a cooling circuit in the internal-combustion engine,

wherein the processor causes the display device to image-display a temperature state of the coolant, together with the residual quantity state of the fuel and the residual quantity state of the reducing agent.

4. The shovel according to claim 1, wherein the processor detects a temperature of a hydraulic oil for driving an attachment,

wherein the processor causes the display device to simultaneously image-display a temperature state of the hydraulic oil, and the residual quantity state of the fuel and the residual quantity state of the reducing agent.

5. The shovel according to claim 1, wherein the processor causes the display device to simultaneously image-display accumulated operation time of the shovel, and the residual quantity state of the fuel and the residual quantity state of the reducing agent.

6. The shovel according to claim 1, wherein the processor causes the display device to image-display the residual quantity state of the fuel and the residual quantity state of the reducing agent by bar graphs.

7. The shovel according to claim 6, wherein the bar graphs form parts of a predetermined circle.

8. The shovel according to claim 1,

wherein processor causes the display device to image-display the residual quantity state of the fuel and the residual quantity state of the reducing agent at an upper side in a display area, and

wherein the processor causes the display to image-display the image that is captured by the rear monitoring camera at a lower side in the display area.

9. The shovel according to claim 1, wherein the processor causes the display device to image-display a clogging condition of a diesel particulate filter.

10. The shovel according to claim 1, further comprising:

a controller that determines abnormality based on the residual quantity state of the reducing agent detected by the processor,

wherein the controller automatically changes a control state of the internal-combustion engine.

11. The shovel according to claim 1, wherein, in response to detecting that the image captured by the rear monitoring camera is superposed with the image of the residual quantity state of the reducing agent, the processor causes the display device to to display the image of the residual quantity state of the reducing agent in front of the image captured by the rear monitoring camera.

12. The shovel according to claim 1, further comprising:

a controller that receives data representing the residual quantity state of the reducing agent detected by the processor; and

an engine control unit that automatically changes a control state of the internal-combustion engine.

13. The shovel according to claim 12, wherein the engine control unit receives data representing the residual quantity state of the fuel detected by the processor.
