Description

Technical Field

[0001] This utility model relates to the field of late-season indica rice processing technology, specifically to a processing device for improving the uniformity of late-season indica rice. Background Technology

[0002] Late-season indica rice is made from non-glutinous late-season indica rice. It has distinctive appearance characteristics: the grains are long and flat, with a fine texture, and are generally transparent or semi-transparent, with a small white belly and a higher proportion of hard grains. In terms of eating quality, late-season indica rice is quite sticky, and after cooking, it has a soft yet chewy texture without being sticky, and a delicate and delicious taste, making it very popular with consumers. At the same time, late-season indica rice also has high nutritional value, rich in protein, fat, riboflavin, niacin, minerals, and other nutrients, as well as a small amount of carbohydrates. During the processing of late-season indica rice, screening and other processes are required to ensure its uniformity.

[0003] A search revealed that patent CN220111828U discloses a rice processing device for improving rice uniformity. While this device, through its blowing and filtering mechanisms, achieves the goal of improving rice uniformity by removing surface debris and impurities, it has several shortcomings in practical use. The device directly injects late-season indica rice, which easily leads to accumulation within the device, affecting processing efficiency and effectiveness. Furthermore, it cannot effectively remove dust and husks adhering to the surface of the rice, resulting in incomplete cleaning and impacting rice quality. Additionally, the feeding and processing processes easily generate dust and debris, which not only pollutes the processing environment but may also adversely affect the health of operators. In conclusion, existing late-season indica rice processing devices have several deficiencies and urgently require improvement and refinement. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a processing device to improve the uniformity of late indica rice, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A processing device for improving the uniformity of late-season indica rice includes a screening box, a screen installed inside the screening box, a vibration motor installed at the bottom of the outer surface of the screening box, and a mounting base provided at the bottom end of the screening box.

[0007] A protective cover is fixedly installed on the screening box. A second gas collection hood is installed on the top surface of the inner wall of the protective cover. A blow pipe is installed on the side surface of the inner wall of the protective cover. An air outlet is opened on the blow pipe. A feeding box is provided on the protective cover. A feeding pipe is embedded in the side surface of the feeding box. A first gas collection hood is installed inside the feeding box. A discharge pipe is embedded in the bottom surface of the feeding box. A drive motor is installed on the feeding box. A rotating shaft is provided on the output shaft of the drive motor.

[0008] The mounting base is equipped with a processing box and a first air pump via a mounting plate. The processing box is respectively embedded with a first extraction tube and a second extraction tube.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, both ends of the outer surface of the screening box are equipped with brackets via damping springs, and the bottom end of the brackets is fixedly mounted on the mounting base.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] Damping springs effectively absorb the vibration energy generated by the vibratory motor during operation, reducing the vibration transmission from the screening box to the mounting base and surrounding equipment. Through the elastic buffering and damping effect of the springs, the stability of equipment operation is improved, reducing the risk of component loosening or damage caused by severe vibration, while also reducing noise pollution and extending equipment lifespan. Furthermore, a stable vibration environment helps the screen maintain a uniform screening amplitude, further improving the screening accuracy and uniformity of late-season indica rice.

[0013] Furthermore, the bottom end face of the discharge pipe is embedded in the protective cover, and the feed box is connected to the protective cover through the discharge pipe.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The interconnected design of the discharge pipe ensures that late-season indica rice flows smoothly from the feed hopper into the protective cover, preventing blockages or accumulation during transport. This structural design guarantees the continuity of the processing flow, allowing the material to enter the subsequent screening and cleaning stages in a timely manner.

[0016] Furthermore, the rotating shaft is disposed inside the feed box and the discharge pipe, and a beater is fixedly installed on the rotating shaft, with a silicone pad attached to the beater.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] When the drive motor rotates the shaft, the silicone pads on the beater bar periodically beat the late-season indica rice in the feed hopper and discharge pipe. The elastic material of the silicone pads effectively breaks up clumps of rice grains, preventing material accumulation, and avoids damage to the rice grains due to hard beating, protecting their integrity. The beating also separates debris and dust from the material. Furthermore, the beating action loosens the rice grains as they fall, promoting uniform material distribution and providing a better feeding condition for subsequent screening processes, thereby improving screening efficiency and uniformity.

[0019] Furthermore, a second air pump is installed on the outer surface of the protective cover, and an air inlet pipe is provided on the second air pump. The end of the air inlet pipe facing away from the second air pump is embedded and fixed inside the blow pipe.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The second air pump delivers compressed air to the blowpipe through the air inlet pipe, and the airflow from the outlet forms a directional airflow field within the protective cover. This airflow disperses the rice grains during their descent, preventing material agglomeration and ensuring they are evenly spread on the screen, thus improving the screening effect. Simultaneously, the airflow blows off debris, dust, and other impurities adhering to the surface of the rice grains, aiding in material cleaning and further enhancing the uniformity of the late-season indica rice.

[0022] Furthermore, the first air pump is provided with an exhaust pipe, and the end of the exhaust pipe facing away from the first air pump is embedded in the processing box. The processing box is equipped with a filter bag, and a sealing cover is installed on the processing box by bolts.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The first air pump draws dust-laden gas into the processing chamber through an exhaust pipe. Filter bags inside the chamber intercept dust particles, separating the gas from the dust. This design constitutes a complete dust removal system, effectively collecting dust generated during processing, reducing dust concentration in the working environment, and meeting environmental protection and safety production requirements. Simultaneously, the purified gas can be discharged through the exhaust pipe, preventing dust accumulation inside the equipment, reducing the risk of equipment failure, and preventing secondary contamination of rice grains by dust, thus ensuring product quality.

[0025] Furthermore, the end of the first extraction tube facing away from the processing box is embedded in the first gas collection hood, and the end of the second extraction tube facing away from the processing box is embedded in the second gas collection hood.

[0026] The beneficial effects of adopting the above-mentioned further solutions are:

[0027] The first and second dust collection hoods are respectively installed inside the feed box and the protective cover, which can specifically collect the dust generated during feeding and screening. Through the first and second extraction pipes, the dust is promptly drawn into the processing box for filtration. Compared to a single dust collection point, this structure can more comprehensively control dust diffusion and further improve the working environment.

[0028] This invention provides a processing device for improving the uniformity of late-season indica rice. It has the following beneficial effects:

[0029] In the vibration and screening process, the damping spring, in conjunction with the support frame, effectively absorbs the energy generated by the vibration motor, reduces vibration transmission, improves equipment stability, reduces the risk of failure and noise pollution, extends service life, and at the same time ensures that the screen screening amplitude is uniform, improving screening accuracy and uniformity.

[0030] In terms of material transfer, the discharge pipe connects the feed box and the protective cover to ensure smooth transfer of late-season indica rice, avoid blockage and accumulation, ensure continuous processing, and lay the foundation for subsequent processes.

[0031] During material pretreatment, the drive motor drives the rotating shaft and the beater rod, using the elasticity of the silicone pad to beat the rice grains. This not only breaks up clumps and separates debris and dust, but also protects the integrity of the rice grains, making them loose and uniform, optimizing the feeding state, and improving screening efficiency and uniformity.

[0032] In terms of airflow processing, the second air pump forms a directional airflow field through the blowpipe, which disperses the rice grains to prevent them from agglomerating and allows them to spread evenly on the screen. At the same time, it blows off surface impurities, further improving uniformity.

[0033] In terms of dust removal and environmental protection, the first air pump, together with the filter bags in the treatment box, forms a dust removal system that collects dust, reduces dust concentration, meets environmental and safety requirements, prevents dust accumulation and secondary pollution, and ensures product quality.

[0034] The dust collection system adopts a dual-collection hood design. The first and second collection hoods collect dust during the feeding and screening processes, respectively, and send it to the treatment box for filtration through the extraction pipe. Compared with a single dust collection point, this system provides more comprehensive control over dust diffusion and improves the working environment. Attached Figure Description

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0045] Example 1

[0046] A processing device for improving the uniformity of late indica rice includes a screening box 2, a screen 203 installed inside the screening box 2, a vibration motor 204 installed at the bottom of the outer surface of the screening box 2, and a mounting base 1 provided at the bottom end of the screening box 2.

[0047] A protective cover 3 is fixedly installed on the screening box 2. A second gas collection hood 301 is installed on the top surface of the inner wall of the protective cover 3. A blow pipe 302 is installed on the side surface of the inner wall of the protective cover 3. An air outlet 303 is opened on the blow pipe 302. A feed box 4 is provided on the protective cover 3. A feed pipe 402 is embedded in the side surface of the feed box 4. A first gas collection hood 404 is installed inside the feed box 4. A discharge pipe 401 is embedded in the bottom surface of the feed box 4. A drive motor 403 is installed on the feed box 4. A rotating shaft 405 is provided on the output shaft of the drive motor 403.

[0048] The processing box 5 and the first air pump 503 are mounted on the mounting base 1 via the mounting plate 502. The first extraction tube 504 and the second extraction tube 505 are respectively embedded in the processing box 5.

[0049] Both ends of the outer surface of the screening box 2 are equipped with brackets 202 via damping springs 201. The bottom end of the brackets 202 is fixedly mounted on the mounting base 1. The damping springs 201 can effectively absorb the vibration energy generated by the vibrating motor 204 during operation, reducing the vibration transmission from the screening box 2 to the mounting base 1 and surrounding equipment. Through the elastic buffering and damping effect of the damping springs 201, the stability of equipment operation can be improved, reducing the risk of component loosening or damage caused by severe vibration, while also reducing noise pollution and extending the service life of the equipment. In addition, a stable vibration environment helps the screen 203 maintain a uniform screening amplitude, further improving the screening accuracy and uniformity of late indica rice.

[0050] The bottom end of the discharge pipe 401 is embedded inside the protective cover 3. The feed box 4 is connected to the protective cover 3 through the discharge pipe 401. The interconnection design of the discharge pipe 401 ensures that the late-season indica rice falls smoothly from the feed box 4 into the protective cover 3, preventing blockage or accumulation of materials during transmission. This structural design ensures the continuity of the processing flow, allowing materials to enter the subsequent screening and cleaning stages in a timely manner.

[0051] A rotating shaft 405 is installed inside the feed box 4 and the discharge pipe 401. A tapping rod 406 is fixedly mounted on the rotating shaft 405, and a silicone pad is attached to the tapping rod 406. When the drive motor 403 drives the rotating shaft 405 to rotate, the silicone pad on the tapping rod 406 will periodically tap the late-season indica rice in the feed box 4 and the discharge pipe 401. The elastic material of the silicone pad can effectively break up clumps of rice grains, prevent material accumulation, and avoid damage to rice grains due to hard tapping, thus protecting the integrity of the rice grains. Furthermore, the tapping action can separate debris and dust from the material. In addition, the tapping action makes the rice grains more loose during the fall, promoting uniform material distribution and providing a better feeding condition for subsequent screening processes, thereby improving screening efficiency and uniformity.

[0052] Example 2

[0053] To collect and treat debris and dust during feeding and processing, and to disperse and prevent material accumulation as it falls, for example, such as Figures 1 to 4 As shown, this utility model also includes:

[0054] A second air pump 6 is installed on the outer surface of the protective cover 3. The second air pump 6 has an air inlet pipe 601. The end of the air inlet pipe 601 facing away from the second air pump 6 is embedded and fixed inside the blowpipe 302. The second air pump 6 delivers compressed air to the blowpipe 302 through the air inlet pipe 601. The airflow ejected from the outlet 303 can form a directional airflow field within the protective cover 3. This airflow can disperse the rice grains during the falling process, preventing material agglomeration and ensuring they are evenly spread on the screen 203, thereby improving the screening effect. Simultaneously, the airflow can blow off debris, dust, and other impurities adhering to the surface of the rice grains, assisting in cleaning the material and further improving the uniformity of the late-season indica rice.

[0055] The first air pump 503 is equipped with an exhaust pipe 501. One end of the exhaust pipe 501, away from the first air pump 503, is embedded inside the processing box 5. Filter bags are installed inside the processing box 5, and a sealing cover is bolted to the processing box 5. The first air pump 503 draws dust-laden gas into the processing box 5 through the exhaust pipe 501. The filter bags inside the box intercept dust particles, achieving separation of gas and dust. This design constitutes a complete dust removal system, effectively collecting dust generated during processing, reducing dust concentration in the working environment, and meeting environmental protection and safe production requirements. Simultaneously, the purified gas can be discharged through the exhaust pipe 501, preventing dust accumulation inside the equipment, reducing the risk of equipment failure, preventing secondary contamination of rice grains by dust, ensuring product quality, and allowing for replacement and maintenance of the internal filter bags by disassembling the sealing cover.

[0056] The first extraction pipe 504, with one end facing away from the processing box 5, is embedded inside the first dust collection hood 404. The second extraction pipe 505, with one end facing away from the processing box 5, is embedded inside the second dust collection hood 301. The first dust collection hood 404 and the second dust collection hood 301 are respectively located inside the feed box 4 and the protective cover 3, allowing for targeted collection of dust generated during feeding and screening. Through the first extraction pipe 504 and the second extraction pipe 505, dust is promptly drawn into the processing box 5 for filtration. Compared to a single dust collection point, this structure provides more comprehensive control over dust diffusion, further improving the working environment.

[0057] Working principle:

[0058] Feeding and Pretreatment

[0059] Late-season indica rice enters the feeding box 4 through the feeding pipe 402. The drive motor 403 starts and drives the rotating shaft 405 to rotate, so that the beating rod 406 (with a silicone pad attached to its surface) fixed on it periodically beats the rice grains.

[0060] The patting action can break up clumps of rice grains, separate debris and dust, and at the same time protect the integrity of the rice grains, making them looser and more even as they fall.

[0061] The first dust collector hood 404 collects the dust generated during the feeding process and sends the dust into the processing box 5 through the first extraction pipe 504.

[0062] Material transfer

[0063] The pre-treated rice grains fall from the feed box 4 into the protective cover 3 through the discharge pipe 401. The interconnected design of the discharge pipe 401 ensures smooth material transmission, avoids blockage and accumulation, and ensures continuous processing.

[0064] Airflow processing and screening

[0065] The second air pump 6 delivers compressed air to the blow pipe 302 through the air inlet pipe 601, and the air outlet 303 sprays out airflow, forming a directional airflow field inside the protective cover 3.

[0066] The airflow disperses the falling rice grains, preventing them from clumping together and allowing them to spread evenly on the screen 203. At the same time, it blows off debris, dust, and other impurities attached to the surface of the rice grains.

[0067] The vibrating motor 204 operates, driving the screen 203 to vibrate and sieve the rice grains. The damping spring 201 and the support 202 absorb the vibration energy, reduce vibration transmission, improve equipment stability, ensure uniform sieving amplitude of the screen 203, and improve sieving accuracy.

[0068] Dust removal and dust collection

[0069] The first air pump 503 draws dust-laden gas into the treatment box 5 through the exhaust pipe 501. The filter bag inside the box intercepts dust particles, achieving separation of gas and dust. The purified gas is then discharged, preventing secondary dust pollution.

[0070] The second dust collector hood 301 collects the dust generated during the screening process and sends the dust into the treatment box 5 through the second extraction pipe 505. The dust is filtered and treated together with the dust from the feeding process, thus comprehensively controlling the dust diffusion and improving the working environment.
