Agricultural mechanical equipment for screening excellent seeds in agricultural planting

The invention discloses agricultural mechanical equipment for screening excellent seeds in agricultural planting, which comprises a supporting seat, a rotating motor is arranged in the supporting seat, a roller is arranged on the front side of the supporting seat, the roller is connected to the rotating motor, a seed storage box is arranged on the roller, a plurality of rows of mounting holes are formed in the peripheral side of the roller, and annular weighing sensors are mounted in the mounting holes. The lower end of the annular weighing sensor communicates with a hose, the hose communicates with an air pump, an electromagnetic valve is arranged on the hose, and a control panel is arranged on the front side of the roller. And two material receiving barrels are arranged below the roller. The rotary drum is driven by the rotating motor to rotate, seeds in the seed storage box are adsorbed to the annular weighing sensor through the air pump, when the seeds rotate to the highest point, the annular weighing sen
