The discharging mechanism 8 includes a driving gear ring 81 fixedly mounted on the outer side of the discharging plate 7. The interior of the screening frame 5 is rotatably connected to a plurality of active rods 82 and transition rods 83. Both ends of the active rod 82 are fixedly mounted with active gears 84.

When the discharge plate 7 at the interval position needs to be rotated to make its upper opening relative to the opening at the position or staggered during the cycle switching, the sieving frame 5 can be rotated inside the drive box 4, and the reciprocating gear 872 is driven by the electric telescopic rod 871 to mesh with the inner gear ring 874 on the reciprocating ring 873, so that the sieving frame 5 can drive the screw 87 to rotate when it rotates. When the screw 87 rotates, the displacement rod 88 thereon can slide inside the sifting frame 5, so that the intermittent rack 89 on the displacement rod 88 rotates the active gear 84 on the active rod 82 at the separated position, and then through the action of the bevel gear 86, the transition gears 85 on the two transition rods 83 can rotate at the same time, and then through the action of one of the transition gears 85 and the driving gear ring 81 on the discharge plate 7, the discharge plate 7 at the separated position can be rotated to transport the rice at the separated position inside the sifting frame 5 to the next level. When the displacement rod 88 moves to the bottom end of the sifting frame 5, the reciprocating gear 872 can be driven by the electric telescopic rod 871 to mesh with the inner gear ring 874, so that the screw 87 rotates in the opposite direction, and then reaches the position The reciprocating sliding action of the shift rod 88 inside the sifting frame 5 allows the discharging plate 7 at the interval position to rotate, and the rice is transported to the next level of screening.

The sifting frame 5 as a whole can be driven by the driving motor 42 to drive the driving rod 6 to rotate, and then the driving rod 6 drives the sifting frame 5 to rotate, so as to further improve the rice screening efficiency of the equipment.

[0028] In the present embodiment, when in use, first, the sifting frame 5 is rotated on the driving box 4 and the supporting frame 2, so that the sifting frame 5 drives the rotating ring 92 to rotate inside the driving box 4, and the rice to be screened inside the storage chamber 93 is transported to the inside of the sifting frame 5 through the conveying pipe 91. After being screened by the first sieve ring 51 inside the sifting frame 5, the reciprocating gear 872 can be driven to mesh with the inner gear ring 874 through the electric telescopic rod 871, so that the sifting frame 5 drives the screw 87 to rotate synchronously when rotating, and the rotation of the screw 87 can make the displacement rod 88 on it slide outward inside the sifting frame 5, so that the active gear 84 at the interval position can be driven to rotate through the intermittent rack 89 on the displacement rod 88, and then the transition gear 85 is driven to rotate through the bevel gear 86, so that the interval position The discharging plate 7 can be driven to rotate by the driving gear ring 81 on it through the transition gear 85. The discharging plate 7 rotates until the opening on it corresponds to the opening at the position of the screening frame 5 to transport the rice to the second sieve ring 52 of the next level. The discharging plate 7 continues to rotate so that the openings can be staggered with each other to seal and close the position. When the displacement rod 88 needs to slide reversely inside the screening frame 5, the reciprocating gear 872 can be meshed with the outer gear ring 875, so that the discharging plates 7 at different positions can be reciprocated and closed at intervals, so that the rice inside the screening frame 5 can be intermittently screened by the first sieve ring 51, the second sieve ring 52, the third sieve ring 53 and the fourth sieve ring 54, thereby improving the screening effect of the overall equipment on rice residue and the screening work efficiency.
