[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0033] Referring to the attached Figure 1 - attached Figure 10 , a plant popular science specimen detection device, including a box body 1. Both ends of the box body 1 are open structures. Two groups of ironing mechanisms are symmetrically installed up and down inside the box body 1. The ironing mechanism includes two rollers 2 rotatably installed between the inner walls on opposite sides of the box body 1. A water-absorbing cotton belt 3 is sleeved on the outer surfaces of the two rollers 2. A gap for the leaf specimen to pass through is left between the two water-absorbing cotton belts 3 arranged symmetrically up and down; a heat conduction plate 4 is fixedly installed between the inner walls on opposite sides of the box body 1. The lower surface of the heat conduction plate 4 is attached to the inner side of the water-absorbing cotton belt 3. An electric heating plate 5 that can slide up and down is also installed between the inner walls on opposite sides of the box body 1. A slider is fixedly installed on the side of the electric heating plate 5. Sliding grooves matching the slider are opened on the inner walls on opposite sides of the box body 1. The slider is slidably installed on the inner wall of the sliding groove; a plurality of magnetic blocks are installed on the adjacent side of the electric heating plates 5 arranged up and down, and the magnetic poles of the two relatively arranged magnetic blocks are arranged in opposite directions, so that the two electric heating plates 5 can be attracted to each other through the magnetic blocks and attached to the heat conduction plate 4; the electric heating plate 5 is arranged on the side of the heat conduction plate 4 away from the box body 1. A feeding platform 8 and a detection platform 9 are respectively fixedly installed at both ends of the box body 1. A detector 10 is fixedly installed at the end of the box body 1 close to the detection platform 9. A driving mechanism is installed between the box body 1 and one of the rollers 2. A synchronization component is installed between the two ironing mechanisms. The synchronization component includes two synchronization gears 33 respectively fixedly installed at the rotation centers of the corresponding two rollers 2 in the two groups of ironing mechanisms. The two synchronization gears 33 are meshed with each other.

[0034] When it is necessary to detect the plant specimen, start the stepping motor 13 and the electric heating plate 5, so that the output end of the stepping motor 13 drives the transmission tube 16 to rotate through the drive shaft 15, so that the transmission tube 16 can drive the second friction disk 17 to rotate. At the same time, the heat generated by the heating of the electric heating plate 5 will be transferred to the heat conduction plate 4, so that the heat conduction plate 4 can subsequently cooperate with the water-absorbing cotton belt 3 to iron the leaf specimen, remove the excess water on the surface of the leaf specimen, and flatten the leaf, which helps to clearly observe details such as the shape, vein and edge of the leaf during the detection process using the detector 10.

[0035] In this embodiment, the driving mechanism includes a mounting plate 12 fixedly mounted on the outer surface of one side of the box body 1, a stepper motor 13 is fixedly mounted on the outer surface of the mounting plate 12, the output end of the stepper motor 13 passes through the outer surface of the mounting plate 12 and is fixedly mounted with a drive shaft 15, the outer surface of the drive shaft 15 is sleeved with a transmission tube 16, the transmission tube 16 and the drive shaft 15 are installed through a spline transmission, a second friction disc 17 is fixedly mounted on one end of the transmission tube 16 near the box body 1, a first friction disc 14 is fixedly mounted on the rotation center of one of the rollers 2 near the second friction disc 17, and the first friction disc 14 is fixedly mounted on the outer surface of the drive shaft 15. The second friction disc 17 is arranged on the same axis. A temperature monitoring mechanism is installed between the two heat conducting plates 4 in the two sets of ironing mechanisms. The temperature monitoring mechanism includes a bellows 6 embedded in the two heat conducting plates 4. A piston tube 7 is fixedly installed on the outer surface of the box body 1. A baffle is fixedly installed on the end of the piston tube 7 away from the box body 1. The two bellows 6 are connected to the interior of the piston tube 7. The interior of the piston tube 7 and the two bellows 6 are filled with mercury. A movable plug 23 is slidably installed inside the piston tube 7. A piston rod 24 is fixedly installed on the outer surface of the movable plug 23 away from the box body 1. The piston rod 24 is fixedly installed on the outer surface of the movable plug 23 away from the box body 1. 4 penetrates the outer surface of the baffle and is slidably installed therewith. A toggle assembly is installed between the piston rod 24 and the transmission tube 16. The toggle assembly includes a fixing frame 27 fixedly installed on the outer surface of the box body 1. A rotating rod 28 is rotatably installed on the outer surface of the fixing frame 27. A guide rod 25 is fixedly installed on the outer surface of the end of the piston rod 24 away from the movable plug 23. The outer surface of the guide rod 25 near the end of the piston tube 7 is penetrated to form a rectangular opening for the piston rod 24 to pass through. The upper surface of the rotating rod 28 near the end of the piston rod 24 is penetrated to form a first guide groove 30 matching the guide rod 25. The guide rod 25 and the first guide groove 30 are aligned with each other. The inner wall is slidably installed, and the outer surface of the transmission tube 16 is sleeved with a moving ring 20. A shift rod 22 is fixedly installed on the outer periphery of the moving ring 20. A second guide groove 29 is penetrated through the upper surface of the rotating rod 28 near one end of the moving ring 20. The shift rod 22 is slidably installed on the inner wall of the second guide groove 29. A connecting assembly is installed between the moving ring 20 and the second friction disk 17. The connecting assembly includes a connecting snap ring 19 rotatably installed on the outer surface of the second friction disk 17 near the transmission tube 16. A connecting spring 21 is fixedly installed between the connecting snap ring 19 and the moving ring 20. The connecting spring 21 is sleeved on the outside of the transmission tube 16.

[0036] When the heating plate 5 heats the heat conducting plate 4, the mercury in the corrugated pipe 6 embedded inside the heat conducting plate 4 will expand due to heat, causing the expanded mercury to enter the piston pipe 7 and push the movable plug 23 outwards, enabling the movable plug 23 to push the piston rod 24 and the guide rod 25 to move outwards. Since the guide rod 25 is slidably installed in the first guide groove 30 formed on the rotary rod 28, and the rotary rod 28 is rotatably installed on the outer side of the box body 1 through the fixed frame 27, when the piston rod 24 moves outwards, it can push the rotary rod 28 through the guide rod 25 and the first guide groove 30, so that the other end of the rotary rod 28 can push the moving ring 20 towards the first friction disk 14 through the second guide groove 29 and the toggle lever 22. When the moving ring 20 is pushed, it will apply a thrust to the second friction disk 17 through the connecting spring 21 and the connecting snap ring 19, causing the friction surface of the second friction disk 17 to contact the first friction disk 14, enabling the second friction disk 17 to drive the corresponding roller 2 to rotate through the first friction disk 14. Since the two corresponding rollers 2 in the two ironing mechanisms are installed through the meshing synchronous gears 33, the rollers 2 in the two ironing mechanisms can drive the water-absorbing cotton belt 3 to move relatively. When the water-absorbing cotton belt 3 moves, it indicates that the heat conducting plate 4 has reached the temperature required for ironing the leaf specimens. At this time, the leaf specimens pre-placed on the feeding platform 8 can be pushed between the two water-absorbing cotton belts 3, and the moving water-absorbing cotton belt 3 will bring the leaf specimens into the box body 1. When the leaf specimens move, the heat conducting plate 4 will iron them, flattening the leaf specimens and making the surface of the leaf specimens flat, which helps to clearly observe details such as the shape, vein, and edge of the leaves during the detection process using the detector 10.

[0037] In this embodiment, a spacing adjustment assembly is installed between the piston rod 24 and the two heating plates 5. The spacing adjustment assembly includes an extension rod 31 fixedly installed on the side of the heating plate 5. The extension rod 31 is rotatably installed with a rotating block 32 at the end away from the heating plate 5, and the end of the rotating block 32 away from the extension rod 31 is rotatably installed on the outer surface of the guide rod 25. A rectangular groove for the up-and-down movement of the extension rod 31 is penetrated through the outer surface of the box body 1.

[0038] When the temperature of the heat conducting plate 4 continues to rise, the piston rod 24 drives the guide rod 25 to continue moving outwards. The guide rod 25 will push the upper and lower heating plates 5 away from the heat conducting plate 4 through the rotating block 32 and the extension rod 31, reducing the heat transferred from the heating plates 5 to the heat conducting plate 4 and preventing the temperature of the heat conducting plate 4 from overheating and damaging the leaf specimens.

[0039] In this embodiment, two stripping plates 11 are symmetrically and fixedly installed vertically between the inner walls on the opposite sides of the box body 1 close to the detection platform 9. The outer surface of the stripping plate 11 away from the detection platform 9 is attached to the outer surface of the absorbent cotton belt 3. By attaching the sides of the two stripping plates 11 to the outer surface of the absorbent cotton belt 3, the stripping plates 11 can scrape off the leaf specimens adhered to the outside of the absorbent cotton belt 3, preventing the leaf specimens from adhering to the absorbent cotton belt 3.

[0040] In this embodiment, a return spring 26 is sleeved on the outer surface of the piston rod 24. The return spring 26 is arranged between the baffle plate and the movable plug 23.

[0041] After the electric heating plate 5 stops heating, the mercury in the corrugated pipe 6 and the piston pipe 7 will gradually cool and contract, enabling the return spring 26 to push the movable plug 23 to reset.

[0042] In this embodiment, an annular card slot 18 is formed on the outer surface of the second friction disc 17 close to the transmission pipe 16. The connecting snap ring 19 is rotatably installed on the inner wall of the annular card slot 18. When the moving ring 20 pulls the connecting snap ring 19 to move through the connecting spring 21, the connecting snap ring 19 can drive the second friction disc 17 to move through the connecting snap ring 19, separating the second friction disc 17 from the first friction disc 14.

[0043] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: When it is necessary to detect plant specimens, the stepping motor 13 and the electric heating plate 5 are started. The output end of the stepping motor 13 drives the transmission pipe 16 to rotate through the drive shaft 15, enabling the transmission pipe 16 to drive the second friction disc 17 to rotate. At the same time, the heat generated by the heating of the electric heating plate 5 will be transferred to the heat conducting plate 4, so that the heat conducting plate 4 can subsequently cooperate with the absorbent cotton belt 3 to iron the leaf specimens, removing the excess moisture on the surface of the leaf specimens and flattening the leaves, which helps to clearly observe details such as the shape, leaf veins, and edges of the leaves during the detection process using the detector 10.

[0044] When the electric heating plate 5 heats the heat conducting plate 4, the mercury embedded in the bellows 6 inside the heat conducting plate 4 will expand due to the heat, causing the expanded mercury to enter the piston tube 7 and push the movable plug 23 outward, so that the movable plug 23 can push the piston rod 24 and the guide rod 25 to move outward. Since the guide rod 25 is slidably installed with the first guide groove 30 provided on the rotating rod 28, and the rotating rod 28 is rotatably installed with the outer side of the box body 1 through the fixing frame 27, the piston rod 24 can push the rotating rod 28 through the guide rod 25 and the first guide groove 30 when moving outward, so that the other end of the rotating rod 28 can push the movable ring 20 toward the first friction disk 14 through the second guide groove 29 and the detent rod 22. When the movable ring 20 is pushed, it will apply a thrust to the second friction disk 17 through the connecting spring 21 and the connecting snap ring 19, so that the second friction disk 17 and the second friction disk 17 are connected. The friction surface of one friction disc 14 contacts, so that the second friction disc 17 can drive the corresponding roller 2 to rotate through the first friction disc 14. Since the two corresponding rollers 2 in the two sets of ironing mechanisms are installed through the meshing synchronous gears 33, the rollers 2 in the two sets of ironing mechanisms can drive the absorbent cotton belts 3 to move relative to each other. When the absorbent cotton belts 3 move, it means that the heat conduction plate 4 has reached the temperature required for ironing the leaf specimens. At this time, the leaf specimens pre-placed on the feeding platform 8 can be pushed between the two absorbent cotton belts 3, so that the moving absorbent cotton belts 3 bring the leaf specimens into the box 1. When the leaf specimens move, the heat conduction plate 4 will iron them, so that the leaf specimens can be flattened and the surface of the leaf specimens is flat, which helps to clearly observe the shape, veins, edges and other details of the leaves during the detection process using the detector 10;

[0045] The ironed leaf specimens will be transferred to the detection platform 9 so that the leaf specimens can be tested by the detector 10 and the detection information of the leaf specimens can be recorded for subsequent scientific popularization.

[0046] When the temperature of the heat conducting plate 4 continues to rise, the piston rod 24 will continue to push the rotating rod 28 to rotate, so that the connecting spring 21 provided on the movable ring 20 is gradually compressed, thereby preventing the rotating rod 28 from being unable to rotate and being stuck;

[0047] When the piston rod 24 drives the guide rod 25 to continue to move outward, the guide rod 25 will push the upper and lower heating plates 5 away from the heat conduction plate 4 through the rotating block 32 and the extension rod 31, reducing the heat transferred from the heating plate 5 to the heat conduction plate 4, and preventing the heat conduction plate 4 from overheating and scalding the leaf specimens.

[0048] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
