Description

Technical Field

[0001] This utility model relates to the field of rice polishing technology, and in particular to a rice polishing machine that can reduce broken rice. Background Technology

[0002] Treating the surface of rice grains makes them crystal clear and forms a very thin gel film; this process is called polishing. The main function of a rice polishing machine is to remove bran and powder adhering to the surface of white rice. After polishing, the rice surface has a waxy protective layer, which not only prevents bran adhesion and powder shedding during production, storage, transportation, and sales, ensuring the cleanliness and hygiene of the rice, but also improves the quality and commercial value of the finished rice, facilitates storage, maintains freshness, and enhances its edible quality.

[0003] During the polishing process, excessively high rotation speed of the polishing wheel can cause a significant amount of broken rice. While reducing the rotation speed can decrease the amount of broken rice produced, even with timely speed reduction, a considerable amount of broken rice still remains. This broken rice mixed with premium rice negatively impacts its quality. Therefore, a rice polishing machine designed to reduce broken rice is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rice polishing machine that can reduce broken rice, thereby solving the aforementioned problems.

A side screening box is provided on one side of the rice polishing device. A polishing outlet is provided on the rice polishing device and located inside the side screening box. Multiple inclined triangular plates are rotatably mounted on the side wall of the side screening box. These inclined triangular plates are arranged symmetrically and alternately to facilitate the folding and sliding of rice. A screening and collecting assembly is provided on the inclined triangular plates. An adjusting rod is provided on the side screening box and connected to the inclined triangular plates. A vibrating screening assembly is provided on the top of the side screening box and connected to the adjusting rod.

[0006] Preferably, the screening and collecting assembly includes a triangular groove formed on the side of an inclined triangular plate, and a plurality of broken rice falling holes are formed on the inclined surface of the inclined triangular plate.

[0007] Preferably, a broken rice collection frame is placed inside the triangular groove, and a side enclosure is fixedly installed on the side of the inclined triangular plate.

[0008] Preferably, a plurality of transverse drag bars are fixedly installed on the inner wall of the side screening box, and a rubber pad is installed on the top of the transverse drag bar, with the top of the rubber pad contacting the bottom of the inclined triangular plate.

[0009] Preferably, the inclined triangular plate has an adjustment slot on its side, and an adjustment column is fixedly installed on the side of the adjustment rod, with one end of the adjustment column movably installed in the adjustment slot.

[0010] Preferably, the vibrating screening assembly includes a square frame fixedly installed on the top of the adjusting rod, a fixed rod fixedly installed on the top of the side screening box, a rotating motor fixedly installed on one side of the fixed rod, an elliptical drive wheel connected to the output end of the rotating motor, the elliptical drive wheel being adapted to the square frame, and multiple contact rollers rotatably installed on the top inner wall of the square frame, the multiple contact rollers being adapted to the elliptical drive wheel.

[0011] Preferably, the rice polishing equipment is provided with a polishing feed hopper at the top, a side operation hole is provided on one side of the side screening box, and a bottom collection box is placed at the bottom of the side screening box.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the rice polishing machine that can reduce broken rice is equipped with multiple inclined triangular plates. During the downward movement of polished rice, broken rice falls into the broken rice drop hole and is automatically screened. By setting multiple inclined triangular plates, broken rice can be effectively screened, ensuring the quality of polished rice. The vibrating screening component is designed so that as the rice falls, the rotating motor drives the elliptical wheel to rotate, which in turn moves the adjusting rod up and down. The inclined triangular plate can generate a certain amount of vibration, which can speed up the screening of rice on the inclined triangular plate and effectively avoid the problem of some broken rice getting stuck in the broken rice falling hole, thus speeding up the screening of broken rice.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Refer to Figure 1-4 A rice polishing machine that reduces broken rice includes a rice polishing device 1, a side screening box 3 on one side of the rice polishing device 1, a polishing outlet 4 on the rice polishing device 1 located inside the side screening box 3, multiple inclined triangular plates 6 rotatably mounted on the side wall of the side screening box 3, the multiple inclined triangular plates 6 being arranged alternately and symmetrically to facilitate the folding and sliding of rice, a screening and collection component on the inclined triangular plates 6, an adjusting rod 13 connected to the inclined triangular plates 6 on the side screening box 3, and a vibrating screen on the top of the side screening box 3. The components, the vibrating screening component and the adjusting rod 13 are connected. The top of the rice polishing equipment 1 is provided with a polishing feed hopper 2. The side of the side screening box 3 is provided with a side operation hole 5. The bottom of the side screening box 3 is provided with a bottom collection box 12. The rice to be polished is put into the polishing feed hopper 2 and enters the rice polishing equipment 1 for polishing. The polishing equipment 1 uses polishing rollers to achieve the polishing operation. During polishing, the speed of the polishing rollers is reduced to reduce the generation of broken rice. The polished rice will fall from the polishing discharge nozzle 4 and land on the uppermost inclined triangular plate 6.

[0017] Furthermore, the screening and collecting component includes a triangular groove 7 formed on the side of the inclined triangular plate 6. Multiple broken rice falling holes 8 are formed on the inclined surface of the inclined triangular plate 6. A broken rice collecting frame 9 is placed in the triangular groove 7. A side enclosure 10 is fixedly installed on the side of the inclined triangular plate 6. The broken rice falling holes 8 are provided on the inclined triangular plate 6. During the process of the polished rice sliding down at an incline, the broken rice will be automatically screened and fall into the broken rice collecting frame 9. Multiple inclined triangular plates 6 are provided, and the rice will pass through them in sequence, forming a folded falling.

[0018] Furthermore, multiple transverse drag bars 11 are fixedly installed on the inner wall of the side screening box 3. Rubber pads are installed on the top of the transverse drag bars 11, and the top of the rubber pads contacts the bottom of the inclined triangular plate 6. An adjustment slot 14 is opened on the side of the inclined triangular plate 6. An adjustment column 15 is fixedly installed on the side of the adjustment rod 13, and one end of the adjustment column 15 is movably installed in the adjustment slot 14. The vibrating screening assembly includes a square frame 16 fixedly installed on the top of the adjustment rod 13. A fixed rod 17 is fixedly installed on the top of the side screening box 3. A rotating motor 18 is fixedly installed on one side of the fixed rod 17. The output end of the rotating motor 18 is connected to an elliptical drive wheel 19, which is adapted to the square frame 16. Multiple contact rollers 20 are rotatably installed on the inner wall of the top side of the square frame 16, and these contact rollers 20 are adapted to the elliptical drive wheel 19. The rice, during its fall... During the process, the rotating motor 18 is started and runs, driving the elliptical drive wheel 19 to rotate. After the elliptical drive wheel 19 rotates, it will drive the square frame 16 to move upward, thereby driving the adjusting rod 13 to move upward. The multiple contact rollers 20 are set to reduce the contact friction between the elliptical drive wheel 19 and the square frame 16 during the rotation process. After the adjusting rod 13 moves upward, under the action of the adjusting column 15 and the adjusting groove 14, it can drive the inclined triangle plate 6 to swing to a certain extent. When the elliptical drive wheel 19 is misaligned with the square frame 16, it swings downward under the action of its own weight. The inclined triangle plate 6 achieves a certain swing amplitude. When the inclined triangle plate 6 falls on the horizontal drag bar 11, it can generate a certain vibration, which can accelerate the screening of rice on the inclined triangle plate 6 and effectively avoid the problem of some broken rice getting stuck in the broken rice drop hole 8, thus speeding up the screening of broken rice.

[0019] In use: During the rice production process, polishing is required. The polished rice will fall from the polishing outlet 4 and land on the uppermost inclined triangular plate 6 with broken rice drop holes 8. As the rice slides down at an incline, broken rice will be automatically sieved. There are multiple inclined triangular plates 6, and the rice will pass through them in sequence, forming a folded fall, which can effectively sieve broken rice. During the fall, the rotating motor 18 is started, which drives the elliptical drive wheel 19 to rotate, thereby driving the adjusting rod 13 to move upward. Under the action of the adjusting column 15 and the adjusting groove 14, the inclined triangular plate 6 can swing to a certain extent. After swinging upward, it will swing downward. When the inclined triangular plate 6 lands on the horizontal drag bar 11, it can generate a certain vibration, which can accelerate the sieving of rice on the inclined triangular plate 6 and effectively avoid the problem of some broken rice getting stuck in the broken rice drop holes 8, thus speeding up the sieving of broken rice and making it convenient to use.
