For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0024] Example 1: Reference Figure 1-4The rice grading and sorting device shown includes a frame 1, inside which multiple screening components are arranged from top to bottom. Each screening component includes a pair of filter plates 13 fixedly connected to the inner wall of the frame 1. The pair of filter plates 13 are symmetrically arranged, with one end of each filter plate 13 being arc-shaped. The diameter of the filter holes in the filter plates 13 decreases sequentially from top to bottom. Multiple discharge ports 9, adapted to the filter plates 13, are opened on the outer side of the frame 1. A deflecting rod 6 passes through the outer side of the frame 1. One end of the deflecting rod 6 is equipped with a cleaning component, facilitating multi-stage filtration of the rice and reciprocating cleaning of the filter plates 13, reducing clogging. The cleaning component includes a reciprocating screw 11 fixedly connected to one end of the deflecting rod 6. A sliding block 12 is threaded onto the outer side of rod 11. A sliding rod 18 is fixedly connected to the bottom of sliding block 12. The sliding rod 18 slides between a pair of filter plates 13 at the same height. Sliding plates 16 adapted to filter plates 13 are fixedly connected to both sides of sliding rod 18. Protrusions 17 adapted to filter plates 13 are fixedly connected to the outer side of sliding plates 16. Protrusions 17 are made of rubber blocks. Through the deformability of protrusions 17, the filter holes are cleaned by the squeezing of protrusions 17 by filter plates 13 and the reciprocating deformation of protrusions 17. Multiple rotating rods 5 are threaded through the outer side of frame 1. Multiple stirring plates 14 are fixedly connected to the outer side of rotating rods 5. Push plates 15 adapted to filter plates 13 are fixedly connected to the outer side of rotating rods 5. The filtered rice is pushed out of the discharge port 9 by the push plates 15.
[0025] In this embodiment, rice is introduced through two input pipes 8. The rice of different sizes is graded and filtered by multiple filter plates 13 with progressively smaller filter hole diameters from top to bottom. During the rotation of one of the rotating rods 5, the deflection rod 6 and the reciprocating screw 11 are driven to rotate through the connecting track 7. The sliding block 12 drives the sliding rod 18, the sliding plate 16, and the protrusion 17 to move. The filter plate 13 squeezes the protrusion 17, causing the protrusion 17 to deform. During the movement, the protrusion 17 cooperates with the filter hole, restores its shape, and pushes the rice out of the filter hole, realizing the reciprocating cleaning of the filter plate 13 and reducing the clogging of the filter plate 13.
[0026] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a pair of fixed frames 3 are fixedly connected to the outer side of the frame 1, and a motor 4 is fixedly connected to the inner wall of the fixed frame 3. The output end of the motor 4 is fixedly connected to the corresponding rotating rod 5, and the fixed frame 3 supports the motor 4. A top cover 2 is provided at the top of the frame 1, and a connected input pipe 8 is fixedly connected to both sides of the frame 1. A groove 19 is provided on the outer side of both the deflection rod 6 and one of the rotating rods 5. A connecting track 7 is provided in the two grooves 19. A first recessed groove 20 is provided on the outer side of the rotating rod 5, and a second recessed groove 22 is provided on the outer side of the rotating rod 5. The same first transmission track 21 is provided in the two first recessed grooves 20 in the same column, and the same second transmission track 23 is provided in the two second recessed grooves 22 in the same column. A collection frame 10 is slidably connected to the bottom of the inner wall of the frame 1, and an empty groove adapted to the collection frame 10 is provided on the outer side of the frame 1.
[0027] In this embodiment, the control motor 4 drives the corresponding rotating rod 5 to rotate. Through the cooperation of the corresponding first transmission track 21 and second transmission track 23, multiple rotating rods 5 drive the corresponding stirring plate 14 and push plate 15 to rotate. The rotating rod 5 drives the stirring plate 14 to rotate and stir the rice piled at the bottom of the filter plate 13, thus accelerating the filtration of the rice. The push plate 15 pushes the filtered rice out of the discharge port 9. The smallest rice falls into the collection frame 10. The collection frame 10 is dragged to pull it out, thus collecting the smallest rice.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
