Problems solved by technology

[0004] However, in the construction machine described in Patent Document 1, the average fuel consumption rate of each of the past few days is displayed, but the average fuel consumption rate per hour of each day is not displayed.
Therefore, although the fuel consumption rate information can be compared on a daily basis, the fuel consumption rate information cannot be grasped and compared on an hourly basis.
Therefore, the average fuel consumption rate on a day when a work with a large amount of fuel consumption is performed in a short period of time and a day when a work with a small amount of fuel consumption is performed for a long time are displayed at the same level, and it is impossible to specifically grasp which. Reduced fuel consumption during operations may make it difficult to implement measures to improve fuel consumption

Embodiment Construction

[0017] Hereinafter, modes for implementing the invention will be described with reference to the drawings. In each drawing, the same reference numerals are assigned to the same components, and overlapping descriptions may be omitted.

[0018] figure 1 It is a side view of the excavator 100 of embodiment. On the undercarriage 1 of the excavator 100 that performs a traveling operation, a revolving upper body 3 is rotatably mounted via a revolving mechanism 2 . A boom 4 is attached to the upper revolving body 3 . Furthermore, an arm 5 is attached to the tip of the boom 4 , and a bucket 6 is attached to the tip of the arm 5 . Boom 4 , arm 5 , and bucket 6 constitute attachments, and are hydraulically driven by boom cylinder 7 , arm cylinder 8 , and bucket cylinder 9 . A driver's cabin (cockpit) 10 is provided on the upper revolving structure 3 , and a power source such as an engine as an internal combustion engine is mounted thereon. A driver's seat is provided in the driver'...

Abstract

The present invention provides a construction machine, which displays the information of the fuel consumption rate of the past few days in the past few days, and the fuel consumption rate per hour. The construction machine has: a lower body walking body to walk, an upper body rotation body freely mounted on the lower body, a cab, equipped with the upper rotary body and a fuel consumption rate calculation device, based on the running time and fuel consumption to calculate the fuel consumption rate, and the fuel consumption rate calculated by the above average fuel consumption rate of the past few days, and the average daily fuel consumption per hour from the past few days.

Description

technical field [0001] The invention relates to a construction machine. Background technique [0002] Energy saving for the purpose of environmental protection has been promoted in various industrial fields. For example, in the field of construction machines, fuel consumption is emphasized for energy saving, and a construction machine in which fuel consumption information is displayed on a display device mounted on a driver's seat has been proposed (for example, refer to Patent Document 1). According to such a construction machine, the operator is made aware of the fuel consumption rate, and the operator is urged to suppress the fuel consumption during the work as much as possible, whereby energy saving can be realized. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2013-76318 [0004] However, in the construction machine described in Patent Document 1, the average fuel consumption rate for each of the past several days is displayed, but the hourly average fuel ...
