[0002] In the field of agricultural production, with the improvement of people's living standards, the requirements for the quality of rice are also increasing day by day. Germinated brown rice has received extensive attention due to its rich nutritional components. At present, there are obvious deficiencies in the bran removal link of germinated brown rice milling machines on the market. On the one hand, existing rice milling machines lack an effective real-time detection mechanism and cannot detect problems in time when the bran removal effect is poor. For example, during the rice milling process, due to factors such as differences in rough rice varieties and wear of equipment components, if the bran removal is incomplete, or excessive milling causes an increase in the broken rice rate, the equipment cannot perceive these changes in time and cannot adjust the rice milling parameters accordingly. On the other hand, the discharging structure of traditional rice milling machines cannot meet the needs of quality inspection of the finished rice, and it is difficult to ensure that the produced rice always meets high-quality standards. This has affected the rice milling efficiency and product quality to a certain extent and cannot meet the needs of modern agricultural production and the market. Summary of the Invention

[0040] The present invention provides a discharge assembly 100 and a rice milling device 1000 having the same. Please refer to Figures 1 to 10 , the rice milling device 1000 provided by the present invention includes a frame 200, a feeding assembly 400, a rice milling assembly 300, and a discharge assembly 100. Among them, the frame 200 has a feeding station 201, a feeding station 202, and a discharging station 203 arranged in sequence from front to back, providing a stable support and a reasonable layout space for the entire rice milling production process. The feeding assembly 400 is arranged at the feeding station 201 and is used to convey raw materials to the inlet end of the rice milling channel 303. The rice milling assembly 300 is at the feeding station 202 and is used to convey the material from back to front and perform rice milling treatment during the conveying process. The discharge assembly 100 is arranged at the discharging station 203 to realize the discharging and collection of the material after rice milling and bran removal.
[0041] In a preferred embodiment, the rice milling assembly 300 includes a first conveyor belt 301 and a second conveyor belt 302 that extend in the front-rear direction respectively. The first conveyor belt 301 and the second conveyor belt 302 are arranged at intervals in the up-down direction in sequence, forming a rice milling channel 303 for milling paddy rice. The discharging assembly 100 is arranged at the blanking station 203 to collect and discharge the milled finished rice.
[0042] In this embodiment, the material structure of the frame 200 can be optimized according to the usage environment and requirements of the equipment, and different materials and surface treatment methods can be selected for the conveyor belts of the rice milling assembly 300. Specifically, please refer to Figure 8 , the surface of the second conveyor belt 302 is made of abrasive belt material, and there is a rigid support plate at the bottom which can be regarded as rigid. The surface of the first conveyor belt 301 is made of abrasive belt material, and there is a rubber support with moderate elasticity on the upper part which can be regarded as flexible. The paddy rice is milled during the friction process under the combined action of the two. In addition, some protrusions or grooves can be provided on the conveyor belt to further optimize the movement state of the material on the conveyor belt and improve the rice milling quality. Preferably, in this embodiment, an adjusting mechanism 304 is provided between the first conveyor belt 301 and the second conveyor belt 302, which can adjust the height of the rice milling channel 303, so as to realize the adjustment of the rice milling effect and the conveying speed.
[0043] Preferably, as Figure 10 shown, the rice milling assembly 300 further includes a bran removing mechanism 70 arranged on the upper side of the first conveyor belt 301 and the lower side of the second conveyor belt 302. The bran removing mechanism 70 includes a brush roller 71, an air knife 72 and a dust suction device 73 arranged in sequence along the conveying direction. Specifically, the design of the brush roller 71 can be more diversified. According to different rice milling processes and paddy rice varieties, bristles with different hardness, density and length can be selected. For paddy rice with a harder texture, bristles with higher hardness and density can be used to enhance the bran removing effect; for paddy rice that is easily broken, softer and moderately dense bristles are selected to avoid damaging the rice grains. At the same time, the rotation speed of the brush roller 71 can also be adjusted by a frequency conversion motor, and the rotation speed can be adjusted according to the actual bran removing requirements to achieve the best bran removing efficiency. The parameters of the air knife 72 can also be optimized. The shape and angle of the air outlet of the air knife 72 can be adjusted. In terms of the dust suction device 73, devices with different suction and filtration precision can be selected. For the case of more bran, a dust suction device 73 with a larger suction is selected to ensure that all the blown-off bran can be collected in time. At the same time, high-precision filter materials, such as HEPA filters, are used, which can effectively filter the tiny particles in the air and prevent the bran from escaping into the working environment again, keeping the production environment clean.
[0044] In this embodiment, the design of the bran removal mechanism 70 significantly improves the quality of the finished rice. By effectively removing the bran, the finished rice is made more pure and beautiful, meeting the market requirements for high-quality rice. Secondly, it reduces the pollution of the production environment by the bran, improves the working environment, and safeguards the health of the operators. In addition, it avoids the accumulation of bran inside the equipment, reduces the risk of equipment failure, extends the service life of the equipment, reduces the equipment maintenance cost, helps to improve the continuity and stability of production, and thus improves the production efficiency.
[0045] Further, please continue to refer to Figures 7 to 9 , the feeding assembly 400 includes a material leveling mechanism 40 and a wedge-shaped inlet mechanism 50 arranged in sequence from front to back. The function of the material leveling mechanism 40 is to make the paddy rice fall evenly on the second conveyor belt 302, providing a stable material flow for the subsequent rice milling process. Specifically, the material leveling mechanism 40 includes a feed hopper and leveling rods. The leveling rods are arranged at the outlet of the feed hopper and make the paddy rice fall evenly on the second conveyor belt 302 during rotation. The second conveyor belt 302 drives the paddy rice forward through friction until it enters the rice milling channel 303 composed of two conveyor belts.
[0046] As Figure 7 and Figure 9 shown, the wedge-shaped inlet mechanism 50 is used to flatten the paddy rice so as to facilitate its entry into the rice milling channel 303, effectively alleviating the blockage phenomenon at the inlet of the rice milling chamber. In this embodiment, the wedge-shaped inlet has a structure with adjustable height. Specifically, the second conveyor belt 302 extends forward to the feeding station 201. The wedge-shaped inlet mechanism 50 includes a hinge 51 rotatably and adjustably mounted on the upper side of the second conveyor belt 302 at the feeding station 201. The hinge 51 is located behind the rice milling channel 303 and is arranged to slope downward from back to front and downward. In this embodiment, by adjusting the rotation of the hinge 51, the size and angle of the inlet can be adjusted according to the flow rate and characteristics of the paddy rice, effectively alleviating the blockage phenomenon at the inlet of the rice milling chamber.
[0047] Preferably, a second vision detection component 60 is provided above the material leveling mechanism 40. The second vision detection component 60 is used to obtain the material images to be loaded. By analyzing these images, the quality status of the paddy rice, such as impurity content, grain plumpness, etc., can be understood in advance, so as to adaptively adjust the processing parameters (such as the feeding speed, the size of the rice milling channel 303, and the conveying speeds of the two conveying belts, etc.). Specifically, the second vision detection component 60 is started before or during the operation of the material leveling mechanism 40. Its optical lens collects the reflected light signals of the material to be loaded, converts them into electrical signals, and then forms digital image data through analog-to-digital conversion. These data are transmitted to the connected image processing unit, and the image processing unit uses a preset algorithm to extract and analyze the material characteristics in the image. For example, impurities and paddy rice are distinguished through a color recognition algorithm, and the plumpness and integrity of the grains are judged through a shape analysis algorithm.
[0048] In this way, by detecting the material quality in advance, the rice milling equipment 1000 can set the processing parameters more accurately according to this information. For example, if it is detected that there are more impurities in the paddy rice, the working intensity of the rice milling component 300 can be appropriately increased. If it is found that the paddy rice grains are generally small, the rice milling force can be reduced to avoid an increase in the broken rice rate caused by excessive milling. This greatly improves the quality and efficiency of rice milling, and reduces the energy waste and material loss caused by unreasonable parameters.
[0049] In an embodiment, please refer to Figures 1 to 3 , the discharge assembly 100 includes a discharge mechanism 10 and a first detection mechanism 20. The discharge mechanism 10 is provided with a feed inlet 11. The discharge mechanism 10 forms a first channel 12 and a second channel 13. The feed ends of the first channel 12 and the second channel 13 are respectively communicated with the feed inlet 11. The discharge end of the first channel 12 leads to the first working station 101, and the discharge end of the second channel 13 can lead to the second working station 102. The first detection mechanism 20 includes a first detection component 21, a first driving device 22, and a conveying member 23 extending in the front-rear direction. The first detection component 21 is provided at the front end of the conveying member 23. The rear end of the conveying member 23 faces the first working station 101. The conveying member 23 forms a second working station 102 between its front end and rear end. The first driving device 22 is drivingly connected to the conveying member 23 to drive the conveying member 23 to move in the front-rear direction.
[0050] In this embodiment, after the material enters the discharging mechanism 10 from the feeding port 11, a part of the material is directly transported to the first station 101 through the first channel 12 for subsequent conventional processes such as packaging and storage. Another part of the material enters the second channel 13 and reaches the second station 102. At this time, the first driving device 22 is started to drive the conveying member 23 to move backward, and the material located at the second station 102 is transported below the first detection component 21. The first detection component 21 detects the material to obtain relevant data information. In this way, while ensuring production efficiency, problems in the production process, such as quality fluctuations of the material and poor processing effects, can be detected in a timely manner by detecting some of the materials. Furthermore, the upstream processing parameters can be adjusted according to the detection results to ensure the stability of product quality and improve the overall production efficiency.
[0051] The type of the first detection component 21 can be selected in a variety of ways. In addition to the conventional visual detection component, a weight sensor can also be integrated to measure the weight of the material while obtaining the image of the material, so as to more comprehensively understand the material information. Preferably, the first detection component 21 adopts a first visual detection device arranged above the front end of the conveying member 23. This first visual detection device uses the principle of optical imaging and can clearly obtain the image information of the material carried at the front end of the conveying member 23. By analyzing these images, the appearance characteristics of the material, such as the integrity of the particles, the smoothness of the surface, and the uniformity of the color, can be judged, and then the quality and processing effect of the material can be evaluated.
[0052] Furthermore, the first detection mechanism 20 further includes a shielding member 24 mounted on the conveying member 23. The shielding member 24 is arranged between the front end of the conveying member 23 and the second station 102, and a material passing gap 241 is defined between the shielding member 24 and the upper side of the conveying member 23. Preferably, the installation position of the shielding member 24 is adjustable, so as to adjust the size of the material passing gap 241 as needed. In this embodiment, when the material moves on the conveying member 23 towards the second station 102, the shielding member 24 restricts the movement range of the material, and only the material passing through the material passing gap 241 can reach the second station 102 for detection. This ensures the distribution state of the material, facilitates the first detection component 21 to obtain the material image, and reduces the detection error caused by the difference in the amount and distribution of the material. In this way, the accuracy and repeatability of the detection are improved, and the detection data is more stable and reliable. Based on these accurate data, the parameter adjustment in the production process is more accurate, the product quality can be better controlled, and the production loss caused by unstable quality can be reduced.
[0053] On the basis of the above embodiment, please continue to refer to Figure 5 and Figure 6The discharge assembly 100 also includes a switching mechanism 30, which includes a second drive device 31 and a guide member 32 movably installed at the second channel 13. The second drive device 31 drives the connecting guide member 32 to switch the guide member 32 between the first working position and the second working position. When the guide member 32 is in the first working position, the discharge end of the second channel 13 is connected to the first workstation 101. When the guide member 32 is in the second working position, the discharge end of the second channel 13 is connected to the second workstation 102.
[0054] In this embodiment, the second drive device 31 drives the guide member 32 to move according to demand. Under the action of the driving force, the guide member 32 switches between the first working position and the second working position, changing the conduction direction of the discharge end of the second channel 13. For example, when it is necessary to guide the material to the first workstation 101, the second drive device 31 drives the guide member 32 to switch to the first working position, so that the discharge end of the second channel 13 is connected to the first workstation 101. When it is necessary to guide the material to the second workstation 102 for inspection, the guide member 32 switches to the second working position, so that the discharge end of the second channel 13 is connected to the second workstation 102. This flexible switching design enables the switching mechanism 30 to quickly and accurately adjust the flow direction of the material according to different production processes and quality inspection requirements, and to inspect the discharged material when necessary. In this way, by accurately controlling the flow direction of the material, it is possible to better control the quality of the product and meet diverse production needs.
[0055] Specifically, the guide member 32 is a material guide plate rotatably mounted on the discharging mechanism 10, and the second driving device 31 includes a second motor 311 and a clutch device 312 arranged on the discharging mechanism 10. The second motor 311 can be clutched to the material guide plate shaft through the clutch device 312 to drive the material guide plate to periodically rotate back and forth between the first working position and the second working position.
[0056] In this embodiment, when the guide plate needs to rotate, the second motor 311 is powered on and started, and the motor shaft begins to rotate. The clutch device 312 is engaged under the control of the control system, and the power of the second motor 311 is transmitted to the rotating shaft of the guide plate, so that the guide plate begins to rotate. In this way, by controlling the power-on time of the second motor 311 and the engagement time of the clutch device 312, the rotation angle and the stop position of the guide plate can be accurately controlled to achieve accurate conduction between the discharge end of the second channel 13 and the first station 101 or the second station 102. The beneficial effect of this structural design is that it has a simple structure, is easy to control, and can reliably achieve periodic switching of the discharge direction of the second channel 13. Compared with other complex switching structures, this design reduces the manufacturing cost and maintenance difficulty of the equipment, improves the operating stability and reliability of the equipment, and ensures the smooth progress of the production process.
[0057] Preferably, the discharging mechanism 10 further includes a discharging member 40. The material guiding plate, the conveying member 23, and the discharging member 40 are arranged in sequence from top to bottom. The upper side of the discharging member 40 is provided with an open mouth 41. The front end of the conveying member 23 is located behind the material guiding plate, and the rear end is located directly above the open mouth 41. During the stroke of the material guiding plate switching from the first working position to the second working position, the material guiding plate flips backward and upward to guide the second channel 13 to the second working station 102. During the stroke of the material guiding plate switching from the second working position to the first working position, the material guiding plate flips forward and downward to guide the open mouth 41.
[0058] In this embodiment, when the material guiding plate is in the first working position, the discharging end of the second channel 13 guides to the first working station 101. After the material flows out of the second channel 13, it directly enters the first working station 101 for subsequent processing. When it is necessary to guide the material to the second working station 102 for detection, the material guiding plate flips backward and upward under the action of the second driving device 31, so that the discharging end of the second channel 13 guides to the second working station 102. After the material flows out of the second channel 13, it falls on the front end of the conveying member 23, and then is transported forward by the conveying member 23 to be detected under the first detection component 21. After the detection is completed, the conveying member 23 transports the material backward, so that the material falls back into the open mouth 41 of the discharging member 40. When the material guiding plate switches back from the second working position to the first working position, the material guiding plate flips forward and downward to guide the material to the open mouth 41 of the discharging member 40. After the material falls into the discharging member 40, the discharging process is completed.
[0059] When the rice milling equipment 1000 is working, when the paddy enters the material leveling mechanism 40 through the feeding assembly 400, the surface reflected light signal is collected in real time by the second vision detection component 60 and converted into digital image data, which is synchronously transmitted to the image processing unit. Based on the impurity recognition algorithm of the color space model and the multi-dimensional shape feature extraction algorithm, this unit intelligently discriminates the type of paddy and generates the characteristic parameters of the paddy variety. The control system matches the characteristic parameters with the pre-stored database: if there is a processing strategy record corresponding to the paddy type in the database, the optimized processing parameter combination of this variety is automatically retrieved, including the coordinated speed ratio of the first conveyor belt 301 and the second conveyor belt 302, the gap height threshold of the rice milling channel 303, and the rotation speed curve of the brush roller 71 in the bran removing mechanism 70; if no matching item is retrieved, the default processing strategy preset by the system is enabled to ensure the stability of the basic processing parameters. During the execution process, the material leveling mechanism 40 dynamically adjusts the distribution density of the paddy through the leveling rod, so as to form a uniform material layer on the surface of the second conveyor belt 302.
[0060] Next, the brown rice is leveled by the wedge-shaped inlet mechanism 50 and then enters the rice milling channel 303. It is milled under the frictional action of the first conveyor belt 301 and the second conveyor belt 302. The height of the rice milling channel 303 can be adjusted by the adjusting mechanism 304 to control the rice milling effect and speed. During the rice milling process, the brush roller 71, the air knife 72 and the dust suction device 73 of the bran removing mechanism 70 cooperate to remove bran.
[0061] In the discharging stage of the rice milling equipment 1000, after the materials processed by the rice milling channel 303 and the bran removing mechanism 70 enter the discharging assembly 100, the control system executes path allocation according to the preset shunt logic: the regular materials are conveyed to the first station 101 through the first channel 12 for packaging, while the quality inspection samples are switched to the second channel 13 by the second driving device 31 of the switching mechanism 30. Specifically, the second motor 311 combines the linkage control of the clutch device 312 to accurately position the guide plate at the receiving position of the second station 102. Subsequently, the conveyor 23 driven by the first driving device 22 sends the samples to the detection area of the first detection component 21. This detection component obtains the surface characteristics of the materials based on high-resolution optical imaging technology, and through the image processing unit combined with the edge gradient detection algorithm and the gray-level co-occurrence matrix texture analysis algorithm, quantitatively evaluates the core quality indicators such as the broken rice rate and the degree of retained bran.
[0062] When the detection data exceeds the preset threshold range, the control system triggers a dynamic correction mechanism: First, based on the current rice milling quality defect characteristics (such as excessive broken rice rate or insufficient bran layer peeling), the pressure parameters of the rice milling channel 303, the rotational speed gradient of the brush roller 71, and the air flow intensity combination of the air knife 72 are adjusted in real time; Second, the optimized processing parameter combination is used as a new version of the strategy and is synchronously updated to the corresponding processing strategy file of this brown rice variety in the database to form a data closed-loop feedback. Finally, the updated strategy parameters are immediately called to execute the rice milling process to ensure that the subsequent processing of the same batch of materials is adapted to the quality requirements in real time. During this process, the control system realizes the dynamic iteration of the processing strategy through a multi-dimensional quality evaluation model and a parameter combination self-optimization algorithm, and relies on the data synchronization mechanism to ensure the consistency of the strategy version, thereby improving the adaptive ability of the equipment to the fluctuations of raw material characteristics and maintaining the stable output of the quality of the milled rice.

Any equivalent structures made by using the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present invention.
