Description

Technical Field

[0001] The invention relates to the technical field of rice detection, in particular to an online detection and collection device for broken rice rate. Background Art

[0002] During rice processing, some rice is broken due to the crushing and collision of the machine. The broken rice rate is an important indicator of rice quality and processing technology. Traditional detection methods mainly rely on manual sampling, screening, and weighing, which have problems such as low efficiency and poor real-time performance.

[0003] A search revealed a Chinese patent with publication number CN212747703U that discloses an online detection and collection device for broken rice rate. The device comprises a lower hopper and a structural box fixedly disposed in the middle of the lower hopper. The structural box is disposed on the lower hopper, and an image acquisition camera disposed at the bottom of the structural box can periodically capture images of the rice and transmit the image information to an image processing chip. After calculating the area of ​​all rice grains, the image processing chip simultaneously analyzes the area of ​​the broken rice grains, divides the area of ​​the broken rice grains by the total area of ​​the rice grains, and obtains the broken rice rate of the rice. The information is then transmitted to a control baseboard, and a processor chip on the control baseboard transmits the information to the cloud via a GPRS communication module, thereby realizing remote transmission of the detection data. This device can detect the broken rice rate of rice during the rice processing process, is easy to operate, and is suitable for widespread use.

[0004] In the above technology, although the image acquisition camera is designed to capture images of rice and the broken rice rate of rice is analyzed by the image processing chip, the above image acquisition camera captures images of the rice sliding on the lower hopper. Since the rice slides on the lower hopper at a high speed and cannot be stopped, it is difficult for the image acquisition camera to capture a clear image of the rice, which in turn affects the subsequent calculation of the broken rice rate.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention receives rice injected from a feed port through a material receiving mechanism, and the rice falls onto the top of a colored transparent plate. Then, a scraper is used to evenly scrape the rice on the top of the colored transparent plate, so that a single layer or a nearly single layer of rice is formed on the top of the colored transparent plate. Then, a servo motor drives the material receiving mechanism to move below a camera. At this time, a light is turned on, and the colored transparent plate emits colored light under the illumination of the light. At this time, the camera can capture the portion of the colored transparent plate between the rice grains. Then, a screening mechanism is used to screen out broken rice on the colored transparent plate, leaving intact rice on the colored transparent plate. At this time, the camera again captures the portion of the colored transparent plate between the intact rice grains, and the percentage of broken rice is calculated based on the captured image.

[0022] The present invention uses the design of the guide plate, the mounting block and the roller to ensure that the colored transparent plate can always maintain a horizontal state when it moves on the horizontal part of the guide plate. When the material receiving mechanism moves in the horizontal part, it will be connected with the screening mechanism. At this time, the screen will be fixed above the colored transparent plate. When the colored transparent plate moves to the inclined part of the guide plate, the mounting block and the roller will lose their limit, and the gear will mesh with the rack. When the material receiving mechanism continues to move, the gear will roll on the rack, thereby driving the rotating shaft, the first fixed frame, the colored transparent plate and the screen to rotate, thereby causing the colored transparent plate and the screen to flip, so that the rice falls onto the screen. At this time, the screen is driven to vibrate by the vibration motor to screen out broken rice.

In addition, a slot is provided at one end of the slide groove, and a magnet is provided at the slot inside the first fixed frame.

During this process, the spring will extend, and the first fixed frame can drive the second fixed frame and the screen to move. When the rice is screened and moves toward the camera, the second fixed frame will be reconnected to the U-shaped frame. Under the limiting action of the U-shaped frame, the second fixed frame cannot continue to move. At this time, the magnetic beads will move back into the accommodating slot under the extrusion action, so that the first fixed frame can continue to move. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] See also Figures 1-10 The present invention provides a technical solution: an online detection and collection device for broken rice rate, comprising a housing 1, a guide rail 2, a material receiving mechanism 4, a scraper 6 and a camera 7, wherein two guide rails 2 are provided and are fixedly connected to both ends of the housing 1 respectively, one end of the guide rail 2 is slidably connected to a first slider 3, the material receiving mechanism 4 is arranged inside the housing 1, and the material receiving mechanism 4 comprises a first fixed frame 401, a colored transparent plate 402 and a light emitting lamp 403, the first fixed frame 401 is rotatably connected to the first slider 3, one end of the inner wall of the first fixed frame 401 is fixedly connected to the colored transparent plate 402, and the inner wall of the first fixed frame 401 is located below the colored transparent plate 402 A plurality of light-emitting lamps 403 are fixedly connected, a scraper 6 is fixedly connected to one end of the top of the inner wall of the casing 1, and a camera 7 is fixedly connected to one end of the top of the inner wall of the casing 1 and is located adjacent to the scraper 6; a feed port 15 is provided at one end of the top of the casing 1, a first discharge port 16 is provided on the side wall of the casing 1 at one end of the feed port 15, and a second discharge port 17 is provided at the end of the casing 1 away from the first discharge port 16; the casing 1 is rotatably connected to a screw rod 10 located above the guide rail 2, the screw rod 10 is threadedly connected to the first slider 3, and two servo motors 11 are fixedly connected to one end of the outer wall of the casing 1 at the second discharge port 17, and the output end of the servo motor 11 is fixedly connected to the screw rod 10;

[0037] Specifically, the colored transparent plate 402 can be made of an acrylic plate or a colored glass plate, and it is best to use a transparent plate with filtering properties to prevent the light emitted by the subsequent light-emitting lamp 403 from affecting the shooting of the camera 7. When detecting the broken rice rate of rice, the servo motor 11 is first used to drive the screw rod 10 to rotate, thereby driving the first slider 3 to move on the guide rail 2, and then driving the first fixed frame 401, the colored transparent plate 402 and the light-emitting lamp 403 to move, so that the colored transparent plate 402 moves to the bottom of the feed port 15. At this time, rice is injected into the casing 1 through the feed port 15. During this process, the rice will fall on the top of the colored transparent plate 402, and then the servo motor 11 is used to drive the screw rod 10 to rotate, thereby driving the first fixed frame 40 1 and the colored transparent plate 402 move toward the camera 7. During the movement, the colored transparent plate 402 passes under the scraper 6, and the scraper 6 scrapes the rice on the top of the colored transparent plate 402 to form a single layer or a nearly single layer of rice on the top of the colored transparent plate 402. When the colored transparent plate 402 moves below the camera 7, the servo motor 11 is turned off and the light emitting lamp 403 is turned on at the same time. Under the illumination of the light emitting lamp 403, the colored transparent plate 402 can emit colored light. At this time, the camera 7 can capture the portion of the colored transparent plate 402 between the rice grains. When in use, the camera 7 needs to be connected to a controller, and the controller calculates the area of ​​the portion of the colored transparent plate 402 captured by the camera 7 to facilitate the subsequent calculation of the percentage of broken rice.

[0038] Figures 3 to 5 、 Figure 9 As shown, the first fixed frame 401 has a rotating shaft 404 fixedly connected at both ends, the rotating shaft 404 is rotatably connected to the first slider 3, and a vibration motor 405 is fixedly connected to the bottom of the first fixed frame 401; the housing 1 is fixedly connected to the guide plates 8 at the upper and lower ends of the rotating shaft 404, the guide plate 8 is provided with a horizontal portion 801 in the middle, and the guide plate 8 is provided with inclined portions 802 at both ends of the horizontal portion 801; one end of the rotating shaft 404 is fixedly connected to the mounting block 409, and the upper and lower ends of the mounting block 409 are rotatably connected to the rollers 410, and the rollers 410 are in rolling connection with the horizontal portion 801;

[0039] Specifically, the design of the rotating shaft 404 allows the first fixed frame 401 to be smoothly rotatably connected to the first slider 3, and the vibration generated by the vibration motor 405 can make the rice on the colored glass vibrate evenly to avoid piling up. The design of the guide plate 8 can limit the rotating shaft 404. When the rotating shaft 404 is located at the horizontal portion 801 of the guide plate 8, the rollers 410 at the upper and lower ends of the mounting block 409 will respectively contact the horizontal portions 801 on the two guide plates 8, thereby limiting the mounting block 409 and the rotating shaft 404, so that the rotating shaft 404 will not rotate, so that the colored glass can always remain horizontal and avoid rice falling. When the rotating shaft 404 moves to the inclined portion 802 of the guide plate 8, the mounting block 409 loses its limit, and the rotating shaft 404 can rotate, so that the rice on the colored transparent plate 402 can be discharged smoothly.

[0040] like Figure 1 、 Figures 6 to 8 As shown, it also includes a screening mechanism 5, which includes a second fixed frame 501 and a screen 502. The second fixed frame 501 is slidably connected to the casing 1 and is located adjacent to the camera 7. One end of the inner wall of the second fixed frame 501 is fixedly connected to the screen 502, and the second fixed frame 501 is arranged above the first fixed frame 401; one end of the top of the inner wall of the casing 1 is fixedly connected to a U-shaped frame 12, and the opening direction of the U-shaped frame 12 is opposite to the direction of the camera 7. The two ends of the inner wall of the U-shaped frame 12 are respectively fixedly connected to the protrusions 13, and the two ends of the outer wall of the second fixed frame 501 are respectively provided with grooves 503, which are slidably connected to the protrusions 13; the two ends of the outer wall of the first fixed frame 401 are respectively provided with slide grooves 406, The second fixed frame 501 has second sliders 504 fixedly connected to the outer wall at both ends thereof, which are adapted to the slide groove 406. A locking groove 407 is provided at one end of the slide groove 406. A magnet is provided at the locking groove 407 inside the first fixed frame 401. A receiving groove 505 is provided at one end of the second slider 504. A spring 506 is fixedly connected to the interior of the receiving groove 505. A magnetic bead 507 is fixedly connected to one end of the spring 506. The magnetic bead 507 is movably engaged with the locking groove 407. The rotating shaft 404 is fixedly connected to a gear 408 at a position adjacent to the mounting block 409. The inner wall of the housing 1 has racks 14 fixedly connected to the positions adjacent to the guide plate 8 at both ends thereof, which are adapted to the gear 408. The rack 14 is provided below the rotating shaft 404.

[0041] Specifically, after the camera 7 takes the first shot of the colored transparent plate 402 and the rice on top thereof, the servo motor 11 is used to drive the screw rod 10 to rotate again, thereby driving the first slider 3, the rotating shaft 404, the first fixed frame 401 and the colored transparent plate 402 to move toward the second fixed frame 501. During this process, the chutes 406 on both sides of the first fixed frame 401 are connected to the second sliders 504 on both sides of the second fixed frame 501. When the slot 407 at one end of the chutes 406 moves to the position of the receiving groove 505, the magnetic beads 507 in the receiving groove 505 are adsorbed together with the magnet inside the first fixed frame 401, and the magnetic beads 507 in the receiving groove 505 are adsorbed together. When the magnetic bead 507 is stuck in the card slot 407, the spring 506 will stretch during this process. It should be noted that in the initial state, the magnetic bead 507 is completely in the receiving groove 505, thereby preventing the magnetic bead 507 from being stuck in the card slot 407. At this time, the second fixed frame 501 moves under the push of the first fixed frame 401. When the magnetic bead 507 is stuck in the card slot 407, the first fixed frame 401 can drive the second fixed frame 501 and the screen 502 to move. When the rotating shaft 404 moves to the inclined portion 802 position of the guide plate 8, the rotating shaft 404 will lose its limit and can rotate. At the same time, the gear 408 at one end of the rotating shaft 404 The gear 408 will come into contact with the rack 14. Under the continuous drive of the servo motor 11, the gear 408 will roll on the rack 14, thereby driving the rotating shaft 404, the first fixed frame 401, the colored transparent plate 402 and the screen 502 to rotate, so that the colored transparent plate 402 and the screen 502 are flipped, so that the rice falls on the screen 502. At this time, the screen 502 is driven to vibrate by the vibration motor 405 to screen out the broken rice. Then the servo motor 11 drives the first fixed frame 401, the colored transparent plate 402 and the second fixed frame 501 to move toward the camera 7. During this process, the first fixed frame 401 and the second fixed frame 501 can be reset. , let the rice fall back onto the colored transparent plate 402. During the movement, the second fixed frame 501 will be reconnected to the U-shaped frame 12. Under the limiting effect of the U-shaped frame 12, the second fixed frame 501 cannot continue to move. At this time, the magnetic beads 507 will move back into the receiving groove 505 under the extrusion effect, so that the first fixed frame 401 can continue to move to the bottom of the camera. At this time, the camera is used again to shoot. At this time, the colored transparent plate 402 is full of whole rice, and all broken rice has been sieved out. Therefore, the area of ​​the colored transparent plate 402 photographed this time minus the area of ​​the colored transparent plate 402 photographed for the first time can be used to obtain the proportion of broken rice.

[0042] like Figure 1 and Figure 10 As shown, the inner wall of the casing 1 is fixedly connected to a guide plate 9 below the guide plate 8. The guide plate 9 is provided with a first guide portion 901 at one end of the first discharge port 16, and a second guide portion 902 at one end of the guide plate 9 is provided at the second discharge port 17.

[0043] Specifically, when the broken rice is screened, the first fixed frame 401, the colored transparent plate 402, the second fixed frame 501 and the screen 502 are located at one end of the second discharge port 17. At this time, the screened broken rice will fall on the top of the second guide portion 902 of the guide plate 9, and slide along the second guide portion 902 to the second discharge port 17 for discharge. After the camera 7 takes a second shot of the colored transparent plate 402 and the rice on its top, the servo motor 11 is used to drive the colored transparent plate 402 to move toward the first discharge port 16 again. During this process, the rotating shaft 404 will move to the inclined portion 802 of the guide plate 8 at one end of the first discharge port 16. At this time, the rotating shaft 404 loses its limit, and the gear 408 will contact the rack 14 at one end of the first discharge port 16. At this time, under the drive of the servo motor 11, the gear 408 can roll on the rack 14, thereby driving the rotating shaft 404 and the colored transparent plate 402 to rotate, so that the whole rice on the colored transparent plate 402 can fall onto the first guide portion 901 of the guide plate 9, and slide through the first guide portion 901 to the first discharge port 16 for discharge.

[0044] Working principle: When detecting the broken rice rate of rice, the servo motor 11 is first used to drive the screw 10 to rotate, thereby driving the first slider 3 to move on the guide rail 2, and then driving the first fixed frame 401, the colored transparent plate 402 and the light emitting lamp 403 to move, so that the colored transparent plate 402 moves to the bottom of the feed port 15. At this time, rice is injected into the casing 1 through the feed port 15. During this process, the rice will fall to the top of the colored transparent plate 402. The design of the guide plate 8 can limit the rotating shaft 404. When the rotating shaft 404 is located at the horizontal part 801 of the guide plate 8, the rollers 410 at the upper and lower ends of the mounting block 409 will contact the horizontal parts 801 on the two guide plates 8 respectively, thereby limiting the mounting block 409 and the rotating shaft 404, so that the rotating shaft 404 will not rotate, so that the colored glass can always keep water. The servo motor 11 then drives the lead screw 10 to rotate, thereby driving the first fixed frame 401 and the colored transparent plate 402 to move toward the camera 7. During the movement, the lead screw 10 passes under the scraper 6, and the scraper 6 scrapes the rice on the top of the colored transparent plate 402 to form a single layer or a nearly single layer of rice on the top of the colored transparent plate 402. When the colored transparent plate 402 moves below the camera 7, the servo motor 11 is turned off and the light 403 is turned on at the same time. Under the illumination of the light 403, the colored transparent plate 402 can emit colored light. At this time, the camera 7 can capture the portion of the colored transparent plate 402 in the gaps between the rice. When in use, the camera 7 needs to be connected to a controller, which calculates the area of ​​the portion of the colored transparent plate 402 captured by the camera 7 to facilitate subsequent calculation of the percentage of broken rice.

[0045] Then, the servo motor 11 drives the screw rod 10 to rotate again, thereby driving the first slider 3, the rotating shaft 404, the first fixed frame 401 and the colored transparent plate 402 to move toward the second fixed frame 501. During this process, the slide grooves 406 on both sides of the first fixed frame 401 will be connected with the second sliders 504 on both sides of the second fixed frame 501. When the slot 407 at one end of the slide groove 406 moves to the position of the receiving slot 505, the magnetic bead 507 in the receiving slot 505 will be attracted to the magnet inside the first fixed frame 401. At the same time, the magnetic bead 507 will be stuck in the slot 407. During this process, the spring 506 will extend. It should be noted that in the initial state, the magnetic bead 507 is completely in the receiving slot 505, thereby preventing the magnetic bead 507 from being stuck in the slot 407. At this time, the second fixed frame 501 moves under the push of the first fixed frame 401. When the magnetic bead 507 is stuck When the first fixed frame 401 is in the slot 407, the first fixed frame 401 can drive the second fixed frame 501 and the screen 502 to move. When the rotating shaft 404 moves to the inclined portion 802 of the guide plate 8, the rotating shaft 404 will lose its limit and can rotate. At the same time, the gear 408 at one end of the rotating shaft 404 will contact the rack 14. Under the continuous drive of the servo motor 11, the gear 408 will roll on the rack 14, thereby driving the rotating shaft 404, the first fixed frame 401, the colored transparent plate 402 and the screen 502 to rotate, so that the colored transparent plate 402 and the screen 502 are flipped, so that the rice falls on the screen 502. At this time, the vibration motor 405 drives the screen 502 to vibrate and the broken rice can be sieved out. At this time, the sieved broken rice will fall on the top of the second guide portion 902 of the guide plate 9 and slide along the second guide portion 902 to the second discharge port 17 for discharge.

[0046] Then, the servo motor 11 drives the first fixed frame 401, the colored transparent plate 402 and the second fixed frame 501 to move toward the camera 7. During this process, the first fixed frame 401 and the second fixed frame 501 can be reset, allowing the rice to fall back onto the colored transparent plate 402. During the movement, the second fixed frame 501 will be reconnected to the U-shaped frame 12. Under the limiting effect of the U-shaped frame 12, the second fixed frame 501 cannot move further. At this time, the magnetic beads 507 will move back into the receiving groove 505 under the extrusion effect, so that the first fixed frame 401 can continue to move to the bottom of the camera. At this time, the camera is used again to shoot. At this time, the colored transparent plate 402 is full of whole rice, and the broken rice has been sieved out. Therefore, the area of ​​the colored transparent plate 402 photographed this time is subtracted from the area of ​​the colored transparent plate photographed for the first time. The area of ​​the colored transparent plate 402 can be used to obtain the proportion of broken rice. After the camera 7 takes a second picture of the colored transparent plate 402 and the rice on top of it, the servo motor 11 drives the colored transparent plate 402 to move toward the first discharge port 16 again. During this process, the rotating shaft 404 will move to the inclined portion 802 of the guide plate 8 at one end of the first discharge port 16. At this time, the rotating shaft 404 loses its limit, and the gear 408 will contact the rack 14 at one end of the first discharge port 16. At this time, the gear 408 can roll on the rack 14 under the drive of the servo motor 11, thereby driving the rotating shaft 404 and the colored transparent plate 402 to rotate, so that the whole rice on the colored transparent plate 402 can fall onto the first guide portion 901 of the guide plate 9, and slide through the first guide portion 901 to the first discharge port 16 for discharge.
