Patent Searching and Data


Title:
RADIATOR SCREENS
Document Type and Number:
WIPO Patent Application WO/2012/095689
Kind Code:
A3
Abstract:
A radiator screen arrangement (10) for a combine harvester is provided. A screen (12) through which air, which is to pass through a radiator, is drawn by a fan. Rotating means (16) are provided for rotating the screen. Blanking means (18), past which the screen is rotated, provides a blanked off area of the screen which is not subject to the induction pressure of the fan and from which particles can therefore be more easily removed. The arrangement is characterised in that the blanking means has a leading edge (18a) which is of generally spiral shape so that the particles on the outer surface of the screen which enter the blanked-off area can reach the outer periphery (12d) of the rotating screen without being exposed to the induction pressure of the fan and hence have an improved chance of being detached from the screen.
