Description

Technical Field

[0001] This utility model belongs to the field of orchard soil monitoring technology, and in particular relates to a real-time monitoring device for orchard soil moisture. Background Technology

[0002] An orchard refers to agricultural land that is planned and systematically managed to cultivate fruit trees for the purpose of obtaining fruit or other fruit production. Its core characteristic is the concentrated cultivation of woody or perennial fruit trees, achieving economic output through agronomical measures such as land preparation, pruning, irrigation, and pest and disease control. The establishment of an orchard requires consideration of climate adaptability, soil conditions, and long-term management; essentially, it is an agricultural production system that integrates natural growth patterns with human intervention.

[0003] In orchard management, soil moisture monitoring is a crucial step in ensuring healthy tree growth and optimizing irrigation. Traditional manual insertion-based monitoring methods face numerous challenges and limitations in practice. When monitoring personnel need to insert probes deep into the soil, it not only requires significant physical exertion but also significantly reduces work efficiency. Especially in large orchards, this repetitive labor severely impacts monitoring frequency and coverage.

[0004] The instantaneous impact force experienced by the probe during forced insertion can loosen or damage internal precision electronic components. Orchard soil often contains hard objects such as gravel and broken branches left over from cultivation, which the probe will rigidly collide with during random insertion. Frequent insertion and removal operations over a long period can also cause probe surface wear and electrode oxidation, thus affecting measurement accuracy. Seasonal factors such as soil compaction due to drought or soil hardening during freezing periods further increase the difficulty of insertion. Utility Model Content

[0040] Please see Figures 1 to 12 The present invention provides two embodiments:

[0041] Example 1: A real-time soil moisture monitoring device for orchards, comprising:

[0042] The cylinder 3 includes: a through hole 11 opened at the top of the cylinder 3;

[0043] The drill pipe 9 is slidably connected inside the through hole 11 and includes: a long pipe 10 fixed to the upper surface of the drill pipe 9, a gear 8 fixed to the upper end of the long pipe 10, and a gear 6 meshing with the gear 8.

[0044] The bracket 7, fixed to the upper surface of the gear 8, includes: a spring 31 installed inside the bracket 7, a mounting plate 30 fixed to the bottom end of the spring 31, a connecting rod 27 fixed to the bottom end of the mounting plate 30, a mounting rod 28 fixed to the bottom end of the connecting rod 27, a soil moisture monitoring probe 43 fitted and installed on the side wall of the mounting rod 28, and a drill bit 29 fixed to the bottom end of the mounting rod 28.

[0045] A fixing plate 4 is fixed to the upper end of the outer wall of the cylinder 3. A long plate 5 is fixed to the upper surface of the fixing plate 4. A long groove 18 is opened on one side of the long plate 5. A connecting block 20 is inserted into the long groove 18. A threaded hole 29 is vertically opened on the connecting block 20. A round hole 21 is opened on the upper surface of the long plate 5. A motor 22 is fixed to the upper surface of the long plate 5. The bottom end of the drive shaft of the motor 22 extends into the round hole 21. A screw 17 is fixed to the bottom end of the drive shaft of the motor 22. The bottom end of the screw 17 passes through the threaded hole 29 and is threaded. A mounting bracket 38 is fixed to one side of the connecting block 20.

[0046] Motor 22 drives connecting block 20 to move within long slot 18 via screw 17, allowing drill pipe 9 to move up and down as needed. This facilitates drilling the drill pipe 9 into different depths of orchard soil, enabling moisture monitoring at different soil depths. Electricity replaces manual gear adjustment, improving deployment efficiency.

[0047] Mounting bracket 2 38 has a mounting groove 2 39 at its front end and a through hole 40 on its upper surface. Mounting bracket 1 23 is fixed on the upper surface of mounting bracket 2 38. Mounting bracket 1 23 has a mounting groove 37 at its front end and a round hole 25 on its upper surface. Motor 2 24 is fixed on the upper surface of mounting bracket 1 23. The bottom end of the drive shaft of motor 2 24 extends into the round hole 25. A rotating shaft 26 is fixed at the bottom end of the drive shaft of motor 2 24. The bottom end of the rotating shaft 26 extends into the through hole 40. A gear 1 6 is fixed at the bottom end of the through hole 40. Gear 1 6 is rotatably connected to mounting groove 2 39. Gear 2 8 is rotatably connected to mounting groove 2 39.

[0048] The transmission shaft 24 of the motor 24 is fixed to the rotating shaft 26, which provides power for the rotation of the rotating shaft 26 and the gear 1 6. At the same time, it can drive the gear 2 8 and the drill pipe 9 to rotate, so that the drill pipe 9 can be drilled into the orchard soil at different depths, and the humidity of the orchard soil at different depths can be monitored.

[0049] Motor 24 drives gear 6 through shaft 26, providing sufficient torque to overcome hard soil resistance and reduce the risk of stuck drill bit.

[0050] Motor 1 (22) and Motor 2 (24) are connected to a conventional power source, which provides power for their operation.

[0051] Motor 1 (22) and Motor 2 (24) are servo motors. Servo motors can rotate in both directions as needed. Their core structure consists of three main parts: the motor body, the encoder, and the controller. The motor body typically uses a permanent magnet synchronous motor or a brushless DC motor. The rotor uses high-performance permanent magnets to enhance the magnetic field strength, while the stator windings are arranged in a specific phase, achieving precise control through electronic commutation. The encoder, as a position feedback element, is typically a photoelectric or magnetic encoder that monitors the rotor position in real time and feeds the signal back to the controller, forming a closed-loop control. The controller receives external commands, combines them with encoder feedback data, and adjusts the current phase and amplitude of the motor windings using PID algorithms or other control strategies, thereby precisely controlling the rotor's motion.

[0052] The working principle of a servo motor is based on a closed-loop feedback control mechanism. When the controller receives a target position or speed command, it compares it with the actual value fed back by the encoder, calculates the error signal, and outputs the corresponding three-phase current to the motor windings through the drive circuit, generating a rotating magnetic field to pull the rotor. During this process, the encoder continuously detects the rotor position, and the controller dynamically adjusts the current to eliminate the error until the actual value matches the command.

[0053] Gear 6 is rotatably connected to mounting groove 39, and gear 8 is rotatably connected to mounting groove 39, so that gear 6 and gear 8 can maintain horizontal center alignment, making it easy for gear 6 to drive gear 8 to rotate.

[0054] The bottom end of the cylinder 3 passes through the mounting plate 2. The upper surface of the mounting plate 2 is provided with a mounting hole 12. The cylinder 3 passes through the mounting hole 12 and is fixed. Multiple positioning rods 1 are fixed in a ring on the lower surface of the mounting plate 2.

[0055] The ring positioning rod 1 is inserted into the soil pre-fixing device to prevent the cylinder 3 from shifting during drilling, ensuring the verticality of the borehole and enabling rapid positioning; the mounting plate 2 increases the contact area with the ground, suppresses vibration, improves drilling accuracy, and enhances overall stability.

[0056] In this embodiment, when real-time monitoring of orchard soil moisture is required, multiple positioning rods 1 are inserted into the orchard soil. Motor 24 is activated, causing the rotating shaft 26 and gear 6 to rotate as needed. Gear 6 drives gear 8, the long tube 10, and the drill pipe 9 to rotate, causing the drill pipe 9 to rotate downwards into the orchard soil. Simultaneously, motor 22 is activated, causing the screw 17 to rotate. The connecting block 20, mounting bracket 38, and gear 6 can move up and down as needed. Gear 6 and gear 8 maintain horizontal center alignment and meshing connection. The drill pipe 9 rotates downwards to different depths within the orchard soil. This achieves the effect of allowing the drill pipe 9 to be drilled into the orchard soil at different depths as needed, facilitating moisture monitoring at different depths in the orchard soil.

[0057] Example 2:

[0058] The difference between this embodiment and Embodiment 1 is that:

[0059] The gear 2 has a mounting hole 2 16 on its lower surface. The upper end of the outer wall of the long tube 10 extends into the mounting hole 2 16 and is fixed. The drill tube 9 has a through hole 2 13 on its upper surface. The inner wall of the through hole 2 13 has a tube groove 36 at the bottom. The inner wall of the tube groove 36 has a through hole 3 15 at the bottom. The long tube 10 has a tube hole 14 on its upper surface.

[0060] The long tube 10 is rigidly fixed to the gear 8 through the mounting hole 2 16, ensuring that the rotational force is transmitted to the drill tube 9 without loss, avoiding slippage or idling, so that the power can be transmitted efficiently.

[0061] Through hole 2 13, tube groove 36, through hole 3 15 are vertically aligned with the center of tube hole 14;

[0062] The second through hole 13, the groove 36, the third through hole 15 and the vertical center of the pipe hole 14 are aligned to ensure that the connecting rod 27 and the soil moisture monitoring probe 43 move in a straight line, avoiding jamming caused by deflection, so that the power can be accurately guided.

[0063] The front end of the bracket 7 has a groove 34, and springs 31 are fixed on both sides of the top of the inner wall of the groove 34.

[0064] Spring 31 provides power for the downward movement of drill bit 29 and soil moisture monitoring probe 43, allowing drill bit 29 and soil moisture monitoring probe 43 to be inserted into the soil for easy monitoring of soil moisture.

[0065] The soil moisture monitoring probe 43 is a sensor device used to measure the moisture content in soil. Its core structure consists of a needle body, an electrode assembly, and a signal processing module. The needle body is typically made of a slender rod-shaped structure from corrosion-resistant metal or ceramic materials, with a special surface treatment to prevent electrolytic effects and chemical corrosion. The internal electrode assembly consists of one or more pairs of stainless steel or gold-plated metal electrodes, which are arranged parallel to each other or in a ring along the needle body axis. The electrode spacing is precisely designed to ensure a uniform electric field distribution. A water-permeable but corrosion-resistant filter layer may be wrapped around the electrodes, allowing water to permeate freely while preventing soil particles from entering. The top of the needle body has a waterproof and sealed terminal block, which connects to a signal converter via a shielded cable. Some high-end models also integrate a temperature sensor for compensation calibration.

[0066] Its working principle is based on dielectric constant measurement or impedance analysis techniques. When the needle is inserted into the soil, an alternating electric field of a specific frequency is formed between the electrodes. Water in the soil, as polar molecules, will become polarized under the influence of the electric field, causing changes in the system's capacitance or impedance. The dielectric constant method estimates the water content by measuring the change in capacitance between the electrodes, because the dielectric constant of water is much higher than that of dry soil, and the capacitance value is non-linearly positively correlated with the water content.

[0067] The bottom end of the connecting rod 27 extends into the pipe groove 36 through the pipe hole 14 and the second through hole 13, the soil moisture monitoring probe 43 extends into the pipe groove 36, and the drill bit 29 extends into the third through hole 15.

[0068] When the soil moisture monitoring probe 43 extends and retracts within the trench 36, the drill bit 29 can block the through hole 3 15 to prevent soil from entering the trench 36 and keep the trench 36 clean.

[0069] The drill bit 29 first contacts the soil to drill a hole, and the soil moisture monitoring probe 43 then extends in, completely avoiding direct impact, thus protecting the soil moisture monitoring probe 43.

[0070] A power supply component 41 is installed on one side of the inner wall of the tube 36, and a signal transmitting component 42 is installed on the other side of the inner wall of the tube 36.

[0071] The power supply component 41, serving as the core energy supply unit for the orchard soil moisture monitoring device, adopts a modular integrated design and mainly consists of a power supply compartment, an energy storage module, a voltage regulator circuit, and an intelligent management unit. The power supply compartment uses a sealed aluminum alloy shell, with a high-energy-density lithium thionyl chloride battery pack fixed inside via rubber buffer pads. The intelligent management unit is equipped with a coulomb metering chip to monitor the battery level in real time and dynamically adjusts the output voltage using a temperature compensation algorithm. When the battery voltage is detected to be below a threshold, a low-battery warning is sent via the signal transmitting component 42.

[0072] Its working principle is based on an adaptive energy management mechanism. During the drilling stage of the drill pipe 9 rotating and descending, the power supply component 41 is in standby mode, maintaining only basic power consumption. When the soil moisture monitoring probe 43 reaches the measurement depth, the Hall sensor detects the signal that the mounting rod 28 has been positioned and immediately switches to the working mode. First, a pulse power supply is provided to the dielectric constant measurement circuit of the probe, and then a transient power supply is provided to the signal transmission component 42.

[0073] The signal transmitting component 42 adopts a multi-mode fusion wireless transmission architecture, the core of which consists of a radio frequency processing unit, an antenna array, and a protocol stack coprocessor. It can transmit monitored soil moisture data.

[0074] The bracket 7 has a three-round hole 33 on its upper surface. The mounting plate 30 has a screw 35 fixed on its upper surface. The top of the screw 35 passes through the three-round hole 33 and the top of the screw 35 passes through the nut 32 and is threaded together.

[0075] The top of the screw 35 passes through the nut 32 and is threaded, which allows the compressed spring 31 to be locked.

[0076] In this embodiment, when the drill pipe 9 enters the orchard soil to a suitable depth and humidity is monitored, the nut 32 is rotated so that the nut 32 is removed from the screw 35. The spring 31 deforms downward elastically, and the connecting rod 27, the mounting rod 28, the soil humidity monitoring probe 43, and the drill bit 29 move downward, so that the drill bit 29 and the soil humidity monitoring probe 43 are inserted into the soil. The soil humidity monitoring probe 43 can monitor the soil humidity, which achieves the effect of preventing soil from entering the drill pipe 9 and clogging it, while also protecting the soil humidity monitoring probe 43.

[0077] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
