Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology and relates to a seeding simulation detection device, specifically a simulation detection device for detecting the seeding frequency and quantity of different types of seeders. Background Technology

[0002] In agricultural production, the sowing process is crucial. During sowing, seeds are dispersed across the field by gravity and inertia, and different types of seeders result in varying seed distribution patterns. Therefore, a device is urgently needed to monitor seed sowing. However, due to the complex farmland environment and numerous interfering factors, direct observation and recording of sowing conditions are difficult. Therefore, it is necessary to simulate sowing to detect the state of the sown seeds, analyze the frequency and quantity of sowing, and then optimize and improve the seeder. Utility Model Content

[0003] This invention addresses the problems of inaccurate and intuitive detection of sowing conditions during sowing and the significant influence of external environmental factors. It proposes a seed drop simulation detection device that uses a seeder and conveyor belt to simulate the sowing state in farmland and a detection box to detect the seed drop status, thereby further improving the accuracy of sowing.

[0004] The seed-fall simulation detection device provided in this application adopts the following technical solution:

[0005] A seed-drop simulation and detection device, comprising various types of seeders; characterized in that the device further comprises:

[0006] The lifting platform is used to support the seeder and adjust its height.

[0007] A conveyor belt is placed below the seeder and is used to transport the seeds after they have been dropped by the seeder.

[0008] The detection box, mounted above the conveyor belt, is equipped with lighting and camera components and a turntable camera inside, used to collect the number and frequency of seed drop, as well as to stabilize the light source.

[0009] The control cabinet, connected and fixed to the detection box, is used to control the angle of the lighting and camera components and the turntable camera.

[0010] A storage box, located at the end of the conveyor belt, is used to collect seeds that fall onto the conveyor belt.

[0011] By adopting the above technical solution, the seeder is supported and its lifting height is adjusted by a lifting platform. After the seeder drops the seeds, they are conveyed to the bottom of the detection box via a conveyor belt. The lighting and camera components and the turntable camera in the detection box collect information such as the number and frequency of seeds dropped. The control cabinet controls the angle of the lighting and camera components and the turntable camera, and the storage box collects the seeds that fall from the conveyor belt. This achieves automated and visual detection of the seeder's seed dropping process, improving the efficiency and accuracy of detection, facilitating timely detection and adjustment of seeding problems, and thus improving seeding quality.

[0012] Furthermore, the lifting platform is composed of a counterweight platform, a fixed frame, a movable rod, and a telescopic rod connected together. The counterweight platform is connected and fixed to the fixed frame, and the movable rod is placed inside the fixed frame and moves up and down along the fixed frame under the drive of the telescopic rod.

[0013] By adopting the above technical solution, the counterweight platform increases the stability of the platform, and the telescopic rod drives the movable rod and the seeder to rise and fall. The structure is simple and easy to operate. The height of the seeder can be adjusted stably and accurately to meet the sowing needs and testing requirements at different heights, thus improving the flexibility and applicability of the device.

[0014] Furthermore, a quick-connect structure is provided between the movable rod and the seeder. The connection structure consists of a top plate and a pin. The pin passes through the top plate and is connected and fixed thereto. The top plate is welded and fixed to the movable rod. The tail of the seeder is connected to the pin in a plug-in connection.

[0015] By adopting the above technical solution, the seeder can be quickly installed and disassembled, improving the versatility and operability of the device and saving preparation time and labor costs before testing.

[0016] Furthermore, the detection box is composed of a column, a first crossbar, a second crossbar, and a box panel; the first crossbar is fixedly connected to the middle of the column for the fixed installation of the turntable camera, and the second crossbar is fixedly connected to the upper part of the column for the fixed installation of the lighting and camera components.

[0017] By adopting the above technical solution, a reasonable and stable installation structure is provided for the turntable camera and lighting and imaging components, which facilitates the precise installation, fixation and collaborative operation of various detection devices, improves the stability and reliability of detection, and facilitates the maintenance and replacement of equipment.

[0018] Furthermore, the lighting and camera assembly is composed of a longitudinal support, a transverse support, a lighting fixture, and a camera fixture connected together. The longitudinal support can move back and forth relative to the second crossbar, and the transverse support can move up and down relative to the longitudinal support. The lighting fixture and the camera fixture are both connected and fixed to the transverse support. The light source is held by the lighting fixture, and the camera is held by the camera fixture. Both the light source and the camera are set perpendicular to the conveyor belt.

[0019] By adopting the above technical solution, the position and angle of the light source and camera can be flexibly adjusted to meet the needs of different detection scenarios, ensuring the clarity and stability of the detection images, enhancing the ability to collect information such as the number and frequency of seed fall, and improving the accuracy and reliability of the detection results.

[0020] Furthermore, the turntable camera consists of a rotating platform and an industrial camera; the rotating platform is fixedly mounted on the first crossbar, the industrial camera is rotatably connected to the rotating platform, and the industrial camera is horizontally oriented towards the conveyor belt.

[0021] By adopting the above technical solution, the rotating platform allows the industrial camera to photograph seeds from multiple angles, making up for the shortcomings of fixed-angle shooting, further improving the detection accuracy of information such as the number and frequency of seed fall, and providing more comprehensive data support for sowing quality assessment.

[0022] Furthermore, a display screen is provided on the rear panel of the testing box for observing the situation inside the testing box.

[0023] By adopting the above technical solutions, the display screen allows operators to monitor the testing process in real time and intuitively, making it easier to quickly detect and handle abnormalities, improving the efficiency and convenience of testing, and also facilitating the real-time analysis and recording of testing data.

[0024] In summary, this utility model has at least one of the following beneficial technical effects:

[0025] (1) The overall structure of this utility model is simple. Operators only need to replace the seeder and observe the sowing situation with the help of the display screen, which realizes the ease of operation. The data display is intuitive and easy to record, which makes it easy for operators to quickly grasp the sowing status and make timely decisions.

[0026] (2) By setting up two cameras (the camera in the lighting and imaging component and the turntable camera), the seed sowing situation can be recorded from multiple angles, which effectively makes up for the shortcomings of single-angle shooting, significantly improves the detection accuracy of information such as the number and frequency of seeds, and provides more detailed data support for sowing quality assessment.

[0027] (3) The display screen design at the rear of the detection box of this utility model reduces the number of times the detection cabinet needs to be opened, avoiding interference from external factors with the observation results. The storage box effectively collects fallen seeds, reducing waste. The fixed design of the control cabinet and the detection box enhances the ease of handling, and the device can simulate the sowing environment for indoor use, making it highly practical and in line with the concept of resource conservation.

Detailed Implementation

[0034] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims. Example

[0035] like Figure 1 As shown, the seed-falling simulation detection device consists of a lifting platform 1, a seeder 2, a conveyor belt 3, a detection box 4, a control cabinet 5, and a storage box 6. The lifting platform 1 is used to support the seeder 2 and adjust its lifting height. The conveyor belt 3 is placed below the seeder 2 and is used to transport the seeds after they fall from the seeder 2. The detection box 4 is placed above the conveyor belt 3 and is used to collect the number and frequency of falling seeds, as well as to stabilize the light source. The control cabinet 5 is connected and fixed to the detection box 4 and is used to control the angle of the lighting and camera components 9 and the turntable camera 10. The storage box 6 is located at the end of the conveyor belt 3 and is used to collect the seeds that fall from the conveyor belt 3.

[0036] To ensure the clarity and stability of the detected images, enhance the ability to collect information such as the number and frequency of seed droplets, and improve the accuracy and reliability of the detection results, this embodiment uses an illumination and imaging assembly 9 and a rotating camera 10 inside the detection box. Specifically, as shown... Figure 4-5As shown, the lighting and camera assembly 9 is composed of a longitudinal support 9-1, a transverse support 9-2, a lighting fixture 9-4, and a camera fixture 9-5 connected together. Both the lighting fixture 9-4 and the camera fixture 9-5 are fixedly connected to the transverse support 9-2. The light source is held by the lighting fixture 9-4, and the camera is held by the camera fixture 9-5. Both the light source and the camera are positioned perpendicularly to the conveyor belt 3. In this embodiment, to achieve multi-angle seed photography, compensating for the shortcomings of fixed-angle photography, and further improving the detection accuracy of information such as the number and frequency of fallen seeds, a turntable camera 10 is used. Figure 4 As shown, the turntable camera consists of a rotating platform and an industrial camera; the rotating platform is fixedly mounted on the first crossbar 4-2, and the industrial camera is rotatably connected to the rotating platform, with the industrial camera horizontally facing the conveyor belt 3. Example

[0037] To increase platform stability and allow for stable and precise adjustment of the seeder's height to accommodate different seeding needs and testing requirements, this improves the device's flexibility and applicability. In this embodiment, a lifting platform is used; specifically, as shown... Figure 2 As shown, the lifting platform 1 is composed of a counterweight platform 1-1, a fixed frame 1-2, a movable rod 1-3, and a telescopic rod 1-4. The counterweight platform 1-1 is connected and fixed to the fixed frame 1-2. The movable rod 1-3 is placed inside the fixed frame 1-2 and moves up and down along the fixed frame 1-2 under the drive of the telescopic rod 1-4. In this embodiment, the counterweight platform 1-1 can not only be used for counterweighting to prevent the lifting platform from tipping over, but also for transporting various types of seeders, making operation more convenient.

[0038] To achieve rapid installation and disassembly of the seeder, improve the versatility and operability of the device, and save preparation time and labor costs before testing, this embodiment uses a plug-in connection between the seeder and the lifting platform. Specifically, as shown... Figure 2-3 As shown, a quick-connect structure is provided between the movable rod 1-3 and the seeder 2. The connection structure consists of a top plate 7 and a pin 8. The pin 8 passes through the top plate 7 and is connected and fixed thereto. The top plate 7 is welded and fixed to the movable rod 1-3. The tail of the seeder 2 is connected to the pin 8.

[0039] To facilitate flexible adjustment of the position and angle of the light source and camera to meet the needs of different detection scenarios, ensure the clarity and stability of the detected images, enhance the ability to acquire data on the number and frequency of seed droplets, and improve the accuracy and reliability of the detection results, the components of the lighting and camera assembly 9 in this example can all be moved and adjusted. Specifically, for example... Figure 5As shown, the inner side of the second crossbar 4-2 is provided with a first horizontal groove 4-5, and the outer side of the longitudinal support 9-1 is fixedly provided with a first slider 9-7. Through the sliding connection between the first slider 9-7 and the first groove 4-5, the longitudinal support 9-1 can be adjusted to move back and forth relative to the second crossbar 4-3. The inner side of the longitudinal support 9-1 is provided with a second vertical groove 9-6, and the two ends of the transverse support 9-2 are fixedly provided with second sliders 9-3. Through the sliding connection between the second sliders 9-3 and the second groove 9-6, the transverse support 9-2 can be adjusted to move up and down relative to the longitudinal support 9-1.

[0040] To facilitate real-time and intuitive monitoring of the testing process by operators, enabling rapid detection and handling of anomalies, and improving testing efficiency and convenience, this embodiment achieves this through a display screen mounted on the testing box. Specifically, as shown... Figure 4 As shown, the display screen 11 is located on the box panel 4-4 behind the detection box 4.

[0041] like Figure 1-5As shown, the working method of the seed-drop simulation detection device is as follows: For adaptability testing of different seeder types, different types of seeders (such as wheat seeders, corn seeders, etc.) are selected, and their tails are aligned with the pins on the movable rod and inserted for quick installation. The height of the movable rod is adjusted by controlling the telescopic rod to adapt to the seed-dropping height requirements of different seeders. Simulated sowing and seed transport are performed by starting the seeder to simulate farmland sowing conditions, with seeds falling onto the conveyor belt under gravity. The conveyor belt smoothly transports the fallen seeds to the bottom of the detection box, ensuring uniform seed distribution for subsequent testing. Seed-dropping status detection is performed, with the lighting and camera components and the turntable camera working in tandem within the detection box. The lighting fixture fixes the light source to ensure uniform illumination in the detection area; the camera fixture fixes the camera, and the light source and camera adjust their positions and angles according to preset parameters, vertically facing the conveyor belt to capture seed images, ensuring image clarity. The turntable camera achieves multi-angle shooting through a rotating platform, capturing comprehensive seed information and improving detection accuracy. The rotating platform of the turntable camera drives the industrial camera to capture seeds on the conveyor belt from multiple angles, recording the distribution, quantity, and frequency of the seeds. Data monitoring and seed collection: A display screen at the rear of the testing box shows the real-time testing results, allowing operators to visually monitor seed distribution. The screen allows for real-time observation of seed distribution, and any abnormalities (such as seed accumulation or uneven distribution) can be immediately adjusted to adjust the seeder or conveyor belt parameters. A storage box at the end of the conveyor belt collects the tested seeds, reducing waste. Data processing and seeder optimization: The control system within the control cabinet analyzes the collected image data, calculates seed distribution frequency and quantity, and generates a testing report. Based on the testing results, seeder parameters or structure are adjusted to optimize seeding performance. This system enables precise detection of different types of seeders and varying seed distribution conditions, providing strong support for seeder optimization.
