Description

Technical Field

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

[0002] Soil environmental monitoring refers to determining environmental quality and its changing trends by measuring representative values ​​of factors affecting soil environmental quality. Preliminary assessments are typically made based on soil pH values, thus requiring the use of soil pH testing devices. However, an existing soil pH testing device (announcement number: CN215005112U) has the following drawbacks in use:

[0003] In its use, when the soil is hard, the soil is sent into the sampling tube and then analyzed and detected by the probe. However, for hard soil, the user needs to carry other devices for sampling and testing, which increases the burden and is inconvenient. Therefore, this patent proposes a soil pH detection device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a soil pH testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soil pH testing device, comprising a connecting shell, a fixing plate rotatably connected between the inner walls of both sides of the connecting shell, a gear ring rotatably connected to the top of the fixing plate, a gear rotatably connected to the top of the fixing plate, the gear meshing with the gear ring, a motor fixed to the bottom of the fixing plate, the output end of the motor passing through the fixing plate and fixed to the bottom of the gear, a rotating sleeve fixed to the bottom of the gear ring, the rotating sleeve passing through the bottom of the fixing plate and the connecting shell, a drill bit fixed to the outer wall of the rotating sleeve below the connecting shell, a fixing shell fixed to the top of the connecting shell, an insertion rod inserted through the top of the fixing shell, the bottom end of the insertion rod passing through the connecting shell, a probe fixed to the bottom end of the insertion rod, a connection port being opened through the top of the drill bit, and the probe being located inside the connection port.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The difference between this soil pH testing device and existing technologies is that when testing harder soil is required, a motor drives a gear to rotate, which in turn drives a gear ring to rotate, which in turn drives a rotating sleeve to rotate, which in turn drives a drill bit to rotate. This allows the drill bit to loosen the soil, facilitating sampling and testing. After loosening the soil, pressing the pressing plate moves the insertion rod downwards, which in turn moves the probe to the outside of the drill bit to test the soil. This eliminates the need to carry additional sampling devices, avoiding increased carrying burden. It features convenient operation, portability, and good soil breaking effect.

[0018] 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.

[0019] Soil environmental monitoring refers to determining environmental quality (or pollution level) and its changing trends by measuring representative values ​​of factors affecting soil environmental quality. Soil monitoring, as we commonly refer to it, generally includes technical aspects such as sampling site selection, sample preparation, analytical methods, result characterization, data statistics, and quality evaluation. Some urban greening soils are quite hard, making it difficult to directly insert the probe 13. The soil pH testing device provided by this invention can loosen harder soil, thus facilitating testing by the probe 13. This eliminates the need to carry additional sampling devices, avoiding increased carrying burden. It features convenient operation, portability, and good soil-breaking effect.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a soil pH testing device, including a connecting shell 1, a fixing plate 11 rotatably connected between the inner walls of the two sides of the connecting shell 1, a gear ring 10 rotatably connected to the top of the fixing plate 11, a gear 9 rotatably connected to the top of the fixing plate 11, the gear 9 meshing with the gear ring 10, a motor fixed to the bottom of the fixing plate 11, the output end of the motor passing through the fixing plate 11 and fixed to the bottom of the gear 9, a rotating sleeve 12 fixed to the bottom of the gear ring 10, the rotating sleeve 12 passing through the bottom of the fixing plate 11 and the connecting shell 1, a drill bit 8 fixed to the outer wall of the rotating sleeve 12 below the connecting shell 1, a fixing shell 2 fixed to the top of the connecting shell 1, a rod 5 inserted through the top of the fixing shell 2, the bottom end of the rod 5 passing through into the connecting shell 1, a probe 13 fixed to its bottom end, a connection port opened through the top of the drill bit 8, and the probe 13 located in the connection port. A movable plate 14 is fixed to the outer wall of the insertion rod 5. The movable plate 14 is located inside the fixed shell 2. A spring 15 is fixed between the bottom end of the movable plate 14 and the top end of the connecting shell 1. A pressing plate 6 is fixed to the top end of the insertion rod 5.

[0021] It should be noted that when probe 13 is inserted into the soil and comes into contact with it, a redox reaction occurs, generating a current of a corresponding magnitude. The principle of probe 13 in measuring soil pH is based on an electrochemical sensor, which is existing technology. When testing harder soil, a motor drives gear 9 to rotate, which in turn drives gear ring 10 to rotate, which in turn drives rotating sleeve 12 to rotate, which in turn drives drill bit 8 to rotate. This allows the drill bit 8 to loosen the soil, facilitating sampling and testing. After loosening the soil, pressing the pressing plate 6 moves the insertion rod 5 downward, which in turn moves the moving plate 14 downward. The moving plate 14 compresses the spring 15, causing probe 13 to move to the outside of drill bit 8 to test the soil.

[0022] like Figure 1 , Figure 2 and Figure 4As shown, a mounting piece 16 is screwed onto the inner wall of the drill bit 8. A cleaning brush 17 is fixed to the inner wall of the mounting piece 16. The cleaning brush 17 contacts the surface of the probe 13 and is used to clean the surface of the probe 13. A mounting hole is provided between the rotating sleeve 12 and the drill bit 8, and a bolt is screwed into the mounting hole. A connector 7 is fixed to the bottom end of the connecting shell 1, and a sampling bottle 4 is screwed onto the outer wall of the connector 7. A controller 3 is mounted on the front of the connecting shell 1, and the controller 3 is electrically connected to the motor and the probe 13.

[0023] It should be noted that when probe 13 is inserted into the soil, the current generated after the redox reaction with the soil will be detected by the sensor. The current signal is then converted into a corresponding voltage or digital signal to represent the soil pH value. The converted voltage or digital signal is transmitted to the controller 3, which receives the transmitted data and processes it further. The controller 3 displays the processed data on the screen for the user to view. After the test is completed, the press plate 6 is released, and the spring 15 moves the moving plate 14 upward, causing the probe 13 to move into the drill bit 8. During the movement, the cleaning brush 17 on the inner wall of the mounting part 16 cleans the surface of the probe 13 to prevent soil from adhering to the surface of the probe 13 and affecting the next test. In addition, the mounting part 16 and the inner wall of the drill bit 8 are screwed together, which makes it easy to replace and clean the cleaning brush 17. In addition, by taking out the sampling bottle 4, soil can be sampled. At the same time, the sampling bottle 4 can protect the drill bit 8 to prevent it from being bumped during transportation, making it more convenient for users to test the soil pH. The inner wall of the connecting shell 1 is equipped with an installation box, which contains a battery. By charging the battery, the motor can be powered.

[0024] Working principle: During use, when testing harder soil, the sampling bottle 4 is removed, and the motor is started by the controller 3. The motor drives the gear 9 to rotate, which in turn drives the gear ring 10 to rotate, which in turn drives the rotating sleeve 12 to rotate, which in turn drives the drill bit 8 to rotate. This allows the drill bit 8 to loosen the soil, facilitating sampling and testing. After loosening the soil, pressing the pressing plate 6 moves the insertion rod 5 downward, which in turn moves the moving plate 14 downward. The moving plate 14 compresses the spring 15, causing the probe 13 to move to the outside of the drill bit 8 to test the soil. The test data is displayed on the screen of the controller 3. After the test is completed, the pressing plate 6 is released, and the spring 15 moves the moving plate 14 upward, causing the probe 13 to move into the drill bit 8. During the movement, the cleaning brush 17 on the inner wall of the mounting part 16 cleans the surface of the probe 13 to prevent soil from adhering to the surface of the probe 13 and affecting the next test.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
