[0002] Soil CEC value, or soil cation exchange capacity, refers to the number of centimoles of exchangeable cations that can be adsorbed per kilogram of soil under certain pH conditions. It is an important indicator for measuring soil's ability to retain and supply nutrients as well as its buffering capacity.
[0003] For example, Chinese patent CN212722763U discloses a soil cation exchange capacity measuring device, belonging to the field of cation exchange capacity measurement technology. It includes a base, a support plate, a lifting mechanism, an operating plate, a liquid dispenser, and a driving mechanism. The support plate is rotatably connected to the base. Multiple test tubes are mounted on the support plate. The lifting mechanism is fixed to the support plate. The operating plate is connected to the lifting mechanism. Multiple stirring rods and a motor for driving the stirring rods are mounted on the operating plate. Each stirring rod is located on the lower end face of the operating plate and corresponds to a test tube. The liquid dispenser is located on one side of the base and is used to add reagents to each test tube. The driving mechanism is located on the base and is connected to the support plate for driving the support plate to rotate. The soil cation exchange capacity measuring device provided by this invention can quickly add reagents to multiple test tubes and quickly and thoroughly stir the reagents, reducing the labor intensity of workers and greatly improving work efficiency.
[0004] The aforementioned patent has the following problems:
[0005] This patent has some drawbacks in its use, such as: the device uses multiple motors, and the simultaneous operation of multiple motors consumes more electricity, significantly increasing electricity costs; also, the test tube is not fixed when stirring the liquid, which may cause it to shake and spill liquid out. Therefore, we propose a soil CEC value measuring device. Utility Model Content
[0006] The purpose of this invention is to provide a soil CEC value measuring device to solve the problems mentioned in the background art.
[0007] In view of this, the present invention provides a soil CEC value measuring device, including a base and several test tubes, and further including:
[0008] A fixed column is fixedly installed on a base. A sliding plate is slidably installed on the fixed column. Several sealing covers are rotatably installed on the bottom of the sliding plate. A rotating column is fixedly installed at the bottom of each of the sealing covers. Several stirring blades are fixedly installed on each of the rotating columns.
[0009] A fixing block is fixedly installed on the top of the base. A working cavity is opened in the fixing block. Several test tubes are inserted into the working cavity. Sliding blocks are slidably installed in the working cavity on one side of several test tubes. The sides of several sliding blocks that are far apart from each other are in close contact with several test tubes.
[0010] A drive assembly located within a sliding plate;
[0011] A power assembly, which is located within a fixed block.
[0012] In this technical solution, the soil is first placed in several test tubes, and then the test tubes are inserted into the working chamber. Through the set power component, several sliding blocks can be driven to slide and move away from each other. When the several sliding blocks are in close contact with the several test tubes, the test tubes can be fixed on the fixed blocks, and the fixing effect is good.
[0013] The staff then added the required reagents into several test tubes. Through the set drive components, several sealing caps and several rotating columns could be driven to rotate. The rotating columns drove several stirring blades to rotate. The stirring blades could stir the reagents and soil in several working chambers, saving the overall cost of using the device.
[0014] In the above technical solution, the driving component further includes:
[0015] The power chamber is located inside a sliding plate. A first motor is fixedly mounted on the top of the sliding plate. The output shaft of the first motor extends through the sliding plate into the power chamber and is fixedly mounted with a first gear. Several second gears are meshed around the periphery of the first gear. The lower ends of the several second gears all extend through the power chamber and are fixedly connected to several sealing covers respectively. The output shaft of the first motor is rotatably connected to the sliding plate and the power chamber. The first gear and the several second gears are all rotatably connected to the power chamber.
[0016] In this technical solution, the first motor is started, and the first motor is powered on and drives the first gear to rotate. The first gear drives several second gears that mesh with it to rotate. The several second gears drive several sealing covers and several rotating columns to rotate. The several rotating columns drive several stirring blades to rotate. The several stirring blades can stir the reagents and soil in several working chambers. Moreover, the above operations can be completed by only one first motor, saving the overall cost of the device.
[0017] In the above technical solution, the power component further includes:
[0018] The second motor is fixedly installed inside the working chamber and located below several test tubes. The output shaft of the second motor is fixedly installed with a disc. Several arc-shaped grooves are opened on the disc. Guide posts are slidably installed in each of the arc-shaped grooves. The upper ends of the guide posts pass through the arc-shaped grooves and are fixedly connected to several sliding blocks. The disc is rotatably connected to the working chamber.
[0019] In this technical solution, soil is first placed in several test tubes, and then the test tubes are inserted into the working chamber. Next, the second motor is started, and the second motor is powered on and drives the disc to rotate. The disc drives several guide columns to slide and move away from each other through several arc grooves. The guide columns drive several sliding blocks to slide and move away from each other. When the anti-slip rubber pads on the sliding blocks are in close contact with the test tubes, the second motor is turned off, so that the test tubes can be fixed on the fixing blocks with good fixing effect.
[0020] In the above technical solution, a sliding groove is further provided in the sliding plate, and a limiting post is slidably installed in the sliding groove. One end of the limiting post is fixedly installed with several springs that are fixed to the inner wall of the sliding groove. The top of the limiting post passes through the sliding groove and extends to the outside. Two grooves are provided on the fixed post. The other end of the limiting post passes through the sliding groove and extends into the corresponding groove. The other end of the limiting post is inserted into the corresponding groove.
[0021] In this technical solution, the limiting post is pulled to slide towards the spring, while several springs are compressed and contracted. When one end of the limiting post disengages from the upper groove, the sliding plate is pulled downward. When the sliding plate moves to the appropriate position, the limiting post is released. Under the action of the rebound force of several springs, the limiting post slides away from the spring. Finally, the limiting post is inserted into the lower groove, which can fix the position of the sliding plate.
[0022] In the above technical solution, further, a plurality of the test tubes are distributed in a ring at equal intervals on the fixed block.
[0023] In this technical solution, the stability of several test tubes during stirring is ensured.
[0024] In the above technical solution, furthermore, the plurality of stirring blades are respectively distributed in a cross pattern on the plurality of rotating columns.
[0025] In this technical solution, it is ensured that the soil and reagents in several test tubes can be mixed evenly.
[0026] In the above technical solution, furthermore, anti-slip rubber pads are fixedly installed on the sides of the plurality of sliding blocks that are far apart from each other.
[0027] In this technical solution, the positions of several test tubes can be fixed when the anti-slip rubber pads on several sliding blocks are in close contact with several test tubes respectively.
[0028] The beneficial effects of this utility model are:
[0029] 1. The soil CEC value measuring device starts with a first motor, which drives the first gear to rotate. The first gear drives several second gears meshing with it to rotate. The several second gears drive several sealing covers and several rotating columns to rotate. The several rotating columns drive several stirring blades to rotate. The several stirring blades can stir the reagents and soil in several working chambers. Moreover, the above operations can be completed by only one first motor, saving the overall cost of the device.
[0030] 2. In this soil CEC value measuring device, several test tubes are inserted into the working chamber. Then, the second motor is started.
