Wheat grading device for flour production and processing

The utility model relates to a wheat grading device for flour production and processing in the technical field of screening and grading equipment. The wheat grading device comprises a screening bin, a feeding bin, a rotating shaft, a first spiral auger, a second spiral auger, a reciprocating rotating assembly, a discharging bin and sieve plates, and the two sieve plates are driven by a vibration driving assembly to reciprocate up and down. The wheat can be classified and screened through the screening plates on the two discharging bins, in addition, through reciprocating rotation of the rotating shaft, the first spiral auger and the second spiral auger can convey the wheat put into the screening bin, the wheat is conveyed to the two sides in the axial direction of the screening bin, and then the wheat can be evenly conveyed to the two screening plates; in addition, due to the fact that the rotating shaft rotates in a reciprocating mode, the wheat can move in the screening bin in a reciprocating mode, the accu
