Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a mobile real-time monitoring device for farmland information. Background Technology
[0002] In order to facilitate people's understanding of crop growth status and environmental changes in farmland, and to enable artificial regulation and management decisions, it is necessary to monitor farmland crops and the environment. Agricultural production also requires a large amount of real-time environmental information about farmland, such as climate information, soil conditions, and crop growth information. This information directly affects crop growth and serves as the basis for artificial regulation and management decisions.
[0003] Existing robots, such as the one with patent publication number CN211073606U for monitoring farmland environmental information, include a vehicle body, a control device, a power supply, and an environmental information monitoring device mounted on the vehicle body. By installing this monitoring device, comprehensive environmental information monitoring can be conducted. The monitoring device includes fixed components and sliding parts, enabling wider and more accurate monitoring and collection of farmland environmental information. However, in environments with abundant farmland debris, relying solely on the rolling of the wheels is insufficient to clear or push away obstacles. Farmland often contains accumulations of soft debris such as straw fragments and humus. In such situations, the mobile wheels commonly used by these robots are prone to getting stuck in these areas. Because the contact area between the mobile wheels and the ground is relatively small, they cannot obtain sufficient support in soft debris, making it difficult for the robot to move or even stop moving altogether. This seriously affects the continuity and efficiency of the monitoring work. Because the mobile wheels cannot move freely due to the debris, the actual monitoring range of the robot will be greatly limited. The originally designed large-scale monitoring capability cannot be fully utilized, which may result in some farmland areas not being monitored in a timely and effective manner. This leads to incomplete farmland environmental information and cannot provide a comprehensive and accurate basis for agricultural production decisions. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.
[0018] Please see Figure 1-4 This utility model provides a technical solution:
[0019] A mobile farmland information real-time monitoring device includes a mounting trough body 1. A primary support base 11 is fixedly mounted on both sides of one end of the bottom wall of the mounting trough body 1. A second support base 12 is fixedly mounted on both sides of the other end of the bottom wall of the primary support base 11. A moving component 2 is fixedly mounted on the bottom walls of the primary support base 11 and the second support base 12. The moving component 2 includes a servo motor 21, a rotating shaft 22, a drive wheel set 24, a U-shaped mounting bracket 25, and driven wheels 26. The servo motor 21 is fixedly mounted on the bottom wall of the second support base 12, and the rotating shaft 22 is rotatably mounted to the servo motor 21. The drive wheel set... 24 is fixedly installed at both ends of the rotating shaft 22. The U-shaped mounting bracket 25 is bolted to the bottom wall of the first support base 11. The driven wheel 26 is rotatably installed at the bottom end of the U-shaped mounting bracket 25. The bottom wall of the mounting tank body 1 is fixedly installed with a clearing component 3, which includes a scraper 31 and a support inclined plate 32. The scraper 31 is bolted to the front end of the mounting tank body 1. The support inclined plate 32 is fixedly installed on one side of the bottom wall of the first support base 11 and is located in front of the driven wheel 26. The front end of the mounting tank body 1 is fixedly installed with a blowing component 4. The upper surface of the mounting tank body 1 is fixedly installed with a monitoring device 5.
[0020] In this embodiment, the servo motor 21 of the mobile component 2 provides rotational power for the entire mobile component 2. Its precise speed control ensures that the device moves stably at a preset speed, meeting the speed requirements for monitoring information in different areas of farmland. The rotating shaft 22 transmits power, transferring the rotational force generated by the servo motor 21 to the drive wheel set 24, enabling the drive wheel set 24 to rotate and drive the device forward. The drive wheel set 24 is in direct contact with the ground, generating driving force through rotation to propel the device in the farmland. It is a key component for realizing the device's mobility function. The U-shaped mounting bracket 25 is used to install the driven wheel 26. Its U-shaped structure provides stable support and installation space for the driven wheel 26, ensuring that the driven wheel 26 can rotate flexibly and assisting the device in moving smoothly. The driven wheel 26 cooperates with the drive wheel set 24 to increase the contact points between the device and the ground, improving the stability of the device's movement, while also sharing some of the device's weight and reducing the burden on the drive wheel set 24. The scraper 31 of the obstacle clearing component 3 is installed at the front end of the mounting slot shell body 1, allowing it to directly contact the farmland during device movement. Ground debris is scraped away, such as larger stones, clods of earth, and straw, creating a relatively unobstructed path for the device and reducing obstruction to the moving component 2. The support ramp 32 is fixed to one side of the bottom wall of the first support base 11 and located in front of the driven wheel 26. On the one hand, it provides some support and protection for the driven wheel 26, preventing it from being damaged by excessive impact when encountering larger obstacles. On the other hand, its inclined structure can push some smaller debris to the sides as the device moves forward, further assisting in clearing obstacles. The blowing component 4 is installed at the front end of the mounting tank body 1 and can generate airflow to blow away some lightweight debris, such as dust, leaves, and weed debris, preventing these debris from adhering to the device and affecting its normal operation. It also reduces the interference of debris on components such as the monitoring device. The monitoring device 5 is installed on the upper surface of the mounting tank body 1 and is used to collect various information from the farmland in real time, such as soil moisture, temperature, light intensity, and crop growth status, and transmit this information to the subsequent processing system to provide decision-making basis for agricultural production.
[0021] Workflow: Start-up Preparation: The operator places the mobile farmland information real-time monitoring device 5 in a suitable location in the farmland, connects the power supply, and ensures that all components, such as the servo motor 21 and the monitoring device 5, are in normal working condition. The servo motor 21 is started, which drives the rotating shaft 22 to rotate. The rotating shaft 22 then transmits power to the drive wheel group 24, which begins to rotate, pushing the device forward. During the movement of the device, the scraper 31 at the front end first contacts the debris on the farmland ground, scraping away the larger debris. At the same time, the support inclined plate 32 pushes some smaller debris to both sides. The blowing component 4 starts working, generating airflow to blow away light debris, further clearing the path in front of the device. As the device moves, the monitoring device 5, installed on the upper surface of the mounting tank body 1, begins to collect various information about the farmland in real time.
[0022] Beneficial effects: Through the reasonable design of the moving component 2, the active wheel group 24 and the driven wheel 26 work together to enable the device to move stably on complex farmland terrain. The precise control of the servo motor 21 ensures the uniformity and adjustability of the moving speed, which can adapt to different farmland environments and monitoring needs. The combination of the obstacle clearing component 3 and the blowing component 4 can remove farmland debris of different types and sizes, creating favorable conditions for the movement of the device, reducing device failures and downtime caused by debris obstruction, and improving the working efficiency and reliability of the device. The obstacle clearing and blowing functions reduce the interference of debris on the monitoring device 5, ensuring that the monitoring device can accurately and clearly collect farmland information, improving the accuracy and completeness of monitoring data, and providing more reliable decision support for agricultural production. The components have simple structures and are installed using common connection methods such as bolts, which facilitates quick assembly and disassembly in the field, and also facilitates the maintenance and replacement of each component, reducing the cost of use.
[0023] Specifically, the blowing assembly 4 includes a support frame 41, a protective shell 42, a circular mounting base 43, a stepper motor 44, and a fan 45. One end of the support frame 41 is fixedly installed on both sides of the side wall of the mounting slot shell body 1. The protective shell 42 is fixedly installed in the middle of the other end of the support frame 41. The circular mounting base 43 is fixedly installed on the bottom wall of the protective shell 42. The stepper motor 44 is fixedly installed in the middle of the protective shell 42 and the circular mounting base 43. The fan 45 is rotatably installed on the drive end of the stepper motor 44.
[0024] In this embodiment, one end of the support frame 41 is fixedly installed on both sides of the side wall of the mounting housing 1, serving to connect the entire blowing assembly 4 to the main body of the mobile farmland information real-time monitoring device. This ensures that the blowing assembly 4 can be stably installed on the device and will not easily shake or fall off during device movement, thus guaranteeing the stability of the blowing assembly 4 during operation. By reasonably designing the length and angle of the support frame 41, the protective shell 42 is positioned at a suitable position at the front end of the device, allowing the fan 45 to be in the optimal blowing position. This effectively disperses debris in the path in front of the device without damaging the equipment. To prevent interference with the normal operation of other components, such as the moving component 2 and monitoring equipment, the overall spatial layout of the device is optimized. The protective shell 42 is fixedly installed at the middle of the other end of the support frame 41, providing a reliable physical protection barrier for internal components such as the stepper motor 44 and fan 45. In the complex environment of farmland, it can effectively prevent dust, soil, water droplets, small stones and other debris from entering the interior, avoiding these impurities from causing wear, corrosion or blockage to the precision components of the stepper motor 44 and fan 45, thereby extending the service life of the components and reducing the failure rate. The circular mounting base 43 is fixedly installed. Mounted on the bottom wall of the protective housing 42, it provides additional support and fixing points for the stepper motor 44. Together with the protective housing 42, it forms a stable structural frame, firmly fixing the stepper motor 44 inside the protective housing 42. This reduces the displacement of the stepper motor 44 caused by its own vibration or vibration from device movement during operation, ensuring the stable and reliable operation of the stepper motor 44. In turn, this guarantees the normal rotation of the fan 45. When there is a lot of debris in the farmland or when rapid path clearing is required, the speed of the stepper motor 44 can be increased, allowing the fan 45 to generate a stronger airflow and quickly disperse the debris. When there is less debris or when energy saving is required, the speed of stepper motor 44 can be reduced to reduce energy consumption and improve the overall energy utilization efficiency of the device. Fan 45 rotates at high speed under the drive of stepper motor 44, generating a strong airflow. This airflow can blow away light debris on the farmland, such as dust, leaves, weed debris, crop residues, etc., to open up a relatively clean moving path for the device, reduce the entanglement and obstruction of debris on the moving components 2 of the device, as well as the obstruction and interference to the monitoring device, and ensure that the device can carry out real-time monitoring of farmland information smoothly and accurately.
[0025] Specifically, the protective shell 42 is electrically connected to the monitoring device 5. The monitoring device 5 includes a front monitoring module 51 and a bottom monitoring module 52. The front monitoring module 51 is fixedly installed at the front of the entire monitoring device 5, and the bottom monitoring module 52 is fixedly installed on the bottom front wall of the protective shell 42. The bottom monitoring module 52 is signal connected to the stepper motor 44.
[0026] In this embodiment, the protective shell 42 is electrically connected to the monitoring device 5. The overall circuit system of the protective shell 42 can provide stable power support to the monitoring device 5, ensuring that the front monitoring module 51 and the bottom monitoring module 52 continuously obtain the required power during device operation, thereby carrying out normal farmland information monitoring work and avoiding data loss due to power outages. The front monitoring module 51 is fixedly installed at the front of the monitoring device 5, covering a large field of view. It can monitor the overall environmental conditions of the farmland in real time, including macroscopic information such as weather changes, light intensity, and air humidity, providing a basis for agricultural producers to understand the overall environmental conditions of the farmland. It can observe the overall growth of crops in the farmland, such as planting density, growth height, and color changes. By analyzing this information, common problems that occur during crop growth can be detected in a timely manner, such as large-scale outbreaks of pests and diseases, and yellowing of leaves due to nutrient deficiency, so as to take corresponding prevention and control measures. During the movement of the device, the front monitoring module 51 can detect large obstacles on the path ahead in advance, such as large rocks and fallen trees, and transmit relevant information to the device. The control center enables the device to adjust its movement route in a timely manner to avoid collision damage and ensure safe operation. The bottom monitoring module 52 is fixedly installed on the front bottom wall of the protective shell 42, close to the farmland surface. It can monitor the details of crop roots, stem bases, and other parts clearly and at close range, promptly detecting whether crop roots are affected by pests or diseases, whether soil moisture is suitable, and whether weeds are entangled in the roots. This provides detailed data support for precise farmland management. It can also monitor the surface condition of the farmland soil, such as soil color, texture, and the presence of cracks, combined with relevant data. The sensor technology can also acquire important information such as soil temperature and moisture content, helping agricultural producers understand the soil fertility and moisture status, and carry out irrigation and fertilization operations in a reasonable manner. The bottom monitoring module 52 is connected to the stepper motor 44 by signal, and can intelligently control the operation of the stepper motor 44 according to the monitored farmland conditions. For example, when it is detected that there is a lot of light debris accumulated near the crop roots, affecting crop growth or interfering with monitoring data, the bottom monitoring module 52 can send a signal to the stepper motor 44 to start or speed up the rotation of the fan 45, enhance the airflow, and remove debris in time.
[0027] Specifically, the drive wheel assembly 24 includes a drive center wheel 241, a support rod 242, and a metal wheel 243. The drive center wheel 241 is fixedly installed at both ends of the rotating shaft 22. Several sets of support rods 242 are welded to the outer ends of the drive center wheel 241, and the metal wheel 243 is inserted into the middle of the support rod 242.
[0028] In this embodiment, the active center wheel 241 is fixedly installed at both ends of the rotating shaft 22 and serves as the power hub of the entire active wheel assembly 24. The rotating shaft 22 is typically connected to the servo motor 21 of the device. When the power source is started, the rotating shaft 22 drives the active center wheel 241 to rotate, transmitting power to the entire active wheel assembly 24, enabling the device to obtain forward, backward, or turning power. It is a key starting component for the device to achieve its movement function. The active center wheel 241 provides a stable mounting position for the support rod 242. Its robust design and reasonable dimensions can withstand various forces and torques generated during the movement of the device, ensuring that the support rod 242 and its connected metal wheel 243 remain stable during operation and will not deform or be damaged due to uneven force. Several sets of support rods 242 are welded to the outer ends of the active center wheel 241. Their main function is to connect the active center wheel 241 and the metal wheel 243, distributing the power transmitted by the active center wheel 241 evenly to the metal wheel 243. The support rods 242 provide a stable support structure for the metal wheel 243, enabling the metal wheel 243 to maintain the correct position. The placement and angle of the metal wheel 243 ensure good contact with the ground during movement, providing sufficient friction and support. The rationally designed length and angle of the support rod 242 allow the metal wheel 243 to have a certain ground clearance and swing space, enabling the drive wheel assembly 24 to adapt to different undulating and rugged farmland terrains. When the device passes over raised or recessed ground, the metal wheel 243 can swing up and down under the action of the support rod 242 to maintain contact with the ground, ensuring stable movement of the device and adapting to the complex working environment of farmland. This ensures long-term stable operation of the device. The plug-in installation method makes the installation and disassembly of the metal wheel 243 relatively convenient. The drive center wheel 241, support rod 242, and metal wheel 243 work together to form an efficient drive wheel assembly 24. The drive center wheel 241 provides power, the support rod 242 transmits power and enhances structural strength, and the metal wheel 243 achieves contact with the ground and movement. Together, they ensure the stable and reliable movement of the device in the farmland environment, providing the necessary mobility guarantee for the mobile farmland information real-time monitoring device to complete various monitoring tasks.
[0029] Specifically, a bearing seat 23 is fixedly installed on the bottom wall of the second support base 12, and the two ends of the rotating shaft 22 are inserted into the middle of the bearing seat 23.
[0030] In this embodiment, the second support base 12 serves as an important support structure at the bottom of the device. The bearing seat 23 is fixedly installed on its bottom wall, which provides a stable frame foundation for the entire device. The bearing seat 23 is precisely installed at a specific position on the bottom wall of the second support base 12, providing an accurate installation reference for the rotating shaft 22.
