Description

Technical Field

[0001] This utility model relates to the field of soil monitoring technology, and in particular to a forest soil monitoring device. Background Technology

[0002] In fields such as forest ecosystem research, forestry resource management, and ecological environmental protection, accurate monitoring of various indicators of forest soil is of paramount importance. Soil parameters such as nutrient content, moisture, and pH directly affect the growth of forest vegetation, the stability of the ecosystem, and key ecological processes such as carbon cycling.

[0003] Currently, existing forest soil monitoring devices have many inconveniences in practical applications. Traditional monitoring methods often require manually excavating soil profiles and then analyzing soil samples using testing instruments. This method is not only time-consuming and labor-intensive, but also damages the natural structure of forest soil, affecting the accuracy of monitoring results.

[0004] Existing monitoring devices often lack good human-machine interaction in their structural design. The position of the operating handle and the lifting control method are not reasonable enough, which can easily cause operator fatigue during long-term use and affect monitoring efficiency. At the same time, the control of the drive components and telescopic components is not integrated enough, making it difficult to achieve automated and precise operation, and thus failing to meet the requirements of modern forest soil monitoring for high efficiency, convenience and accuracy.

[0005] Therefore, developing a forest soil monitoring device that can be stably inserted into the soil, flexibly adjust the position of the detection probe, and is easy to operate and precisely controlled has become the key to solving the current problems in forest soil monitoring. Utility Model Content

[0006] The purpose of this invention is to address the deficiencies in the existing technology by proposing a forest soil monitoring device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A forest soil monitoring device includes a chassis with a through hole. A drive tube is positioned above the through hole, and an outer cylinder is housed within the drive tube. An inner rod is slidably connected within the outer cylinder. A conical head is fixedly connected to the bottom of the inner rod, with the bottom diameter of the conical head being the same as the outer diameter of the outer cylinder. The bottom of the inner rod has a horizontally arranged sliding hole and a longitudinally arranged through hole. A sliding rod is slidably connected within the sliding hole. A detection probe is fixedly connected to one end of the sliding rod, and a traction rope is fixedly connected to the other end. A spring is positioned between the detection probe and the sliding hole. The end of the traction rope is connected to a telescopic rod, which is fixedly connected to the through hole. A lower handle is fixedly connected to the outer wall of the outer cylinder, and an upper handle is fixedly connected to the outer wall of the inner rod. The upper and lower handles are connected via a lifting rod. The lifting rod, the telescopic rod, and the drive tube are all controlled by a control assembly.

[0009] Furthermore, a number of spikes are fixedly connected to the chassis, and the spikes are arranged in a circular array.

[0010] Furthermore, multiple sets of anti-slip wheels are rotatably connected to the drive tube. The working surface of the anti-slip wheels is an arc surface and is adapted to the outer wall of the outer cylinder. The anti-slip wheels are controlled by a drive motor.

[0011] Furthermore, the outer cylinder is provided with two sets of symmetrically arranged lower handles, the inner rod is provided with two sets of symmetrically arranged upper handles, one end of the lifting rod is connected to the lower handles, and the other end is connected to the upper handles.

[0012] Furthermore, the detection probe is provided in two sets, namely a pH detection probe and a humidity detection probe; both sets of detection probes are connected to an external signal receiving component.

[0013] Furthermore, a receiving groove is provided on one side of the through hole based on the sliding hole principle, and the receiving groove is adapted to the probe.

[0014] Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The detection probe is slidably connected to a sliding hole at the bottom of the inner rod via a sliding rod, with a spring connecting the probe and the hole. The other end of the sliding rod is connected to a telescopic rod inside a through hole via a traction rope. When the telescopic rod extends or retracts, the traction rope and spring move the sliding rod within the sliding hole, extending and retracting the detection probe. Under the action of the spring, the extended probe better conforms to the soil, ensuring tight contact. Under the action of the traction rope, the detection probe can retract into the inner rod and be protected by the outer cylinder, preventing friction with the soil during the raising and lowering of the outer cylinder.

[0017] The lifting mast, telescopic mast, and drive tube are all centrally controlled by a control component, achieving integrated and automated operation of each component. The control component can precisely regulate the driving force of the drive tube, the lifting amplitude of the lifting mast, and the extension length of the telescopic mast, thereby accurately controlling the insertion depth of the device, the extension status of the detection probe, etc., ensuring that each operation is performed according to preset requirements. This significantly improves the accuracy and reliability of the monitoring process, meeting the demands of modern forest soil monitoring for high efficiency and precision.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0027] Reference Figures 1-5 A forest soil monitoring device includes a chassis 6 with a through hole. A drive tube 5 is installed above the through hole, and an outer cylinder 4 is installed inside the drive tube 5. An inner rod 2 is slidably connected inside the outer cylinder 4. A conical head 9 is fixedly connected to the bottom of the inner rod 2. The bottom diameter of the conical head 9 is the same as the outer diameter of the outer cylinder 4. A horizontally arranged sliding hole and a longitudinally arranged through hole are opened at the bottom of the inner rod 2. A sliding rod 13 is slidably connected inside the sliding hole. A detection probe is fixedly connected to one end of the sliding rod 13, and a traction rope 14 is fixedly connected to the other end. A spring 12 is installed between the detection probe and the sliding hole. The end of the traction rope 14 is connected to a telescopic rod 10, which is fixedly connected to the through hole. A lower handle 8 is fixedly connected to the outer wall of the outer cylinder 4, and an upper handle 7 is fixedly connected to the outer wall of the inner rod 2. The upper handle 7 and the lower handle 8 are connected by a lifting rod 3. The lifting rod 3, the telescopic rod 10, and the drive tube 5 are all controlled by a control component 1.

[0028] The detection probe 11 is slidably connected to a sliding hole at the bottom of the inner rod 2 via a slide rod 13, and a spring 12 is provided between the detection probe and the sliding hole. The other end of the slide rod 13 is connected to a telescopic rod 10 inside a through hole via a traction rope 14. When the telescopic rod 10 extends or retracts, the slide rod 13 moves within the sliding hole via the traction rope 14 and the spring 12, thus extending and retracting the detection probe. Under the action of the spring 12, the extended detection probe can better conform to the soil, ensuring tight contact. Under the action of the traction rope 14, the detection probe can retract into the inner rod 2 and be protected by the outer cylinder 4, preventing friction with the soil during the raising and lowering of the outer cylinder 4.

[0029] The lifting rod 3, telescopic rod 10, and drive tube 5 are all centrally controlled by the control component 1, realizing the integration and automation of the operation of each component. The control component 1 can precisely adjust the driving force of the drive tube 5, the lifting amplitude of the lifting rod 3, and the extension length of the telescopic rod 10, thereby accurately controlling the insertion depth of the device, the extension state of the detection probe, etc., ensuring that each operation is carried out according to the preset requirements, greatly improving the accuracy and reliability of the monitoring process, and meeting the needs of modern forest soil monitoring for high efficiency and accuracy.

[0030] In other preferred embodiments, a plurality of spikes are fixedly connected to the chassis 6, arranged in a circular array. When the device is placed on the forest floor, the spikes insert into the soil. The circular distribution ensures that each spike bears a portion of the device's weight and the forces generated during operation, effectively preventing the device from tilting or shaking due to uneven force during monitoring. Especially in uneven terrain, with fallen leaves or soft soil in forests, this circular array of spikes firmly grips the ground, providing a stable support foundation for the entire device. This ensures that components such as the outer cylinder 4 and inner rod 2 remain stable when inserted into the soil and during detection operations, preventing the insertion accuracy of the detection probe and the accuracy of the monitoring data from being affected by device shaking.

[0031] In other preferred embodiments, multiple sets of anti-slip wheels are rotatably connected to the drive tube 5. The working surface of the anti-slip wheels is an arc surface and is adapted to the outer wall of the outer cylinder 4. The anti-slip wheels are controlled by a drive motor.

[0032] The curved surface of the anti-slip wheels adapts to the outer wall of the outer cylinder 4, increasing the contact area and improving the fit. Multiple sets of anti-slip wheels work together to stably clamp the outer cylinder 4 within the drive tube 5 from multiple directions. When the drive motor drives the anti-slip wheels to rotate and raise or lower the outer cylinder 4, it effectively prevents the outer cylinder 4 from shifting, shaking, or jamming, ensuring smooth movement along the set trajectory. This, in turn, ensures the precise movement of the inner rod 2, the bottom conical head 9, the detection probe, and other components, providing a stable foundation for successful soil monitoring. The anti-slip wheel design enhances friction with the outer wall of the outer cylinder 4, especially during the raising and lowering process, preventing relative slippage between them. The anti-slip wheels, controlled by the drive motor, allow for automated control of the raising and lowering operation of the outer cylinder 4 via the control component 1, eliminating the need for manual adjustment and reducing the workload of operators.

[0033] In other preferred embodiments, the outer cylinder 4 is provided with two sets of symmetrically arranged lower handles 8, and the inner rod 2 is provided with two sets of symmetrically arranged upper handles 7. One end of the lifting rod 3 is connected to the lower handle 8, and the other end is connected to the upper handle 7. The symmetrically connected lifting rods 3 can evenly transmit the force to the outer cylinder 4 and the inner rod 2, avoiding local stress concentration caused by unilateral connection.

[0034] In other preferred embodiments, two sets of detection probes are provided: a pH detection probe and a humidity detection probe; both sets of probes are connected to an external signal receiving component. These two sets of probes of different types can simultaneously detect the two key indicators of forest soil pH and humidity, acquiring multiple soil parameters without changing probes. This provides a more comprehensive reflection of soil conditions, offering richer basic data for forest ecological research and vegetation management, avoiding the limitation of a single probe detecting only one indicator, and improving monitoring efficiency. The connection between the two sets of probes and the external signal receiving component enables real-time transmission of detection data. The external signal receiving component can centrally process, analyze, and store the transmitted signals.

[0035] A soil pH sensor such as the SEN0161 can be used. This type of probe typically operates based on the potentiometric principle. The probe contains a reference electrode and a measuring electrode. When the probe is inserted into the soil, hydrogen ions in the soil react with the surface of the measuring electrode, generating a potential difference. The reference electrode provides a stable reference potential, and the potential difference between the two changes with variations in the concentration of hydrogen ions in the soil (i.e., pH). By measuring this potential difference and converting it into a corresponding electrical signal, which is transmitted to an external signal receiving component, the soil's pH value can be obtained after processing.

[0036] A soil moisture sensor, such as the YL-69, can be used. This type employs a resistive principle. When the probe's two electrodes are inserted into the soil, their conductivity varies depending on the soil's moisture content. When the soil moisture is high, the water content is high, resulting in strong conductivity and low resistance between the electrodes; conversely, when the soil moisture is low, conductivity is weak, leading to higher resistance. The moisture detection probe measures the change in resistance between the two electrodes and converts this resistance signal into a corresponding electrical signal, which is then sent to an external signal receiving component. After processing, the soil moisture information is obtained.

[0037] In other preferred embodiments, a receiving groove is provided on one side of the through hole based on the sliding hole principle, and the receiving groove is adapted to the probe.

[0038] The main control module of control component 1 typically uses a microcontroller (such as the STM32 series) or a PLC (Programmable Logic Controller) as the core control unit. It is responsible for receiving input signals (such as operation commands and sensor feedback signals) and outputting control signals according to a preset program or algorithm to coordinate the actions of each actuator. The drive module includes components such as motor drivers, which are connected to the drive motor of drive tube 5, the drive component of lifting rod 3 (such as an electric push rod motor), and the drive component of telescopic rod 10 (such as a micro stepper motor). The drive module converts the weak electrical control signals output by the main control module into strong electrical drive signals, providing stable power output to each power component and ensuring its precise operation according to commands. The signal receiving and processing module includes signal conditioning circuitry and an A / D converter. It receives analog electrical signals transmitted from the pH and humidity detection probes, filters and amplifies the signals, and converts them into digital signals for transmission to the main control module, ensuring the accuracy and stability of the detection data. Power module: Provides a stable power supply for control component 1 and each controlled component. It usually uses a rechargeable lithium battery or an external power supply and has overcurrent and overvoltage protection functions to ensure the safe and reliable operation of the device.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
