[0002] Rice is a finished product made from paddy through cleaning, hulling, milling, and finishing processes. Rice contains nearly 64% of the nutrients found in paddy and more than 90% of the nutrients needed by the human body. It is also a staple food for people in most parts of China. Rice enters the spleen, stomach, and lung meridians and has the functions of replenishing qi, nourishing yin and moistening the lungs, strengthening the spleen and stomach, and relieving thirst. In order to ensure the quality of finished rice, make the grains whiter, brighter, and shinier, and improve the taste of rice;

[0003] Rice polishing is required during the production process, hence the use of rice polishing machines. However, traditional rice polishing equipment is not uniform enough, has a slow polishing efficiency, and is inconvenient to clean and disassemble the filter screen when filtering out broken rice and debris, resulting in poor filtration effect and affecting processing. Therefore, a rice polishing machine for rice processing is needed to improve the above problems. Utility Model Content

[0024] Example

[0025] Please see Figure 1 and Figure 2 A rice polishing machine for rice processing includes a working box 1, four bases 2 are symmetrically fixedly installed at the bottom of the working box 1, two feed holes are symmetrically opened on the working box 1, and a discharge pipe is connected to the outer wall of the working box 1, with a valve installed on the discharge pipe.

[0026] Please see Figure 1-3 The working box 1 is equipped with a polishing mechanism, which includes a motor 3. The motor 3 is fixedly installed on the working box 1. A rotating shaft 4 is fixedly installed at the output end of the motor 3. The rotating shaft 4 is rotatably connected to the working box 1. A conveying blade 5 is provided on the rotating shaft 4. A rotating plate 6 is fixedly installed on the rotating shaft 4. Multiple first polishing shafts 7 are fixedly installed on the inner side walls of both ends of the rotating plate 6. Two second polishing shafts 8 are symmetrically fixedly installed on the rotating plate 6. Multiple polishing points are provided on the multiple first polishing shafts 7 and the two second polishing shafts 8. A scraper 30 is fixedly installed at the bottom end of the rotating shaft 4. Rice is placed inside the working box 1. By starting the motor 3, the motor 3 provides power to drive the rotating shaft 4 to rotate, which in turn drives the conveying blades 5 and the rotating plate 6 to rotate. The rice is polished by the cooperation of the multiple first polishing shafts 7 and the two second polishing shafts 8. The rice is turned over by the conveying blades 5 to make the rice polished more evenly.

[0027] Please see Figure 1 , Figure 2 and Figure 4 The working box 1 is equipped with a filtration and collection mechanism, which includes a filter screen plate 9. A first sliding groove is formed on the working box 1, and the filter screen plate 9 is slidably connected to the first sliding groove. Second sliding grooves are formed at both ends of the first sliding groove. Two first sliders 10 are symmetrically fixedly installed on the filter screen plate 9, and the two first sliders 10 are slidably connected to the two second sliding grooves respectively. Second sliders 11 are fixedly installed on the filter screen plate 9. A third sliding groove is formed on the first sliding groove, and a top plate 12 is slidably installed in the third sliding groove. Multiple springs 13 are fixedly installed on the top plate 12. Each top plate 12 has another... Both ends are fixedly connected to the third slide groove. L-shaped plates 14 are fixedly installed on both first sliders 10. The two L-shaped plates 14 and the working box 1 are locked together by two bolts 15. A collection box 16 is slidably installed on the working box 1. The broken rice and debris generated during polishing fall into the collection box 16 through the filter screen 9 and are collected by the collection box 16. The surface of the filter screen 9 is cleaned and scraped by the scraper 30 to prevent debris from accumulating and clogging the filter holes. When the filter screen 9 needs to be replaced, the limiting operation of the filter screen 9 is released, and the filter screen 9 is pulled out for cleaning and replacement.

[0028] Please see Figure 1 and Figure 2 The work box 1 is equipped with multiple corner protectors 17, which protect the top corners of the work box 1 and protect the workers.

[0029] Please see Figure 1 An observation window 18 is provided on the work box 1, which facilitates timely observation of the internal condition of the work box 1.

[0030] Please see Figure 3 It should also be noted that a guide plate 19 is fixedly installed on the rotating plate 6. The guide plate 19 guides the rice and prevents it from piling up on the rotating plate 6.

[0031] Please see Figure 3 A stabilizing cylinder 20 is fixedly installed on the inner wall of the working box 1. The rotating shaft 4 is rotatably connected to the stabilizing cylinder 20. The stabilizing cylinder 20 makes the rotating shaft 4 more stable when it rotates.

[0032] Please see Figure 1 and Figure 2 Both feed holes are connected to feed hoppers 21, which facilitates the feeding of materials into the working box 1.

[0033] In summary, when using this rice polishing machine for rice processing, rice is placed inside the working box 1. The two feed hoppers 21 guide the rice during the process. The motor 3 is then started. This motor is a commercially available device known to those skilled in the art; we are only using it for practical application without making any structural or functional improvements, which we will not elaborate on here. The motor is equipped with a matching control switch, the installation position of which is selected according to actual practical needs for easy operation. The motor 3 provides power to drive the rotating shaft 4 to rotate, which in turn drives the conveyor blades 5 and the rotating plate 6 to rotate. Through the cooperation of multiple first polishing shafts 7 and two second polishing shafts 8, the rice is polished. The polishing process involves turning the rice over using conveyor blades 5 to ensure even polishing. Broken rice and debris from the polishing process are filtered through the filter screen 9 and fall into the collection box 16 for collection. The surface of the filter screen 9 is cleaned and scraped by scraper 30 to prevent debris buildup and clogging of the filter holes. When the filter screen 9 needs to be replaced, the two bolts 15 are rotated sequentially to release the locking mechanism on the two L-shaped plates 14. The spring force of multiple springs 13 causes the filter screen 9 to pop out, releasing its restraints. The filter screen 9 is then removed from the working box 1 for cleaning and replacement. Replacing the filter screen 9 improves filtration efficiency.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
