Abstract

A vehicle body cover of a work vehicle is provided with an outside ventilation cover part and an inside ventilation cover part. The outside ventilation cover part has outside ventilation holes that communicate with an external space. The outside ventilation cover part is disposed in an inclined manner with respect to the vertical direction. The inside ventilation cover part is disposed to face the outside ventilation holes on the inside of the outside ventilation cover part. The inside ventilation cover part has a rain gutter part and a ventilation part. The rain gutter part is configured to receive water entering from the outside ventilation holes. The ventilation part has inside ventilation holes that communicate with a space on the inside of the inside ventilation cover part. The ventilation part is disposed above the rain gutter part.

First claim

1 . A vehicle body cover of a work vehicle, the vehicle body cover comprising:
an outside ventilation cover part having an outside ventilation hole that communicates with an external space, the outside ventilation cover part being disposed in an inclined manner with respect to the vertical direction; and an inside ventilation cover part disposed to face the outside ventilation hole on an inside of the outside ventilation cover part; the inside ventilation cover part including
a rain gutter part configured to receive water that enters from the outside ventilation hole; and
a ventilation part having an inside ventilation hole that communicates with a first space on an inside of the inside ventilation cover part, the ventilation part being disposed above the rain gutter part.

2 . The vehicle body cover of the work vehicle according to claim 1 , wherein
the outside ventilation cover part includes
an inclined surface part that includes the outside ventilation hole, and
an eave part that covers the outside ventilation hole from an outside of the vehicle body cover.

3 . The vehicle body cover of the work vehicle according to claim 2 , wherein
the inclined surface part and the eave part are formed in an integrated manner.

4 . The vehicle body cover of the work vehicle according to claim 1 , wherein
the rain gutter part is disposed to overlap the outside ventilation hole as seen in a plan view.

5 . The vehicle body cover of the work vehicle according to claim 1 , wherein
the ventilation part is disposed to overlap the outside ventilation hole as seen in a horizontal view.

6 . The vehicle body cover of the work vehicle according to claim 1 , wherein
the outside ventilation cover part has a draining hole that communicates with a second space between the rain gutter part and the outside ventilation cover part.

7 . The vehicle body cover of the work vehicle according to claim 1 , wherein
the rain gutter part is disposed to be inclined downward toward the outside ventilation cover part.

8 . The vehicle body cover of the work vehicle according to claim 1 , wherein
the first space between the outside ventilation cover part and the inside ventilation cover part is open at the side surfaces of the outside ventilation cover part and the inside ventilation cover part.

9 . The vehicle body cover of the work vehicle according to claim 1 , wherein
the ventilation part has a plurality of ventilation holes that includes the inside ventilation hole.

10 . The vehicle body cover of the work vehicle according to claim 1 , wherein
the inside ventilation cover part further has a guiding member connected to the inside ventilation hole; and the guiding member guides a flow of air that passes through the inside ventilation hole to the inside of the inside ventilation cover part.

11 . The vehicle body cover of the work vehicle according to claim 1 , further comprising
a plate-like member disposed between the outside ventilation hole and the inside ventilation hole.

12 . The vehicle body cover of the work vehicle according to claim 1 , further comprising
a first exterior cover having an opening, disposed in an inclined manner with respect to the vertical direction, and being a separate body from the outside ventilation cover part, the outside ventilation cover part and the inside ventilation cover part provided in an integrated manner with each other to be configured as a ventilation cover unit; the ventilation cover unit is attached to the first exterior cover and closing the opening.

13 . The vehicle body cover of the work vehicle according to claim 1 , further comprising
a second exterior cover disposed under the outside ventilation cover part and disposed in an inclined manner with respect to the vertical direction; the inclination angle with respect to the vertical direction of the outside ventilation cover part being greater than the inclination angle with respect to the vertical direction of the second exterior cover.

14 . A work vehicle comprising the vehicle body cover according to claim 1 .

15 . The work vehicle according to claim 14 , further comprising
a cab; an engine room having the vehicle body cover and disposed to the rear of the cab, an engine disposed inside the engine room; a first exhaust processing device disposed over the engine; and a second exhaust processing device disposed over the engine.
