Description

Technical Field

[0001] This utility model relates to the field of soil monitoring technology, specifically to an intelligent farmland soil nutrient status monitoring instrument. Background Technology

[0002] Soil nutrients are the essential nutrients provided by the soil for plant growth. Nutrients are classified into macronutrients, mesonutrients, and micronutrients. In natural soils, they primarily originate from soil minerals and organic matter, followed by atmospheric precipitation, slope infiltration, and groundwater. In cultivated soils, they also come from fertilization and irrigation. The quality of soil nutrients has a significant impact on crop growth. Complex transformation processes within the soil, soil temperature, and soil moisture all influence the distribution of nutrients, making the monitoring of soil nutrient distribution crucial.

[0003] Traditional soil nutrient monitoring methods require significant manpower and time. Because crop roots grow deep, soil analyzer probes need to be buried deep in the soil to obtain information on nutrient distribution at specific depths. Current methods typically involve workers digging deep holes with shovels to bury the probes, a laborious and time-consuming process. Furthermore, existing nutrient monitoring equipment only detects soil nutrient status without considering the influence of soil moisture and temperature on nutrient distribution, resulting in limited and inaccurate information regarding soil nutrient status. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing an intelligent farmland soil nutrient status monitoring instrument.

[0005] This utility model is achieved through the following technical solution: an intelligent farmland soil nutrient status monitoring instrument, comprising a box and a shell. The shell is fixedly connected to the front outer wall of the box. The box contains a controller, a temperature detector, a humidity detector, and a soil detector. The temperature detector, humidity detector, and soil detector are all electrically connected to the controller, and the probes of the temperature detector, humidity detector, and soil detector are all located outside the box. The shell contains a slider that slides left and right. The middle of the slider has an internally threaded tube. An externally threaded rod is screwed onto the internally threaded tube. The externally threaded rod extends vertically, with a handle fixedly connected to the upper end of the externally threaded rod and a drill bit fixedly connected to the lower end of the externally threaded rod.

[0006] In this design, the externally threaded rod rotates and moves downwards along the internally threaded tube. A drill bit at the bottom of the externally threaded rod drills a hole in the ground to hold the probe. This method is time-saving, labor-saving, and more convenient to use. The slider slides left and right, allowing three holes to be drilled at different locations on the ground. The probes for the temperature detector, humidity detector, and soil detector can be placed into three separate deep holes, enabling simultaneous monitoring of soil temperature, humidity, and nutrient status. This allows personnel to comprehensively assess the soil's temperature and humidity information to make accurate judgments about its nutrient status.

[0007] As an optimization, the enclosure also includes a storage battery. The controller, temperature detector, humidity detector, and soil detector are all electrically connected to the storage battery. A vertically extending adjustment rod is located on the rear outer wall of the enclosure, with a solar panel at the upper end of the rod. The storage battery and the solar panel are electrically connected. This optimized solution uses solar power generation, with the electricity stored in the storage battery, thus saving energy.

[0008] As an optimization, the adjusting rod has multiple pin holes along its length, and a sleeve is fixed to the outer wall of the housing, with pins that mate with the pin holes passing through the sleeve. This optimized design facilitates the assembly and disassembly of the solar panel and allows for adjustment of the solar panel's height.

[0009] As an optimization, a wireless transmission module is also installed inside the housing. The controller is electrically connected to the wireless transmission module, and the wireless transmission module is electrically connected to a battery. This optimized solution transmits the soil information monitored by each probe to the controller, which then transmits the information to the personnel's communication equipment via the wireless transmission module, making it convenient to use.

[0010] As an optimization, the housing is equipped with a nut-screw mechanism for driving the slider to slide. The nut-screw mechanism includes a screw and a guide rod passing through the slider, and a nut. The guide rod extends in the left-right direction and is fixedly connected to the housing. The screw extends in the left-right direction and is rotatably connected to the housing. The nut is threadedly connected to the screw and fixedly connected to the slider. A crank arm is fixedly connected to one end of the screw. In this optimized solution, the slider slides left and right along the screw and guide rod. The guide rod guides the slider's movement, and the crank arm rotates the screw, thereby causing the nut to drive the slider to slide.

[0011] As an optimization, support legs are fixed to the bottom of the box and shell, and these support legs are connected to the ground by nails. This optimization improves the stability of the device.

[0012] The beneficial effects of this invention are as follows: The externally threaded rod rotates and moves downward along the internally threaded tube, drilling a hole in the ground through the drill bit at the bottom of the externally threaded rod to place the probe. This method saves time and effort and is more convenient to use. The slider slides left and right, thus drilling three holes at different locations on the ground. The probes of the temperature detector, humidity detector, and soil detector can be placed into three deep holes respectively, allowing simultaneous monitoring of soil temperature, humidity, and nutrient status. This is more intelligent and facilitates accurate judgment and understanding of soil nutrient status by comprehensively considering soil temperature and humidity information.

[0021] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0022] like Figures 1-6 As shown, an intelligent farmland soil nutrient status monitoring instrument includes a box 1 and a shell 2. The shell 2 is fixed to the front outer wall of the box 1. Multiple support legs 9 are fixed to the bottom of the box 1 and the shell 2. The support legs 9 are connected to the ground by iron nails 10.

[0023] The housing 1 houses a controller 8, a temperature detector 5, a humidity detector 6, and a soil detector 7. All three detectors are electrically connected to the controller 8, and their probes 21 are located outside the housing 1. In this embodiment, the temperature detector 5, humidity detector 6, and soil detector 7 are connected to their respective probes 21 via wires 20. A wire-passing hole is provided on the side wall of the housing 1 for the wires 20 to pass through.

[0024] The enclosure 1 is also equipped with a storage battery 3, and the controller, temperature detector, humidity detector and soil detector are all electrically connected to the storage battery 3.

[0025] The housing 1 is also equipped with a wireless transmission module 4. The controller 8 is electrically connected to the wireless transmission module 4, and the wireless transmission module 4 is electrically connected to the battery 3.

[0026] A vertically extending adjusting rod 23 is provided on the rear outer wall of the housing 1. A solar panel 26 is provided at the upper end of the adjusting rod 23, and the battery 3 is electrically connected to the solar panel 26. Specifically, the adjusting rod 23 has multiple pin holes 24 along its length, and a sleeve 22 is fixedly connected to the outer wall of the housing 1. A pin 25 that mates with the pin holes 24 passes through the sleeve 22.

[0027] The solar panel 26 generates electricity and stores it in the battery 3. The battery 3 then powers the controller 8, temperature detector 5, humidity detector 6, soil detector 7, and wireless transmission module 4, thus saving energy.

[0028] Specifically, the housing 1 has three layers of partitions arranged from top to bottom, dividing the interior of the housing 1 into a first cavity, a second cavity, a third cavity, and a fourth cavity. The battery 3 is fixedly installed in the first cavity, the wireless transmission module 4 is fixedly installed in the second cavity, the temperature detector 5, the humidity detector 6, and the soil detector 7 are all fixedly installed in the third cavity, and the controller 8 is fixedly installed in the fourth cavity. The four cavities separate the components, facilitating distributed heat dissipation. Furthermore, each cavity has heat dissipation holes 27 on its sidewalls to further improve heat dissipation.

[0029] The housing 2 contains a slider 11 that slides horizontally. An internally threaded tube 12 is located in the middle of the slider 11, penetrating vertically through it and fixedly connected to the slider 11. An externally threaded rod 13 is screwed onto the internally threaded tube 12, extending vertically. A handle 14 is fixedly attached to the upper end of the externally threaded rod 13, and a drill bit 15 is fixedly attached to its lower end. In this embodiment, the top and bottom of the housing 2 have through holes for the externally threaded rod 13 to pass through, extending horizontally to facilitate its left-right movement.

[0030] Specifically, the housing 2 is equipped with a nut and screw mechanism for driving the slider 11 to slide. The nut and screw mechanism includes a screw 16 and a guide rod 17 passing through the slider 11, and a nut 18. The guide rod 17 and the screw 16 are arranged in parallel. The guide rod 17 extends in the left-right direction and is fixedly connected to the housing 2. The screw 16 extends in the left-right direction and is rotatably connected to the housing 2. The nut 18 is threadedly connected to the screw 16 and fixedly connected to the slider 11. A crank arm 19 is fixedly connected to one end of the screw 16. In this embodiment, both ends of the screw are rotatably connected to the two sides of the housing through bearings.

[0031] Working principle: The operator rotates handle 14 to rotate the external threaded rod 13, which moves downwards along the internal threaded tube 12, causing the drill bit 15 at the bottom to drill into the soil. The operator rotates crank arm 19 to rotate lead screw 16, which in turn drives slider 11 to slide left and right via threaded nut 18. In this way, slider 11 slides left and right, creating three deep holes in the ground for placing probes 21. Since the probes 21 of temperature detector 5, humidity detector 6, and soil detector 7 extend to the outside of housing 1 via wires 20, the operator places the three probes 21 into the three deep holes respectively, thereby monitoring the temperature, humidity, and nutrient status deep within the soil. Temperature detector 5, humidity detector 6, and soil detector 7 transmit the monitoring data to controller 8, which then wirelessly transmits the data to the operator's communication device via wireless transmission module 4, facilitating real-time monitoring and ease of use.
