The invention discloses grain screening agricultural equipment. The grain screening agricultural equipment comprises a drying assembly and a screening assembly. The drying assembly comprises a feedinghopper, a drying cylinder, a feeding pipeline, an air inlet pipeline, an air blower, an electric heating component, a temperature sensor, a stirring motor, a stirring shaft, stirring blades and a dust outlet pipeline. The bottom of the drying cylinder communicates with the screening assembly, a screen net pipeline of the screening assembly communicates with the drying cylinder, the bottom of thescreen net pipeline communicates with a screening pipeline, a collecting pipeline and an impurity pipe, and the screening pipeline and the impurity pipe are symmetrical vertically with respect to thescreen net pipeline. A screening fan is arranged at the end of the screening pipeline, the collecting pipeline is arranged between the screening pipeline and the impurity pipe, the bottom end of the collecting pipeline communicates with a collecting bin, the end of the impurity pipe communicates with an impurity box, and a screen net is further arranged inside the collecting pipeline. The grain screening agricultural equipment is higher in screening efficiency and integrates drying and screening.
