The present invention relates to a grain thresher. Semi-circular guide rails to which a thrashing mesh is inwardly fitted are respectively spot welded on both sides of side plates positioned on an inward portion of a container in a main body to be opposite to each other. A long recess portion inside a front inlet and a bent frame inside a rear chaff outlet are fixed by bolts inserted at constant intervals. The thrashing mesh having a plurality of through holes is pushed in to be inwardly fitted to the semi-circular guide rails and the long recess portion. Bolt holes provided on a rear bent portion are fitted to the bolts fixed to corresponding positions and fixed by nuts. A thrashing mesh having through holes suiting grain such as millet, sorghum, millet, and bean is provided to be selectively replaced by attachment and detachment. Opening and shutting doors are fitted to guide supports on both sides of a ventilator to adjust an air flow rate according to the weight of grain to be threshed. Accordingly, provided is a versatile thresher capable of efficiently threshing grains different in size, shape, and weight while reducing the number of workers in the farmhouse with one thresher. |
