Description

Technical Field

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

[0002] Rice is one of the world's most important food crops, especially in Asia, where it is an indispensable staple food. With the development of agricultural mechanization, rice processing methods have undergone tremendous changes. From traditional manual processing to modern mechanized processing, rice processing technology has gradually become more efficient, automated, and refined. However, improving processing efficiency, reducing grain breakage, and optimizing broken rice processing techniques remain technical challenges. Automated broken rice processing devices have emerged as a key piece of equipment for improving the quality and efficiency of rice processing.

[0003] I. Traditional Rice Processing Techniques and Their Problems

[0004] Traditional rice processing typically includes steps such as hulling, peeling, polishing, grading, and packaging. Hulling and peeling are the most basic steps, while subsequent refining mainly involves screening and grading to remove substandard rice grains. During these steps, a certain amount of broken rice is produced after the rice is processed by equipment such as rice milling machines and rice sieves.

[0005] Broken rice generally refers to rice grains that have been damaged during processing. These broken rice grains differ from whole rice grains in appearance, texture, and nutritional composition. While broken rice has some value in certain food processing applications, for the high-end rice market, a lower proportion of broken rice enhances the overall value of the rice. Therefore, reducing the generation of broken rice has become an important goal in rice processing.

[0006] In traditional rice processing, the handling of broken rice is often a process requiring significant human intervention, lacking automation and precise control. During processing, it is difficult to monitor and regulate broken rice production in real time, and due to equipment limitations, the efficiency of broken rice sorting and recycling is low, resulting in uneven quality of processed rice grains and impacting the market competitiveness of the rice.

[0007] II. The Impact of Broken Rice

[0008] The formation of broken rice not only affects the appearance and commercial value of rice, but also, to some extent, its nutritional composition. Although the nutritional components of broken rice are not significantly different from those of whole grains, broken rice is usually more prone to oxidation due to its breakage, leading to a greater loss of components such as fat and protein. Furthermore, the smaller size of broken rice particles makes it more susceptible to moisture absorption and spoilage, significantly shortening its shelf life. Therefore, the recycling and processing of broken rice is particularly important.

[0009] A high proportion of broken rice not only affects the market price of rice but also consumer acceptance. In some high-end rice markets, consumers have high requirements for the integrity of rice grains, and an excessively high proportion of broken rice reduces the market competitiveness of the rice. Therefore, reducing the generation of broken rice and effectively recycling and processing it are key to improving the quality of rice processing and enhancing market competitiveness.

[0010] III. The need for automated broken rice processing

[0011] With the continuous development of automation technology, modern rice processing equipment has gradually achieved partial automation. Especially in the broken rice processing stage, the introduction of automation technology helps improve the precision and efficiency of rice processing. Automated broken rice processing devices can accurately classify and separate rice grains according to their size, shape, quality, and other characteristics, thereby achieving effective recycling and processing of broken rice. This equipment can automatically adjust its operating parameters to reduce the generation of broken rice and optimize the overall processing quality of the rice.

[0012] In rice processing, handling broken rice involves more than just screening and grading; it also involves separating broken rice from whole grains. Traditional manual methods rely heavily on operator experience and skill, resulting in relatively low precision and efficiency. Automated broken rice processing devices, by incorporating advanced sensor technology, automatic control systems, and intelligent algorithms, can monitor the amount of broken rice in real time and automatically adjust processing parameters based on the data, thereby reducing broken rice production and improving rice quality.

[0013] In the current rice processing field, existing broken rice processing technologies face numerous problems that urgently need to be addressed. Regarding the feeding stage, the lack of a scientifically sound material dispersion and guidance mechanism often leads to material accumulation and blockage at the feed inlet or feeding channel, causing frequent interruptions to the entire processing flow and severely impacting processing efficiency. Even more concerning is the dust pollution problem. Due to inadequate dust removal methods and flawed designs in ventilation systems and filtration systems, dust carried by the rice and dust generated during processing cannot be effectively controlled, permeating the production environment and endangering the health of operators. Summary of the Invention

[0014] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automated broken rice processing device for rice processing. This device solves the problems of easy clogging of the feed, poor impurity separation, and high dust pollution in existing broken rice processing technologies.

[0015] To achieve the above objectives, the present invention provides the following technical solution:

[0016] An automated broken rice processing device for rice processing includes a base plate and a feeding box. A screening box is fixedly connected to the top of the base plate, and a feeding hopper is provided at the top of the feeding box. A motor is installed on the left outer wall of the feeding box, and a rotating shaft is fixedly connected to the drive section of the motor. Multiple diverting plates are fixedly connected to the outer wall of the rotating shaft. A dust collection box is fixedly connected to the bottom of the feeding box, and a baffle plate is provided on the rear side of the dust collection box. A dust collection component is provided on the front outer wall of the dust collection box.

[0017] Furthermore, the dust removal assembly includes a second motor fixedly connected to the outer wall of the front side of the dust removal box, a rotating rod fixedly connected to the drive end of the second motor, and a fan fixedly connected to the outer wall of the rotating rod.

[0018] Furthermore, a collection box is fixedly connected to the rear outer wall of the dust collection box, and a filter screen is fixedly connected to the rear side of the collection box.

[0019] Furthermore, the top of the screening box is fixedly connected to the bottom of the feed box, a motor is installed on the left outer wall of the screening box, a rotating shaft is fixedly connected to the drive end of the motor, and cams are fixedly connected to the left and right ends of the rotating shaft.

[0020] Furthermore, sleeves are fixedly connected to the four corners of the bottom of the inner wall of the screening box, and sliding rods are slidably connected to the inner wall of the sleeves, and springs are provided on the inner wall of the sleeves.

[0021] Furthermore, the bottom end of the spring is connected to the inner wall of the sleeve, and the top end of the spring is connected to the bottom end of the sliding rod.

[0022] Furthermore, a discharge plate is fixedly connected to the top of the sliding rod, connecting rods are fixedly connected to the four corners of the top of the discharge plate, and a screening plate is fixedly connected to the top of the connecting rod.

[0023] Furthermore, a first discharge port is provided on the upper end of the front outer wall of the screening box, and a second discharge port is provided on the lower end of the front end of the screening box.

[0024] The initial purpose of developing this solution was to address the problems of low efficiency in handling broken rice, incomplete dust removal, and excessive manual intervention in traditional rice processing. Rice processing requires separating whole rice grains from broken rice and removing dust and impurities. Traditional equipment suffers from drawbacks such as uneven screening vibration, disconnect between dust removal and screening processes, and low levels of automation.

[0025] To solve the above problems, the equipment is broken down into four functional modules: feeding, dust removal, screening, and unloading, and automation is achieved through structural linkage.

[0026] Feeding module:

[0027] The system uses a motor to drive the splitter plate (rotating shaft + splitter plate), which distributes the rice evenly through centrifugal force, thus preventing the rice from piling up.

[0028] The feeding box and the dust collection box are directly connected: Gravity is used to make the rice fall naturally to the dust collection stage, reducing the energy consumption of transmission.

[0029] Dust removal module:

[0030] Fan and filter combination design: The motor drives the fan to generate negative pressure airflow, which sucks light dust into the collection box behind the filter, achieving dynamic dust removal.

[0031] Baffle assistance: An inclined baffle is installed at the rear of the dust collection box to extend the rice residence time and improve the dust removal effect.

[0032] Screening module:

[0033] Cam-spring vibration system: The motor drives the cam to periodically squeeze the screening plate (transmitted through the connecting rod and sliding rod), combined with the buffer of the spring in the sleeve, to form flexible vibration and reduce damage to broken rice.

[0034] Double-layer unloading design: After the screening plate separates whole rice grains from broken rice, the inclined unloading plate guides rice grains of different sizes to the first discharge port (whole rice) and the second discharge port (broken rice).

[0035] Dynamic dust removal and screening are linked:

[0036] The dust collection box is located directly above the screening box. After the rice is dusted, it immediately enters the screening station to prevent dust from re-adhering.

[0037] The fan airflow direction is set opposite to the direction in which the rice falls, which enhances the separation of impurities.

[0038] Design of flexible vibration systems:

[0039] Sleeve-sliding rod-spring structure: By releasing elastic potential energy through spring compression, the rigid impact of the cam is converted into a stable amplitude of the screening plate, reducing equipment wear.

[0040] Four-corner symmetrical support: The four corners of the screening plate are fixed to the sliding rods by connecting rods to ensure uniform vibration and prevent local deformation of the screen.

[0041] Spatial compact layout:

[0042] The feeding hopper, dust collector, and screening box are arranged vertically from top to bottom, reducing the horizontal space occupied and facilitating production line integration.

[0043] This solution achieves high efficiency and low loss in broken rice processing through process integration (dust removal-screening integration), structural synergy (flexible vibration system), and automated drive (multi-motor linkage), significantly improving production cleanliness and equipment stability. Its core value lies in replacing traditional complex control systems with innovative mechanical structures, making it suitable for cost reduction and efficiency improvement needs in small and medium-sized processing scenarios.

[0044] This utility model has the following beneficial effects:

[0045] 1. High-efficiency screening and low breakage of rice:

[0046] Flexible vibrating screening system: Through the combination of a motor-driven three-cam and a sleeve-spring buffer structure, the screening plate achieves uniform and flexible vibration, which can effectively separate broken rice from whole rice grains, reduce the physical damage to rice grains caused by mechanical vibration, and maintain the integrity rate of rice grains.

[0047] Anti-clogging design: The diversion plate (driven by motor) evenly distributes rice during the feeding stage, avoiding accumulation that could cause clogging of the screening plate and improving continuous operation capability;

[0048] 2. Integrated dust removal and screening operation:

[0049] Dynamic negative pressure dust removal: The motor drives the fan to generate reverse airflow, which, together with the filter and collection box, removes dust and impurities simultaneously as the rice falls. It has high dust removal efficiency and requires no additional power equipment.

[0050] Seamless process integration: The dust collection box and screening box are vertically connected, allowing rice to directly enter the screening process after dust removal, reducing the risk of secondary dust pollution;

[0051] 3. Automation and ease of operation:

[0052] Multi-motor linkage control: Feed diversion, dust removal and screening are driven by independent motors, and parameters can be adjusted individually (such as the speed of the diversion plate and the vibration frequency) to adapt to different rice varieties and processing needs;

[0053] Dual discharge port design: The whole rice grains (first discharge port) and broken rice (second discharge port) after screening are automatically discharged separately, eliminating the need for manual sorting and reducing labor intensity;

[0054] 4. Compact structure and convenient maintenance:

[0055] Modular layout: The feeding, dust removal and screening modules are integrated from top to bottom, which takes up little space and is easy to expand or modify the production line;

[0056] Easy to disassemble and clean: The collection box and filter screen can be quickly disassembled and cleaned. The screening plate is fixed by a connecting rod, making it easy to replace screens with different aperture sizes to meet diverse processing needs.

[0057] 5. Energy-saving and low-cost advantages

[0058] Synergistic utilization of gravity and mechanical energy: Rice grains fall naturally under gravity, reducing transportation energy consumption; the spring buffer system reduces vibration energy loss, resulting in overall energy consumption lower than traditional rigid vibration equipment;

[0059] Reduce raw material waste: Efficient dust removal and precise screening can reduce the probability of impurities and broken rice mixed with whole rice, thereby increasing the yield and economic value;

[0060] 6. This device takes mechanical structure innovation as its core and solves the problems of low efficiency, high damage and dust pollution of traditional equipment through three major technological breakthroughs: process integration, flexible vibration and dynamic dust removal. It is especially suitable for small and medium-sized rice processing enterprises and helps to achieve low-cost and high-cleanliness automated production upgrades. Attached Figure Description

[0068] 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.

[0069] Reference Figure 1 - Figure 3 An embodiment of this utility model provides an automated broken rice processing device for rice processing, comprising a base plate 1 and a feeding box 3. A screening box 2 is fixedly connected to the top of the base plate 1, and a feeding hopper 4 is provided at the top of the feeding box 3. A motor 5 is installed on the left outer wall of the feeding box 3. A rotating shaft 6 is fixedly connected to the drive end of the motor 5. Multiple diverting plates 7 are fixedly connected to the outer wall of the rotating shaft 6. A dust removal box 8 is fixedly connected to the bottom of the feeding box 3. A baffle plate 9 is provided on the rear side of the dust removal box 8. A dust removal assembly is provided on the front outer wall of the dust removal box 8. The dust removal assembly includes a motor 12 fixedly connected to the front outer wall of the dust removal box 8. A rotating rod 13 is fixedly connected to the drive end of the motor 12. A fan 14 is fixedly connected to the outer wall of the rotating rod 13. A collection box 15 is fixedly connected to the rear outer wall of the dust removal box 8. A filter screen 10 is fixedly connected to the rear side of the collection box 15.

[0070] Specifically, the base plate 1 is the basic support component of the entire device. The screening box 2 is fixedly connected to the top of the base plate 1, providing stable support for the rice screening operation. The feed hopper 4 is located at the top of the feed box 3, and the two are connected. The feed hopper 4 is used to guide the rice into the feed box 3. The motor 5 is installed on the left outer wall of the feed box 3, and the drive section of the motor 5 is fixedly connected to the rotating shaft 6. When the motor 5 starts, it can drive the rotating shaft 6 to rotate inside the feed box 3. Multiple diverting plates 7 are fixedly connected to the outer wall of the rotating shaft 6. When the rotating shaft 6 rotates, the diverting plates 7 rotate accordingly, which can divert the rice entering the feed box 3.

[0071] The bottom of the feed box 3 is fixedly connected to the dust collector 8. The rice diverted by the feed box 3 falls into the dust collector 8 for dust removal. The baffle plate 9 is set on the rear side of the dust collector 8 to block the rice and other materials, preventing them from overflowing directly to the rear. The dust removal assembly is installed on the front outer wall of the dust collector 8. Among them, the second motor 12 is fixedly connected to the front outer wall of the dust collector 8, and the drive end of the second motor 12 is fixedly connected to the rotating rod 13. The outer wall of the rotating rod 13 is fixedly connected to the fan 14. The second motor 12 drives the rotating rod 13 to rotate, which in turn drives the fan 14 to rotate, realizing the ventilation and dust removal functions in the dust collector 8. The collection box 15 is fixedly connected to the rear outer wall of the dust collector 8 to collect impurities separated during the dust removal process. The filter screen 10 is fixedly connected to the rear side of the collection box 15 to further filter impurities, prevent fine particles from escaping, and ensure air circulation.

[0072] Reference Figure 1 , Figure 4 and Figure 5 The top of the screening box 2 is fixedly connected to the bottom of the feed box 3. A motor 3 16 is installed on the left outer wall of the screening box 2. A rotating shaft 17 is fixedly connected to the drive end of the motor 3 16. Cams 18 are fixedly connected to the left and right ends of the rotating shaft 17. Sleeves 11 are fixedly connected to the four corners of the bottom of the inner wall of the screening box 2. A sliding rod 19 is slidably connected to the inner wall of the sleeve 11. A spring 20 is provided on the inner wall of the sleeve 11. The bottom end of the spring 20 is connected to the inner wall of the sleeve 11. The top end of the spring 20 is connected to the bottom end of the sliding rod 19. A discharge plate 21 is fixedly connected to the top end of the sliding rod 19. A connecting rod 22 is fixedly connected to the four corners of the top end of the discharge plate 21. A screening plate 23 is fixedly connected to the top end of the connecting rod 22. A first discharge port 24 is provided on the upper end of the front outer wall of the screening box 2. A second discharge port 25 is provided on the lower end of the front end of the screening box 2.

[0073] Specifically, the top of the screening box 2 is fixedly connected to the bottom of the feed box 3, so that the material coming out of the feed box 3 can smoothly enter the screening box 2 for the next screening process. The motor 3 16 is installed on the left outer wall of the screening box 2. As a power drive component, the motor 3 16 has a rotating shaft 17 fixedly connected to its drive end, which means that the motor 3 16 can drive the rotating shaft 17 to rotate after starting. The rotating shaft 17 is located inside the screening box 2 or in a related position, providing power for the subsequent screening action. The left and right ends of the rotating shaft 17 are fixedly connected to cams 18. When the rotating shaft 17 rotates under the drive of the motor 3 16, the cams 18 will make a circular motion. This motion characteristic of the cams 18 will be used to drive the related components to realize the screening action.

[0074] The sleeve 11 is fixedly connected to the four corners of the bottom of the inner wall of the screening box 2, providing support and limiting for the installation and movement of subsequent components. The outer wall of the sliding rod 19 is slidably connected to the inner wall of the sleeve 11, allowing the sliding rod 19 to reciprocate up and down within the sleeve 11. The spring 20 is located on the inner wall of the sleeve 11, with its bottom end connected to the inner wall of the sleeve 11 and its top end connected to the bottom end of the sliding rod 19. The spring 20 acts as a buffer and reset mechanism. When the sliding rod 19 moves up and down under external force, the spring 20 will be compressed or stretched accordingly. After the external force disappears, it can assist the sliding rod 19 to return to its initial position. The top end of the sliding rod 19 is fixedly connected to the discharge plate 21, so that the up and down movement of the sliding rod 19 can drive the discharge plate 21 to move synchronously. The discharge plate 21 serves to receive and transmit motion. The four corners of the top end of the discharge plate 21 are fixedly connected to the connecting rod 22, and the top end of the connecting rod 22 is fixedly connected to the screening plate 23. The movement of 21 is transmitted through the connecting rod 22, which drives the screening plate 23 to move up and down reciprocally, thereby realizing the screening operation of the material falling on the screening plate 23. The upper end of the front outer wall of the screening box 2 is provided with a first discharge port 24, which is used to discharge the material that meets certain specifications after screening, such as larger particles. Its position is coordinated with the screening action of the screening plate 23 to ensure that the qualified material can be discharged smoothly from here. The lower end of the front end of the screening box 2 is provided with a second discharge port 25, which is used to discharge the material that does not meet the relevant specifications after screening, such as smaller particles. Similarly, according to the screening situation of the screening plate 23, the corresponding material can be discharged through this discharge port to complete the entire screening and discharge process.

[0075] Working principle: Rice enters the feeding box 3 through the feeding hopper 4. After the motor 1 5 starts, it drives the rotating shaft 6 to rotate, which drives the diversion plate 7 on the outer wall to rotate synchronously. The rotating diversion plate 7 disperses the concentrated falling rice to all sides, avoiding blockage at the bottom of the feeding box 3 and ensuring that the material enters the subsequent processing stage evenly. The dispersed rice falls from the bottom of the feeding box 3 into the dust removal box 8. The motor 2 12 drives the rotating rod 13 to drive the fan 14 to rotate at high speed, generating airflow. The airflow sucks up light impurities such as dust and broken shells in the rice and puts them into the collection box 15. The filter screen 10 ensures air circulation between the collection box 15 and the dust removal box 8 and prevents dust from overflowing. The heavier rice grains continue to fall under the action of gravity. The baffle plate 9 on the rear side of the dust removal box 8 prevents the rice grains from overflowing directly to the rear, ensuring that the material is fully dusted in the box.

[0076] After dust removal, the rice enters the screening box 2. The motor 16 drives the rotating shaft 17 to rotate, which in turn drives the cams 18 at both ends to make circular motion. The cams 18 periodically squeeze the sliding rod 19, causing it to slide up and down inside the sleeve 11. The spring 20 provides buffering and restoring force to reduce vibration and impact. The sliding rod 19 drives the screening plate 23 to make high-frequency reciprocating vibration through the discharge plate 21 and the connecting rod 22. The rice grains jump on the screening plate 23. Large particles remain on the screen surface, while small particles and broken rice fall through the screen holes onto the discharge plate 21. The large rice grains after screening move towards the front of the screening box 2 with the vibration and are discharged from the first discharge port 24 at the top, serving as finished products or raw materials for further processing. Broken rice and fine impurities that pass through the screen holes fall onto the discharge plate 21 and are discharged from the second discharge port 25 at the bottom, realizing automated classification and collection.

[0077] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
