[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a soil testing sample dissolution device, including a frame 1, a quantitative addition component 2, and a support component 3. The quantitative addition component 2 is located at the upper part of the frame 1, and the support component 3 is located at the lower part of the frame 1. The support component 3 is used to support the dissolution cup 4. The quantitative addition component 2 includes a driven gear 21 and a first motor 22. The output shaft of the first motor 22 is fixedly connected to a driving gear 23, and the driving gear 23 and the driven gear 21 mesh and transmit power. Multiple solvent storage tanks 24 are provided on the driven gear 21. A quantitative pump 25 is installed at the lower end of the solvent storage tank 24. One end of the quantitative pump 25 is connected to an addition tube 26. When the quantitative pump 25 is working, it can extract a quantitative amount of solvent, and the solvent is discharged through the addition tube 26.

[0024] The quantitative addition component 2 is used to quantitatively add the solvent required for dissolving the soil test sample. Multiple solvent storage tanks 24 are pre-stored with the types of solvents required for dissolution. The support component 3 is used to support and position the dissolution cup 4. The dissolution cup 4 containing the soil test sample is placed on the support component 3. At this time, the dissolution cup 4 is directly below the addition tube 26. The solvent flowing out of the addition tube 26 can enter the dissolution cup 4. The support component 3 can drive the dissolution cup 4 to rotate. When one or more solvents are quantitatively added into the dissolution cup 4, the dissolution cup 4 rotates under the drive of the support component 3. The rotational force is used to stir and mix the solvent and the soil test sample evenly, thereby dissolving the soil test sample.

[0025] When the first motor 22 is working, it drives the driving gear 23 at one end, which in turn drives the driven gear 21 to rotate relative to the top frame 13 through the meshing transmission between the teeth. The driven gear 21 drives the multiple sets of solvent storage tanks 24 on its upper part to rotate synchronously. Each time the driven gear 21 rotates a certain angle, it switches the multiple sets of solvent storage tanks 24 in sequence, thereby adding multiple solvents to the dissolving cup 4 in a quantitative manner. The amount of solvent added is controlled by the metering pump 25, and the type of solvent is selected by the first motor 22. Under the drive of the first motor 22, the solvent storage tank 24 at the designated position is driven to the adding position. There is no need to manually take a quantitative amount of solvent, which reduces preparation time and improves dissolving efficiency.

[0026] Multiple solvent storage tanks 24 are evenly distributed along the circumference of the driven gear 21. The other end of the metering pump 25 is connected to the chamber of the solvent storage tank 24. The driven gear 21 rotates a certain angle each time, so that when switching the solvent storage tank 24, the addition tube 26 at the lower end of the solvent storage tank 24 is just above the dissolving cup 4.

[0027] The frame 1 includes a base frame 11, a vertical frame 12 and a top frame 13. The base frame 11 is located at the lower end of the vertical frame 12, and the top frame 13 is located at the upper end of the vertical frame 12. The base frame 11, the vertical frame 12 and the top frame 13 are welded and fixedly connected.

[0028] The first motor 22 is mounted and fixed on the top of the support frame 12. The driven gear 21 is rotatably connected to the top frame 13. The top frame 13 is fixed, while the driven gear 21 can rotate relative to the top frame 13.

[0029] The supporting component 3 includes a stud 31, a bracket 32, a second motor 33, and a positioning seat 34. The stud 31 is fixedly mounted on the base frame 11. The bracket 32 ​​has a through hole 321. The stud 31 passes through the through hole 321 of the bracket 32. The stud 31 and the bracket 32 ​​are fixedly connected by a locking nut 35.

[0030] like Figure 3 As shown, there are two sets of locking nuts 35. One set of locking nuts 35 is located at the upper end of the connection between the bracket 32 ​​and the stud 31, and the other set of locking nuts 35 is located at the lower end of the connection between the bracket 32 ​​and the stud 31. The bracket 32 ​​and the stud 31 are fixedly connected by the two sets of locking nuts 35.

[0031] When the locking nut 35 is loosened, the height of the bracket 32 ​​on the stud 31 can be adjusted. After adjustment, the locking nut 35 is tightened to secure it. By adjusting the height of the bracket 32, the height of the positioning seat 34 can be adjusted accordingly, that is, the height of the dissolving cup 4 can be adjusted accordingly. The height of the dissolving cup 4 can be adjusted according to actual usage requirements.

[0032] The second motor 33 is mounted and fixed on the bracket 32. The lower end of the positioning seat 34 is welded and fixed with a connecting shaft 341. The output shaft of the second motor 33 and the connecting shaft 341 of the positioning seat 34 are fixedly connected by a coupling. When the second motor 33 is working, it drives the connecting shaft 341 at one end to rotate, and drives the positioning seat 34 to rotate through the connecting shaft 341. When the dissolving cup 4 is placed on the positioning seat 34, the dissolving cup 4 rotates synchronously with the positioning seat 34 to achieve the mixing of solvent and soil.

[0033] The positioning seat 34 includes a positioning groove 342 for placing the dissolving cup 4.

[0034] The inner wall of the positioning groove 342 is provided with an elastic liner 343. The elastic liner 343 has a certain elasticity. When the dissolving cup 4 is placed, the outer side of the dissolving cup 4 is in close contact with the elastic liner 343. The dissolving cup 4 is fixed by the rebound force and friction of the elastic liner 343, which improves the stability of the dissolving cup 4 during rotation.

[0035] The dissolving cup 4 is located directly below the adding tube 26, and the solvent flowing out of the adding tube 26 can just enter the dissolving cup 4.

[0036] Working principle: During use, multiple solvent storage tanks 24 are pre-stored with the types of solvents required for dissolution. The dissolution cup 4 containing the soil test sample is placed on the positioning seat 34 of the support component 3. The outer side of the dissolution cup 4 is in close contact with the elastic liner 343. The dissolution cup 4 is fixed by the rebound force and friction of the elastic liner 343. The amount of solvent added is controlled by the metering pump 25, and the type of solvent is selected by the drive control of the first motor 22. Under the drive of the first motor 22, the solvent storage tank 24 at the designated position is driven to the addition position. The metering pump 25 works to draw a metered amount of solvent. The solvent is discharged through the addition tube 26 and just enters the dissolution cup 4. When one or more solvents are added to the dissolution cup 4 in a metered manner, the dissolution cup 4 rotates under the drive of the second motor 33 of the support component 3. The rotational force is used to stir and mix the solvent and the soil test sample evenly, thereby dissolving the soil test sample.

[0037] 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 claims and their equivalents.
