Embodiment Construction
[0095] Hereinafter, modes for implementing the present invention will be described with reference to the drawings.
[0096] the whole frame
[0097] first, figure 1 with figure 2 The overall configuration of a hydraulic excavator 1 as an example of a work machine is shown. This hydraulic excavator 1 has a vehicle body 2 and a working machine 3 . The vehicle body 2 has a lower running body 4 and an upper revolving body 5 . The undercarriage 4 has a pair of traveling devices 4a. Each traveling device 4a has crawler belts 4b. Each traveling device 4 a drives the crawler belt 4 b by the right hydraulic traveling motor and the left hydraulic traveling motor (hydraulic traveling motor 21 ), so that the hydraulic excavator 1 travels or turns.
[0098] The upper revolving body 5 is rotatably provided on the lower running body 4 , and is driven by a revolving hydraulic motor 22 to turn. In addition, a cab 6 is provided on the upper revolving structure 5 . The upper revolving b...

The present invention provides a work machine capable of simply and accurately measuring the number of times of a series of digging and loading mechanism parts such as digging and loading operations, which includes: A time-integrated value obtained by time-integrating the correspondingly output physical quantity; a determination unit (31c) that preliminarily compares the above-mentioned time-integrated value with a predetermined operation of the excavation and loading mechanism unit due to the operation of the operation lever (41, 42) corresponding to the angle, and when the above-mentioned time integral value is greater than or equal to a predetermined integral value, it is determined that the operation lever (41, 42) has been operated; When the various operations of the excavation and loading mechanism unit are performed in a prescribed order, the number of operations of the series of excavation and loading operations is counted by counting a series of operations of the excavation and loading mechanism unit performed in the prescribed order as one time, When a specific state such as stagnation or skipping occurs in the sequence of operations of the above-mentioned series of digging and loading mechanism parts, the counting part (31d) corrects the counting process of the number of times of the above-mentioned series of digging and loading operations according to the specific state. .
Description
technical field [0001] The present invention relates to a working machine and a working amount measuring method of the working machine that can easily and accurately measure the number of operations of a series of digging and loading mechanism parts performed during digging and loading operations. Background technique [0002] Since manual calculation of the workload of working machines such as hydraulic excavators is a burden on operators and is cumbersome, proposals have been made to automate it. [0003] For example, Patent Document 1 describes a method of detecting a boom angle, an arm angle, and a bucket angle, and counting the number of loading times of a hydraulic excavator using the detection results. In addition, Patent Document 1 also describes monitoring and displaying the counted number of loading times. [0004] Patent Document 1: Japanese Patent Application Laid-Open No. 9-177140 Contents of the invention [0005] However, for hydraulic excavators with diff...
