Description

Technical Field

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

[0002] Soil testing is crucial in many fields, including agricultural production, geological exploration, and ecological environment research. As a key tool for obtaining various soil parameters, the performance and ease of use of soil testing instruments directly impact the efficiency and accuracy of the testing process.

[0003] In traditional soil testing instruments, the testing probe, as the component in direct contact with the soil, is susceptible to contamination and damage from the external environment when not in use. For example, during storage, dust and moisture may adhere to the surface of the probe, affecting its testing accuracy; during transport, the probe may also collide or rub against other objects, causing damage to its physical structure. Moreover, once the probe becomes contaminated with soil or other impurities, it will interfere with subsequent test results, requiring additional time and effort for cleaning and calibration. On the other hand, the instrument's display screen and operating buttons are crucial human-machine interfaces, directly affecting the user's ability to accurately obtain test data and operate the instrument. However, traditional testing instruments often lack effective protective measures; the display screen is easily scratched and worn, and the operating buttons may malfunction due to accidental touches or moisture. Especially in complex outdoor working environments, such as dusty weather or rainy days, the display screen and operating buttons are more easily damaged, affecting the normal use of the instrument.

[0004] Therefore, it is necessary to provide a soil testing instrument to solve the above-mentioned technical problems. Utility Model Content

A second compression spring is sleeved on the surface of the movable rod. The two ends of the second compression spring are fixedly connected to the surfaces of the plug rod and the fixed seat, respectively.

[0008] As a preferred embodiment of this utility model, a threaded hole is provided on one side of the upper part of the movable cover, and a knob bolt is threadedly connected inside the threaded hole. An elastic pad that cooperates with the knob bolt is fixedly connected to one side of the fixed shell.

[0009] As a preferred embodiment of this utility model, T-shaped strips are fixedly connected to both sides of the inner wall of the movable cover, and T-shaped grooves that cooperate with the T-shaped strips are opened on both sides of the fixed shell, and the surface of the T-shaped strips is slidably connected to the inner wall of the T-shaped grooves.

[0010] As a preferred embodiment of this utility model, the surface of the protective cover is provided with an observation port corresponding to the display screen, and a transparent glass plate is fixedly connected inside the observation port.

[0011] In a preferred embodiment of this invention, the inner diameter of the rubber scraper ring is the same as the diameter of the detection probe, and the inner surface of the rubber scraper ring slides in contact with the surface of the detection probe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1.

[0016] 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.

[0017] like Figures 1 to 6 As shown, the soil testing instrument provided by this utility model includes a testing instrument body 1. A groove is formed on the front of the testing instrument body 1, with a display screen 2 positioned above the groove and an operation button 3 positioned below the groove. Hollow rods 4 are fixedly connected to both sides of the bottom of the testing instrument body 1. A detection probe 5 is fixedly connected to the bottom end of the hollow rod 4. A wire is installed inside the hollow rod 4, and the detection probe 5 is electrically connected to the testing instrument body 1 via the wire. A fixing shell 6, sleeved on the surface of the hollow rod 4, is fixedly connected to the bottom of the testing instrument body 1. The surface of the fixing shell 6... A movable cover 7 is slidably connected to the top and bottom of the movable cover 7. A bottom plate 8 is fixedly connected to the bottom of the movable cover 7. Circular grooves are opened on both sides of the bottom plate 8. Replaceable rubber scraper rings 9 are fixedly connected to the inside of the circular grooves by bolts. A first compression spring 10 is sleeved on the surface of the hollow rod 4. The top end of the first compression spring 10 is fixedly connected to the bottom of the detector body 1, and the bottom end of the first compression spring 10 is fixedly connected to the top of the bottom plate 8. A protective cover plate 11 located on the surface of the display screen 2 and the operation button 3 is hinged inside the groove. A locking mechanism 12 is provided on the top of the detector body 1.

[0018] refer to Figure 6 The locking mechanism 12 includes a lock seat 13 fixedly connected to the top of the protective cover plate 11 and a fixed seat 14 fixedly connected to the top of the detector body 1. A moving rod 15 is slidably connected inside the fixed seat 14. One end of the moving rod 15 is fixedly connected to an insertion rod 16. The bottom of the insertion rod 16 is slidably connected to the top of the detector body 1. The end of the insertion rod 16 away from the moving rod 15 is in contact with the inner wall of the lock seat 13. A second compression spring 17 is sleeved on the surface of the moving rod 15. The two ends of the second compression spring 17 are fixedly connected to the surfaces of the insertion rod 16 and the fixed seat 14, respectively.

[0019] As a technical optimization of this utility model, the cooperation of the locking seat 13 and the fixed seat 14, along with the setting of the moving rod 15, the insert rod 16, and the second compression spring 17, allows the protective cover 11 to be securely closed on the main body 1 of the detector. When the protective cover 11 is closed, the insert rod 16 is inserted into the locking seat 13 under the action of the second compression spring 17, preventing the protective cover 11 from being opened accidentally, thereby effectively protecting the display screen 2 and the operation button 3. When it is necessary to open the protective cover 11, simply overcome the elastic force of the second compression spring 17 to move the moving rod 15, causing the insert rod 16 to disengage from the locking seat 13. The operation is simple and convenient, which not only enhances the stability of the protective cover 11 but also improves the overall safety and reliability of the instrument, ensuring that the display screen 2 and the operation button 3 are well protected when used in various environments.

[0020] refer to Figure 2 A threaded hole is provided on one side of the upper part of the movable cover 7, and a knob bolt 18 is connected to the internal thread of the threaded hole. An elastic pad 19 that works with the knob bolt 18 is fixedly connected to one side of the fixed cover 6.

[0021] As a technical optimization of this utility model, the threaded hole and knob bolt 18 on the movable cover 7, along with the elastic pad 19 on the fixed cover 6, cooperate to facilitate the fixation of the movable cover 7. Users can rotate the knob bolt 18 to make it tightly contact the elastic pad 19, utilizing the elastic deformation of the elastic pad 19 to generate friction, thereby fixing the movable cover 7 at a specific position on the fixed cover 6. This ensures the movable cover 7 remains stable under different working conditions. For example, when the detection probe 5 is inserted into the soil, the movable cover 7 can be slid upwards and fixed to prevent it from affecting the detection operation; when not in use, the movable cover 7 can be slid downwards and fixed to protect the detection probe 5.

[0022] refer to Figure 2 and Figure 4 Both sides of the inner wall of the movable cover 7 are fixedly connected with T-shaped strips 20, and both sides of the fixed cover 6 are provided with T-shaped grooves 21 that cooperate with the T-shaped strips 20. The surface of the T-shaped strips 20 is slidably connected to the inner wall of the T-shaped grooves 21.

[0023] As a technical optimization of this utility model, by setting the T-shaped strip 20 on the inner wall of the movable cover 7 to cooperate with the T-shaped grooves 21 on both sides of the fixed shell 6, a stable guiding effect is provided for the up-and-down sliding of the movable cover 7. This ensures that the movable cover 7 will not deviate or shake during the sliding process, guaranteeing its smoothness and accuracy of movement, improving the ease of operation of the movable cover 7, and enhancing the overall stability of the instrument. At the same time, the cooperation of the T-shaped strip 20 and the T-shaped grooves 21 also prevents the movable cover 7 from falling off the fixed shell 6, further improving the safety and reliability of the instrument.

[0024] refer to Figure 1 The protective cover 11 has an observation port 22 corresponding to the display screen 2 on its surface, and a transparent glass plate is fixedly connected inside the observation port 22 by sealant.

[0025] As a technical optimization of this utility model, the observation port 22 opened on the surface of the protective cover 11 and the transparent glass plate inside protect the display screen 2 while facilitating the user's viewing of test data. The user can clearly observe the information on the display screen 2 through the transparent glass plate without opening the protective cover 11, improving operational convenience. The transparent glass plate is fixed inside the observation port 22 with sealant, providing excellent sealing and preventing dust, moisture, etc., from entering the interior of the protective cover 11, further protecting the display screen 2. This satisfies the protection requirements for the display screen 2 without affecting the user's acquisition of test data, making the instrument more efficient and practical during use.

[0026] refer to Figure 4 The inner diameter of the rubber scraper ring 9 is the same as the diameter of the detection probe 5, and the inner surface of the rubber scraper ring 9 slides in contact with the surface of the detection probe 5.

[0027] As a technical optimization of this utility model, by setting the inner diameter of the rubber scraper ring 9 to be the same as the diameter of the detection probe 5, and the inner surface of the rubber scraper ring 9 to slide in contact with the detection probe 5, the rubber scraper ring 9 can effectively scrape off the soil adhering to its surface when the detection probe 5 is pulled out of the soil. The replaceable rubber scraper ring 9 design allows users to replace it in a timely manner when it is worn or damaged, ensuring the continuity of the cleaning effect. By scraping off the soil on the surface of the detection probe 5, corrosion and damage to the detection probe 5 by soil can be avoided, extending its service life. At the same time, it can also ensure the accuracy of the detection probe 5 in the next test and reduce the detection error caused by soil residue.

[0028] The working principle and usage process of this utility model are as follows: When not in use, the protective cover 11 is tightly closed by the locking mechanism 12, which protects the display screen 2 and the operation button 3 from external collisions, dust and moisture corrosion; the movable cover 7 is in the lower position under the action of the first compression spring 10, and the rubber scraper ring 9 on the bottom plate 8 is fitted on the detection probe 5 to prevent the detection probe 5 from being contaminated and damaged. When soil testing is required, the locking mechanism 12 is operated first to overcome the elastic force of the second compression spring 17 to move the moving rod 15 so that the insertion rod 16 is disengaged from the locking seat 13 and the protective cover 11 is opened. Next, slide the movable cover 7 upwards to make the rotating knob bolt 18 contact the elastic pad 19 tightly, fixing the movable cover 7 in a suitable position and exposing the detection probe 5. Then, insert the detection probe 5 at the bottom of the detector body 1 directly into the soil. The detection probe 5 senses various parameters of the soil and transmits the signal to the detector body 1 through the wire in the hollow rod 4 (the detector body 1 is a common insertion-type soil detector, and its working principle is a mature existing technology, so it will not be described in detail). The display screen 2 displays the detection data in real time. The user can perform related operations and settings through the operation button 3. After the test is completed, pull out the detection probe 5. During the pulling process, the rubber scraper ring 9 will automatically scrape off the soil attached to the surface of the detection probe 5. Afterwards, loosen the knob bolt 18, and the movable cover 7 will automatically reset under the action of the first compression spring 10, close the protective cover 11 and lock it through the locking mechanism 12, so that the detector returns to the unused state and is ready for the next test.
