[0002] In recent years, the research and application of obtaining or enriching one or more active ingredients in plants with natural plant raw materials has received more and more attention. Natural plants contain complex ingredients, and the extracted extracts are mostly mixed liquids containing a large number of colloids, suspended particles, macromolecules, soluble components, solvents, etc. The extracts need to be finely separated and processed to remove the ineffective components and obtain the required active ingredients.

[0003] To extract the useful parts of the plant, in order to make the extracted parts meet the standards and quality requirements, it is necessary to test the items from the extraction. In this regard, the Chinese patent, announcement number: CN213780124U, proposes a plant extract detection device with good stability. The first hydraulic telescopic rod is started, and the first hydraulic telescopic rod moves forward with the telescopic plate inside the fixed plate. When the detection head at the front end of the first hydraulic telescopic rod moves to the top of the storage box, the second hydraulic telescopic rod drives the detection head to extend to the inside of the storage box for sampling. After the sampling is completed, the second hydraulic telescopic rod is retracted, and then the detection head is driven forward by the first hydraulic telescopic rod. When the detection head extends to the top of the detection plate, the second hydraulic telescopic rod drives the detection head to place the raw materials to be detected on the detection plate, so as to perform the detection.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0027] See also Figure 8 , a rapid detection method for plant extracts, comprising the following steps: Step 1: sampling, taking a certain amount of plant extract stock solution, and introducing the stock solution into a rapid detection device; Step 2: Install the test board on the rapid test device and adjust various test parameters; Step 3: The rapid detection device works to transfer the plant extract solution to the detection plate; Step 4: Let stand for 10-15 minutes and record the test results.

[0028] See also Figure 1-7The rapid detection device comprises a base 1, two vertical plates 4 fixedly mounted on the base 1 and arranged opposite to each other, and an assembly plate 5 fixedly mounted on the base 1. The base 1 is also provided with a box 2 for containing the original plant extract and a receiving platform 3, and the receiving platform 3 is used to place the detection plate; The rapid detection device also includes: A transverse plate 6 is movably disposed between the two vertical plates 4 and connected to a horizontal driving mechanism installed on the mounting plate 5, wherein the horizontal driving mechanism can drive the transverse plate 6 to move along the length direction of the base 1, and the horizontal driving mechanism is connected to a Maltese cross movement mechanism installed on the mounting plate 5; The extraction mechanism is installed on the transverse plate 6 and is connected to the Maltese cross movement mechanism through a transmission mechanism. The extraction mechanism is used to extract the plant extract liquid in the box 2 and discharge the plant extract liquid onto the detection plate after the transverse plate 6 moves above the detection plate.

[0029] In actual use, the collected plant extract is input into the box 2, and then the Maltese cross movement mechanism works to drive the transmission mechanism and the horizontal drive mechanism to move alternately; When the transmission mechanism moves, it will drive the extraction mechanism to move, and the extraction mechanism will extract the plant extract liquid in the box 2. Then, the horizontal driving mechanism moves to drive the transverse plate 6 to move along the length direction of the base 1, and until the transverse plate 6 moves to the top of the detection plate, the Maltese cross movement mechanism drives the extraction mechanism to move again. At this time, the extraction mechanism discharges the plant extract liquid onto the detection plate so that the plant extract liquid can be detected. Finally, the horizontal driving mechanism moves again to drive the transverse plate 6 to move and reset along the length direction of the base 1.

[0030] In summary, the rapid detection device has the functions of extracting, transferring and discharging the plant extract liquid, and various actions in the detection process are realized through the coordination of the mechanical structure, without the need to use multiple power elements to control each action separately. Therefore, the device has the advantage of low failure rate while ensuring the degree of automation, and is suitable for popularization and use.

[0031] Please refer again Figure 4 The Maltese cross movement mechanism includes a driving wheel 35, a first driven wheel 29 and a second driven wheel 30 rotatably mounted on one side of the mounting plate 5. A driving motor 28 is also mounted on the mounting plate 5. The rotating shaft of the driving wheel 35 is connected to the output end of the driving motor 28, the rotating shaft of the first driven wheel 29 is connected to the transmission mechanism, and the rotating shaft of the second driven wheel 30 is connected to the horizontal driving mechanism.

[0032] Please refer again Figure 1 , Figure 2 as well as Figure 6 , two cross bars 7 are fixedly provided between the two vertical plates 4, the transverse plate 6 is slidably provided on the two cross bars 7, the horizontal driving mechanism comprises two driving wheels 8 rotatably installed on the side of the assembly plate 5 facing the transverse plate 6 and a connecting member 9 connecting the two driving wheels 8, wherein the rotating shaft of one of the driving wheels 8 is connected to the rotating shaft of the second driven wheel 30 through a third transmission belt 36; Among them, the connecting member 9 is rollingly matched with the two driving wheels 8, and a driving column 10 is also provided on the connecting member 9. Two strip rods 601 are fixedly provided on the side of the transverse plate 6 facing the assembly plate 5. A gap is reserved between the two strip rods 601. The driving column 10 extends into the gap and is slidably connected with the two strip rods 601.

[0033] When the driving motor 28 drives the driving wheel 35 to rotate, so that the driving wheel 35 drives the second driven wheel 30 to rotate, the rotating shaft of the second driven wheel 30 will drive the driving wheel 8 to rotate through the third transmission belt 36, so that the connecting member 9 will drive the driving column 10 to move, and the driving column 10 will slide with the two strip rods 601, so that the transverse plate 6 moves on the two cross rods 7, that is, the transverse plate 6 moves from the top of the box body 2 to the top of the receiving platform 3, or the transverse plate 6 moves from the top of the receiving platform 3 to the top of the box body 2.

[0034] Please refer again Figure 5 and Figure 7 The extraction mechanism includes a cylinder 13 fixedly mounted on the transverse plate 6 and a piston disc 15 sealingly and slidably arranged inside the cylinder 13, the piston disc 15 is connected to a push-pull assembly mounted on the transverse plate 6, and the push-pull assembly is connected to the transmission mechanism; Among them, the cylinder 13 is also provided with a first one-way valve 16 and a second one-way valve 17, the first one-way valve 16 and the second one-way valve 17 are respectively connected to a first pipe fitting 19 and a conduit 18, the first pipe fitting 19 is sealingly and slidably fitted with a second pipe fitting 20, and the second pipe fitting 20 is connected to a sliding matching structure.

[0035] The push-pull assembly includes two guide posts 24 slidably mounted on the transverse plate 6, a guide plate 22 fixedly connected to the two guide posts 24, and a disc 14 rotatably mounted on the transverse plate 6, wherein the rotation axis of the disc 14 is connected to the transmission mechanism; A connecting rod 23 is connected between the disc 14 and the guide plate 22 , one end of the connecting rod 23 is rotatably connected to the guide plate 22 , and the other end is rotatably connected to the eccentric portion of the disc 14 , and a connecting column 21 is fixedly connected between the guide plate 22 and the disc 14 .

A through slot is disposed on the transverse plate 25 . The column 2701 passes through the through slot and is slidably connected to the transverse plate 25 . The through slot includes an inclined section 2501 and a straight section 2502 .

[0037] When the transverse plate 6 moves from the top of the box body 2 to the top of the receiving platform 3, the column 2701 will slide in the through groove. When the column 2701 slides in the inclined section 2501, the column 2701 will give way and drive the second pipe 20 to slide upward on the first pipe 19 through the driven plate 27. After the column 2701 slides into the straight section 2502, the second pipe 20 is located on the upper end surface of the box body 2, so as to avoid the second pipe 20 located below the liquid level of the plant extract to affect the movement of the transverse plate 6; On the contrary, when the transverse plate 6 moves from the top of the receiving platform 3 to the top of the box body 2, the column 2701 will move from the straight section 2502 to the inclined section 2501. When the column 2701 slides in the inclined section 2501, it will prompt the driven plate 27 to drive the second tube 20 to slide downward on the first tube 19, so that the second tube 20 extends below the liquid surface of the plant extract solution.

[0038] Whenever the first driven wheel 29 rotates, its rotation shaft will drive the disc 14 to rotate half a circle through the movement of the transmission mechanism. Correspondingly, the disc 14 drives the guide plate 22 and the connecting column 21 to drive the piston disc 15 to slide upward or downward in the cylinder 13 through the connecting rod 23. When the piston disc 15 slides upward in the cylinder 13, the first one-way valve 16 is turned on and the second one-way valve 17 is turned off, so that the plant extract in the box 2 is drawn into the cylinder 13; When the piston disc 15 slides downward in the cylinder 13 , the first one-way valve 16 is blocked, while the second one-way valve 17 is connected, so that the plant extract in the cylinder 13 is discharged and flows to the detection plate through the conduit 18 .

[0039] Please refer again Figure 1 , Figure 2 , Figure 5 as well as Figure 6 The transmission mechanism includes a rotating shaft 11 rotatably mounted between the two vertical plates 4 and a sleeve 12 rotatably mounted on the transverse plate 6, and the sleeve 12 is connected to the rotating shaft of the disc 14 through a second transmission belt 32; A limiting structure is provided between the sleeve 12 and the rotating shaft 11 , and the rotating shaft 11 is connected to a transmission shaft 33 rotatably mounted on the assembly plate 5 via a first transmission belt 31 , and the transmission shaft 33 is connected to the rotating shaft of the first driven wheel 29 via a bevel gear set 34 .

[0040] The limiting structure includes two strip-shaped protrusions 1101 formed on the outer wall of the rotating shaft 11 and two strip-shaped grooves 1201 provided on the inner wall of the sleeve 12 , and the strip-shaped grooves 1201 are adapted to the strip-shaped protrusions 1101 .

[0041] When the driving wheel 35 drives the first driven wheel 29 to rotate, the rotating shaft of the first driven wheel 29 will drive the transmission shaft 33 to rotate through the bevel gear set 34, and then the transmission shaft 33 will drive the rotating shaft 11 to rotate through the first transmission belt 31, and the rotating shaft 11 will drive the sleeve 12 to rotate through the two strip protrusions 1101 on its outer wall and the two strip grooves 1201 on the inner wall of the sleeve 12, so that the sleeve 12 drives the disc 14 to rotate half a circle through the second transmission belt 32, and accordingly, when the transverse plate 6 moves along the length direction of the base 1, it will drive the sleeve 12 to slide on the rotating shaft 11.
