The intake air distribution system includes an air blower positioned within the interior space of the air filter screen. The air blower includes an inlet positioned to draw air in through the air filter screen and an outlet through which air is exhausted from the blower. A manifold is connected to the outlet of the blower for directing air onto the walls of the air filter screen and out through the air filter screen. ## Claims ### Claim 1 An intake air distribution system for removing contamination from an air filter screen having walls defining an interior space, the intake air distribution system comprising: an air blower positioned within the interior space of the air filter screen, the air blower including an inlet positioned to draw air in through the air filter screen and an outlet through which air is exhausted from the blower; a drive system for rotating the air filter screen relative to the manifold; a belt engaged between a first pulley and the air filter screen, wherein the drive system rotates the air filter screen which consequently rotates the belt, which causes rotation of the first pulley; a pulley belt; a second pulley either engaged to or extending from an input shaft of the blower, the second pulley being attached to the first pulley by the pulley belt such that rotation of the first pulley causes rotation of the second pulley, and rotation of the second pulley results in rotation of the input shaft of the blower, which causes air to be distributed from the inlet to the outlet of the blower; and a manifold extending from the outlet of the blower for directing air onto the walls of the air filter screen and out through the air filter screen. ### Claim 2 (depends on 1) The intake air distribution system of claim 1 further comprising a panel to which the air filter screen is rotatably mounted. ### Claim 3 (depends on 2) The intake air distribution system of claim 2 further comprising a guide roller mounted to the panel, wherein the air filter screen is mounted to the guide roller such that the air filter screen can rotate on the guide roller. ### Claim 4 (depends on 1) The intake air distribution system of claim 1, wherein the first pulley includes a shaft that is rotatably mounted to either the blower or a panel to which the blower is either directly or indirectly mounted. ### Claim 5 (depends on 1) The intake air distribution system of claim 1, wherein the drive system includes a belt connected to the air filter screen for rotating the screen relative to the manifold. ### Claim 6 (depends on 1) The intake air distribution system of claim 1, wherein the walls of the air filter screen include a circular wall defining a longitudinal axis and a side wall extending from a circumference of the circular wall. ### Claim 7 (depends on 6) The intake air distribution system of claim 6, wherein the inlet of the blower is positioned adjacent the circular wall of the air filter screen. ### Claim 8 (depends on 6) The intake air distribution system of claim 6, wherein the side wall of the air filter screen includes an undulating portion. ### Claim 9 (depends on 8) The intake air distribution system of claim 8 wherein the manifold includes an undulating surface that is interlaced with the undulating portion of the air filter screen, such that a crest of the undulating surface is aligned with a trough of the undulating portion and a trough of the undulating surface is aligned with a crest of the undulating portion. ### Claim 10 (depends on 5) The intake air distribution system of claim 5 wherein the manifold includes perforations that register with the side wall and the circular wall of the air filter screen. ### Claim 11 An intake air distribution system for an agricultural vehicle, the intake air distribution system comprising: an air filter screen having walls defining an interior space, the walls of the air filter screen including a circular wall defining a longitudinal axis and a side wall extending from a circumference of the circular wall, wherein the side wall of the air filter screen includes an undulating portion; an air blower positioned within the interior space of the air filter screen, the air blower including an inlet positioned adjacent the circular wall of the air filter screen to draw air in through the air filter screen and an outlet through which air is exhausted from the blower; and a manifold extending from the outlet of the blower for exhausting air through the walls of the air filter screen to remove contamination from the air filter screen, the manifold including: an undulating surface that is interlaced with the undulating portion of the air filter screen, such that a crest of the undulating surface is aligned with a trough of the undulating portion and a trough of the undulating surface is aligned with a crest of the undulating portion; and perforations that register with the side wall and the circular wall of the air filter screen. ### Claim 12 (depends on 11) The intake air distribution system of claim 11, further comprising a drive system for rotating the air filter screen relative to the manifold. ### Claim 13 (depends on 11) The intake air distribution system of claim 11 further comprising a panel to which the air filter screen is rotatably mounted. ### Claim 14 (depends on 13) The intake air distribution system of claim 13 further comprising a guide roller mounted to the panel, wherein the air filter screen is mounted to the guide roller such that the air filter screen can rotate on the guide roller. ### Claim 15 An intake air distribution system for removing contamination from an air filter screen having walls defining an interior space, the intake air distribution system comprising: an air blower positioned within the interior space of the air filter screen, the air blower including an inlet positioned to draw air in through the air filter screen and an outlet through which air is exhausted from the blower; a manifold extending from the outlet of the blower for directing air onto the walls of the air filter screen and out through the air filter screen, the manifold including perforations that register with the side wall and the circular wall of the air filter screen; and a drive system for rotating the air filter screen relative to the manifold, the drive system including a belt connected to the air filter screen for rotating the screen relative to the manifold.
