Description

Technical Field

[0001] This invention relates to the technical field of agricultural machinery, specifically to a grinding equipment, grinding control method, and control device. Background Technology

[0002] Some agricultural products often require the removal of their outer skin during processing to ensure better taste. Traditionally, this is done using a mill to separate the skin from the kernel. However, agricultural products, such as brown rice and beans, are not perfectly round; they are often oval or rhomboid in shape, with long and short sides. During milling, the product flips over. When the long sides flip to face the milling surfaces, the contact between the milling surfaces and the product is more intense, resulting in greater milling force. Conversely, when the short sides flip to face the milling surfaces, the contact force is relatively less intense. This uneven milling force affects the overall milling effect. Summary of the Invention

[0047] The milling equipment provided by this invention includes a frame and a milling mechanism. The milling mechanism includes a turning belt and a milling belt arranged at relative intervals, forming a milling area between them. When agricultural products (such as brown rice) are conveyed into the milling area, the brown rice is milled by the combined milling action of the turning belt and the milling belt. Furthermore, the hardness of the turning belt is set to be less than that of the milling belt, and the turning belt is made of an elastic material while the milling belt is made of a rigid material. During the milling of the brown rice... Because the turning belt is elastic, when the longer side of the brown rice is placed between the turning belt and the grinding belt, the turning belt can undergo elastic deformation under the pressure of the brown rice without damaging the brown rice. When the shorter side of the brown rice is placed between the turning belt and the grinding belt, the turning belt and the grinding belt can also make good contact with the brown rice to ensure better grinding effect. Moreover, the grinding belt has relatively high hardness, thus ensuring better grinding strength and stability, resulting in a longer service life of the grinding equipment and better quality of the finished product.

Detailed Implementation

[0064] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0065] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0066] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0067] This invention provides a grinding device 100, which can be used to grind agricultural products to remove the skin from the surface of the products, resulting in a better taste when consumed. Specifically, the grinding device 100 can grind agricultural products such as brown rice and beans. For ease of explanation, the following description mainly uses brown rice as an example; other products can be adapted accordingly.

[0068] Specifically, please refer to Figures 1 to 3 The grinding equipment 100 includes a frame 1 and a grinding mechanism 2 disposed on the frame 1. The grinding mechanism 2 includes a turning belt 21 and a grinding belt 22 arranged at relative intervals along the vertical direction of the frame 1, and the interval between the turning belt 21 and the grinding belt 22 forms a grinding area. The hardness of the turning belt 21 is less than that of the grinding belt 22, and the material of the turning belt 21 is an elastic material, while the material of the grinding belt 22 is a rigid material.

[0069] In this invention, after the brown rice is conveyed to the milling area, it can be milled by the combined milling action of the turning belt 21 and the milling belt 22. Furthermore, the hardness of the turning belt 21 is set to be less than that of the milling belt 22, and the turning belt 21 is made of an elastic material while the milling belt 22 is made of a rigid material. During the milling of the brown rice, because the turning belt 21 is elastic, the longer side of the brown rice stands upright on the turning belt 21 and the milling belt 22. When the grinding belts 22 are in contact with each other, the turning belt 21 can undergo elastic deformation under the pressure of the brown rice without damaging the brown rice. When the shorter side of the brown rice is placed between the turning belt 21 and the grinding belt 22, the turning belt 21 and the grinding belt 22 can also make good contact with the brown rice to ensure a better grinding effect. Moreover, the grinding belt 22 has relatively high hardness, thus ensuring better grinding strength and stability, resulting in a longer service life of the grinding equipment 100 and better quality of the finished product.

[0070] Preferably, the turning belt 21 is made of high-density sponge, where the sponge weighs at least 25 kg per cubic meter. Due to its good hardness and elasticity, the high-density sponge provides good soft contact, and its high surface friction helps to better turn the brown rice, ensuring uniform milling throughout. Alternatively, the milling belt 22 includes multiple milling plates arranged in parallel. These multiple milling plates form a milling surface, working together with the turning belt 21 to mill the brown rice, resulting in greater milling force and better milling effect. Furthermore, once one milling plate wears out, it can be replaced promptly without replacing all of them, making maintenance easier and reducing operating costs. Compared to traditional milling belts that are prone to deviation during operation, using milling plates makes the milling process more stable and extends its service life.

[0071] Since agricultural products vary in size depending on their type, the spacing between the turning belt 21 and the grinding belt 22 in this invention is adjustable to meet the grinding requirements of different products. It is understood that at least one of the turning belt 21 and the grinding belt 22 can be configured to move closer to or further away from each other.

[0072] Preferably, combined with Figures 2 to 4 As shown, the turning belt 21 has a vertical travel distance along the frame 1. By moving the turning belt 21 along the frame 1 in the vertical direction, the distance between the turning belt 21 and the grinding belt 22 can be adjusted to match the processing needs of different agricultural products. The grinding mechanism 2 also includes a first conveying component 23 and a turning drive structure 24 connected to the first conveying component 23. The turning belt 21 is disposed on the first conveying component 23, and the turning drive structure 24 drives the first conveying component 23 to move along the frame 1 in the vertical direction, thereby causing the turning belt 21 to move along the frame 1 in the vertical direction, thus adjusting the size of the grinding area.

[0073] Furthermore, such as Figure 2 and Figure 9As shown, the first conveying component 23 includes a conveying bracket 231, a first driving roller 232, a first driven roller 233, and a first driver 234. The conveying bracket 231 is slidably mounted on the frame 1 in the vertical direction and is connected to the material turning drive structure 24. Specifically, a slide rail extending in the vertical direction is provided on the frame 1, and a slider is provided on the conveying bracket 231. The slider is housed within the slide rail and can slide up and down along the slide rail. The first driving roller 232 is rotatably mounted on the conveying bracket 231, and the first driven roller 233 is rotatably mounted on the conveying bracket 231. The first driven roller 233 and the first driving roller 232 are arranged parallel to each other in the transverse direction of the frame 1. The material turning belt 21 is sleeved on the first driving roller 232 and the first driven roller 233. The first driver 234 is mounted on the conveying bracket 231 and connected to the first driving roller 232, and is used to drive the first driving roller 232 to rotate. The first driver 234 drives the first active roller 232 to rotate, which in turn moves the turning belt 21 sleeved on the outer periphery of the first active roller 232, and the turning belt 21 drives the first driven roller 233 to rotate. The turning drive structure 24 drives the conveying bracket 231 to move along the vertical direction of the frame 1, thereby moving the first active roller 232, the first driven roller 233, the first driver 234, and the turning belt 21 together along the vertical direction of the frame 1 to adjust the distance between the turning belt 21 and the grinding belt 22.

[0074] Furthermore, combined Figure 2 and Figure 3 As shown, the material turning drive structure 24 includes a second driver 241, a first transmission gear 242, a second transmission gear 243, a transmission screw 244, a transmission nut 245, and a transmission frame 246. The second driver 241 is mounted on the frame 1, specifically, the second driver 241 is mounted on the top of the frame 1. The second driver 241 can be configured as a second drive motor, and the drive shaft of the second drive motor extends along the vertical direction of the frame 1. The first transmission gear 242 is connected to the second driver 241, specifically, the first transmission gear 242 and the drive shaft of the second drive motor are coaxially connected. The second transmission gear 243 meshes with the first transmission gear 242, and the diameter of the second transmission gear 243 is larger than the diameter of the first transmission gear 242, which can achieve speed reduction; the transmission screw 244 is coaxially connected to the second transmission gear 243 and extends along the vertical direction of the frame 1; the transmission nut 245 is screwed to the transmission screw 244; the transmission frame 246 is connected to the transmission bracket 231, and the transmission nut 245 is disposed on the transmission frame 246.

[0075] The second driver 241 drives the first transmission gear 242 to rotate, which in turn drives the second transmission gear 243 to rotate. This causes the transmission screw 244 and the second transmission gear 243 to rotate together, allowing the transmission nut 245 screwed onto the transmission screw 244 to move along the transmission screw 244. In other words, the transmission nut 245 can move along the vertical direction of the frame 1, thereby driving the transmission frame 246 connected to the transmission nut 245 to move along the vertical direction of the frame 1. This, in turn, drives the conveyor bracket 231 to move along the vertical direction of the frame 1, allowing the entire first conveyor component 23 to move along the vertical direction of the frame 1. This adjusts the material turning belt 21 to move closer to or further away from the grinding belt 22, making the grinding area more adaptable to different agricultural products and improving the grinding effect.

[0076] Furthermore, the grinding mechanism 2 also includes a second conveying component 25 disposed on the frame 1, the second conveying component 25 being connected to the grinding belt 22, thereby realizing the conveying movement of the grinding belt 22. Preferably, combined with Figure 2 and Figure 3 As shown, the second conveying component 25 includes a third driver 251, a second driving roller 252, two driving sprockets 254, a second driven roller 253, two driven sprockets 255, and two conveying chains 256. The third driver 251 is mounted on the frame 1. Preferably, the third driver 251 can be configured as a third drive motor. The second driving roller 252 is rotatably mounted on the frame 1 and connected to the third driver 251. Specifically, the third drive motor and the second driving roller 252 can be driven by a belt. The two driving sprockets 254... 54 are respectively disposed at both ends of the second driving roller 252; the second driven roller 253 is rotatably disposed on the frame 1; two driven sprockets 255 are respectively disposed at both ends of the second driven roller 253; two conveyor chains 256 are respectively sleeved on one of the corresponding driving sprockets 254 and one of the driven sprockets 255, the two conveyor chains 256 are arranged in parallel and both extend laterally along the frame 1; both ends of each grinding sand plate are respectively disposed on the two conveyor chains 256, and multiple grinding sand plates are arranged side by side along their conveying direction. The second drive roller 252 is driven to rotate by the third driver 251. The second drive roller 252 can drive the two drive sprockets 254 to rotate, thereby driving the two conveyor chains 256 to move, so as to drive the two driven sprockets 255 to rotate, and drive the second driven roller 253 to rotate, so that the multiple grinding plates located on the two conveyor chains 256 can move laterally along the frame 1 in sequence to convey and grind the brown rice placed on it.

[0077] It should be noted that the aforementioned "lateral" refers to the left-right direction of the frame 1 when the milling equipment 100 is operating normally. That is, when the milling equipment 100 is operating normally, the first driving roller 232 and the first driven roller 233 are spaced apart along the left-right direction of the frame 1, and the second driving roller 252 and the second driven roller 253 are also spaced apart along the left-right direction of the frame 1. In other words, both conveyor chains 256 extend along the left-right direction of the frame 1, allowing both the turning belt 21 and the milling belt 22 to convey materials along the left-right direction of the frame 1. The "longitudinal" refers to the direction perpendicular to the lateral direction in the horizontal direction. For example, if the lateral direction refers to the left-right direction, then the longitudinal direction is the front-back direction. Unless otherwise specified, all descriptions of orientation in this invention shall be taken as such. Preferably, when the milling equipment 100 is operating, the conveying speed of the milling belt 22 is greater than the conveying speed of the turning belt 21, so that after milling, the brown rice can be conveyed from the right side of the milling belt 22 for collection.

[0078] Moreover, such as Figure 4 As shown, the second conveying component 25 further includes a support plate 257 disposed on the frame 1. The support plate 257 is located between the intervals of the two conveying chains 256 and on the side of the two conveying chains 256 facing the turning belt 21. The support plate 257 is flat in at least the area corresponding to the turning belt 21. Each of the grinding plates is generally square in shape, and there will be a certain gap between two adjacent grinding plates, especially in the arc-shaped area, where the gap between two adjacent grinding plates will increase, thereby affecting the grinding effect. Therefore, by providing a support plate 257 corresponding to the grinding area, and by providing a flat plate 257 in the corresponding grinding area and by providing a horizontal orientation, the multiple grinding plates can be arranged more closely when moving to the grinding area, and can move better in the horizontal direction. The brown rice is less likely to fall into the gap between two adjacent grinding plates during grinding, thereby ensuring a better grinding effect.

[0079] The grinding equipment 100 further includes a tensioning mechanism 9, which is mounted on the frame 1 and used to adjust the tension of the two conveyor chains 256. Specifically, in conjunction with... Figures 3 to 5As shown, the tensioning mechanism 9 includes a first tensioning rod 91, a second tensioning rod 92, a tension adjusting gear set, and a telescopic rod 94. The first tensioning rod 91 comprises two parallel first tensioning rods 91, with their first ends connected to the frame 1 and their second ends rotatably connected to the second tensioning rod 92. The tension adjusting gear set includes two tensioning gears 93, each rotatably mounted at one end of the second tensioning rod 92 and engaging with one of the two conveyor chains 256. One end of the telescopic rod 94 is hinged to the frame 1, and the other end is hinged to the middle of the two first tensioning rods 91. Under the weight of the tensioning mechanism 9, it presses against the two conveyor chains 256, keeping them constantly taut and thus increasing conveying efficiency.

[0080] In this invention, the milling device 100 further includes a feeding mechanism 4, which is located at one end of the milling belt 22. Preferably, the milling belt 22 is configured to move in a left-to-right direction, and the discharge port of the feeding mechanism 4 is located at the left end of the milling belt 22, so that brown rice can fall onto the milling belt 22 and be conveyed from left to right to enter the milling area. After milling, the rice is output from the right end of the milling belt 22.

[0081] Preferably, combined with Figure 2 and Figure 11 As shown, the feeding mechanism 4 includes a feeding hopper 41, an adjusting plate 42, a feeding drive motor 43, a feeding synchronous pulley set 44, and a feeding uniform shaft 45. The feeding hopper 41 is fixedly mounted on the frame 1. The adjusting plate 42 is attached to the inner wall of the feeding hopper 41 and has a stroke that can move up and down along its inner wall. The feeding uniform shaft 45 is rotatably mounted on the feeding hopper 41 and is located near the discharge port of the feeding hopper 41. The feeding drive motor 43 is mounted on the frame 1 and drives the feeding uniform shaft 45 to rotate through the feeding synchronous pulley set 44 to achieve uniform material discharge. The feeding outlet adjusting plate 42 can adjust the opening size of the discharge port of the feeding hopper 41 to adjust the discharge flow rate, thereby better controlling the grinding speed and grinding effect.

[0082] Moreover, combined Figure 2 , Figure 7 and Figure 8As shown, the milling equipment 100 also includes a discharge mechanism 3, which includes a discharge hopper 31 and a guide plate 32. The inlet of the discharge hopper 31 is arranged facing the conveying end of the milling belt 22. A first discharge channel and a second discharge channel are formed inside the discharge hopper 31. The guide plate 32 is movably disposed inside the discharge hopper 31 and has a first working position and a second working position. When the guide plate 32 is in the first working position, the first discharge channel is connected to the inlet of the discharge hopper 31, and the second discharge channel is blocked from the inlet of the discharge hopper 31, so that the milled rice can be better collected. When the guide plate 32 is in the second working position, the second discharge channel and the inlet of the discharge hopper 31 are connected, and the first discharge channel and the inlet of the discharge hopper 31 are blocked, so that the milled rice can flow out from the second discharge channel, thereby collecting milled rice samples to facilitate the testing of the milled samples and timely understanding of the milling effect.

[0083] It is understood that the guide plate 32 can be manually switched or driven by a drive component. Preferably, the discharge mechanism 3 further includes a guide drive structure. The guide plate 32 is rotatably mounted on the discharge hopper 31. The guide drive structure is mounted on the frame 1 and connected to the guide plate 32. The guide drive structure drives the guide plate 32 to rotate, thereby realizing the automatic switching of the guide plate 32 and making the grinding equipment 100 more automated.

[0084] The milling equipment 100 further includes a sample detection mechanism 5 and a feeding mechanism 6 mounted on the frame 1. The feeding mechanism 6 is configured to correspond to the second discharge channel of the discharge hopper 31. The polished rice flowing out from the second discharge channel can fall onto the feeding mechanism 6 and be conveyed to the sample detection mechanism 5. The sample detection mechanism 5 detects the polished rice sample on the feeding mechanism 6 to detect the broken rice rate of the polished rice and thus determine the milling quality.

[0085] Preferably, such as Figure 6As shown, the feeding mechanism 6 includes an active conveying roller 61 and a driven conveying roller 62 rotatably mounted on the frame 1, a conveyor belt 63 sleeved between the active conveying roller 61 and the driven conveying roller 62, and a fourth driver 64 connected to the active conveying roller 61. The fourth driver 64 drives the active conveying roller 61 to rotate, thereby moving the conveyor belt 63 and causing the driven conveying roller 62 to rotate as well, conveying the polished rice that falls onto the conveyor belt 63 from the second conveying channel. The conveyor belt 63 conveys rice from right to left along the frame 1, placing the feeding mechanism 6 below the second conveying component 25, resulting in a more compact structure and a smaller overall size of the milling equipment 100.

[0086] Preferably, combined with Figure 10 As shown, the sample detection mechanism 5 includes a detection camera 51, a supplementary light 52, and a spreading plate 53. The spreading plate 53 is located above the conveyor belt 63 and is spaced apart from the conveyor belt 63. Preferably, the distance between the spreading plate 53 and the conveyor belt 63 is the thickness of a layer of polished rice. The spreading plate 53 is located near the outlet of the second conveying channel. The spreading plate 53 can spread the polished rice flowing out of the second conveying channel to ensure that the polished rice entering the detection area of ​​the detection camera 51 does not pile up, ensuring a more accurate detection effect. The spreading plate 53 is unidirectionally rotatable, so that the rice grains move from the discharge mechanism 3 toward the detection camera 51, while if they move in the opposite direction, the rice grains cannot pass through the spreading plate 53. The supplementary light 52 is used for illumination. Then, under the conveying action of the conveyor belt 63, the flat rice grains can enter the detection field of view of the detection camera 51. The detection camera 51 can obtain image information of the polished rice on the conveyor belt 63. The broken rice rate of the milled rice can be judged by the image information, and then the milling effect of the milling equipment 100 can be judged.

[0087] If the broken rice rate is too high, it indicates that the grinding force is too great. This can be reduced by increasing the distance between the turning belt 21 and the grinding belt 22; alternatively, the grinding force can be reduced by decreasing the conveying speed of either the turning belt 21 or the grinding belt 22. After adjustment, another sample of polished rice can be collected to obtain image information, and the broken rice rate can be detected again until it reaches the preset range.

[0088] In addition, combined Figure 2 and Figure 10As shown, the grinding equipment 100 also includes a slag removal mechanism 7, which is located below the second conveying section and on the left side of the conveyor belt 63. The slag removal mechanism 7 is used to remove the slag adhering to the grinding belt 22 after grinding, so as to maintain the cleanliness of the grinding belt 22 and ensure the grinding effect of the grinding belt 22.

[0089] Specifically, such as Figure 10 As shown, the slag removal mechanism 7 includes a blowing structure 71 and a suction structure 72. The blowing structure 71 includes a blowing nozzle and a blowing device connected to the blowing nozzle. The suction structure 72 includes a suction hopper and a suction device connected to the suction hopper. The blowing port of the blowing nozzle is positioned towards the grinding belt 22, and the inlet of the suction hopper is positioned towards the blowing port of the blowing nozzle. Preferably, the suction hopper is located to the left of the blowing nozzle, and the lower part of the grinding belt 22 is in a state of conveying from right to left. Thus, the blowing port of the blowing nozzle is positioned towards the conveying direction of the grinding belt 22 to better blow off the slag attached to the grinding belt 22 and allow it to enter the suction hopper.

[0090] Moreover, the blowing device and the suction device can be integrated into one unit. The outlet end of the suction device is connected to the blowing nozzle, and the inlet end of the suction device is connected to the suction hopper. Therefore, the material can be blown out and recycled at the same time, resulting in a simpler structure and lower cost.

[0091] In addition, the milling equipment 100 may also include a control device 1000. The control device 1000 is electrically connected to the first driver 234, the second driver 241, the third driver 251, the fourth driver 64, the material guiding drive structure, and the detection camera 51. According to the detection structure of the detection camera 51, the control device 1000 can control the first driver 234, the second driver 241, the third driver 251, the fourth driver 64, and the material guiding drive structure to adjust the broken rice rate to within the acceptable range. This makes the milling equipment 100 more automated and more sensitive in adjustment, thereby improving the rice milling effect.

[0092] Furthermore, the milling equipment 100 also includes a temperature detection mechanism 8, which is located at the conveying end of the milling belt 22 and is used to detect the temperature of the polished rice on the milling belt 22. The temperature detection mechanism 8 is electrically connected to the control device 1000, and the milling performance is determined based on the temperature value detected by the temperature detection mechanism 8. For example, if the temperature value detected by the temperature detection mechanism 8 is too high, it indicates that the milling force is too large. Therefore, the control device 1000 can adjust the operation of the second driver 241, so that the turning belt 21 can move away from the milling belt 22, thereby increasing the distance between the turning belt 21 and the milling belt 22, reducing the milling force, and making the milling force more moderate. Conversely, if the temperature detected by the temperature detection mechanism 8 is too low, it indicates that the grinding force is too weak. Similarly, the second driver 241 can be adjusted by the control device to move the turning belt 21 closer to the grinding belt 22, thereby reducing the distance between the turning belt 21 and the grinding belt 22, increasing the grinding force, making the grinding force more moderate, and improving the rice yield. Alternatively, the conveying speed of the grinding belt 22 and the turning belt 21 can be increased, which can also increase the grinding force, thereby improving the rice yield and grinding efficiency.

[0093] For details, please refer to Figure 12 The control device 1000 of the grinding equipment 100 may include: a processor 1001, such as a CPU, a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen, an input unit such as a keyboard, and buttons; optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 1005 may be a high-speed RAM or a stable, non-volatile memory, such as a disk drive. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0094] Those skilled in the art will understand that Figure 12 The structure of the control device 1000 shown does not constitute a limitation on the control device 1000. It may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0095] like Figure 12As shown, the memory 1005, which serves as a computer storage medium, may include an operating system, a network communication module, a user interface module, and the control program for the grinding equipment 100.

[0096] exist Figure 12 In the control device 1000 shown, the processor 1001 calls the control program of the grinding equipment 100 stored in the memory 1005 and performs the following operations:

[0097] Upon receiving the power-on command, the guide plate 32 of the discharge mechanism 3 is controlled to be in the first working position;

[0098] At preset intervals, the guide plate 32 of the discharge mechanism 3 is switched to the second working position to obtain the test sample and detect the breakage rate of the sample.

[0099] The spacing between the turning belt 21 and the grinding belt 22 is controlled according to the material breakage rate, and / or the conveying speed of the turning belt 21 and / or the conveying speed of the grinding belt 22 is controlled according to the material breakage rate.

[0100] Furthermore, the processor 1001 calls the control program of the grinding device 100 stored in the memory 1005 and performs the following operations:

[0101] After receiving the power-on command and controlling the guide plate 32 of the discharge mechanism 3 to be in the first working position, the method further includes:

[0102] Obtain the real-time temperature of the conveying end of the grinding belt 22;

[0103] Based on the real-time temperature, the spacing between the turning belt 21 and the grinding belt 22 is controlled, and / or the conveying speed of the turning belt 21 and / or the conveying speed of the grinding belt 22 is controlled.

[0104] In conjunction with the aforementioned hardware facilities, this invention also provides a grinding control method, such as... Figure 13 As shown, the milling control method includes the following steps:

[0105] S100: Receive the power-on command and control the guide plate 32 of the discharge mechanism 3 to be in the first working position;

[0106] S200: At preset intervals, control the guide plate 32 of the discharge mechanism 3 to switch to the second working position, acquire the test sample, and detect the breakage rate of the sample;

[0107] S300, Adjust the spacing between the turning belt 21 and the grinding belt 22 according to the broken material ratio, and / or adjust the conveying speed of the turning belt 21 and / or the conveying speed of the grinding belt 22 according to the broken material ratio.

[0108] It should be noted that receiving a power-on command means that the grinding equipment 100 may be equipped with a power-on button, or the grinding equipment 100 may be equipped with an operation screen with a power-on button, or the grinding equipment 100 may be powered on via voice control, or the grinding equipment 100 may be powered on via a remote terminal (such as a mobile phone, tablet or computer). There are many ways to power on, which will not be listed here.

[0109] When the milling equipment 100 is started, the guide plate 32 of the discharge mechanism 3 automatically moves to the first working position, ensuring that the milled rice can flow out from the first discharge channel at the beginning. After the milling equipment 100 has been working for a period of time, its operation enters a stable state, and then the guide plate 32 is controlled to switch working positions to sample the milled rice, ensuring the quality of the finished milled product.

[0110] The preset interval time can be adjusted according to user needs. For example, sampling can be performed every 5 to 20 minutes, with each sampling lasting 2 to 3 minutes. This allows for a clearer and more intuitive understanding of the working status of the grinding equipment 100 during operation. If the grinding effect is not ideal, the equipment can be adjusted in a timely manner to ensure that the grinding equipment 100 is always in the best grinding state.

[0111] Specifically, the broken rice rate refers to the percentage of broken rice grains among the rice grains separated after brown rice has passed through the turning belt 21 and the milling belt 22. A higher broken rice rate indicates more broken rice grains and thus more wasted rice grains. When the broken rice rate is detected to be outside the preset range, the control device can adjust the operation of the first driver 234, the second driver 241, or the third driver 251 according to the broken rice rate to adjust the distance between the turning belt 21 and the milling belt 22, and / or adjust the conveying speed of the turning belt 21 and / or the conveying speed of the milling belt 22. Preferably, when an abnormal broken rice rate is detected, the distance between the turning belt 21 and the milling belt 22 can be adjusted first to reduce the positive pressure applied to the rice grains, and then the speeds of the turning belt 21 and the milling belt 22 can be finely adjusted to optimize the milling effect.

[0112] Specifically, when the broken rice rate is high, it indicates that the grinding force is too great. The control device can control the second driver 241 to operate, causing the turning belt 21 to move away from the grinding belt 22, increasing the distance between the turning belt 21 and the grinding belt 22, and reducing the grinding force. Alternatively, the control device can reduce the output speed of the first driver 234 and / or the second driver 241 to reduce the conveying speed of the turning belt 21 and / or the grinding belt 22, thereby reducing the grinding force, reducing the broken rice rate, and improving the grinding effect.

[0113] When the broken rice rate is less than the preset broken rice rate, and the milling loss rate (also known as the bran removal rate, which refers to the percentage reduction in volume and weight of brown rice due to the loss of the bran and germ during the milling process) is low, meaning that less bran powder is milled from the surface of the brown rice, it indicates that only a small amount of brown rice is milled, while the majority remains brown rice. This also indicates that the milling effect of the milling equipment 100 is poor. In this case, the control device can control the second driver 241 to move the turning belt 21 towards the milling belt 22, thereby reducing the distance between the turning belt 21 and the milling belt 22, increasing the milling force, and improving the milling effect of the brown rice. Alternatively, the control device can increase the output speed of the first driver 234 and / or the second driver 241 to increase the conveying speed of the turning belt 21 and / or the milling belt 22, increasing the milling force, resulting in a higher milling rate of brown rice, and thus improving the milling effect of the brown rice.

[0114] Furthermore, when the grinding mechanism 2 further includes a temperature detection mechanism 8 corresponding to the conveying end of the grinding belt 22, after step S100 above, the following is also included:

[0115] S110. Obtain the real-time temperature of the conveying end of the grinding belt 22;

[0116] S120. Adjust the conveying speed of the turning belt 21 and / or the conveying speed of the grinding belt 22 according to the real-time temperature.

[0117] The temperature detection mechanism 8 can be mounted on the frame 1 or fixed to other mechanisms, with its detection field of view facing the conveying end of the grinding belt 22. The temperature detection mechanism 8 can obtain the real-time temperature of the ground rice grains, allowing for the assessment of the grinding effect based on this real-time temperature.

[0118] Specifically, since brown rice milling typically involves four or more milling processes, if the temperature of the rice grains flowing out of the mill is too high in the first few milling processes, the breakage rate of the rice grains in subsequent milling processes will increase significantly, affecting the milling effect. Therefore, the temperature detection mechanism 8 can monitor the temperature of the rice grains flowing out of the mill in real time. When the temperature is too high, the conveying speed of the turning belt 21 and the milling belt 22 can be adjusted to ensure better finished product results. Understandably, the higher the conveying speed of the turning belt 21 and the milling belt 22, the greater the milling friction, resulting in higher milling efficiency. However, the collision between the brown rice and the turning belt 21 and the milling belt 22 will also be more intense, thus causing the rice grain temperature to rise. Therefore, when the detected real-time temperature exceeds the preset value, the conveying speed of the turning belt 21 and / or the milling belt 22 should be appropriately reduced to reduce the collision between the brown rice and the turning belt 21 and the milling belt 22, reduce the temperature of the rice grains flowing out of the mill, thereby avoiding excessive broken rice rate, ensuring milling quality, and better ensuring the germ retention rate of rice grains and the nutrition of rice grains.

[0119] The grinding equipment 100 may be equipped with a display device to show the real-time operating status of the grinding equipment 100, facilitating observation and operation by the operator. Specifically, the display device may be a screen that displays the real-time temperature value detected by the temperature detection mechanism 8, as well as parameters such as the real-time rotational speeds of the first driver 234, the second driver 241, and the third driver 251, thereby providing the operator with a more intuitive understanding of the operating status of the grinding equipment 100.

[0120] This grinding control method enables automated grinding production of the grinding equipment 100. Furthermore, during the grinding process, the working parameters of each mechanism can be automatically adjusted, ensuring that the grinding equipment 100 remains in the optimal grinding state. This method achieves a higher degree of automation and effectively improves the grinding efficiency and grinding effect of the grinding equipment 100.

[0121] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. Based on the embodiments of the present invention, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the scope of protection of the present invention.
