Air cooling system for drive engine of an automotive agricultural machine
First Claim
1. An air cooling system for the drive engine of an automotive agricultural machine with spaced-apart radiators, an exhaust system and an air compartment having side walls and end walls characterized in that two fans (10, 11) are mounted on a common drive shaft (12) behind a drive motor (3) one of said fans located in each end wall of the air compartment (4), each side wall being formed by one of said radiators (6, 7), a pivotal air-deflection plate (16) mounted between the fans (10, 11) so as to always be diagonal to the radiators, and the air compartment being divided into two subcompartments, the walls of each subcompartment always formed by one radiator (6, 7), one fan (10, 11) and the air-deflection plate (16), and between the drive engine (3) and the fans (10, 11) there is a partition (17) extending down from an upper machine wall (18) to the common drive shaft (12) and to both sides of the partition (17) there are openings (19, 20) in the upper machine wall (18) and between the air compartment (4) and the upper machine wall (18) there is the exhaust system (21) of the drive engine (3).

Abstract
The invention relates to an air-cooling system for a drive engine of an automotive agricultural machine, in particular a field chopper.
It is a goal of this invention to provide a forced-air cooling system with considerable cooling capacity and a good cleaning effect for screens and the engine compartment. This object is attained by providing a cooling system where the warm air is blown upwardly and selectively to one side, a reversal of the cooling-air stream for cleaning the screens being possible, and a forced-air ventilating of the engine compartment being assured.
The basis of the invention is that an air compartment is provided with two fans mounted between a pair of radiators each behind a respective screen. An air-deflector plate is so arranged in the air compartment that it is possible to alternate the fans between radiators so that the cooling-air stream can pass in either direction through each of the radiators and screens. One fan meanwhile blows cooling air into the engine compartment, which air escapes upwardly through openings in the upper machine wall.
