The second input display image 184 corresponding to the second slide switch 20R is an image showing the maximum flow rate level corresponding to the fourth operation direction of the second slide switch 20R.

In the present embodiment, the display control unit 60 includes the first input display image 181 and the second input display image 184 corresponding to the first flow rate control valve 33D (first slide switch 20L), and the second flow rate control valve 33E. To display the first input display image 181 and the second input display image 184 corresponding to the (second slide switch 20R) on the flow rate setting screen Q3, four indicators are displayed on the flow rate setting screen Q3. The number of indicators varies depending on the number of control valves 33 at which 76 sets the maximum flow level. For example, when the flow rate setting unit 76 has three control valves 33 for setting the flow rate of the hydraulic oil, the number of indicators on the flow rate setting screen Q3 is six.

As shown in FIG. 15, the first input display image 181 includes a first setting scale 182 indicating a scale of the maximum flow rate level and a first setting index 183 indicating the maximum flow rate level in association with the first setting scale 182. , Is included. The display control unit 60 causes the first setting index 183 to be expanded and contracted in the vertical direction along the first setting scale 182 according to the maximum flow rate level to be set and displayed.
As shown in FIG. 15, the second input display image 184 includes a second setting scale 185 indicating a scale of the maximum flow rate level and a second setting index 186 indicating the maximum flow rate level in association with the second setting scale 185. , Is included. The display control unit 60 displays the second input display image 184 to the left of the first input display image 181. Further, the display control unit 60 causes the second setting index 186 to be expanded and contracted in the vertical direction along the second setting scale 185 according to the maximum flow rate level to be set and displayed.

The display control unit 60 displays the unidirectional image (supply/discharge setting image) I10a indicating that the supply/discharge direction of the hydraulic oil corresponding to the selected attachment 17 is only unidirectional, or bidirectional indicating that the operation oil is bidirectional. The image 110b is displayed near (for example, below) the flow rate setting images 181, 184 corresponding to the slide switches 20L, 20R for operating the attachment 17.

For example, when the switching valve 50 is switched to the first position 50a and the hydraulic fluid is discharged from the attachment 17 to the hydraulic fluid tank T via the second flow rate control valve 33E, the display control unit 60 causes the display control unit 60 to display the flow rate setting image 181,. The interactive image 110b is displayed in the vicinity of 184. On the other hand, when the switching valve 50 is switched to the second position 50b and the hydraulic oil is discharged from the attachment 17 to the hydraulic oil tank T without passing through the second flow rate control valve 33E, the display control unit 60 indicates that the supply/discharge direction is The unidirectional image 110a is displayed below the first input display image 181 and/or the second input display image 184, which are unidirectional only. When the switching valve 50 is switched to the second position 50b and the working oil is discharged from the attachment 17 to the working oil tank T without passing through the second flow rate control valve 33E, the working oil is discharged from the attachment 17. Since the hydraulic oil supplied to the port inevitably becomes zero, the display control unit 60 automatically zeroes and displays the second input display image 184 of the second flow rate control valve 33E (right operation switch 20R). It may be allowed to. As a result, the operator can omit the operation of the display device 57, so that the work efficiency of the work machine 1 can be further improved.

In the present embodiment, the flow rate setting screen Q3 automatically sets the first supply flow rate (first input display image 181) of the second flow rate control valve 33E to zero, but the switching valve 50 is provided in a different oil passage. If not, this is not the case. For example, when the switching valve 50 is provided in the first oil passage 44 and the hydraulic oil is discharged from the attachment 17 to the hydraulic oil tank T without passing through the first flow control valve 33D, the first flow control valve 33D is operated. The first input display image 181 automatically shows zero. As a result, the switching valve 50 discharges the hydraulic oil discharged from the attachment 17 to the hydraulic oil tank T. Therefore, when it is not necessary to set the flow rate of the hydraulic oil discharged from the attachment 17, the operator performs the operation. The hydraulic oil supplied to the attachment 17 can be set to zero without performing the operation. In addition, when the operator discharges the hydraulic oil to the hydraulic oil tank T without using the flow control valve (the first flow control valve 33D or the second flow control valve 33E) by the switching valve 50, the operator discharges the hydraulic oil. It is possible to easily confirm that the flow rate on the switching side cannot be changed and the switching information of the switching valve 50. As a result, useless operation of the display operation tool 63 can be omitted and the work efficiency of the work machine 1 can be further improved.

The images 181 and 184 are displayed in an inactive state. As a result, the operator can visually recognize the acceptance of the setting of the flow rate of the hydraulic oil by the flow rate setting unit 76 and the switching information of the switching valve 50. Therefore, when it is not necessary to set the flow rate of the hydraulic oil to be supplied to the attachment 17, such as when the switching valve 50 discharges the hydraulic oil discharged from the attachment 17 to the hydraulic oil tank T, the worker can make the first supply. The waste of setting the flow rate or the second supply flow rate can be suppressed. Note that the display control unit 60, for the attachment 17 (for example, the bucket X1) in which neither of the slide switches 20L and 20R is used for operating the selected attachment 17, the flow rate setting images 181, 184 corresponding to the attachment 17. Are all displayed in the inactive state.
