Abstract
A shovel includes: an arm rotatably attached to a boom rotatably attached to a revolving body; a bucket rotatably attached to the arm; a tilt mechanism configured to support the bucket that can be tilted to the arm; a bucket tilt angle sensor configured to detect a tilt angle of the bucket; and a tilt angle controller configured to control adjusting the tilt angle. The tilt angle controller adjusts the tilt angle by automatic control of the tilt mechanism so that a bucket line of the bucket becomes parallel to a target excavation surface. The automatic control of the tilt mechanism is enabled after moving the shovel and/or during rotating the shovel.
Claims19
A vehicle shovel, comprising:
- an arm rotatably attached to a boom rotatably attached to a revolving body, said arm being rotatable relative to the boom on a plane perpendicular to a horizontal plane;
- a bucket rotatably attached to the arm;
- a tilt mechanism including a tilt axis that extends on the plane and is configured to rotatably support the bucket so as to rotate the bucket around the tilt axis;
- a bucket tilt angle sensor configured to detect a tilt angle of the bucket in the direction;
- and
- a tilt angle controller configured to control adjusting the tilt angle,
- wherein the tilt angle controller adjusts the tilt angle by automatic control of the tilt mechanism so that a bucket line of the bucket becomes parallel to a target excavation surface.

- an arm rotatably attached to a boom rotatably attached to a revolving body, said arm being rotatable relative to the boom on a plane perpendicular to a horizontal plane;
- a bucket rotatably attached to the arm;
- a tilt mechanism including a tilt axis that extends on the plane and is configured to rotatably support the bucket around the tilt axis;
- a bucket tilt angle sensor configured to detect a tilt angle of the bucket in the direction;
- and
- a tilt angle controller configured to control adjusting the tilt angle,
- wherein the tilt angle controller adjusts the tilt angle by automatic control of the tilt mechanism so that a bucket line of the bucket becomes parallel to a target excavation surface, and
- wherein the automatic control of the tilt mechanism is enabled upon receiving an instruction generated by a switch action of an operator.

- an arm rotatably attached to a boom rotatably attached to a revolving body, said arm being rotatable relative to the boom on a plane perpendicular to a horizontal plane;
- a bucket rotatably attached to the arm;
- a tilt mechanism including a tilt axis that extends on the plane and is configured to rotatably support the bucket around the tilt axis;
- a bucket tilt angle sensor configured to detect a tilt angle of the bucket in the direction;
- and
- a tilt angle controller configured to control adjusting the tilt angle,
- wherein the tilt angle controller adjusts the tilt angle by automatic control of the tilt mechanism so that a bucket line of the bucket becomes parallel to a target excavation surface, and
- wherein the automatic control of the tilt mechanism is disabled upon detecting that a distance from a working part of the bucket and the target excavation surface is equal or more than a predetermined distance.
