Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flower processing, in particular to a photoelectric color selection and impurity removal and grading equipment for jasmine fresh flowers, aiming to efficiently and accurately remove impurities and grade the quality of jasmine fresh flowers in the early stage of processing, meeting the high-quality and standardized demand of the flower industry for jasmine fresh flower raw materials. BACKGROUND

[0002] As an important raw material for many products such as tea, spices, and cosmetics, the quality of jasmine fresh flowers directly affects the quality and market competitiveness of the end products. However, during the primary processing stage after harvesting, there are many challenges. On the one hand, leaves, branches, soil, insects and other impurities are inevitably mixed during the harvesting process. If these impurities are not removed in time, they will not only affect the purity of jasmine fresh flowers, but also may introduce microbial contamination in the subsequent processing process, reducing product quality. On the other hand, due to factors such as growing environment and harvesting time, the quality of jasmine fresh flowers varies, such as flower size, color brightness, and fragrance intensity. Traditional manual sorting methods cannot meet the unified and accurate standards for grading, resulting in uneven product quality and failing to meet the strict requirements of the high-end market for standardized jasmine fresh flower raw materials.

[0030] As shown in the figure, a kind of jasmine flower photoelectric color selection and grading equipment, including main equipment 100, the top of main equipment 100 is equipped with feeding device 200 and display component 300, the inside of main equipment 100 is equipped with photoelectric detection system 400, jet decontamination device 500, grading device 600 and discharge device 700;

[0031] Feeding device 200 includes external conveyor belt 201 and track 202, and external conveyor belt 201 is fixed on annular track 202;Track 202 is fixed on the top of main equipment 100, and the end of track 202 is provided with an inlet, which communicates with the inside of main equipment 100;Discharge device 700 includes internal conveyor belt, which is located in the inside of main equipment 100;Jasmine flowers enter feeding device 200 from the inlet into discharge device 700;Track 202 is driven to rotate by motor, and the front end of track 202 is connected with external flower conveyor. The inside of main equipment 100 is provided with a vibrating mechanism, which is combined with the internal conveyor belt to ensure that jasmine flowers can be evenly dispersed to avoid agglomeration and blockage.

[0032] The photoelectric detection system 400 is located inside the main body device 100, and the photoelectric detection system 400 includes a high-resolution optical camera, a multi-spectral light source, and a smart image processing unit. The high-resolution optical camera captures real-time images of jasmine flowers from multiple angles. The multi-spectral light source emits light covering visible light and near-infrared light, which penetrates the flower to illuminate the internal structure, assisting the camera in obtaining more comprehensive image data. For example, near-infrared imaging can effectively distinguish the water content difference inside the flower, providing more dimensional basis for quality grading. The smart image processing unit has advanced image recognition algorithms built-in, which can quickly analyze and process the collected images based on a deep learning model, accurately identify impurities and flowers of different quality grades in jasmine flowers, and convert the recognition results into electrical signals for real-time transmission to the air jet impurity removal device 500 and the grading device 600.

[0033] The air jet impurity removal device 500 accurately locates the impurity position in a very short time according to the signal transmitted by the photoelectric detection system, and a row of micro air nozzles arranged above the conveying belt rapidly sprays high-pressure gas to blow the impurities away from the conveying belt. The direction, angle, and force of the air jet of the air nozzle can be accurately adjusted. For example, for lighter leaf impurities, soft lateral air jet is used to make them fall into a collection tank on one side; for heavier branches or soil blocks, the air jet force is increased and the air jet angle is adjusted to be obliquely downward to ensure effective removal. The air jet source is provided by an air compressor, which has stable pressure and can be intelligently controlled according to the type of impurities and the processing speed to avoid damage to jasmine flowers caused by excessive air jet;

[0034] The grading device 600 grades jasmine flowers based on their color, size, shape, and aroma. It uses multiple sets of adjustable spacing grading rollers and corresponding grading conveyors below to work together. The surface of the grading roller is wrapped with soft rubber to prevent scratching the flowers, and its spacing can be dynamically adjusted by an electric adjustment mechanism according to the preset flower size standard. When the flowers move along the conveying belt to the grading area, flowers of different sizes will be stuck between the grading rollers with corresponding spacing and roll down to the corresponding lower grading conveyor, realizing preliminary size grading. At the same time, a high-sensitivity aroma sensor array is installed above the grading area, which can detect the aroma concentration and composition of the flowers in real time. Combined with the judgment of color and shape by the photoelectric detection system, the quality grade of the flowers is determined by the intelligent control system, and the flowers are further subdivided into different final grade conveyors to complete fine grading.

[0035] The display assembly 300 is located at the top of the main body device 100, and the display assembly 300 is used to display the parameter configuration of each device. The display assembly 300 is a touch display screen. The top of the main body device 100 is also provided with a fill light 101.
