Abstract

A work vehicle has a cab. A protruding portion is located on an upper side of the cab and protrudes rearward relative to a rear portion of the cab. A surveillance camera is arranged on a rear side of the protruding portion. A surveillance camera is arranged above the surveillance camera, and an optical axis is inclined posterosuperiorly relative to an optical axis of the surveillance camera.

First claim

The invention claimed is:

1. A work vehicle having a cab, comprising:
a protruding portion on an upper side of said cab, which protrudes rearward from a rear portion of said cab;
a first image pick-up apparatus arranged on a rear side of said protruding portion; and
a second image pick-up apparatus arranged above said first image pick-up apparatus, which has an optical axis inclined posterosuperiorly relative to an optical axis of said first image pick-up apparatus, wherein
said protruding portion serves as an air conditioner,
said air conditioner includes
a heat exchanger,
a top cover arranged above said heat exchanger, and
a fan arranged between said heat exchanger and said top cover and having a rotation shaft extending along an upward/downward direction of said work vehicle, and

said first image pick-up apparatus is arranged in rear of said fan.

2. The work vehicle according to claim 1 , wherein said fan has an upper plate having an opening, and
both of said first image pick-up apparatus and said second image pick-up apparatus are arranged at a position lower than a height position of said upper plate of said fan.

3. The work vehicle according to claim 1 , further comprising a rectification member having two diverter baffles, wherein
said two diverter baffles have front ends connected to each other, an interval between said two diverter baffles increases from front to rear in a plan view, and said second image pick-up apparatus is located between said two diverter baffles in a plan view.

4. The work vehicle according to claim 1 , wherein
an upper surface of said top cover is higher in height position than an upper surface of said cab, and
a connection portion between the upper surface of said top cover and the upper surface of said cab includes a step.

5. The work vehicle according to claim 1 , wherein
said top cover has a top plate and a rectification portion extending downward from a lower surface of said top plate, and
said rectification portion is formed integrally with said top plate.

6. The work vehicle according to claim 5 , further comprising an outlet cover arranged in rear of said fan and having an outlet, wherein
said rectification portion has an air shield portion extending between said fan and said outlet cover.

7. The work vehicle according to claim 1 , wherein
said top cover has an exhaust port passing through said top cover.

8. The work vehicle according to claim 1 , wherein
while said work vehicle is arranged on a horizontal ground, the optical axis of said first image pick-up apparatus is inclined downward with respect to the horizontal and the optical axis of said second image pick-up apparatus is inclined upward with respect to the horizontal.

9. The work vehicle according to claim 1 , further comprising:
a first display apparatus for displaying an image picked up by said first image pick-up apparatus; and
a second display apparatus for displaying an image picked up by said second image pick-up apparatus.

10. The work vehicle according to claim 9 , wherein
said cab has an operator seat in inside, and
said first display apparatus is arranged in front of said operator seat and said second display apparatus is arranged in a sidewall of said cab located lateral to said operator seat.

11. The work vehicle according to claim 9 , wherein
said cab has an operator seat in inside, and
said first display apparatus is arranged in front of said operator seat and said second display apparatus is arranged in a sidewall of said cab located above said operator seat.

12. A work vehicle having a cab, comprising:
a protruding portion on an upper side of said cab, which protrudes rearward from a rear portion of said cab;
a first image pick-up apparatus arranged on a rear side of said protruding portion;
a second image pick-up apparatus arranged above said first image pick-up apparatus, which has an optical axis inclined posterosuperiorly relative to an optical axis of said first image pick-up apparatus; and
a rectification member having two divertor baffles, wherein
said two diverter baffles have front ends connected to each other, an interval between said two diverter baffles increases from front to rear in a plan view, and said second image pick-up apparatus is located between said two diverter baffles in a plan view.
