Buckwheat seed harvesting device for experimental field

The utility model relates to the technical field of buckwheat seed harvesting, and discloses a buckwheat seed harvesting device for an experimental field, which comprises a support frame, a hub fixedly mounted on the outer wall of the bottom of the support frame, a shell fixedly mounted on the outer wall of the top of the support frame, and a baffle fixedly mounted on the outer wall of the top of the shell. A motor drives a rotating shaft to rotate, the rotating rotating shaft can drive a plurality of separation wheels on the outer wall to rotate, the separation wheels with cross-shaped cross sections can separate and harvest plant seeds under the action of a square plate, and meanwhile a second limiting plate can limit the harvesting direction of each plant. According to the device for harvesting the plant seeds, the separation wheel is arranged, the phenomenon that the plant deviates when the separation wheel is used for harvesting is avoided, so that the phenomenon of missing harvesting of the harvested se
