Work vehicle having image pick-up apparatus
A work vehicle is capable of readily knowing an amount of soil built up on a front surface of a blade. A motor grader includes a vehicular body frame, a blade, and an image pick-up apparatus. The blade is arranged between a front end of the vehicular body frame and a rear end of the vehicular body frame. The blade is supported on the vehicular body frame. The image pick-up apparatus is arranged in front of the blade. At least a part of the blade is included within an angle of view of the image pick-up apparatus. A revolving operation of the blade is automatically controlled based on the amount of soil built up on the front surface of the blade.
1. A motor grader comprising:
a vehicular body frame that includes a front frame and a rear frame;
a draw bar having one end coupled to the front frame;
a blade arranged between a front end of the vehicular body frame and a rear end of the vehicular body frame and supported on the front frame of the vehicular body frame; and
an image pick-up apparatus arranged in front of the blade, at least a part of a front surface of the blade being included within an angle of view of the image pick-up apparatus, the image pick-up apparatus picking-up at least one image of an amount of soil built up on a front surface of the blade,
wherein the image pick-up apparatus is arranged below the draw bar, and
wherein a revolving operation of the blade is automatically controlled based on the amount of soil built up on the front surface of the blade.
2. The motor grader according to claim 1 , the motor grader further comprising:
a front wheel arranged in front of the blade; and
a rear wheel arranged in rear of the blade.
3. The motor grader according to claim 2 , wherein
the image pick-up apparatus is arranged between the blade and the front wheel.
4. The motor grader according to claim 1 , wherein
at least a lower end of the blade is included in the angle of view of the image pick-up apparatus.
5. The motor grader according to claim 1 , wherein
the image pick-up apparatus includes an optical axis which intersects with the blade.
6. The motor grader according to claim 1 , the motor grader further comprising an articulation cylinder attached between the front frame and the rear frame.
7. The motor grader according to claim 1 , the motor grader further comprising a swing circle arranged below the front frame, the blade is disposed on the swing circle, wherein
the image pick-up apparatus is fixed to a lower surface of the swing circle.
8. The motor grader according to claim 1 ,
wherein the draw bar supporting the blade, and
wherein the image pick-up apparatus is fixed to a lower surface of the draw bar.
9. The motor grader according to claim 7 , wherein the image pick-up apparatus is fixed to a position on the swing circle most distant from the blade.
