Definitions
- the present invention relates to a vehicle body cover and a work vehicle.
- the vehicle body cover of the work vehicle is provided with ventilation holes for ventilation.
- ventilation holes for ventilation For example, in the vehicle of Patent Document 1, a vent hole is provided on the side surface of the engine compartment, and the outside air for cooling is taken into the engine compartment via the vent hole.
- the operator of the work vehicle performs the operation of the work machine or the operation of the vehicle while viewing the surroundings of the vehicle. Therefore, the work vehicle is required to have good visibility.
- the shape of the vehicle body cover affects visibility. For example, by forming a part of the vehicle body cover into an inclined shape, the blind spot can be reduced and visibility can be improved.
- An object of the present invention is to provide a vehicle body cover and a work vehicle that can obtain good air permeability and suppress visibility of water while improving visibility.
- a vehicle body cover for a work vehicle includes an outer ventilation cover portion and an inner ventilation cover portion.
- the outer ventilation cover portion has an outer ventilation hole communicating with an external space.
- the outer ventilation cover portion is disposed to be inclined with respect to the vertical direction.
- the inner ventilation cover portion is disposed to face the outer ventilation hole inside the outer ventilation cover portion.
- the inner ventilation cover part has a rain gutter part and a ventilation part.
- the rain gutter is configured to receive water that has entered through the outer vent.
- the ventilation portion has an inner ventilation hole communicating with the inner space of the inner ventilation cover portion.
- the ventilation part is disposed above the rain gutter part.
- the outer ventilation cover portion is disposed to be inclined with respect to the vertical direction. Thereby, visibility can be improved. Further, the outside air can flow into the vehicle body cover through the outer ventilation hole of the outer ventilation cover part and the inner ventilation hole of the ventilation part. Alternatively, the air in the vehicle body cover can flow out of the vehicle body cover through the inner ventilation hole of the ventilation part and the outer ventilation hole of the outer ventilation cover part. Thereby, favorable air permeability can be obtained. Furthermore, even if water enters from the outer ventilation hole, the rain gutter can receive water. Moreover, since the ventilation part is disposed above the rain gutter part, even if water enters from the outer ventilation hole, it is difficult for water to enter the inner ventilation hole of the ventilation part. As a result, water can be prevented from entering the inside of the vehicle body cover.
- the outer ventilation cover part has an inclined surface part including the outer ventilation hole and a flange part that covers the outer ventilation hole from the outside. In this case, the intrusion of water from the outer ventilation hole can be suppressed.
- the inclined surface portion and the flange portion are formed integrally.
- the outer ventilation cover portion can be easily formed by, for example, pressing.
- the rain gutter portion is disposed so as to overlap the outer vent hole in plan view.
- the water that has entered from the outer ventilation hole can be easily received by the rain gutter.
- the ventilation portion is disposed so as to overlap with the outer ventilation hole when viewed in the horizontal direction.
- the water is less likely to enter the inner ventilation hole of the ventilation portion.
- the air permeability can be improved.
- the outer ventilation cover part has a drain hole communicating with the space between the rain gutter part and the outer ventilation cover part.
- the water that has entered through the outer ventilation hole and received by the rain gutter portion can be easily discharged to the outside through the drain hole.
- the rain gutter part is disposed to be inclined downward toward the outer ventilation cover part.
- the water that has entered the outside vent hole and received by the rain gutter portion can be more easily discharged to the outside through the drain hole.
- the space between the outer ventilation cover portion and the inner ventilation cover portion is open on the side surfaces of the outer ventilation cover portion and the inner ventilation cover portion.
- the space between the outer ventilation cover portion and the inner ventilation cover portion can be easily accessed from the side openings of the outer ventilation cover portion and the inner ventilation cover portion.
- the maintainability of the vehicle body cover can be improved.
- the cleaning nozzle can be easily inserted into the space between the outer ventilation cover part and the inner ventilation cover part from the opening. For this reason, even if a foreign substance enters the space between the outer ventilation cover part and the inner ventilation cover part, it can be easily removed.
- the ventilation part has a plurality of ventilation holes including inner ventilation holes.
- the air permeability can be further improved.
- the inner ventilation cover portion further includes a guide member connected to the inner ventilation hole.
- the guide member guides the air flow through the inner ventilation hole and inward of the inner ventilation cover portion.
- the outside air can be introduced to a desired position by the guide member.
- the apparatus can be effectively cooled by guiding air to the apparatus that requires cooling by the guide member.
- a plate-like member disposed between the outer ventilation hole and the inner ventilation hole is further provided.
- the plate-like member functions as a baffle plate, so that it is difficult for water to enter the inner vent hole. For this reason, even if the inner vent hole is enlarged, the intrusion of water into the inside of the vehicle body cover can be suppressed.
- air permeability can be improved by enlarging an internal ventilation hole. Thus, for example, by guiding more air to a device that requires cooling, the device can be more effectively cooled.
- the vehicle body cover further includes a first exterior cover.
- the first exterior cover has an opening and is disposed to be inclined with respect to the vertical direction.
- the first exterior cover is a separate body from the outer ventilation cover portion.
- the outer ventilation cover portion and the inner ventilation cover portion are integrated with each other to constitute a ventilation cover unit.
- the ventilation cover unit is attached to the first exterior cover and closes the opening.
- the inner ventilation cover part and the outer ventilation cover part can be easily detached from the vehicle body by attaching / detaching the ventilation cover unit to / from the first exterior cover. For this reason, maintainability can be improved.
- the vehicle body cover further includes a second exterior cover.
- the second exterior cover is disposed below the outer ventilation cover portion, and is inclined with respect to the vertical direction.
- the inclination angle of the outer ventilation cover portion with respect to the vertical direction is larger than the inclination angle of the second exterior cover with respect to the vertical direction.
- the inclination angle of the outer ventilation cover portion arranged above the second exterior cover with respect to the vertical direction is larger than the inclination angle of the second exterior cover with respect to the vertical direction. For this reason, visibility can be further improved.
- a work vehicle according to another aspect of the present invention includes the vehicle body cover described above.
- the work vehicle according to this aspect has good air permeability and can suppress water intrusion while improving visibility.
- the work vehicle further includes a cab, an engine room, an engine, a first exhaust treatment device, and a second exhaust treatment device.
- the engine compartment has a vehicle body cover and is disposed behind the cab.
- the engine is disposed in the engine compartment.
- the first exhaust treatment device is disposed above the engine.
- the second exhaust treatment device is disposed above the engine.
- the outer ventilation cover portion is arranged to be inclined with respect to the vertical direction, so that good visibility can be obtained. Furthermore, even if the outer ventilation cover portion is inclined, the inner ventilation cover portion can prevent water from entering the engine compartment.
- the present invention in the vehicle body cover of a work vehicle, it is possible to obtain good air permeability and to suppress water intrusion while improving visibility.
