Description

Technical Field

[0001] The present application relates to the technical field of traditional Chinese medicine pesticide residue detection, and particularly relates to a traditional Chinese medicine pesticide residue detection device. Background Art

[0002] Gardenia jasminoides Ellis is a high-value traditional Chinese medicine, and the detection of its pesticide residues is a key link to ensure product safety. Traditional detection methods mostly use chemical analysis methods, which have the defects of destroying samples and long time consumption; in recent years, the technology of combining hyperspectral imaging and Raman spectroscopy has been gradually applied to the detection of agricultural products due to its non-destructive and strong traceability characteristics. However, there are still significant technical bottlenecks in fruits with complex shapes such as Gardenia jasminoides Ellis: Since the sepals of Gardenia jasminoides Ellis are long and narrow lanceolate and surround the depression at the top of the fruit, and the surface of the sepals is densely covered with villi (300 - 500 roots / mm 2 ), the specific surface area is 3 times that of the pericarp, and the adsorption amount of fat-soluble pesticides (such as cypermethrin) can reach 5 - 8 times that of the pericarp; moreover, the thickness of the wax layer of the sepals (20 - 50 μm) hinders the degradation of pesticides, and the residual half-life is extended by 2 - 3 times. The connection between the sepals and the fruit stalk is the key area for pest control (such as the habitat of aphids), and the concentration of organophosphorus pesticides (such as chlorpyrifos) here is 2 - 4 times higher than that of the pericarp; therefore, the pesticide residues on the sepals need to be detected with emphasis. However, the sepals of Gardenia jasminoides Ellis have a large bending amplitude when unfolded, that is, when the sepals are close to a straight state, some areas of the sepals face downward, and the downward areas are difficult to be scanned and detected, and block the scanning of the connection between the sepals and the fruit stalk. Summary of the Invention

[0003] In order to overcome the defect that the sepals of Gardenia jasminoides Ellis have a large bending amplitude when unfolded, resulting in difficulty in scanning and detecting the downward areas of the sepals and blocking the scanning of the connection between the sepals and the fruit stalk, the present invention provides a traditional Chinese medicine pesticide residue detection device.

Detailed implementation manners

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Embodiment 1

[0029] A pesticide residue detection device for traditional Chinese medicinal materials, as Figures 1 - 5 shown, includes a detection table 1 and a scanner 2; two scanners 2 are fixedly connected to the detection table 1; a hyperspectral imaging scanning head and a Raman spectroscopy scanning head are connected to each scanner 2;

[0030] It further includes a motor 3, a fixed cylinder 4, a rubber ring 5, a first connecting rod 6 and a limiting ring 7; the motor 3 is bolted to the detection table 1; the output shaft of the motor 3 is fixedly connected to the fixed cylinder 4; one of the scanners 2 is located behind the fixed cylinder 4; the other scanner 2 is located above the fixed cylinder 4; the rubber ring 5 is fixedly connected to the fixed cylinder 4; the detection table 1 is connected to the first connecting rod 6 through a connecting seat in a damping sliding manner; the first connecting rod 6 is connected to the limiting ring 7 through a connecting plate.

[0031] In order to facilitate the insertion of the medicinal materials into the center of the rubber ring 5, the upper part of the central ring of the rubber ring 5 is arranged in a horn shape.

[0032] In order to fix Gardenia jasminoides Ellis more firmly, a plurality of grooves for accommodating the edges of Gardenia jasminoides Ellis are formed on the inner wall of the limiting hole in the center of the rubber ring 5.

[0033] In order to avoid damaging the calyx of Gardenia jasminoides Ellis, the cross-section of the limiting ring 7 is circular.

[0034] In order to adapt to the treatment of different medicinal materials with calyx, the first connecting rod 6 and the limiting ring 7 are detachably connected.

[0035] It further includes an elastic rod 22; a plurality of elastic rods 22 are annularly and equidistantly connected to the inner ring surface of the limiting ring 7.

[0036] Taking Figure 1 the perspective as a reference, the side where the label detection table 1 is located is the front side, and the side where the label scanner 2 is located is the rear side.

[0037] During use, insert the root of Gardenia jasminoides Ellis into the central hole of the rubber ring 5. At this time, the fruit top of Gardenia jasminoides Ellis with sepals faces upward, and the rubber ring 5 is expanded to apply extrusion pressure to the root of Gardenia jasminoides Ellis to stably fix Gardenia jasminoides Ellis. Then, close the airtight door on the detection table 1 to avoid the influence of external environmental light on the detection. Then, first perform hyperspectral imaging scanning (400 - 1000 nm) on the side and the top concave part of Gardenia jasminoides Ellis through the hyperspectral imaging scanning head on the scanner 2 behind and above the fixed cylinder 4. During detection, drive the fixed cylinder 4, the rubber ring 5 and Gardenia jasminoides Ellis to slowly rotate through the motor 3 to perform scanning work in all aspects. After hyperspectral imaging scanning, manually open the airtight door on the detection table 1, and then manually rotate the scanner 2 so that the Raman spectroscopy scanning head on the scanner 2 is aligned with Gardenia jasminoides Ellis. Then, manually use tools such as a spray bottle to spray gold nanoparticles with a particle size of 48 nm to 52 nm on the surface of Gardenia jasminoides Ellis as a surface-enhanced Raman spectroscopy substrate, and then perform local enhanced Raman spectroscopy detection. After detection, perform data fusion preprocessing (SNV + Svitzky-Goly filtering), and finally perform convolutional neural network classification (output categories such as organophosphorus / pyrethroid) to detect pesticide residues on the side of Gardenia jasminoides Ellis.

[0038] When scanning and detecting the side of Gardenia jasminoides Ellis, the pesticide residues on the sepals can be detected simultaneously. The upward-facing part of the sepals is scanned and detected by the scanner 2 above. However, there is a situation where the sepals of Gardenia jasminoides Ellis are bent too much. That is, when the sepals are close to a straight state, some areas of the sepals face downward, and the downward areas are difficult to be scanned and detected by the two scanners 2, and they block the scanner 2 from scanning the connection between the sepals and the fruit stalk. Therefore, a limiting ring 7 is provided directly above the rubber ring 5. When inserting Gardenia jasminoides Ellis onto the rubber ring 5, as Figure 5 shown, let Gardenia jasminoides Ellis pass through the limiting ring 7 from top to bottom and then insert it onto the rubber ring 5. After insertion, the sepals of Gardenia jasminoides Ellis are located inside the limiting ring 7. Then, manually push the first connecting rod 6 upward to move the limiting ring 7 upward to push the unfolded sepals upward, avoiding the sepals from being bent too much and affecting the detection.

[0039] Considering that due to the various shapes of the sepals of Gardenia jasminoides Ellis, there is a situation where the upper parts of two adjacent sepals of Gardenia jasminoides Ellis are close to each other, and the close parts of the sepals cannot be scanned and detected by the scanner 2, resulting in detection dead angles. Therefore, a number of elastic rods 22 are connected annularly and equidistantly on the inner ring surface of the limiting ring 7. After Gardenia jasminoides Ellis passes through the limiting ring 7 from top to bottom and is inserted onto the rubber ring 5, the root of each sepal of Gardenia jasminoides Ellis is located between two adjacent elastic rods 22. Then, when controlling the limiting ring 7 to move upward to push the sepals, the elastic rods 22 on the limiting ring 7 move upward together to separate and smooth out the sepals that are close to each other, avoiding detection dead angles.

[0040] It should be noted that in addition to detecting Gardenia jasminoides Ellis, the present invention can also detect other medicinal materials with or without sepals. The detection operation is the same. Place the medicinal material on the rubber ring 5 for fixation, and then detect it through two scanners 2. For the medicinal material with sepals, after fixation, the sepals are restricted and adjusted by the limit ring 7. Specifically, the limit ring 7 is detachable and can be replaced with different diameters to adapt to different medicinal materials with sepals.

[0041] Embodiment 2

[0042] On the basis of Embodiment 1, as Figures 1 - 9 shown, it further includes a collar 8, a sleeve 9, a drum airbag 10, a second connecting rod 11, an air pipe 12, an airbag 13, a spring 14, a first L-shaped rod 15, a pneumatic push rod 16 and a second L-shaped rod 17; the first connecting rod 6 is composed of a sliding part and a fixed part. The diameter of the sliding part is smaller than that of the fixed part. The fixed part is slidably connected to the connecting seat on the detection table 1 in a damping manner. A collar 8 is slidably connected to the sliding part of the first connecting rod 6 and a sleeve 9 is sleeved thereon; the collar 8 is rotatably connected to the sleeve 9; a drum airbag 10 is fixedly connected to the outer ring surface of the sleeve 9; a second connecting rod 11 is welded to the sleeve 9; an air pipe 12 is fixedly connected to the second connecting rod 11; the lower part of the air pipe 12 communicates with an airbag 13; the drum airbag 10 is communicated with the air pipe 12 through a connecting hose; a spring 14 is fixedly connected between the lower side of the collar 8 and the fixed part of the first connecting rod 6; two first L-shaped rods 15 are welded to the collar 8; a pneumatic push rod 16 is fixedly connected to the fixed part of the first connecting rod 6; the drum airbag 10 is communicated with the pneumatic push rod 16 through a connecting hose; two telescopic ends of the pneumatic push rod 16 are respectively fixedly connected with a second L-shaped rod 17, and the second L-shaped rod 17 is in an inverted state.

[0043] In order to facilitate the insertion of the airbag 13 into the center of the sepal, the airbag 13 is set to be flat.

[0044] In order to facilitate the airbag 13 to maintain a vertical state for easy insertion into the center of the sepal, a fixing piece 1301 is arranged in the middle of the airbag 13. The fixing piece 1301 is fixedly connected to the air pipe 12 and penetrates through the airbag 13.

[0045] It further includes a positioning plate 21; a positioning plate 21 is welded to the first connecting rod 6.

[0046] In this embodiment, as Figure 9 shown, in the initial state, the airbag 13 is located on the side of the limit ring 7:

[0047] During the detection process, there is a situation where some sepals of the gardenia are directly above the top depression of the gardenia, which affects the scanning detection of the depression by the scanner 2. Therefore, when it is observed manually that some sepals of the gardenia to be detected are directly above the top depression of the gardenia, first manually hold the air bag 10, and then drive the air bag 10 and its associated components upward, so that the first connecting rod 6 slides upward in a damped manner on the fixed cylinder 4, making the limiting ring 7 move away from the rubber ring 5, so that there is enough space between the rubber ring 5 and the limiting ring 7 to place the gardenia, and then place the gardenia in the rubber ring 5. Then, with the view from top to bottom as the reference, manually rotate the air bag 10 clockwise. The air bag 10 drives the sleeve 9 to rotate on the collar 8, and the second connecting rod 11 rotates with the sleeve 9 until it contacts the positioning plate 21. At this time, the air bag 13 is exactly directly above the center of the limiting ring 7. Through the positioning effect of the positioning plate 21 on the second connecting rod 11, the air bag 13 can be quickly rotated to directly above the center of the limiting ring 7 by the operator, improving the efficiency. After that, pinch the air bag 10, and the gas in the air bag 10 is filled into the pneumatic push rod 16 through the through pipe, forcing the telescopic end in the pneumatic push rod 16 to drive the two L-shaped rods 17 to move away from each other. Then, the operator holds the air bag 10 and its associated components and moves downward. The collar 8 moves downward to compress the spring 14, and then release the air bag 10, but keep the height of the air bag 10 unchanged. The air bag 10 expands and restores to its original state due to its own elasticity, and the gas in the pneumatic push rod 16 returns to the air bag 10. The L-shaped rods 17 move toward each other and reset to contact the first L-shaped rod 15, thereby limiting the first L-shaped rod 15, as Figure 6 shown; then, the operator holds the air bag 10 and drives the air bag 10 and its associated components downward, so that the first connecting rod 6 slides downward in a damped manner on the fixed cylinder 4, as Figure 8As shown, the air bag 13 is inserted into the center of the sepal (the top depression of the yellow gardenia), and the limiting ring 7 is located at the outer periphery of the upper part of the sepal. Then, the air bag 10 is manually pinched, and the air bag 13 is inflated after being pinched. The air bag 13 is inflated and expanded, and the sepal is stretched outward into a trumpet shape. At this time, the sepal moves to the periphery of the limiting ring 7, and the limiting ring 7 blocks the sepal to prevent the sepal from being located directly above the top depression of the yellow gardenia, affecting the scanning detection of the depression by the scanner 2; then continue to pinch the air bag 10, at this time the air bag 13 has expanded to the limit, and the gas in the air bag 10 will be filled into the pneumatic push rod 16 through the through pipe, forcing the telescopic part of the pneumatic push rod 16 to The two L-shaped rods 17 are driven by the end to move away from each other, so that the two L-shaped rods 17 are separated from the corresponding L-shaped rods 15, so that the L-shaped rods 15 are no longer limited by the L-shaped rods 17, and the spring 14 rebounds to give the ring 8, the sleeve 9 and the airbag 10 an upward thrust. Under the action of this thrust, the airbag 10 and its associated components are manually held and moved upward, so that the airbag 13 moves to the bottom of the limiting ring 7, and then, based on the view from top to bottom, the airbag 10 is manually rotated counterclockwise to rotate the airbag 13 to the side of the limiting ring 7 to avoid the airbag 13 affecting the scanning detection; and then the top of the gardenia can be scanned and detected by the scanner 2 above.

[0048] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
