SELF-PROPELLED GRAIN COMBINE HARVESTER

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to agricultural machinery industry. The self-propelled grain combine harvester comprises a hopper 2, an engine 3 mounted behind it, a thresher 6, a grinder 9 and an unloading auger 11. From the output shaft of the engine 3 a pump of chassis hydraulic gear 4, a hydraulic system pump 5, a grinder 9, a thresher 6 and an unloading auger 11 of the hopper 2 are actuated by the direct circuit of the belt drives. The unloading auger 11 is located inside the drive circuit of the thresher 6. The drives of the thresher 6 and the grinder 9 are actuated by the belt idlers. The slack side 7 over the neck 12 of the unloading auger 11 is held by the additional run-around roller 13 with the variable position of the proportional to the belt stretching. The axis 14 of the belt idler lever 8 can be located on the run-around roller bracket 13 or on the thresher housing.;EFFECT: invention provides performance of the belt drive in the allowed range of the belt stretching.;1 dwg
