Description

Technical Field

[0001] This utility model relates to the field of seedling cultivation and testing technology, specifically a colorimetric card box for the root vitality level of Populus simonii seedlings. Background Technology

[0002] In the field of seedling cultivation and physiological research, root vigor is a key indicator for measuring seedling growth and stress resistance. Colorimetric methods, such as comparing the color changes of soil or root extracts after a specific color reaction with a standard colorimetric card, are a common and rapid method for assessing the root vigor of Populus simonii seedlings.

[0003] However, traditional colorimetric operations mostly rely on manual visual comparison under natural light or fixed light sources, which has the following obvious shortcomings: First, fluctuations in ambient light intensity and color temperature can seriously affect the accuracy of color judgment, resulting in large subjective errors and low repeatability of results; Second, the colorimetric process is usually static, making it difficult to conveniently compare the color development differences between the sample and the colorimetric card under different simulated lighting conditions, thus limiting the comprehensiveness of the evaluation; Third, the entire comparison and recording process has a low degree of automation, low efficiency, and lacks effective isolation and standardized control of the observation process.

[0004] Therefore, in view of the problems of inaccurate colorimetry due to ambient light interference, single observation conditions, and insufficient automation in the above-mentioned existing technologies, there is an urgent need to design a colorimetric card box for the root vitality level of Populus simonii seedlings that can provide a stable and controllable observation environment and realize multi-condition colorimetry and automated assistance. Utility Model Content

[0005] The purpose of this invention is to provide a colorimetric card box for the root vitality level of Populus simonii seedlings, which has the advantages of providing a standardized closed observation environment, simulating multiple light conditions, and automating colorimetric analysis, thus solving the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The Populus simonii seedling root vigor level colorimetric card box includes a colorimetric box, a cover plate hinged to the upper edge of the colorimetric box, a protective box fixed to one end of the colorimetric box, a controller set on the side wall of the protective box, a first observation slot opened through the upper and lower ends of the cover plate respectively, a cross groove opened through one side of the cover plate, a shielding component slidably set on the inner wall of the cross groove, a first motor and a battery fixed to one end of the colorimetric box, a rotating rod rotatably installed on both sides of the inner wall of the colorimetric box, a light-emitting component and a camera component set on the rotating rod, two toothed rings fixed to the outer peripheral wall of the rotating rod, a first drive mechanism set on one side of the inner wall of the colorimetric box for engaging and rotating one of the toothed rings, a second drive mechanism set on the inner wall of one end of the colorimetric box for backup, an inner box slidably set on the bottom surface of the inner wall of the colorimetric box, multiple colorimetric cards set on the upper end of the inner box, a moving mechanism set in the colorimetric box for moving the inner box, and a color-changing mechanism set in the colorimetric box.

[0008] The shielding assembly is used to shield the first observation slot, and the second drive mechanism is used to rotate the other gear ring.

[0009] Preferably, handles are fixed to both sides of the colorimeter box, the handles are U-shaped, and the first motor and the battery are located inside the protective box.

[0010] It is worth noting that the U-shaped handle design makes it easy for operators to hold and carry the colorimetric card box, improving the portability of the equipment and adapting to the needs of on-site colorimetric testing of root samples from wild poplar seedlings.

[0011] Preferably, the shielding assembly includes a cross block slidably disposed on the inner wall of the cross groove, a through groove opened through one side of the cross block, a fixing rod fixed to the inner walls of both sides of the through groove, a shielding plate slidably disposed on the bottom surface of the inner wall of the through groove, and an arc-shaped block fixed to the upper end of the shielding plate. The arc-shaped block is arc-shaped, and the concave surface of the arc-shaped block is attached to the outer peripheral wall of the fixing rod. A second observation groove for observation is opened through both the upper and lower ends of the cross block.

[0012] It is worth noting that the cross block and cross groove slide together, which can quickly install and remove the shielding component. The shielding plate can slide along the through groove. With the cooperation of the arc block and the fixing rod, the position of the shielding plate can be quickly fixed, achieving precise shielding of the first observation slot. This can effectively isolate external light interference and ensure the stability of the colorimetric environment. The setting of the second observation slot allows the operator to conveniently observe the colorimetric process inside the colorimetric box without blocking external light.

[0013] Preferably, the illumination assembly includes a plurality of first fixing blocks fixed to the outer peripheral wall of the rotating rod and an LED light fixed to one end of the first fixing blocks near the center of the colorimeter box.

[0014] It is worth noting that multiple LED lights are evenly distributed on the rotating rod through the first fixing block, which can provide uniform and stable lighting inside the color box, avoiding the deviation of soil color from the color card caused by uneven local lighting intensity, thus improving the accuracy of color matching. LED lights have the advantages of low energy consumption, stable light emission, and long service life. When paired with battery power, they can meet the needs of long-term use in the field without external power supply, reducing equipment energy consumption.

[0015] Preferably, the camera assembly includes a plurality of second fixing blocks fixed to the outer peripheral wall of the rotating rod and a camera fixed to one end of the second fixing blocks near the center of the colorimeter box, with the second fixing blocks and the first fixing blocks being arranged alternately.

[0016] It is worth noting that the multiple cameras can capture images of the soil samples and color charts of the Populus simonii seedling roots from different angles, capturing more comprehensive and clearer color details. This avoids color deviation caused by shooting from a single angle, making it easier for operators to accurately compare the soil color with the color chart and improving the accuracy of the color comparison results. The second fixing block is staggered with the first fixing block, which can effectively prevent the lighting components and camera components from blocking each other, ensuring that the light from the LED light can smoothly illuminate the soil samples and color charts. At the same time, the cameras can clearly capture the shooting images without interference. The cameras rotate synchronously with the rotating rod, which can flexibly adjust the shooting angle to adapt to different placement positions of the soil samples and the movement of the inner box.

[0017] Preferably, the first drive mechanism includes a third motor fixed to one side of the inner wall of the colorimeter box and a first gear fixed to the output shaft of the third motor, wherein the first gear meshes with one of the gear rings.

[0018] It is worth noting that the first drive mechanism adopts a gear meshing transmission method, which has high transmission efficiency, smooth transmission and precise positioning. It can drive the first gear to rotate through the third motor, thereby driving the gear ring and rotating rod to rotate synchronously, realizing precise adjustment of the angle of the lighting component and the camera component. It is easy to operate and has high adjustment accuracy, and can quickly adjust the lighting component and the camera component to the optimal color matching angle, improving color matching efficiency and accuracy.

[0019] Preferably, the second drive mechanism includes a miniature electric cylinder fixed to the inner wall of one end of the colorimeter box, a movable block fixed to the output shaft of the miniature electric cylinder, a fourth motor fixed to the inner wall of the movable block, and a second gear fixed to the output shaft of the fourth motor. When the movable block moves, the second gear will mesh with another gear ring.

[0020] It is worth noting that the second drive mechanism, as a backup drive structure, can be quickly put into use when the first drive mechanism fails, avoiding the interruption of colorimetric work due to the failure of a single drive mechanism, improving the reliability and fault tolerance of the equipment, and ensuring the continuity of colorimetric work. The miniature electric cylinder can drive the movable block to move flexibly, realizing the rapid engagement and disengagement of the second gear and the gear ring. The switching is convenient and does not affect the normal use of the first drive mechanism. The fourth motor drives the second gear to rotate, also using gear meshing transmission to ensure smooth transmission and precise adjustment. It can realize the normal adjustment of the angle of the illumination component and the camera component, complementing the first drive mechanism and further improving the practicality and stability of the equipment.

[0021] Preferably, the moving mechanism includes a threaded column rotatably mounted on the inner walls of both ends of the colorimeter box, an internally threaded cylinder fixedly connected to the inner box, and a motor fixedly connected to one end of the colorimeter box. The output shaft of the motor passes through the side wall of the colorimeter box and is fixedly connected to one end of the threaded column. The outer peripheral wall of the threaded column and the inner wall of the internally threaded cylinder are adapted to each other, and the two sides of the inner box are in contact with the two sides of the inner wall of the colorimeter box.

[0022] It is worth noting that the motor drives the threaded column to rotate, which in turn drives the inner threaded cylinder and the inner box to move synchronously and smoothly through the threaded engagement. This allows for precise adjustment of the relative position of the colorimetric card and the soil sample, enabling the colorimetric card and the soil sample to be quickly aligned. This avoids colorimetric errors caused by misalignment and improves colorimetric accuracy. The two sides of the inner box fit against the inner wall of the colorimetric box, which guides and limits the movement of the inner box, preventing it from shaking or shifting during movement and ensuring smooth movement. It also prevents the colorimetric card from tipping over or becoming misaligned inside the inner box.

[0023] Preferably, the color-changing mechanism includes a first roller, a second roller, a third roller, a fourth roller, and a limiting roller rotatably mounted on the inner walls of both sides of the color-matching box. The outer peripheral walls of the first roller, the second roller, the third roller, and the fourth roller are collectively fitted with a transparent strip. At least one third observation groove is opened through the transparent strip. A second motor is fixedly connected to one side of the color-matching box, and the output shaft of the second motor passes through the side wall of the color-matching box and is fixedly connected to one end of the fourth roller.

[0024] It is worth noting that the color-changing mechanism can realize colorimetric detection under different colored light. The transparent strip can be preset with different colored filter areas. The second motor drives the fourth rotating roller to rotate, which drives the transparent strip to move synchronously. It can quickly switch the filter areas of different colors to the light path, so that the light of the light component passes through the filter area and shines on the soil sample and colorimetric card, simulating the color performance under different natural light conditions. It can comprehensively detect the change of soil color under different light conditions, avoid colorimetric deviation caused by single light conditions, and greatly improve the comprehensiveness and accuracy of colorimetric results. The limiting roller can limit the transparent strip to ensure that the transparent strip moves smoothly and avoids deviation and wrinkles. The setting of the third observation slot can ensure that the light can pass through smoothly, and at the same time facilitate the camera to capture the colorimetric image.

[0025] Preferably, the controller integrates a wireless communication module, which is electrically connected to the camera and is used to wirelessly transmit the image data captured by the camera to an external terminal.

[0026] It is worth noting that by integrating a wireless communication module (such as Bluetooth or Wi-Fi) into the controller and electrically connecting this module to the camera, real-time wireless transmission of colorimetric image data captured by the camera can be achieved. Operators no longer need to visually compare the data on the controller's screen on-site; instead, they can directly receive and store the image data on external terminals such as mobile phones, tablets, or computers, and use the pre-installed colorimetric analysis software on the terminal for rapid, quantitative color identification and grade determination. This design not only further reduces human visual error but also facilitates the establishment of an electronic root vitality database, enabling traceability and remote sharing of test results, and improving the efficiency and data management capabilities of batch field testing.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] 1. By setting up a shielding component including a cross-shaped block and a sliding shield, and cooperating with the cross-shaped groove and observation slot on the cover plate, a completely enclosed or controllably openable darkroom observation environment can be quickly constructed. This design effectively isolates the interference of variable ambient light, providing a stable and consistent optical background for comparing soil color with the colorimetric card, fundamentally solving the technical problems of large subjective errors and low repeatability of results in visual colorimetry caused by fluctuations in ambient light.

[0029] 2. By setting up a transparent strip containing multiple filter films and a color-changing mechanism that drives its movement, the built-in LED light source can be changed to light with different spectral characteristics in sequence. This design allows multiple natural lighting conditions (such as light at different times of day or light with a specific color temperature) to be simulated in one experiment, and enables rapid and continuous comparison of the color development state of the same sample under different "light environments".

[0030] 3. By integrating a moving mechanism driven by a motor and threaded column, and a rotating mechanism driven by a motor and gear ring that links the lighting and camera components, the positioning of the colorimetric card, the adjustment of the observation angle and the direction of illumination are automated. Combined with multi-camera image acquisition, the entire colorimetric process does not require manual opening of the cover, manual adjustment and visual judgment, which greatly improves the detection efficiency, reduces the intensity of operation and standardizes the detection process.

Please refer to [link / reference]. Figures 1-8 ;

[0042] The colorimetric card box for the root vitality level of Populus simonii seedlings includes a colorimetric box 1, a cover plate 2 hinged to the upper edge of the colorimetric box 1, a protective box 3 fixed to one end of the colorimetric box 1, a controller 4 disposed on the side wall of the protective box 3, first observation slots 7 respectively penetrating the upper and lower ends of the cover plate 2, a cross groove 5 penetrating one side of the cover plate 2, a shielding component slidably disposed on the inner wall of the cross groove 5, a first motor 10 and a battery 11 fixed to one end of the colorimetric box 1, and rotating rods 12 rotatably mounted on both sides of the inner wall of the colorimetric box 1. The light-emitting component and camera component are mounted on the rotating rod 12; two toothed rings 29 are fixed to the outer peripheral wall of the rotating rod 12; a first drive mechanism is mounted on one side of the inner wall of the colorimeter box 1 for engaging and rotating one of the toothed rings 29; a second drive mechanism is mounted on the inner wall of one end of the colorimeter box 1 for standby; an inner box 30 is slidably mounted on the bottom surface of the inner wall of the colorimeter box 1; multiple colorimeter cards 31 are mounted on the upper end of the inner box 30; a moving mechanism is mounted inside the colorimeter box 1 for moving the inner box 30; and a color-changing mechanism is mounted inside the colorimeter box 1.

[0043] The shielding assembly is used to shield the first observation slot 7, and the second drive mechanism is used to rotate the other gear ring 29.

[0044] In use, open cover 2 and place the soil from the root system of the poplar seedlings on the bottom of the inner wall of the colorimetric box 1. Turn on the camera component to photograph the soil. To avoid the influence of external light, cover 2 can be closed and the shielding component inserted into the inner wall of the cross groove 5. Then, turn on the camera component and the light component to compare the soil color with the colorimetric card 31 on the inner box 30. In use, the inner box 30 can also be moved using the moving mechanism. Turn on the first drive mechanism to adjust the position of the light component and the camera component. Turn on the color-changing mechanism so that the light component can compare the soil and the colorimetric card 31 under different light irradiation, thus increasing the accuracy of the color comparison.

[0045] In this embodiment, specifically: handles 9 are fixed to both sides of the colorimeter box 1. The handles 9 are U-shaped. The first motor 10 and the battery 11 are both located inside the protective box 3.

[0046] In this embodiment, specifically: the shielding assembly includes a cross block 6 slidably disposed on the inner wall of the cross groove 5, a through groove 17 penetrating one side of the cross block 6, a fixing rod 18 fixed to the inner walls of both sides of the through groove 17, a shielding plate 19 slidably disposed on the bottom surface of the inner wall of the through groove 17, and an arc-shaped block 20 fixed to the upper end of the shielding plate 19. The arc-shaped block 20 is arc-shaped, and the concave surface of the arc-shaped block 20 is attached to the outer peripheral wall of the fixing rod 18. The upper and lower ends of the cross block 6 are provided with second observation grooves 8 for observation.

[0047] In this embodiment, specifically: the illumination component includes a plurality of first fixing blocks 13 fixed to the outer peripheral wall of the rotating rod 12 and an LED lamp 14 fixed to one end of the first fixing blocks 13 near the center of the colorimeter box 1.

[0048] In this embodiment, specifically: the camera assembly includes a plurality of second fixing blocks 15 fixed to the outer peripheral wall of the rotating rod 12 and a camera 16 fixed to one end of the second fixing blocks 15 near the center of the colorimeter box 1. The second fixing blocks 15 and the first fixing blocks 13 are arranged alternately.

[0049] In this embodiment, specifically: the first driving mechanism includes a third motor 27 fixed to one side of the inner wall of the colorimeter box 1 and a first gear 28 fixed to the output shaft of the third motor 27, wherein the first gear 28 and one of the toothed rings 29 mesh with each other.

[0050] In this embodiment, specifically: the second drive mechanism includes a miniature electric cylinder 35 fixed to the inner wall of one end of the colorimeter box 1, a movable block 36 fixed to the output shaft of the miniature electric cylinder 35, a fourth motor 37 fixed to the inner wall of the movable block 36, and a second gear 38 fixed to the output shaft of the fourth motor 37. When the movable block 36 moves, the second gear 38 will mesh with another gear ring 29.

[0051] In this embodiment, specifically: the moving mechanism includes a threaded post 33 rotatably mounted on the inner walls of both ends of the colorimeter box 1, an internally threaded cylinder 32 fixedly connected to the inner box 30, and a motor 34 fixedly connected to one end of the colorimeter box 1. The output shaft of the motor 34 passes through the side wall of the colorimeter box 1 and is fixedly connected to one end of the threaded post 33. The outer peripheral wall of the threaded post 33 and the inner wall of the internally threaded cylinder 32 are adapted to each other. The two sides of the inner box 30 are in contact with the two sides of the inner wall of the colorimeter box 1.

[0052] In this embodiment, specifically: the color-changing mechanism includes a first rotating roller 21, a second rotating roller 22, a third rotating roller 23, a fourth rotating roller 24 and a limiting roller 26 rotatably mounted on the inner walls of both sides of the color matching box 1. The outer peripheral walls of the first rotating roller 21, the second rotating roller 22, the third rotating roller 23 and the fourth rotating roller 24 are together fitted with a transparent strip 25. At least one third observation groove 251 is opened through the transparent strip 25. A second motor 241 is fixedly connected to one side of the color matching box 1. The output shaft of the second motor 241 passes through the side wall of the color matching box 1 and is fixedly connected to one end of the fourth rotating roller 24.

[0053] In this embodiment, specifically: the controller 4 integrates a wireless communication module, which is electrically connected to the camera 16 and is used to wirelessly transmit the image data collected by the camera 16 to an external terminal.

[0054] Working principle: Open the cover plate 2, place the soil sample of the root system of the poplar seedling to be tested on the bottom surface of the inner wall of the colorimetric box 1, then close the cover plate 2, and fully insert the cross block 6 of the shielding component along the cross groove 5 on the cover plate 2. At this time, the cross block 6 closes the first observation groove 7. If it is necessary to completely block out external light, the shielding plate 19 can be pulled to completely cover the second observation groove 8. The shielding plate 19 is hung on the fixing rod 18 through the arc block 20 on it to maintain a fixed state, thereby forming a controlled darkroom environment inside the colorimetric box 1.

[0055] The system is started by the controller 4, and the battery 11 supplies power to each electrical component. First, the motor 34 of the moving mechanism is started. The motor 34 drives the threaded column 33 to rotate. Through the threaded engagement with the inner threaded cylinder 32, it drives the inner box 30 and the multiple colorimetric cards 31 carried on it to move horizontally along the bottom surface of the colorimetric box 1 until the target colorimetric card 31 area is in the observation position.

[0056] Next, the third motor 27 of the first drive mechanism is started. The third motor 27 drives the first gear 28, which is fixed to its output shaft, to rotate. The first gear 28 meshes with the gear ring 29 fixed to a rotating rod 12, thereby driving the rotating rod 12 and the lighting and camera components mounted on it to rotate synchronously.

[0057] The lighting component consists of multiple first fixing blocks 13 fixed on the rotating rod 12 and LED lights 14 disposed at its ends. The camera component consists of multiple second fixing blocks 15 fixed on the rotating rod 12 and camera 16 disposed at its ends. The first fixing blocks 13 and the second fixing blocks 15 are arranged alternately to achieve the coordination of lighting and shooting.

[0058] By adjusting the third motor 27 via the controller 4, the LED light 14 and the camera 16 can be adjusted to the optimal illumination and shooting angles. Then, the LED light 14 is turned on to provide a stable light source, and the camera 16 is activated to acquire images.

[0059] To simulate colorimetry under different spectral conditions, the second motor 241 of the color-changing mechanism can be activated. The second motor 241 drives the fourth rotating roller 24 to rotate, which in turn drives the transparent strip 25 sleeved on the first rotating roller 21, the second rotating roller 22, the third rotating roller 23 and the fourth rotating roller 24 to move.

[0060] The transparent strip 25 can be segmented with filter films of different colors. When the light emitted by the LED lamp 14 passes through the different colored segments of the transparent strip 25 in sequence, it can form light with different spectral characteristics, which will respectively illuminate the soil sample and the colorimetric card 31 below.

[0061] The third observation slot 251 opened on the transparent strip 25 can be used for white light observation without filtering. The camera 16 collects images of soil color and corresponding color chart 31 color under different filtering conditions (or when passing through the third observation slot 251) and transmits the data to the controller 4 for processing and comparison.

[0062] If the first drive mechanism fails, the backup second drive mechanism can be activated: the miniature electric cylinder 35 pushes the movable block 36 and its fourth motor 37 and second gear 38 to move towards the gear ring 29 on another rotating rod 12 until the second gear 38 meshes with the gear ring 29. Then, driven by the fourth motor 37, it can realize independent or coordinated control of another set of lighting and imaging components, thereby obtaining more comprehensive comparison data. The entire workflow realizes automation from sample placement, environmental enclosure, light source and shooting angle adjustment, multispectral simulation to image acquisition and comparison, effectively improving the accuracy, repeatability and efficiency of colorimetry.
