Premix particle screening device capable of improving screening speed and used for poultry

The premixing agent particle screening device comprises a base, universal wheels are fixedly installed at the four corners of the bottom of the base, a driving motor is fixedly installed at the bottom of the base, and an output shaft of the driving motor penetrates through the base and extends to the position above the base. An output shaft of the driving motor is fixedly sleeved with a hollow large gear, two connecting rods are rotationally connected to the output shaft of the driving motor, the ends, away from each other, of the two connecting rods are fixedly connected with supporting rods, the two supporting rods are in transmission connection with the large gear, and the tops of the two supporting rods are fixedly connected with the same swing plate; according to the premixing agent screening device, screening of premixing agents is achieved through transmission between the driving motor and the screen, the screening speed is high, the screening effect is good, screening time is saved, efficiency is impr
