Abstract

A deflector attachment is adapted to surround an exhaust outlet provided in a dump body of the machine. The deflector attachment includes a plate member having a curved portion. Exhaust gases exiting the exhaust outlet are adapted to first impact the curved portion. The deflector attachment also includes a pair of side plates spaced apart by the plate member. The deflector attachment further includes an inclined deflecting plate extending between the pair of side plates. The plate member, the pair of side plates, and the inclined deflecting plate define a flow passage for smoothly diverting the exhaust gases exiting the exhaust outlet towards a central portion of the dump body.

First claim

The invention claimed is:

1. A deflector attachment associated with a machine, wherein the deflector attachment is adapted to surround an exhaust outlet provided in a dump body of the machine, the deflector attachment comprising:
a plate member including a curved portion, wherein exhaust gases exiting the exhaust outlet are adapted to first impact the curved portion;
a pair of side plates spaced apart by the plate member; and
an inclined deflecting plate extending between the pair of side plates, wherein the plate member, the pair of side plates, and the inclined deflecting plate define a flow passage for smoothly diverting the exhaust gases exiting the exhaust outlet towards a central portion of the dump body.

2. The deflector attachment of claim 1 , wherein a radius of the curved portion lies between 275 mm and 325 mm.

3. The deflector attachment of claim 1 , wherein the inclined deflecting plate is inclined with respect to a floor of the dump body such that an angle of inclination of the inclined deflecting plate lies between 42 degrees and 48 degrees.

4. The deflector attachment of claim 1 , wherein the exhaust outlet is defined in a floor of the dump body and is proximal to a side wall of the dump body.

5. The deflector attachment of claim 4 , wherein the deflector attachment is welded to the floor.

6. The deflector attachment of claim 4 , wherein a height of the deflector attachment is less than a height of a rib of the floor.

7. The deflector attachment of claim 1 , wherein each of the pair of side plates includes a cut-out portion.

8. The deflector attachment of claim 1 , wherein the machine includes a plurality of deflector attachments.

9. A dump body associated with a machine, the dump body comprising:
a floor defining an exhaust outlet;
a front wall;
a pair of side walls, wherein the floor, the front wall, and the pair of side walls are structured and arranged to define a material collection structure, the exhaust outlet being provided proximal to at least one of the pair of side walls; and
a deflector attachment coupled to the floor and adapted to surround the exhaust outlet, the deflector attachment comprising:
a plate member including a curved portion, wherein exhaust gases exiting the exhaust outlet are adapted to first impact the curved portion;
a pair of side plates spaced apart by the plate member; and
an inclined deflecting plate extending between the pair of side plates, wherein the plate member, the pair of side plates, and the inclined deflecting plate define a flow passage for smoothly diverting the exhaust gases exiting the exhaust outlet towards a central portion of the dump body.

10. The dump body of claim 9 , wherein a radius of the curved portion lies between 275 mm and 325 mm.

11. The dump body of claim 9 , wherein the inclined deflecting plate is inclined with respect to the floor such that an angle of inclination of the inclined deflecting plate lies between 42 degrees and 48 degrees.

12. The dump body of claim 9 , wherein each of the pair of side plates includes a cut-out portion.

13. The dump body of claim 9 , wherein a height of the deflector attachment is less than a height of a rib of the floor.

14. The dump body of claim 9 , wherein the machine includes a plurality of deflector attachments.

15. A deflector attachment associated with a machine, wherein the deflector attachment is adapted to surround an exhaust outlet provided in a dump body of the machine, the deflector attachment comprising:
a plate member including a curved portion, wherein exhaust gases exiting the exhaust outlet are adapted to first impact the curved portion;
a pair of side plates spaced apart by the plate member; and
an inclined deflecting plate extending between the pair of side plates, wherein the plate member and the pair of side plates define a flow passage for smoothly diverting the exhaust gases exiting the exhaust outlet towards a central portion of the dump body.

16. The deflector attachment of claim 15 , wherein the inclined deflecting plate is inclined with respect to a floor of the dump body such that an angle of inclination of the inclined deflecting plate lies between 42 degrees and 48 degrees.

17. The deflector attachment of claim 15 , wherein a radius of the curved portion lies between 275 mm and 325 mm.

18. The deflector attachment of claim 15 , wherein each of the pair of side plates include a cut-out portion.

19. The deflector attachment of claim 15 , wherein the deflector attachment is welded to a floor of the dump body.

20. The deflector attachment of claim 19 , wherein a height of the deflector attachment is less than a height of a rib of the floor.
