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 agricultural system, comprising:
an agricultural product container configured to hold a granular product, wherein the agricultural product container comprises:
a plurality of inlet tubes configured to supply the granular product to an interior of the agricultural product container by guiding an air flow entraining the granular product into the interior of the agricultural product container; and
an exhaust system comprising an exhaust valve configured to move between an open position and a closed position to selectively vent the agricultural product container by:
constantly blocking the air flow through the exhaust system while the exhaust valve is in the closed position; and
enabling the air flow through the exhaust system while the exhaust valve is in the open position.

2. The agricultural system of claim 1 , wherein the exhaust system comprises:
a media screen coupled to a body of the agricultural product container, wherein the media screen comprises a first plurality of apertures, and the media screen is configured to block the granular product from entering the exhaust system and to enable the air flow into the exhaust system;
a diffuser comprising a diffuser aperture configured to diffuse the air flow in a downward direction; and
a passage fluidly coupled between the media screen and the diffuser, wherein the passage is configured to guide the air flow from the media screen toward the diffuser.

3. The agricultural system of claim 1 , wherein the plurality of inlet tubes enter a body of the agricultural product container on a first side, and the exhaust system is coupled to the body of the agricultural product container on a second side, wherein the first side is opposite from the second side.

4. The agricultural system of claim 1 , wherein the exhaust system comprises a handle configured to selectively move the exhaust valve between the open and closed positions to control the air flow through the exhaust system.

5. The agricultural system of claim 1 , comprising a fill hopper fluidly coupled to the plurality of inlet tubes, wherein the fill hopper is configured to receive the granular product and to entrain the granular product in the air flow.

6. The agricultural system of claim 1 , wherein the granular product comprises seeds, fertilizer, or a mixture of seeds and fertilizer.

7. The agricultural system of claim 1 , wherein the plurality of inlet tubes comprises a first inlet tube that extends a first distance into a body of the agricultural product container and a second inlet tube that extends a second distance into the body of the agricultural product container, wherein the first distance is different from the second distance.

8. An agricultural system, comprising:
an agricultural product container configured to hold a granular product, wherein the agricultural product container comprises:
a plurality of inlet tubes configured to supply the granular product to an interior of the agricultural product container by guiding an air flow entraining the granular product into the interior of the agricultural product container; and
an exhaust system comprising an exhaust valve configured to move between an open position and a closed position to selectively constantly block the air flow through the exhaust system while the exhaust valve is in the closed position and to enable the air flow through the exhaust system while the exhaust valve is in the open position to vent the agricultural product container.

9. The agricultural system of claim 8 , wherein the exhaust system comprises a handle configured to selectively move the exhaust valve between the open and closed positions to control the air flow through the exhaust system.

10. The agricultural system of claim 8 , wherein the exhaust system comprises:
a media screen coupled to a body of the agricultural product container, wherein the media screen comprises a first plurality of apertures, and the media screen is configured to block the granular product from entering the exhaust system and to enable the air flow into the exhaust system;
a diffuser comprising a diffuser aperture configured to diffuse the air flow in a downward direction; and
a passage fluidly coupled between the media screen and the diffuser, wherein the passage is configured to guide the air flow from the media screen toward the diffuser.

11. The agricultural system of claim 8 , wherein the plurality of inlet tubes enter a body of the agricultural product container on a first side, and the exhaust system is coupled to the body of the agricultural product container on a second side, wherein the first side is opposite from the second side.

12. The agricultural system of claim 8 , wherein the plurality of inlet tubes comprises a first inlet tube that extends a first distance into a body of the agricultural product container and a second inlet tube that extends a second distance into the body of the agricultural product container, wherein the first distance is different from the second distance.

13. The agricultural system of claim 8 , wherein the plurality of inlet tubes are configured to supply the granular product at different locations within the interior of the agricultural product container.

14. The agricultural system of claim 8 , comprising a fill hopper fluidly coupled to the plurality of inlet tubes, wherein the fill hopper is configured to receive the granular product and to entrain the granular product in the air flow.
