Description

Technical Field

[0001] This utility model relates to the field of tobacco machinery technology, and in particular to a tobacco plant image acquisition device. Background Technology

[0002] In the agricultural sector, tobacco is an important economic crop, and accurate monitoring of its planting and growth status is crucial for improving tobacco yield and quality. The growth status of tobacco plants is affected by a variety of factors, and changes in these factors are directly reflected in the appearance characteristics of tobacco plants, such as shape and color. Therefore, it is necessary to collect image information in a timely manner during the growth process of tobacco plants to ensure the quality of the finished tobacco product.

[0003] Existing tobacco plant image acquisition devices consist of a trolley and an image acquisition mechanism. The image acquisition mechanism is fixed to the trolley, which moves to acquire images of different tobacco plants to determine whether they meet production standards. If not, targeted measures can be taken in a timely manner, such as rational fertilization, precision irrigation, and pest and disease control. Furthermore, it can provide data support for intelligent management of tobacco cultivation, thereby achieving the goal of cost reduction and efficiency improvement. However, in actual acquisition, existing tobacco plant image acquisition devices are easily affected by sunlight reflection during image capture, resulting in unclear images. This leads to subsequent systems being unable to provide accurate judgments based on the image content, and may even result in misjudgments.

[0004] Therefore, there is an urgent need for a tobacco plant image acquisition device to solve the above-mentioned technical problems. Utility Model Content

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0039] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] like Figures 1 to 9 As shown, this utility model provides a tobacco plant image acquisition device, including a base 1, a flipping mechanism 2, a shielding mechanism 3, and an image acquisition mechanism. The flipping mechanism 2 includes a flipping element 21 and a first driving component 22. The flipping element 21 is rotatably connected to the end of the base 1. The first driving component 22 is disposed on the base 1 and is used to drive the flipping element 21 to rotate, thereby flipping the flipping element 21 between a retracted position and a working position. The shielding mechanism 3 includes a storage component 31 and a curtain 32. The storage component 31 is disposed on the flipping element 21, and the curtain 32 is disposed on the storage component 31. The storage component 31 is used to unfold or close the curtain 32. The image acquisition mechanism is used to acquire images of tobacco plants. When the flipping element 21 is in the working position, the image acquisition mechanism is located on the side of the shielding mechanism 3 away from the flipping element 21.

[0043] When acquiring images of tobacco plants, the screen 32 is unfolded using the storage component 31, and the blocking mechanism 3 is flipped using the flipping mechanism 2, positioning the blocking mechanism 3 in front of the tobacco plants. The image acquisition mechanism then captures the images of the tobacco plants. The screen 32 effectively avoids interference from sunlight reflections on the tobacco plant image acquisition, resulting in clearer images. This provides a high-quality data foundation for subsequent accurate analysis of the tobacco plants' growth stage and health status, reducing misjudgments caused by unclear images and improving the accuracy of the analysis results. The flipping mechanism 2 reduces the space occupied by the device, facilitating storage and transportation, and improving its practicality and convenience. Closing the screen 32 using the storage component 31 prevents external dirt and dust from adhering to it, protecting the screen 32 and maintaining its reflective effect, thus improving the reliability of the device.

[0044] Optionally, the base 1 has a handle 12 at one end and a roller 13 at the bottom. By providing the roller 13 and the handle 12, the device can be easily moved to the location of the tobacco plant.

[0045] Optionally, such as Figure 3 As shown, the base 1 includes a U-shaped rod 14 and a connecting rod 15. The connecting rod 15 is located at the opening of the U-shaped rod 14, and both ends of the connecting rod 15 are connected to the U-shaped rod 14 via rotating shafts 16. The bottom of the flipping component 21 is provided with two arc-shaped plates 210, which are rotatably connected to two rotating shafts 16 respectively. With this configuration, the space occupied by the device is further reduced when the flipping component 21 is in the retracted position. Furthermore, the U-shaped rod 14 includes a horizontal rod and two vertical rods located at both ends of the horizontal rod, with a handle 12 mounted on one of the vertical rods.

[0046] Optionally, the first drive assembly 22 includes a first drive member 221, a first lead screw 222, a first slider 223, and a first connector 224. The first drive member 221 is fixed to the base 1. Specifically, the first drive member 221 is a motor and is fixed to the horizontal bar of the U-shaped rod 14. The output end of the first drive member 221 is fixedly connected to the first lead screw 222 and is used to drive the first lead screw 222 to rotate. The first slider 223 is threadedly connected to the first lead screw 222. The first end of the first connector 224 is rotatably connected to the first slider 223, and the second end of the first connector 224 is rotatably connected to the flipper 21. When not in operation, the flipper 21 is in the retracted position. When in operation, by activating the first drive member 221, the first lead screw 222 is rotated, causing the first slider 223 to move away from the first drive member 221 on the first lead screw 222. Subsequently, the first connector 224 drives the flipper 21 to flip, causing the flipper 21 to flip to the working position. With the above settings, the first drive component 22 can achieve precise control over the flipping position of the flipping component 21, ensuring that the screen 32 can more effectively avoid the influence of sunlight on the images captured by the image acquisition mechanism.

[0047] To ensure the stability of the structure during the flipping process, optionally, in this embodiment, the first drive assembly 22 further includes a first guide 225, a second slider 226, and a second connector 227. The first guide 225 is fixed to the base 1 and is arranged parallel to the first lead screw 222. The second slider 226 is slidably connected to the first guide 225. The first end of the second connector 227 is rotatably connected to the second slider 226, and the second end of the second connector 227 is rotatably connected to the flipping component 21.

[0048] Optionally, such as Figure 4 As shown, the storage component 31 is connected to a slider 33, such as... Figure 5 As shown, the flipping component 21 is provided with a groove 211, and the storage component 31 is slidably connected to the groove 211 via a slider 33. A first elastic element 34 is provided between the bottom of the slider 33 and the bottom surface of the groove 211. The first elastic element 34 allows the top of the slider 33 to abut against the top surface of the groove 211. One end of the storage component 31 along the sliding direction is provided with an insert 35. After the flipping component 21 is in the working position, the insert 35 can move downward and insert into the soil by sliding the storage component 31 downward along the length direction of the groove 211, further improving the stability of the device during the tobacco image acquisition process and reducing the impact of external wind on the device. By setting the first elastic element 34, the top of the slider 33 abuts against the top surface of the groove 211, realizing the automatic reset of the storage component 31. Optionally, the first elastic element 34 is an alloy spring, and the elastic force of the first elastic element 34 is greater than the overall weight of the shielding mechanism 3.

[0049] Optionally, in this embodiment, the flipping component 21 includes a flipping body 212, which includes a first U-shaped frame 2122 and a second U-shaped frame 2123. The first U-shaped frame 2122 is rotatably connected to the end of the base 1, the storage component 31 is disposed on the first U-shaped frame 2122, and the second U-shaped frame 2123 is disposed on the side of the first U-shaped frame 2122 away from the storage component 31. Both ends of the second U-shaped frame 2123 can be detachably connected to the first U-shaped frame 2122. This configuration is simple and allows the flipping body 212 to flip 90 degrees relative to the horizontal plane.

[0050] Optionally, in this embodiment, as Figure 1 As shown, the flipping component 21 includes a flipping body 212 and a first abutting block 213, as... Figure 4 As shown, the storage component 31 is connected to the second abutment block 36, and the flipping body 212 is provided with a through hole 2121. Specifically, the second U-shaped frame 2123 is provided with a through hole 2121, and the first abutment block 213 slides through the through hole 2121 and can abut against the second abutment block 36. A second elastic member 214 is connected between the first abutment block 213 and the flipping body 212. The second end of the first connecting member 224 is rotatably connected to the first abutment block 213. The base 1 is provided with a limiting member 11 to limit the position of the flipping member 21 so that the flipping member 21 is in the working position. When the flipping member 21 is in the working position, when the first sliding member 223 moves towards the flipping body 212 on the first lead screw 222, the first abutment block 213 abuts against the second abutment block 36, so that the storage component 31 slides downward along the length direction of the slide groove 211 and the insert 35 moves downward. This design results in a compact structure and improves the automation level of the device. The downward movement and insertion of the inserting member 35 into the soil can be achieved by driving the first drive component 22 of the flipping mechanism 2. Since the first abutting block 213 slides through the through hole 2121 of the flipping body 212, connecting the second elastic member 214 between the first abutting block 213 and the flipping body 212 prevents the first abutting block 213 from detaching from the flipping body 212 during the flipping process. Specifically, the second elastic member 214 is an alloy spring, and the elastic force of the second elastic member 214 is greater than the overall weight of the blocking mechanism 3 and the flipping member 21.

[0051] In this embodiment, as Figure 6 As shown, there are two first abutment blocks 213, and two second elastic members 214 are arranged one-to-one with the two first abutment blocks 213. The second end of the first connecting member 224 is rotatably connected to one of the first abutment blocks 213, and the second end of the second connecting member 227 is rotatably connected to the other first abutment block 213. Optionally, in this embodiment, the first abutment block 213 is provided with a first inclined surface 2131, and the second abutment block 36 is provided with a second inclined surface 361. The first inclined surface 2131 and the second inclined surface 361 are arranged opposite to each other and can abut.

[0052] Optionally, in this embodiment, as Figure 7 As shown, the limiting member 11 is an L-shaped plate. When the flipping member 21 is in the working position, the flipping body 212 is at a 90-degree angle to the horizontal plane, and the inner side of the L-shaped plate abuts against the outer side of the flipping body 212. By setting the limiting member 11, the flipping body 212 is limited, allowing the first driving component 22 to drive the first abutting block 213 to slide independently, causing the inserting member 35 to move downward and insert into the soil.

[0053] Optionally, in this embodiment, as Figure 4 , Figure 8 and Figure 9 As shown, the storage component 31 includes a frame 311, a first fixing member 312, a second fixing member 313, and a second driving component 314. The frame 311 is disposed on the flipping member 21, and the first fixing member 312 is disposed on the frame 311. The two ends of the curtain 32 are respectively fixed to the first fixing member 312 and the second fixing member 313. The second driving component 314 can drive the second fixing member 313 to move linearly, causing the curtain 32 to unfold or close. By activating the second driving component 314, the second fixing member 313 is driven to move linearly, thus unfolding the curtain 32.

[0054] Optionally, the second drive assembly 314 includes a second drive member 3141 and a second lead screw 3142. The second drive member 3141 is fixed to the frame 311. Specifically, the second drive member 3141 is a motor. The output end of the second drive member 3141 is fixedly connected to the second lead screw 3142 and is used to drive the second lead screw 3142 to rotate. The second fixing member 313 is threadedly connected to the second lead screw 3142. Through the above configuration, the second drive assembly 314 can achieve precise control over the movement position of the second fixing member 313, ensuring the unfolding effect of the curtain 32. In addition, the second drive assembly 314 also includes a second guide member 3143. The second guide member 3143 is fixed to the frame 311 and is arranged parallel to the second lead screw 3142. The second fixing member 313 is slidably connected to the second guide member 3143. This configuration ensures the stability of the second fixing member 313 during movement.

[0055] Optionally, in this embodiment, the storage assembly 31 further includes a storage cylinder 315 and a spiral spring 316. The storage cylinder 315 is fixed to the frame 311, the first fixing member 312 is rotatably connected inside the storage cylinder 315, one end of the spiral spring 316 is fixedly connected to the top of the first fixing member 312, and the other end of the spiral spring 316 is fixedly connected to the inner wall of the top of the storage cylinder 315. When the screen 32 is not in use, the second driving member 3141 drives the second lead screw 3142 to rotate, causing the second fixing member 313 to move closer to the storage cylinder 315. Combined with the force of the spiral spring 316, the first fixing member 312 rotates along the inner wall of the storage cylinder 315, thereby storing the screen 32 inside the storage cylinder 315. With this configuration, when the screen 32 is not in use, it is protected by the storage cylinder 315, which can prevent external dirt or dust from adhering to the outer wall of the screen 32 and affecting the reflective effect during subsequent use or shooting.

[0056] In this embodiment, as Figure 4 As shown, both the first fixing member 312 and the storage tube 315 have inserts 35 at their bottoms. The first fixing member 312 and the inserts 35 are integrally formed, as are the storage tube 315 and the inserts 35. In other embodiments, the inserts 35 are fixed to the bottom of the frame 311.

[0057] Optionally, in this embodiment, the image acquisition mechanism includes a camera 41, an image acquisition component, a data storage component, a data analysis component, and a display component. The camera 41 is fixed to the storage component 31 via a bracket 42. The image acquisition component is connected to the camera 41, the data storage component is connected to the image acquisition component, the data analysis component is connected to the data storage component, and the display component is connected to the data analysis component. Further, the camera 41 is an RGB camera. When acquiring images, the image acquisition component works with the RGB camera to capture and acquire images of the tobacco plants, and transmits the acquired data to the data storage component. The data storage component has a built-in large-capacity hard drive, which can store the original images and processed data in real time, and provides a database for the data analysis component. Based on the extracted feature data, the data analysis component assesses the growth stage and health status of the tobacco plants, and transmits the conclusions to the display component, which can be a liquid crystal display screen. Optionally, in this embodiment, one end of the bracket 42 is fitted onto the second fixing member 313, and the camera 41 is fixed to the other end of the bracket 42 by bolts.

[0058] Optionally, in this embodiment, the curtain 32 is black, providing a more pronounced anti-reflective effect. Furthermore, the curtain 32 is equipped with a measuring ruler 321 and a color wheel, which facilitates comparison of the tobacco plant's size and color with the measuring ruler 321 and color wheel, resulting in more accurate subsequent judgments.

[0059] The working process of the tobacco plant image acquisition device in this embodiment:

[0060] When it is necessary to collect images of tobacco plants, the staff pushes the handle 12 to move the device to the designated position of the tobacco plant. Then, the second drive component 3141 is activated, which drives the second lead screw 3142 to rotate. The second lead screw 3142 drives the second fixing component 313 to move linearly away from the first fixing component 312, thereby pulling out the curtain 32 stored in the storage tube 315. The curtain 32 drives the first fixing component 312 to rotate, thus realizing the operation of unfolding the curtain 32.

[0061] The operator activates the first drive unit 221, causing it to rotate the first lead screw 222. This causes the first sliding member 223 to move away from the first drive unit 221 along the lead screw 222, thereby causing the flipping member 21 to flip 90 degrees. The flipping member 21 is then unidirectionally limited by the limiting member 11. The first lead screw 222 continues to rotate, causing the first sliding member 223, the first connecting member 224, and the first abutting block 213 to move laterally horizontally. This causes the outer wall of the first abutting block 213 to abut against and press against the outer wall of the second abutting block 36. The pressing force causes the receiving component 31 to slide downwards along the length of the groove 211, inserting the embedding member 35 into the soil. Finally, an image acquisition mechanism captures images of the tobacco plants.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
