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.

First claim

What is claimed is:

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 first detector that detects a residual quantity state of the fuel in the fuel container; a reducing agent container that stores a reducing agent that is to be used in a selective catalytic reduction system; a second detector that detects a residual quantity state of the reducing agent in the reducing agent container; 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.

2 . The shovel according to claim 1 ,
wherein the image display unit is configured to image-display an image that is captured by a rear monitoring camera, while the shovel is operated.

3 . The shovel according to claim 1 ,
wherein the image display unit is configured 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 of the image display unit, and wherein the image display unit is configured to image display an image that is captured by a rear monitoring camera at a side that is distant from the driver's seat in the display area.

4 . The shovel according to claim 1 , further comprising:
a third detector that detects a temperature of a coolant of a cooling circuit in the internal-combustion engine, wherein the image display unit is configured 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.

5 . The shovel according to claim 1 , further comprising:
a fourth detector that detects a temperature of a hydraulic oil for driving an attachment, wherein the image display unit is configured 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.

6 . The shovel according to claim 1 ,
wherein the image display unit is configured 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.

7 . The shovel according to claim 1 ,
wherein the image display unit is configured to image-display the residual quantity state of the fuel and the residual quantity state of the reducing agent by bar graphs.

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

9 . The shovel according to claim 1 ,
wherein the image display unit is configured 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 of the image display unit, and wherein the image display unit is configured to image-display an image that is captured by a rear monitoring camera at a lower side in the display area.
