Abstract

A shovel includes a cabin, a display device attached to the cabin, and a main pump. An internal combustion is configured to drive the main pump. An information acquiring device is provided. A controller is configured to calculate an amount of work based on the information acquired by the information acquiring device and to cause the display device to display the amount of work per predetermined period of time in a chronological order.

First claim

What is claimed is:

1. A shovel, comprising:
a lower traveling body;
an upper turning body rotatably mounted on the lower traveling body;
a cabin provided on the upper turning body;
an attachment attached to the upper turning body, the attachment including a boom, an arm, and an end attachment;
a display device attached to the cabin;
a main pump provided on the upper turning body;
a power source provided on the upper turning body and configured to drive the main pump;
an information acquiring device configured to acquire information; and
a hardware processor configured to calculate an amount of work per predetermined period of time based on the information acquired by the information acquiring device and to cause the display device to display the amount of work calculated per the predetermined period of time in a chronological order, the amount of work being a cumulative value of volumes, a cumulative value of weights, or a combination thereof of a material excavated with the attachment, the volumes being calculated one for each of a plurality of excavations performed within the predetermined period, the weights being calculated one for each of the plurality of excavations performed within the predetermined period.

2. The shovel as claimed in claim 1 , wherein the hardware processor is configured to calculate a work amount fuel economy based on the information acquired by the information acquiring device, and to cause the display device to display the work amount fuel economy per the predetermined period of time in the chronological order, the work amount fuel economy being a fuel consumption per unit amount of work or an amount of work per unit fuel consumption.

3. The shovel as claimed in claim 1 , wherein the hardware processor is configured to calculate each of the volumes of the excavated material per the predetermined period of time based on a change in landform derived from an image taken by an imaging device.

4. The shovel as claimed in claim 1 , wherein
the end attachment is a bucket, and
the hardware processor is configured to calculate each of the volumes of the excavated material in the bucket based on an image of the bucket taken by an imaging device.

5. The shovel as claimed in claim 1 , wherein the hardware processor is configured to calculate each of the volumes of the excavated material based on a change in attitude of the attachment derived from the information acquired by the information acquiring device.

6. The shovel as claimed in claim 1 , wherein
the end attachment is a bucket, and
the hardware processor is configured to calculate each of the weights of the excavated material in the bucket based on a pressure of a hydraulic oil in a hydraulic cylinder configured to drive the attachment.

7. The shovel as claimed in claim 1 , wherein the hardware processor is configured to cause the display device to display a number of dump trucks relating to the amount of work.

8. The shovel as claimed in claim 1 , wherein
the amount of work is the cumulative value of the volumes and the cumulative value of the weights, and
the hardware processor is configured to cause the display device to simultaneously display the cumulative value of the volumes and the cumulative value of the weights.

9. The shovel as claimed in claim 1 , wherein the hardware processor is configured to cause the display device to simultaneously display a first work amount fuel economy based on the calculated weights of the excavated material per the predetermined period of time and a second work amount fuel economy based on the calculated volumes of the excavated material per the predetermined period of time.

10. The shovel as claimed in claim 1 , wherein the hardware processor is configured to cause the display device to display information about a type of the excavated material.

11. A support device used for a shovel, the shovel including a lower traveling body, an upper turning body rotatably mounted on the lower traveling body, an attachment attached to the upper turning body, the attachment including a boom, an arm, and an end attachment, a main pump provided on the upper turning body, a power source provided on the upper turning body and configured to drive the main pump, an information acquiring device configured to acquire information, and a hardware processor configured to calculate an amount of work per predetermined period of time based on the information acquired by the information acquiring device, the support device comprising:
a display device; and
a hardware processor configured to receive the amount of work calculated per the predetermined period of time from the shovel and cause the display device to display the amount of work calculated per the predetermined period of time in a chronological order, the amount of work being a cumulative value of volumes, a cumulative value of weights, or a combination thereof of a material excavated with the attachment, the volumes being calculated one for each of a plurality of excavations performed within the predetermined period, the weights being calculated one for each of the plurality of excavations performed within the predetermined period.

12. The support device as claimed in claim 11 , wherein the hardware processor of the support device is configured to cause the display device to display a work amount fuel economy per the predetermined period of time in the chronological order, the work amount fuel economy being a fuel consumption per unit amount of work or an amount of work per unit fuel consumption calculated based on the information acquired by the information acquiring device.

13. The support device as claimed in claim 11 , wherein the hardware processor of the support device is configured to cause the display device to display a number of dump trucks relating to the amount of work.

14. The support device as claimed in claim 11 , wherein the hardware processor of the support device is configured to cause the display device to display information about a type of the excavated material.

15. A management device used for a shovel, the shovel including a lower traveling body, an upper turning body rotatably mounted on the lower traveling body, an attachment attached to the upper turning body, the attachment including a boom, an arm, and an end attachment, a main pump provided on the upper turning body, a power source provided on the upper turning body and configured to drive the main pump, an information acquiring device configured to acquire information, and a hardware processor configured to calculate an amount of work per predetermined period of time based on the information acquired by the information acquiring device, the management device comprising:
a display device; and
a hardware processor configured to receive the amount of work calculated per the predetermined period of time from the shovel and cause the display device to display the amount of work calculated per the predetermined period of time in a chronological order, the amount of work being a cumulative value of volumes, a cumulative value of weights, or a combination thereof of a material excavated with the attachment, the volumes being calculated one for each of a plurality of excavations performed within the predetermined period, the weights being calculated one for each of the plurality of excavations performed within the predetermined period.

16. The management device as claimed in claim 15 , wherein the hardware processor of the management device is configured to cause the display device to display a work amount fuel economy per the predetermined period of time in the chronol
