SPECIAL CHARACTERISTICS OF GLEANER COMBINE HARVESTERS

Nowadays Gleaner company offers two series of combine harvesters S8 and S9, which uses an original and unique in the world circuit of grain mass threshing and separating by transversely located rotor. The grain mass from header platform climbs through inclined conveyor, which delivers it to the rotor. Then it is captivated by rotor, is threshed, is separated and moving to the left side of combine is ejected from the threshing device by blade thrower. Two distribution augers located under rotor cover supply threshed heap on rubberized roller-boosters that throw it throw air flow for cleaning. Experts of the "Gleaner" company note following advantages of its combine harvesters: - significant reserve of power: the difference between the maximum and the nominal capacity is 23-56 kW, and for analogues - 33-49 kW; - the location of the combine engine is rear, which provides better weight distribution, availability for maintenance and repair, reduction of noise and vibration in the cabin; - feed of grain mass for threshing is done without change of direction, which affects the quality of threshing; - threshing and separation occurs along the entire circumference of the rotor; - the process of grain heap cleaning is done in two stages: the preair stream and at sieves; - in comparison with the analogues it has the same diameter of the rotor but less length, large hopper capacity (except of harvesters S 680 of the company John Deere) and the performance of the unloading auger; - the smaller mass of the harvesters in comparison with analogues, which reduces the power loss on movement and soil compaction.
