Description

Technical Field

[0001] This invention relates to the field of agricultural monitoring technology, specifically to a soil monitoring component and an agricultural monitoring vehicle. Background Technology

[0002] With the development of agricultural technology, the efficiency of crop planting, management, and harvesting has been greatly improved. Some areas have adopted grid-based standardized farmland structures, enabling large-scale precision operations with a small number of personnel. New farmland uses 5-10 mu (approximately 0.8-0.67 hectares) as basic units, dividing the land into regular digital grids using the BeiDou satellite positioning system. One management method involves embedding soil temperature and humidity sensors, miniature weather stations, and crop growth monitoring instruments within each grid, forming a comprehensive IoT sensing network. Another method is based on self-propelled intelligent soil monitoring components combined with the BeiDou satellite positioning system for inspection and monitoring. The first method offers more comprehensive monitoring and real-time data acquisition, but its setup cost is too high, requiring a large initial investment, and it may miss some areas. The second method can replace or compensate for the shortcomings of the first method in some situations, relying on its intelligent self-propelled characteristics to patrol the entire farmland.

[0003] The prior art disclosed in announcement number CN111665854A is a self-propelled intelligent soil monitoring component, including a self-propelled navigation vehicle. The self-propelled navigation vehicle is equipped with an instrument platform, on which a controller and multiple monitoring sensors for monitoring different information are installed. During the movement of the self-propelled navigation vehicle, the controller adjusts the height of the instrument platform, and the various monitoring sensors collect various farmland information and control the soil sensors to collect soil information, thereby realizing the flexibility of agricultural monitoring and improving the efficiency of agricultural monitoring data acquisition.

[0004] However, the existing soil monitoring components still have shortcomings. For example, the probe at the bottom of the soil sensor installed on the self-propelled navigation vehicle is always perpendicular to the ground and cannot be tilted and stored when not in use. It is also easily damaged by bumps on the ground when the self-propelled navigation vehicle is moving. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a soil monitoring component and an agricultural monitoring vehicle. This invention solves the technical problem that in the prior art, the detection rod at the bottom of the soil sensor of the self-propelled navigation vehicle is always in a state perpendicular to the ground, and cannot be tilted and stored when not in use. It is also easily damaged by bumps on the ground when the self-propelled navigation vehicle is moving.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a soil monitoring component, comprising: A fixed bracket has a mounting surface and an arc surface, wherein the mounting surface and the arc surface are spaced apart to form an inclined receiving space; and A sensor assembly includes a housing, a hinge plate, and a soil sensor. The hinge plate is disposed on the mounting surface and rotatably connected to the housing. The soil sensor is slidably connected to the housing, and the sliding direction is set at an angle to the mounting surface. When the soil sensor slides toward the arc surface, it can press against the arc surface, so that the arc surface applies a torsional force to the sensor assembly, driving the soil sensor to rotate and be located in the receiving space.

[0007] In some embodiments, the sensor assembly further includes a connecting plate and a hinge, the connecting plate being connected to the housing and rotatably connected to the hinge plate via the hinge.

[0008] In some embodiments, the hinge includes a rod and two bent portions at both ends of the rod, both bent portions being connected to the hinge plate, and the rod being connected to the connecting plate.

[0009] In some embodiments, the fixed bracket has a hollow portion and an arc-shaped strip. The side of the arc-shaped strip facing away from the hollow portion has the arc surface. When the arc surface is pressed by the soil sensor, it can drive the arc-shaped strip to undergo elastic deformation.

[0010] In some embodiments, the fixed bracket has a limiting groove, which drives the housing to engage with the limiting groove when the soil sensor slides away from the arc surface.

[0011] In some embodiments, the soil monitoring assembly further includes a drive mechanism disposed in the housing, the drive mechanism being connected to the soil sensor and used to drive the soil sensor to move up and down.

[0012] In some embodiments, the drive mechanism includes a servo motor, a first gear, and a second gear that mesh sequentially. The second gear is threaded onto the soil sensor. The servo motor can drive the second gear to rotate through the first gear, so that the second gear drives the soil sensor to rise and fall through the threads.

[0013] In some embodiments, the soil sensor has a groove, and the housing has a protrusion that slides and engages with the groove to restrict the rotation of the soil sensor.

[0014] Secondly, the present invention also provides an agricultural monitoring vehicle, including a vehicle body and the aforementioned soil monitoring components, wherein the fixed bracket is disposed on the vehicle body.

[0015] In some embodiments, the monitoring vehicle further includes a camera mounted on the vehicle body.

[0016] Compared with existing technologies, the soil monitoring component provided by this invention has a fixed bracket that can be installed on an agricultural monitoring vehicle. When the agricultural monitoring vehicle travels in farmland, the soil sensor can be used to monitor the soil. When monitoring is needed, the soil sensor can be controlled to slide down relative to the outer shell to insert into the soil. When monitoring is not needed, the soil sensor can be controlled to slide up, with the top of the soil sensor pressing against the arc surface of the fixed bracket. Combined with the soil sensor's own weight and the force at the hinge plate's rotating connection, the arc surface can apply a torsional force to the soil sensor, driving it to rotate towards the receiving space, so that it is located in the receiving space and in an inclined storage state. At this time, the bottom of the soil sensor is less likely to touch obstacles while the agricultural monitoring vehicle is traveling in the farmland, effectively protecting the soil sensor.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] To address the technical problem in existing soil monitoring components where the probe at the bottom of the soil sensor is always perpendicular to the ground, making it impossible to tilt and store it when not in use, and making it susceptible to damage from impacts by protrusions on the ground while the self-propelled navigation vehicle is moving, this invention provides a soil monitoring component that allows the soil sensor to be stored away when not in use, thus protecting the soil sensor.

[0020] It should be noted that the soil monitoring component described in this invention is used in, but not limited to, agricultural monitoring vehicles. For ease of explanation, this invention will only use the application of the soil monitoring component in an agricultural monitoring vehicle as an example. The principle of the soil monitoring component applied to other types of equipment is essentially the same as that applied to an agricultural monitoring vehicle, and will not be described in detail here.

[0021] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a soil monitoring component in one embodiment of the present invention. The soil monitoring component includes a fixed bracket 1 and a sensor component 2. The fixed bracket 1 has a mounting surface 11 and an arc surface 12, and the mounting surface 11 and the arc surface 12 are spaced apart to form an inclined receiving space 13.

[0022] The sensor assembly 2 includes a housing 21, a hinge plate 22, and a soil sensor 23. The hinge plate 22 is disposed on the mounting surface 11 and rotatably connected to the housing 21. The soil sensor 23 is slidably connected to the housing 21 and the sliding direction is set at an angle to the mounting surface 11. When the soil sensor 23 slides toward the arc surface 12, it can press against the arc surface 12 so that the arc surface 12 applies a torsional force to the sensor assembly 2, causing the soil sensor 23 to rotate and be located in the receiving space 13.

[0023] In this embodiment, the fixed bracket 1 includes a first bracket 14, a second bracket 15, and a connecting bracket 16. The two ends of the connecting bracket 16 are respectively connected to the first bracket 14 and the second bracket 15. The part of the first bracket 14 facing the second bracket 15 has an arc surface 12. The part of the second bracket 15 facing the first bracket 14 has a mounting surface 11. The mounting surface 11 and the arc surface 12 are spaced apart to form a receiving space 13. The receiving space 13 is used to store the soil sensor 23 when it is not in use. The receiving space 13 is inclined, so the soil sensor 23 is also in an inclined state when it is located in the receiving space. It is inclined relative to the ground. Therefore, when the soil sensor 23 is in the stored state, it is not only away from the ground, but also in an inclined state. Compared with the existing soil sensor 23 which is in a vertical state, the soil sensor 23 in the present application which is in an inclined state can reduce the risk of touching obstacles and can protect the soil sensor 23.

[0024] In one embodiment, please refer to Figure 1 and Figure 2The fixed bracket 1 has a hollow portion 17 and an arc-shaped strip 171. The side of the arc-shaped strip 171 facing away from the hollow portion 17 has the aforementioned arc surface 12. When the arc surface 12 is pressed by the soil sensor 23, it can drive the arc-shaped strip 171 to undergo elastic deformation. In this embodiment, the first bracket 14 is hollow and has a hollow portion 17. The first bracket 14 can be made of elastic metal. When the top of the soil sensor 23 presses against the arc surface 12, it can drive the arc-shaped strip 171 to undergo a small amount of elastic deformation, thereby applying a large torsional force to the soil sensor 23. During the upward movement of the top of the soil sensor 23, it can rotate more quickly into the receiving space 13. In addition, the first bracket 14 has a screw hole 141 that passes through and connects to the hollow portion 17 for screws to pass through, so that the screws are threadedly connected to the monitoring vehicle, and the soil monitoring components are installed on the monitoring vehicle.

[0025] The second bracket 15 includes a first segment 151, a second segment 152, and a third segment 153 connected in sequence. The first segment 151 and the second segment 152 are arranged perpendicularly, and the third segment 153 is arranged at an angle to the second segment 152. The side of the third segment 153 facing away from the second segment 152 has the aforementioned mounting surface 11. In this embodiment, the second bracket 15 does not have any unnecessary structures, and its structure is simple and ingenious, providing reasonable support for the outer casing 21.

[0026] In one embodiment, please refer to Figure 1 and Figure 2 The fixed bracket 1 has a limiting groove 18, and when the soil sensor 23 slides away from the arc surface 12, it can drive the outer shell 21 to engage with the limiting groove 18. In this embodiment, the limiting groove 18 is a groove structure opened on one side of the arc surface 12 of the first bracket 14. One end of the limiting groove 18 is sealed to form a limiting surface, and the other end is an open outlet structure. When in use, the soil sensor 23 can be controlled to slide downward relative to the first support 14. The top of the soil sensor 23 gradually separates from the arc surface 12, while the sensor assembly 2 gradually rotates counterclockwise until the outer shell 21 of the sensor assembly 2 slides into the limiting groove 18 from the side with the limiting surface. Then, the soil sensor 23 is controlled to slide downward relative to the outer shell 21 until it is inserted into the soil. When monitoring the soil, the soil will exert an upward reaction force on the soil sensor 23, causing the outer shell 21 to abut against the limiting surface of the limiting groove 18 and lock into the limiting groove 18, thus restricting the movement of the outer shell 21. Therefore, this reaction force can be counteracted, allowing the soil sensor 23 to be smoothly inserted into the soil or even into a deeper position without being prematurely retracted due to the reaction force of the soil.

[0027] In one embodiment, please refer to Figure 1The sensor assembly 2 also includes a connecting plate 24 and a hinge 25. The connecting plate 24 is connected to the housing 21 and is rotatably connected to the hinge plate 22 via the hinge 25. In this embodiment, the hinge plate 22 extends beyond the edge of the mounting surface 11 and is rotatably connected to the connecting plate 24 via the hinge 25, so that the housing 21 has a large rotation space, which can smoothly drive the soil sensor into the receiving space 13 during rotation. In addition, when the top of the soil sensor 23 presses against the arc surface 12, the reaction force exerted by the arc surface 12 on the soil sensor 23 can drive the soil sensor 23 to act on the hinge 25. The hinge 25 exerts an upward oblique reaction force on the soil sensor 23. Finally, the soil sensor 23 can be subjected to torque force during the continuous sliding and rising process, and rotate into the receiving space 13.

[0028] Further, please refer to Figure 4 The hinge 25 includes a rod 251 and two bent portions 252 at both ends of the rod 251. Both bent portions 252 are connected to the hinge plate 22, and the rod 251 is connected to the connecting plate 24. In this embodiment, the two bent portions 252 are both L-shaped and symmetrically arranged. The long sides of the two bent portions 252 are on the same straight line and are not collinear with the rod 251. The rod 251 is offset relative to the straight line containing the long side of the bent portion 252, so that the connecting plate 24 has a large rotation space. The soil sensor 23 has enough space to rotate into the receiving space 13, and the connecting plate 24 is not interfered with by the hinge plate 22 when rotating.

[0029] In one embodiment, please refer to Figure 3 The soil monitoring component 100 also includes a drive mechanism 3 disposed on the housing 21. The drive mechanism 3 is connected to the soil sensor 23 and is used to drive the soil sensor 23 to move up and down. In this embodiment, the drive mechanism 3 serves as the power source for the soil sensor 23 to move up and down, so that the soil sensor 23 can work or be stored, without the need for manual operation of the soil sensor 23, making it convenient to use.

[0030] In one embodiment, please refer to Figure 3 and Figure 5 The drive mechanism 3 includes a servo motor 31, a first gear 32, and a second gear 33 that mesh sequentially. The second gear 33 is threaded onto the soil sensor 23. The servo motor 31 can drive the second gear 33 to rotate through the first gear 32, so that the second gear 33 drives the soil sensor 23 to rise and fall through the thread. In this embodiment, when the servo motor 31 is working, it can drive the first gear 32 to rotate through meshing. The first gear 32 drives the second gear 33 to rotate through meshing. When the second gear 33 rotates, it drives the soil sensor 23 to rise and fall through the thread. The rising or falling is specifically achieved by the second gear 33 rotating in the forward or reverse direction.

[0031] The soil sensor 23 includes a screw 231, a sensing part 232, and a top cover 233. The bottom of the screw 231 is detachably connected to the sensing part 232, allowing the sensing part 232 to be easily installed and removed. When the screw 231 slides downward, it can drive the sensing part 232 into the soil, enabling the sensing part 232 to monitor the soil's temperature, humidity, and other conditions. When the screw 231 rises, it can drive the sensing part 232 out of the soil, ultimately causing the sensing part 232 to be in an inclined state.

[0032] The screw 231 has an external thread, and the aforementioned second gear 33 has an internal thread. The internal thread is threaded onto the external thread, so that the screw 231 and the second gear 33 are threadedly connected. When the second gear 33 rotates, it can drive the screw 231 to slide up and down.

[0033] The screw 231 has a groove 234 along its length. The top cover 233 is threaded to the top of the outer casing 21. The top cover 233 is hollow and can be used for the screw 231 to pass through or retract. The top cover 233 can be regarded as part of the outer casing 21. The inner wall of the top cover 233 is provided with a protrusion 235. The protrusion 235 slides and engages with the groove 234 of the screw 231 to restrict the rotation of the screw 231, so that the screw 231 can be driven to move up and down stably when the second gear 33 rotates.

[0034] Secondly, please refer to Figure 6 , Figure 7 and Figure 8 The present invention also provides an agricultural monitoring vehicle 200, including a vehicle body 4 and the aforementioned soil monitoring component 100. A fixing bracket 1 is provided on the vehicle body 4. Specifically, a screw hole 141 is opened through the first bracket 14, and a screw is threaded through the screw hole 141 to connect to the vehicle body 4, so that the soil monitoring component 100 can be detachably installed on the vehicle body 4.

[0035] In some embodiments, the monitoring vehicle 200 further includes a solar power supply component and a drive component. Multiple rollers 41 are rotatably mounted on the bottom of the vehicle body 4, enabling the vehicle body 4 to move on the ground via the rollers 41. The drive component is connected to the rollers 41 and drives the rollers 41 to rotate, thereby propelling the monitoring vehicle 200 across the farmland. The connection structure between the drive component and the rollers 41 is a well-known and mature structure in the art, and specific details will not be elaborated here. The solar power supply component is connected to the drive component and is used to store electrical energy via solar energy to power the drive component.

[0036] The solar power supply assembly includes a housing 51, a first solar panel 52, and a power mechanism 53. The first solar panel 52 is slidably disposed inside the housing 51. The power mechanism 53 is connected to the first solar panel 52 and is used to drive the first solar panel 52 to rise and fall. When the first solar panel 52 needs to absorb solar energy, it can be driven by the power mechanism 53 to rise and extend out of the housing 51. When the first solar panel 52 is not needed, it can be driven by the power mechanism to lower and store in the housing 51, making it convenient to use.

[0037] In some embodiments, please refer to Figure 7 The power mechanism 53 includes a telescopic rod 531, a first connecting rod 532, and a second connecting rod 533. One end of the first connecting rod 532 is rotatably connected to the housing 51, and the other end is rotatably connected to the second connecting rod 533 and the telescopic rod 531. The other end of the second connecting rod 533 is rotatably connected to the top of the first solar panel 52. The telescopic rod 531 is connected to a corresponding cylinder, and the cylinder drives the telescopic rod 531 to reciprocate, so that the telescopic rod 531 drives the first solar panel 52 to rise and fall through the first connecting rod 532 and the second connecting rod 533.

[0038] In some embodiments, please refer to Figure 8 and Figure 9 A second solar panel 54 is fixedly installed inside the housing 51. The housing 51 is transparent so that the second solar panel 54 can absorb solar energy without extending out of the housing 51. Both sides of the second solar panel 54 can absorb solar energy. The first solar panel 52 can be raised and extended out of the housing 51 to avoid blocking the second solar panel 54, so that both sides of the first solar panel 52 and the second solar panel 54 can absorb solar energy.

[0039] In some embodiments, please refer to Figure 8 and Figure 9An L-shaped protective plate 55 is rotatably mounted inside the housing 51. Besides the top opening, the housing 51 also has an opening on the side furthest from the power mechanism 53. The L-shaped protective plate 55 includes a short plate 551 and a long plate 552 connected together. The short plate 551 is located at the bottom of the housing 51, and the long plate 552 is positioned approximately vertically to cover the side opening of the housing 51. When the first solar panel 52 is inside the housing 51, the bottom of the first solar panel 52 can press down on the short plate 551 to restrict the rotation of the L-shaped protective plate 55. In this embodiment, the second solar panel 54 has an elastic member 56 on the side facing away from the first solar panel 52. When the bottom of the first solar panel 52 presses down on the short plate 551, the long plate 552 is in a vertical position and deforms against the elastic member 56, accumulating elastic force. When the first solar panel 52 rises and extends out of the housing 51, the short plate 551 is released from its restraints, and the elastic element 56 releases its elastic force to drive the long plate 552 to move to the right and tilt. Then, the weight of the long plate 552 drives the entire L-shaped protective plate 55 to continue rotating until the short plate 551 abuts against the first solar panel 52. At this time, the long plate 552 opens the side opening of the housing 51 so that the side of the second solar panel 54 facing away from the first solar panel 52 can absorb solar energy. When the first solar panel 52 descends and is stored in the housing 51, the bottom of the first solar panel 52 presses down on the short plate 551 again to drive the L-shaped protective plate 55 to rotate. The long plate 552 rotates again to close the side opening of the housing 51 and presses against the elastic element 56.

[0040] The bottom of the housing 51 is also provided with a battery box 57, which contains a battery. The battery is connected to the first solar panel 52 and the second solar panel 54. The solar energy absorbed by the first solar panel 52 and the second solar panel 54 can be converted into electrical energy to supply the battery. The battery is connected to the cylinder and drive components on the vehicle body 4 to provide power to these drive components for continued operation.

[0041] In some embodiments, please refer to Figure 8 The monitoring vehicle 200 also includes a camera 6 mounted on the vehicle body. The camera 6 is mounted on a mounting bracket 61 and connected to a second connecting rod 533 via the mounting bracket 61. When the second connecting rod 553 causes the first solar panel 52 to rise, it also causes the camera 6 to rise. The camera 6 monitors the growth and pest and disease status of crops based on image recognition.

[0042] To better understand this invention, the following is combined with... Figures 1 to 9 The technical solution of the present invention will be described in detail below: The soil monitoring component 100 provided by this invention has a fixed bracket 1 that can be installed on an agricultural monitoring vehicle. When the agricultural monitoring vehicle is traveling in the farmland, the soil sensor 23 can be used to monitor the soil. When monitoring is needed, the soil sensor 23 can be controlled to slide down relative to the outer shell 21 to insert into the soil. When monitoring is not needed, the soil sensor 23 can be controlled to slide up. The top of the soil sensor 23 presses against the arc surface of the fixed bracket 1. Combined with the weight of the soil sensor 23 itself and the force at the hinge plate 22, the arc surface can apply a torsional force to the soil sensor 23 to drive the soil sensor 23 to rotate toward the receiving space 13, so that it is located in the receiving space 13 and in an inclined storage state. At this time, the bottom of the soil sensor 23 is less likely to touch obstacles when the agricultural monitoring vehicle is traveling in the farmland, which can effectively protect the soil sensor 23.

[0043] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
