Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice processing technology, and in particular to a rice processing suction device. Background Technology
[0002] Rice is a finished product made from paddy through cleaning, hulling, milling, and finishing processes. The germ and aleurone layer of paddy contain nearly 64% of the rice's nutrients and over 90% of the nutrients needed by the human body, making it a staple food for people in southern China. Rice contains approximately 75% carbohydrates, 7%-8% protein, and 1.3%-1.8% fat, and is also rich in B vitamins. The carbohydrates in rice are primarily starch, and the protein is mainly 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 is processed by removing the outer husk of rice to form rice. However, after the rice comes out of the processing machine, some husks are still mixed inside the rice and have not been completely removed. Therefore, a husk suction device is needed to remove the husks in subsequent processing. However, some husks are wrapped around the surface of the rice or some husks are stuck to the surface of the rice, which makes it impossible for the husk suction device to remove them effectively, which is not conducive to processing. Utility Model Content
[0004] The purpose of this invention is to provide a rice husk suction device that solves the problem in the prior art where rice husks are wrapped around the surface of the rice or partially adhered to the surface of the rice, making it impossible for the suction device to effectively remove them and hindering the processing operation.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A rice processing hulling device includes a connecting box with a U-shaped structure. A fixing frame is fixedly installed on the top of the connecting box, and a cylinder is fixedly installed on the surface of the fixing frame. A connecting frame is fixedly installed at the output end of the cylinder. A dust suction structure and a beating mechanism are provided on the surface of the connecting frame. The beating mechanism includes a pressure plate evenly distributed at the bottom of the connecting frame. A spring is fixedly installed on the top of the pressure plate and fixedly connected to the top of the connecting frame.

A fixing frame is provided between the two arms of the connecting box, and a sieve frame is provided on the surface of the fixing frame. A driving mechanism for driving the fixing frame to vibrate is provided on the surface of the connecting box.
[0007] Preferably, the driving mechanism includes a motor, which is fixedly mounted on the side wall of the connecting box.

The two connecting plates are slidably connected to the two arms of the connecting box, and the eccentric wheels are in contact with the connecting plates.
[0008] Preferably, the vacuuming structure includes a vacuum cleaner, which is fixedly installed at the bottom of the fixed frame. The vacuum cleaner's suction port is connected to a suction pipe, and a connecting pipe is evenly connected to the surface of the suction pipe. The bottom end of the connecting pipe is connected to a vacuum shell. The surface of the connecting frame is evenly provided with mounting grooves that are adapted to the size of the vacuum shell. The pressure plate and the mounting grooves are alternately arranged.
[0009] Preferably, a handle is fixedly installed at the top of the screen frame near the port, and a rotating shaft is fixedly installed at the end of the screen frame away from the handle. The screen frame is rotatably connected to the fixed frame through the rotating shaft.

[0027] Reference Figure 1-6 A rice processing hulling device includes a connecting box 1 with a U-shaped structure. A fixed frame 2 is fixedly mounted on the top of the connecting box 1. A cylinder 4 is fixedly mounted on the surface of the fixed frame 2. A connecting frame 13 is fixedly mounted on the output port of the cylinder 4. A dust-collecting structure and a beating mechanism are provided on the surface of the connecting frame 13. The beating mechanism includes a pressure plate 14 evenly distributed at the bottom of the connecting frame 13. A spring 16 is fixedly mounted on the top of the pressure plate 14, and the top of the spring 16 is fixedly connected to the connecting frame 13. A telescopic sleeve is provided inside the spring 16, and both ends of the telescopic sleeve are fixedly connected to the pressure plate 14 and the connecting frame 13, respectively. A fixed frame 5 is provided between the two arms of the connecting box 1. A sieve frame 6 is provided on the surface of the fixed frame 5. A driving mechanism for vibrating the fixed frame 5 is provided on the surface of the connecting box 1. In use, rice is poured onto the surface of the sieve frame 6, and then the dust-collecting structure is activated to absorb the rice hulls. Simultaneously, cylinder 4 is activated, causing the entire connecting frame 13 to move up and down. When cylinder 4 moves the connecting frame 13 down, it also moves the pressure plate 14 in the beating mechanism down synchronously. The pressure plate 14 beats the rice in the sieve frame 6, which helps to separate the rice husks from the rice. Once the rice husks and rice are separated, the husks can be removed with the help of the dust collection structure, making it convenient to operate. The pressure plate 14 and the connecting frame 13 are connected by a spring 16, so that the spring 16 can be compressed during the beating of the rice, thereby improving the beating effect and avoiding the phenomenon that the pressure plate 14 cannot fully contact the rice due to the rigid connection between the pressure plate 14 and the connecting frame 13. At the same time, a drive mechanism is also provided in the connecting box 1, which can be used to vibrate the entire fixed frame 5, thereby vibrating the sieve frame 6 and removing stones or other heavier impurities mixed in the rice, improving practicality.
[0028] Furthermore, the drive mechanism includes a motor 8, which is fixedly mounted on the side wall of the connecting box 1. A transmission shaft 10 is rotatably passed through the surface of the connecting box 1. The output shaft port of the motor 8 is fixedly connected to the transmission shaft 10. Two eccentric wheels 9 are fixedly mounted on the surface of the transmission shaft 10. Connecting plates 7 are fixedly mounted on both sides of the fixed frame 5. The two connecting plates 7 are slidably connected to the two arms of the connecting box 1 respectively. The eccentric wheels 9 are in contact with the connecting plates 7. In use, when the drive mechanism is started, the motor 8 drives the transmission shaft 10 to rotate. The transmission shaft 10 drives the eccentric wheels 9 to rotate. The eccentric wheels 9 drive the fixed frame 5 and the connecting plates 7 to reciprocate up and down between the two arms of the connecting box 1.
[0029] Furthermore, the dust collection structure includes a vacuum cleaner 3, which is fixedly installed at the bottom of the fixed frame 2. The vacuum cleaner 3 has a suction port connected to a suction pipe 11, and a connecting pipe 12 is evenly connected to the surface of the suction pipe 11. The bottom end of the connecting pipe 12 is connected to a dust collection shell 15. The surface of the connecting frame 13 is evenly provided with mounting grooves that are adapted to the size of the dust collection shell 15. The pressure plate 14 and the mounting grooves are alternately arranged. When the dust collection structure is in use, the vacuum cleaner 3 is started, and the vacuum cleaner 3 achieves the purpose of adsorbing the rice husks mixed in the rice through the suction pipe 11, the connecting pipe 12 and the dust collection shell 15. Multiple dust collection shells 15 are provided to improve the adsorption effect.
[0030] Furthermore, a handle 17 is fixedly installed on the top of the sieve frame 6 near the port. A rotating shaft is fixedly installed on the end of the sieve frame 6 away from the handle 17. The sieve frame 6 is rotatably connected to the fixed frame 5 through the rotating shaft. By setting the handle 17, the entire sieve frame 6 can rotate around the rotating shaft, thereby tilting the sieve frame 6, which helps to pour out the rice in the sieve frame 6. During normal use, the end of the sieve frame 6 away from the rotating shaft is interference-fitted with the fixed frame 5. Therefore, the vibration of the fixed frame 5 can make the entire sieve frame 6 vibrate synchronously, and the sieve frame 6 will not rotate during the vibration.
[0031] Furthermore, the screen frame 6 includes an outer frame and an inner filter screen. The filter screen is fixedly installed inside the frame. The bottom of the fixed frame 5 is evenly provided with crossbars to support the filter screen, reducing the possibility of the filter screen being damaged due to full force during the tapping process of the pressure plate 14.
[0032] Furthermore, the bottom wall of the connecting box 1 is set as an inclined surface so that impurities falling from the screen frame 6 can slide out using the inclined surface.
[0033] In summary, during use, rice is poured onto the surface of the sieve frame 6, and then the suction structure is activated to adsorb the rice husks. Simultaneously, cylinder 4 is activated, causing the entire connecting frame 13 to move up and down. When cylinder 4 moves the connecting frame 13 down, it also moves the pressure plate 14 in the beating mechanism down synchronously, using the pressure plate 14 to beat the rice in the sieve frame 6, thus helping to separate the rice husks from the rice. Once the rice husks and rice are separated, the suction structure can be used to remove the rice husks, making operation convenient. The pressure plate 14 and the connecting frame 13 are connected by a spring 16, so that the spring 16 can be compressed during the beating of the rice, thereby improving the beating effect and avoiding the phenomenon that the pressure plate 14 cannot fully contact the rice due to the rigid connection between the pressure plate 14 and the connecting frame 13. At the same time, a drive mechanism is also provided in the connecting box 1, which can be used to vibrate the entire fixed frame 5, thereby causing the sieve frame 6 to move up and down. Vibration removes stones or other heavier impurities mixed in the rice, improving practicality. During use, the drive mechanism starts the motor 8, which drives the transmission shaft 10 to rotate. The transmission shaft 10 then drives the eccentric wheel 9 to rotate, which in turn drives the fixed frame 5 and the connecting plate 7 to vibrate back and forth between the two arms of the connecting box 1. During use, the vacuum cleaner 3 starts the vacuum cleaner, which uses the suction pipe 11, connecting pipe 12, and suction shell 15 to absorb rice husks mixed in the rice. Multiple suction shells 15 are provided to improve the absorption effect. The handle 17 allows the entire sieve frame 6 to rotate around the pivot, tilting the sieve frame 6 and facilitating the pouring of rice out. During normal use, the end of the sieve frame 6 furthest from the pivot is interference-fitted with the fixed frame 5. Therefore, the vibration of the fixed frame 5 allows the entire sieve frame 6 to vibrate synchronously, preventing rotation during vibration.
