Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, and in particular to a soil testing and dissolving device. Background Technology

[0002] Soil dissolution devices play a crucial role in the soil testing process. Their primary function is to mix and dissolve soil samples with appropriate solvents, enabling accurate analysis of various soil components. In practical applications, whether agricultural research institutions studying soil fertility and composition, or environmental departments monitoring soil pollution, this device is essential. It first dissolves the soil into a homogeneous solution, providing a suitable sample for various testing instruments, thus ensuring that the test results accurately reflect the soil's characteristics and condition. Current applications typically require the following technologies:

[0003] 1. Reliable mixing drive technology provides continuous and stable power to the mixing components to achieve thorough mixing of soil and solvent;

[0004] 2. A well-designed container ensures adequate dissolution space and facilitates material loading, unloading, and stirring.

[0005] 3. A robust support structure ensures the device remains stable during operation, preventing shaking from affecting the dissolving effect;

[0006] 4. The compatible transmission components accurately transmit power, ensuring the accurate execution of the stirring action.

[0007] Currently, various equipment and methods are used to achieve effective soil dissolution. Some devices employ a simple single-shaft mixing structure, with a mixing shaft at the center of the mixing tank, on which mixing blades are mounted. A motor drives the mixing shaft to rotate, mixing the soil and solvent within the tank. Other devices utilize a dual-shaft mixing method, with two mixing shafts rotating in opposite or the same direction to enhance the mixing force and range. Additionally, some more complex devices are equipped with multi-angle mixing blades to agitate the soil and solvent from different directions.

[0008] However, the above method has a prominent problem: the soil tends to stick to the inner wall of the mixing tank before it is evenly mixed. Due to the limited mixing range of the single-shaft mixing structure, the area near the tank wall is difficult to mix fully, which makes the soil easy to adhere. Soil adhering to the inner wall of the mixing tank not only prevents this part of the soil from fully participating in the dissolution process, resulting in unrepresentative test samples and affecting the accuracy of test results, but also, as the amount of adhesion increases, it may interfere with the normal operation of the mixing device, increasing the risk of equipment failure. At the same time, cleaning the adhering soil will also consume a lot of time and effort. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a soil testing and dissolving device. It solves the problem that soil tends to adhere to the inner wall of the mixing tank before it is evenly mixed. Due to the limited mixing range of the single-shaft mixing structure, the area near the tank wall is difficult to mix fully, leading to soil adhesion. Soil adhering to the inner wall of the mixing tank not only prevents this part of the soil from fully participating in the dissolving process, resulting in unrepresentative test samples and affecting the accuracy of test results, but also, as the amount of adhesion increases, it may interfere with the normal operation of the mixing device, increasing the risk of equipment failure. At the same time, cleaning the adhered soil also consumes a lot of time and effort.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A soil testing dissolving device includes a dissolving tank. A cross-shaped support ring is fixedly connected to the inner surface of the dissolving tank. A mixing mechanism for dissolving and stirring is provided inside the dissolving tank. The mixing mechanism includes a hollow rotating disk and a stirring rod. The hollow rotating disk is rotatably connected inside the dissolving tank and rotatably connected to the outer surface of the cross-shaped support ring. The stirring rod is rotatably connected inside the hollow rotating disk. A gear mechanism for self-rotation and stirring is provided on the outer surface of the cross-shaped support ring and the stirring rod. The gear mechanism includes a first spur gear and a second spur gear. The first spur gear is fixedly connected to the lower end of the cross-shaped support ring, and the second spur gear is fixedly connected to the outer surface of the stirring rod. The first spur gear and the second spur gear mesh with each other. Triangular scrapers are fixedly connected to both sides of the stirring rod.

[0012] Preferably, a feeding hopper is fixedly connected to the outer surface of the dissolving tank, and a discharge valve is provided at the lower end of the dissolving tank.

[0013] Preferably, a dissolving support is fixedly connected to one end of the outer surface of the dissolving tank near the feeding hopper, and a set of self-locking casters is provided at the lower end of the dissolving support.

[0014] Preferably, a stirring drive motor is fixedly connected to the outer surface of the dissolving support, and synchronous pulleys are sleeved on the outer surfaces of both the hollow rotating disk and the stirring drive motor.

[0015] Preferably, a timing belt is fitted onto the outer surfaces of the two timing pulleys.

[0016] Preferably, a baffle is fixedly connected to the upper end of the dissolution support.

[0017] Preferably, the baffle is disposed on the outer surface of the two synchronous pulleys.

[0018] Preferably, both the dissolving tank and the dissolving support are fixedly connected to a U-shaped handle rod on their outer surfaces.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. During the rotation of the hollow rotating disc, the stirring rod revolves. As the stirring rod rotates, it engages with the first spur gear, which is fixed in place by the second spur gear fitted onto its surface. This causes the stirring rod to rotate around the center of the dissolving tank, performing a stirring operation. This increases the mixing area and reduces dead spots. Furthermore, the two triangular scrapers installed on both sides of the stirring rod are in close contact with the surface of the dissolving tank. The rotation of the stirring rod drives these triangular scrapers to clean the inner wall of the dissolving tank. This effectively prevents soil from adhering to the tank wall before it is evenly mixed, avoiding incomplete dissolution due to soil adhesion. This ensures the smooth progress of the entire dissolution process, improves the dissolution effect, and also helps to enhance the accuracy of the test results.

[0021] 2. Before use, the dissolving support can be moved by pulling the two U-shaped handles. The dissolving support is moved by a set of self-locking casters installed at its lower end, making it easier to move and transfer the device. This allows the device to be moved flexibly between different locations according to actual work needs. Whether adjusting the position inside the laboratory or moving it between different sites, it becomes easy. Attached Figure Description

Detailed Implementation

[0028] This application provides a soil dissolution device that effectively solves the problem of soil easily adhering to the inner wall of the mixing tank before it is evenly mixed. Due to the limited mixing range of the single-shaft mixing structure, the area near the tank wall is difficult to mix thoroughly, leading to soil adhesion. Soil adhering to the inner wall not only prevents this portion of soil from fully participating in the dissolution process, resulting in unrepresentative test samples and affecting the accuracy of the test results, but also, as the amount of adhering soil increases, it may interfere with the normal operation of the mixing device, increasing the risk of equipment failure. Furthermore, cleaning the adhering soil consumes a significant amount of time and effort. During the rotation of the hollow rotating disc, the mixing rod revolves, and as the mixing rod rotates... During the process, the first spur gear, which is fixed in position by the second spur gear sleeved on its surface, causes the stirring rod to rotate around the center of the dissolving tank, thereby increasing the mixing area and reducing dead spots. Furthermore, the two triangular scrapers installed on both sides of the stirring rod are in close contact with the surface of the dissolving tank. The rotation of the stirring rod drives the triangular scrapers to scrape and clean the inner wall of the dissolving tank. This effectively prevents soil from adhering to the tank wall before it is evenly mixed, avoiding incomplete dissolution due to soil adhesion. This ensures the smooth progress of the entire dissolution process, improves the dissolution effect, and also helps to improve the accuracy of the test results.

[0029] Example

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that soil easily adheres to the inner wall of the mixing tank before it is evenly mixed. Due to the limited mixing range of the single-shaft mixing structure, the area near the tank wall is difficult to mix fully, leading to soil adhesion. Soil adhering to the inner wall of the mixing tank not only prevents this part of the soil from fully participating in the dissolution process, resulting in unrepresentative test samples and affecting the accuracy of test results, but also, as the amount of adhesion increases, it may interfere with the normal operation of the mixing device, increasing the risk of equipment failure. At the same time, cleaning the adhered soil also consumes a lot of time and effort. The overall idea is as follows: a soil The dissolving device includes a dissolving tank 11. A cross-shaped support ring 12 is fixedly connected to the inner surface of the dissolving tank 11. A mixing mechanism for dissolving and stirring is provided inside the dissolving tank 11. The mixing mechanism includes a hollow rotating disk 13 and a stirring rod 14. The hollow rotating disk 13 is rotatably connected inside the dissolving tank 11 and rotatably connected to the outer surface of the cross-shaped support ring 12. The stirring rod 14 is rotatably connected inside the hollow rotating disk 13. A gear mechanism for self-rotation and stirring is provided on the outer surfaces of the cross-shaped support ring 12 and the stirring rod 14. The gear mechanism includes a first spur gear 15 and a second spur gear 16. Wheel 15 is fixedly connected to the lower end of cross-shaped support ring 12. Second spur gear 16 is fixedly connected to the outer surface of stirring rod 14. First spur gear 15 and second spur gear 16 mesh with each other. Triangular scrapers 17 are fixedly connected to both sides of stirring rod 14. Hollow rotating disk 13 rotates inside dissolving tank 11, located on the surface of cross-shaped support ring 12. Hollow rotating disk 13 has a hollow structure, and a round rod is installed at its center. A set of synchronous belts 25 is sleeved on the surface of the round rod. The round rod passes through the hollow part inside cross-shaped support ring 12 and first spur gear 15. Baffle 26 installed on the surface of dissolving support 21 is used to control the rotation. The step wheel 24 and the timing belt 25 provide shielding protection. During the rotation of the hollow rotating disk 13, the stirring rod 14 is driven to revolve. During the rotation of the stirring rod 14, the first spur gear 15 is fixed in the meshing position through the second spur gear 16 sleeved on its surface. This causes the stirring rod 14 to rotate around the center of the dissolving tank 11 and perform a stirring operation, thereby increasing the mixing area and reducing the dead points. In addition, the two triangular scrapers 17 installed on both sides of the stirring rod 14 are in contact with the surface of the dissolving tank 11. The rotation of the stirring rod 14 drives the triangular scrapers 17 to perform a scraping and cleaning operation on the inner wall of the dissolving tank 11.

[0031] A feeding hopper 18 is fixedly connected to the outer surface of the dissolving tank 11, and a discharge valve 19 is provided at the lower end of the dissolving tank 11. Soil and solution for dissolution testing are fed into the dissolving tank 11 along the feeding hopper 18. The soil particles are stirred by the rotation of the stirring rod 14 inside the dissolving tank 11 to ensure full contact between the soil particles and the solvent, accelerate the diffusion of the solute, and thus promote the dissolution process. Stirring can break the solvent boundary layer around the soil particles, allowing fresh solvent to continuously contact the soil and accelerate the dissolution rate. After the soil is stirred and dissolved, a homogeneous solution is obtained. The solution is discharged through the discharge valve 19 for subsequent testing. The homogeneous solution prepared by dissolving the soil results in a more uniform morphology of the test sample, which helps to improve the sensitivity and accuracy of the detection method. The soil can be analyzed using various instruments in the solution state. There are relatively fewer interfering factors in the liquid state, which can more accurately determine the content or concentration of the target substance.

[0032] A dissolving support 21 is fixedly connected to one end of the outer surface of the dissolving tank 11 near the feeding hopper 18. A set of self-locking universal wheels 22 is provided at the lower end of the dissolving support 21. A stirring drive motor 23 is fixedly connected to the outer surface of the dissolving support 21. Synchronous pulleys 24 are sleeved on the outer surfaces of both the hollow rotating disc 13 and the stirring drive motor 23. Synchronous belts 25 are sleeved on the outer surfaces of the two synchronous pulleys 24. A baffle 26 is fixedly connected to the upper end of the dissolving support 21 and is provided on the outer surface of the two synchronous pulleys 24. A U-shaped handle rod 27 is fixedly connected to the outer surfaces of both the dissolving tank 11 and the dissolving support 21. Before use, the dissolving support 21 can be moved by holding the two U-shaped handles 27. The dissolving support 21 is moved by a set of self-locking casters 22 installed at its lower end, making it easier to move and transfer the device. The self-locking casters 22 have a locking function, which can lock the device when it is idle, thereby enhancing its stability. When stirring, the stirring drive motor 23 installed on the surface of the dissolving support 21 is started. The output shaft of the stirring drive motor 23 drives the hollow rotating disk 13 to rotate synchronously through the transmission of the synchronous pulley 24 and the synchronous belt 25.

[0033] To address the problems existing in the prior art, this utility model provides a soil testing and dissolving device. During the rotation of the hollow rotating disk 13, the stirring rod 14 revolves. During the rotation of the stirring rod 14, it meshes with the first spur gear 15, which is fixed at the position of the second spur gear 16 sleeved on its surface. This causes the stirring rod 14 to rotate around the center of the dissolving tank 11, performing a stirring operation by increasing the mixing area and reducing dead spots. Furthermore, the two triangular scrapers 17 installed on both sides of the stirring rod 14 are in contact with the surface of the dissolving tank 11. The rotation of the stirring rod 14 drives the triangular scrapers 17 to scrape and clean the inner wall of the dissolving tank 11. This effectively prevents soil from adhering to the tank wall before it is evenly mixed, avoiding incomplete dissolution due to soil adhesion. This ensures the smooth progress of the entire dissolution process, improves the dissolution effect, and also helps to improve the accuracy of the test results.

[0034] Working principle:

[0035] The first step involves feeding the soil and solution used for dissolution testing into the dissolution tank 11 via the feed hopper 18. The rotating stirring rod 14 within the dissolution tank 11 agitates the soil particles, ensuring full contact with the solvent and accelerating solute diffusion, thus promoting the dissolution process. Stirring also breaks down the solvent boundary layer around the soil particles, allowing fresh solvent to continuously contact the soil and further speeding up the dissolution. After the soil is dissolved, a homogeneous solution is obtained. This solution is discharged through the discharge valve 19 for subsequent testing. Dissolving the soil to create a homogeneous solution results in a more uniform sample morphology, which helps improve the sensitivity and accuracy of the detection method. The soil in solution state can then be analyzed using various instruments. In liquid state, there are relatively fewer interfering factors, allowing for more precise determination of the content or concentration of the target substance.

[0036] The second step involves moving the dissolving support 21 by pulling on the two U-shaped handles 27 before use. The dissolving support 21 is moved via a set of self-locking casters 22 mounted at its lower end, facilitating easier movement. These casters have a locking function, allowing the device to be locked when idle, enhancing its stability. During stirring, the stirring drive motor 23 mounted on the surface of the dissolving support 21 is activated. The output shaft of the stirring drive motor 23 synchronously drives the hollow rotating disk 13 to rotate via a synchronous pulley 24 and a synchronous belt 25. The hollow rotating disk 13 rotates inside the dissolving tank 11, located on the surface of the cross-shaped support ring 12. The hollow rotating disk 13 has a hollow structure with a round rod mounted at its center, and the surface of the round rod is fitted with… A set of synchronous belts 25 is provided. A round rod passes through the hollow part inside the cross-shaped support ring 12 and the first spur gear 15. The baffle 26 installed on the surface of the dissolving bracket 21 is used to provide shielding protection for the rotating synchronous wheel 24 and the synchronous belt 25. During the rotation of the hollow rotating disk 13, the stirring rod 14 is driven to revolve. During the rotation of the stirring rod 14, the first spur gear 15 is fixed in the meshing position through the second spur gear 16 sleeved on its surface. This causes the stirring rod 14 to rotate around the center of the dissolving tank 11 and perform a stirring operation, thereby increasing the mixing area and reducing the dead points. The two triangular scrapers 17 installed on both sides of the stirring rod 14 are in contact with the surface of the dissolving tank 11. The rotation of the stirring rod 14 drives the triangular scrapers 17 to perform a scraping and cleaning operation on the inner wall of the dissolving tank 11.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
