Abstract

A work vehicle includes a reducing agent tank, a battery, a reducing agent tank mounting member, a battery cover and a first guide member. The battery and the tank are positioned in a row. The mounting member has a bottom plate, and a partition plate extending upward from the bottom plate between the tank and the battery. The tank is mounted on the bottom plate. The battery cover has an upper plate above the battery, and a side plate extending downward from a side of the upper plate between the tank and the battery. The first guide member extends from the side plate toward the tank and slopes downward. Preferably, a first end of a second guide member disposed below the first guide member is positioned closer to the battery than a distal end of the first guide member, with the second guide member sloping downward toward the tank.

Claims

1. A work vehicle comprising:

a reducing agent tank;

a battery disposed in a row with the reducing agent tank with a gap therebetween;

a reducing agent tank mounting member having a bottom plate with reducing agent tank mounted thereon, and a partition plate extending upward from the bottom plate and positioned between the reducing agent tank and the battery;

a battery cover having an upper plate positioned above the battery, and a side plate extending downward from a side of the upper plate and positioned between the reducing agent tank and the battery;

a first guide member extending from the side plate toward the reducing agent tank, the first guide member sloping downward; and

a second guide member disposed below the first guide member, the second guide member sloping downward toward the reducing agent tank,

the second guide member having a first end positioned closer to the battery than a distal end of the first guide member.

2. The work vehicle according to claim 1, wherein

the second guide member further has a second end positioned closer to the reducing agent tank than the partition plate.

3. The work vehicle according to claim 1, further comprising:

a partitioning member extending between the second guide member and the partition plate.

4. The work vehicle according to claim 3, wherein

the partitioning member hangs down from the second guide member, and

a lower end of the partitioning member is positioned closer to the reducing agent tank than the partition plate and is positioned lower than an upper end of the partition plate.

5. The work vehicle according to claim 3, wherein

the partitioning member is made of rubber.

7. The work vehicle according to claim 2, further comprising:

a partitioning member extending between the second guide member and the partition plate.

8. The work vehicle according to claim 7, wherein

the partitioning member hangs down from the second guide member, and

a lower end of the partitioning member is positioned closer to the reducing agent tank than the partition plate and is positioned lower than an upper end of the partition plate.

9. The work vehicle according to claim 8, wherein

the partitioning member is made of rubber.

10. The work vehicle according to claim 7, wherein

the partitioning member is made of rubber.

11. The work vehicle according to claim 4, wherein

the partitioning member is made of rubber.

6. A work vehicle comprising:

a reducing agent tank;

a battery disposed in a row with the reducing agent tank with a gap therebetween;

a reducing agent tank mounting member having a bottom plate with the reducing agent tank mounted thereon, and a partition plate extending upward from the bottom plate and positioned between the reducing agent tank and the battery;

a battery cover having an upper plate positioned above the battery, and a side plate extending downward from a side of the upper plate and positioned between the reducing agent tank and the battery; and

a first guide member extending from the side plate toward the reducing agent tank, the first guide member sloping downward,

a distal end of the first guide member being positioned closer to the reducing agent tank than the partition plate.
