A heating cavity 106 that is recessed downward and used to accommodate the metering heating cup 1001 is provided on the surface of the heating base 100. Specifically, the metering heating cup 1001 is heated by microwave.Put the tea sample into the metering heating cup 1001 and add water at 60 - 65°C.

[0026] In the present invention, such as Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown in the figure, a storage cylinder 41 and a temperature and humidity sensor 41a arranged inside the storage cylinder 41 are provided in the tea storage room 40. The bottom of the storage cylinder 41 is conical. A vibrator 42 is provided on the outer wall of the bottom of the storage cylinder 41. A delivery pipe 43 is sleeved on the outlet of the storage cylinder 41. The upper end of the delivery pipe 43 is slidably sleeved on the outlet of the storage cylinder 41. The lower end of the delivery pipe 43 extends into a delivery cylinder 203. A blocking valve plate 204 is hinged on the outlet end of the delivery cylinder 203. A support assembly for supporting the storage cylinder 41 is provided on the inner wall of the tea storage room 40. The support assembly includes an annular support platform 420 and a U-shaped support beam 421. The annular support platform 420 is arranged along the inner wall of the tea storage room 40. A pair of U-shaped support beams 421 for supporting the bottom of the storage cylinder 41 are horizontally and fixedly arranged on the lower surface of the annular support platform 420 between the inner walls on both sides of the tea storage room 40. A support arm 44 is provided on the outer wall of the storage cylinder 41. A first buffer spring 45 is vertically arranged between the lower surface of the support arm 44 and the surface of the annular support platform 420. The support arm 44 on the outer wall of the storage cylinder 41 is arranged on the annular support platform 420 through the first buffer spring 45. Second buffer springs 422 and delivery push rods 423 are respectively arranged on both sides of the bottom of the U-shaped support beam 421 along the extending direction of the delivery pipe 43. An annular support plate 424 is sleeved on the outer wall of the delivery pipe 43 on the side close to the outlet of the storage cylinder 41. The lower end of the second buffer spring 422 and the output end of the delivery push rod 423 are respectively connected to the edges of the annular support plate 424 on both sides of the delivery pipe 43. The upper end of the second buffer spring 422 and the fixed end of the delivery push rod 423 are respectively fixed on the bottom of the U-shaped support beam 421 on both sides of the outlet of the storage cylinder 41. A sealing cover 40a for sealing and covering the top port of the storage cylinder 41 is provided on the top of the tea storage room 40. A tea inlet 40b is provided on the sealing cover 40a. Sealing buffer cotton 40c is provided on the inner wall edge of the sealing cover 40a. The tea sample to be measured and detected is fed into the storage cylinder 41 from the tea inlet 40b. The temperature and humidity sensor 41a is used to detect the temperature and humidity of the storage environment of the tea sample in the storage cylinder 41. The collected environmental humidity of the storage cylinder 41 is the temperature and humidity of the tea sample. Affected by the moisture content of the tea sample itself, it can reflect the humidity of the tea sample in the current measurement and detection environment, so as to simultaneously master the temperature and humidity conditions of the measured and detected tea sample. The measured and detected temperature and humidity electrical signals are transmitted to the controller of the detection control board 300 for quantization processing and analysis to obtain the temperature and humidity values and display them through the touch display screen 23. At the same time, a gas sensor can also be arranged in the storage cylinder 41 to collect and measure and detect the smell of the tea sample in the current measurement and detection environment, so as to reflect the processing quality of the tea.When it is necessary to measure and detect the parameters of the tea sample in the storage cylinder 41, start the measurement and detection device and control the conveying push rod 423 and the vibrator 42 through the controller on the detection control board 300. The vibrator 42 vibrates the storage cylinder 41, so that the storage cylinder 41 performs buffered vibration on the first buffer spring 45 through its support arm 44, causing the tea sample to fall from the outlet of the storage cylinder 41 into the conveying pipe 43 and slide along the conveying pipe 43. The conveying push rod 423 pushes on the annular support plate 424 on the conveying pipe 43, causing it to drive the conveying pipe 43 to slide back and forth between the outlet of the storage cylinder 41 and the conveying cylinder 203. The second buffer spring 422 limits and buffers the stroke of the conveying pipe 43 and simultaneously generates vibration. When the conveying pipe 43 slides out from the outlet end of the conveying cylinder 203, it pushes the blocking valve plate 204 to open, and the conveying pipe 43 extends downward obliquely to the upper part of the mouth of the measurement and detection box 200, so that the tea sample to be measured and detected falls from the conveying pipe 43 into the measurement and detection box 200. Then, start the second parameter detection component 202 to perform measurement and detection on the tea sample in the measurement and detection box 200.

[0027] In the present invention, as Figure 5As shown in the figure, a servo motor 24 is arranged in the second metering and detection chamber 20 below the placement groove 201. A driving gear 25 is arranged on the output shaft of the servo motor 24. A vertically downward extending rotating shaft 2000a is arranged at the center of the rotating support turntable 2000. A driven gear 2000b meshing with the driving gear on the output shaft of the servo motor 24 is arranged at the lower end of the rotating shaft 2000a. Guide wheels 201a are arranged at the edge of the lower surface of the rotating support turntable 2000. A guide support rail 201b for supporting the rotation of the guide wheels is arranged at the bottom of the placement groove 201. The second parameter detection assembly 202 includes a support shield 2020 arranged directly above the metering and detection box 200 and fitting with the mouth of the metering and detection box 200, and image shooting assemblies 2021 arranged on both sides of the center inside the support shield 2020. A second electric push rod 2022 is vertically arranged above the outer wall of the top end of the support shield 2020. The upper end of the second electric push rod 2022 is fixed at the top end of the second metering and detection chamber 20. The lower end of the second electric push rod 2022 is drivingly connected to the outer wall of the top end of the support shield 2020. Pulse irradiation lamps 2023 are respectively arranged on both sides of the inner wall of the support shield 2020 and on both sides of the image shooting assembly 2021. The pulse irradiation lamps 2023 are infrared spectrum irradiation lamps. The image shooting assembly 2021 is a CMOS sensor and / or an ICCD sensor (Intensified charge - coupled device), preferably a combination of an ICCD sensor and a CMOS sensor. Electrode heads 2024 are symmetrically arranged on both sides and extend into the metering and detection box 200 as the support shield 2020 moves downward near the inner wall of the edge of the support shield 2020. The electron bombardment source voltage of the electrode heads 2024 is 40 - 70 eV. When the tea sample falls into the metering and detection box 200, the servo motor 24 arranged in the second metering and detection chamber 20 below the placement groove 201 is started. The servo motor 24 drives the driven gear 2000b through the driving gear 25 and drives the rotation of the rotating shaft 2000a. During the rotation of the rotating shaft 2000a, the rotating support turntable 2000 is driven to rotate, so that the conveying pipe 43 continuously distributes the tea samples in the metering and detection box 200. After loading the tea samples, the metering and detection parameters of the second parameter detection assembly 202 are set through the touch display screen 23, and then the second electric push rod 2022 is started to push the support shield 2020 downward to the edge of the mouth of the metering and detection box 200. The mouth of the metering and detection box 200 does not contact the edge of the mouth of the support shield 2020 (a gap is provided).During the rotation of the rotary support turntable 2000, the image capture component 2021 is activated to collect images of tea samples. The CMOS sensor is used to collect color images of tea samples, and the collected color images are transmitted to a computer through the data interface 302 for analysis of the color images of the sample tea. By comparing the analyzed tea sample images with the standard tea color image data in the database, it is determined whether the color quality of the tea during processing meets the requirements, and thus the quality and grade are judged based on the color. The ICCD sensor is used to collect spectral images of tea samples, and the collected images are transmitted to a computer through the data interface 302 for analysis of the spectral images of the sample tea. The ICCD sensor has high resolution and a wide range of spectral performance detection, and can simultaneously collect the spectra of multiple metal elements. The pulsed irradiation lamp 2023 is irradiated on the tea sample, and the laser generated by the pulsed irradiation lamp 2023 irradiates the tea sample to generate metal-induced ions in the tea. The ICCD sensor obtains the induced spectral data of the metal ions excited by the tea sample and transmits it to the computer through the data interface 302 for spectral analysis to obtain the characteristic wavelengths of heavy metals corresponding to the spectral image data, thereby quickly measuring and detecting the heavy metal element content of the tea sample. In order to accelerate the generation of metal-induced ions in the tea sample, the electrode head 2024 on the support shield 2020 extends into the metering and detection box 200 and collides with the tea sample during the uniform clockwise or counterclockwise rotation of the tea sample on the rotary support turntable 2000. During the process of the electrode head 2024 stirring the tea sample, metal-induced ions are generated under the voltage excitation of the electrode head 2024 on the tea sample, so that the metal-induced ions can be completely and quickly generated, improving the reliability and stability of the detection of heavy metal elements in tea.;

[0028] Combined with the present invention Figures 1 to 5, the metrological detection process of a multi-parameter metrological detection device for Liubao tea leaves of the present invention will be further elaborated. First, the tea leaf samples to be metrologically detected are fed into the storage cylinder 41 from the tea leaf inlet 40b. The metrological detection device is started by the control button 22, and the metrological detection parameters of the tea leaf samples are set using the touch display screen 23. The temperature and humidity sensor 41a is used to detect the temperature and humidity of the storage environment of the tea leaf samples in the storage cylinder 41, so as to reflect the humidity of the tea leaf samples in the current metrological detection environment. At the same time, a gas sensor can also be set in the storage cylinder 41 to collect and metrologically detect the odor of the tea leaf samples in the current metrological detection environment, so as to reflect the odor quality emitted during tea processing; Then, the metrological detection device is started and the conveying push rod 423 and the vibrator 42 are controlled by the controller on the detection control board 300. The vibrator 42 vibrates the storage cylinder 41, causing the tea leaf samples to fall from the outlet of the storage cylinder 41 into the conveying pipe 43 and slide along the conveying pipe 43. When the conveying pipe 43 slides out from the outlet end of the conveying cylinder 203, it pushes the blocking valve plate 204 to open, and the conveying pipe 43 extends downward obliquely to the upper part of the mouth of the metrological detection box 200. The tea leaf samples to be metrologically detected fall from the conveying pipe 43 into the metrological detection box 200, and the rotating support turntable 2000 is driven to rotate, so that the tea leaf samples are evenly distributed in the metrological detection box 200. Then, the second parameter detection component 202 is started to perform metrological detection on the tea leaf samples in the metrological detection box 200. Secondly, after the tea leaf samples are filled in the metrological detection box 200, the weight of the tea leaf samples filled in the metrological detection box 200 is obtained through the second weighing sensor 2001. The second electric push rod 2022 is started to push the support shield 2020 downward to the edge of the mouth of the metrological detection box 200. During the rotation of the rotating support turntable 2000, the image capturing component 2021 is started to collect the images of the tea leaf samples, and at the same time, the color image and spectral image data of the tea leaves are obtained, so as to calculate the heavy metal content from the total weight of the sample tea leaves. The collected spectrum and color image are compared with the Liubao tea spectrum to determine its processing and production quality;Finally, after the second parameter detection component 202 finishes detecting the tea sample, turn off the working power supply of the second parameter detection component 202, stop the rotation of the rotary support turntable 2000, open the sealing door 21 and the L-shaped plug cover 102 respectively, then take out the metering detection box 200 from the second metering detection chamber 20, and then pour the sample tea in the metering detection box 200 into the metering heating cup 1001. Add the required water at 60-65 °C to the metering heating cup 1001, and place the metering heating cup 1001 from the placement hole 104a of the weighing support plate 104 into the heating cavity 106 of the heating base 100. Then use the L-shaped plug cover 102 to seal the metering heating cup 1001 in the first metering detection chamber 10. Then, detect the total mass of the tea and water contained in the metering heating cup 1001 through the first weighing sensor 105. Then, push the detection probe 1011 downward through the first electric push rod 1002, so that the detection probe 1011 extends into the metering heating cup 1001, and heat the metering heating cup 1001 through the heating cavity 106 of the heating base 100 for 10 min - 20 min and then stop heating, so that its temperature is maintained between 80-90 °C. The detection probe 1011 detects in real time the concentration parameters of the total dissolved solids, tea polysaccharides, tea polyphenols, etc. in the tea water in the metering heating cup 1001, so that the tea fragrance is completely soaked out. Under the irradiation of the ultraviolet irradiation lamp 103a, detect the tea smell parameters emitted from the metering heating cup 1001 through the smell sensor 103; the photons emitted by the ultraviolet irradiation lamp 103a collide with the gas molecules volatilized during soaking to generate an ion beam, accelerating the diffusion rate of the ion beam in the first metering detection chamber 10, improving the detection speed and efficiency.

[0029] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
