Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, specifically a soil composition testing device. Background Technology

[0002] Soil composition testing equipment is a device used to analyze soil composition. It helps users quickly detect the internal components of soil, rapidly obtain multi-dimensional soil data, and supports rapid detection of parameters such as soil temperature, electrical conductivity, nitrogen, phosphorus, and potassium.

[0003] Existing portable soil composition analyzers include components such as probes and main units. They employ direct-insertion probes and integrate multiple detection technologies, including electrochemical and spectroscopic methods. During use, the probe is directly inserted into the soil to generate test data. To protect the probe's exterior during insertion and reduce direct collisions between the probe tip and hard clumps in the soil, existing technologies typically incorporate a subsurface shuttle on the outside of the probe. This shuttle is installed on the outside of the probe during use and disassembled after testing to clean the probe. This process of disassembling the shuttle, cleaning the probe, and reinstalling the shuttle after each use is cumbersome for repetitive testing.

[0004] To address these issues, we provide soil composition testing equipment. Summary of the Invention

[0005] 1) Technical problems to be solved This invention proposes a soil composition detection device that solves the problem of inconvenient probe use during repetitive testing by coordinating the tension spring, mounting plate, and control ring. Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a soil composition detection device, comprising a main unit and a probe, wherein an installation box is externally connected to the main unit, a fixing frame is fixedly installed on the inner wall of the installation box, a fixing ring is fixedly installed on the inner wall of the fixing frame, and an installation ring is fixedly installed on the outer surface of the fixing ring; A control ring is sleeved on the outer surface of the fixing ring, an installation groove is provided on the inner wall of the mounting ring, a fixing plate is fixedly installed on the inner wall of the installation groove, a fixing shaft is fixedly installed inside the fixing plate, an installation plate is rotatably connected to the outer surface of the fixing shaft, a protective plate is fixedly installed on the outer surface of the mounting plate, and a protective tip is fixedly installed on the outer surface of the protective plate. A connecting plate one is fixedly installed on the lower surface of the mounting box, and a connecting plate two is fixedly installed on the outer surface of the protective plate. A tension spring is installed inside the connecting plate one.

[0007] Furthermore, the probe's mounting base is fixedly installed inside the mounting box, the probe is electrically connected to the host, and the probe's exterior penetrates through the interior of the fixing ring and the mounting ring.

[0008] Furthermore, the outer surface of the mounting ring is provided with external threads, and the inside of the control ring is provided with internal threads. The control ring and the mounting ring are connected by external and internal threads.

[0009] Furthermore, the protective plates are symmetrically arranged on the outside of the probe, with one side of each adjacent protective tip in contact with the other, and adjacent protective plates are connected through the protective tips.

[0010] Furthermore, a liner is fixedly installed on the outer surface of the mounting plate, and the outer surface of the liner is slidably connected to the inner wall of the control ring. When the control ring is connected to the mounting ring, adjacent protective plates are arranged in parallel.

[0011] Furthermore, the tension springs are symmetrically arranged outside the probe, with one end of the tension spring fitted inside the first connecting plate and the other end fitted inside the second connecting plate. The adjacent first and second connecting plates are connected by tension springs.

[0012] (iii) Beneficial effects: Compared with existing technologies, this soil composition testing equipment has the following advantages: I. This soil composition testing equipment, through the cooperation of a tension spring, mounting plate, and control ring, allows the control ring to compress the mounting plate and protective plate when connected to the fixed ring. At this time, the protective plates on both sides can be arranged in parallel, and the two sets of protective plates can close to protect the probe. The probe can then be inserted for testing. After the test is completed, the control ring and mounting ring disengage, and the tension spring can pull the protective plates on both sides to rotate and open, making it convenient for staff to wipe the probe with a cleaning cloth or other items without having to disassemble the probe repeatedly. After cleaning, rotating the control ring reconnects the control ring and mounting ring. When the control ring reconnects, it can reset the protective plate, which can protect the probe again, facilitating the use of the probe during repetitive testing.

[0013] Second, this soil composition testing equipment, by setting up components such as lining plates, can make one side of the mounting plate protrude. At this time, when the control ring rotates, it can stably connect with the mounting plate and reduce the shaking caused by unstable mounting plate. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a soil composition detection device, including a main unit 1 and a probe 2. The main unit 1 is externally connected to a mounting box 3. The mounting base of the probe 2 is fixedly installed inside the mounting box 3. The probe 2 is electrically connected to the main unit 1. The soil composition detector realizes detection through the multi-sensor technology integrated in the probe 2. For example, after the probe 2 is inserted into the soil, it measures the humidity through the FDR frequency domain reflection principle, calculates the water content through the change of electromagnetic wave frequency, and uses the pH electrode to measure the potential difference to obtain the acidity and alkalinity using the electrochemical principle. Then, the data is generated on the main unit 1 through the connection circuit.

[0019] A mounting bracket 4 is fixedly installed on the inner wall of the mounting box 3. A mounting ring 5 is fixedly installed on the inner wall of the mounting bracket 4. A mounting ring 6 is fixedly installed on the outer surface of the mounting ring 5. The probe 2 penetrates the interior of the mounting ring 5 and the mounting ring 6. The probe 2 is installed inside the mounting ring 5 and the mounting ring 6. The mounting bracket 4 is fixed inside the mounting box 3 by fixing bolts.

[0020] The inner wall of the mounting ring 6 has a mounting groove 8, and a fixing plate 9 is fixedly installed on the inner wall of the mounting groove 8. A fixing shaft 10 is fixedly installed inside the fixing plate 9. A mounting plate 11 is rotatably connected to the outer surface of the fixing shaft 10. A protective plate 12 is fixedly installed on the outer surface of the mounting plate 11. A protective tip 13 is fixedly installed on the outer surface of the protective plate 12. The protective plates 12 are symmetrically arranged on the outside of the probe 2. One side of the adjacent protective tips 13 is in contact with each other. The adjacent protective plates 12 are connected through the protective tips 13. The protective tips 13 on both sides can rotate and contact each other. At this time, the protective tips 13 and the protective plates 12 form a protective structure. When the protective plates 12 are closed, they can protect the probe 2. When the probe 2 is inserted, the protective plates 12 and the protective tips 13 first contact the ground. Then the protective plates 12 are rotated. At this time, the loosened soil will enter between the adjacent protective plates 12. At this time, the probe 2 can measure the soil composition by contacting the soil.

[0021] A connecting plate 14 is fixedly installed on the lower surface of the mounting box 3, and a connecting plate 2 15 is fixedly installed on the outer surface of the protective plate 12. A tension spring 16 is installed inside the connecting plate 14. The tension springs 16 are symmetrically arranged outside the probe 2. One end of the tension spring 16 is fitted inside the connecting plate 14, and the other end of the tension spring 16 is fitted inside the connecting plate 2 15. The adjacent connecting plates 14 and 2 15 are connected by the tension spring 16. When the protective plates 12 on both sides are not restricted, the tension spring 16 can control the protective plates 12 to rotate. At this time, the protective plates 12 on both sides can be rotated open, allowing the probe 2 inside to be exposed. At this time, the operator can use a cleaning cloth or other cleaning items to clean the outside of the probe 2. When the protective plates 12 are rotated open, it is also convenient to clean the dirt inside the protective plates 12.

[0022] A control ring 7 is sleeved on the outer surface of the fixing ring 5. The outer surface of the mounting ring 6 is provided with an external thread 17, and the inside of the control ring 7 is provided with an internal thread 18. The control ring 7 and the mounting ring 6 are threadedly connected through the external thread 17 and the internal thread 18. A liner 19 is fixedly installed on the outer surface of the mounting plate 11. The outer surface of the liner 19 is slidably connected to the inner wall of the control ring 7. When the control ring 7 is connected to the mounting ring 6, the adjacent protective plates 12 are arranged in parallel. When the control ring 7 moves above the mounting ring 6, the tension spring 16 pulls the protective plate 12 to rotate and open. When the protective plate 12 is closed, the control ring 7 is rotated to re-thread the control ring 7 and the mounting ring 6. At this time, the control ring 7 can squeeze the protective plate 12 to reset during the downward movement. At this time, the protective plates 12 on both sides can re-contact and close. The liner 19 can protrude one side of the mounting plate 11. At this time, when the control ring 7 rotates, it can stably connect with the mounting plate 11 and reduce the shaking caused by the unstable fixing of the mounting plate 11.

[0023] Working principle: When the control ring 7 is connected to the mounting ring 6, the control ring 7 can squeeze the protective plate 12. At this time, the protective plate 12 closes and can protect the probe 2. During the process of the probe 2 being inserted into the ground, the protective plate 12 and the protective tip 13 can protect the probe 2 and reduce the damage to the probe 2 caused by external stones and other impurities. After a test is completed, the protective plate 12 is pulled out, and the control ring 7 is rotated to disengage the control ring 7 from the mounting ring 6. At this time, the tension spring 16 can pull the protective plate 12 to rotate and open to both sides, and the probe 2 is exposed. The impurities on the probe 2 and the protective plate 12 can be cleaned with cleaning tools. After cleaning, reconnect the control ring 7 to the mounting ring 6. During the movement of the control ring 7, it will squeeze the protective plate 12. At this time, the protective plate 12 will rotate and reset, and re-wrap the probe 2 for protection.
