Abstract

A work vehicle allows an operator to easily check the vertical position and the angle of bucket. The work vehicle includes a front loader with a bucket, and freely raises/lowers and rotates the bucket. The work vehicle comprises a display disposed near an operator seat. The display is configured to display vertical position information and angle information of the bucket.

First claim

The invention claimed is:

1. A work vehicle including a work machine with a bucket, which is configured to freely raise/lower and rotate the bucket, the work vehicle comprising:
a display disposed near an operator seat,
wherein:
the display is configured to:
concurrently display vertical position information and angle information, wherein the vertical position information is synchronized with an upward/downward movement of the bucket, and wherein the angle information of the bucket is synchronized with a rotational movement of the bucket, and
display a screen for enabling or not enabling an automatic standby function of automatically setting the bucket at a set angle and a set vertical position respectively.

2. The work vehicle according to claim 1 , wherein the display is further configured to display:
vertical position setting information as an index of the upward/downward movement of the bucket, and to display
angle setting information as an index of the rotational movement of the bucket.

3. The work vehicle according to claim 2 , wherein:
the display includes an operation section that allows operation for setting the vertical position setting information and the angle setting information.

4. The work vehicle according to claim 1 , further comprising:
a control section,
wherein:
the display includes a display section configured to display in a selectable manner,
a plurality of work machines that are attached to and linkable to the work vehicle, and to display
in an identifiable manner one of the work machines that is linked to the work vehicle; and

an operation section that allows operation for linking the work vehicle to one of the work machines displayed on the display section, and

the control section cuts a linkage between the work vehicle and one of the work machines that is linked thereto and makes a linkage between the work vehicle and desired one of the work machines when the operation section is operated to link the work vehicle to the desired one of the work machines.

5. The work vehicle according to claim 1 , wherein:
the vertical position information comprises a first vertical indicator configured to move upward or downward on the display in synchronization with an upward/downward movement of the bucket; and
the angle information comprises a first rotational indicator configured to move left or right on the display in synchronization with a rotational movement of the bucket.

6. The work vehicle according to claim 5 , wherein the display is further configured to display:
vertical position setting information that comprises a second vertical indicator as a vertical index of the upward/downward movement of the bucket; and
angle setting information that comprises a second rotational indicator as rotational index of the rotational movement of the bucket.

7. The work vehicle according to claim 6 , wherein:
the vertical index comprises a predetermined range based on the second vertical indicator; and
based on the first vertical indicator moving outside the predetermined range, the display is configured to output a notification.

8. The work vehicle according to claim 6 , wherein:
the display includes an operation section that is selectable and allows operation for setting the vertical index and the rotational index.

9. The work vehicle according to claim 8 , wherein:
the first vertical indicator is configured to move upward on the display based on a vertical position of the bucket being raised, and move downward on the display based on the vertical position of the bucket being lowered; and
the first rotational indicator is configured to move rightward on the display based on an increase in a rotation angle of the bucket, and move leftward on the display based on a decrease in the rotation angle of the bucket.

10. The work vehicle according to claim 9 , wherein, based on selection of the operation section, the display is configured to:
set the second vertical indicator to correspond to a vertical position of the bucket; and
set the second rotational indicator to correspond to a rotation angle of the bucket;
wherein:
the second vertical indicator is configured to not move with the upward/downward movement of the bucket; and
the second rotational indicator is configured to not move with the rotational movement of the bucket.

11. The work vehicle according to claim 1 , further comprising:
a control device,
wherein:
the display is further configured to display:
a work machine linkage view that presents:
in a selectable manner, a plurality of work machines that are attached to and linkable to the work vehicle; and
in an identifiable manner, one of the plurality of work machines that is linked to the work vehicle; and

an automatic standby setting view that allows operation for linking the work vehicle to one of the work machines presented via the work machine linkage view, and

the control device is configured to, based on a selection to link the work vehicle to a particular one of the work machines of the plurality of work machines:
remove a linkage between the work vehicle and one of the work machines that is linked thereto; and
establish a linkage between the work vehicle and the particular one of the work machines.

12. The work vehicle according to claim 1 , wherein the screen for enabling or not enabling the automatic standby function of automatically setting the bucket at the set angle and the set vertical position comprises a standby view.

13. The work vehicle according to claim 1 , wherein the display includes one or more icons configured to be selected by an operator.

14. The work vehicle according to claim 13 , wherein the one or more icons include:
a first icon is configured to display an automatic standby setting screen when selected by an operator in which an automatic standby function can be enabled or disabled;
a second icon is configured to display a work machine linkage screen in which a plurality of work machines that are attached to the work vehicle are displayed such that an operator can select one of the plurality of work machines to be linked to the display; and
a third icon configured to enable or disable a floating function.
