The invention discloses a corn seed screening device for agricultural breeding. The corn seed screening device comprises a bottom plate. A left vertical plate and a right vertical plate are verticallyare fixedly installed on the bottom plate; a driven belt wheel is arranged and fixedly installed on a driven shaft in a sleeving mode; a driving belt wheel and the driven belt wheel are sleeved witha transmission belt; a screening basket movably penetrates between the left vertical plate and the right vertical plate in a mode of being inclined towards the lower-right portion; the upper end of aconnecting rod is hinged to the lower-left bottom face of the screening basket; and a first collecting groove is fixedly formed in the lower portion of the screening basket. A hot air machine conductshot air drying on corn seeds in a housing through an air supply pipe and an air collection cover; a driving shaft drives a spiral blade to turn over the corn seeds rotationally, so that hot air and the corn seeds can make full contact, and the drying effect is greatly improved; meanwhile, the corn seeds conveyed on a conveying belt are subjected to secondary air-blowing drying of fan blades and can be spread on the conveying belt, and thus the drying effect is better; and vibration of the screening basket to the corn seeds is facilitated through swinging of the screening basket, and thus thescreening rate is increased.
