The feeding box 6 is fixedly connected to the screening box 4 and communicates with the screening box 4. The conical plate 7 is arranged inside the screening box 4. A groove matching the conical plate 7 is formed on the screening plate 5. The driving component is arranged on the screening box 4 for driving the screening plate 5 to rotate. The driving component includes: a rotating rod 8, a rotating gear 9, a driving gear 10, and a first motor 11. A stabilizing frame 23 is fixedly connected to the screening box 4.

When the rotating gear 9 rotates, it drives the rotating rod 8 and the screening plate 5 to rotate, thereby stirring the peanuts inside the screening box 4. While stirring, the impurities mixed in the peanuts are discharged through the screening holes into the discharge box 3.

[0056] As Figures 1 to 3 shown, a cleaning mechanism is arranged on the screening box 4 for discharging impurities.

The output end of the third motor 22 penetrates through the conveying plate 19 and is fixedly connected to one of the conveying shafts 20. Specifically, the third motor 22 arranged on the conveying plate 19 drives the conveying shaft 20 and the conveyor belt 21 to rotate. When the conveyor belt 21 rotates, it conveys the peanuts.

[0059] In this embodiment, when screening impurities in peanuts, the peanuts with impurities are poured into the feeding box 6. The peanuts enter the screening box 4 through the feeding box 6. Then, the first motor 11 is started. The first motor 11 drives the driving gear 10 and the rotating gear 9 to rotate. When the rotating gear 9 rotates, it drives the rotating rod 8 and the screening plate 5 to rotate, so as to stir the peanuts in the screening box 4. While stirring, the impurities mixed in the peanuts are discharged through the screening holes into the discharge box 3. Then, the second motor 15 is started to drive the power gear 14 and the toothed ring 12 to rotate. When the toothed ring 12 rotates, it drives the two connecting blocks 24 and the discharge paddle 13 to rotate in the discharge box 3, so as to dial out the impurities collected in the discharge box 3. After the peanuts are screened, the first electric cylinder 18 is started to drive the fixing frame 17 and the blanking plate 16 to descend. When the blanking plate 16 descends, it drives the conical plate 7 arranged on the blanking plate 16 away from the screening box 4, so that the screened peanuts fall onto the conveyor belt 21 for discharging. Then, the third motor 22 is started to drive the conveying shaft 20 and the conveyor belt 21 to rotate. When the conveyor belt 21 rotates, it conveys the peanuts.
