Embodiment Construction

[0100] Hereinafter, modes for implementing the present invention will be described with reference to the drawings.

[0101] the whole frame

[0102] first, figure 1 and figure 2 The overall configuration of a hydraulic excavator 1 as an example of a work machine is shown. This hydraulic excavator 1 includes 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.

[0103] 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 revolvi...

Abstract

A work machine having as the purpose therefor the capability to readily and with high precision measure the number of times that a sequence of digging and loading mechanism operations, such as loading work, occurs, and manage work on the basis of the measurement results. The work machine: calculates a time-integrated value that time-integrates a physical amount output in accordance with the operation of an operation lever; associates the time-integrated value and a prescribed operation angle of the digging and loading mechanism that is consequent upon the operation of the operation lever; determines, if the time-integrated value is at least a prescribed integrated value, that the operation lever has been operated; and, if each determined operation of the digging and loading mechanism has occurred in a prescribed order, cumulatively adds, counting the number of loadings as one time. The work machine comprises: a predetermined value setting unit (62) that sets the bucket capacity; a job amount calculation unit (63) that calculates a job amount, said job amount being the number of loadings multiplied by the bucket capacity; and an I / O unit (66) that displays and outputs at least a job rate.

Description

technical field [0001] The present invention relates to a work machine and a work management system capable of easily and accurately measuring the number of operations of a series of digging and loading mechanism parts performed during excavating and loading operations, and performing work management based on the calculated results. 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] On the other hand, it is preferable to use the workload calculated manually or automatically for management. Therefore, in Patent Document 1, for example, an operator operates a count switch to count the number of times of loading, and displays the calculated cumulative number of times of loading for one day on the display screen of the hydraulic excavator.
