The flexible driving wheel is a rubber gear, and the rear end of the vibration plate extends into the tooth groove of the rubber gear. When the rubber gear rotates, the tooth surface of the wheel pushes the vibration plate to move in turn, making the vibration plate vibrate. At the same time, the rubber material has certain elasticity and will not rub Damage to the vibrating plate and gear tooth surface, reliable performance and long service life.

The power mechanism is a stepless speed regulating motor; the stepless speed regulating motor synchronously drives the impeller fan and the rubber wheel to prevent the soybean material from falling when the impeller fan is not started, and can adjust the wind force, and control the vibration and feeding frequency of the vibrating plate according to the wind force. Speed, automatic separation of impurities in soybean samples.

There are round handles which can be pulled out and pushed into the material collector and the miscellaneous container in the middle of the outer end faces of the material collector and miscellaneous container respectively, and the extraction and pushing are quick and stable.

In the wind separator for small soybean impurities in the utility model, the soybean material is transported from the hopper to the vibrating plate along the inner material guide plate of the feeding port, and the vibration plate is driven by the flexible driving wheel to vibrate and drop the material, and the impeller fan rotates and blasts to separate the inclusions in the soybean material. The impurities, soybeans fall into the collector, and the impurities are blown into the collector. The arc-shaped guide plate and the arc-shaped rear side wall provide wind guidance. Into the feeder, the stepless speed regulation motor synchronously drives the impeller fan and the rubber wheel to prevent the soybean material from falling when the impeller fan is not started, and can adjust the wind force, and control the frequency and speed of the vibrating plate vibration and feeding according to the wind force, which can automatically Separation of impurities in small soybean samples, compact structure, small size, light weight, easy operation, time-saving and labor-saving, and improved detection efficiency.
