Detailed Implementation Many specific details are set forth in the following description to provide a full understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this application; therefore, this application is not limited to the specific embodiments disclosed below.

[0023] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] In the processing of traditional Chinese medicine, herbs need to be stir-fried, including methods such as stir-frying with wheat bran, stir-frying with sand, stir-frying with clam powder, stir-frying with talcum powder, honey-processing, vinegar-processing, wine-processing, and ginger juice-processing. Stir-frying can enhance the therapeutic effects of the herbs, improve their efficacy, and also eliminate toxicity and reduce side effects in some herbs. Appropriate stir-frying equipment is required for this process.

[0026] In existing techniques, the raw medicinal herbs to be stir-fried are directly placed inside the wok, and a motor-driven transmission mechanism (such as gears or belts) rotates the drum. The drum's tilt angle (typically 3°-5°) and internal lifting plates achieve a cyclical "lifting-falling-tumbling" stir-frying process. However, when observing the herbs in different states, manual sampling tools are generally used. This process is time-consuming and labor-intensive, and manual operation is inherently unpredictable; excessive force can easily damage the herbs.

[0027] Accordingly, this application provides a negative pressure sampling device for Chinese medicinal materials and processed Chinese medicinal slices, comprising: a sorting mechanism, a feeding mechanism, a stir-frying mechanism, and a sampling mechanism. The sorting mechanism is connected to the front end of the feeding mechanism and is used to classify the Chinese medicinal materials into grades according to a preset quality index model, assigning different grades of Chinese medicinal materials to corresponding grade areas. The feeding mechanism is connected to the end of the stir-frying mechanism, which automatically transports the Chinese medicinal materials from the grade areas to the stir-frying mechanism according to preset requirements. The stir-frying mechanism is connected to the sampling mechanism, and each processing section of the stir-frying mechanism can stir-fry the Chinese medicinal materials to different degrees. The sampling mechanism is equipped with multiple sampling components, each of which is connected to a specific processing section to perform negative pressure vacuum sampling of the Chinese medicinal materials in each processing section.

[0028] This application's negative pressure sampling device for Chinese medicinal materials and processed Chinese medicinal herbs can be understood as follows: A sorting mechanism classifies Chinese medicinal materials into different grades based on a preset quality index model, thereby improving the accuracy of grade classification. A feeding mechanism automatically transports the Chinese medicinal materials from the corresponding grade area to the processing mechanism according to preset requirements. Each processing section of the processing mechanism processes the Chinese medicinal materials to different degrees. Each sampling component of the sampling mechanism performs negative pressure vacuum sampling of the Chinese medicinal materials in each processing section. The automated sampling mechanism improves sampling efficiency during Chinese medicinal material sampling.

[0030] like Figures 1 to 5 As shown, this application provides a negative pressure sampling device for Chinese medicinal materials and processed Chinese medicinal slices, including: a sorting mechanism 1, a feeding mechanism 2, a stir-frying mechanism 3, and a sampling mechanism 4.

The end of the feeding mechanism 2 is connected to the stir-frying mechanism 3, which can automatically transport the Chinese medicinal materials in the grade areas to the stir-frying mechanism 3 according to preset requirements. The stir-frying mechanism 3 is connected to the sampling mechanism 4, and each processing section of the stir-frying mechanism 3 can stir-fry the Chinese medicinal materials to different degrees. The sampling mechanism 4 is equipped with multiple sampling components 45, and each sampling component 45 is connected to each processing section to perform negative pressure vacuum sampling of the Chinese medicinal materials in each processing section.

[0031] Specifically, in this embodiment, the sorting mechanism 1 is connected to the front end of the feeding mechanism 2. The sorting mechanism 1 is used to classify traditional Chinese medicine (TCM) according to a preset quality index model and to classify TCM of different grades into corresponding grade areas. The sorting mechanism 1 includes: a feeding device 11, a sorting body 12, a hyperspectral camera 13, an intelligent algorithm control system 14, a display 15, and multiple sets of dividing components 16. The feeding device 11 is connected to the front end of the sorting body 12 and is used to feed TCM to the sorting body 12. In one example, the feeding device 11 includes: a first support, a feeding motor, support bearings, a conveyor shaft, and a first conveyor belt. The feeding motor is mounted on the first support, and the support bearings are respectively disposed on opposite ends of the first support in a first direction, and opposite to each other on both sides in a second direction at each end. The conveyor shaft is movably disposed on the opposite support bearings and connected to the output end of the feeding motor. The first conveyor belt is wound around the two conveyor shafts along the first direction to move under the rotation of the conveyor shafts. The first direction is the direction in which the first conveyor belt transports the TCM. The head end of the sorting body 12 is connected to the feeding device 11, and specifically, the first conveyor belt of the feeding device 11 is connected to the main conveyor belt in the sorting body 12. The main conveyor belt in the sorting body 12 can carry and transport the Chinese medicine conveyed by the first conveyor belt of the feeding device 11.

[0032] A hyperspectral camera 13 is installed inside the sorting body 12 and can acquire image information of the Chinese medicine on the main conveyor belt in real time. An intelligent algorithm control system 14 is connected to the hyperspectral camera 13. The system uses a Chinese medicine classification model to identify and extract image information, outputting multiple key quality indicators of the detected Chinese medicine and classifying it according to these indicators. Multiple classification components 16 are connected to the end of the sorting body 12. These components are used to classify the graded Chinese medicine into corresponding grade areas. In one example, the classification component 16 includes a classification conveyor track, a grade area box, claws, sensors, and a drive motor. The classification conveyor tracks are arranged in parallel and positioned between the end of the sorting body 12 and the grade area box. The drive motors are respectively located on the sides of the corresponding classification conveyor tracks. One end of each claw is positioned at the beginning of the classification conveyor track, and the other end of the claw is connected to the drive motor to swing under its drive. The sensor is connected to the drive motor and can sense the graded Chinese medicine to drive the drive motor accordingly, thereby dividing the Chinese medicine of the corresponding grade into the corresponding grade conveyor track and transporting it to the corresponding grade area box. The display 15 is connected to the intelligent algorithm control system 14 and is used to set the acquisition parameters of the hyperspectral camera 13 and adjust the rotation speed and direction of the main conveyor belt.

[0033] The sorting mechanism 1 is connected to the front end of the feeding mechanism 2 to obtain Chinese herbal medicines of different grades sorted by the sorting mechanism 1. In this embodiment, the feeding mechanism 2 includes a feeding box 21, a suction pipe 22, a suction motor, a support frame 23, and a feeding conveyor belt 24. The suction pipe 22 is connected to the suction motor, which provides suction force to the suction pipe 22. The suction pipe 22 and the suction motor are mounted on the feeding box 21. One end of the suction pipe 22 is connected to a graded area of ​​the sorting mechanism 1 to suction the Chinese herbal medicines from the corresponding graded area. The feeding conveyor belt 24 is movably mounted on the support frame 23, and the other end of the suction pipe 22 is connected to the feeding conveyor belt 24 to transport the suctioned Chinese herbal medicines onto the feeding conveyor belt 24.

[0034] In one example, a robot can also be used to move Chinese medicine from the Chinese medicine grabbing level area to the feeding conveyor belt 24.

[0035] The end of the feeding mechanism 2 is connected to the stir-frying mechanism 3 (specifically, the feeding conveyor belt 24 is connected to the stir-frying mechanism 3). The feeding mechanism 2 can automatically transport the Chinese medicine in the corresponding grade area to the stir-frying mechanism 3 according to preset requirements. Each processing section of the stir-frying mechanism 3 can stir-fry the Chinese medicine according to different degrees of stir-frying. In this embodiment, the stir-frying mechanism 3 includes: a coil support 31, a coil 32, a roller 33, and a drive motor. The coil 32 is installed on the coil support 31, and the roller 33 is wrapped in the coil 32. The roller 33 can carry the Chinese medicine. The drive motor is set on the side of the coil support 31 and connected to the roller 33 to drive the roller 33 to rotate. When the coil 32 is energized, it can generate a magnetic field. When the magnetic lines of force inside the magnetic field pass through the roller 33, eddy currents can be generated, so that the roller 33 heats up at high speed, thereby heating the Chinese medicine inside the roller 33. In one example, the roller 33 can be set as a multi-segment, that is, the roller 33 is set into multiple processing sections according to preset dimensions, and each processing section is arranged sequentially according to the degree of stir-frying (program) of the Chinese medicine. The circumferential coil 32 of each pharmaceutical preparation section can be set according to the required magnetic flux to ensure that the heat of each pharmaceutical preparation section is generated according to the degree of stir-frying of Chinese medicine.

[0036] In one example, the frying mechanism 3 also includes a heat insulation layer 34 disposed on the outside of the drum 33.

[0037] Electromagnetic heating boasts high thermal efficiency, ensuring a safe and clean processing environment with no smoke, no fire, and is unaffected by wind. When magnetic field lines pass through a non-magnetic object, no eddy currents or heat are generated, preventing other parts from heating up. Since the human body is a non-magnetic object, there is no risk of burns from the electromagnetic herbal stir-fry machine, making it extremely safe for users.

[0040] In this embodiment, the sieving assembly 44 includes a support frame 441, a tipping cylinder 442, a vibrating screen plate 443, a collection tank 444, and a tipping bucket.
