Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to silo components, grain processing equipment and control methods. Background Technology

[0002] A rice milling machine is a grain processing device used to dehull paddy and process it into fresh rice. The rice milling machine mainly consists of a main body and a paddy silo (referred to as "silo" or "silo body"). The paddy silo is located inside the main body and is used for temporary storage of paddy to be processed. A discharge port that can be opened / closed is located at the bottom of the paddy silo. The paddy inside the silo can be conveyed to the rice milling silo through the discharge port for dehulling, grinding, and other processing.

[0003] In related technologies, the amount of rice output from the rice bin outlet each time (i.e., the amount of rice discharged) often needs to be manually controlled, which is not only time-consuming and labor-intensive, but also has a large error in the amount of rice discharged, making it difficult to meet the needs of users and causing inconvenience to users. Summary of the Invention

[0004] Therefore, it is necessary to provide a silo component, a grain processing device, and a control method to address the problems of time-consuming, labor-intensive, and error-prone control of the rice output from the rice milling device's silo outlet.

[0005] A silo assembly for use in a grain processing apparatus, the silo assembly comprising:

[0006] The hopper has a storage chamber inside, and a first discharge port is located at the bottom of the storage chamber. The inner wall of the storage chamber includes a first-level inner wall surface, which is located close to the first discharge port. The angle between the first-level inner wall surface and a first direction is α, and the first direction is perpendicular to the discharge direction.

[0007] An opening and closing mechanism is provided in the chamber body, and the opening and closing mechanism is used to open / close the first discharge port;

[0008] Wherein, the area of ​​the first discharge port is S, the area S satisfies a preset area range, and the included angle α satisfies a preset angle range. The opening and closing mechanism opens the first discharge port according to the received user selection signal, so that the total discharge amount of the first discharge port corresponds to the user selection signal.

[0009] The aforementioned storage assembly includes a storage body and an opening / closing mechanism. The storage body has a storage chamber with a first discharge port at its bottom. The area S of the first discharge port meets a preset area range, and the angle α between the first-stage inner wall surface of the storage chamber and the first direction meets a preset angle range. Based on a received user selection signal, the opening / closing mechanism opens the first discharge port so that the total discharge volume corresponds to the user selection signal. In this application, when the area S of the first discharge port meets the preset area range and the angle α between the first-stage inner wall surface and the first direction meets the preset angle range, the grain in the storage chamber can fall and discharge quickly, accelerating the discharge speed, which helps to shorten the discharge time, improve grain processing efficiency, and thus achieve energy saving. Furthermore, since the user selection signal corresponds to the user's desired discharge volume, the opening / closing mechanism controls the opening of the first discharge port based on the received user selection signal, ensuring that the total discharge volume of the first discharge port is basically consistent with the user's desired discharge volume. This achieves automatic control of the rice output, saving time and effort, meeting user needs, and bringing great convenience to users.

[0010] In one embodiment of this application, the user selection signal includes a grain characteristic signal and a desired quantity signal. Based on the grain characteristic signal, the opening and closing mechanism controls the single opening time of the first discharge port to be T1, and based on the desired quantity signal, the opening and closing mechanism controls the number of times the first discharge port is opened to be N.

[0011] The aforementioned silo components utilize user selection signals including grain characteristic signals and desired quantity signals. The grain characteristic signals characterize the grain's properties; different grain characteristics result in different discharge rates (discharge resistance). The single-opening time T1 of the first discharge port can be determined based on the grain characteristic signals to precisely control the discharge volume per opening (i.e., single-time discharge), improving discharge accuracy and reducing errors. The discharge volume per single opening of the first discharge port is also one unit. The number of times the first discharge port opens, N, is determined based on the desired quantity signal. When controlling the opening of the first discharge port, the single-opening time is set to T1, and the number of openings is set to N. The total discharge volume after N openings corresponds to the user selection signal, meeting user needs and ensuring accurate control of the discharge volume.

[0012] In one embodiment of this application, the grain feature signal includes a grain type signal or a grain shape signal.

[0013] The aforementioned silo components utilize grain characteristic signals, including grain type signals or grain shape signals. Since different types of grains vary in weight, volume, shape, and moisture content, the discharge rate (discharge resistance) differs for different grain types when the first discharge port is open. The single opening time T1 of the first discharge port can be determined based on the grain type to adjust the discharge volume within that time, thereby improving discharge control accuracy. Similarly, the single opening time T1 of the first discharge port can be directly determined based on the grain shape signal to adjust the discharge volume within that time, simplifying the control logic while maintaining discharge volume control accuracy.

[0014] In one embodiment of this application, the discharge amount from the first discharge port is 180g-200g during the single opening time T1.

[0015] The above-mentioned silo assembly has a discharge capacity of 180g-200g from the first discharge port within a single opening time T1. This ensures the grain processing effect (i.e., grinding effect) while shortening the grain processing time (grinding time), achieving a balance between grain processing time and processing effect, and meeting the daily needs of users.

[0016] In one embodiment of this application, the user selection signal includes a desired grain volume signal, and the opening and closing mechanism opens the first discharge port according to the desired grain volume signal and continues for a corresponding preset time T2.

[0017] The aforementioned silo components include a user selection signal for the required grain quantity, which represents the user's desired output quantity. Based on the user's desired output quantity, the first discharge port is controlled to remain open for a preset time T2, enabling continuous grain output. This simplifies the control logic, improves the accuracy of the output quantity, reduces output errors, meets the user's needs, and brings great convenience to the user.

[0018] In one embodiment of this application, the preset time T2 is in the range of 3s-15s.

[0019] The preset time T2 of the aforementioned storage unit is between 3s and 15s. Within this range, it can meet the user's usual grain needs without making the user wait for a long time.

[0020] In one embodiment of this application, the inner wall of the storage cavity further includes a second-level inner wall surface, which is connected to the end of the first-level inner wall surface away from the first discharge port, and the first-level inner wall surface and the second-level inner wall surface are set at an angle.

[0021] The aforementioned hopper assembly includes a second-level inner wall surface within the storage chamber. This second-level inner wall surface connects to the end of the first-level inner wall surface furthest from the first discharge port. The first and second-level inner wall surfaces are angled, meaning they are not on the same plane at the same location, creating a multi-level structure within the storage chamber. Furthermore, the angle between the first and second-level inner wall surfaces can be adjusted as needed. For example, the second-level inner wall surface can be tilted outwards relative to the first-level inner wall surface, increasing the internal capacity of the storage chamber; or it can be tilted inwards relative to the first-level inner wall surface, allowing for faster material discharge from the first discharge port. This aligns with the design requirements of different products, enabling flexible and diverse product structure designs.

[0022] In one embodiment of this application, the angle between the second-level inner wall surface and the first direction is β, and the value of the angle β is in the range of 0° < β < α.

[0023] In the aforementioned silo assembly, the angle β between the second-stage inner wall surface and the first direction satisfies 0° < β < α, meaning the slope of the second-stage inner wall surface is less than the slope of the first-stage inner wall surface. The second-stage inner wall surface is gentler than the first-stage inner wall surface, making the upper part of the storage cavity have an outward expansion structure, thus increasing the volume of the storage cavity. Moreover, the second-stage inner wall surface is located far away from the first discharge port, so it will not affect the discharge speed of the first discharge port.

[0024] In one embodiment of this application, the preset area range is S≥30mm. 2 And / or the preset angle range is α≥30°.

[0025] The aforementioned compartment components have a preset area range of S≥30mm². 2 This ensures that the grains do not clog the first discharge port when falling from it, guaranteeing a smooth descent. In one embodiment, the preset angle range is α ≥ 30° to ensure the grains can smoothly slide into the first discharge port. In another embodiment, the preset area range is S ≥ 30mm. 2 The preset angle range is α≥30°. By coordinating the material discharge slope of the inner wall of the storage chamber and the area of ​​the first discharge port, it can meet the work efficiency requirements of the fully automatic rice milling machine in the rice feeding stage in a household setting. Compared with the existing technology that requires manual rice addition, it can ensure that the first discharge port does not get blocked, and the time consumption is short, making the work more efficient and intelligent.

[0026] In one embodiment of this application, the interior of the silo body further includes an installation cavity, which is separated from the storage cavity, and the opening and closing mechanism is detachably disposed within the installation cavity.

[0027] In the aforementioned silo assembly, the storage chamber and installation chamber inside the silo are separated and do not affect each other. The storage chamber is used to store the grains to be processed, and the opening and closing mechanism is located in the installation chamber. This silo assembly's opening and closing mechanism is located inside the silo body, thus not occupying external space, making the silo assembly compact and aesthetically pleasing, facilitating installation. Furthermore, the connection between the opening and closing mechanism and the silo body is also located inside the silo body, preventing contact with external forces and ensuring a secure connection. This significantly improves structural reliability, ensures the normal operation of the grain processing device, and provides excellent sealing at the connection point, preventing leakage of grain particles or flour and maintaining the cleanliness of the entire machine.

[0028] In one embodiment of this application, the opening and closing mechanism includes a baffle having a first position for opening the first discharge port and a second position for closing the first discharge port, the baffle being controllably reciprocating between the first position and the second position.

[0029] The opening and closing mechanism of the aforementioned hopper assembly includes a baffle that can be controllably moved back and forth between a first position and a second position to control the opening and closing of the first discharge port. This opening and closing mechanism has a simplified structure, simple control logic, and high reliability.

[0030] In one embodiment of this application, the silo further includes a bottom cover, which is detachably connected to the bottom of the silo. The bottom cover has a second discharge port corresponding to the first discharge port, and the baffle is movably disposed between the storage cavity and the bottom cover.

[0031] The aforementioned silo assembly includes a bottom cover, which is detachably connected to the bottom of the silo body. This allows for the installation of opening and closing mechanisms within the silo, facilitating installation and operation, providing reliable protection for these mechanisms, and forming a unified structure for easy relocation. Furthermore, a first and second discharge port are correspondingly positioned, and a baffle is movably located between the storage chamber and the bottom cover, facilitating the opening and closing control of the first discharge port.

[0032] In one embodiment of this application, the opening and closing mechanism further includes a mounting plate disposed between the storage cavity and the bottom cover, the baffle being movably disposed on the mounting plate, and the mounting plate having a third discharge port corresponding to the first discharge port.

[0033] The opening and closing mechanism of the aforementioned silo assembly also includes a mounting plate. The mounting plate has a third discharge port that is corresponding to the first discharge port. This facilitates the installation of the opening and closing mechanism and does not affect the grain output of the silo assembly. It achieves the coordinated cooperation of the various structural components, making the silo assembly structure compact, reasonable and reliable.

[0034] In one embodiment of this application, the size of the third discharge port is larger than the size of the first discharge port, and the first discharge port is adapted to be inserted into the third discharge port.

[0035] In the aforementioned hopper assembly, the first discharge port is adapted to be inserted into the third discharge port, so as to facilitate the positioning of the third discharge port with the first discharge port, simplify the structural fit, and improve the reliability of the structure.

[0036] In one embodiment of this application, the opening and closing mechanism further includes a reinforcing plate disposed in a portion of the area between the baffle and the mounting plate, the reinforcing plate serving to support the mounting plate.

[0037] The aforementioned compartment assembly, including the opening and closing mechanism, also includes a reinforcing plate. The reinforcing plate is used to support the mounting plate. Since the mounting plate is mostly made of plastic, the reinforcing plate can enhance the structural strength of the mounting plate and improve its structural reliability. Moreover, the reinforcing plate can be made of metal, which can reduce the resistance when the baffle moves relative to each other, making the reciprocating movement of the baffle smoother.

[0038] In one embodiment of this application, the baffle has a communication port. When the baffle is in the first position, the communication port is connected to the first discharge port. When the baffle is in the second position, the communication port is misaligned with the first discharge port, and the first discharge port is blocked by the baffle.

[0039] In the aforementioned hopper assembly, the baffle has a connecting port. This connecting port reciprocates between a first position and a second position. When the baffle is in the first position, the connecting port is connected to the first discharge port. When the baffle is in the second position, the connecting port is misaligned with the first discharge port, and the first discharge port is blocked by the baffle. This ingenious opening and closing mechanism design facilitates structural layout and improves the response speed of the opening and closing mechanism, thereby increasing the speed at which the first discharge port is opened or closed.

[0040] In one embodiment of this application, the opening and closing mechanism further includes a positioning detection component, which is used to detect whether the baffle has moved to the first position and whether it has moved to the second position.

[0041] The opening and closing mechanism of the aforementioned compartment assembly also includes a positioning detection component. The positioning detection component is used to detect whether the baffle has moved into position, that is, whether the baffle has moved to the first position or the second position. When the baffle reaches the first position or the second position, the drive to continue moving the baffle is stopped, thereby improving the reliability of the structural control.

[0042] In one embodiment of this application, the opening and closing mechanism further includes a push rod, one end of which is connected to the baffle near the first discharge port; the positioning detection component includes a detection component, a first trigger, and a second trigger. The detection component is disposed on the mounting plate, and the first trigger and the second trigger are disposed at intervals on the push rod. When the first trigger contacts the detection component, the baffle moves to the first position; when the second trigger contacts the detection component, the baffle moves to the second position.

[0043] The aforementioned compartment assembly includes a positioning detection component comprising a detection element, a first trigger, and a second trigger. The first and second triggers move synchronously with the push rod and the baffle. When the first trigger contacts the detection element, the baffle moves to a first position; when the second trigger contacts the detection element, the baffle moves to a second position. This positioning detection component offers a simple detection method and high accuracy.

[0044] A grain processing apparatus includes: a housing, the aforementioned hopper assembly, and a control module. The hopper assembly is detachably or fixedly connected to the top of the housing. The control module is electrically connected to the opening and closing mechanism. The control module controls the opening and closing mechanism to open the first discharge port according to a received user selection signal, so that the total discharge volume of the first discharge port corresponds to the user selection signal.

[0045] The above-mentioned grain processing apparatus, including the above-mentioned silo assembly, has the same beneficial effects as the silo assembly, which will not be elaborated here.

[0046] In one embodiment of this application, the grain processing apparatus is a rice milling machine.

[0047] The aforementioned grain processing device is specifically a rice milling machine, used to process paddy rice, making it convenient for home use.

[0048] A control method, executed by the aforementioned grain processing apparatus, the control method comprising:

[0049] The first discharge port is opened according to the user selection signal, so that the total discharge volume of the first discharge port corresponds to the user selection signal.

[0050] The above-mentioned control method is executed by the above-mentioned grain processing device and has the same beneficial effects as the grain processing device, which will not be elaborated here.

[0051] In one embodiment of this application, the user selection signal includes a grain characteristic signal and a desired quantity signal; the control method includes:

[0052] The single opening time T1 of the first discharge port is determined based on the grain characteristic signal;

[0053] The number of times N that the first discharge port is opened is determined based on the required quantity signal;

[0054] According to the single opening time T1 and the number of openings N, the first discharge port is controlled to open, and the grain is discharged.

[0055] After the first discharge port is opened a certain number of times (N), the first discharge port is controlled to close.

[0056] The above control method can determine the single opening time T1 of the first discharge port based on the grain characteristic signal, and determine the number of times the first discharge port is opened N based on the required number of portions signal, so that the total discharge of the first discharge port corresponds to the user selection signal, meets the user's required discharge amount, achieves precise control of the discharge amount, has small discharge error, and brings great convenience to the user.

[0057] In one embodiment of this application, the step of controlling the opening of the first discharge port and discharging grain according to the single opening time T1 and the number of openings N includes:

[0058] Each time the first discharge port is opened, the discharged grain is processed. After processing is completed, the first discharge port is opened again, until the number of times the first discharge port is opened is N.

[0059] The above control method processes the grain after each discharge, and then discharges again after processing is completed. This ensures that the amount of grain processed each time is neither too much nor too little, achieving a balance between processing time and processing effect, simplifying control logic, and improving user experience.

[0060] In one embodiment of this application, the user selection signal includes a desired valley quantity signal; the control method includes:

[0061] Based on the required output amount corresponding to the required valley volume signal, determine the preset time T2 for opening the first discharge port and continuing to do so.

[0062] Control the opening of the first discharge port to discharge grain;

[0063] After the first discharge port is opened and remains open for the preset time T2, the first discharge port is controlled to close.

[0064] The above control method can determine the preset time T2 for continuously opening the first discharge port based on the user's required discharge amount corresponding to the required valley volume signal, and then control the first discharge port to open for the preset time T2, so that the first discharge port can continuously discharge material and the total discharge amount can meet the user's needs. This achieves precise control of the discharge amount, with high accuracy and small discharge error, bringing great convenience to the user. Attached Figure Description

[0096] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0097] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0098] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0099] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0100] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0101] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0102] In related technologies, rice milling machines have a discharge port at the bottom of the rice hopper, equipped with an opening and closing mechanism to control the opening and closing of the discharge port. Before using the rice milling machine, the discharge port needs to be opened to feed paddy into the rice milling hopper. However, currently, the amount of paddy discharged from the rice milling machine's discharge port is mainly controlled manually; that is, the amount of paddy needed is added to the rice hopper, and then the paddy in the rice hopper is transported to the rice milling hopper. This method of controlling the amount of paddy discharged is time-consuming and labor-intensive, and is greatly affected by human factors, often resulting in significant errors, making it difficult to meet user needs and causing inconvenience to users.

[0103] Based on this, this application proposes a grain processing device and control method for a grain storage assembly that automatically controls the rice output, saves time and labor, and has high accuracy in controlling the rice output.

[0104] See Figures 1-14 As shown, an embodiment of this application provides a silo assembly applied to a grain processing device. The silo assembly includes a silo body 1 and an opening / closing mechanism. The silo body 1 has a storage chamber 101 inside, and a first discharge port 102 at the bottom of the storage chamber 101. The inner wall of the storage chamber 101 includes a first-level inner wall surface 103, which is disposed near the first discharge port 102. The angle between the first-level inner wall surface 103 and a first direction is α, and the first direction is perpendicular to the discharge direction. The opening / closing mechanism is disposed on the silo body 1 and is used to open / close the first discharge port 102. The area of ​​the first discharge port 102 is S, which satisfies a preset area range, and the angle α satisfies a preset angle range. The opening / closing mechanism opens the first discharge port 102 according to the received user selection signal, so that the total discharge amount of the first discharge port 102 corresponds to the user selection signal.

[0105] In this type of storage container assembly, when the area S of the first discharge port 102 meets a preset area range and the angle α between the first-stage inner wall surface 103 and the first direction meets a preset angle range, the grain in the storage chamber 101 can fall and discharge quickly, accelerating the discharge speed and shortening the discharge time. Furthermore, the user selection signal corresponds to the user's desired discharge volume. Based on the received user selection signal, the opening and closing mechanism controls the first discharge port 102 to open, ensuring that the total discharge volume of the first discharge port 102 is essentially consistent with the user's desired discharge volume. This achieves automatic control of the rice discharge volume, saving time and effort, meeting user needs, and providing great convenience to users.

[0106] The hopper assembly of this application is used in a grain processing device for processing grains. For example, the grain processing device can be a rice milling machine, or optionally, a household rice milling machine. The rice milling machine has a rice milling hopper 18 and a grain processing mechanism. The rice milling hopper 18, in conjunction with the grain processing mechanism, can dehull paddy rice into fresh rice such as brown rice, germ-rich rice, and polished white rice. This rice milling machine has functions such as dehulling, grinding, and rice discharge, and features low noise, compatibility with multiple rice varieties, and fully automatic quantitative feeding.

[0107] The silo assembly includes silo body 1 (or rice silo), which has sufficient structural strength to support other internal structural components and hold the grain to be processed. See also... Figures 1-5 As shown, the overall structure of the container 1 in this application is a cuboid-like structure with a regular appearance, making it easy to install and set up.

[0108] The silo body 1 has a storage chamber 101 inside, which is used to store grains to be processed, such as rice. After the grains to be processed enter the storage chamber 101, they are temporarily stored in the storage chamber 101 for subsequent processing such as hulling. The bottom of the storage chamber 101 has a first discharge port 102, which is connected to the inside of the storage chamber 101. The grains to be processed stored in the storage chamber 101 can be discharged to the grain processing silo (such as the rice milling silo 18) through the first discharge port 102 for hulling and other processing. The specific capacity of the storage chamber 101 can be determined according to the size of the silo body 1 and other related structural layouts.

[0109] See Figure 4 As shown, the top of the storage chamber 101 has a feed inlet 108, through which the user can add grains to be processed into the storage chamber 101. The first discharge outlet 102 is located at the bottom of the storage chamber 101. When the first discharge outlet 102 is opened, the grains to be processed in the storage chamber 101 can fall from the first discharge outlet 102 into the grain processing bin (such as the rice milling bin 18) under the action of gravity, increasing the discharge rate and helping to reduce blockage of the first discharge outlet 102. The discharge direction of the first discharge outlet 102 is as follows: Figure 4The direction indicated by the middle arrow a. Moreover, the feed inlet 108 and the first discharge outlet 102 are arranged opposite each other in the vertical direction, making the structural layout of the silo 1 more reasonable and the utilization rate of the internal space of the silo 1 higher.

[0110] In one embodiment, with Figure 4 Taking the shown perspective as an example, the first discharge port 102 is positioned centered relative to the feed port 108 in the first direction, as shown in the first direction. Figure 4 In this embodiment, the first direction indicated by the middle arrow b is horizontal. This structural design allows the grains to be processed in the storage chamber 101 to move downwards more evenly and smoothly, further improving the discharge rate and reducing the occurrence of blockage at the first discharge port 102.

[0111] In one embodiment, the area of ​​the feed inlet 108 is larger than the area of ​​the first discharge outlet 102. The larger area of ​​the feed inlet 108 facilitates the user in adding the grain to be processed into the storage chamber 101, reducing grain spillage and improving operational convenience. The smaller area of ​​the first discharge outlet 102 allows for more accurate control of the discharge volume, ensuring that the discharge volume meets the user's needs.

[0112] In one embodiment, at least a portion of the cross-section of the storage cavity 101 gradually decreases from the inlet 108 to the first outlet 102. The cross-section refers to the section of the storage cavity 101 perpendicular to the discharge direction. That is, from the inlet 108 to the first outlet 102, the storage cavity 101 has at least a constricted structure, which facilitates a more even and smooth downward movement of the grains to be processed within the storage cavity 101. Specifically, the top of the inner wall of the storage cavity 101 is connected to the inlet 108, and the bottom is connected to the first outlet 102. Because the area of ​​the inlet 108 is larger than the area of ​​the first outlet 102, the inner wall of the storage cavity 101 has a funnel-shaped structure (i.e., a constricted structure) that is larger at the top and smaller at the bottom. This structure of the storage cavity 101 facilitates a faster and smoother downward movement of the grains along the inner wall of the storage cavity 101, further improving the discharge rate of the silo 1.

[0113] Specifically, the inner wall of the storage chamber 101 includes a first-stage inner wall surface 103, which is located near the first discharge port 102. The angle between the first-stage inner wall surface 103 and the first direction is α. During the falling of the grain, when the grain reaches the first-stage inner wall surface 103, the falling speed of the grain increases, making the falling of the grain smoother and reducing the blockage of the grain at the first discharge port 102. In one embodiment, the first direction is perpendicular to the discharge direction, the discharge direction is vertical, and the first direction is horizontal.

[0114] The silo assembly also includes an opening and closing mechanism for opening / closing the first discharge port 102. When the opening and closing mechanism controls the first discharge port 102 to open, the grain to be processed in the storage chamber 101 can be transported to the grain processing chamber of the grain processing device for further processing such as hulling. When the opening and closing mechanism controls the first discharge port 102 to close, the storage chamber 101 stops transporting the grain to be processed to the grain processing chamber.

[0115] The area S of the first discharge port 102 is the flow area of ​​the first discharge port 102, and the angle α between the first-stage inner wall surface 103 and the first direction is the slope of the first-stage inner wall surface 103 (or the material discharge slope of the inner wall of the storage chamber 101). When the first discharge port 102 is in the open state, the area S of the first discharge port 102 and the angle α between the first-stage inner wall surface 103 and the first direction will affect the speed at which the grain falls from the first discharge port 102.

[0116] The user selection signal corresponds to the user's required output amount (i.e., the amount of grain the user needs to use). Based on the received user selection signal, the opening and closing mechanism opens the first discharge port 102 so that the total output amount of the first discharge port 102 corresponds to the user selection signal. That is, the total output amount of the first discharge port 102 is consistent with or close to the user's required output amount, thereby meeting the user's usage needs.

[0117] Depending on the control method, the first discharge port 102 can have several discharge modes, including multiple discharge and one-time discharge. Under the control of the opening and closing mechanism, each opening and closing of the first discharge port 102 is counted as one discharge process. Therefore, multiple discharge means that the first discharge port 102 opens and closes multiple times, realizing multiple discharge processes. Multiple discharge is also a type of intermittent discharge. On the other hand, one-time discharge means that the first discharge port 102 opens and closes only once, realizing one discharge process. One-time discharge is also a type of continuous discharge.

[0118] Regardless of the discharge method adopted by the first discharge port 102, as long as the total discharge volume of the first discharge port 102 (which can be the cumulative discharge volume under multiple discharge methods or the one-time discharge volume under one-time discharge methods) corresponds to the user selection signal, it is acceptable.

[0119] In one embodiment of this application, the user selection signal includes a grain characteristic signal and a desired quantity signal. The opening and closing mechanism controls the single opening time of the first discharge port 102 to be T1 according to the grain characteristic signal, and controls the opening and closing mechanism to open the first discharge port 102 a number of times according to the desired quantity signal.

[0120] In one embodiment, the first discharge port 102 is controlled by a multiple discharge method. The basic control logic of the multiple discharge method is: to make the discharge amount (single discharge amount) of the first discharge port 102 each time it opens a constant value (or basically a constant value), and then to obtain the required total discharge amount by adjusting the number of times the first discharge port 102 opens N (N is a positive integer). This total discharge amount matches the user's required discharge amount. Since different grains have different characteristics, including the weight, shape, volume, and moisture content of a single grain, the discharge speed per unit time will be different due to the different discharge resistance of different grains. Therefore, for grains with different characteristics, it is necessary to adjust the single opening time T1 (T1 is a positive number) of the first discharge port 102 so that the discharge amount (single discharge amount) of the first discharge port 102 each time it opens is a constant value (or basically a constant value).

[0121] In one embodiment, the user selection signal includes a grain characteristic signal and a desired quantity signal. The grain characteristic signal characterizes the characteristics of the grain, and grains with different characteristics have different discharge rates (discharge resistance). The single opening time T1 of the first discharge port is determined based on the grain characteristic signal to precisely control the discharge amount per single opening of the first discharge port, thereby improving discharge accuracy and reducing errors.

[0122] The amount of material discharged each time the first discharge port 102 is opened, that is, the amount of material discharged in a single opening of the first discharge port 102, or the single discharge amount, is also called a portion of the discharge amount. For different models, a portion of the discharge amount can be a cup of material, a bowl of material, etc.

[0123] The number of times N of opening the first discharge port 102 is determined based on the required number of portions signal. For example, if the required number of portions signal is one, the corresponding number of times N of opening the first discharge port 102 is 1; if the required number of portions signal is two, the corresponding number of times N of opening the first discharge port 102 is 2; if the required number of portions signal is three, the corresponding number of times N of opening the first discharge port 102 is 3, and so on.

[0124] After determining the single opening time T1 and the number of openings N of the first discharge port 102, the opening and closing mechanism controls the first discharge port 102 to open and discharge material according to the single opening time T1 and the number of openings N. After the material is discharged, the total discharge amount of the first discharge port 102 is the cumulative value of N discharges. This total discharge amount corresponds to the user selection signal, meets the user's needs, and has high discharge amount control accuracy.

[0125] In one embodiment, when the first discharge port 102 is controlled in a multiple discharge mode, grain discharge and grain processing are performed alternately. Taking an opening frequency N of 2 times as an example, after the first discharge port 102 opens for the first time, the grain discharge amount is 180g. Then, the grain processing mechanism grinds this portion of grain, and after processing, the processed grain (such as rice) is discharged. Then, the first discharge port 102 opens for the second time, and the grain discharge amount is 180g. Then, the grain processing mechanism grinds this portion of grain again, and after processing, the processed grain is discharged.

[0126] In one embodiment of this application, the grain feature signal includes a grain type signal or a grain shape signal.

[0127] In one embodiment, the grain characteristic signal includes a grain type signal or a grain shape signal, wherein the grain type signal includes indica rice, japonica rice, glutinous rice, etc. Different types of grains have different weights, volumes, shapes, moisture contents, etc. When the first discharge port 102 is in the open state, the discharge speed (discharge resistance) of different types of grains is different. The single opening time T1 of the first discharge port 102 can be determined according to the grain type to adjust the discharge amount (i.e., single discharge amount) of the first discharge port 102 within the single opening time T1, so that the discharge amount (i.e., single discharge amount) of the first discharge port 102 each time it opens is a constant value (or basically a constant value), which facilitates discharge control and helps to improve the discharge control accuracy.

[0128] Similarly, the grain shape signal includes round-grain rice and long-grain rice. Generally, the movement resistance (i.e. discharge resistance) of round-grain rice is smaller, while the movement resistance (i.e. discharge resistance) of long-grain rice is larger. The single opening time T1 of the first discharge port 102 can be determined solely based on the shape of the grain to adjust the discharge amount of the first discharge port 102 within the single opening time T1, thereby simplifying the control logic while ensuring the accuracy of discharge amount control.

[0129] For example, when the grain shape signal is round-grained rice, the single opening time T1 can be set to be smaller, and when the grain shape signal is long-grained rice, the single opening time T1 can be set to be larger.

[0130] In one embodiment of this application, the discharge amount of the first discharge port 102 within a single opening time T1 is 180g-200g.

[0131] Because the grain processing equipment operates by processing the grain after each discharge from the first outlet 102, the amount of grain discharged from the first outlet 102 within a single opening time T1 (referred to as the single discharge volume) is directly related to the processing effect of the grain processing mechanism. If the single discharge volume is too high, the single grain processing time will be long, which may cause some grain to be crushed and the grinding effect to be poor. If the single discharge volume is too low, the number of grain processing times will increase, thus prolonging the user's waiting time.

[0132] In one embodiment, the discharge volume of the first discharge port 102 within a single opening time T1 ranges from 180g to 200g. Within this parameter range, the single grain processing time can be shortened, ensuring the grain processing effect (i.e., grinding effect) without excessively increasing the user's waiting time, thus achieving a balance between grain processing time and processing effect, while meeting the user's daily needs.

[0133] For example, the discharge amount of the first discharge port 102 within a single opening time T1 can be 180g, 185g, 192g, 196g, 200g, etc.

[0134] In one embodiment of this application, the user selection signal includes a desired grain volume signal, and the opening and closing mechanism opens the first discharge port 102 according to the desired grain volume signal and continues for a corresponding preset time T2.

[0135] In one embodiment, the first discharge port 102 is controlled as a one-time discharge method. The basic logic of the one-time discharge method is that the first discharge port 102 is opened only once, and different total discharge volumes are achieved by adjusting the duration of the opening of the first discharge port 102 (i.e., a preset time T2, where T2 is a positive number). This total discharge volume matches the user's required discharge volume.

[0136] In one embodiment, the user selection signal includes a required grain quantity signal, which represents the user's desired output amount, i.e., the amount of grain the user currently needs. Based on the user's desired output amount, the first discharge port 102 is controlled to remain open for a preset time T2, achieving continuous grain output, simplifying the control logic, improving output accuracy, reducing output errors, meeting user needs, and bringing great convenience to the user.

[0137] In one embodiment of this application, the preset time T2 is in the range of 3s-15s.

[0138] In one embodiment, the preset time T2 ranges from 3s to 15s. Within this range, the user's daily grain consumption needs can be met without causing the user to wait for an extended period. Understandably, the user's required output is proportional to the preset time T2. For example, if the user requires a smaller output, the preset time T2 can be set shorter; if the user requires a larger output, the preset time T2 can be set longer.

[0139] For example, the preset time T2 can be 3s, 5s, 7.5s, 8s, 10s, 12.5s, 15s, etc.

[0140] In one embodiment of this application, the inner wall of the storage cavity 101 further includes a second-level inner wall surface 104, which is connected to the end of the first-level inner wall surface 103 away from the first discharge port 102, and the first-level inner wall surface 103 and the second-level inner wall surface 104 are set at an angle.

[0141] See Figure 4 As shown, the inner wall of the storage cavity 101 has a funnel-shaped structure that is larger at the top and smaller at the bottom. The inner wall of the storage cavity 101 also includes a second-level inner wall surface 104. The lower edge of the second-level inner wall surface 104 is connected to the upper edge of the first-level inner wall surface 103. The first-level inner wall surface 103 and the second-level inner wall surface 104 together form the inner wall of the storage cavity 101.

[0142] In one embodiment, the first-level inner wall surface 103 and the second-level inner wall surface 104 are set at an angle, that is, the first-level inner wall surface 103 and the second-level inner wall surface 104 on the same side are not on the same plane, so that the inner wall of the storage cavity 101 presents a multi-level structure.

[0143] Furthermore, the angle between the first-level inner wall surface 103 and the second-level inner wall surface 104 can be adjusted as needed. For example, when the second-level inner wall surface 104 is inclined outward relative to the first-level inner wall surface 103, the second-level inner wall surface 104 is more gentle than the first-level inner wall surface 103, making the cross-sectional dimension of the upper part of the storage cavity 101 larger and increasing the internal capacity of the storage cavity 101. Or, when the second-level inner wall surface 104 is inclined inward relative to the first-level inner wall surface 103, the second-level inner wall surface 104 is steeper than the first-level inner wall surface 103, so that the material discharge speed of the first discharge port 102 is faster, thereby meeting the setting requirements of different products and making the product structure design flexible and diverse.

[0144] In one embodiment of this application, the angle between the second-level inner wall surface 104 and the first direction is β, and the value of the angle β is in the range of 0° < β < α.

[0145] See Figure 4 As shown, the angle between the second-stage inner wall surface 104 and the first direction is β, and the first direction is perpendicular to the discharge direction. Figure 4The direction indicated by the middle arrow b. In one embodiment, the included angle β ranges from 0° to β to α, that is, the slope of the second-level inner wall surface 104 is less than the slope of the first-level inner wall surface 103. The second-level inner wall surface 104 is gentler than the first-level inner wall surface 103, making the upper part of the storage cavity 101 have an outward expansion structure, thereby increasing the internal volume of the storage cavity 101. Moreover, since the second-level inner wall surface 104 is set far away from the first discharge port 102, the above setting will not affect the discharge speed of the first discharge port 102.

[0146] For example, the included angle β can be 10°, 15°, 20°, 22°, 28°, etc.

[0147] In one embodiment of this application, the preset area range is S≥30mm. 2 And / or the preset angle range is α≥30°.

[0148] In one embodiment, the preset area range is S≥30mm. 2 That is, the area S of the first discharge port 102 is in the range of S≥30mm. 2 The area S of the first discharge port 102 is within the above-mentioned range, ensuring that the grains falling from the first discharge port 102 will not clog it, thus ensuring smooth falling of the grains (such as rice). For example, the area S of the first discharge port 102 can be 700 mm². 2 500mm 2 200mm 2 50mm 2 45mm 2 42mm 2 30mm 2 wait.

[0149] In one embodiment, the preset angle range is α ≥ 30°, meaning the angle α between the first-stage inner wall surface 103 and the first direction is α ≥ 30°. When the angle α between the first-stage inner wall surface 103 and the first direction is within this range, it ensures that the grain can smoothly slide into the first discharge port 102, increasing the grain's falling speed. For example, the angle α can be 60°, 45°, 32°, 30°, etc.

[0150] In one embodiment, the preset area range S≥30mm is simultaneously satisfied. 2 The preset angle range is α≥30°. By coordinating the material discharge slope of the inner wall of the storage chamber 101 and the area of ​​the first discharge port 102, the working efficiency requirements of the fully automatic rice milling machine in the rice feeding stage (discharging stage) in the home setting can be met. Compared with the existing technology that requires manual rice addition, it can ensure that the first discharge port 102 does not become blocked, with shorter processing time and more efficient and intelligent operation.

[0151] In one embodiment, see [reference] Figure 5 As shown, the first discharge port 102 is a rectangular discharge port. This shape facilitates cooperation with the opening and closing mechanism and improves structural reliability. The length of the first discharge port 102 is X, and the width is Y, where X ≥ 6mm and Y ≥ 5mm, to satisfy the requirement that the area S of the first discharge port 102 ≥ 30mm². 2 .

[0152] In other embodiments, the first discharge port 102 may also be a square, circular, or other discharge port.

[0153] In one embodiment of this application, the interior of the hopper 1 also has an installation cavity 105, which is separated from the storage cavity 101, and the opening and closing mechanism is detachably installed in the installation cavity 105.

[0154] See Figure 14 As shown, the interior of the silo body 1 also has an installation cavity 105, and the storage cavity 101 and the installation cavity 105 are separated from each other, and are not connected to or affect each other. The installation cavity 105 is used to install other structures of the silo body assembly, and the specific capacity of the installation cavity 105 can be determined according to the size of the silo body 1 and other related structural layouts.

[0155] The opening and closing mechanism is detachably installed within the mounting cavity 105. This mechanism does not occupy external space of the silo body 1; by integrating it into the interior of the silo body 1, the silo assembly forms a single, integrated structure. This results in a compact structure, high space utilization, and a neat appearance, facilitating the miniaturization of the entire machine. The external structure of the silo assembly is free of redundancy, simplifying installation. Furthermore, since the opening and closing mechanism is located inside the silo body 1, and the connection point between them is also inside the silo body 1, external forces will not affect the connection strength between the opening and closing mechanism and the silo body 1, preventing loosening and significantly improving structural reliability and stability, ensuring the normal operation of the grain processing device. The connection between the opening and closing mechanism and the silo body 1 is less prone to loosening, resulting in good sealing and preventing leakage of grain particles or flour. This improves the overall cleanliness of the machine and enhances the user experience.

[0156] In one embodiment, the opening and closing mechanism is located near the bottom of the mounting cavity 105, which facilitates installation, maintenance, and replacement of the mechanism. Furthermore, the opening and closing mechanism is closer to the first discharge port 102, making it easier to control the opening and closing of the first discharge port 102.

[0157] In one embodiment of this application, the opening and closing mechanism includes a baffle 2, which has a first position for opening the first discharge port 102 and a second position for closing the first discharge port 102. The baffle 2 can be controllably moved back and forth between the first position and the second position.

[0158] The opening and closing mechanism includes a baffle 2, which has a first position with the first discharge port 102 open and a second position with the first discharge port 102 closed. The baffle 2 can be controllably moved back and forth between the first and second positions. By moving the baffle 2 back and forth between the first and second positions, the opening or closing of the first discharge port 102 can be easily achieved. Furthermore, the baffle 2 has a plate-like structure with a small overall thickness, which does not occupy too much installation space and allows for a more compact structure of the hopper assembly.

[0159] In one embodiment, the reciprocating movement direction of the baffle 2 is a first direction.

[0160] In one embodiment of this application, the hopper body 1 further includes a bottom cover 106, which is detachably connected to the bottom of the storage chamber 101. The bottom cover 106 has a second discharge port 107 corresponding to the first discharge port 102. The baffle 2 is movably disposed between the storage chamber 101 and the bottom cover 106.

[0161] The compartment 1 also includes a bottom cover 106, which is disposed at the bottom of the compartment 1 so that the opening and closing mechanism and the like are disposed inside the compartment 1. In one embodiment, the bottom cover 106 is detachably connected to the bottom of the compartment 1 so as to allow for the installation and maintenance of the opening and closing mechanism and the like inside the compartment 1.

[0162] In one embodiment, the bottom cover 106 can be detachably connected to the bottom of the storage cavity 101 via a snap-fit ​​structure. See also... Figure 2 As shown, the snap-fit ​​structure includes a fixing buckle 1201 and a fixing buckle position 1202. One of the fixing buckles 1201 and the fixing buckle position 1202 is located on the side of the bottom cover 106 facing the storage cavity 101, and the other is located on the side of the storage cavity 101 facing the bottom cover 106. Specifically, the fixing buckle 1201 is located on the side of the storage cavity 101 facing the bottom cover 106, i.e., the bottom of the storage cavity 101, and the fixing buckle position 1202 is located on the side of the bottom cover 106 facing the storage cavity 101, i.e., the upper surface of the bottom cover 106. There are two fixing buckles 1201, which are spaced apart, and there are also two fixing buckle positions 1202, whose positions correspond to the positions of the fixing buckles 1201. The fixing buckles 1201 and the fixing buckle positions 1202 can be fastened together to achieve the installation of the bottom cover 106 and the storage cavity 101.

[0163] In one embodiment, the bottom cover 106 is also fastened to the bottom of the compartment 1 to enhance the connection strength between the bottom cover 106 and the compartment 1 and improve structural reliability.

[0164] See Figures 2-3As shown, the bottom cover 106 has a second discharge port 107, and the second discharge port 107 corresponds to the position of the first discharge port 102. In the discharge direction, the second discharge port 107 is located below the first discharge port 102, and the grain to be processed in the storage chamber 101 can fall into the rice milling hopper 18 and the grain processing mechanism under the action of gravity through the first discharge port 102 and the second discharge port 107. In one embodiment, the second discharge port 107 is the same size and shape as the first discharge port 102 to facilitate the falling of grain and to help reduce grain blockage problems.

[0165] The opening and closing mechanism is located inside the silo body 1, between the storage chamber 101 and the bottom cover 106, allowing the baffle 2 to be movably positioned between the storage chamber 101 and the bottom cover 106 for convenient opening and closing of the first discharge port 102. Specifically, when the baffle 2 opens the first discharge port 102, the first discharge port 102 is connected to the second discharge port 107, allowing the grain in the storage chamber 101 to fall. When the baffle 2 closes the first discharge port 102, the first discharge port 102 is not connected to the second discharge port 107, preventing the grain in the storage chamber 101 from falling.

[0166] In one embodiment of this application, the opening and closing mechanism further includes a mounting plate 3, which is disposed between the storage cavity 101 and the bottom cover 106. A baffle 2 is movably disposed on the mounting plate 3, and the mounting plate 3 has a third discharge port 301 corresponding to the first discharge port 102.

[0167] See Figures 2-3 , Figures 6-7 As shown, the opening and closing mechanism includes a mounting plate 3, which is installed inside the hopper 1. Specifically, at least two connecting posts 13 are provided on the side of the bottom cover 106 facing the storage cavity 101 (i.e., the upper surface of the bottom cover 106), and corresponding connecting holes are provided on the mounting plate 3. The mounting plate 3 can be fixed to the bottom cover 106 by bolts or other fasteners. The mounting plate 3 has a plate-like structure, and its extension direction is parallel to the bottom cover 106. Specifically, the mounting plate 3 is disposed between the storage cavity 101 and the bottom cover 106, and the baffle 2 is movably disposed on the mounting plate 3, so that the baffle 2 is placed between the storage cavity 101 and the bottom cover 106, thereby realizing the opening and closing of the first discharge port 102.

[0168] In one embodiment, the mounting plate 3 has a third discharge port 301, which is correspondingly disposed to the first discharge port 102 and also correspondingly disposed to the second discharge port 107. In the discharge direction, the third discharge port 301 is located above the second discharge port 107.

[0169] In one embodiment of this application, the size of the third discharge port 301 is larger than the size of the first discharge port 102, and the first discharge port 102 is adapted to be inserted into the third discharge port 301.

[0170] The shape of the third discharge port 301 is the same as that of the first discharge port 102 and the second discharge port 107, but the size of the third discharge port 301 is larger than that of the first discharge port 102, so that the first discharge port 102 can be inserted into the third discharge port 301. The inner wall of the third discharge port 301 wraps around the edge of the first discharge port 102, thereby positioning the first discharge port 102 and ensuring that the grain falling from the first discharge port 102 can be input into the rice milling bin 18 and the grain processing mechanism through the opening and closing mechanism, thereby improving the reliability of the structure.

[0171] In one embodiment, the opening and closing mechanism further includes a drive member 10, a gear 11, and a push rod 5. The drive member 10 is disposed on the mounting plate 3 and is used to drive the baffle 2 to move, providing power for the opening / closing process of the first discharge port 102. Specifically, a mounting hole 14 is provided on the side of the mounting plate 3 facing the storage cavity 101 (i.e., the upper surface of the mounting plate 3). The drive member 10 can be installed and fixed to the mounting plate 3 by the cooperation of fasteners such as bolts with the mounting hole 14.

[0172] The mounting plate 3 has a groove on the side facing away from the drive member 10. The extension direction of the groove is consistent with the reciprocating movement direction of the baffle 2. The push rod 5 is slidably disposed in the groove. The end of the push rod 5 near the first discharge port 102 is fixed to the baffle 2 so that the push rod 5 and the baffle 2 move synchronously.

[0173] The driving end of the driving member 10 is connected to the rotating shaft of the gear 11, and the gear 11 can rotate around its own axis under the drive of the driving member 10. The length direction of the push rod 5 is consistent with the moving direction of the baffle 2, and a rack portion 501 is provided on the side of the push rod 5 facing the gear 11, and the gear 11 meshes with the rack portion 501. Under the drive of the driving member 10, the gear 11 rotates around its own axis (forward or reverse), and the gear 11 drives the push rod 5 to move back and forth along its length direction. At the same time, the baffle 2 can move back and forth between the first position and the second position, thereby realizing the opening / closing control of the first discharge port 102. In one embodiment, the driving member 10 is a motor, specifically a stepper motor.

[0174] In one embodiment of this application, the opening and closing mechanism further includes a reinforcing plate 4, which is disposed in a portion of the area between the baffle 2 and the mounting plate 3, and the reinforcing plate 4 is used to support the mounting plate 3.

[0175] See Figure 3 and Figure 8As shown, the opening and closing mechanism also includes a reinforcing plate 4, which is disposed in a portion of the area between the baffle 2 and the mounting plate 3. Specifically, the size of the reinforcing plate 4 is smaller than the size of the mounting plate 3 and the baffle 2. The reinforcing plate 4 is disposed in a portion of the area between the baffle 2 and the mounting plate 3 to support the mounting plate 3 and prevent the mounting plate 3 from shaking during the reciprocating movement of the baffle 2, thus affecting the structural stability.

[0176] In one embodiment, the mounting plate 3 is made of plastic, and the reinforcing plate 4 is made of metal. The reinforcing plate 4 is fixed to the mounting plate 3, and the baffle 2 can reciprocate relative to the mounting plate 3 and the reinforcing plate 4. The structural strength of the reinforcing plate 4 is higher than that of the mounting plate 3, so as to achieve the support of the mounting plate 3 by the reinforcing plate 4. At the same time, since the reinforcing plate 4 is made of metal, its surface is relatively smooth, which can reduce the resistance when the baffle 2 reciprocates, making the movement of the baffle 2 smoother.

[0177] See Figure 3 As shown, the reinforcing plate 4 has a fourth discharge port 401, which corresponds to the third discharge port 301 in position and has the same size and shape, so that the fourth discharge port 401 corresponds to the first discharge port 102 in position and has the same size and shape, so as to realize the falling of grain.

[0178] In one embodiment of this application, the baffle 2 has a communication port 201. When the baffle 2 is in the first position, the communication port 201 is connected to the first discharge port 102. When the baffle 2 is in the second position, the communication port 201 is misaligned with the first discharge port 102, and the first discharge port 102 is blocked by the baffle 2.

[0179] See Figure 3 As shown, the baffle 2 has a connecting opening 201, the shape and size of which are the same as the first discharge port 102. When the baffle 2 is in the first position, the connecting opening 201 is connected to the first discharge port 102, and the grain in the storage chamber 101 can fall through the first discharge port 102. When the baffle 2 is in the second position, the connecting opening 201 is misaligned with the first discharge port 102, the first discharge port 102 is blocked by the baffle 2, and the grain in the storage chamber 101 cannot fall through the discharge port.

[0180] The baffle 2 of this structure has a short travel distance between the first and second positions and high reliability, which is conducive to quickly opening or closing the first discharge port 102 and meeting the user's needs for rapid response to material discharge from the silo assembly.

[0181] In one embodiment of this application, the opening and closing mechanism further includes a positioning detection component, which is used to detect whether the baffle 2 has moved to a first position and whether it has moved to a second position.

[0182] To improve the reliability of the opening and closing mechanism, a positioning detection component is also included. During the opening of the first discharge port 102, the positioning detection component detects whether the baffle 2 has moved to a first position, aligning the connecting port 201 with the first discharge port 102. In other words, the positioning detection component detects whether the first discharge port 102 is fully open. If the first discharge port 102 is fully open, the drive component 10 is deactivated, stopping the baffle 2 from moving, ensuring smooth material discharge from the first discharge port 102 and preventing overload of the drive component 10, thus improving structural reliability. During the closing of the first discharge port 102, the positioning detection component detects whether the baffle 2 has moved to a second position, offsetting the connecting port 201 from the first discharge port 102. In other words, the positioning detection component detects whether the first discharge port 102 is fully closed. If the first discharge port 102 is fully closed, the drive component 10 is deactivated, stopping the baffle 2 from moving, preventing overload of the drive component 10, and improving structural reliability.

[0183] In one embodiment of this application, the opening and closing mechanism further includes a push rod 5, one end of which near the first discharge port 102 is connected to a baffle 2; the positioning detection component includes a detection component 6, a first trigger 7, and a second trigger 8. The detection component 6 is disposed on the mounting plate 3, and the first trigger 7 and the second trigger 8 are disposed at intervals on the push rod 5. When the first trigger 7 is configured to contact the detection component 6, the baffle 2 moves to a first position, and when the second trigger 8 is configured to contact the detection component 6, the baffle 2 moves to a second position.

[0184] See Figure 9 and Figure 10 As shown, the positioning detection component includes a detection element 6, a first trigger element 7, and a second trigger element 8. The detection element 6 is disposed on the mounting plate 3. In one embodiment, the detection element 6 is a micro switch. The first trigger element 7 and the second trigger element 8 are spaced apart from each other on the push rod 5. The first trigger element 7 and the second trigger element 8 reciprocate together with the push rod 5 in a first direction. The detection element 6 can cooperate with the first trigger element 7 and the second trigger element 8 to respectively determine whether the baffle 2 has reached the first position and whether it has reached the second position.

[0185] In one embodiment, the mounting plate 3 is provided with a mounting position 15, and the detection component 6 is mounted in the mounting position 15 via a mounting mechanism. Specifically, see [reference needed]. Figures 7-11 As shown, the detection component 6 has a cuboid-like structure. The mounting mechanism includes two limiting posts 16 and two limiting buckles 17. Two limiting posts 16 are provided, arranged diagonally opposite each other. Two limiting buckles 17 are provided, arranged opposite each other. The detection component 6 has a limiting hole 601, which is suitable for inserting the limiting post 16 to position the detection component 6. The limiting buckles 17 are suitable for engaging the upper surface of the detection component 6 to prevent it from dislodging from the mounting position 15, thereby completing the installation of the detection component 6.

[0186] In one embodiment, see [reference] Figure 10 As shown, the detection component 6 includes a housing, a detection rod 602, and a detection part 603. The detection rod 602 is elastic, and one end of the detection rod 602 extends from the housing and connects to the detection part 603. The outer wall of the housing is also provided with a trigger part 604. Specifically, the detection part 603 is a roller structure, and the first trigger 7 and the second trigger 8 are both partial sidewalls of the push rod 5. When the detection part 603 contacts the first trigger 7 or the second trigger 8, the detection part 603 can roll relative to the first trigger 7 or the second trigger 8 so as not to affect the movement of the push rod 5 and the baffle 2, thus avoiding structural interference. When the detection part 603 contacts the first trigger 7 or the second trigger 8, the detection rod 602 is forced to swing inward until the inner side of the detection part 603 contacts the trigger part 604, triggering a detection signal.

[0187] During the opening of the first discharge port 102, the baffle 2 and push rod 5 move under the drive of the drive unit 10. When the first trigger 7 contacts the detection unit 603, a detection signal is triggered. At this time, the baffle 2 reaches the first position, the connecting port 201 is aligned with the first discharge port 102, the first discharge port 102 is fully open, the drive unit 10 is closed, and the baffle 2 and push rod 5 stop moving. During the closing of the first discharge port 102, the baffle 2 and push rod 5 move under the drive of the drive unit 10. When the second trigger 8 contacts the detection unit 603, a detection signal is triggered. At this time, the baffle 2 reaches the second position, the connecting port 201 is misaligned with the first discharge port 102, the first discharge port 102 is fully closed by the baffle 2, the drive unit 10 is closed, and the baffle 2 and push rod 5 stop moving.

[0188] See Figure 14 As shown, one embodiment of this application also provides a grain processing device, including: a housing 9, the aforementioned hopper assembly, and a control module. The hopper assembly is detachably or fixedly connected to the top of the housing 9. The control module is electrically connected to the opening and closing mechanism. The control module controls the opening and closing mechanism to open the first discharge port 102 according to the received user selection signal, so that the total discharge amount of the first discharge port 102 corresponds to the user selection signal.

[0189] The grain processing device includes a shell 9, which is the main structure of the grain processing device and has a certain structural strength to support and house other structural components of the grain processing device. The shell 9 has a shell receiving cavity inside, and a grain processing mechanism, such as a rice milling mechanism, is installed in the shell receiving cavity to perform dehulling, grinding and other processing on the grain.

[0190] In one embodiment, the housing 9 and the hopper assembly are separate units, detachably connected to the housing 9. They can be assembled to form the complete machine structure for ease of use. For example, when the grain to be processed in the storage chamber 101 of the hopper 1 is insufficient, the hopper assembly can be removed from the housing 9, grain to be processed can be added to the storage chamber 101, and then the hopper assembly can be reinstalled onto the housing 9. This structural design facilitates the addition of grain, improves the flexibility of the machine's use, and the separate hopper assembly from the housing 9 allows for easier cleaning of the internal and external structures, enhancing user convenience.

[0191] Furthermore, the silo assembly is detachably connected to the top of the housing 9. Specifically, the bottom of the silo assembly can be installed on the top of the housing 9. This grain processing device makes full use of the vertical installation space, making its horizontal dimensions smaller and its structure more compact. It reduces the horizontal space occupation, improves the utilization rate of the installation space, and thus facilitates the installation and setup of the grain processing device, improving the flexibility of the grain processing device setup.

[0192] In one embodiment, the silo assembly is fixedly connected to the top of the housing 9, that is, the silo assembly is fixed to the top of the housing 9. At this time, the grain processing device forms an integrated structure, which is convenient for movement and use and has good structural reliability.

[0193] The control module is used to control the overall operation of the grain processing device. The control module is electrically connected to the opening and closing mechanism. Based on the received user selection signal, the control module controls the opening and closing mechanism to open the first discharge port 102, so that the total discharge volume of the first discharge port 102 corresponds to the user selection signal. Of course, the control module is also electrically connected to the grain processing mechanism, etc., which will not be elaborated here.

[0194] In one embodiment of this application, the grain processing device is a rice milling machine.

[0195] This grain processing device is used to process grains. For example, the grain processing device can be a rice milling machine. Optionally, the grain processing device is a household rice milling machine. The rice milling machine has a rice milling chamber 18 and a grain processing mechanism. The rice milling chamber 18 works in conjunction with the grain processing mechanism to dehull paddy rice and turn it into fresh rice such as brown rice, germ rice, and polished white rice. This rice milling machine has functions such as dehulling, grinding, and rice discharge, and features low noise, compatibility with multiple rice varieties, and fully automatic quantitative feeding.

[0196] In one embodiment, the grain processing apparatus also includes a control panel disposed on the outer wall of the housing 9, and a control module electrically connected to the control panel. The user can input a user selection signal into the grain processing apparatus by operating the control panel. The control panel sends the user selection signal to the control module, which then controls the opening and closing mechanism to open the first discharge port 102 according to the user selection signal, so that the total discharge volume of the first discharge port 102 corresponds to the user selection signal.

[0197] This application also provides a control method executed by the above-mentioned grain processing device. The control method includes: controlling the opening of the first discharge port 102 according to the user selection signal, so that the total discharge amount of the first discharge port 102 corresponds to the user selection signal.

[0198] The user selection signal corresponds to the user's required output amount. Based on the received user selection signal, the opening and closing mechanism is controlled to open the first discharge port 102 so that the total output amount of the first discharge port 102 corresponds to the user selection signal. This means that the total output amount of the first discharge port 102 is consistent with or close to the user's required output amount, thereby meeting the user's needs.

[0199] In one embodiment of this application, the user selection signal includes a grain characteristic signal and a desired quantity signal; the control method includes: determining a single opening time T1 of the first discharge port 102 based on the grain characteristic signal; determining the number of times N the first discharge port 102 is opened based on the desired quantity signal; controlling the first discharge port 102 to open according to the single opening time T1 and the number of openings N, and discharging grain; after the first discharge port 102 has been opened N times, controlling the first discharge port 102 to close.

[0200] In one embodiment, the first discharge port 102 is controlled in a multiple discharge mode. The user selection signal includes a grain characteristic signal and a desired quantity signal. In this case, the control method includes:

[0201] Step S101: Determine the single opening time T1 of the first discharge port 102 based on the grain characteristic signal.

[0202] The control module receives the grain characteristic signal sent by the control panel and determines the single opening time T1 of the first discharge port based on the grain characteristic signal, so as to accurately control the discharge amount of the first discharge port in a single opening.

[0203] Taking the grain shape signal as an example, see the table below:

[0204]

[0205] As shown in the table above, when the grain shape signal is round-grain rice, the grain to be processed is round-grain rice. When the single opening time T1 is 4s, the single output is within the range of 180g-200g, which meets the design requirements. However, when the single opening time T1 is 4s±0.2s, the single output exceeds the range of 180g-200g, which does not meet the design requirements.

[0206] Similarly, when the grain shape signal is long-grain rice, it means that the grain to be processed is long-grain rice. When the single opening time T1 is 4.5s, the single output is within the range of 180g-200g, which meets the design requirements. However, when the single opening time T1 is 4s±0.3s, the single output will exceed the range of 180g-200g, which does not meet the design requirements.

[0207] Step S102: Determine the number of times N the first discharge port 102 is opened based on the required number of portions signal.

[0208] The single dispensing quantity refers to one serving. Taking one serving as an example (one cup), the required serving quantity signal can be one cup, two cups, three cups, four cups, etc. This required serving quantity signal can be input via the control panel. The number of times the first dispensing port 102 opens, N, corresponds to the required serving quantity signal. For example, if the required serving quantity signal is one cup, the corresponding number of times the first dispensing port 102 opens, N, is 1; if the required serving quantity signal is two cups, the corresponding number of times the first dispensing port 102 opens, N, is 2; and if the required serving quantity signal is three cups, the corresponding number of times the first dispensing port 102 opens, N, is 3.

[0209] In step S103, the first discharge port 102 is opened according to the single opening time T1 and the number of openings N, and the grain is discharged.

[0210] After determining the single opening time T1 and the number of openings N of the first discharge port 102, the opening and closing mechanism controls the discharge of material from the first discharge port 102 according to the single opening time T1 and the number of openings N. After the discharge is completed, the total discharge amount of the first discharge port 102 is the cumulative value of N discharges. This total discharge amount corresponds to the user selection signal, meets the user's needs, and has high discharge amount control accuracy.

[0211] The opening process of the first discharge port 102 is as follows: the control module issues a control command to the opening and closing mechanism, the drive component 10 moves the baffle 2 from the second position to the first position, and the first discharge port 102 gradually opens, allowing the grain in the storage chamber 101 to fall from the first discharge port 102 into the rice milling hopper 18. When the single opening time reaches T1, the drive baffle 2 moves from the first position to the second position, and the first discharge port 102 gradually closes, thus completing one opening process of the first discharge port 102. The above process is repeated until the number of times the first discharge port 102 has been opened is N.

[0212] Step S104: After the first discharge port 102 has been opened N times, the first discharge port 102 is controlled to close.

[0213] After the opening and closing mechanism controls the first discharge port 102 to open N times, the discharge is completed, and the first discharge port 102 is closed. At this time, the total discharge amount of the first discharge port 102 is the cumulative value of the discharge amount of N times.

[0214] In one embodiment of this application, the step of controlling the opening of the first discharge port 102 to discharge grain, with a single opening time of T1 and an opening count of N, includes:

[0215] Each time the first discharge port 102 is opened, the discharged grain is processed. After processing is completed, the first discharge port 102 is opened again, until the number of times the first discharge port 102 is opened is N.

[0216] The above control method processes the grain after each discharge, and then discharges again after processing is completed. This ensures that the amount of grain processed each time is neither too much nor too little, achieving a balance between processing time and processing effect, simplifying control logic, and improving user experience.

[0217] In one embodiment of this application, the user selection signal includes a desired grain quantity signal; the control method includes: determining a preset time T2 for opening the first discharge port 102 and continuing it based on the desired output quantity corresponding to the desired grain quantity signal; controlling the first discharge port 102 to open and discharge grain; and controlling the first discharge port 102 to close after it has been open for the preset time T2.

[0218] In one embodiment, the first discharge port 102 is controlled in a one-time discharge mode. The user selection signal includes the desired valley quantity signal; in this case, the control method includes:

[0219] Step S201: Based on the required output amount corresponding to the required valley volume signal, determine the preset time T2 for opening the first discharge port 102 and continuing it.

[0220] The control module receives the required grain volume signal sent by the control panel and obtains the grain volume required by the user corresponding to the required grain volume signal. Then, the control module determines the opening and closing mechanism to open the first discharge port 102 and continue for a preset time T2 based on the required grain volume signal.

[0221] Step S202: Control the first discharge port 102 to open, and the grain is discharged.

[0222] The control module sends a control command to the opening and closing mechanism. The drive component 10 drives the baffle 2 to move from the second position to the first position. The first discharge port 102 gradually opens, and the grain in the storage chamber 101 falls from the first discharge port 102 to the rice milling bin 18.

[0223] It should be noted that the preset time T2 is the duration for the opening and closing mechanism to continuously open the first discharge port 102 once, referring to the total time from the initial opening to full opening, and then from the initial closing to full closing. When the baffle 2 reaches the first position, the control module issues a control command to the opening and closing mechanism, and the drive component 10 drives the baffle 2 to move from the first position to the second position. During this process, the grain in the storage chamber 101 continues to fall from the first discharge port 102 into the rice milling hopper 18. In other words, the first discharge port 102 will discharge material during both the opening and closing processes.

[0224] Step S203: After the first discharge port 102 is opened and maintained for a preset time T2, the first discharge port 102 is controlled to close.

[0225] When the first discharge port 102 is opened and remains open for a preset time T2, the drive component 10 drives the baffle 2 to the second position, at which point the first discharge port 102 is completely closed, completing the grain feeding process. At this time, the single discharge volume of the first discharge port 102 is the total discharge volume.

[0226] In one embodiment, the first discharge port 102 is controlled in a one-time discharge mode to detect the total discharge volume of the grain processing device of this application.

[0227] By changing the values ​​of the first discharge port area S, the angle α between the first-stage inner wall surface 103 and the first direction, and the preset time T2, the total discharge volume of the first discharge port 102 is tested. If the difference between the total discharge volume and the user's required discharge volume is within the allowable error range (±20ml), it meets the usage requirements; otherwise, it does not meet the usage requirements.

[0228]

[0229] As can be seen from the table above, for Examples 1-5, the area S of the first discharge port is 700 mm². 2 Satisfying S≥30mm 2 The angle α between the first-stage inner wall surface 103 and the first direction is 32°, satisfying α≥30°, and the preset time T2 satisfies 3s-15s. At this time, the difference between the total discharge volume of the first discharge port 102 and the required discharge volume does not exceed 20ml, which is within the allowable error range. This proves that the grain processing device of this application has a small discharge error, meets the usage requirements, and can achieve precise control of the discharge volume.

[0230] For Comparative Examples 1-5, the area S of the first discharge port is 700 mm². 2 Satisfying S≥30mm 2 The angle α between the first-stage inner wall surface 103 and the first direction is 25°, which does not satisfy α≥30°, while the preset time T2 satisfies 3s-15s. At this time, the difference between the total discharge amount of the first discharge port 102 and the required discharge amount exceeds the allowable error range, resulting in a large error that does not meet the usage requirements.

[0231] The experimental data above shows that when the first discharge port 102 is a one-time discharge method, only when the area S of the first discharge port, the angle α between the first inner wall surface 103 and the first direction, and the preset time T2 meet the requirements of this application and the three parameters work together can they jointly limit the total discharge amount of the opening and closing mechanism, so that the discharge amount meets the user's needs and realizes automatic and precise control of the discharge amount.

[0232] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0233] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
