Abstract
Description
Technical Field
[0001] The utility model relates to the field of crop processing, in particular to a parallel double-roller rice polishing machine. Background Art
[0002] In today's society, consumers have increasingly high expectations for rice quality. They focus not only on the taste and nutritional content of rice but also on its appearance. Rice with a bright, uniform appearance is more competitive in the market, so rice polishing machines are needed to polish rice to meet consumer demands for appearance and quality.
[0003] Traditional rice polishing machines lack effective control mechanisms during the feeding process, resulting in excessive accumulation of rice on the polishing rollers. This not only affects polishing uniformity, causing some rice to be over-polished and others to be under-polished, resulting in uneven overall rice quality and failing to meet market demand for high-quality rice, but also increases the load on the polishing rollers, increasing energy consumption and shortening the equipment's lifespan. This also increases maintenance costs and downtime, causing significant inconvenience and financial losses. After polishing, existing devices also fail to properly discharge the polished rice and rice bran, potentially preventing them from exiting the device smoothly and causing internal blockages. Once a blockage occurs, production is interrupted, reducing efficiency, and cleaning and repairs require significant manpower and time, increasing production costs.
[0004] Therefore, it is necessary to provide a kind of parallel double-roller rice polishing machine to solve the above-mentioned technical problems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and implementation examples.
[0021] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of a parallel double-roller rice polishing machine provided by the utility model; Figure 2 for Figure 1 A schematic back view of a parallel double-roller rice polishing machine is shown; Figure 3 for Figure 1 A schematic cross-sectional view of a parallel double-roller rice polishing machine is shown; Figure 4 for Figure 1 The structural diagram of the blanking roller shown; Figure 5 for Figure 3An enlarged schematic diagram of section A is shown. A parallel double-roller rice polisher comprises: a polishing chamber 1, wherein two polishing rods 2 are rotatably connected within the polishing chamber 1, and the two polishing rods 2 are fixedly connected to gears 3. One of the polishing rods 2 is fixedly connected to a motor 4, and the other polishing rod 2 is fixedly connected to a pulley 5. A belt 6 is connected to the pulley 5, and a pulley 7 is connected to the belt 6. A feed roller 8 is fixedly connected to the pulley 7. A feed bin 9 is fixedly connected to the top of the polishing chamber 1, and a raw material bin 10 is fixedly connected to the top of the feed bin 9. A feed separator 11 is fixedly connected to the feed roller 8, an anti-accumulation block 12 is fixedly connected to the feed roller 8, and a feed trough 13 is provided on the feed roller 8. A polishing roller 14 is fixedly connected to the surface of the polishing rod 2. This polishing machine ensures that the rice is not excessively accumulated on the polishing roller 14 during the polishing process, thereby ensuring that the rice is subjected to more uniform force during the polishing process. Each grain of rice is polished to perfection, avoiding over-polishing or under-polishing due to local accumulation, thereby significantly improving the surface smoothness and overall quality of the rice, making it more in line with the market standards for high-quality rice and enhancing the product's competitiveness in the market.
[0022] A central roller 15 is rotatably connected inside the polishing bin 1, and a lower rice trough 16 is fixedly connected to the central roller 15. A lower bran trough 17 is fixedly connected to the central roller 15. A discharge partition 18 is fixedly connected between the lower rice trough 16 and the lower bran trough 17. A lower bran opening 19 is opened on the left side of the polishing bin 1, and a lower rice opening 20 is opened on the right side of the polishing bin 1. The surface of the polishing roller 14 contacts the rice, and friction is generated during the rotation process, which causes bran powder and impurities on the surface of the rice to fall off, and at the same time makes the rice surface smoother. After unloading, the rice and rice bran are blown apart by the fan 26, and the rice falls on the lower rice trough 16, and the rice bran falls into the lower bran trough 17.
[0023] A second motor 21 is installed on the back of the polishing bin 1, and the output end of the second motor 21 is fixedly connected to a shaking disk 22, and a shaking rod 23 is fixedly connected to the shaking disk 22. A shaking plate 24 is fixedly connected to the lower rice trough 16, and a shaking groove 25 is provided on the shaking plate 24. When the second motor 21 is started, the second motor 21 drives the shaking disk 22 to rotate, and the shaking rod 23 on the shaking disk 22 drives the shaking plate 24 and then drives the lower rice trough 16 to shake, and can drive the lower bran trough 17 to shake through the central roller 15 to avoid blockage when the rice and rice bran are discharged.
[0024] A fan 26 is installed inside the polishing chamber 1, and an air inlet slot 27 is opened on the right side of the polishing chamber 1. The fan 26 uses the difference in specific gravity of rice and bran to blow away the bran by wind, while the rice falls due to its larger specific gravity, thereby achieving separation.
[0025] A guide groove 28 is provided on the front side of the polishing chamber 1 , and a guide rod 29 is slidably connected inside the guide groove 28 , and the guide rod 29 is fixedly connected to the lower rice trough 16 .
[0026] A polishing guide block 30 is fixedly connected inside the polishing bin 1 , a bracket 31 is fixedly connected to the surface of the polishing bin 1 , and a support rod 32 is fixedly connected to the bottom of the bracket 31 . The polishing guide block 30 can ensure that the rice enters the polishing area when unloading.
[0027] The working principle of a parallel double-roller rice polishing machine provided by the utility model is as follows:
[0028] Start motor 14, which drives the polishing rod 2 to rotate. The gears 3 on the two polishing rods 2 are engaged with each other, and the two polishing rollers 14 rotate relative to each other to polish the rice. At the same time, through the transmission connection of belt 6, the polishing rod 2 drives the discharge roller 8 to rotate. The discharge roller 8 is provided with staggered discharge troughs 13. When the discharge roller 8 rotates, the staggered discharge troughs 13 and the stacking-free blocks 12 can stagger the discharge of rice, thereby avoiding too much discharge onto the polishing roller 14 at one time, and avoiding over-polishing or insufficient polishing due to local accumulation.
[0029] Compared with the related art, the parallel double-roller rice polishing machine provided by the utility model has the following beneficial effects:
[0030] By ensuring that excessive rice accumulation on the polishing roller 14 is avoided during rice discharge, the polishing machine ensures that the rice is subjected to more uniform force during the polishing process. Each grain of rice is perfectly polished, avoiding over-polishing or under-polishing caused by local accumulation. This significantly improves the surface finish and overall quality of the rice, making it more in line with market standards for high-quality rice and enhancing the product's market competitiveness. Furthermore, the stable and appropriate discharge method, combined with the smooth discharge of polished rice and rice bran, effectively reduces equipment downtime caused by material accumulation or blockage.
