[0001] This utility model relates to the field of rice processing and grading technology, and in particular to an energy-saving rice processing and grading 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 more than 90% of the nutrients required by the human body, making it a staple food for people in southern China. Rice undergoes multiple processes to remove the husk from the paddy, but during this process, some rice grains break and are not fully formed. Therefore, rice processing and grading equipment is needed to separate whole rice grains from broken rice.

[0003] In the existing technology, when processing rice for grading, workers need to sieve it multiple times, and different sieve screens with different aperture sizes need to be replaced during sieve processing. Furthermore, if the sieve holes become blocked, it is quite cumbersome and inconvenient to unblock them later. Utility Model Content

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides an energy-saving rice processing and grading device, including a grading and sealing screening box 3, multiple rotating shafts 8 are rotatably installed on the left and right sides of the grading and sealing screening box 3, a support frame 9 is fixedly installed on the rotating shafts 8, a feed hole 4 is opened on the top of the grading and sealing screening box 3, a discharge hole 5 is opened on the bottom of the grading and sealing screening box 3, the rotating shafts 8 and the support frame 9, and a rice grading vibrating screening component 1 is provided on the grading and sealing screening box 3, the rotating shafts 8 and the support frame 9.

[0031] The rice grading vibrating sieve assembly 1 includes a fixed cylinder 11, a spring 12, an anti-slip guide block 13, a guide slide rod 14, and a sieve frame 15. Multiple fixed cylinders 11 are fixedly installed on the top of the support frame 9. The spring 12 is fixedly installed on the bottom inner wall of the fixed cylinder 11. The anti-slip guide block 13 is fixedly installed on the spring 12. The guide slide rod 14 is fixedly installed on the top of the anti-slip guide block 13 and slides inside the fixed cylinder 11. The sieve frame 15 is fixedly installed on the top of the guide slide rod 14. The upper and lower sieve frames 15 are fixedly installed on the middle sieve frame 15 via connecting rods 28. The vibrating motor 16 drives the sieve frame 15 to vibrate, causing the rice to disperse quickly within the sieve frame 15, accelerating the passage of rice of the correct particle size through the sieve holes 17, and reducing sieve time. The guide slide rod 14 slides inside the fixed cylinder 11, and with the elastic support of the spring 12, ensures that the sieve frame 15 vibrates stably only in the vertical direction, preventing lateral displacement that could lead to rice accumulation.

[0032] In this embodiment, multiple hinges 6 are fixedly installed on the front side of the grading and sealing screening box 3, and an openable door 7 is fixedly installed on the hinges 6. A rice grading and vibrating screening component 1 is provided with a rice grading and anti-clogging screening component 2.

[0033] In this embodiment, the rice grading vibrating sieve assembly 1 also includes a vibrating motor 16, sieve holes 17, a sliding adjustment frame 18, a rice grading discharge hole 19, and fixing bolts 20. The vibrating motor 16 is fixedly installed at the bottom of the sieve frame 15 in the middle. Multiple sieve holes 17 are opened at the bottom of the sieve frame 15. The sliding adjustment frame 18 is slidably installed on the inner side of the sieve frame 15. The rice grading discharge hole 19 is opened at the top of the sliding adjustment frame 18. The fixing bolts 20 are threaded on one side of the sieve frame 15, and one end of the fixing bolts 20 abuts against the sliding adjustment frame 18. The sliding hole at the top of the fixed cylinder 11 limits the guide slide rod 14, ensuring that the sieve frame 15 vibrates only up and down, reducing ineffective energy consumption. Since the device can swing, the connecting rod 28 and the vibrating motor 16 will not cause the rice to accumulate during the grading process, and the rice will not accumulate inside the sieve holes 17, resulting in a better rice grading effect.

[0034] In this embodiment, the rice grading anti-clogging screening component 2 includes a fixed plate 21, an electric telescopic rod 22, a rack 23, and a transmission gear 24. The fixed plate 21 is fixedly installed on the right side of the grading and sealing screening box 3, the electric telescopic rod 22 is fixedly installed at the bottom of the fixed plate 21, the rack 23 is fixedly installed at the output end of the electric telescopic rod 22, and the transmission gear 24 is fixedly installed on the outside of the rotating shaft 8. The rack 23 and the transmission gear 24 mesh with each other.

[0035] In this embodiment, the rice grading anti-clogging screening component 2 also includes a protective cover 25, a lubricating oil filling hole 26, and a lubricating oil collection drawer 27. The protective cover 25 is fixedly installed on the right side of the grading and sealing screening box 3, the rack 23 is slidably installed on the inner side of the protective cover 25, the lubricating oil filling hole 26 is opened on the top of the protective cover 25, and the lubricating oil collection drawer 27 is slidably installed on the inner side of the protective cover 25.

[0036] In this embodiment, a feeding funnel is fixedly installed on the top of both the screening frame 15 and the feeding hole 4, and a discharge hole is opened on the top of the support frame 9; the feeding funnel allows rice to enter the interior of the screening frame 15 during the feeding process, and the discharge hole ensures that no rice residue will appear after screening.

[0037] In this embodiment, a guide groove is provided on the front side of the screening frame 15, and the sliding adjustment frame 18 is slidably installed on the inner side of the guide groove.

[0038] In this embodiment, the rice grading feeding hole 19 is attached to the sieving hole 17, and the lengths of the rice grading feeding hole 19 and the sieving hole 17 are the same. The sieving hole 17 at the bottom of the sieving frame 15 is attached to the rice grading feeding hole 19 at the top of the sliding adjustment frame 18. The sliding adjustment frame 18 can slide along the guide groove on the inner side of the sieving frame 15 to adjust the overlap range of the two to change the aperture of the sieving hole 17, so as to adapt to the grading requirements of rice with different particle sizes, such as brown rice, polished rice, and broken rice.

[0039] In this embodiment, a sliding hole is provided at the top of the fixed cylinder 11, and the guide slide rod 14 is slidably installed on the inner side of the sliding hole. The outer diameter of the anti-slip guide block 13 is larger than the inner diameter of the sliding hole. The anti-slip guide block 13 prevents the screening frame 15 from detaching from the fixed cylinder 11, thus avoiding equipment shutdown due to component detachment.

[0040] In this embodiment, a lubricating oil collection groove is provided on the right side of the protective cover 25, and a lubricating oil collection drawer 27 is slidably installed inside the lubricating oil collection groove; the protective cover 25 protects the rack 23 and the transmission gear 24 from dust contamination, and the lubricating oil filling hole 26 on its top facilitates the addition of lubricating oil, reducing wear on transmission components; the lubricating oil collection drawer 27 can collect excess lubricating oil, avoiding residue in the protective cover 25 that could cause component contamination or jamming, extending the service life of the device, and reducing maintenance frequency.

[0041] The specific operation is as follows: when grading whole rice and broken rice, manually control the sieving hole 17 at the top of the sieving frame 15 to fit with the rice grading discharge hole 19 at the bottom of the sliding adjustment frame 18. Manually push the sliding adjustment frame 18 to slide along the guide groove on the inner side of the sieving frame 15, and adjust the overlap range of the two to change the aperture of the sieving hole 17, so that broken rice can fall from the sieving hole 17, while whole rice can be retained. After adjustment, tighten the fixing bolt 20 to lock the position of the sliding adjustment frame 18 to avoid displacement during sieving and affecting the grading accuracy. After grading, the rice grading discharge hole 19 can be made to completely overlap with the sieving hole 17, allowing the graded rice to fall quickly. Adjusting the sliding adjustment frame 18 on each sieving frame 15 from bottom to top makes it convenient for workers to collect the rice by particle size, solving the problems of poor adaptability and cumbersome collection of traditional fixed aperture sieving devices.

[0042] The vibrating motor 16 drives the screening frame 15 to vibrate, causing the rice to disperse quickly within the screening frame 15 and accelerating the passage of rice of the correct particle size through the screening holes 17, thus reducing screening time. The guide rod 14 slides inside the fixed cylinder 11, and with the elastic support of the spring 12, the screening frame 15 vibrates stably only in the vertical direction, avoiding lateral displacement that could cause rice to accumulate. The anti-slip guide block 13 prevents the guide rod 14 from sliding out of the fixed cylinder 11, ensuring a continuous screening process. The discharge hole at the top of the support frame 9 prevents rice from remaining on the support structure, ensuring no waste after grading and improving processing efficiency. The connecting rod 28 allows a single vibrating motor 16 to drive multiple screening frames 15 to vibrate synchronously, and the connecting rod 28 also allows multiple screening frames 15 to swing with the rotating shaft 8, which can significantly reduce the energy consumption of the device.

[0043] The electric telescopic rod 22 drives the rack 23 to move. The rack 23 meshes with the transmission gear 24 on the outside of the rotating shaft 8, causing the rotating shaft 8 and the support frame 9 to swing. This allows the rice piled on the screening frame 15 to move left and right, preventing the screening holes 17 from clogging. This device drives the support frame 9 and multiple screening frames 15 to swing using only a single electric telescopic rod 22, which can effectively reduce working energy consumption. The protective cover 25 protects the rack 23 and transmission gear 24 from dust contamination. The lubricating oil filling hole 26 on its top facilitates the addition of lubricating oil, reducing wear on transmission components. The lubricating oil collection drawer 27 can collect excess lubricating oil, preventing residue in the protective cover 25 from causing component contamination or jamming, extending the service life of the device, and reducing maintenance frequency. Because the device can swing, the connecting rod 28 and the vibrating motor 16 will not cause rice to accumulate during the grading process, resulting in better rice screening effect.

[0044] The grading and sealing screening box 3 is connected to the door 7 via hinge 6, which allows for easy inspection or cleaning of internal components such as the screening frame 15 and sliding adjustment frame 18 without disassembling the entire device. The sealing design of the grading and sealing screening box 3 prevents rice dust from spilling out during the screening process, improving the processing environment and reducing dust pollution. The feed hole 4 and the feed funnel at the top of the screening frame 15 guide the rice to enter the screening frame 15 precisely, avoiding rice spillage and waste, while simplifying the feeding operation and reducing the labor intensity of the staff.

[0045] The sliding hole at the top of the fixed cylinder 11 limits the guide slide rod 14, ensuring that the screening frame 15 only vibrates up and down, reducing ineffective energy consumption; the anti-slip guide block 13 prevents the screening frame 15 from detaching from the fixed cylinder 11, avoiding equipment shutdown due to component detachment; the lubricating oil collection drawer 27 recovers excess lubricating oil, which can be reused, reducing resource waste and further demonstrating energy-saving characteristics.
