摘要：
The claimed utility model relates to agricultural engineering and is intended for use in air-screen cleaning of grain heaps of grain harvesters in the process of threshing grain crops. The objective of the claimed utility model is to improve the efficiency of the air-screen separator of the grain heap, reduce weed impurities and losses for cleaning, reduce grain crushing, simplify the design and improve the reliability of the mechanism. The technical result is achieved due to the fact that in the construction of the claimed utility model comprising a transport board, a fan, a movable finger grate, upper and lower adjustable louver sieves, an upper sieve extension, a fixed finger grid, two links and a transverse beam, the fingers of the fixed finger grid are offset relative to the fingers of the movable finger grid so that the fingers of the movable finger grating pass between the fingers of the fixed finger grid, and both arms are pivotally mounted on a cross beam rigidly attached to the side panels of the thresher and drive the movable finger grate by moving the transport board. The technical result consists in increasing the efficiency of the air-grinding separator of the grain heap of a combine harvester, reducing weed impurities, reducing the grain crushing, reducing the losses due to cleaning, increasing the productivity of the combine due to unloading of the cleaning and the system of the strangler, simplifying the design and, in general, mechanism. that the fingers of the movable finger grating pass between the fingers of the fixed finger grid, and both arms are hingedly mounted on a transverse beam rigidly attached to the side panels of the thresher and drive the movable finger grate by moving the transport plate. The technical result consists in increasing the efficiency of the air-grinding separator of the grain heap of a combine harvester, reducing weed impurities, reducing the grain crushing, reducing the losses due to cleaning, increasing the productivi
