Title: Combine Systems and Components
As shown in the attached illustrations and described below, various operational systems and components of an agricultural combine and/or header, are disclosed.
Convex Diffuser Screen
Figures 1‐3 schematically illustrate air flow distribution through cooling cores of combine cooling system, with increased restriction at the center of the cooling cores in order to force the air to the outer portion of the cooling cores and thus increase the cooling core performance.
The concept is to place an air deflector in the central air flow area of the radiator package to divert air flow to the outer areas of the cooling cores. The air deflector can be fixed or mounted on a bearing to permit fins to impart a spinning motion to the deflector which would further enhance the air redistribution effect. The deflector can also be curved or cone shaped to gradually change the direction of the air flow from radial to axial direction into the cooling cores. Additionally, the deflector can be perforated or made from screen material to permit a portion of the axial air flow to enter the cooling cores directly down stream of the deflector. The size of the perforations or screen mesh density can be adjusted to balance the air flow more evenly over the entire surface area of the cooling cores
Rotating Brush in Enclosed Vacuumed Environment to Clean Rotary Screen
Figures 4‐5 schematically illustrate a rotary screen brush arrangement that cleans the rotary screen from crop debris to better cleanse the air used to cool the engine powering the combine and to help prevent the combine from overheating.
A brush rotates in an enclose that that has air being ducted away from the screen. Brush will remove material from screen and the ducted air flow will move the debris away from the screen. Brush can be driven mechanically or electrically with or against the direction of the screen and at a speed equal to or different from the screen.
Rotary Brush on the Outlet Air Side of the Rotary Screen
Figures 6‐7 schematically illustrate a rotary screen brush arrangement with a rotary brush on the backside of the rotary screen to push debris collected on the rotary screen off.
The concept is to install a rotating brush on the back side of the screen. The brush can operate the same direction as the screen or in the opposite direction. The brush would be drive either by the screen, mechanically, or electrically. The brush would be used to disturb the debris collecting on the ...
