General information

The high capacity multi-crop thresher consists of a spike tooth cylinder, three-aspirators, cleaning sieves and feeding system.. For operation the dry crop is fed continuously in feeding hopper, loose or in the form of bundles. Feed rollers provided in the feeding hopper, push the crop into the threshing drum. The beaters or spikes on the threshing cylinder hit the crop and the impact causes detachment of grains from the ear heads of the crop. The straw  and some unthreshed grains move around the cylinder. The rubbing action between the straw, threshing drum and concave threshes the rest of grains and the straw is broken in the form of chaff. Threshed grains, chaff and other foreign matters pass through the concave openings and fall on the oscillating sieve assembly. The aspirators suck and blow out the chaff and lighter impurities through outlet. Cleaning sieves further separate the heavy straw, bigger impurities, clean grain, broken grain through oscillating motion of sieve assembly. T he secondary in let of blower does final cleaning and clean grain is obtained at the main grain outlet.
