Abstract
The utility model relates to a roller type grain classifying screen. The classifying screen comprises a roller screen, a support frame of a certain slope, a power mechanism, a feeding pipe arranged at one end of the roller screen, a collecting groove arranged at the other end of the roller screen, and a high frequency vibrator fixed on the support frame. A cylinder fitting the shape of the roller screen is sheathed and fixed outside the roller screen. A longitudinal central shaft is fixed in the center of the roller screen. The power mechanism is in soft connection with the central shaft by a coupler. A certain number of longitudinal screen nets are longitudinally and uniformly arranged on the inner side wall of the roller screen, and a certain number of horizontal screen nets are fixed between every two adjacent longitudinal screen nets. In addition, at least one grade roller type grain classifying screen sharing the same rotating shaft with the roller type grain classifying screen can also be fixed on the outer side or the inner side of the roller type grain classifying screen. The utility model can meet the strict requirement for classifying sizes. The match of the roller screen with the vibration mechanism can effectively prevent screen pores from being blocked. Multiple layers of rollers having the same rotating shaft simultaneously work, so the work efficiency is improved. The utility model is easy to popularize and use.
