Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, and in particular to a cleaning device for rice processing. Background Technology

[0002] Rice is a finished product made from paddy rice through cleaning, hulling, milling, and finishing processes. The germ and aleurone layer of paddy rice contain nearly 64% of the rice's nutrients and over 90% of the nutrients needed by the human body. Rice contains approximately 75% carbohydrates, 7%-8% protein, 1.3%-1.8% fat, and is rich in B vitamins. The carbohydrates in rice are mainly starch, and the protein is primarily rice gluconate, followed by rice gluten and globulin. Its biological value and amino acid composition are higher than those of wheat, barley, millet, corn, and other cereal crops, making it one of the highest-protein cereal crops.

[0003] Rice contains a lot of rice husks, rice weevils, and impurities. These impurities float in the water during the washing process and need to be cleaned.

[0026] Reference Figure 1-5A rice processing cleaning device includes a cleaning tank 1. A vertical hole is formed in the side wall of the cleaning tank 1, and a transparent plate 2 is fixedly installed inside the vertical hole. A discharge port is formed in the side wall of the cleaning tank 1, and a sealing plate 7 is provided on the side wall of the cleaning tank 1 relative to the discharge port. A water outlet pipe 6 with a valve is connected to the bottom of the cleaning tank 1. A motor 16 is fixedly installed at the bottom of the cleaning tank 1, and a stirring shaft 12 is fixedly installed at the output shaft port of the motor 16. The stirring shaft 12 is rotatably inserted inside the cleaning tank 1. A fixing rod 13 is fixedly installed at the top of the stirring shaft 12. A cleaning mechanism for removing floating debris is provided on the surface of the fixing rod 13. The cleaning mechanism includes a screw 14 and a connecting block 20. The device has a slot, with the connecting block 20 engaging with the surface of the fixing rod 13. The screw 14 is threaded through the connecting block 20, engaging with the fixing rod 13. A collection box 15 is rotatably connected to the bottom end of the screw 14. A vertical groove 22 is provided on the side wall of the stirring shaft 12. A protrusion 21, matching the size of the vertical groove 22, is provided on the side wall of the collection box 15. The collection box 15 is slidably connected to the stirring shaft 12 via the protrusion. Therefore, rotating the screw 14 moves the screw 14 and the connecting block 20, causing the collection box 15 to move on the stirring shaft 12, thus adjusting the height of the collection box 15. A filter plate 11 is slidably connected inside the washing tank 1. During use, rice is poured into the washing tank 1 and then... Pour an appropriate amount of clean water into the cleaning tank 1. Install the cleaning mechanism on the fixed rod 13. The collection box 15 in the cleaning mechanism is fixedly installed at the bottom of the screw 14. The distance between the collection box 15 and the connecting block 20 can be changed by rotating the screw 14. Therefore, the distance between the collection box 15 and the connecting block 20 can be adjusted according to the water level in the cleaning tank 1. Finally, install the connecting block 20 on the fixed rod 13. After installation, the collection box 15 is positioned at the water level. Then, start the motor 16. The motor 16 drives the stirring shaft 12 to rotate. The stirring shaft 12 drives the fixed rod 13 to rotate. The fixed rod 13 drives the screw 14 and the collection box 15 in the cleaning mechanism to rotate synchronously. The collection box 15... When the rice rotates on the water surface, it can clean and collect the impurities floating on the water surface. After the rice is washed, the valve of the water outlet pipe 6 is opened to discharge the washed water from the water outlet pipe 6. The washed rice is located on the filter plate 11. Then the sealing plate 7 is opened so that the washed rice on the filter plate 11 can be discharged through the discharge port, thus realizing the washing of the rice. The height of the collection box 15 can be adjusted according to the water level. Therefore, different amounts of clean water are needed when washing different amounts of rice. This adjustment can better adapt to various situations. Moreover, after collecting the impurities, the collection box 15 can be directly removed from the fixing rod 13, which facilitates the unified treatment of the impurities.

[0027] Furthermore, the collection box 15 includes a connecting frame 153, with open sections on both the side walls and bottom. A filter frame 151 is rotatably connected to the surface of the connecting frame 153. The filter frame 151 has an "L"-shaped structure to cover the open sections on the side walls and bottom of the connecting frame 153. A rod 156 is inserted into the end of the connecting frame 153. The side wall of the filter frame 151 has a hole that matches the size of the rod 156. An opening 152 is formed on the side of the connecting frame 153 away from the open section. A baffle 154 is rotatably connected inside the opening 152. A rotating shaft 155 is fixedly inserted through the bottom of the baffle 154. Torsion springs are fitted at both ends of the rotating shaft 155, and the two ends of the torsion springs are respectively connected to the baffle 154 and the connecting frame 153. The frame 153 is fixedly connected. In actual use, the collection box 15 rotates with the stirring shaft 12. During the rotation, the baffle 154 is open due to the resistance of the water, so impurities can enter the collection box 15 through the opening 152. The impurities inside the collection box 15 are blocked by the filter frame 151, thus keeping the impurities in the collection box 15. When the collection box 15 stops rotating, the baffle 154 will block the opening 152 under the action of the torsion spring, so that the impurities will not come out from the opening 152. When cleaning the impurities inside the collection box 15, the collection box 15 can be directly removed, and then the insertion rod 156 can be pulled out to open the filter frame 151, so as to facilitate direct cleaning of the impurities inside.

[0028] Furthermore, a sleeve 9 is slidably fitted onto the surface of the stirring shaft 12, and a stirring rod 10 is fixedly installed on the surface of the sleeve 9. The motor 16 drives the stirring shaft 12 to rotate, the stirring shaft 12 drives the sleeve 9 to rotate, and the sleeve 9 drives the stirring rod 10 to rotate synchronously, thereby using the stirring rod 10 to stir the rice, thus facilitating the improvement of the rice washing effect.

[0029] Furthermore, two connecting rods 17 are fixedly installed at the bottom of the filter plate 11. Both connecting rods 17 slide through the bottom of the washing tank 1. A crossbar 18 is fixedly installed at the bottom end of the two connecting rods 17. A cylinder 19 is fixedly installed at the bottom of the washing tank 1. The output end of the cylinder 19 is fixedly connected to the crossbar 18. A through hole is opened at the center of the surface of the filter plate 11. The stirring shaft 12 passes through the through hole. A support leg 3 is fixedly installed at the bottom of the washing tank 1. A base plate 4 is fixedly installed at the bottom end of the support leg 3. During the washing process, the rice is always on the surface of the filter plate 11, that is, at the bottom of the water. Some impurities may be buried by the rice and unable to float to the surface. At this time, cylinder 19 is activated, which drives the crossbar 18 and connecting rod 17 to move upward. The connecting rod 17 drives the filter plate 11 to move upward, thereby moving the rice on the filter plate 11 upward. Then, cylinder 19 drives the filter plate 11 to suddenly move downward. At this time, the rice in the water will slowly sink under the action of buoyancy. During this process, the rice is in a scattered state, which helps the impurities inside the rice to float to the surface of the water, making it convenient to use. Since the sleeve rod is slidably sleeved on the surface of the stirring shaft 12, even if the filter plate 11 touches the sleeve rod and stirring rod 10 during the process, it will drive the sleeve rod and stirring rod 10 to move upward, without obstructing the movement of the filter plate 11.

[0030] Furthermore, a spring 8 is fixedly installed on the top of the sealing plate 7. The end of the spring 8 away from the sealing plate 7 is fixedly connected to the washing tank 1. The sealing plate 7 and the washing tank 1 are slidably connected. The sealing plate 7 is used to seal the discharge port. During the washing process, the sealing plate 7 is in a sealed state. When it is necessary to discharge the rice, the sealing plate 7 moves upward to open the discharge port. The discharge port is flush with the filter plate 11, so that the purpose of discharging the rice from the discharge port can be achieved. The spring 8 can make the sealing plate 7 subject to elastic force, thereby improving the sealing effect.

[0031] Furthermore, an inclined discharge plate 5 is fixedly installed on the side wall of the washing tank 1 relative to the sealing plate 7, and the top of the filter plate 11 is set as an inclined surface. By setting the discharge plate 5, the rice can be discharged along the discharge plate 5 when it comes out of the discharge port, which further improves the convenience of the device.

[0032] In summary, during use, rice is poured into the cleaning tank 1, and then an appropriate amount of water is added. The cleaning mechanism is installed on the fixed rod 13, where the collection box 15 is fixedly installed at the bottom of the screw 14. The distance between the collection box 15 and the connecting block 20 can be changed by rotating the screw 14. Therefore, the distance between the collection box 15 and the connecting block 20 can be adjusted according to the water level in the cleaning tank 1. Finally, the connecting block 20 is installed on the fixed rod 13, so that the collection box 15 is positioned at the water level. Then, the motor 16 is started, which drives the stirring shaft 12 to rotate. The stirring shaft 12 drives the fixed rod 13 to rotate, and the fixed rod 13 drives the screw 14 and the collection box 15 in the cleaning mechanism to rotate synchronously. When the collection box 15 rotates on the water surface, it can clean and collect impurities floating on the water surface. After the rice is washed, the valve of the water outlet pipe 6 is opened to discharge the washed water from the water outlet pipe 6. The washed rice is located on the filter plate 11. Then, the sealing plate 7 is opened so that the washed rice on the filter plate 11 can be discharged through the discharge port, thus realizing the washing of rice. The height of the collection box 15 can be adjusted according to the water level. Therefore, different amounts of clean water are needed when washing different amounts of rice. This adjustment can better adapt to various situations. Moreover, after collecting impurities, the collection box 15 can be directly removed from the fixing rod 13 for convenient unified treatment of impurities. In practical use, the stirring shaft 12 rotates. During rotation, the baffle 154 is open due to water resistance, allowing impurities to enter the collection box 15 through the opening 152. The impurities inside the collection box 15 are blocked by the filter screen 151, thus retaining them within the collection box 15. When the collection box 15 stops rotating, the baffle 154, under the action of the torsion spring, blocks the opening 152, preventing impurities from escaping. To clean the impurities inside the collection box 15, the collection box 15 can be directly removed, and the insert rod 156 can be pulled out to open the filter screen 151, facilitating direct cleaning of the internal impurities. The motor 16 drives the stirring shaft 12 to rotate, and the stirring shaft 12 drives the sleeve 9 to... The sleeve 9 rotates, causing the stirring rod 10 to rotate synchronously, thus stirring the rice and improving the washing effect. During the washing process, the rice remains on the surface of the filter plate 11, i.e., at the bottom of the water. Some impurities may be buried by the rice and unable to float to the surface. At this time, the cylinder 19 is activated, which moves the crossbar 18 and connecting rod 17 upward. The connecting rod 17 moves the filter plate 11 upward, thereby moving the rice on the filter plate 11 upward. Then, the cylinder 19 suddenly moves the filter plate 11 downward. At this time, the rice in the water will slowly sink under the buoyancy of the water. During this process, the rice is in a scattered state, which helps the impurities inside the rice to float to the surface, making it easier to use.Since the sleeve rod is slidably fitted onto the surface of the stirring shaft 12, even if the filter plate 11 encounters the sleeve rod and stirring rod 10 during operation, it will still cause the sleeve rod and stirring rod 10 to move upwards, without obstructing the movement of the filter plate 11. The sealing plate 7 is used to seal the discharge port. During the washing process, the sealing plate 7 is in a sealed state. When it is necessary to discharge the rice, the sealing plate 7 moves upwards, opening the discharge port and making it flush with the filter plate 11. Therefore, the rice can be discharged from the discharge port. The spring 8 provides elasticity to the sealing plate 7, improving the sealing effect. The discharge plate 5 allows the rice to be discharged along the discharge plate 5 when it comes out of the discharge port, further improving the convenience of the device.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
