[0035] 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.

[0036] 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.

[0037] Furthermore, where the term "and / or" appears, "and / or" merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] See Figure 1 As shown, an embodiment of this application provides a rice milling device, which includes a rice milling assembly 200 and a rice discharge assembly 100. The rice milling assembly 200 is used to receive paddy rice from a paddy silo and mill it to obtain rice grains, while the rice discharge assembly 100 is used to discharge the rice grains into a rice container.

[0042] Continue reading Figure 2 and Figure 3 As shown, the rice milling assembly 200 has a rice discharge port 211 for discharging rice grains after the paddy has been milled. The rice discharge assembly 100 includes a slider 110, a sealing member 120, and an elastic member 130. One end of the slider 110 is connected to the sealing member 120 to move the sealing member 120. Both ends of the elastic member 130 are connected to the sealing member 120 and the slider 110, respectively, to provide cushioning against the pressure applied to the slider 110. The sealing member 120 can be at least partially and completely embedded in the rice discharge port 211, and the slider 110 can be controlled to slide relative to the rice milling assembly 200 to close or open the rice discharge port 211.

[0043] For example, in the rice milling state or normal standby state, the sealing member 120 closes the rice discharge port 211 to prevent rice bran and dust from flowing into the rice box. At this time, the elastic member 130 is in a taut state, and the sealing member 120 is in close contact with the end face of the slider 110. In the rice discharge state, the slider 110 moves in a controlled manner, applying a pushing force to the sealing member 120, causing the sealing member 120 to move away from the rice discharge port 211, thereby opening the rice discharge port 211. At the same time, the elastic member 130 changes from a taut state to a relaxed state, and buffers the pushing force of the slider 110, reducing wear and noise during the movement of the sealing member 120.

[0044] Optionally, the elastic element 130 is a coil spring.

[0045] In some embodiments, the sealing member 120 includes a retaining ring 121, which has a semi-cylindrical structure. Under the drive of the slider 110, the retaining ring 121 moves along its own axis to be embedded in or away from the rice discharge port 211.

[0046] For example, the top of the retaining ring 121 is open. After being embedded in the rice discharge opening 211, its two sides fit against the walls of the rice discharge opening 211 to seal it and receive the hulled rice grains. The sliding block 110 moves in a direction parallel to the axis of the retaining ring 121, driving the retaining ring 121 to slide along its own axis. When the retaining ring 121 moves away from the rice discharge opening 211, the rice discharge opening 211 opens, and the rice grains fall into the rice container. When the sliding block 110 returns to its original position, it causes the retaining ring 121 to seal the rice discharge opening 211 again, preventing the leakage of rice bran and dust during the rice milling process.

[0047] In some embodiments, the rice discharge assembly 100 further includes a drive member 140 and a detection member. The drive member 140 is tractively connected to the slider 110 to drive the sealing member 120 to slide relative to the rice discharge port 211. The detection member is installed on the side of the sealing member 120 near the rice discharge port 211 to obtain the weight of the rice grains at the rice discharge port 211. The drive member 140 is electrically connected to the detection member. When the weight of the rice grains at the rice discharge port 211 is greater than a preset value, the drive member 140 drives the retaining ring 121 to open the rice discharge port 211.

[0048] For example, the detection element is a pressure sensor, which is disposed on the side of the sealing element 120 near the rice discharge port 211, thereby enabling the acquisition of the weight of rice grains accumulated at the rice discharge port 211 during the rice milling process. The driving element 140 is a motor, which can controllably drive the slider 110 to move.

[0049] Furthermore, the rice-dispensing assembly 100 also includes a transmission component 180, which includes a gear 181 and a rack 182. The gear 181 is mounted on the output shaft of the drive component 140 so that it can rotate under the drive of the drive component 140. The rack 182 is fixed to the side of the slider 110 and meshes with the slider 110 so that during the rotation of the gear 181, the rack 182 drives the slider 110 to move in a straight line.

[0050] Of course, in other embodiments, the transmission component 180 may also be a chain drive, belt drive, or other working component, and no specific limitation is made here.

[0051] In some embodiments, the sealing member 120 further includes a gate 122, a retaining ring 121 fixed to the side of the gate 122 near the slider 110, and the slider 110 is connected to the gate 122. The rice milling assembly 200 includes a bracket 210, and a through groove 212 is opened at one end of the bracket 210 where the rice discharge port 211 is located, and the gate 122 passes through the through groove 212.

[0052] For example, the gate 122 is a flat plate with a retaining ring 121 on one side abutting against the slider 110 to serve as the force-bearing part of the sealing member 120. One end of the elastic member 130 is connected to the gate 122, and the other end is connected to the side of the slider 110, so that under the tension of the elastic member 130, the gate 122 always fits against the slider 110, ensuring smooth movement of the gate 122 and reducing noise. The end of the bracket 210 with the rice discharge port 211 is fixed to the housing of the rice milling equipment to install the rice milling assembly 200 and the rice discharge assembly 100 inside the housing. By opening a through groove 212 at the end of the bracket 210 with the rice discharge port 211, the movement space of the gate 122 is provided, and the range of motion of the sealing member 120 is now within the bracket 210, simplifying the design structure of the rice discharge mechanism and reducing the overall installation volume.

[0053] The rice milling equipment sets a reasonable threshold based on the rice milling capacity of the rice milling component 200. The rice milling equipment obtains the weight of the rice grains accumulated at the rice discharge port 211 through a pressure sensor to determine whether the threshold for opening the sealing component 120 has been reached.

[0054] See Figure 3 and Figure 4 As shown, when the weight of the rice grains reaches a set threshold, a high-level signal is transmitted to the drive unit 140 via the MCU (Microcontroller Unit). The drive unit 140 rotates counterclockwise, which drives the rack 182 and the slider 110 to move via the gear 181. The slider 110 pushes the baffle 122 to move, while the elastic element 130 changes from a taut state to a relaxed state, providing a buffer against the pushing force of the slider 110 and ensuring the stable operation of the baffle 122. At this time, the baffle ring 121 disengages from the rice discharge port 211, the rice discharge port 211 is opened, and the rice grains fall into the rice box.

[0055] See Figure 5 and Figure 6 As shown, when the weight is detected to be below the threshold, a low-level signal is transmitted to the drive unit 140 via the MCU. The drive unit 140 rotates clockwise to control the slider 110 to reset. Under the tension of the spring, the gate 122 moves with the slider 110 and causes the retaining ring 121 to block the rice discharge port 211.

[0056] Furthermore, the slider 110 abuts against both ends of the gate 122, and two elastic elements 130 are also provided accordingly. The two elastic elements 130 are arranged opposite to each other on both sides of the slider 110 to ensure that the running amount on both sides of the gate 122 is the same and to ensure that the gate 122 runs smoothly.

[0057] See again Figure 3 and Figure 5 As shown, in some embodiments, the rice milling assembly 200 further includes a screen 220, which is cylindrical and fixed to the end of the support 210 away from the rice discharge port 211. The axis of the screen 220 is inclined relative to the horizontal plane, and the axis of the retaining ring 121 is parallel to the axis of the screen 220.

[0058] For example, the screen 220 is equipped with a screw inside, so that after the paddy enters the screen 220, the paddy is squeezed by the screw and the wall of the screen 220 to dehull it into rice grains, thus achieving the milling and dehulling of the paddy. The screw is parallel to the axis of the screen 220 so that it synchronously drives the rice grains upward during the milling process. During the upward process, the rice grains are milled multiple times to form refined rice, improving the milling quality of the rice grains. During the milling process, the bran dust falls into the bran box through the screen holes of the screen 220 under the action of gravity, while the rice grains flow back to the rice discharge port 211 and accumulate after reaching the top of the screen 220.

[0059] In this embodiment, the sliding direction of the sealing member 120 is set parallel to the axis of the screen 220, so that when the sealing member 120 opens the rice discharge port 211, the slider 110 pushes the gate 122 in a downward tilting direction. The gravity of the gate 122 itself can provide the potential energy for downward movement, further accelerating the opening speed of the sealing member 120.

[0060] In some embodiments, the angle between the axis of the screen 220 and the horizontal plane is less than or equal to 30°.

[0061] For example, the axis of the screen 220 forms an angle α with the horizontal plane. The angle α can be 5°, 10°, 15°, 20°, 25°, 30°, etc., and can be selected according to actual needs. In this way, the problem of excessive tilt angle of the screen 220, excessive pressure on the screw to drive the rice upward, and some rice not being able to follow the screw upward can be avoided, thus ensuring the milling accuracy of the rice.

[0062] Continue reading Figure 2 and Figure 7 As shown, in some embodiments, the rice milling assembly 100 further includes a fixing plate 150 and a limiting member 160. The fixing plate 150 is mounted on the rice milling assembly 200 and slidably connected to the slider 110. The slider 110 has a groove 111, and the limiting member 160 is mounted on the fixing plate 150 and passes through the groove 111.

[0063] For example, the drive component 140 is mounted on the fixed plate 150, and the fixed plate 150 is fixedly connected to the top surface of the bracket 210 to mount the rice discharge assembly 100 onto the rice milling assembly 200. The slider 110 is mounted on the side of the fixed block away from the bracket 210 and can slide relative to the fixed plate 150. A U-shaped groove 111 is provided in the middle of the side of the slider 110 away from the gate 122, and the limiting component 160 is fixed to the middle of the fixed plate 150 and passes through the groove 111. By limiting the slider 110 and the groove 111, the slider 110 can only move along the extension direction of the groove 111, realizing the motion guidance of the slider 110, ensuring that the running direction of the slider 110 does not deviate, thereby improving the control accuracy of the sealing component 120. When the limiting member 160 abuts against the end of the slide groove 111, it can be determined that the slider 110 has been completely reset. At this time, the retaining ring 121 completely blocks the rice discharge port 211, avoiding the problem of rice husk leakage caused by the retaining ring 121 not being properly sealed.

[0064] Furthermore, the limiting member 160 includes a bolt 161 and a washer 162. The bolt 161 passes sequentially through the slide groove 111 of the slider 110 and the fixing plate 150 before locking with the bracket 210 to fix the fixing plate 150 to the bracket 210 and guide it in conjunction with the slide groove 111. The bolt 161 passes through the washer 162, and the washer 162 is embedded in the slide groove 111 to enhance the fixing effect between the fixing plate 150 and the bracket 210 and the sliding guidance of the slider 110.

[0065] Furthermore, one of the fixing plate 150 and the bracket 210 is provided with a positioning groove, and the other is provided with a positioning pin, so that during the installation of the fixing plate 150 and the bracket 210, the positioning groove and the positioning pin are engaged to achieve the initial positioning of the fixing plate 150 and ensure the installation accuracy of the fixing plate 150.

[0066] Continue reading Figure 8 As shown, in some embodiments, the rice discharge assembly 100 also includes a micro switch 170, which is mounted on the fixed plate 150. The slider 110 is provided with a contact portion 112. When the retaining ring 121 is fully embedded in the rice discharge port 211, the contact portion 112 abuts against the micro switch 170.

[0067] For example, the contact portion 112 protrudes from the side of the slider 110, and the micro switch 170 has an actuating spring, which is located on the movement stroke of the contact portion 112. When the contact portion 112 acts on the actuating spring, when the spring displacement reaches a critical point, a momentary action is generated, causing the contacts to quickly connect or disconnect, thereby determining the current operating status of the rice milling equipment. Thus, when the slider 110 is controlled to open the rice discharge port 211, the contact portion 112 separates from the micro switch 170, and the rice milling equipment system determines that it is currently in the rice discharge state. When the slider 110 is controlled to close the rice discharge port 211, the contact portion 112 moves towards the micro switch 170. When the contact portion 112 contacts the micro switch 170, the rice milling equipment system determines that the retaining ring 121 is fully in place, the rice discharge port 211 is blocked, and the next rice milling operation can proceed. If the contact part 112 does not contact the micro switch 170, it is determined that the current retaining ring 121 has not been successfully reset, and there may be a gap in the rice discharge port 211. This application achieves precise control of the rice discharge port 211 by setting the contact part 112 and the micro switch 170, thereby ensuring the rice milling quality of the rice milling equipment.

[0068] Continue reading Figure 9 As shown, in some embodiments, the rice milling assembly 200 further includes a diverter 230, which is installed below the rice discharge port 211 along the direction of gravity. The diverter 230 includes a plurality of diverting holes 231, and each diverting hole 231 communicates with the rice discharge port 211 when the retaining ring 121 opens the rice discharge port 211.

[0069] For example, the diverter 230 is fixed to the bottom of the bracket 210 and has a plurality of diverter holes 231 communicating with the rice discharge port 211. The rice box is disposed on the bottom side of the diverter 230 so that when the rice discharge port 211 is opened, the rice grains are discharged through the rice discharge port 211. After the rice grains are dispersed by each diverter hole 231, the rice grains flow into the rice box, avoiding the accumulation of rice grains that would cause the rice discharge port 211 to be blocked.

[0070] Optionally, the number of diversion holes 231 can be two, three, four, etc., which can be reasonably set according to actual needs, and there is no specific restriction.

[0071] In some embodiments, the flow area of ​​each diversion hole 231 increases sequentially in the direction away from the rice discharge port 211.

[0072] For example, the diversion hole 231 has a Λ-shaped structure so that the flow area of ​​the rice grains increases sequentially, which facilitates the rapid discharge of rice grains and improves the rice discharge rate.

[0073] 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.

[0074] The embodiments described above are merely illustrative of 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.
