摘要：
The invention relates to agricultural engineering and can be used in the design of the combine harvester. The problem to be solved by the utility model, - the distribution of the cleaning air flow width depending on the load thresher and improving the quality of the cleaning during operation of a combine harvester. The technical result - the reduction of grain losses. Said technical result is achieved by that in the known purification Harvester consisting stryasnuyu board, the upper and lower louver sieve, the upper and the lower sieve box and fan, in which the upper sieve pan is provided with a non-adjustable guide boards, and the bottom sieve pan is provided with an adjustable tilt guide board, in which unregulated guide upper sieve box board and adjustable angle of inclination of the lower guide board sieve box is made of two parts, a ach of which consists of the flaps having the ability to move, fixed on the axle and is telescopically folded in packages that are installed in the central portion or purification, or its edges, or along the entire cleaning width.
