Description

Technical Field

[0001] This utility model patent relates to the field of agricultural equipment technology, specifically to a soil moisture detector for agricultural meteorology. Background Technology

[0002] In the fields of modern agricultural production and meteorological research, soil moisture detection is a crucial foundational task. Soil moisture directly affects crop growth and development, the occurrence of pests and diseases, and the stability of the agricultural ecosystem. Accurate and efficient acquisition of soil moisture data is of key significance for scientific irrigation, precision fertilization, and early warning of agricultural meteorological disasters. As the core equipment for achieving this function, the performance and technical level of soil moisture detectors have received widespread attention.

[0003] Currently, most commercially available soil moisture meters employ a probe-type structure. By inserting a probe into the soil, sensors detect physical parameters such as the soil's dielectric constant and resistance, thereby calculating the soil moisture value. The purpose of these meters is to provide real-time soil moisture data for agricultural production, assisting farmers in making irrigation decisions to achieve water conservation, increased yields, and improved agricultural production efficiency.

[0004] However, existing technologies have several drawbacks: First, traditional probe-type detectors are prone to bending or breaking when encountering hard soil or underground obstacles during insertion, affecting detection accuracy and equipment lifespan. Second, most detectors lack effective self-protection designs. During long-term outdoor use, factors such as acidic and alkaline substances in the soil, microbial erosion, and mechanical friction can cause wear and corrosion on parts such as the equipment base, leading to decreased equipment stability. Third, existing detectors have limited detection range and depth, making it difficult to meet the diverse needs of different crops at different growth stages for soil moisture detection at different depths.

[0005] Based on the above needs, there is an urgent need to design a robust and accurate agricultural meteorological soil moisture detector. Summary of the Invention

[0006] To address some or all of the aforementioned technical problems, this application provides an agricultural meteorological soil moisture detector, which has the technical advantage of being able to monitor soil at different depths and effectively protect the probe.

[0007] An agricultural meteorological soil moisture detector includes: a base with a chamfered edge on its lower end face; an equipment frame mounted on the base; a hydraulic rod mounted on the equipment frame; a hollow anchor connected to the drive end of the hydraulic rod, with a detection window on the side wall of the hollow anchor and an opening in the base for the hollow anchor to penetrate; an unfolding structure housed within the hollow anchor, the unfolding structure including a reference rod, a traveling rod perpendicularly penetrating the reference rod, a return spring sleeved on the traveling rod, a drive rod driven by the traveling rod, and a micro-pump connected to the drive rod; and a humidity detector with its probe located at the working end of the traveling rod; wherein the two ends of the return spring are respectively fixedly connected to the reference rod and the drive end of the traveling rod.

[0008] By adopting the above technical solution: 1. The base serves as the foundation of the entire device, and its chamfered lower edge design facilitates movement resistance during fine-tuning of the device's placement. 2. The equipment frame is securely mounted on the base, providing a reliable support foundation for the hydraulic rod. 3. The hydraulic rod is mounted on the equipment frame, and its drive end is connected to the hollow anchor, enabling it to drive the hollow anchor to move up and down, thus achieving soil detection at different depths. 4. The micro-pump drives the moving rod to one side, causing the travel rod connected to it to move horizontally, which in turn affects the relative movement of the probe towards the outside of the detection window, allowing the probe to extend out of the detection window for soil moisture detection under the action of the unfolding structure.

[0009] When soil moisture needs to be detected, the hydraulic rod activates, pushing the hollow anchor downwards to the target depth. Subsequently, the micro-pump drives the drive rod, which in turn moves the connected travel rod horizontally. Overcoming the resistance of the return spring, the travel rod moves relative to the reference rod, passing through the detection window to insert the probe into the soil. The probe senses the relevant physical parameters of soil moisture and transmits them to the moisture detector, completing the moisture detection. After the detection is complete, the micro-pump stops working, and under the elastic force of the return spring, the travel rod retracts the probe into the hollow anchor. Finally, the hydraulic rod drives the hollow anchor to retract.

[0010] Optionally, the bottom surface of the base is sequentially coated with a wear-resistant coating, wear marking paint, and anti-corrosion paint. The wear marking paint is red, and the thickness of the wear-resistant coating and the wear marking paint is not less than 5 mm.

[0011] By adopting the above technical solution, in terms of structural relationship, the wear-resistant coating, as the bottom layer, is in direct contact with the soil, providing basic wear-resistant protection for the base; the wear indicator paint covers the wear-resistant coating, which can intuitively reflect the wear condition of the wear-resistant coating; and the anti-corrosion paint, as the surface layer, isolates external corrosive substances from contact with the base.

[0012] Optionally, the base is provided with through holes for mounting ground anchors, and there are multiple through holes, which are inclined.

[0013] By adopting the above technical solution, multiple inclined through holes cooperate with the ground anchor to form a stable anchoring structure. Structurally, the multiple inclined through holes are evenly distributed in the base, providing a channel for the installation of the ground anchor. After the ground anchor is inserted into the through hole, it tightly engages with the soil, and the inclination angle makes the force direction of the ground anchor and the direction of the external force that the detector may experience form a more reasonable mechanical relationship, enhancing the overall pull-out resistance and overturning resistance.

[0014] The inclined ground anchors counteract the vertical forces generated during device operation. The tensile or thrust forces acting on the anchors are decomposed into vertical and horizontal components, and the soil's resistance to the inclined anchors effectively counteracts these components, keeping the detector stable. The inclined anchors also firmly secure the detector through soil resistance, preventing displacement or tipping.

[0015] Optionally, the equipment frame includes a support column disposed on the base and a structural ring connected to the support column. Multiple support columns and multiple structural rings are provided. The multiple support columns are arranged in a ring and fixedly connected to the multiple structural rings. The multiple structural rings are arranged sequentially from top to bottom and fixedly connected to each other.

[0016] By adopting the above technical solution, multiple pillars are vertically installed on the base and evenly distributed in a ring to form the basic skeleton of the equipment frame. This ring distribution can evenly distribute external forces. Multiple structural rings are arranged sequentially from top to bottom, and each structural ring is fixedly connected to all pillars, so that the pillars constrain each other and cooperate in bearing forces, forming a stable spatial three-dimensional frame structure, which enhances the overall rigidity and stability.

[0017] When the detector is working, the hydraulic rod drives the hollow anchor to detect soil moisture, which generates significant force and vibration. The ring-shaped support of the equipment frame can evenly distribute the vertical and horizontal forces transmitted by the hydraulic rod onto the base, avoiding excessive local stress; while the multi-layered ring structure, through its fixed connection with the support, restricts the lateral displacement and deformation of the support, enhancing the overall torsional and bending resistance of the equipment frame.

[0018] Optionally, the fixed port of the hydraulic rod is fixedly installed at the junction of the structural ring and the support column, and no fewer than three hydraulic rods are provided.

[0019] By adopting the above technical solution, the fixed port of the hydraulic rod is precisely installed at the junction of the structural ring and the support column. This junction is a key node for force transmission of the equipment frame, with high structural strength and good stability. The setting of no less than 3 hydraulic rods forms a stable triangular or polygonal layout, and the multiple hydraulic rods work together to evenly distribute the force.

[0020] When soil moisture testing is required, the hydraulic rods activate, transmitting power to the hollow anchor via hydraulic transmission. This drives the hollow anchor to insert downwards into the soil or retract upwards. Because the hydraulic rods are fixed at the junction of the structural ring and the support column, this point can withstand the enormous thrust and tension generated by the hydraulic rods, distributing the force transmitted by the hydraulic rods evenly to the base and surrounding soil through the structural ring and support column. Multiple hydraulic rods work together to maintain the hollow anchor's stable and vertical descent during soil insertion, preventing tilting; during retraction, they also lift synchronously, preventing the hollow anchor from swaying. When encountering uneven soil resistance, the multiple hydraulic rods can automatically adjust their output pressure according to the actual force conditions, ensuring stable operation of the hollow anchor.

[0021] Optionally, the hydraulic rod is fixedly connected to the drive end of the hollow anchor, and a shower port is provided inside the tail end face of the hollow anchor. The tail end of the shower port passes through the tail of the hollow anchor, and the shower port and the micro pump are respectively located on both sides of the reference rod.

[0022] By adopting the above technical solution, the shower interface at the hollow anchor tail is installed through, reserving a channel for external water source access. The shower interface and the micro-pump are located on opposite sides of the reference rod, so they do not interfere with each other.

[0023] Optionally, the travel rod and the probe are disposed within the projection of the opening of the detection window, and a slot is provided at the tail end of the hollow anchor; the lead wires of the multiple probes pass through the slot and are connected to the body of the humidity detector, the body being mounted on the base; the drive circuit of the micro-pump passes through the slot and is connected to the control structure, the control structure being connected to the body of the humidity detector and the multiple hydraulic rods respectively.

[0024] By adopting the above technical solution, the detection window provides an operating channel for the travel rod and the probe. Its opening projection accurately covers the travel rod and the probe, ensuring that the probe can extend and penetrate into the soil without obstruction. The slot at the end of the hollow anchor serves as a dedicated channel for the wire and the drive circuit, allowing the probe's lead wire and the drive circuit of the micro pump to pass through in an orderly manner and connect with the humidity detector body and control structure on the base. All components form a closely coordinated layout inside and outside the hollow anchor.

[0025] Optionally, the shower interface is connected to a water supply pipeline.

[0026] Optionally, the shower interface is connected in sequence to a water pump and a water storage tank.

[0027] By adopting the above technical solution, when a large amount of soil enters the hollow anchor after multiple operations, it can be flushed through the rinsing interface.

[0028] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects of an agricultural meteorological soil moisture detector:

[0029] The base is equipped with inclined ground anchor holes to enhance the stability of the equipment in different terrains.

[0030] The equipment frame adopts a ring-shaped distribution structure combining multiple pillars and structural rings to provide stable support for the hydraulic rods and ensure the stable operation of the hollow anchor during the testing process.

[0031] The combination of hydraulic rod and hollow anchor enables the detection of soil at different depths. Furthermore, the ingenious integration of the detection window on the side wall of the hollow anchor with the unfolding structure and the humidity detector probe allows for accurate detection of soil moisture without damaging the original soil structure.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model patent clearer, the technical solutions of the embodiments of this utility model patent will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model patent, not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model patent are within the scope of protection of this utility model patent.

[0041] This application discloses a soil moisture device for agricultural meteorology.

[0042] Referring to the accompanying drawings, an agricultural meteorological soil moisture device includes a base 1, an equipment frame, a hydraulic rod 3, a hollow anchor 4, an unfolding structure, and a moisture detector.

[0043] The base 1 is made of steel plate with a chamfered edge on the lower end face. An opening 42 is provided in the base 1 for the hollow anchor 4 to pass through.

[0044] The equipment frame is mounted on the base 1. The hydraulic rod 3 is mounted on the equipment frame. The drive end of the hydraulic rod 3 is connected to the tail end of the hollow anchor 4. A detection window 41 is provided on the side wall of the hollow anchor 4.

[0045] The hollow anchor 4 is equipped with an unfolding structure. The unfolding structure includes a reference rod 5, a traveling rod 6 that penetrates the reference rod 5 vertically, a return spring 7 sleeved on the traveling rod 6, a drive rod 8 that is driven and connected to the traveling rod 6, and a micro pump 9 that is connected to the drive rod 8. The reference rod 5 is threadedly fixed to the tail end face of the hollow anchor 4, and the two ends of the return spring 7 are fixedly connected to the drive ends of the reference rod 5 and the traveling rod 6, respectively.

[0046] The humidity detector probe 10 is installed at the working end of the travel rod 6.

[0047] One side of the drive rod 8 slides against the inner wall of the hollow anchor 4. The reference rod 5 is a rectangular plate, and the length of the traveling rod 6 penetrating the reference rod 5 is not less than 1 / 3 of the inner diameter of the hollow anchor 4. The traveling rod 6 and the probe 10 are installed within the projection of the opening 42 of the detection window 41.

[0048] The opening angle 42 of the detection window 41 is less than 90 degrees. (Based on the center of the hollow anchor 4)

[0049] When the device is in operation, the operating principle of an agricultural meteorological soil moisture device is as follows:

[0050] First, the device is placed in the target detection area. The steel plate base 1 provides solid support for the entire device due to its high strength and stability. At the same time, the opening 42 on the base 1 for the hollow anchor 4 to penetrate provides a channel for the downward detection of the hollow anchor 4.

[0051] After the device is started, the hydraulic rod 3 begins to work. Its drive end is connected to the tail end of the hollow anchor 4. Through the thrust generated by hydraulic transmission, the hollow anchor 4 is driven to be inserted vertically downward into the soil along the opening 42 of the base 1.

[0052] After the hollow anchor 4 reaches the designated position, the micro pump 9 starts and drives the drive rod 8 to move. Since one side of the drive rod 8 slides against the inner wall of the hollow anchor 4, under the limiting action of the hollow anchor 4, the drive rod 8 pushes the travel rod 6, causing the travel rod 6 to produce a horizontal displacement relative to the reference rod 5 (the constraint of the reference rod 5 converts the vertical motion component of the drive rod 8 into the horizontal displacement of the travel rod 6). The travel rod 6 overcomes the elastic force of the return spring 7 in the horizontal direction and extends out of the reference rod 5 (and passes through the detection window 41).

[0053] Since the length of the travel rod 6 penetrating the reference rod 5 is not less than 1 / 3 of the inner diameter of the hollow anchor 4, it ensures that the travel rod 6 can drive the probe 10 to smoothly pass through the detection window 41 on the side wall of the hollow anchor 4 and penetrate deep into the soil, avoiding the deviation of the relative motion angle.

[0054] When the probe 10 comes into contact with the soil, the humidity detector starts to work. The probe 10 senses the humidity information in the soil and converts it into an electrical signal, which is transmitted to the body 61 of the humidity detector through the connected wire for processing and analysis, thereby obtaining soil humidity data.

[0055] After completing the testing task, the micro-pump 9 stops working. The travel rod 6, no longer under external force, retracts into the reference rod 5 in the opposite direction under the elastic force of the return spring 7, causing the probe 10 to withdraw from the soil and return to the hollow anchor 4. Finally, the hydraulic rod 3 restarts, retracting the drive end to pull the hollow anchor 4 upwards from the soil, completing a full soil moisture testing operation.

[0056] In a further preferred embodiment, a slide rail is provided on the inner wall of the hollow anchor 4, and the drive rod 8 is installed inside the slide rail.

[0057] The drive rod 8 is constrained so that it can only slide up and down along the slide rail.

[0058] The design of the sliding rail and drive rod 8 provides relative constraints to address force displacement during device operation. This prevents relative displacement of the structure under stress, which could lead to device failure.

[0059] In a further preferred embodiment, a tilting block is provided on the drive rod 8, and the tilting block is tilted downward.

[0060] The tilting block abuts against the drive end of the travel rod 6, and is used to drive the travel rod 6 to generate horizontal displacement.

[0061] The drive rod 8 slides in contact with the inner wall of the hollow anchor 4. When the micro pump 9 pushes the drive rod 8 downward, the inclined push block of the drive rod 8 presses against the proximal end of the travel rod 6, forcing the travel rod 6 to move horizontally along the guide hole of the reference rod 5.

[0062] The design employs a tilting drive mechanism, resulting in a simple structure.

[0063] In a further preferred embodiment, the hollow anchor 4 has a slot 43 at its tail end; the lead wires of multiple probes 10 pass through the slot 43 and are connected to the body 61 of the humidity detector, which is mounted on the base 1.

[0064] The slot 43 provides a channel for the lead wires of the probe 10 to be led out, and the slot 43 can also provide an installation or signal channel for the signal transmission module of the wireless probe 10.

[0065] The lead wire of probe 10 is sequentially tied and fixed to the travel rod 6 and the reference rod 5, and leads out from the upper end of the reference rod 5, passes through the slot 43, and is connected to the body 61.

[0066] In a further preferred embodiment, the drive circuit of the micro-pump 9 passes through the slot 43 and connects to the control structure 62. The control structure 62 is connected to the body 61 of the humidity detector and multiple hydraulic rods 3.

[0067] The control structure 62 uses a control terminal with a built-in PLC programmable control board. The control structure 62 is equipped with operation ports and data interfaces.

[0068] The drive circuit of the micro pump 9 passes through the slot 43 and connects to the control structure 62, and the control structure 62 is connected to the humidity detector body 61 and multiple hydraulic rods 3.

[0069] The control structure 62 acts as the "central hub," precisely coordinating the working sequence of the micro pump 9, humidity detector, and hydraulic rod 3. For example, after the hydraulic rod 3 drives the hollow anchor 4 to a specified depth, it immediately triggers the micro pump 9 to push the probe 10 for detection. After the detection is completed, it promptly controls the hydraulic rod 3 to retract, ensuring that all components of the device work closely together and operate efficiently, significantly improving the overall work efficiency and continuity.

[0070] Further optimization resulted in the selection of an AIMC-2000 industrial computer for control structure 62.

[0071] In some embodiments, the hollow anchor 4 includes an annular shell, a tunneling tip assembled at the front end of the annular shell, and a load-bearing bottom cover assembled at the rear end of the annular shell. A detection window 41 is provided on the side wall of the annular shell.

[0072] The tunneling tip, reference rod 5, and load-bearing bottom cover are fixedly connected by threads.

[0073] The assembly of the tunneling tip greatly reduces the resistance of the hollow anchor 4 when inserted into the soil, and improves the insertion efficiency.

[0074] The threaded connection facilitates the loading, unloading, and maintenance of the equipment.

[0075] In some embodiments, the base 1 is provided with through holes 11 for mounting ground anchors, and there are multiple through holes 11, which are inclined.

[0076] The ground anchors with multiple inclined through holes 11 are arranged to evenly distribute the external force on the device into the soil, thus avoiding excessive force on a single point of the device.

[0077] When the device is working outdoors, whether facing the reaction force of the soil or the external forces generated by environmental factors such as wind, the inclined ground anchor can form an oblique anchoring force with the soil. This force can effectively counteract the tensile force, thrust and other external forces on the device.

[0078] By dispersing and offsetting external forces, the device can maintain a stable posture and will not easily shift or tip over.

[0079] Compared to the traditional vertical fixing method, the anti-overturning ability is significantly improved.

[0080] In some embodiments, the bottom surface of the base 1 is sequentially coated with a wear-resistant coating, wear marking paint, and anti-corrosion paint. The wear marking paint is red paint, and the thickness of the wear-resistant coating and wear marking paint is not less than 5 mm.

[0081] As the first layer of protection directly in contact with the soil, the wear-resistant coating, with a thickness of no less than 5 mm, effectively resists the friction and scratching of soil particles, significantly reducing the wear rate of the base 1 during long-term use. When the wear-resistant coating gradually wears down to the point where the red wear indicator paint is exposed, maintenance personnel can visually identify the wear condition of the base 1 and perform timely preventative maintenance to avoid structural damage to the base 1 due to excessive wear. The outermost layer of anti-corrosion paint isolates the base 1 from acidic and alkaline substances and moisture in the soil, preventing corrosion of the metal material and further extending its service life.

[0082] In some embodiments, the equipment frame includes a support column 21 disposed on the base 1 and a structural ring 22 connected to the support column 21. Multiple support columns 21 and structural rings 22 are provided. The multiple support columns 21 are arranged in a ring and are fixedly connected to multiple structural rings 22 in sequence. The multiple structural rings 22 are arranged from top to bottom and are fixedly connected to any one of the structural rings 22.

[0083] Multiple ring-shaped pillars 21 and multi-layered structural rings 22 form a stable spatial frame structure.

[0084] When the hydraulic rod 3 drives the hollow anchor 4 to conduct soil detection, the equipment frame can evenly distribute the external forces such as the thrust, tension and vibration generated during the detection process from the hydraulic rod 3 to the base 1 through the ring support 21, and effectively limit the lateral displacement and deformation of the support 21 by utilizing the constraint effect of the multi-layer structure ring 22, thereby enhancing the overall torsional and bending resistance.

[0085] In a further preferred embodiment, the fixed port of the hydraulic rod 3 is fixedly installed at the junction of the structural ring 22 and the support column 21, and no fewer than three hydraulic rods 3 are provided.

[0086] In some embodiments, the hydraulic rod 3 is fixedly connected to the drive end of the hollow anchor 4, and a shower port 51 is provided in the end face of the tail of the hollow anchor 4. The tail end of the shower port 51 passes through the tail of the hollow anchor 4. The shower port 51 and the micro pump 9 are respectively provided on both sides of the reference rod 5.

[0087] As a fulcrum of structural mechanics, the junction point can evenly distribute the thrust and tension generated by the hydraulic rod 3 to the entire equipment frame through the spatial grid structure formed by the structural ring 22 and the support column 21.

[0088] Three or more hydraulic rods 3 are arranged in a ring to evenly distribute the relative forces during the operation of the device.

[0089] To prevent the device from tilting and tilting when subjected to force at a single point, which would cause deviation in the verticality of the soil moisture sampling, this measure is necessary.

[0090] Further optimization involves connecting the shower interface 51 to the water supply pipe.

[0091] The water supply pipeline is used to flush out the soil that enters the hollow anchor 4 during operation, preventing the soil from blocking the unfolding structure and causing the equipment to jam.

[0092] Further optimization involves connecting the shower interface 51 to the water pump and the water storage tank in sequence.

[0093] The water pump and water storage tank are installed on base 1.

[0094] It features a water pump and water tank design, allowing for flushing operations to be performed as needed.

[0095] In a further preferred embodiment, the drive rod 8 is provided with a downwardly inclined push block that engages with the proximal inclined surface of the travel rod 6.

[0096] In a further optimization, the control structure 62 prevents the hydraulic rod 3 from initiating the retraction action before the probe 10 is fully retracted.
