Description
Technical Field
[0001] The present application relates to the field of soil exploration material analysis equipment, and in particular to a convenient and efficient soil particle test and analysis device. Background Art
[0002] At present, particle analysis test is one of the routine tests for soil. Its purpose is to determine the percentage of various particle groups in the total mass of dry soil, so as to understand the distribution of particle size, provide for soil classification and rough judgment of soil engineering properties and material selection. Particle analysis test on soil samples can quantitatively describe the content of each particle group in soil particles, and provide a basis for engineering classification of soil and understanding of soil engineering properties. At the same time, when judging the liquefaction of foundation soil, the clay content of soil must be used, which requires quantitative analysis of clay content through particle analysis test. Therefore, particle analysis test is one of the most important test items in geotechnical test. When conducting particle analysis test, put the soil block into the measuring cylinder, then add liquid water into the measuring cylinder, and then the operator puts the stirring plate into the measuring cylinder through the stirring rod, so that the operator can stir the suspension in the measuring cylinder through the stirring plate at one end of the stirring rod.
[0003] In the related art, the existing operation is a group of particle tests of 60 test samples, which completely relies on manual pulling up and down of the stirring plate. During the stirring process, the stirring plate stirs up and down along the entire suspension depth in the measuring cylinder for 1 minute, and reciprocates 30 times each. Only when the time is up can it be switched to the next measuring cylinder containing the sample to continue stirring. During stirring, the operator controls the pulling speed of the stirring plate during stirring, thereby preventing the suspension in the measuring cylinder from splashing out of the cylinder. As the operator completes the stirring of the measuring cylinder, the soil particles in the suspension of the measuring cylinder are evenly distributed. At the same time, another person is required to use a hydrometer to read the sample data after stirring. In this case, two test personnel are required to complete such a test, one responsible for the hydrometer reading, and the other responsible for pulling the stirrer up and down for an hour without stopping. As a result, the entire test analysis process is very cumbersome, not only consuming a lot of manpower and material resources, but also very inefficient. Summary of the invention
[0004] The present application provides a convenient and efficient soil particle test and analysis device, the purpose of which is to optimize the soil material test and analysis process, thereby significantly improving the convenience and efficiency of soil material test and analysis.
[0005] The present application provides a convenient and efficient soil particle test analysis device, which adopts the following technical solutions:
[0006] A convenient and efficient soil particle test and analysis device comprises a mounting frame and a placing table, wherein the placing table is fixed to the bottom of the mounting frame, a measuring cylinder is vertically fixed to the placing table, a stirring plate and a hydrometer are arranged on the mounting frame, the stirring plate is used to stir the suspension in the measuring cylinder, after the stirring plate completes stirring the suspension in the measuring cylinder, the hydrometer is used to perform buoyancy detection and analysis on the suspension in the measuring cylinder after stirring; the stirring plate and the hydrometer both slide on the mounting frame along three directions of X, Y and Z, and the stirring plate and the hydrometer are spaced apart in the horizontal direction, and the spacing between the stirring plate and the hydrometer is consistent with the spacing between two adjacent measuring cylinders; the stirring plate is arranged to rotate in the horizontal direction while sliding.
[0007] By adopting the above technical solution, when the stirring plate slides from the measuring cylinder to the next measuring cylinder after stirring, the hydrometer can extend into the measuring cylinder that has just been stirred to perform buoyancy detection. As the stirring plate stirs in the next measuring cylinder, during this process, the hydrometer can complete the detection and analysis of the buoyancy in the previous measuring cylinder. Similarly, while the stirring plate stirs the suspension in the next measuring cylinder, the hydrometer can simultaneously perform buoyancy detection and analysis on the suspension in the previous measuring cylinder, thereby optimizing the soil material test analysis process and significantly improving the convenience and test efficiency of soil material test analysis.
[0008] The stirring plate can rotate while stirring the suspension in the measuring cylinder. This allows the stirring plate to not only stir the suspension in the measuring cylinder by stirring it up and down, but also to increase the amplitude of stirring the suspension in the measuring cylinder by its own rotation during the process of stirring it up and down. This allows the stirring plate to stir the suspension in the measuring cylinder more evenly. For suspensions containing solid particles, increasing the stirring amplitude while stirring evenly can effectively prevent the solid particles from settling, maintain the stability of the suspension, and thus improve the accuracy of the test analysis results of soil materials.
[0009] Preferably, a support rod is installed on the top of the stirring plate, and the hydrometer is connected to the support rod through corresponding connecting rods and connecting plates; a first mounting cylinder with a hollow interior is installed at the bottom of the support rod, and the top of the stirring plate is integrally connected with a first rotating gear in a horizontal direction, the stirring plate extends from the bottom of the first mounting cylinder, and the first rotating gear is located in the first mounting cylinder; a linkage gear is vertically arranged in the first mounting cylinder, the bottom of the linkage gear is meshed and connected with the first rotating gear, and the top of the linkage gear is meshed and connected with a second rotating gear, and the end of the second rotating gear away from the linkage gear is integrally connected with a first rotating shaft in a vertical direction, and the top of the first rotating shaft extends upward from the support rod and is connected to a first driving motor.
[0010] By adopting the above technical solution, specifically, when the stirring plate is extending downward into the measuring cylinder, the first drive motor is turned on, and the first rotating shaft is driven by the first drive motor to rotate. The first rotating shaft drives the second rotating gear to rotate during the rotation process, and the second rotating gear is meshed with the linkage gear during the rotation process, thereby driving the linkage gear to rotate. After the linkage gear rotates, it meshes with the first rotating gear, and then drives the stirring plate to rotate in the horizontal direction through the linkage gear. In this state, the stirring plate is driven by the first drive motor while being extracted up and down in the measuring cylinder.
[0011] At the same time, the stirring plate itself can be rotated under the drive of the first drive motor. Setting the stirring plate to the rotating mode can not only stir the suspension in the measuring cylinder more evenly, but also keep the stirring plate in a rotating state during the sliding of the stirring plate from one measuring cylinder to the next measuring cylinder. In this state, the soil particles and suspension on the stirring plate will be scattered from the stirring plate under the action of centrifugal force during the rotation of the stirring plate, so that the soil particles and suspension on the stirring plate can be quickly eliminated. At the same time, the stirring plate can be quickly air-dried under the action of wind during the rotation process, so that the stirring plate can be quickly dried before arriving at the next measuring cylinder, further accelerating the speed of eliminating soil particles and suspension on the stirring plate, and effectively ensuring that the stirring plate will not mix the soil particles and suspension in the previous measuring cylinder into the next measuring cylinder before extending into the next measuring cylinder, so as not to affect the results of the soil particle material detection and analysis in the next measuring cylinder.
[0012] Preferably, a second mounting cylinder is provided at the bottom of the first driving motor, the second mounting cylinder is located above the second rotating gear, the second mounting cylinder is hollow inside, a first gear is installed in the second mounting cylinder along the horizontal direction, the first gear is integrally sleeved on the first rotating shaft, one side of the first gear is meshed and connected with the second gear along the vertical direction, the side of the second gear away from the first gear is integrally connected with the second rotating shaft along the horizontal direction, the end of the second rotating shaft away from the second gear is integrally connected with the third gear, the third gear is vertically arranged, the third gear is meshed and connected with a rack along the vertical direction, and the rack is integrally connected to the sliding seat on the mounting frame.
[0013] By adopting the above technical solution, specifically, when the first drive motor drives the first rotating shaft to rotate, the first gear rotates synchronously with the first rotating shaft. During the rotation process, the first gear meshes with the second gear and drives the second gear to rotate. As the second gear rotates, the second rotating shaft starts to rotate and drives the third gear to rotate synchronously. While the third gear rotates, it rises and falls along the length direction of the rack. While the third gear rises and falls, it synchronously drives the first drive motor and the stirring plate to rise and fall.
[0014] The stirring plate is driven to rise and fall by the first drive motor. By adjusting the rotation speed of the first drive motor, the speed of the stirring plate extracting up and down can be adjusted, which is beneficial to increase the overall adaptability of the device, so that it can still work under different detection requirements. At the same time, with this setting, the faster the rotation speed of the first drive motor, the faster the speed of the stirring plate extracting up and down. In this state, it means that the amplitude of stirring the suspension in the measuring cylinder needs to be increased. At the same time, the faster the rotation speed of the first drive motor, the faster the rotation speed of the stirring plate. This makes the stirring plate's rotation speed increase while the speed of extraction up and down increases; the stirring plate's rotation speed slows down while the speed of extraction up and down slows down. This allows the two motion states of the stirring plate to be combined and echoed, which is beneficial to improve the effect of the stirring plate on stirring the suspension in the measuring cylinder.
[0015] Preferably, a liquid leakage prevention plate is additionally provided above the stirring plate. The liquid leakage prevention plate is arranged above the stirring plate in a horizontal direction and is slidably arranged along the length direction of the support rod.
[0016] By adopting the above technical solution, when the stirring plate is extracted up and down in the measuring cylinder to stir the suspension, the suspension in the measuring cylinder will inevitably splash out of the measuring cylinder during the stirring process, resulting in leakage. Leakage will cause the particle content in the soil to decrease, affecting the accuracy of its test results. The anti-leakage plate can block the top of the measuring cylinder during the stirring of the suspension in the measuring cylinder by the stirring plate, thereby effectively preventing the suspension in the measuring cylinder from splashing out of the measuring cylinder during the stirring process.
[0017] Preferably, a lifting seat is provided around the supporting rod, a second driving motor is installed on the top of the lifting seat, the anti-leakage plate is located below the second driving motor, the driving end of the second driving motor faces the anti-leakage plate, and a screw rod is connected between the driving end of the second driving motor and the anti-leakage plate, an internal threaded hole for the screw rod to pass through is provided on the anti-leakage plate, the anti-leakage plate is threadedly connected to the screw rod, and a gap is reserved between the anti-leakage plate and the supporting rod.
[0018] By adopting the above technical solution, specifically, the anti-leakage plate and the support rod are not in a state of close fit, and a small gap is reserved between the anti-leakage plate and the peripheral side of the support rod. The purpose of doing this is that when the stirring plate stirs up and down in the graduated cylinder, the support rod will move up and down together. When the stirring plate stirs up and down in the graduated cylinder, it will be moved down to the bottom of the graduated cylinder before it can be lifted, so as to effectively ensure the effect of stirring the suspension at the bottom of the graduated cylinder. However, if when the stirring plate moves down, before arriving at the bottom of the graduated cylinder, the anti-leakage plate has arrived at the top surface of the suspension in the graduated cylinder. In this state, if the stirring plate continues to move down, the anti-leakage plate will be immersed in the suspension, and the soil particles in the suspension will be taken out of the graduated cylinder.
[0019] In this case, the stirring plate needs to continue to move down, while the anti-leakage plate needs to move up. When the stirring plate moves down, the support rod moves down with the stirring plate. Therefore, the anti-leakage plate and the support rod cannot be connected. A certain gap needs to be reserved to separate the anti-leakage plate and the support rod to avoid the problem of motion interference between the two in the above situation.
[0020] In summary: after the stirring plate enters the measuring cylinder, its range of up and down movement is from the bottom of the measuring cylinder to the top of the suspension; the range of movement of the anti-leakage plate is from the top of the suspension to the top of the measuring cylinder. When the anti-leakage plate is about to be immersed in the suspension as the stirring plate moves downward, the screw rod is driven to rotate by the second driving motor, and the anti-leakage plate rises during the rotation of the screw rod, thereby effectively ensuring that the position of the anti-leakage plate is always above the top of the suspension.
[0021] Preferably, the support rod is provided with a sliding section for the lifting seat to adjust the position, the sliding section is in the shape of an external thread, the inner side of the lifting seat is an internal thread section, and the lifting seat is threadedly connected to the sliding section.
[0022] By adopting the above technical solution, the distance between the second drive motor and the stirring plate can be adaptively adjusted according to the height of the measuring cylinder. When the second drive motor moves down with the stirring plate, if the stirring plate has not reached the bottom surface of the measuring cylinder, and the second drive motor has approached the top surface of the measuring cylinder, in this state, the stirring plate needs to continue to move down, and the second drive motor cannot continue to move down. At this time, the second drive motor is slid upward on the support rod to adjust the position of the second drive motor.
[0023] Preferably, a positioning seat for fixing the measuring cylinder is fixed on the placement table in the horizontal direction.
[0024] By adopting the above technical solution, the measuring cylinder is effectively positioned by using the positioning seat, so that the measuring cylinder can maintain sufficient stability while the stirring plate stirs the suspension in the measuring cylinder.
[0025] Preferably, a clamp is added in the horizontal direction inside the positioning seat, and the clamp includes three clamping rods, which are all installed on the inner wall of the positioning seat in the horizontal direction, and the three clamping rods are clamped and distributed on the circumference of the measuring cylinder; the three clamping rods are slidably arranged in the positioning seat in a direction of approaching or moving away from each other;
[0026] The ends of the three clamping rods are connected to the inner wall of the positioning seat through torsion springs, and the ends of the three clamping rods away from the torsion springs are connected to each other; the sides of the three clamping rods that are close to each other are bent in an arc shape in a direction away from each other.
[0027] By adopting the above technical solution, the three clamping rods are slidably arranged in the positioning seat in the direction of approaching or moving away from each other, so that the inner diameter of the cavity between the three clamping rods can be adjusted. When measuring cylinders of different specifications and models are inserted into the positioning seat, the inner diameter of the cavity between the three clamping rods is adaptively adjusted according to the specifications and models of the measuring cylinders, further increasing the overall adaptability of the positioning seat.
[0028] Specifically, the ends of the three clamping rods are connected to the inner wall of the positioning seat through torsion springs, and the ends of the three clamping rods away from the torsion springs are connected to each other. The torsion springs are used to hinge the three clamping rods to the inner wall of the positioning seat, so that the clamping rods can rotate horizontally in the positioning seat.
[0029] When the outer diameter of the measuring cylinder increases, the surrounding side of the measuring cylinder squeezes the three clamping rods at the same time during the insertion of the measuring cylinder into the three clamping rods. Driven by the torsion spring, the three clamping rods rotate in the direction away from each other. In this state, the inner diameter of the chamber between the three clamping rods increases accordingly, and can effectively adapt to the measuring cylinder with an increased outer diameter. Similarly, when the outer diameter of the measuring cylinder decreases, the three clamping rods also rotate in the direction of approaching each other under the drive of the torsion spring. In this state, the inner diameter of the chamber between the three clamping rods decreases.
[0030] The side where the clamping rods are close to each other is set to a curved arc shape. When clamping and positioning the peripheral side of the measuring cylinder, the side wall of the clamping rod and the peripheral side of the measuring cylinder can fit more closely, which is beneficial to improve the effect of clamping and positioning the measuring cylinder by the three clamping rods.
[0031] In summary, the present application includes at least one of the following beneficial technical effects:
[0032] 1. When the stirring plate slides from the measuring cylinder to the next measuring cylinder after stirring, the hydrometer can be inserted into the measuring cylinder that has just been stirred to perform buoyancy detection. As the stirring plate stirs in the next measuring cylinder, the hydrometer can complete the buoyancy detection and analysis of the previous measuring cylinder. Similarly, while the stirring plate is stirring the suspension in the next measuring cylinder, the hydrometer can simultaneously perform buoyancy detection and analysis on the suspension in the previous measuring cylinder, thereby optimizing the soil material test analysis process and significantly improving the convenience and test efficiency of soil material test analysis;
[0033] The stirring plate can rotate while stirring the suspension in the measuring cylinder. This allows the stirring plate to not only stir the suspension in the measuring cylinder by pulling it up and down, but also to increase the amplitude of stirring the suspension in the measuring cylinder by its own rotation during the process of pulling it up and down. This allows the stirring plate to stir the suspension in the measuring cylinder more evenly. For suspensions containing solid particles, increasing the stirring amplitude while stirring evenly can effectively prevent the solid particles from settling and maintain the stability of the suspension, thereby improving the accuracy of the test analysis results of soil materials.
[0034] 2. The stirring plate itself can rotate under the drive of the first drive motor. Setting the stirring plate to the rotating mode can not only stir the suspension in the measuring cylinder more evenly, but also keep the stirring plate in a rotating state during the process of sliding from one measuring cylinder to the next measuring cylinder. In this state, the soil particles and suspension on the stirring plate will be scattered from the stirring plate under the action of centrifugal force during the rotation of the stirring plate, so that the soil particles and suspension on the stirring plate can be quickly eliminated. At the same time, during the rotation of the stirring plate, the stirring plate can be quickly air-dried under the action of wind, so that the stirring plate can be quickly dried before reaching the next measuring cylinder, further speeding up the elimination of soil particles and suspension on the stirring plate, and effectively ensuring that the stirring plate will not mix the soil particles and suspension in the previous measuring cylinder into the next measuring cylinder before extending into the next measuring cylinder, thereby not affecting the results of the soil particle material detection and analysis in the next measuring cylinder;
[0035] 3. When the stirring plate moves up and down in the measuring cylinder to stir the suspension, the suspension in the measuring cylinder will inevitably splash out of the measuring cylinder during the stirring process, resulting in leakage. Leakage will reduce the particle content in the soil and affect the accuracy of the test results. The anti-leakage plate can block the top of the measuring cylinder when the stirring plate stirs the suspension in the measuring cylinder, thereby effectively preventing the suspension in the measuring cylinder from splashing out of the measuring cylinder during the stirring process.

DETAILED DESCRIPTION
[0042] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.
[0043] Example:
[0044] The present application discloses a convenient and efficient soil particle test analysis device, referring to Figure 1 and Figure 2 , including a mounting frame 1 and a placing table 2. The mounting frame 1 is welded into a square frame structure by a plurality of horizontal bars and vertical bars. The placing table 2 is welded to the bottom of the mounting frame 1, and the measuring cylinder is vertically fixed on the placing table 2. The mounting frame 1 is provided with a stirring plate 3 and a hydrometer 4. The stirring plate 3 is used to stir the suspension in the measuring cylinder. After the stirring plate 3 stirs the suspension in the measuring cylinder, the hydrometer 4 is inserted into the measuring cylinder, and the suspension in the measuring cylinder after stirring is detected and analyzed by the hydrometer 4.
[0045] The corresponding stirring plate 3 and the hydrometer 4 can slide on the mounting frame 1 along the three directions of X, Y, and Z, and the stirring plate 3 and the hydrometer 4 are spaced apart in the horizontal direction, and the spacing between the stirring plate 3 and the hydrometer 4 is consistent with the spacing between two adjacent measuring cylinders. When the stirring plate 3 slides from the stirring in the measuring cylinder to the stirring in the next measuring cylinder, the hydrometer 4 can extend into the measuring cylinder that has just been stirred to perform buoyancy detection. As the stirring plate 3 stirs in the next measuring cylinder, during this process, the hydrometer 4 can complete the detection and analysis of the buoyancy in the previous measuring cylinder. By analogy, while the stirring plate 3 stirs the suspension in the next measuring cylinder, the hydrometer 4 can simultaneously perform buoyancy detection and analysis on the suspension in the previous measuring cylinder, thereby optimizing the soil material test analysis process, and significantly improving the convenience and test efficiency of soil material test analysis.
[0046] In this embodiment, the stirring plate 3 can rotate itself while stirring the suspension by extracting it up and down in the measuring cylinder. This allows the stirring plate 3 to not only stir the suspension in the measuring cylinder by extracting it up and down, but also to increase the amplitude of stirring the suspension in the measuring cylinder by its own rotation during the extraction process. This allows the stirring plate 3 to stir the suspension in the measuring cylinder more evenly. For suspensions containing solid particles, increasing the stirring amplitude while stirring evenly can effectively prevent the solid particles from settling, maintain the stability of the suspension, and thus improve the accuracy of the soil material test analysis results.
[0047] In this embodiment, the sliding of the stirring plate 3 and the hydrometer 4 along the X and Y directions are driven by a motor installed on the mounting frame 1. A corresponding sliding seat is fixed on the top of the mounting frame 1, and the motor drives the stirring plate 3 and the hydrometer 4 to slide on the sliding seat.
[0048] Specifically, the stirring plate 3 is gear-shaped as a whole and is arranged horizontally. A support rod is installed on the top of the stirring plate 3 in the vertical direction, and the hydrometer 4 is connected to the support rod through a corresponding connecting rod and a connecting plate.
[0049] Reference Figure 1 , Figure 2 as well as Figure 3 , a first mounting cylinder 5 with a hollow interior is installed at the bottom of the support rod. The top of the stirring plate 3 is connected to a first rotating gear 6 in a horizontal direction, and the stirring plate 3 extends from the bottom of the first mounting cylinder 5, and the first rotating gear 6 is located in the first mounting cylinder 5. At the same time, a linkage gear 7 is vertically arranged in the first mounting cylinder 5, and the bottom of the linkage gear 7 is meshed and connected with the first rotating gear 6, and the top of the linkage gear 7 is meshed and connected with a second rotating gear 8. The end of the second rotating gear 8 away from the linkage gear 7 is connected to a first rotating shaft 9 in a vertical direction, and the top of the first rotating shaft 9 extends upward from the support rod and is connected to a first driving motor 10.
[0050] A support seat for placing the first drive motor 10 is welded to the side wall of the sliding seat on the mounting frame 1. The first drive motor 10 is installed on the support seat. The first drive motor 10 slides in the horizontal direction under the drive of the sliding seat.
[0051] Specifically, when the stirring plate 3 is extending downward into the measuring cylinder, the first drive motor 10 is turned on, and the first rotating shaft 9 is driven by the first drive motor 10 to rotate. The first rotating shaft 9 drives the second rotating gear 8 to rotate during the rotation process, and the second rotating gear 8 is meshed with the linkage gear 7 during the rotation process, thereby driving the linkage gear 7 to rotate. After the linkage gear 7 rotates, it meshes with the first rotating gear 6, and then drives the stirring plate 3 to rotate in the horizontal direction through the linkage gear 7. In this state, the stirring plate 3 is driven by the first drive motor 10 while extracting up and down in the measuring cylinder. After the stirring plate 3 completes stirring of the suspension in the measuring cylinder, it slides to the next measuring cylinder to continue stirring.
[0052] The measuring cylinders on the placement table 2 are placed at a certain distance from each other. The purpose of this is that when the stirring plate 3 completes stirring in the measuring cylinder, when the stirring plate 3 is extended from the measuring cylinder, some soil particles and suspension in the measuring cylinder will inevitably be adsorbed on the stirring plate 3. If the stirring plate 3 in this state is immediately extended into the next measuring cylinder for stirring, the soil particles and suspension in the previous measuring cylinder will be mixed into the next measuring cylinder, thereby affecting the content of the soil particles in the next measuring cylinder, and further affecting the results of the soil particle material detection and analysis in the next measuring cylinder.
[0053] It should be noted here that the distance between the stirring plate 3 sliding from the previous measuring cylinder to the next measuring cylinder is set in advance by the control box system according to the distance between two adjacent measuring cylinders. When the stirring plate 3 slides from the previous measuring cylinder to the next measuring cylinder, the stirring plate 3 and the hydrometer 4 are moved forward by the sliding seat on the mounting frame. Here, the stirring plate 3 and the hydrometer 4 are moved forward by the sliding seat, which is a prior art and will not be described in detail.
[0054] In order to avoid the above situation, the conventional practice is to space adjacent measuring cylinders by a certain distance, so that after the stirring plate 3 comes out of a measuring cylinder, it needs to slide for a distance before it can reach the top of the next measuring cylinder. In the process of the stirring plate 3 sliding from the previous measuring cylinder to the next measuring cylinder, the soil particles on the stirring plate 3 will slowly slide off the stirring plate 3 along with the suspension, and then when the stirring plate 3 slides into the next measuring cylinder, the soil particles and suspension in the previous measuring cylinder will not be mixed into the next measuring cylinder, and thus will not affect the results of the soil particle material detection and analysis in the next measuring cylinder.
[0055] However, since the space of the placement table 2 is limited, the interval between two adjacent measuring cylinders is also limited, even a very short distance. Such a short distance is difficult to ensure that the suspension on the stirring plate 3 can slide off completely. In actual operation, it is found that it is difficult for the suspension on the stirring plate 3 to completely slide off the stirring plate 3 when sliding to the next measuring cylinder. This makes the effect of the suspension on the stirring plate 3 falling off very poor. When the stirring plate 3 is extended into the next measuring cylinder for stirring, it will still affect the results of the soil particle material detection and analysis in the next measuring cylinder.
[0056] In this embodiment, the stirring plate 3 itself can be rotated under the drive of the first drive motor 10. Setting the stirring plate 3 to the rotating mode can not only stir the suspension in the measuring cylinder more evenly, but also keep the stirring plate 3 in a rotating state during the sliding of the stirring plate 3 from one measuring cylinder to the next measuring cylinder. In this state, the soil particles and suspension on the stirring plate 3 will be scattered from the stirring plate 3 under the action of centrifugal force during the rotation of the stirring plate 3, so that the soil particles and suspension on the stirring plate 3 can be quickly eliminated. At the same time, the stirring plate 3 can be quickly air-dried under the action of wind during the rotation process, so that the stirring plate 3 can be quickly dried before reaching the next measuring cylinder, further accelerating the speed of eliminating the soil particles and suspension on the stirring plate 3, and effectively ensuring that the stirring plate 3 will not mix the soil particles and suspension in the previous measuring cylinder into the next measuring cylinder before extending into the next measuring cylinder, so as not to affect the results of the soil particle material detection and analysis in the next measuring cylinder.
[0057] Specifically, refer to Figure 2 , Figure 3 as well as Figure 4 A second mounting tube 11 is provided at the bottom of the first driving motor 10, and the second mounting tube 11 is located above the second rotating gear 8. The second mounting tube 11 is hollow inside, and a first gear 12 is installed in the second mounting tube 11 along the horizontal direction. The first gear 12 is integrally sleeved on the first rotating shaft 9, and one side of the first gear 12 is meshed and connected with a second gear 13 along the vertical direction, and the side of the second gear 13 away from the first gear 12 is integrally connected with a second rotating shaft 14 along the horizontal direction, and the end of the second rotating shaft 14 away from the second gear 13 extends out a support rod and is integrally connected with a third gear 15, and the third gear 15 is vertically arranged. The third gear 15 is meshed and connected with a rack 16 along the vertical direction. Refer to Figure 1 and Figure 2 The rack 16 is integrally connected with the sliding seat on the mounting frame 1.
[0058] Specifically, when the first drive motor 10 drives the first rotating shaft 9 to rotate, the first gear 12 rotates synchronously with the first rotating shaft 9. During the rotation process, the first gear 12 meshes with the second gear 13 and drives the second gear 13 to rotate. As the second gear 13 rotates, the second rotating shaft 14 starts to rotate and drives the third gear 15 to rotate synchronously. While the third gear 15 rotates, it rises and falls along the length direction of the rack 16. While the third gear 15 rises and falls, it synchronously drives the first drive motor 10 and the stirring plate 3 to rise and fall.
[0059] The stirring plate 3 is driven to rise and fall by the first drive motor 10. By adjusting the rotation speed of the first drive motor 10, the speed of the stirring plate 3 extracting up and down can be adjusted, which is conducive to increasing the adaptability of the device as a whole, so that it can still work under different detection requirements. At the same time, in this setting mode, the faster the rotation speed of the first drive motor 10, the faster the speed of the stirring plate 3 extracting up and down. In this state, it is necessary to increase the amplitude of stirring the suspension in the measuring cylinder. At the same time, the faster the rotation speed of the first drive motor 10, the faster the rotation speed of the stirring plate 3. This makes the stirring plate 3 speed up while the extraction speed becomes faster; the stirring plate 3 slows down while the extraction speed becomes slower. Then, the two motion states of the stirring plate 3 can be combined and echoed, which is conducive to improving the effect of the stirring plate 3 stirring the suspension in the measuring cylinder.
[0060] Further, refer to Figure 2 and Figure 3 A liquid leakage prevention plate 17 is provided above the stirring plate 3. The liquid leakage prevention plate 17 is annular and is arranged above the stirring plate 3 in the horizontal direction and is slidably arranged along the length direction of the support rod.
[0061] When the stirring plate 3 is pulled up and down in the measuring cylinder to stir the suspension, the suspension in the measuring cylinder will inevitably splash out of the measuring cylinder during the stirring process, resulting in leakage. Leakage will cause the particle content in the soil to decrease, affecting the accuracy of its test results. The anti-leakage plate 17 can block the top of the measuring cylinder during the stirring of the suspension in the measuring cylinder by the stirring plate 3, thereby effectively preventing the suspension in the measuring cylinder from splashing out of the measuring cylinder during the stirring process.
[0062] Specifically, refer to Figure 2 A lifting seat 18 is sleeved around the support rod, a second drive motor 19 is installed on the top of the lifting seat 18, the anti-leakage plate 17 is located below the second drive motor 19, the driving end of the second drive motor 19 faces the anti-leakage plate 17, and a screw rod 20 is connected between the driving end of the second drive motor 19 and the anti-leakage plate 17. An internal threaded hole for the screw rod 20 to penetrate is provided on the anti-leakage plate 17, and the anti-leakage plate 17 and the screw rod 20 are set to be threadedly connected through the internal threaded hole.
[0063] Specifically, the anti-leakage plate 17 is not in a state of close fit with the support rod, and a small gap is reserved between the anti-leakage plate 17 and the support rod circumference. The purpose of doing this is that when the stirring plate 3 stirs up and down in the graduated cylinder, the support rod will move up and down together. When the stirring plate 3 stirs up and down in the graduated cylinder, it will move down to the bottom of the graduated cylinder before it can be lifted, so as to effectively ensure the effect of stirring the suspension at the bottom of the graduated cylinder. However, if when the stirring plate 3 moves down, before arriving at the bottom of the graduated cylinder, the anti-leakage plate 17 has arrived at the top surface of the suspension in the graduated cylinder. In this state, if the stirring plate 3 continues to move down, the anti-leakage plate 17 will immerse in the suspension, and the soil particles in the suspension will be taken out of the graduated cylinder.
[0064] In this case, the stirring plate 3 needs to continue to move downward, and the anti-leakage plate 17 needs to move upward. When the stirring plate 3 moves downward, the support rod moves downward with the stirring plate 3. Therefore, the anti-leakage plate 17 and the support rod cannot be connected. A certain gap needs to be reserved to separate the anti-leakage plate 17 and the support rod to avoid the problem of motion interference between the two in the above situation.
[0065] In summary, after the stirring plate 3 enters the measuring cylinder, its range of upward and downward movement is from the bottom surface of the measuring cylinder to the top surface of the suspension; the range of movement of the anti-leakage plate 17 is from the top surface of the suspension to the top surface of the measuring cylinder. When the anti-leakage plate 17 is about to be immersed in the suspension as the stirring plate 3 moves downward, the screw rod 20 is driven to rotate by the second driving motor 19, and the anti-leakage plate 17 rises during the rotation process, thereby effectively ensuring that the position of the anti-leakage plate 17 is always above the top surface of the suspension.
[0066] Furthermore, the lifting seat 18 is slidably arranged along the length direction of the support rod. This allows the distance between the second drive motor 19 and the stirring plate 3 to be adaptively adjusted according to the height of the measuring cylinder. When the second drive motor 19 moves down with the stirring plate 3, if the stirring plate 3 has not yet reached the bottom surface of the measuring cylinder, and the second drive motor 19 has approached the top surface of the measuring cylinder, in this state, the stirring plate 3 needs to continue to move down, and the second drive motor 19 cannot continue to move down. At this time, slide the second drive motor 19 upward on the support rod to adjust the position of the second drive motor 19.
[0067] Specifically, refer to Figure 2 The support rod is provided with a sliding section 21 for adjusting the position of the lifting seat 18, and the lifting seat 18 can adjust its position on the sliding section 21. The sliding section 21 is externally threaded, and the inner side of the lifting seat 18 is an internally threaded section. The lifting seat 18 is threadedly connected to the sliding section 21 on the support rod.
[0068] Specifically, during assembly, the distance between the lifting seat 18 and the stirring plate 3 needs to be designed and planned in advance according to the height of the measuring cylinder, so as to effectively avoid the second drive motor 19 still failing to meet the position requirement after sliding to the maximum distance on the sliding section 21.
[0069] Further, refer to Figure 1 and Figure 2 A positioning seat 22 for fixing the measuring cylinder is welded horizontally on the placing table 2. The measuring cylinder is effectively positioned by the positioning seat 22, so that the measuring cylinder can maintain sufficient stability while the stirring plate 3 stirs the suspension in the measuring cylinder.
[0070] Specifically, refer to Figure 1 and Figure 5 The positioning seat 22 is disc-shaped and welded on the placing table 2. A clamp 23 is provided in the positioning seat 22 in the horizontal direction, and the clamp 23 is used to clamp and position the bottom of the measuring cylinder.
[0071] Specifically, refer to Figure 5 The fixture 23 includes three clamping rods 231, which are all installed on the inner wall of the positioning seat 22 in the horizontal direction. The three clamping rods 231 are connected end to end, so that a hollow chamber is formed in the middle of the three clamping rods 231. After the measuring cylinder is inserted into the positioning seat 22, the bottom of the measuring cylinder is located in the chamber between the three clamping rods 231. The three clamping rods 231 are clamped and distributed on the peripheral side of the measuring cylinder, and the bottom of the measuring cylinder is clamped and positioned by the three clamping rods 231. At the same time, the three clamping rods 231 are slidably arranged in the positioning seat 22 in the direction of approaching or moving away from each other, which makes the inner diameter of the middle chamber of the three clamping rods 231 adjustable. When measuring cylinders of different specifications and models are inserted into the positioning seat 22, the inner diameter of the chamber between the three clamping rods 231 is adaptively adjusted according to the specifications and models of the measuring cylinder, further increasing the overall adaptability of the positioning seat 22.
[0072] Specifically, the ends of the three clamping rods 231 are connected to the inner wall of the positioning seat 22 through torsion springs, and the ends of the three clamping rods 231 away from the torsion springs are connected to each other. The torsion springs are used to hinge the three clamping rods 231 to the inner wall of the positioning seat 22, so that the clamping rods 231 can rotate in the positioning seat 22 along the horizontal direction.
[0073] When the outer diameter of the measuring cylinder increases, the surrounding side of the measuring cylinder squeezes the three clamping rods 231 at the same time during the process of inserting the measuring cylinder into the three clamping rods 231, and the three clamping rods 231 rotate in the direction away from each other under the drive of the torsion spring. In this state, the inner diameter of the chamber between the three clamping rods 231 increases accordingly, and can effectively adapt to the measuring cylinder with an increased outer diameter. Similarly, when the outer diameter of the measuring cylinder decreases, the three clamping rods 231 also rotate in the direction of approaching each other under the drive of the torsion spring, and in this state, the inner diameter of the chamber between the three clamping rods 231 decreases.
[0074] In this embodiment, the sides of the three clamping rods 231 that are close to each other are bent in an arc shape in the direction of moving away from each other. The sides of the clamping rods 231 that are close to each other are set to a curved arc shape. When the peripheral side of the measuring cylinder is clamped and positioned, the side walls of the clamping rods 231 and the peripheral side of the measuring cylinder can fit more closely, which is beneficial to improve the effect of the three clamping rods 231 on clamping and positioning the measuring cylinder.
[0075] The implementation principle of a convenient and efficient soil particle test analysis device in the embodiment of the present application is:
[0076] The stirring plate 3 can rotate itself while stirring the suspension by extracting it up and down in the measuring cylinder. This allows the stirring plate 3 to not only stir the suspension in the measuring cylinder by extracting it up and down, but also to increase the amplitude of stirring the suspension in the measuring cylinder by its own rotation during the extraction process. This allows the stirring plate 3 to stir the suspension in the measuring cylinder more evenly. For suspensions containing solid particles, increasing the stirring amplitude while stirring evenly can effectively prevent the solid particles from settling, maintain the stability of the suspension, and thus improve the accuracy of the test analysis results of soil materials.
[0077] After the stirring plate 3 enters the measuring cylinder, the range of its upward and downward movement is from the bottom surface of the measuring cylinder to the top surface of the suspension; the range of movement of the anti-leakage plate 17 is from the top surface of the suspension to the top surface of the measuring cylinder. When the anti-leakage plate 17 is about to be immersed in the suspension as the stirring plate 3 moves downward, the screw rod 20 is driven to rotate by the second drive motor 19, and the screw rod 20 rises during the rotation process, thereby effectively ensuring that the position of the anti-leakage plate 17 is always above the top surface of the suspension. The anti-leakage plate 17 can block the top of the measuring cylinder during the stirring process of the suspension in the measuring cylinder by the stirring plate 3, thereby effectively preventing the suspension in the measuring cylinder from splashing out of the measuring cylinder during the stirring process.
[0078] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
