The invention discloses a grain screening device capable of achieving rapid screening. The grain screening device comprises a shell. A work box is movably connected in the shell. The left side and theright side of the inner wall of the work box are fixedly connected with fixed blocks. A screening plate located at the tops of the fixed blocks is movably connected in the work box. The screening plate and the fixed blocks are in sliding connection. A supporting plate is fixedly connected to the back face of the inner wall of the shell. According to the grain screening device capable of achievingrapid screening, a transmission motor is arranged to drive an incomplete gear to rotate through a transmission rod, the incomplete gear drives a rectangular toothed plate to do left-and-right reciprocating motion, the rectangular toothed plate drives the work box to shake through a transmission block, and therefore grain is screened; the problems that in the traditional impurity removal process,the labor intensity of farmers is quite large, and the screening effect is poor are solved; and the grain screening device capable of achieving rapid screening has the advantages that the screening effect is good, and time and labor are saved.
Description
technical field [0001] The invention relates to the technical field of screening, in particular to a fast screening grain screening device. Background technique [0002] "Grain" covers a wide range, including rice, wheat, millet, soybeans, etc. and other miscellaneous grains. Cereals include rice, wheat, millet, soybeans, etc., mainly plant seeds and fruits, and are the traditional staple food of many Asian peoples. [0003] The grain coming out of the harvester often contains dust, wheat ears, wheat bran, shriveled particles, etc., so that the grain cannot be directly stored and used. Therefore, the harvested grain must be screened. In the traditional process of removing impurities, farmers They use the exhaust fan to blow away the impurities mixed in the grain, so that the grain is separated from the impurities, but this traditional method of impurity removal makes the labor intensity of farmers very high and cannot be continuously screened, so the screening efficiency is...
