Abstract
Description
Technical area
[0001] The present utility model relates to the field of soil nutrient detection technology, in particular to a soil nutrient detector for digital agriculture. Technology in the background
[0002] Digital agriculture refers to the integration of advanced technologies such as remote sensing, geographic information systems, global positioning systems, computer technology, communication and networking, and automation with fundamental disciplines such as geography, agronomy, ecology, plant physiology, and soil science. This enables real-time monitoring of plants and soils at the macro and micro levels throughout agricultural production. It facilitates the regular collection of information on plant growth, developmental stage, pest and disease infestation, water and fertilizer status, and related environmental factors.The creation of dynamic spatial information systems and the simulation of phenomena and processes in agricultural production are intended to achieve rational use of agricultural resources, a reduction in production costs, an improvement in the ecological environment, and an increase in crop yield and quality.
[0003] As disclosed in utility model CN216900534U, a novel soil nutrient detector comprises a base plate and a detection cylinder. Four support columns are attached to each corner of the base of the base plate, each with rollers at its base. A fastening device is provided at the base of one side of each support column. The main body of the soil nutrient tester is attached to the top of the base plate. A cylinder cover is attached to the top of the detection cylinder and is pivotally connected to a threaded rod via a bearing in its center. A sliding disc is slidably mounted inside the detection cylinder.The advantageous effects of this utility model are as follows: The detection cylinder can be separated from the support plate, eliminating the need to reposition the main body of the soil nutrient detector at different locations when examining soil samples, thus increasing practicality; the provision of a rotating wheel facilitates the rotation of the connecting screw, which in turn drives the movable disc to a linear movement, thereby moving the metal probe up and down to examine soil samples at different depths.
[0004] The measuring device described in this utility model must be inserted into the ground for measurement. When the lower metal probe is withdrawn after the measurement, its outer surface becomes covered with soil. This necessitates manual cleaning of the probe, as otherwise the accuracy of subsequent measurements will be compromised. Manual cleaning is both time-consuming and labor-intensive, yet it cannot completely remove all soil and residue from the probe. Consequently, subsequent tests yield results with inherent inaccuracies, which impairs the effectiveness of the nutrient analyzer. Content of the utility model
[0005] The present utility model aims to solve the aforementioned problems by providing a soil nutrient detector for digital agriculture.
[0006] The technical solution chosen for the present utility model is as follows: A soil nutrient detector for digital agriculture comprises a worktable on the top of which a water tank is mounted. A water supply line is connected to a side surface of the water tank, with a water pump attached to the outer surface of the water supply line. An annular spray tube is fixedly connected to an end surface of the water supply line. A spray channel is formed on the underside of the annular spray tube. A bracket is provided on the inner wall surface of the spray channel. A connecting rod is attached to the outer surface of the bracket. A scraper is fixedly attached to the outer surface of the connecting rod. A cleaning brush is attached to the inner surface of the scraper.
[0007] The aforementioned technical solution enables more stable operation of the device positioned above it by installing the workbench. The installed water tank supplies the circular spray nozzle below with water, thus facilitating the rinsing of the metal probe's surface. The installed water supply line and pump facilitate the transfer of water from the tank through the supply line to the annular spray line. This allows the clean water to be directed into the interior of the lower channel within the annular spray line, thereby rinsing the outer surface of the metal probe. Furthermore, the cleaning effect is enhanced when used with cleaning brushes, ensuring the thorough removal of dirt and contaminants from the metal probe. This guarantees the accuracy of subsequent detection processes, thus ensuring both stability and precision.The integrated channel not only facilitates the passage of the metal probe through the channel walls to make contact with the soil, but also enables more stable and convenient operation of the internal cleaning mechanism. The bracket secures the external cleaning device within the channel, while the connecting rod ensures a stable connection between the cleaning device and the bracket. The integrated scraper effectively removes soil from the surface of the metal probe. As the second cylinder extends or retracts the metal probe, the scraper simultaneously cleans the surface, reducing the need for manual cleaning. The cleaning brush, integrated into the circular spray nozzle, cleans the surface of the metal probe. This water-assisted cleaning method enhances the cleaning performance of the metal probe, ensuring adaptability and thorough cleanliness.
[0008] In a preferred embodiment, the underside of the workbench is rigidly connected to several support columns. The underside of these columns is equipped with swivel casters, while the outer surface of the columns is slidably connected to a limiting ring.
[0009] The aforementioned technical solution, with its four fixed columns mounted beneath the workbench surface, ensures greater stability of the device during operation. The installed casters reduce the weight of the nutrient analyzer while allowing for smoother movement. Positioning rings enable vertical sliding along the fixed columns, further improving both stability and practicality.
[0010] In a preferred embodiment, a lifting plate is fixedly attached to the inner surface of the boundary ring. A first cylinder is provided below the workbench surface, its base being fixedly connected to the lifting plate. The lifting plate is slidably connected to the boundary ring.
[0011] By employing the aforementioned technical solution, the installed first cylinder drives the underlying telescopic column for extension and retraction. This allows for height adjustment of the lifting plate's vertical movement, which in turn actuates the fixed mechanisms on both sides for raising and lowering. Lowering the fixed mechanisms secures the device and increases stability during inspection. When the fixed mechanisms are not in use, the lifting plate can be retracted inwards, ensuring comprehensive functionality and versatility.
[0012] In a preferred embodiment, support legs are attached to the top of the workbench, with a nutrient analyzer positioned on the top of the support legs. A second cylinder is attached to the underside of the nutrient analyzer.
[0013] By employing the aforementioned technical solution, the installed support legs bear the weight of the nutrient detector located above, thereby improving its operational stability. The installed nutrient detector enables the detection of soil nutrients in digital agriculture. The installed second cylinder facilitates the extension and retraction of the detection cylinder below, driving the contraction of the detection device at its base, thus ensuring stability and adaptability.
[0014] In a preferred embodiment, the lower outlet end of the second cylinder is fixedly connected to the detection cylinder, while the underside of the nutrient detector is provided with connecting wires.
[0015] By using the aforementioned technical solution, the installed connecting wires enable the transmission of soil nutrients detected by the lower detection device to the nutrient analyzer. This facilitates the nutrient analyzer's evaluation of the soil nutrient content detected by the device. The installed detection cylinder ensures a more stable connection between the nutrient analyzer and the lower detection device, thus improving its practicality and detection capabilities.
[0016] In a preferred embodiment, the underside of the detection cylinder is connected to a probe needle. The upper side of the probe needle is provided with a metal probe head, while its outer surface is equipped with spiral blades. The metal probe head has a conical shape.
[0017] By employing the aforementioned technical solution, the installed metal probe overcomes the problem of the soil being too hard for detection. The configured spiral blades allow for gentler penetration of the detection device into the soil during inspection, thereby reducing resistance and ensuring both fluidity and completeness of the soil investigation.
[0018] In a preferred embodiment, a power supply unit is mounted on the top of the workbench. A side panel is attached to the outer surface of one end of the workbench, and a push rod is mounted to the inner surface of this side panel. A non-slip sleeve is fitted over the outer surface of the push rod.
[0019] The aforementioned technical solution allows for more stable operation of the internal push rod by installing side panels. The mounted push rod provides a secure grip for personnel to operate the device. The attached non-slip sleeve effectively prevents slippage during operation, ensuring a firm hold on the smooth surface of the push rod and thus increasing stability when maneuvering the device. The integrated power supply provides electricity to the nutrient analyzer, ensuring both stability and compatibility.
[0020] In a preferred embodiment, the outer surface of the limiting ring is fixedly connected to a mounting block. The central part of the mounting block has a threaded bushing, the inner surface of which is screwed to a threaded rod. The underside of the threaded rod is provided with a drill bit, while its upper side has a non-slip rotating disc.
[0021] By using the aforementioned technical solution, rotating the non-slip turntable sets the threaded rod in motion. This allows the threaded rod to slide downwards through its threaded connection with the threaded bushing, enabling the drill bit to penetrate the ground and secure its position. This ensures both versatility and stability.
[0022] In summary, the advantageous effects of the present utility model, achieved through the above-mentioned technical solution, can be described as follows: 1. The integrated cleaning brushes remove dirt and soil from the surface of the metal probe at the bottom of the detection cylinder during its vertical movement. Furthermore, these brushes can be combined with the rinsing device to rinse the cleaned metal probe, achieving a double cleaning process. This two-stage cleaning process increases cleaning efficiency and ultimately improves overall cleaning performance. 2. By switching between the mobile mechanism and the sliding mechanism, the fixed mechanism can be used to fix the position of the device during the soil investigation. After completion of the investigation, the position of the device can be changed using the casters by retracting the fixed mechanism. 3. The second pneumatic cylinder drives the extension and retraction of the detection cylinder, allowing the underlying metal probe to move vertically. This facilitates testing at different soil depths. Additionally, the integrated power supply provides the nutrient analyzer with electricity, ensuring that the device functions properly during field soil testing.
