Air intake system for cooling air

An air intake system for cooling air, which is fed to at least one heat exchanger, cooling surfaces of assemblies of a self-propelled harvesting machine or both, the air intake system comprising:

• a sieve through which the cooling air flows and which is equipped, on an inlet side, with a device for removing and shredding components of the cooling air adhering on the inlet-side surface of the sieve,
• wherein the device comprises a suction device and a cutting device;
• wherein the cutting device is formed of comb-like elements on the surface of the sieve and on a surface section of the suction device facing the inlet-side surface of the sieve or, the cutting device is formed of a front element connected to the surface section of the suction device;
• wherein the comb-like elements disposed on the surface of the sieve are designed as knives and disposed on support or knife strips oriented transversely thereto;
• wherein at least one of the support strips is equipped with first knives, the knife-edges of which implement a pulling cut;
• and
• wherein the comb-like elements on both end faces of the suction device or of the front element attached thereto are designed as second knives, the knife-edges of which implement a pulling cut.
