This Euro-base Multi-function thresher consists of a feeder hopper, a drum, a screen and a shelf. It integrates threshing, separating, straw chopping as a whole and can be used for wheat, rapeseed, corn, sorghum, soybean, rice and millet. When the multi-thresher machine is working, the crops are fed continuously and evenly. The crop is separated from the stalk by friction, extrusion, collision and shaking between the rack on the drum and the screen after the grain is separated from the stalk and the stalk is blown out by the draught fan. Meanwhile, the kernels come out from another cabinet.
