Description

Technical Field

[0001] This utility model relates to the field of fresh ginseng quality grading, and in particular to a feeding mechanism for a fresh ginseng quality grading device. Background Technology

[0002] Fresh ginseng, a precious traditional Chinese medicine resource, directly impacts market demand and economic benefits due to its quality. After harvesting, fresh ginseng needs to be sorted according to its size and grade. This size and grading is a crucial step in the harvesting and sale of fresh ginseng, and the quality of this sorting directly affects its economic value. After harvesting, larger ginseng with thicker stems are grouped together for use as medicinal slices; smaller ginseng with thinner stems is grouped together and processed into health products.

[0003] Currently, the sorting and grading of fresh ginseng in my country is still mainly done manually, which suffers from low efficiency, high cost, and strong subjectivity, making it difficult to meet the needs of large-scale production and the market. Furthermore, the existing sorting system lacks a cleaning mechanism, relying solely on manual cleaning of fresh ginseng. Manual cleaning not only consumes a significant amount of manpower and time, but also results in inconsistent cleaning quality. Without a manual cleaning step, the mud and impurities adhering to the surface of the fresh ginseng can make sorting difficult. Since fresh ginseng is inherently irregular in shape, mud further complicates identification, making it difficult for both manual methods and image recognition equipment to accurately extract the size of the ginseng. This reduces the accuracy and reliability of the grading results and ultimately lowers the quality of the fresh ginseng products. Utility Model Content

The airflow distributor 703 is electrically connected to the electronic control processing unit 601.

[0032] In practice, the fresh ginseng to be graded is placed at the starting end of the conveying mechanism 1, and the drive motor 101 is started. The motor drives the first transmission wheel 102, which in turn drives the transmission wheel assembly 103 via the first transmission belt 104, thereby driving the roller 105 to rotate and convey the fresh ginseng. At the same time, the water pump 304 starts working, drawing water from the open water tank 301. The water flows through the outlet pipe 303 and the delivery pipe 305 into the distributor 307, and then sprays out from the spray nozzles 309 of several distributor pipes 308 to wash the fresh ginseng. Wastewater and sludge fall into the open water tank 301 through the gaps in the roller 105 and are recycled through the filter port 302.

[0033] After cleaning, the fresh ginseng is conveyed to the end of the conveyor mechanism 1 and orderly collected via the guide ramp 201, then sequentially transferred to the first conveyor belt 509. At this time, electric motors 501 and 502 are activated, driving the dual conveyor belt mechanism 5. When the fresh ginseng moves along the first conveyor belt 509 to below the detection camera 604, the camera captures an image and transmits it to the image processor 602. The image processor 602 analyzes the image according to preset grading standards to determine the quality grade of the fresh ginseng, and the electronic control processing unit 601 controls the jetting mechanism 7 based on the analysis results.

[0034] If the fresh ginseng is detected to be of a smaller size, the electronic control processing unit 601 controls the corresponding small air valve 704 on the airflow distributor 703 to open. The air generated by the air pump 701 is blown onto the conveyor belt 516 via the air delivery pipe 702, the airflow distributor 703, and the air jet nozzle 705, achieving grading and distribution. The limit body 517 on the conveyor belt 516 prevents the conveyor belt from deviating, and the partition on the support platform 4 prevents the small ginseng from falling. The graded fresh ginseng is transported to the designated location by the first conveyor belt 509 and the second conveyor belt 516 for further processing.
