Abstract
Description
Technical Field
[0001] This utility model relates to the field of channel structure technology, specifically to a channel structure for a rice color sorter. Background Technology
[0002] The channel structure of the rice color sorter is mainly used to realize the rice sorting process. The channel structure is the conveying path of the rice. Its upper end is connected to the feeding section and its lower end is connected to the receiving box, so that the rice can fall smoothly along the channel under the action of the conveyor belt, ensuring that the rice can enter the color sorting area according to the predetermined trajectory. Optical detection components such as light source and CCD camera are set in the channel. When the rice passes through the channel, the light source illuminates the rice, and the rice reflects the light. The reflected light and the light reflected by the contrast plate are received by the CCD camera. The CCD camera converts the light signal into an electrical signal and transmits it to the controller on the outside of the color sorting box.
[0003] The existing technology has the following problems:
[0004] The existing device does not allow for camera replacement during use. When the camera malfunctions, if it cannot be replaced individually, the entire channel structure or even larger components may need to be replaced or repaired, which would significantly increase maintenance costs. In addition, the existing device cannot clean the surface of the LED light source. Dust is generated during the rice color sorting process, and this dust may adhere to the surface of the LED light source. Dust accumulation on the light source surface will cause uneven light emission and weakened intensity, making it difficult for the photoelectric system to accurately obtain the color information of the rice, which can easily lead to false detections, missed detections, and other problems, thus reducing the color sorting accuracy.

[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:
[0023] like Figure 1 As shown, this utility model provides a channel structure for a rice color sorter, including a main body 1. A transmission mechanism 2 is fixedly connected to the upper side of the main body 1. A guide plate 3 is fixedly connected to the rear side of the inner surface of the main body 1. A good product trough 6 is provided at the lower rear end of the main body 1, and a defective product trough 7 is provided at the lower front end of the main body 1. An air pump 5 is fixedly connected to the rear side of the main body 1. An air outlet pipe 4 is fixedly connected to the output end of the air pump 5. The outer wall of the air outlet pipe 4 is fixedly connected to the guide plate 3. A valve is provided inside the air outlet pipe 4. A locking block 8 is fixedly connected to the front side of the main body 1. Rice The rice enters the channel structure from the transmission mechanism 2 on the upper side of the main body 1 and falls smoothly along the guide plate 3 under the action of gravity. The air pump 5 blows air into the channel through the air outlet 4. When the rice passes through the color sorting area, the LED light source 22 illuminates the rice. The reflected light from the rice and the light reflected from the contrast plate are received by the camera 10. The camera 10 converts the light signal into an electrical signal and transmits it to the controller. The controller determines whether the rice is defective based on the signal. If so, it controls the air pump 5 to blow air through the air outlet 4 to blow the defective rice into the defective trough 7, while the good rice falls into the good trough 6.
[0024] like Figure 2-3As shown, this utility model provides a technical solution: Preferably, the front side of the main body 1 has an opening 21, the inner surface of which is movably connected to a camera 10. Slots 11 are provided on both the left and right sides of the camera 10. A knob 12 is rotatably connected to the lower side of the locking block 8, and a threaded rod 13 is fixedly connected to the upper side of the knob 12. A lifting plate 15 is threadedly connected to the outer wall of the threaded rod 13. Two limiting rods 14 are fixedly connected to the lower side of the inner surface of the locking block 8. The outer walls of the limiting rods 14 are slidably connected to the lifting plate 15. Movable blocks 17 are fixedly connected to both the left and right sides of the lifting plate 15. A slanted groove 18 is provided through the front side of the movable block 17. A guide post 19 is slidably connected to the inner surface of the slanted groove 18. An insert plate 9 is fixedly connected to the outer wall of the guide post 19. The inner surface of the locking block 8 is fixedly connected to the guide post 19. The fixed connection is limited by the limit post 16. The outer wall of the limit post 16 is slidably connected to the insertion plate 9. The outer wall of the insertion plate 9 is movably connected to the slot 11. When the camera 10 needs to be replaced, the knob 12 is turned. The knob 12 drives the threaded rod 13 to rotate. Due to the restriction of the limit rod 14, the lifting plate 15 can only move up and down along the limit rod 14. The movable blocks 17 on the left and right sides of the lifting plate 15 also move accordingly. The inclined groove 18 on the movable block 17 cooperates with the guide post 19, so that the insertion plate 9 moves left and right under the restriction of the limit post 16, thereby pulling the insertion plate 9 out of the slot 11 on both sides of the camera 10. The camera 10 can then be taken out for replacement. When installing the camera 10, the above steps are reversed. The camera 10 is inserted into the opening 21, and then the knob 12 is turned to insert the insertion plate 9 into the slot 11 to fix the camera 10.
[0025] like Figure 4-5 As shown, this utility model provides a technical solution: Preferably, an LED light source 22 is fixedly connected to the front side of the inner surface of the main body 1, a guide rod 23 is fixedly connected to the left side of the inner surface of the main body 1, a motor 27 is fixedly connected to the front side of the inner surface of the main body 1, a turntable 28 is fixedly connected to the output shaft of the motor 27, a rotating plate 26 is rotatably connected to the eccentric part of the turntable 28, a moving plate 24 is rotatably connected to the other end of the rotating plate 26, a cleaning plate 25 is fixedly connected to the front side of the moving plate 24, and the cleaning surface of the cleaning plate 25 is movably connected to the LED light source 22. Next, the outer wall of the guide rod 23 is slidably connected to the moving plate 24. After the motor 27 starts, its output shaft drives the turntable 28 to rotate. The rotating plate 26 at the eccentric part of the turntable 28 swings back and forth as the turntable 28 rotates. The moving plate 24 connected to the other end of the rotating plate 26 can only move back and forth in a straight line along the guide rod 23 under the restriction of the guide rod 23. The cleaning plate 25 on the front side of the moving plate 24 also moves back and forth in a straight line, thereby cleaning the surface of the LED light source 22, removing dust, ensuring uniform light emission and stable intensity, and improving color sorting accuracy.
[0026] The working principle of the channel structure of this rice color sorter will be explained in detail below.
[0027] like Figure 1-5As shown, when it is necessary to replace camera 10, turn knob 12. Knob 12 drives threaded rod 13 to rotate. Due to the restriction of limit rod 14, lifting plate 15 can only move up and down along limit rod 14. Movable blocks 17 on both sides of lifting plate 15 also move accordingly. The inclined groove 18 on movable block 17 cooperates with guide post 19, so that insertion plate 9 moves left and right under the restriction of limit post 16, thereby pulling insertion plate 9 out of slot 11 on both sides of camera 10. Camera 10 can then be removed for replacement. When installing camera 10, reverse the above steps and insert camera 10 into the opening. 21. Then turn the knob 12 to insert the plate 9 into the slot 11 to fix the camera 10. After the motor 27 starts, its output shaft drives the turntable 28 to rotate. The rotating plate 26 at the eccentric part of the turntable 28 swings back and forth as the turntable 28 rotates. The moving plate 24 connected to the other end of the rotating plate 26 can only move back and forth in a straight line along the guide rod 23 under the restriction of the guide rod 23. The cleaning plate 25 on the front side of the moving plate 24 also moves back and forth in a straight line, thereby cleaning the surface of the LED light source 22, removing dust, ensuring uniform light emission and stable intensity, and improving color sorting accuracy.
[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
