[0002] Rice is one of the main grain varieties in my country. my country has a high rice production, but the quality varies. Some rice grains are small and some are large, so it is necessary to separate rice grains of different grades for sale and consumption.

[0003] A rice grading and selection device, disclosed in CN221157666U, includes a box body. Multiple strip-shaped holes are evenly distributed on one side of the box body. Rectangular frames slide within each of the strip-shaped holes, with one end extending into the box body. The ends of the rectangular frames inside the box body are angled downwards. Filter screens are fixedly installed within the rectangular frames, with the mesh size of the filter screens increasing sequentially from top to bottom. A groove is formed at the upper end of each rectangular frame within the strip-shaped holes, and a locking mechanism is fixed within the groove. A feed pipe is fixedly connected to the upper end of the box body near the strip-shaped holes, and a discharge pipe is fixedly connected to the bottom of the box body. Discharge holes are formed on the side wall of the box body away from the strip-shaped holes, located on the upper side of the rectangular frames. This invention allows for easy replacement of filter screens with different mesh sizes as needed, offering strong versatility. However, in existing devices, during the sieving process, particles in the rice, similar in size to the filter screen meshes, easily clog the mesh. Prolonged sieving leads to significant mesh blockage, affecting the sieving effect and requiring disassembly and cleaning of the sieving screen, which is inconvenient and reduces sieving efficiency.

[0029] like Figure 1 and Figure 2As shown, specifically, the first screen 2 and the second screen 3 are both inclined in opposite directions, and a vibrator 13 is installed below both the first screen 2 and the second screen 3; since the first screen 2 and the second screen 3 are both inclined in opposite directions, it is convenient to collect the sieved rice, and the operation of the vibrator 13 can speed up the work efficiency.

[0030] like Figure 1 and Figure 2 As shown, specifically, the outer side of the selection box 1 is provided with an inspection door 14 and a control box 15; the inspection door 14 facilitates the maintenance of the internal components of the selection box 1, and the control box 15 facilitates the operation of the control device.

[0031] Working principle: The finished rice can be graded and screened through the first screen 2 and the second screen 3. The drive motor 41 drives the lead screw 42 to rotate, which in turn drives the transmission block 43 and the pusher plate 44 to move. The pusher plate 44 pushes the screened rice above the first screen 2 and the second screen 3 to the first discharge port 8 and the second discharge port 9 for collection. The pusher plate 44 drives the brush plate 45 to move, which can clean the clogged mesh on the first screen 2 and the second screen 3. The screens can be automatically cleaned, eliminating the need for frequent manual cleaning and reducing the labor intensity and speeding up the work.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
