COMBINE FOR HARVESTING GRAIN CROPS BY STRIPPING AT GRASSROOTS

摘要

FIELD: agriculture.;SUBSTANCE: combine for harvesting grain crops by stripping at the grassroots comprises a header for stripping and threshing crops at the grassroots, hung on the combine thresher by the feed elevator with two conveyors of grain heap, cleaning the thresher with fan, the shaker pan, the upper sieve, the sieve pan with a chute board and the lower sieve, an elevator for transporting tailings, the finish threshing device, the hopper for grain collecting, mounted on the frame of the caterpillar truck under the sieve pan, the screw extruder with a receiving chamber, a motor unit. In front of the combine thresher under the feed elevator an additional fan is mounted, the air flow of which is directed on the top and along the work surface of the shaker pan and passes through the grain heap falling from two conveyors of the feed elevator on the work surface of the shaker pan. The screw extruder is mounted to the frame of the caterpillar truck so that its longitudinal axis coincides with the longitudinal axis of the combine, and the receiving chamber is communicated with an air flow of the additional fan.;EFFECT: improvement of performance of the combine with the decrease of anthropogenic impact on the soil.;3 cl, 4 dwg
