The invention discloses a coal screening and collecting method and device. The coal screening and collecting method comprises the steps that coal is fed; the screening assembly is used for screening the coal; and the transportation assembly quantitatively collects the coal. The coal screening device has the beneficial effects that the sorting unit, the conveying unit and the feeding unit are arranged, the driving assembly is started to drive the screening assembly to swing, coal is filtered and screened, the transmission assembly is driven to rotate, the conveying assembly is pushed to intermittently convey the coal, and it is guaranteed that the coal is conveyed into the overturning assembly after being evenly screened; when the weight of the coal is accumulated to be larger than the pulling force of the reset assembly, the coal is in contact with limiting of the reset assembly to be turned over, it is guaranteed that the coal with the same weight is poured in, after the coal is poured out, under pulling of
