Description

Technical Field

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

[0002] Soil testing primarily involves determining representative values ​​of factors affecting soil environmental quality to ascertain environmental quality (or pollution level) and its changing trends. Soil testing is a systematic process, including sample collection, sample dissolution, sample testing, and application of test results. Soil sample dissolution requires a dissolution device to facilitate analysis by testing instruments. After use, the dissolution chamber is cleaned to minimize impact on future use. However, existing soil testing dissolution devices typically have fixed dissolution chambers that cannot be disassembled, making cleaning inconvenient. Furthermore, damaged dissolution chambers cannot be replaced individually, increasing maintenance difficulty. Secondly, existing soil testing dissolution devices often use stirring rods to agitate the soil and dissolving solution. These rods usually rotate in only one direction, resulting in a monotonous movement pattern of the soil and solution. This can create fixed eddies or dead zones within the dissolution chamber, preventing some areas of the soil sample from fully contacting the dissolving solution, thus affecting dissolution efficiency and uniformity.

[0030] In this embodiment, when the inside of the dissolving cylinder 3 needs to be cleaned, the two handles 9 are rotated in sequence. The handles 9 drive the screw 8 to rotate. Since the screw 8 is threadedly connected to the drive plate 10, the drive plate 10 drives the two fixed rods 11 to move, so that one end of the fixed rod 11 moves out of the limiting seat 5, releasing the fixing of the limiting seat 5. The dissolving cylinder 3 is pulled upward, and the dissolving cylinder 3 drives the limiting ring 4 to move. The limiting ring 4 drives the limiting seat 5 to separate from the limiting groove 6. At the same time, the dissolving cylinder 3 drives the stirring shaft 12, stirring rod, rotating seat 14 and gear ring 25 to move, thereby disassembling the dissolving cylinder 3. After cleaning, the reverse operation can be used to install it. At the same time, the square rod 19 is inserted into the square hole 20, and the gear 24 meshes with the gear ring 25.

[0031] Please see Figures 1-5 As an embodiment for rapidly mixing and dissolving soil and solvent: Multiple second stirring rods 15 are fixedly installed inside the dissolving cylinder 3; a drive chamber 16 is provided inside the base 1; a motor 17 is fixedly installed inside the drive chamber 16; a drive rod 18 is fixedly installed at the drive end of the motor 17; a square rod 19 is fixedly installed at the upper end of the drive rod 18 through the drive chamber 16; one end of the square rod 19 is inserted into a rotating seat 14; a square hole 20 that mates with the square rod 19 is provided at the lower end of the rotating seat 14; a rotating rod 21 is rotatably installed inside the drive chamber 16; transmission wheels 22 are fixedly installed on the rotating rod 21 and the drive rod 18 respectively; a transmission belt 23 connects the two transmission wheels 22; and the upper end of the rotating rod 21 passes through the drive chamber 16 and is fixedly installed... There is a gear 24, which meshes with a gear ring 25. The gear ring 25 is fixedly installed on the outside of the dissolving cylinder 3. A cover 26 is movably installed on the upper end of the dissolving cylinder 3. Two fixed shells 27 are fixedly installed on the cover 26. A bidirectional lead screw 28 is rotatably installed in each of the two fixed shells 27. A handle 29 is fixedly installed on the bidirectional lead screw 28 between the two fixed shells 27. A moving rod 30 is movably installed in each fixed shell 27. The moving rod 30 is threadedly connected to the bidirectional lead screw 28. One end of the moving rod 30 passes through the fixed shell 27 and is fixedly installed with a fixing block 31. The fixing block 31 is L-shaped. Two fixing seats 32 are fixedly installed on the outside of the dissolving cylinder 3. One end of each fixing block 31 is inserted into the fixing seat 32.

[0032] More specifically, when it is necessary to dissolve a soil sample, the soil to be dissolved and the dissolving solution are placed into the dissolving cylinder 3. The cover 26 is placed on the top of the dissolving cylinder 3, and the two fixing blocks 31 are aligned with the fixing seats 32. The handle 29 is turned, which drives the bidirectional lead screw 28 to rotate. Since the bidirectional lead screw 28 has two threaded areas in opposite directions, the two moving rods 30 move in adjacent directions. The moving rods 30 drive the fixing blocks 31 to move, so that one end of the two fixing blocks 31 is inserted into the two fixing seats 32 respectively, thus fixing the cover 26 into the dissolving cylinder 3. The motor 17 is started, which drives the drive rod 18 to rotate. The drive rod 18 drives the square rod 19 to rotate, and the square rod 19 drives the rotation through the square hole 20. Rotating seat 14 rotates, driving stirring shaft 12 to rotate. Stirring shaft 12 drives multiple first stirring rods 13 to rotate. Simultaneously, driving rod 18 drives transmission wheel 22 to rotate. Transmission wheel 22 drives rotating rod 21 to rotate in the same direction as driving rod 18 via transmission belt 23 and another transmission wheel 22. Rotating rod 21 drives gear 24 to rotate. Since gear 24 meshes with gear ring 25, gear 24 drives gear ring 25 to rotate in the opposite direction. Gear ring 25 drives dissolving cylinder 3 to rotate around the point of rotational connection with limiting ring 4. At the same time, dissolving cylinder 3 drives second stirring rod 15 to rotate, so that second stirring rod 15 rotates in the opposite direction to first stirring rod 13, thereby uniformly stirring the soil and dissolving liquid in dissolving cylinder 3.

[0033] In summary, during use or operation of the entire equipment: the entire dissolving device is a small device for stirring and dissolving soil samples. When it is necessary to clean the inside of the dissolving cylinder 3, rotate the two handles 9 in sequence. The handles 9 drive the screw 8 to rotate. Since the screw 8 is threadedly connected to the drive plate 10, the drive plate 10 drives the two fixed rods 11 to move, causing one end of the fixed rod 11 to move out of the limiting seat 5, releasing the fixation of the limiting seat 5. Pull the dissolving cylinder 3 upward, and the dissolving cylinder 3 drives the limiting ring 4 to move. The limiting ring 4 drives the limiting seat 5 to separate from the limiting groove 6. At the same time, the dissolving cylinder 3 drives the stirring shaft 12, stirring rod, rotating seat 14 and gear ring 25 to move, thereby disassembling the dissolving cylinder 3. After cleaning, the reverse operation can be used to install it, and at the same time, the square rod 19 is inserted into the square hole 20, and the gear 24 meshes with the gear ring 25.

[0034] When soil samples need to be dissolved, the soil and dissolving solution are placed into the dissolving cylinder 3. The cover 26 is placed on top of the dissolving cylinder 3, and the two fixing blocks 31 are aligned with the fixing seats 32. The handle 29 is turned, which drives the bidirectional lead screw 28 to rotate. Since the bidirectional lead screw 28 has two threaded areas in opposite directions, the two moving rods 30 move in adjacent directions. The moving rods 30 drive the fixing blocks 31 to move, so that one end of the two fixing blocks 31 is inserted into the two fixing seats 32 respectively, thus fixing the cover 26 into the dissolving cylinder 3. The motor 17 is started, which drives the drive rod 18 to rotate. The drive rod 18 drives the square rod 19 to rotate, and the square rod 19 drives the rotating seat 1 through the square hole 20. 4. Rotation: The rotating seat 14 drives the stirring shaft 12 to rotate, which in turn drives multiple first stirring rods 13 to rotate. Simultaneously, the drive rod 18 drives the transmission wheel 22 to rotate. The transmission wheel 22, through the transmission belt 23 and another transmission wheel 22, drives the rotating rod 21 to rotate in the same direction as the drive rod 18. The rotating rod 21 drives the gear 24 to rotate. Since the gear 24 is meshed with the gear ring 25, the gear 24 drives the gear ring 25 to rotate in the opposite direction. The gear ring 25 drives the dissolving cylinder 3 to rotate around the point of rotational connection with the limiting ring 4. At the same time, the dissolving cylinder 3 drives the second stirring rod 15 to rotate, so that the second stirring rod 15 rotates in the opposite direction to the first stirring rod 13, thereby uniformly stirring the soil and dissolving liquid in the dissolving cylinder 3.

[0035] A controller is provided on one side of the base 1. The entire device is controlled by the controller. Since the device matched with the controller is a common device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
