Description

Technical Field

[0001] This utility model relates to the field of soil testing, specifically a device for detecting the nutrient content of rice soil. Background Technology

[0002] Soil testing refers to the scientific process of quantitatively or qualitatively analyzing various properties of soil samples through physical, chemical, or biological methods to assess their fertility, environmental quality, and health. In the detection of nutrient content in paddy soil, a soil rapid tester and soil sensor are used together.

[0003] After a soil sensor is inserted into the soil for detection, the surface of the insertion end will be covered with soil. Usually, it is wiped directly with a tool or cloth. This can easily scratch the ion-selective membrane, glass membrane or biological coating of the sensor head, causing permanent and irreversible damage, thereby reducing the lifespan of the sensor. Utility Model Content

[0004] To address the shortcomings of existing technologies, after a soil sensor is inserted into the soil for detection, the surface of the insertion end becomes covered with soil. This is usually wiped directly with a tool or cloth, which can easily scratch the ion-selective membrane, glass membrane, or biological coating on the sensor head, causing permanent and irreversible damage and reducing the lifespan of the sensor. This invention proposes a device for detecting the nutrient content of rice soil.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a rice soil nutrient element content detection device, including a soil sensor, a connecting wire fixedly connected to the surface of the soil sensor, a sensing rod fixedly connected to the surface of the soil sensor, the number of the sensing rods being four, and a scraping mechanism and a protective mechanism being provided on the surface of the soil sensor. The scraping mechanism includes a movable plate, the inner cavity of which is movably connected to the surface of a sensing rod. Four rubber sleeves are fixedly connected to the inner cavity of the movable plate, with the inner side of each sleeve in close contact with the surface of a sensing rod. Two connecting blocks are fixedly connected to the surface of the movable plate, and a movable plate is fixedly connected to the surface of each connecting block. The surface of the movable plate is movably connected to the surface of a soil sensor. A sliding block is fixedly connected to the inner side of each movable plate, and the surface of the sliding block is movably connected to the inner cavity of the soil sensor.

[0006] Preferably, the surface of the soil sensor is provided with two sliding grooves, and the inner cavity of each sliding groove is movably connected to the surface of a sliding block.

[0007] Preferably, a limiting block is fixedly connected to the inner cavity of each sliding groove, and the shape of the limiting block is consistent with the shape of the sliding block.

[0008] Preferably, a spring is fixedly connected to the surface of each sliding block, and one end of the spring is fixedly connected to the surface of the limiting block.

[0009] Preferably, each of the movable plates has an anti-slip pad fixedly connected to its surface, and the anti-slip pad is made of rubber.

[0010] Preferably, the protective mechanism includes two protective plates, and a connecting frame is fixedly connected to the surface of both protective plates. The inner cavity of the protective plate is movably connected to the surface of the soil sensor and the movable plate.

[0011] Preferably, the surface of the soil sensor is provided with a movable groove, and there are two movable grooves. The inner cavity of each movable groove is movably connected with a threaded rod. The surface of the threaded rod is threadedly connected to the inner cavity of the protective plate, and a rotating block is fixedly connected to one end of the threaded rod.

[0012] The advantages of this utility model are: This invention utilizes a soil sensor, connecting wire, sensing rod, scraping mechanism, and protective mechanism in conjunction. When there is soil on the surface of the sensing rod, the scraping mechanism first removes the soil, followed by rinsing with clean water. This avoids the problem of hard objects in the soil repeatedly rubbing against the surface of the sensing rod when wiping it with a cloth, which can scratch the coating. When the sensing rod is not in use, the protective mechanism protects it from impact damage. This solves the problem that after the soil sensor is inserted into the soil, the surface of the insertion end becomes covered with soil, which is usually wiped directly with a tool or cloth. This can easily scratch the ion-selective membrane, glass membrane, or biological coating of the sensor head, causing permanent and irreversible damage and reducing the lifespan of the sensor.

[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 scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses a device for detecting the nutrient element content in rice soil. (Refer to...) Figure 1 and Figure 4 A device for detecting the nutrient content of rice soil includes a soil sensor 1, a connecting wire 2 fixedly connected to the surface of the soil sensor 1, a sensing rod 3 fixedly connected to the surface of the soil sensor 1, and four sensing rods 3. The surface of the soil sensor 1 is provided with a scraping mechanism 4 and a protective mechanism 5. The scraping mechanism 4 includes a movable plate 403, the inner cavity of which is movably connected to the surface of the sensing rod 3. A rubber sleeve 405 is fixedly connected to the inner cavity of the movable plate 403. There are four rubber sleeves 405, and the inner side of each rubber sleeve 405 is in close contact with the surface of a sensing rod 3. A connecting block 404 is fixedly connected to the surface of the movable plate 403. There are two connecting blocks 404. A movable plate 401 is fixedly connected to the surface of each connecting block 404. The surface of the movable plate 401 is movably connected to the surface of the soil sensor 1. A sliding block 408 is fixedly connected to the inner side of each movable plate 401. The surface of the sliding block 408 is movably connected to the inner cavity of the soil sensor 1.

[0018] Reference Figure 4The surface of the soil sensor 1 is provided with a sliding groove 406. There are two sliding grooves 406. The inner cavity of each sliding groove 406 is movably connected to the surface of a sliding block 408. The sliding grooves 406 guide the sliding block 408 to slide in the inner cavity of the soil sensor 1, thereby indirectly improving the stability of the movable plate 401 sliding on the surface of the soil sensor 1. Reference Figure 4 Each sliding groove 406 has a fixed limit block 409 in its inner cavity. The shape of the limit block 409 is the same as that of the sliding block 408. The limit block 409 provides support for one end of the spring 407 and limits the sliding block 408, preventing the sliding block 408 from sliding out of the inner cavity of the sliding groove 406. Reference Figure 4 Each sliding block 408 has a spring 407 fixedly connected to its surface. One end of the spring 407 is fixedly connected to the surface of the limiting block 409. Through the setting of the spring 407, its elasticity will make the sliding block 408 always on one side of the sliding groove 406 without the influence of external force. This indirectly causes the moving plate 403 to move to the right under force to clean the surface of the sensing rod 3. When the force is released, the elasticity of the spring 407 will push the sliding block 408, indirectly causing the moving plate 403 to slide back to the initial position, thus playing a resetting role. Reference Figure 4 Each movable plate 401 has an anti-slip pad 402 fixedly connected to its surface. The anti-slip pad 402 is made of rubber. The anti-slip pad 402 is designed to prevent slipping when the staff pushes the movable plate 401. Reference Figure 1 and Figure 2 The protective mechanism 5 includes two protective plates 501. The surfaces of the two protective plates 501 are fixedly connected to a connecting frame 502. The inner cavity of the protective plate 501 is movably connected to the surface of the soil sensor 1 and the movable plate 401. The protective plate 501 and the connecting frame 502 are used to protect the sensor rod 3 when the protective plate 501 covers the sensor rod 3. When the sensor rod 3 needs to be used, the protective plate 501 can be slid to the left side for storage. Reference Figure 3The surface of the soil sensor 1 is provided with two movable grooves 505. Each movable groove 505 has a threaded rod 504 movably connected to its inner cavity. The surface of the threaded rod 504 is threadedly connected to the inner cavity of the protective plate 501. One end of the threaded rod 504 is fixedly connected to a rotating block 503. With the rotating block 503, threaded rod 504 and movable groove 505 configured, rotating the rotating block 503 causes the threaded rod 504 to rotate threadedly in the inner cavity of the protective plate 501 and move, so that one end of the threaded rod 504 is in close contact with the inner cavity of the movable groove 505, thereby fixing the position of the protective plate 501. When the rotating block 503 is rotated in the opposite direction, the surface of the threaded rod 504 is disengaged from the close contact with the inner cavity of the movable groove 505, which can pull the protective plate 501 to slide and drive the threaded rod 504 to slide in the inner cavity of the movable groove 505, thus preventing the protective plate 501 from detaching from the surface of the soil sensor 1.

[0019] Working principle: When it is necessary to test the nutrient elements of paddy soil, the connecting wire 2 is inserted into the soil rapid tester, and then the sensor rod 3 is inserted into the soil. Through the sensing detection of the sensor rod 3, the final data will be displayed on the screen of the soil rapid tester. The above is the existing technology and will not be elaborated further. Before use, the sensor rod 3 is protected by the protective mechanism 5. Therefore, it is necessary to rotate the rotating block 503. The rotating block 503 drives the threaded rod 504 to rotate in the inner cavity of the protective plate 501 and move until the threaded rod 504 rotates. One end of 4 disengages from the tight contact with the inner cavity of the moving groove 505 in the soil sensor 1. At this time, the sliding protective plate 501 is slidable, exposing the sensor rod 3. When the protective plate 501 slides to the appropriate position, the rotating block 503 rotates in the opposite direction, indirectly causing the threaded rod 504 to make tight contact with the inner cavity of the moving groove 505, thereby fixing the position of the protective plate 501. At this time, the sensor rod 3 can be normally inserted into the soil for detection. When the detection is completed and it is pulled out of the soil, its surface will be covered with soil. At this time, the anti-slip pad 402 is pushed, and the anti-slip pad... 402 drives the movable plate 401 to move, which in turn moves the sliding block 408 into the inner cavity of the sliding groove 406 in the soil sensor 1. Simultaneously, it pushes the spring 407 to compress and deform, which in turn drives the connecting block 404 to move. The connecting block 404 then moves the movable plate 403 to the surface of the sensing rod 3. The rubber sleeve 405 inside the movable plate 403 can scrape off the soil from the surface of the sensing rod 3 beforehand, reducing the risk of hard objects in the soil scratching the coating on the surface of the sensing rod 3 during the cleaning process. Next, the rubber sleeve 405 and the sensor rod 3 are rinsed with water. Then, the pushing force on the anti-slip pad 402 is released. Due to the elastic pushing force of the spring 407, the sliding block 408 will be pushed to the initial position, which indirectly causes the moving plate 403 to return to the initial position. When the sensor rod 3 is not in use, the rotating block 503 is rotated, which indirectly causes the protective plate 501 to lose its fixation. Then, the protective plate 501 is slid to cover the sensor rod 3. Then, the rotating block 503 is rotated in the opposite direction to fix the protective plate 501, protecting the sensor rod 3 from damage caused by accidental impact.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
