Description

Technical Field

[0001] This utility model belongs to the field of corn research, and specifically relates to a corn cob photography device for intelligent corn kernel counting. Background Technology

[0002] Kernel counting is a crucial step in maize research, primarily involving the accurate measurement and statistical analysis of the number of kernels. This process has wide applications in agriculture, plant breeding, and food science. By counting kernels, yields of specific varieties or under specific growing conditions can be assessed, helping farmers and researchers understand the impact of different factors on yield. Furthermore, in breeding research, kernel count can serve as an indicator for selective breeding, helping researchers evaluate the performance of different genotypes. Kernel counting can also aid researchers in analyzing maize quality characteristics such as kernel weight and plumpness.

[0003] In practical applications, existing intelligent corn kernel counting devices, when using visual technology for counting, mostly focus on counting and detecting the kernels that have been peeled off, but lack the ability to directly count the corn kernels on the cob. Since they can only count the peeled kernels and cannot detect the kernels on the cob, the actual number of kernels may be missed. At the same time, counting only the peeled kernels may lead to biased data that cannot reflect the overall condition of the corn cob. Therefore, a corn cob photography device for intelligent corn kernel counting is proposed to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a corn cob photography device for intelligent corn kernel counting, including a corn cob photography device body;

[0006] The main body of the corn cob photography device includes a horizontally placed base, a vertical frame is vertically installed on the upper surface of the base, and a sliding seat is slidably arranged on the outside of the vertical frame;

[0007] A corn kernel counting platform is fixedly installed on one side of the sliding seat, and a corn cob clamping assembly is mounted on the upper surface of the corn kernel counting platform.

[0008] The corn cob clamping assembly includes a clamping seat disposed on the upper surface of the corn kernel counting platform. Two linear guide rails are arranged parallel to each other on the upper surface of the clamping seat, and two guide rail sliders are slidably disposed on the outside of the two linear guide rails.

[0009] The two guide rail sliders are symmetrically arranged around the center point of the clamping seat, and the upper surfaces of the two guide rail sliders are each supported by a number of support rods, and the upper surfaces of the support rods are jointly supported by a clamping block.

[0010] Each of the two clamping blocks is equipped with a bearing ring, and a limit shaft tube is rotatably assembled inside the bearing ring.

[0011] As a further improvement of this utility model, the two limiting shaft tubes are symmetrically arranged along the center point of the clamping seat and both of their opposite sides are provided with internal hexagonal slots. A corn cob string is inserted between the two limiting shaft tubes. Both ends of the corn cob string are integrally provided with hexagonal screws that are adapted to the internal hexagonal slots.

[0012] As a further improvement of this utility model, two support plates are fixedly provided on the side of one of the clamping blocks, and a stepper motor is assembled between the two support plates. The output end of the stepper motor passes through the clamping block and is connected to one side of the limiting shaft tube.

[0013] As a further improvement of this utility model, the corn cob clamping assembly also includes a positive and negative threaded screw rotating within the clamping seat, and two screw sliders are externally engaged with the positive and negative threaded screw; the two screw sliders are respectively engaged with one of the threads of the positive and negative threaded screw, and the two screw sliders are respectively connected to one of the guide rail sliders.

[0014] As a further improvement of this utility model, a reciprocating motor is installed on the side of the clamping seat, and the output end of the reciprocating motor passes through the clamping seat and is connected to one end of the forward and reverse threaded rod.

[0015] As a further improvement of this utility model, a crossbeam is vertically arranged at the top of the vertical frame, and a visual camera body is installed on the lower end face of the crossbeam. The visual camera body is mounted vertically above the corn cob clamping assembly. A tightening bolt is threadedly connected to the external thread of the sliding seat, and one end of the tightening bolt passes through the sliding seat and abuts against the vertical frame.

[0016] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0017] This utility model discloses a corn cob photographing device for intelligent corn kernel counting. In practical use, through the mutual linkage between the corn cob photographing device body and the corn cob clamping component, when the corn cob is restrained on the corn cob clamping component, the stepper motor in the corn cob clamping component, in conjunction with the corn cob string rod, can control the rotation of the corn cob. After the corn cob string rod rotates a certain angle, the visual imaging camera body can take a picture of the corn cob. Thus, after the corn cob has completely rotated one revolution, the visual imaging camera body can capture different sides of each corn kernel on the corn cob, reducing omissions caused by angle issues, thereby achieving accurate imaging of the corn kernels on the cylindrical corn cob for subsequent counting processing.

[0018] This utility model discloses a corn cob photographing device for intelligent corn kernel counting. In practical use, through the mutual movement and cooperation of multiple structures within the corn cob clamping assembly, two relatively sliding clamping blocks can work with a limiting shaft tube to clamp corn cobs of different lengths. The corn cob clamping assembly of this application can adapt to corn cobs of different lengths and diameters, allowing the visual imaging camera to handle corn cob samples of various specifications during photographing and counting, increasing the flexibility and adaptability of the experiment. At the same time, through the corn cob string rod and the limiting at both ends of the corn cob string rod, the corn cob clamping assembly can be more stable when restricting the corn cobs, reducing shaking and displacement during shooting or processing, and improving the safety of the experiment.

[0019] This utility model discloses a corn cob photographing device for intelligent corn kernel counting. In actual use, through the sliding adjustment between the sliding seat and the tightening bolt, the corn kernel counting platform can freely adjust the vertical height of the corn cob clamping component. Thus, when the corn cob clamping component restricts the corn kernels, the visual imaging camera can take pictures of the corn cob at different heights, making it more in line with the shooting requirements of the visual imaging camera, thereby improving image quality and increasing the accuracy of subsequent corn kernel counting on the corn cob.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] Depend on Figure 1-4 Provided is a corn cob photographing device for intelligent corn kernel counting, including a corn cob photographing device body 10;

[0028] The main body 10 of the corn cob photography device includes a horizontally placed base 11, a vertical frame 12 is vertically installed on the upper surface of the base 11, and a sliding seat 2 is slidably arranged on the outside of the vertical frame 12.

[0029] A corn kernel counting platform 3 is fixedly installed on one side of the sliding seat 2, and a corn cob clamping assembly 4 is mounted on the upper surface of the corn kernel counting platform 3.

[0030] The corn cob clamping assembly 4 includes a clamping seat 41 disposed on the upper end face of the corn kernel counting platform 3. Two linear guide rails 42 are arranged parallel to each other on the upper end face of the clamping seat 41 in the transverse direction. Two guide rail sliders 43 are slidably disposed on the outside of the two linear guide rails 42.

[0031] Two guide rail sliders 43 are symmetrically arranged along the center point of the clamping seat 41, and several support rods 44 are mounted on the upper surface of both guide rail sliders 43. The upper surface of the several support rods 44 together bears the clamping block 45.

[0032] Each of the two clamping blocks 45 is fitted with a bearing ring 46, and a limit tube 47 is rotatably fitted inside the bearing ring 46.

[0033] In this embodiment, in actual use, through the mutual linkage between the corn cob photography device body 10 and the corn cob clamping component 4, when the corn cob is restricted on the corn cob clamping component 4, the stepper motor 410 in the corn cob clamping component 4 can cooperate with the corn cob stringing rod 414 to control the rotation of the corn cob. When the corn cob stringing rod 414 rotates a certain angle, the visual photography camera body 14 can take a picture of the corn cob. Thus, when the corn cob has rotated a full circle, the visual photography camera body 14 can capture the different surfaces of each corn kernel on the corn cob, reducing omissions caused by angle issues, thereby achieving accurate imaging of the corn kernels on the cylindrical corn cob for subsequent counting processing.

[0034] Furthermore, through the mutual movement and cooperation of multiple structures within the corn cob clamping assembly 4, the two relatively sliding clamping blocks 45 can cooperate with the limiting shaft tube 47 to clamp corn cobs of different lengths. The corn cob clamping assembly 4 of this application can adapt to corn cobs of different lengths and diameters, allowing the visual imaging camera body 14 to process corn cob samples of various specifications during image capture and counting, increasing the flexibility and adaptability of the experiment. At the same time, through the corn cob string rod 414 for threading the corn cobs and the internal hexagonal slot 48 for limiting both ends of the corn cob string rod 414, the corn cob clamping assembly 4 can be more stable when restricting the corn cobs, reducing shaking and displacement during the shooting or processing process, and improving the safety of the experiment.

[0035] Furthermore, in order to improve the image quality of the visual camera body 14, in a preferred embodiment, the corn kernel counting platform 3 is provided with a pure black matte back panel, which can make the corn photos taken have high contrast.

[0036] Specifically, refer to Figure 1-4 Two limiting shaft tubes 47 are symmetrically arranged along the center point of the clamping seat 41, and each of their opposite sides is provided with an internal hexagonal slot 48. A corn cob stringing rod 414 is inserted between the two limiting shaft tubes 47. Both ends of the corn cob stringing rod 414 are integrally provided with hexagonal screws that are compatible with the internal hexagonal slots 48.

[0037] In this embodiment, in actual use, when the two limiting shaft tubes 47 gradually approach each other and move to the end of the corn cob string rod 414, the user can pass the corn cob through the outside of the corn cob string rod 414 and place the corn cob string rod 414 horizontally between the two limiting shaft tubes 47. This utilizes the engagement and limiting of the internal hexagonal slot 48 and the corn cob string rod 414 to achieve the horizontal placement of the corn cob string rod 414 between the two limiting shaft tubes 47.

[0038] Furthermore, by limiting the corn cob string rod 414 through the internal hexagonal slot 48, when the limiting shaft tube 47 rotates, the corn cob string rod 414 can avoid free rotation with the bearing ring 46, thereby stably driving the corn cob to rotate.

[0039] Specifically, refer to Figure 1-4 Two support plates 49 are fixedly installed on the side of one of the clamping blocks 45. A stepper motor 410 is installed between the two support plates 49. The output end of the stepper motor 410 passes through the clamping block 45 and is connected to one side of the limiting shaft tube 47.

[0040] In this embodiment, the user connects the stepper motor 410 to a power supply and a controller, so that it can drive one of the limiting shaft tubes 47 to rotate. Due to the limitation of the hexagonal slot 48 and the end of the corn cob string rod 414, the corn cob string rod 414 can drive the corn cob as a whole to rotate.

[0041] Furthermore, the power connection method of the stepper motor 410 is existing technology, and the control circuit between it and the visual camera body 14 can be implemented by simple programming by those skilled in the art. It is common knowledge in the art, and it is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0042] Specifically, refer to Figure 2-3 The corn cob clamping assembly 4 also includes a positive and negative threaded screw 411 that rotates within the clamping seat 41. Two screw sliders 412 are externally engaged with the positive and negative threaded screw 411. The two screw sliders 412 are respectively engaged with one of the threads of the positive and negative threaded screw 411, and the two screw sliders 412 are respectively connected to one of the guide rail sliders 43.

[0043] In this embodiment, the forward and reverse threaded screw 411 can limit the screw slider 412. When the forward and reverse threaded screw 411 rotates, it is limited by the two linear guide rails 42, so that the screw slider 412 meshing with the outside of the forward and reverse threaded screw 411 can drive the guide slider 43 to move linearly along the stroke range of the forward and reverse threaded screw 411.

[0044] Furthermore, the forward and reverse threads of the screw 411 simultaneously limit the movement of the two guide rail sliders 43, allowing them to move in opposite directions or separate in opposite directions.

[0045] Specifically, refer to Figure 3-4 A reciprocating motor 413 is mounted on the side of the clamping seat 41. The output end of the reciprocating motor 413 passes through the clamping seat 41 and is connected to one end of the forward and reverse threaded rod 411.

[0046] In this embodiment, the reciprocating motor 413 can drive the forward and reverse threaded screw 411 to rotate.

[0047] Furthermore, the power connection method of the forward and reverse threaded rod 411 is existing technology, and its control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the field. It is only used and not modified. Therefore, the control method and circuit connection will not be described in detail.

[0048] Specifically, refer to Figure 1-2 A crossbeam 13 is vertically installed at the top of the vertical frame 12, and a visual camera body 14 is installed on the lower end face of the crossbeam 13. The visual camera body 14 is mounted vertically above the corn cob clamping assembly 4. A tightening bolt 21 is threadedly connected to the external sliding seat 2. One end of the tightening bolt 21 passes through the sliding seat 2 and abuts against the vertical frame 12.

[0049] In this embodiment, during use, the user can link and control the stepper motor 410 with the visual imaging camera body 14. By sending a rotation control signal to the stepper motor 410, the stepper motor 410 can drive the corn cob string 414 and the corn cob to rotate. At the same time, when the corn cob rotates a certain angle, the visual imaging camera body 14 can take a picture. Thus, when the corn cob string 414 has completed one full rotation, the visual imaging camera body 14 can take pictures of the corn cob from multiple perspectives, so that the originally cylindrical corn cob can be captured as multiple planar images. For example, in a specific preferred embodiment, when the stepper motor 410 drives the rotation 4 times, it means that the corn cob will complete one full rotation after 4 rotations. The angle of one rotation is 90 degrees. At this time, the visual imaging camera body 14 can take a complete picture of the corn cob after taking four pictures.

[0050] It should be noted that the main purpose of the above rotation and photography operations is to capture multiple flat images of the cylindrical corn cob, which are then processed into a single photograph for further visual inspection to count the corn kernels.

[0051] Furthermore, through the sliding adjustment between the sliding seat 2 and the tightening bolt 21, the corn kernel counting platform 3 can freely adjust the vertical height of the corn cob clamping assembly 4. Thus, when the corn cob clamping assembly 4 restricts the corn kernels, the visual imaging camera 14 can take pictures of the corn cobs at different heights, making it more suitable for the shooting requirements of the visual imaging camera 14, thereby improving image quality and increasing the accuracy of subsequent counting of corn kernels on the corn cob.

[0052] This utility model relates to a corn cob photographing device for intelligent corn kernel counting:

[0053] Step 1: In actual use, when the user needs to count the corn kernels on a corn cob, the corn cob stringing rod 414 is passed through the corn cob to be counted. The stringing rod 414 is then horizontally placed between two limiting shaft tubes 47. The user then connects a power source to the reciprocating motor 413, causing the reciprocating motor 413 to drive the forward and reverse threaded screw 411 to rotate. When the forward and reverse threaded screw 411 rotates, it is limited by the two linear guide rails 42 on the guide rail slider 43, causing the screw slider 411 to engage with the outside of the forward and reverse threaded screw 411. 12 can drive the guide rail slider 43 to move linearly along the stroke range of the positive and negative threaded rod 411, while being limited by the positive and negative threads of the positive and negative threaded rod 411, so that the two guide rail sliders 43 can move in opposite directions to clamp or move in opposite directions to separate. The user controls the number of rotations and direction of the positive and negative threaded rod 411, so that the two limiting shaft tubes 47 gradually approach each other until the two limiting shaft tubes 47 move to the end of the corn cob string rod 414, thereby using the internal hexagonal slot 48 and the corn cob string rod 414 to achieve horizontal placement of the corn cob string rod 414 between the two limiting shaft tubes 47.

[0054] Step 2: When the corn cob string 414 with the corn cob inserted is limited between the two limiting shafts 47, the user then connects the power supply and controller to the stepper motor 410, so that it can drive one of the limiting shafts 47 to rotate. Due to the limitation of the hexagonal socket 48 and the end of the corn cob string 414, the corn cob string 414 can drive the corn cob to rotate as a whole. At this time, the user links the stepper motor 410 with the visual imaging camera body 14, and controls the rotation angle of the corn cob string 414 through the stepper motor 410. When the corn cob string 414 rotates once, the visual imaging camera body 14 can take a picture of the corn cob. When the corn cob string 414 has rotated a full circle, the visual imaging camera body 14 can take pictures of the corn cob from multiple perspectives, so that the originally cylindrical corn cob is captured as multiple flat pictures, which are convenient for post-processing into a whole picture and counting.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
