Description

Technical Field

[0001] This utility model relates to the field of color sorters, specifically an enhanced imaging auxiliary device for rice color sorters. Background Technology

[0002] Rice color sorters are machines that automatically separate colored grains from rice based on differences in the optical properties of the rice using photoelectric technology. This improves rice quality and removes impurities. Compared with manual sorting, rice color sorters have advantages such as saving labor, time, and effort, high efficiency, and low processing costs.

[0003] Existing rice color sorters lack a proper guiding mechanism because rice enters directly from the feed inlet as it falls from the slide plate. Furthermore, the planar structure of the feed chute makes it impossible to adjust and control the orderly and sequential descent of rice grains, preventing multiple grains from overlapping during imaging detection. This affects image clarity and increases the likelihood of misjudgments, thus limiting and reducing the sorting efficiency of the color sorter. Moreover, rice grains inevitably slip across the cross-section of the planar feed plate, while the spray valves below are spaced out and operate non-linearly. Therefore, rice grains slipping between two spray valves cannot be effectively targeted, further reducing the sorting efficiency. Therefore, there is a need to develop an enhanced imaging auxiliary device for rice color sorters to address the shortcomings of existing technologies. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing an enhanced imaging auxiliary device for rice color sorters.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An enhanced imaging auxiliary device for a rice color sorter includes a housing, a top plate installed on the top of the housing, a feeding assembly installed on the top of the top plate, a feeding plate arranged inside the housing, the upper end of the feeding plate having an inclined structure, the lower end of the feeding plate having a vertical structure, the upper and lower ends of the feeding plate being smoothly connected, and the upper end of the feeding plate extending directly below the feeding assembly.

[0006] The beneficial effects of this utility model are: under the action of the drive mechanism, the feeding plate can divert the feeding, so that different areas on the detection imaging mechanism can be responsible for similar imaging detection work, avoiding the situation that the workload in the middle is high while the imaging workload at both ends is low. Moreover, it can ensure that the slipping rice grains can always pass through the spray valve accurately, thereby ensuring that the airflow sprayed from the spray valve can accurately act on the rice grains and improve the sorting effect.

[0007] Preferably, the feeding plate includes a guide plate movably installed inside the housing. The side of the guide plate that contacts the rice grains has several diversion channels evenly distributed front and back. Each diversion channel corresponds to a spray valve, and the spray valve is located on the right side below a corresponding diversion channel.

[0008] Preferably, the housing is further provided with a detection imaging mechanism parallel to the lower side of the feeding plate, and a gap is left between the detection imaging mechanism and the feeding plate. The housing is also provided with a plurality of spray valves located below the detection imaging mechanism and evenly distributed. The gaps not only ensure that the rice grains can pass through one by one in an orderly manner, but also prevent the rice grains from getting stuck. At the same time, they can effectively prevent multiple rice grains from overlapping and affecting the image clarity.

[0009] Preferably, a separator is also installed inside the housing. The upper end of the separator is located below the horizontal plane in front of the spray valve. A discharge plate is provided on both the left and right sides of the housing. The separator facilitates the spray valve to spray unqualified rice grains to one side, while the qualified rice grains fall directly to the other side of the separator, thus separating them and facilitating their discharge through the two discharge plates.

[0010] Preferably, the outer surface of the guide plate and the inner wall of the diversion slide are both smooth, the inner diameter of the diversion slide is larger than the diameter of a grain of rice, and the gap between the lower end of the guide plate and the detection imaging mechanism is larger than the diameter of a single grain of rice and smaller than the sum of the diameters of two grains of rice. By setting the detection size, it is ensured that a single grain of rice can slide smoothly, while two overlapping grains of rice cannot pass through. This effectively avoids the situation where overlapping grains of rice pass through the detection imaging mechanism at the same time, thus affecting the clear and distinct imaging effect.

[0011] Preferably, a drive mechanism is provided inside the housing, and a drive motor is provided inside the drive mechanism. The output end of the drive motor is connected to a vibration component and a feeding component. The vibrating component allows the rice grains to slide smoothly one by one along the slide and between the detection and imaging mechanism, facilitating a clear imaging effect and preventing blockages in the feeding component.

[0012] Preferably, the vibration component consists of two eccentric wheels, rocker arms, a vibration frame, and a limiting block. The lower ends of the two rocker arms are rotatably connected to the opposite sides of the two eccentric wheels, and the other end of the rocker arms is hinged to the bottom of the vibration frame. The limiting block is fixedly connected to both ends of the vibration frame and the bottom of the guide plate, and is slidably engaged with the inner wall of the housing. Under the action of the drive motor, the two continuously rotating eccentric wheels can drive the upper ends of the two rocker arms to move up and down reciprocally through the transmission rod. Thus, under the restriction of the spray valve, the vibrating frame and the limit block drive the feeding plate to move up and down reciprocally, thereby achieving the situation where rice grains are stuck between the continuously vibrating guide plate and the detection imaging mechanism.

[0013] Preferably, a drive box located between two eccentric wheels is fixedly installed inside the housing. The drive motor is located inside the drive box, and the output end of the drive motor is fixedly connected to the front and rear eccentric wheels through a transmission rod. Through the continuous rotation of the two eccentric wheels, the slide rail can be driven to vibrate through the transmission rod, thereby ensuring that the rice grains in the slide rail slide smoothly and avoiding blockage.

[0014] Preferably, the feeding component consists of two first pulleys (front and rear), a transmission belt, and a second pulley. The two first pulleys are connected to the output end of the drive motor via a transmission shaft, and the two second pulleys are fixedly connected to the front and rear ends of the feeding component. The transmission belt is sleeved between the first pulleys and the second pulleys.

[0015] Preferably, the feeding assembly includes a feeding trough fixedly installed on the top of the top plate, a feeding hopper fixedly connected to the top of the feeding trough, a transfer roller movably sleeved inside the feeding trough, the two ends of the transfer roller being fixedly connected to the facing surfaces of two second pulleys via short shafts, and a plurality of feeding troughs evenly distributed on the outer surface of the transfer roller, the plurality of feeding troughs being connected one by one to the bottom of the feeding hopper, and the plurality of plastic troughs being connected one by one to the interior of the housing and the upper area of ​​the guide plate; Under the transmission action of the feeding component, the feeding groove on the outer surface of the transfer roller can continuously and evenly feed the rice into the upper end of the guide plate with the cooperation of the feeding hopper. This not only effectively avoids the probability of blockage at the lower end of the feeding hopper, but also achieves limited and uniform feeding, ensuring that the rice grains falling into the diversion slide on the guide plate do not pile up, so that they pass through the detection imaging mechanism and the spray valve one by one, ensuring that the detection imaging mechanism can produce clear and accurate images.

It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details.

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0021] Example 1 like Figures 1 to 5 As shown, an enhanced imaging auxiliary device for a rice color sorter includes a housing 1, a top plate 2 installed on the top of the housing 1, a feeding assembly 3 installed on the top of the top plate 2, a feeding plate 4 disposed inside the housing 1, the upper end of the feeding plate 4 is inclined, the lower end of the feeding plate 4 is vertical, the upper and lower ends of the feeding plate 4 are smoothly connected, and the upper end of the feeding plate 4 extends to directly below the feeding assembly 3. The feeding plate 4 includes a guide plate 41 movably installed inside the housing 1. The side of the guide plate 41 that contacts the rice grains has several diversion slides 42 evenly distributed front and back. Each diversion slide 42 corresponds to a spray valve 5. The spray valve 5 is located on the right side below a corresponding diversion slide 42. The operation of the vibration component can drive the guide plate 41 of the feeding plate 4 to move up and down continuously and smoothly to achieve the purpose of vibration, avoid rice grains getting stuck between the slide and the detection mechanism, and prevent blockage in the feeding mechanism.

[0022] The housing 1 is equipped with a detection imaging mechanism 6 parallel to the lower side of the feeding plate 4. A gap is left between the detection imaging mechanism 6 and the feeding plate 4. The housing 1 is also equipped with several spray valves 5 located below the detection imaging mechanism 6 and evenly distributed. When the equipment is started, the spray valves 5 and the detection imaging mechanism 6 are kept running or in standby mode. When the detection imaging mechanism 6 detects unqualified rice grains, it sends a signal to the spray valves 5, causing them to spray air and spray the corresponding unqualified rice grains onto one side of the separator plate 9. When qualified products pass by, the detection imaging mechanism 6 does not send a signal to the spray valves 5, and the spray valves 5 do not operate, so that the qualified rice grains fall directly to the other side of the separator plate.

[0023] The housing 1 is also fitted with a separator 9. The upper end of the separator 9 is located below the horizontal plane in front of the spray valve 5. A discharge plate 8 is provided on both the left and right sides of the housing 1. With the cooperation of the spray valve 5, qualified rice grains and unqualified rice grains fall to the two sides of the separator 9 and are finally taken out through the two discharge plates 8.

[0024] The outer surface of the guide plate 41 and the inner wall of the diversion slide 42 are both smooth. The inner diameter of the diversion slide 42 is larger than the diameter of a rice grain. The gap between the lower end of the guide plate 41 and the detection imaging mechanism 6 is larger than the diameter of a single rice grain but smaller than the sum of the diameters of two rice grains. The guide plate 41 can achieve vibration and linkage, thereby preventing blockage. The rice grains falling into the diversion slide 42 can slide smoothly along its interior and pass through the detection imaging mechanism 6 one by one, and finally pass accurately through the spray valve 5.

[0025] The housing 1 contains a drive mechanism 7, which contains a drive motor. The output of the drive motor is connected to a vibration component and a feeding component.

[0026] The vibration component consists of two eccentric wheels 72, rocker arms 73, a vibration frame 74, and a limiting block 75. The lower ends of the two rocker arms 73 are rotatably connected to the opposite sides of the two eccentric wheels 72, and the other end of the rocker arms 73 is hinged to the bottom of the vibration frame 74. The limiting block 75 is fixedly connected to both ends of the vibration frame 74 and the bottom of the guide plate 41, and is slidably engaged with the inner wall of the housing 1. When the drive motor in the drive box 71 is started, it can drive the two eccentric wheels 72 to rotate through the transmission shaft. Then, under the restriction of the limiting block 75, the eccentric wheels 72 drive the vibration frame 74 to move up and down through the rocker arms 73, thereby driving the loading plate 4 to move up and down, and making it move up and down relative to the detection imaging mechanism 6.

[0027] The housing 1 contains a drive box 71 located between two eccentric wheels 72. The drive motor is located inside the drive box 71, and the output end of the drive motor is fixedly connected to the front and rear eccentric wheels 72 through a transmission rod.

[0028] The feeding component consists of two first pulleys 76, a transmission belt 77, and a second pulley 78. The two first pulleys 76 are connected to the output end of the drive motor via a transmission shaft, and the two second pulleys 78 are fixedly connected to the front and rear ends of the feeding assembly 3. The transmission belt 77 is sleeved between the first pulleys 76 and the second pulleys 78. When the drive motor is running, it drives the two first pulleys 76 to rotate through the transmission system. With the cooperation of the two transmission belts 77 and the second pulleys 78, the transfer roller 33 can be driven to rotate continuously and smoothly.

[0029] The feeding assembly 3 includes a feeding trough 31 fixedly installed on the top of the top plate 2. A feeding hopper 32 is fixedly connected to the top of the feeding trough 31. A transfer roller 33 is movably sleeved inside the feeding trough 31. The two ends of the transfer roller 33 are fixedly connected to the facing surfaces of two second pulleys 78 through short shafts. A plurality of feeding troughs are evenly distributed on the outer surface of the transfer roller 33. The plurality of feeding troughs are connected to the bottom of the feeding hopper 32 one by one. The plurality of plastic troughs are connected to the interior of the housing 1 and the upper area of ​​the guide plate 41 one by one.
