Abstract
An excavator includes a lower traveling body; an upper turning body mounted on the lower traveling body; an attachment attached to the upper turning body; an attitude detecting device configured to detect an attitude of the attachment including a bucket; and a control device configured to control a toe angle of a toe of the bucket with respect to an excavation ground, based on a transition of the attitude of the attachment, information relating to a present shape of the excavation ground, and an operation content of an operation device relating to the attachment.
Claims11
An excavator comprising:
- a lower traveling body;
- an upper turning body mounted on the lower traveling body;
- an attachment attached to the upper turning body;
- an attitude sensor configured to detect an attitude of the attachment including a bucket;
- and
- a hardware processor configured to change a toe angle of the bucket with respect to a present shape of an excavation ground as a shape of the excavation ground changes during the bucket excavating the excavation ground, based on the attitude of the attachment detected by the attitude sensor and information relating to the present shape of the excavation ground, the toe angle being an angle of a toe of the bucket to the excavation ground, the present shape of the excavation ground being an actual shape of the excavation ground presently below the attachment.
An excavator comprising:

- an upper turning body mounted on the lower traveling body;
- an attachment attached to the upper turning body;
- an attitude sensor configured to detect an attitude of the attachment including a bucket;
- and
- a hardware processor configured to change a toe angle of the bucket with respect to a present shape of an excavation ground while a toe of the bucket is inserted into the excavation ground, based on the attitude of the attachment detected by the attitude sensor and information relating to the present shape of the excavation ground, the toe angle being an angle of the toe of the bucket to the excavation ground, the present shape of the excavation ground being an actual shape of the excavation ground presently below the attachment.

- an upper turning body mounted on the lower traveling body;
- an attachment attached to the upper turning body;
- an attitude sensor configured to detect an attitude of the attachment including a bucket;
- and
- a hardware processor configured to change a toe angle of the bucket according to a shape of an excavation ground while the bucket is moved through the excavation ground, based on the attitude of the attachment detected by the attitude sensor and information relating to a present shape of the excavation ground, the toe angle being an angle of a toe of the bucket to the excavation ground, the present shape of the excavation ground being an actual shape of the excavation ground presently below the attachment.
