[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A rice processing device for removing impurities and stones, such as Figures 1-4 As shown, the device includes a placement cylinder 1, on which several electric push rods 2 are fixedly connected. A connecting plate 3 is fixedly connected to the telescopic end of each electric push rod 2, and a connecting rod 4 is fixedly connected to the connecting plate 3. A positioning ring 5 is slidably connected inside the placement cylinder 1, and a filter screen 6 is fixedly connected to the positioning ring 5. A through groove 7 is provided on the placement cylinder 1, and a sealing assembly for sealing the through groove 7 is provided. The placement cylinder 1 also has a debris removal mechanism for removing gravel. When descrambling is required, water can be added to the placement cylinder 1 first, followed by glucose, to adjust the water density to 1.5 g / cm³-2.0 g / cm³. At this point, the density of water is greater than the density of rice and less than the density of grains. Based on the density of the pebbles, rice is then placed into the placement cylinder 1. The rice floats while the pebbles sink to the bottom. Next, the electric push rod 2 is activated to retract, which, through the connecting plate 3 and connecting rod 4, drives the positioning ring 5 and filter screen 6 to gradually approach the rice in the placement cylinder 1. Subsequently, the filter screen 6 comes into contact with the rice and presses the rice into the water, causing it to vibrate. This allows the pebbles in the rice to be separated from the rice more quickly and sink to the bottom. Then, the impurity removal mechanism is activated. The impurity removal mechanism comes into contact with the sealing component, preventing the sealing component from blocking the passage 7. At this time, the impurity removal mechanism can push the pebbles that have sunk to the side of the sealing component and remove the pebbles. This prevents the rice from being mixed with pebbles, which would affect the overall quality of the rice.

[0021] like Figures 1-3 As shown, the sealing assembly includes a sealing block 8 slidably connected within the through groove 7 and several spring telescopic rods 9 fixedly connected to the placement cylinder 1. The telescopic ends of the spring telescopic rods 9 are all fixedly connected to the sealing block 8. When the spring telescopic rods 9 are in the normal state, the sealing block 8 is in the through groove 7. When the sealing block 8 is pushed by the impurity removal mechanism, the spring telescopic rods 9 will become stretched. At this time, the sealing block 8 no longer seals the through groove 7, and the impurity removal mechanism will push the gravel out from one side of the sealing block 8 for removal. Then the impurity removal mechanism resets, the spring telescopic rods 9 also reset, and drive the sealing block 8 to seal the through groove 7 again, thereby preventing water from flowing out of the placement frame cylinder, thus saving resources and reducing costs.

[0022] like Figures 1-4As shown, the impurity removal mechanism includes a push plate 10 slidably connected in the through groove 7 and an electric push rod 11 fixedly connected to the placement cylinder 1. The telescopic end of the electric push rod 11 is fixedly connected to the push plate 10. The push plate 10 is provided with a removal component for easy removal of rice. The push plate 10 has a groove 12. The removal component includes a positioning ring 13 detachably connected in the groove 12, a filter screen 14 fixedly connected to the positioning ring 13, and a magnetic ring 15 fixedly connected to the upper side of the positioning ring 13. The positioning ring 15 is provided with an adsorption component for lifting the positioning ring 13. The adsorption component includes several positioning rods 16 fixedly connected to the lower side of the positioning ring 13 and a magnet 17 fixedly connected to the other end of the positioning rods 16. The magnet 17 and the magnetic ring 15 attract each other.

[0023] like Figures 1-4 As shown, when the gravel settles to the bottom, the electric push rod 11 can be activated. The electric push rod 11 will then retract rapidly, causing the push plate 10 to approach the sealing block 8, preventing water from flowing out between the groove 12 and the through groove 7. At this time, the gravel that has settled to the bottom will also be pushed by the push plate 10 towards the sealing block 8. Subsequently, the push plate 10 will push the sealing block 8 so that the sealing block 8 is no longer in contact with the placement cylinder 1. At this time, the gravel that has settled to the bottom will also be pushed out of the placement cylinder 1 by the push plate 10, thus completing the gravel cleaning.

[0024] like Figures 1-4 As shown, when it is necessary to remove the rice, the electric push rod 11 can be extended, and the spring telescopic rod 9 will drive the sealing block 8 to reset. When the spring telescopic rod 9 is in the normal state and the push plate 10 is in contact with the sealing block 8, the electric push rod 2 can be retracted to drive the positioning ring 5 to descend, so that the magnet 17 approaches the magnetic ring 15 and attracts the magnetic ring 15. Then the electric push rod 2 can be extended to drive the positioning ring 5 and the positioning ring 13 to rise. At this time, the rice will be supported by the positioning ring 13 and the filter screen 14 and moved away from the water surface. When the positioning ring 13 is away from the placement cylinder 1, the magnet 17 can be separated from the magnetic ring 15, and the positioning ring 13 can be removed separately. This makes it easier to remove the rice from the placement cylinder 1. Then the electric push rod 11 quickly extends and resets to seal the other end of the through groove 7 to prevent water from flowing out between the groove 12 and the through groove 7. Finally, the positioning ring 13 is put back into the groove 12 to remove impurities and stones again.

[0025] like Figure 4 As shown, a limiting block 18 is fixedly connected inside the groove 12. The positioning ring 13 is provided with an insertion groove 19 for the limiting block 18 to be inserted. When the positioning ring 13 is placed into the groove 12, the insertion groove 19 must be aligned with the limiting block 18 before insertion. If the positioning ring 13 is not aligned, it will vibrate. This is to confirm the orientation of the positioning ring 13 and prevent the magnetic ring 15 from facing down.

[0026] Working principle: When descaling is required, first add water to the placement cylinder 1, then add glucose to adjust the water density to 1.5g / cm³-2.0g / cm³. Next, add rice to the placement cylinder 1. Then, activate the electric push rod 2 to retract, which, through the connecting plate 3 and connecting rod 4, drives the positioning ring 5 and filter screen 6 to gradually approach the rice in the placement cylinder 1. The filter screen 6 then contacts the rice, pressing it into the water and causing it to vibrate, thus further removing the stones from the rice. The gravel is quickly separated from the rice and sinks to the bottom. Then, the electric push rod 11 is activated. The electric push rod 11 will then retract quickly, moving the push plate 10 closer to the sealing block 8 to prevent water from flowing out between the groove 12 and the through groove 7. At this time, the gravel that has sunk to the bottom will also be pushed by the push plate 10 towards the sealing block 8. Then, the push plate 10 will push the sealing block 8 so that the sealing block 8 is no longer in contact with the placement cylinder 1. At this time, the gravel that has sunk to the bottom will also be pushed out of the placement cylinder 1 by the push plate 10, thus completing the gravel cleaning.

[0027] When it is necessary to remove the rice, the electric push rod 11 can be extended, and the spring telescopic rod 9 will drive the sealing block 8 to reset. When the spring telescopic rod 9 is in the normal state and the push plate 10 is in contact with the sealing block 8, the electric push rod 2 can be retracted to drive the positioning ring 5 to descend, so that the magnet 17 approaches the magnetic ring 15 and attracts the magnetic ring 15. Then the electric push rod 2 can be extended to drive the positioning ring 5 and the positioning ring 13 to rise. At this time, the rice will be supported by the positioning ring 13 and the filter screen 14 and moved away from the water surface. After the positioning ring 13 moves away from the placement cylinder 1, the magnet 17 can be separated from the magnetic ring 15, and the positioning ring 13 can be removed separately. In this way, the rice can be taken out of the placement cylinder 1 more easily.
