Description

Technical Field

[0001] This utility model belongs to the field of soil mechanical composition analysis technology, and in particular relates to an unattended testing sedimentation cylinder device for soil mechanical composition. Background Technology

[0002] Soil mechanical composition, namely the relative content of mineral particles of different sizes in the soil, plays a decisive role in the basic properties, fertility level, and many practical applications of soil. From the perspective of agricultural production, it affects the soil's water and fertilizer retention, aeration, and permeability, which in turn affects crop growth and yield. For example, sandy soil has good aeration but poor water retention, while clay soil has the opposite. Accurate understanding of soil mechanical composition is the basis for rational fertilization, irrigation, and seed selection. In the field of ecological environment, it participates in the process of soil erosion and degradation, affects the migration and transformation of pollutants, and is a key indicator for assessing the effectiveness of ecological restoration and monitoring environmental changes. In terms of engineering construction, soil mechanical composition determines the bearing capacity and stability of the foundation, which is of great significance to the construction of infrastructure such as roads and buildings.

[0003] Existing methods for detecting soil mechanical composition, such as the pipette method and hydrometer method, require manual operation, which is time-consuming, inefficient, and prone to large human reading errors. The traditional hydrometer method requires manual recording of readings at different time points multiple times and is affected by factors such as temperature and light, making it difficult to achieve continuous monitoring and automation. Therefore, an unattended soil mechanical composition testing sedimentation tank device is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide an unattended testing sedimentation cylinder device for soil machinery components, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The soil machinery assembly includes an unattended testing sedimentation cylinder device, comprising a workbench, a base connected to the top of the workbench, a sedimentation cylinder connected to the top of the base, a top cover movably connected to the top of the sedimentation cylinder, a mixing assembly connected inside the sedimentation cylinder, an electric telescopic rod connected to the top of one side of the workbench, a connecting frame connected to the top of the electric telescopic rod, and a densitometer connected to one end of the connecting frame.

[0007] The stirring assembly includes a motor, the output end of which is connected to a connecting shaft, and a stirring rod is connected to the outside of the connecting shaft. Heating wires are connected through the inside of both the connecting shaft and the stirring rod, and scrapers are connected to the outside of both ends of the connecting shaft.

[0008] A further technical solution is that a fill light is connected to the bottom of the top cover, a camera is connected through the middle of the top cover, and a controller is connected to the top of the top cover. The controller is connected to the fill light and the camera via wires.

[0009] A further technical solution is that an injection port is connected through the top of one side of the top cover, and the top of the other side of the top cover is connected through the connecting frame, which is L-shaped.

[0010] In a further technical solution, the densitometer has a display screen on top, which is located below the camera, and a detection probe is connected to the bottom of the densitometer.

[0011] In a further technical solution, the number of scrapers is two, and one side of each scraper is slidably connected to the inner wall of the settling cylinder.

[0012] In a further technical solution, the motor is located inside the base, a temperature sensor is embedded in the bottom of the settling cylinder, and the settling cylinder is made of transparent material.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, through the collaboration of an electric telescopic rod and an L-shaped connecting frame, can automatically control the lifting and lowering of the densitometer, eliminating the need for manual hand-holding or adjustment of the densitometer's position. This solves the tedious operation of repeated manual placement and reading of the densitometer using traditional hydrometers. At the same time, the motor-driven connecting shaft and stirring rod of the mixing component automatically stir the soil suspension, replacing manual stirring and avoiding the problems of uneven stirring force and inaccurate time control. The camera integrated in the top cover, together with the supplementary light, can automatically capture the data displayed on the top of the densitometer. Combined with the controller's automatic data acquisition function, there is no need for manual recording of readings at different time points, achieving fully unmanned operation without intervention after startup.

[0015] In this invention, a temperature sensor embedded at the bottom of the settling cylinder can monitor the suspension temperature in real time. The heating wire running through the connecting shaft of the stirring assembly and the stirring rod can adjust the suspension temperature according to the feedback from the temperature sensor, solving the problem that room temperature fluctuations affect the side-view results in traditional tests and further ensuring the accuracy of the test results. The scrapers on both sides of the stirring assembly are slidably connected to the inner wall of the settling cylinder, which can scrape off the soil particles attached to the inner wall of the settling cylinder in real time during the stirring process, avoiding the problem of inaccurate suspension concentration caused by particles adhering to the cylinder wall in traditional tests.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] like Figures 1-5 As shown, this utility model embodiment provides an unattended testing sedimentation cylinder device for soil machinery, including a workbench 1, a base 2 connected to the top of the workbench 1, a sedimentation cylinder 3 connected to the top of the base 2, a top cover movably connected to the top of the sedimentation cylinder 3, a stirring assembly 4 connected inside the sedimentation cylinder 3, an electric telescopic rod 5 connected to the top of one side of the workbench 1, a connecting frame 6 connected to the top of the electric telescopic rod 5, and a densitometer 7 connected to one end of the connecting frame 6.

[0026] The stirring assembly 4 includes a motor 401, the output end of the motor 401 is connected to a connecting shaft 402, the outside of the connecting shaft 402 is connected to a stirring rod 403, and heating wires 404 are connected through the inside of both the connecting shaft 402 and the stirring rod 403. Scrapers 405 are connected to the outside of both ends of the connecting shaft 402.

[0027] In this embodiment, the motor 401 is started, driving the connecting shaft 402 and the stirring rod 403 to rotate at high speed, so that the soil particles and water are fully mixed to form a uniform suspension. At the same time, the heating wire 404 inside the connecting shaft 402 and the stirring rod 403 automatically adjusts the heating power through the controller 12 according to the temperature data fed back in real time by the temperature sensor 14 at the bottom of the settling cylinder 3, so as to stabilize the temperature of the suspension at 20±0.5℃ (the standard application temperature of Stokes' Law), so as to avoid temperature fluctuations causing changes in liquid viscosity and affecting the particle settling speed. After the suspension is evenly stirred, the motor 401 stops running, and the soil particles begin to settle in layers according to particle size. The electric telescopic rod 5 drives the L-shaped connecting frame 6 to slowly lower the densitometer 7 according to the preset parameters of the controller 12, so that the detection probe 9 at the bottom of the densitometer 7 is accurately inserted into the suspension at a specified depth.

[0028] like Figure 3 , Figure 4 and Figure 5 As shown, specifically, a fill light 11 is connected to the bottom of the top cover, a camera 10 is connected through the middle of the top cover, and a controller 12 is connected to the top of the top cover. The controller 12 is connected to the fill light 11 and the camera 10 through wires.

[0029] One side of the top of the top cover has a through-hole 13, and the other side of the top of the top cover is connected to the connecting frame 6, which is L-shaped.

[0030] The top of the densitometer 7 is equipped with a display screen 8, which is located below the camera 10. The bottom of the densitometer 7 is connected to a detection probe 9.

[0031] There are two scrapers 405, and one side of each scraper 405 is slidably connected to the inner wall of the settling cylinder 3.

[0032] The motor 401 is located inside the base 2, and the temperature sensor 14 is embedded in the bottom of the settling cylinder 3. The settling cylinder 3 is made of transparent material.

[0033] In this embodiment, the densitometer 7 measures the density of the suspension at different time points in real time through the detection probe 9 and displays the density data on the top display screen 8 in real time. The supplementary light 11 at the bottom of the top cover is turned on, and the camera 10 is aimed at the display screen 8. The camera automatically captures the display screen data at preset time intervals, such as 1min, 5min, 30min, 2h, and 24h, which can be adjusted according to the test requirements. The image information is transmitted to the controller 12. When the scraper 405 at both ends of the connecting shaft 402 rotates with the connecting shaft 402, it slides and contacts the inner wall of the transparent settling cylinder 3, scraping off the soil particles attached to the cylinder wall in real time, avoiding the deviation of the suspension concentration measurement caused by particle adhesion.

[0034] The working principle of this utility model is as follows: First, after pretreatment, the soil sample is injected into the settling cylinder 3 through the injection port 13 on the top cover, and a quantitative amount of distilled water is added to bring the volume to the standard volume. Then, the motor 401 is started, and the motor 401 drives the connecting shaft 402 and the stirring rod 403 to rotate at high speed, so that the soil particles and water are fully mixed to form a uniform suspension. At the same time, the heating wire 404 inside the connecting shaft 402 and the stirring rod 403 automatically adjusts the heating power through the controller 12 according to the temperature data fed back in real time by the temperature sensor 14 at the bottom of the settling cylinder 3, so as to stabilize the suspension temperature at 20±0.5℃. Finally, after the suspension is stirred evenly, the motor 401 stops running, and the soil particles begin to settle in layers according to their particle size. The electric telescopic rod 5 is driven by the controller 12 according to the preset parameters. The connecting frame 6 drives the densitometer 7 to descend slowly, so that the detection probe 9 at the bottom of the densitometer 7 is precisely inserted into the suspension at a specified depth. The densitometer 7 measures the density of the suspension at different time points in real time through the detection probe 9 and displays the density data on the display screen 8 on the top in real time. The supplementary light 11 at the bottom of the top cover is turned on, and the camera 10 is aimed at the display screen 8. At preset time intervals, it automatically captures the display screen data and transmits the image information to the controller 12.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
