[0039] A paddy and brown rice separator is a kind of agricultural machinery dedicated to paddy processing. It separates the paddy and brown rice after paddy hulling from the rice husks through efficient separation technology, ensuring that the paddy and brown rice enter the subsequent rice processing process, while the rice husks are removed. This equipment usually integrates mechanical technologies such as vibration screening and air separation, and may combine machine vision and intelligent control technologies to improve separation efficiency and accuracy, reduce manual intervention, lower production costs, and at the same time improve the quality of the finished rice. The paddy and brown rice separator plays an important role in improving the automation level of paddy processing and ensuring the quality of grain processing.

[0040] In the related art, to judge the paddy and brown rice ratio, a vision camera may be used to identify and separate the rice husks in the paddy and brown rice. However, since the paddy and brown rice mixture needs to be oscillated to achieve uniform paving before identification, a large amount of dust will be generated during the process of oscillating the paddy and brown rice mixture. The flying particulate matter will adhere to the lens position of the vision camera, causing great interference to the work of the vision camera and reducing the recognition accuracy of the vision camera.

[0041] To solve the above problems, the present utility model provides an impurity identification device and a paddy and brown rice separator, aiming to provide an impurity identification device with higher identification accuracy for husks in the paddy and brown rice mixture. Figures 1 to 4 FIG. 2 is a schematic structural diagram of an embodiment provided by the impurity identification device of the present utility model.

[0042] Please refer to Figures 1 to 4 , the present utility model provides an impurity identification device 1000, including a frame 1, a visual detection component 2 and a cleaning component 3. The frame 1 is used to be arranged at the discharge port of the paddy and brown rice separator. The visual detection component 2 includes a housing 21, a color camera 23 is arranged inside the housing 21. One side of the housing 21 is provided with a detection port, and the detection port is covered with a transparent cover plate 22. The cleaning component 3 includes a driving mechanism 31 and a cleaning member arranged at the driving end 311a of the driving mechanism 31. The cleaning member can reciprocally contact the transparent cover plate 22 to achieve cleaning.

[0043] In the technical solution of the present utility model, an impurity identification device 1000 and a paddy and brown rice separator are provided. Among them, the impurity identification device 1000 includes a frame 1, a visual detection component 2 and a cleaning component 3. The visual detection component 2 includes a housing 21 and a color camera 23 arranged inside the housing 21. The cleaning component 3 includes a driving mechanism 31 and a cleaning member arranged at the driving end 311a of the driving mechanism 31. When performing paddy and brown rice analysis, the driving mechanism 31 will regularly drive the cleaning member to clean the transparent cover plate 22 of the housing 21 to remove the particulate matter, dust, etc. attached to the surface of the transparent cover plate 22, thereby reducing the interference of dust, etc. in the environment on the camera detection, and further improving the identification accuracy of the visual camera during the impurity identification process.

[0044] To accurately identify the husk impurities in paddy and brown rice, a visual recognition scheme is generally adopted to sort the husks. It should be noted that a color camera 23 can be used, or a near-infrared camera can be used to identify the husks. The camera in the near-infrared spectral region can detect the chemical composition differences in plant materials, which helps to distinguish the husks from other impurities. The present utility model does not limit this. In an embodiment of the present utility model, the visual detection component 2 uses a color camera 23. The principle of the color camera 23 to identify the husks in paddy and brown rice is mainly based on the differences in color, texture, and shape between the husks and brown rice. The color camera 23 captures the RGB (red, green, blue) three-primary-color images of the paddy and brown rice mixture, and uses image processing algorithms to analyze these color features to distinguish the husks from the brown rice. For example, the husks may have a higher reflectance in the red or blue channels, while the color of the brown rice may be closer to yellow or brown. By setting appropriate color thresholds, the husks can be effectively separated from the brown rice. In addition, the texture features of the husks, such as edges and contours, and the shape features, such as the aspect ratio of the husks, can be used to further optimize the recognition process and improve the recognition accuracy. The image acquisition part mainly uses the color camera 23 to acquire the images on the vibration platform of the brown rice mixture; the image processing part mainly completes the algorithm processing of the acquired data, and mainly uses the edge region detection algorithm and the image noise elimination algorithm to detect and count the brown rice and the unhusked paddy, so as to detect the brown rice rate of the brown rice mixture in real time. The color camera 23 can capture the color differences between the husks and the brown rice, which makes them easy to be distinguished in the image and improves the recognition accuracy; secondly, the color images provide richer visual information, which helps to apply more complex image processing algorithms to identify the texture and shape features of the husks; in addition, the cost of the color camera 23 is relatively low, it is easy to be integrated into the existing automated systems, and the maintenance is simple, making the whole recognition process more economical and efficient.

[0045] To improve the accuracy of husk recognition and reduce the interference of ambient light on the operation of the color camera 23, the visual detection component 2 further includes a supplementary lighting device. Specifically, please further refer to Figure 3 , the supplementary lighting device is designed to face the transparent cover plate 22. The supplementary lighting device is a strip-shaped LED light source. The LED light source provides stable and uniform lighting, which helps to reduce the influence of ambient light changes on the image quality and ensure clear and consistent images under different lighting conditions; secondly, the LED light source with a specific wavelength can enhance the contrast of the color features between the husks and the brown rice, making their differences in the image more obvious, thus improving the recognition accuracy; furthermore, the directional lighting of the LED light source helps to highlight the surface texture and contour of the object, further optimizing the recognition effect of the image processing algorithm; the low energy consumption and long service life characteristics of the LED light source also make the operation cost of the whole system lower and the maintenance more simple.

[0046] It should be noted that the transparent cover 22 can be made of a transparent acrylic plate or glass. The present invention does not impose any restrictions on this. In one embodiment of the present invention, the transparent cover 22 is made of glass. The glass cover can provide good transparency to ensure that the color camera 23 has a clear field of view. Glass has high hardness and impact resistance to ensure safety. At the same time, the transparent cover 22 made of glass is usually designed to have good sealing properties, which can prevent external dust from entering the cavity in the shell 21 and interfering with the color camera 23.

[0047] In one embodiment of the present invention, the frame 1 includes two vertical plates 11 spaced apart from each other. Figure 1 A crossbeam 12 is provided between the two vertical plates 11, and the visual detection component 2 is provided on the crossbeam 12. To improve the flexibility of the equipment, the crossbeam 12 includes two mounting members 121 and a mounting rod 122. The two mounting members 121 are respectively installed on the bolts 111 of the vertical plates 11 through waist-shaped grooves 121a. The position of the mounting member 121 can be changed by loosening the bolt 111 and sliding it in the waist-shaped groove 121a, thereby changing the position of the mounting member 121, thereby changing the position of the mounting member 121, thereby realizing the lateral adjustment of the visual detection component 2.

[0048] In the technical solution of the utility model, the cleaning part is a brush, the motor 311 is installed on the mounting plate 13 and is provided with an output end, the output end of the motor 311 is connected to the screw rod 312, the sliding limit of the slider 313 is located on the guide rail 314 and is screwed to the screw rod 312, when the motor 311 drives the screw rod 312 to rotate, the thread of the screw rod 312 will drive the slider 313 to move on the guide rail 314, thereby driving the brush to reciprocate and scrape the transparent cover plate 22 to clean the cover plate.
