1. 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 an 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 a 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 a 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; 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; and wherein the first knives provided on the sieve comprise first knife-edges, which rise relative to a plane of the surface of the sieve from a front end, as viewed in the direction of movement, diagonally in the direction of a back end, continuously. |
