Abstract

An exhaust system of an agricultural product container includes a first media screen configured to be coupled to the agricultural product container. The first media screen includes a first plurality of apertures. The first media screen is configured to block a granular product from entering the exhaust system and enabling an air flow into the exhaust system. The exhaust system includes a diffuser having a first diffuser aperture configured to diffuse the air flow in a downward direction. The exhaust system further includes a passage fluidly coupled between the first media screen and the diffuser. The passage is configured to selectively guide the air flow from the first media screen toward the diffuser.

First claim

The invention claimed is:

1. An exhaust system of an agricultural product container, comprising:
a first media screen configured to be coupled to the agricultural product container, wherein the first media screen comprises a first plurality of apertures, wherein the first media screen is configured to block a granular product from entering the exhaust system and to enable an air flow into the exhaust system;
a second media screen parallel to the first media screen, wherein the second media screen comprises a second plurality of apertures, wherein the second plurality of apertures is offset from the first plurality of apertures;
a diffuser comprising a first diffuser aperture configured to diffuse the air flow in a downward direction; and
a passage fluidly coupled between the first media screen and the diffuser, wherein the passage is configured to selectively guide the air flow from the first and second media screens toward the diffuser.

2. The exhaust system of claim 1 , wherein the diffuser comprises a second diffuser aperture, wherein the first diffuser aperture is closer to the passage and has a smaller area, and the second diffuser aperture is farther from the passage and has a larger area.

3. The exhaust system of claim 1 , comprising an exhaust valve coupled between the passage and the diffuser, wherein the exhaust valve is configured to enable the air flow to flow into the diffuser when in an open position and to block the air flow from flowing into the diffuser when in a closed position.

4. The exhaust system of claim 3 , comprising an exhaust valve handle coupled to the exhaust valve, wherein the exhaust valve handle is configured to enable an operator to move the exhaust valve between the open position and the closed position by rotating the exhaust valve handle.

5. The exhaust system of claim 4 , wherein the exhaust valve is configured to move to the open position when the exhaust valve handle is rotated in a first rotation direction and axially translated in a first translation direction.

6. The exhaust system of claim 5 , wherein the exhaust valve is configured to move to the closed position when the exhaust valve handle is axially translated in a second translation direction, opposite the first translation direction, and rotated in a second rotation direction, opposite the first rotation direction.

7. The exhaust system of claim 1 , comprising a third media screen parallel to the first media screen and the second media screen, wherein the third media screen has a third plurality of apertures, wherein the third plurality of apertures is offset from the second plurality of apertures.

8. An exhaust system of an agricultural product container, comprising:
a first media screen configured to be coupled to the agricultural product container, wherein the first media screen comprises a first plurality of apertures, wherein the first media screen is configured to block a granular product from entering the exhaust system and to enable an air flow into the exhaust system in a first direction;
a diffuser comprising a first diffuser aperture configured to diffuse the air flow; and
a passage fluidly coupled between the first media screen and the diffuser, wherein the passage is configured to selectively guide the air flow from the first media screen toward the diffuser by directing the air flow in a second direction, different from the first direction.

9. The exhaust system of claim 8 , wherein the diffuser comprises a second diffuser aperture, wherein the first diffuser aperture is closer to the passage and has a smaller area, and the second diffuser aperture is farther from the passage and has a larger area.

10. The exhaust system of claim 8 , comprising an exhaust valve coupled between the passage and the diffuser, wherein the exhaust valve is configured to enable the air flow to flow into the diffuser when in an open position and to block the air flow from flowing into the diffuser when in a closed position.

11. The exhaust system of claim 10 , comprising an exhaust valve handle coupled to the exhaust valve, wherein the exhaust valve handle is configured to enable an operator to move the exhaust valve between the open position and the closed position by rotating the exhaust valve handle.

12. The exhaust system of claim 11 , wherein the exhaust valve is configured to move to the open position when the exhaust valve handle is rotated in a first rotation direction and axially translated in a first translation direction.

13. The exhaust system of claim 12 , wherein the exhaust valve is configured to move to the closed position when the exhaust valve handle is axially translated in a second translation direction, opposite the first translation direction, and rotated in a second rotation direction, opposite the first rotation direction.

14. The exhaust system of claim 8 , wherein the passage is configured to direct the air flow to exit the passage in a third direction, opposite the first direction.

15. The exhaust system of claim 8 , wherein the first direction comprises a lateral direction and the second direction comprises a downward direction.

16. An exhaust system of an agricultural product container, comprising:
a first media screen configured to be coupled to the agricultural product container, wherein the first media screen comprises a first plurality of apertures, wherein the first media screen is configured to block a granular product from entering the exhaust system and to enable an air flow into the exhaust system;
a diffuser comprising a first diffuser aperture configured to diffuse the air flow in a downward direction;
a passage fluidly coupled between the first media screen and the diffuser, wherein the passage is configured to selectively guide the air flow from the first media screen toward the diffuser;
an exhaust valve system comprising a stem and a valve, wherein the valve is coupled to the stem on a first longitudinal end of the stem, and wherein the exhaust valve system is configured to selectively control air flow from the passage to the diffuser; and
an exhaust valve handle coupled to a second longitudinal end of the stem, opposite the first longitudinal end, wherein the exhaust valve handle is configured to enable an operator to move the exhaust valve system between an open position and a closed position by actuating the exhaust valve handle.

17. The exhaust system of claim 16 , wherein the valve, the exhaust valve handle, and the stem are coupled such that linear actuation of the exhaust valve handle causes linear movement of the valve.

18. The exhaust system of claim 16 , wherein the first media screen is configured to enable the air flow into the exhaust system in a first direction, and wherein the passage is configured to selectively guide the air flow from the first media screen toward the diffuser by directing the air flow in a second direction, different from the first direction.

19. The exhaust system of claim 18 , wherein the passage is configured to direct the air flow to exit the passage in a third direction, opposite the first direction.

20. The exhaust system of claim 18 , wherein the first direction comprises a lateral direction and the second direction comprises a downward direction.
