VERTICAL AXIAL-FLOW THRESHING MACHINE

The utility model relates to a vertical type axial-flow threshing machine which is used for the threshing, the separating, the wind separating and the filtrating of the rice and wheat. The utility model is composed of an outer shell, a machine frame, a cylinder, fans, an escape grid, wind selecting panels with annular openings, a grain scraping speed reduction mechanism, an eccentric wheel four connecting rods transmission mechanism and a vibration sieve. Because the wind selecting panels with annular openings which are used as the outlet of the glume mixture are arranged on the upper part of the escape grid and the bottom of the fans, which make the wind selecting of the separated object have a long time, big space and a thorough wind selecting; because an eccentric wheel four connecting rods transmission mechanism is arranged on the grain scraping speed reduction mechanism, and drives the vibration sieve filtrating, so the cleanliness of the threshing is exceed 99%. The utility model has the advantages of safe using and light weight.
