[0002] Rice is the seed of an annual herbaceous plant belonging to the genus Oryza of the Poaceae family. It is one of the most important food crops for humankind. It consists of a husk (outer shell) and a caryopsis (brown rice). After the husk is removed, it becomes rice. Rice can be classified into indica rice, japonica rice, and glutinous rice according to grain shape and texture, and into early rice, mid-season rice, and late rice according to its growth period. It is rich in nutrients such as carbohydrates, proteins, and B vitamins. After processing, it can be made into rice, rice noodles, and other foods. It is also a raw material for industries such as brewing and sugar refining, and occupies a key position in global food security.

[0003] In rice crushing and screening equipment, the screen plates are mostly fixed structures. After long-term use, the screen holes are easily clogged by rice fragments and fine impurities, resulting in a decrease in screening efficiency. Cleaning the clogged screen holes requires disassembling the equipment, which is a complicated and cumbersome process. Therefore, it is necessary to design a rice crushing and screening equipment. The screen plate is fixed by the cooperation of the buckle and the slot. No tools are required for disassembly. The screen plate can be removed manually to clean the screen hole blockage. During installation, simply align the buckle and press it to complete the process. The operation is convenient, saves time, and ensures that the screen plate is stable and does not shake during the screening process. Utility Model Content

[0022] In the following description, embodiments of the rice crushing and cleaning equipment of this utility model will be described with reference to the accompanying drawings.

[0023] Figure 1-4This invention illustrates a rice crushing and cleaning device according to an embodiment of the present invention. It includes a frame 1, a vibrating motor 2 installed at the bottom of the inner cavity of the frame 1, a screen box 3 disposed within the inner cavity of the frame 1, the vibrating motor 2 fixedly connected to the bottom of the screen box 3, a rice strainer 5 fixedly installed at the central axis of the inner cavity of the screen box 3, two symmetrical grading screens 6 slidably connected to the upper and lower parts of the inner cavity of the rice strainer 5, a feed hopper 4 fixedly connected to the rear side of the top of the frame 1, the discharge port of the feed hopper 4 communicating with the upper grading screens 6, a discharge port 7 connected to the right end of the rice strainer 5, and a connecting block 9 disposed above the central axis of the front side of the screen box 3, located above the upper grading screens. A fixing plate 8 is fixedly connected to the front side of screen 6 by two bolts. The fixing plate 8 is fixedly connected to the connecting block 9. Through the cooperation of the fixing plate 8 and the mounting plate 10, the fixing plate 8 and the mounting plate 10 provide a stable installation foundation for the connecting block 9 and the mounting block 11, respectively, so that the connecting block 9 and the mounting block 11 are stable in position during equipment operation. The bolt fixing connection method of the fixing plate 8 and the mounting plate 10 ensures that the connecting block 9 and the mounting block 11 can be stably connected during the crushing and filtering operation. The mounting block 11 is set below the central axis on the front side of the screen box 3. The mounting plate 10 is fixedly connected to the front side of the lower grading screen 6 by two bolts. Plate 10 is fixedly connected to mounting block 11. Mounting base plate 12 is provided on the right side of connecting block 9 and mounting block 11. Mounting base plate 12 is fixedly connected to screen box 3 by bolts. A sliding groove 13 is fixedly connected to the front side of mounting base plate 12. A sliding rod 14 is slidably connected to the inner cavity of sliding groove 13. A connecting rod 15 is fixedly connected to the surface of sliding rod 14. The upper grading screen 6 filters gravel larger than rice grains, while the lower grading screen 6 filters gravel smaller than rice grains. A fork-shaped component 16 is fixedly connected to the left side of sliding rod 14. The fork-shaped component 16 penetrates into the inner cavity of connecting block 9 and mounting block 11 and slides with connecting block 9 and mounting block 11. The mounting base 12 is fixedly connected to the front side of an inner circular groove 17. A bolt 18 is installed through the inner cavity of the inner circular groove 17. A nut is threaded onto the surface of the bolt 18. The bolt 18 fits tightly against the right side of the slide rod 14. The inner circular groove 17 guides the bolt 18. When the bolt 18 is locked to the slide rod 14, it will not move within the inner cavity of the inner circular groove 17 when the nut is tightened. When the bolt 18 is released from the slide rod 14 and the nut is loosened, the bolt 18 can rotate within the inner cavity of the inner circular groove 17, ensuring the stability of the bolt 18's positioning of the slide rod 14.

[0024] Working principle: When using this utility model, first place the two grading screens 6 into the screen box 3, ensuring they are placed stably. Then, use the connecting rod 15 to push the sliding rod 14, allowing it to slide within the inner cavity of the sliding groove 13. As the sliding rod 14 moves, it will cause the fork-shaped piece 16 on the left side to align with the inner cavity of the connecting block 9 and the mounting block 11 and insert it into place. Next, rotate the nut on the surface of the bolt 18 to loosen it, and push the bolt 18 to move it within the circular groove 17 of the block until it tightly abuts against one end of the sliding rod 14. Then, rotate the nut to fix the bolt 18. In this way, the two... The grading screen 6 is stably installed inside the screen box 3 and will not slip or fall off. When the vibration motor 2 is turned on, the vibration generated by the motor is transmitted through the screen box 3 to the grading screen 6 and the rice strainer 5, forming a continuous screening power. When discharging, the rice enters the upper grading screen 6 from the feed hopper 4. Under the action of vibration, the gravel larger than the rice is intercepted. The rice and small gravel pass through the screen holes and fall into the lower grading screen 6 through the rice strainer 5. After the small gravel is filtered by the lower screen, the clean rice slides to the right end through the rice strainer 5 and is finally discharged from the discharge port 7, completing the cleaning operation.

[0025] In summary, this rice crushing and stone cleaning equipment places two grading screens 6 into the inner cavity of the screen box 3. Through the cooperation of the connecting block 9, the mounting block 11, and the sliding rod 14, the two grading screens 6 are installed in the inner cavity of the screen box 3. Rice is poured into the inner cavity of the feed hopper 4. Stones larger than rice fall into the inner cavity of the upper grading screen 6, and stones smaller than rice fall into the inner cavity of the lower grading screen 6. Finally, the clean rice passes through the rice strainer 5 and flows out from the discharge port 7. This achieves the purpose of the screen plate adopting a snap-fit ​​fixing structure, which can be quickly disassembled and assembled without tools, can clean the screen hole blockage, save maintenance time, and ensure that the screen plate is stable and does not shake during the screening process.
