Description

Technical Field

[0001] The invention relates to the technical field of sand and gravel testing, in particular to a full-automatic sand equivalent testing instrument. Background Art

[0002] Sand equivalent measures the amount of clay or impurities contained in various fine aggregates, such as natural sand, manufactured sand, and stone chips, to assess the aggregate's cleanliness. In recent years, with the increasing mileage of high-grade highway construction, the demand for aggregate has also increased. Excessive mud and dust in fine aggregate can lead to insufficient adhesion between asphalt, aggregate, and mineral powder, which in turn reduces the high-temperature performance of the asphalt mixture, making it more susceptible to defects such as rutting and pushing, shortening the service life of flexible pavement. Therefore, sand equivalent testing is particularly important.

[0003] Patent No. CN219799450U A new sand equivalent instrument that is easy to install and realizes intelligent It is convenient to adjust the levelness and improve the efficiency of fastening and installation, but it requires manual material replacement, water injection, installation and manual monitoring; Patent No. CN215066671U is a sand equivalent tester for highway inspection that is easy to clean the test tube. When the inner wall of the test tube body needs to be cleaned, the disc is pushed by the T-shaped rod to move the annular scraper. During the movement of the annular scraper, most of the material adhering to the inner wall of the test tube body will be scraped off, and the scraped material will be poured out. At this time, the test tube body is rinsed to facilitate the cleaning of the material contaminated on the inner wall of the test tube. The shortcomings are that it also requires manual operation, monitoring of experimental data and manual testing.

[0004] Therefore, there are some deficiencies in the existing sand equivalent instrument test process: 1. Manual monitoring is required, and manual operation will cause test errors, reducing the efficiency and accuracy of sand equivalent testing; 2. The existing sand equivalent tester has a simple structure, is not convenient for the operation of the overall test, and has a low degree of intelligence. Summary of the Invention

[0019] To facilitate manual loading, a loading device 2 is provided on the housing 1. Loading is performed manually after precise measurement. The loading device 2 comprises an interconnected loading hopper 16 and a discharge pipe 17. A movable opening 18 for moving the discharge pipe 17 is provided on the front wall of the housing 1. When the discharge pipe 17 is moved to either end of the movable opening 18, material is fed into test cylinder 1 6 and test cylinder 2 7, respectively. In this embodiment, the movable opening 18 is arranged at an angle. Specifically, the position of the movable opening 18 matches the position of test cylinder 1 6 and test cylinder 2 7. To facilitate manual movement of the discharge pipe 17, a rubber sleeve may be provided at the contact portion between the discharge pipe 17 and the movable opening 18.

[0020] like Figure 3 As shown, in order to realize the movement of the test cylinder 1 6 and the test cylinder 2 7, they are moved to the corresponding liquid pipe 1 8, liquid pipe 2 9 and discharge pipe 17 respectively, and to realize the oscillation of the test cylinder 1 6 and the test cylinder 2 7, a driving mechanism 1 is set. In order to facilitate installation, a mounting plate 19 is provided in the box body 1. The lower part of the mounting plate 19 is provided with two linear guide rails 20 connected to the test cylinder 1 6 and the test cylinder 2 7 in parallel. A slide groove 21 located on the mounting plate 19 is provided between the two linear guide rails 20. The moving parts include a motor 22, a turntable 23, a driving rod 24 and a connecting rod 25 which are arranged behind the mounting plate 19 and connected in sequence. Figure 9As shown, the connecting rod 25 includes a connecting rod 42 passing through the slide groove 21 and a connecting plate 43 connecting the test cylinder 1 6 and the test cylinder 2 7. Slide blocks are provided between the connecting plate 43 and the two linear guide rails 20; there are two rotating parts, which are respectively arranged between the test cylinder 1 6 and the test cylinder 2 7 and the connecting plate 43, including a motor and a rotating shaft. The motor drives the rotating shaft to rotate, and the test cylinder 1 6 and the test cylinder 2 7 connected to the rotating shaft can be rotated. The rotating parts here can be structures that can be thought of by those skilled in the art to enable the test cylinder 1 6 and the test cylinder 2 7 to rotate. Limited to the implementation form of the motor and the rotating shaft; when in use, the test cylinder 1 6 and the test cylinder 2 7 are in an upright state, the motor 22 drives the turntable 23 to rotate, and the rotation of the turntable 23 drives the driving rod 24 and the connecting rod 2 25 to move laterally along the chute 21 in the chute 21. The chute 21 plays a guiding role here, and the test cylinder 1 6 and the test cylinder 2 7 can be operated to move laterally to add materials or liquids to them; when the oscillation effect is achieved, the rotating component is started to rotate the test cylinder 1 6 and the test cylinder 2 7 90° to a lying state respectively, and the moving component is started. Under the premise of lateral movement, the oscillation effect can be achieved.

[0021] like Figure 3 As shown, when the test tube 1 6 and the test tube 2 7 oscillate, in order to seal the solution inside, a cylinder cover is provided to achieve a sealing effect, as shown in FIG. Figure 10 As shown, the test cylinder 1 6 and the test cylinder 2 7 both include a cylinder body 44 and a cylinder cover 45 that is U-shaped as a whole. The side lengths of the cylinder cover 45 on both sides are different. The side of the cylinder cover 45 connected to the cover of the cylinder body 44 is longer and is provided with a sealing plug 26. A clamp 27 is provided on the cylinder body 44, and a vertical plate 28 connected to the clamp 27 is provided at the back of the cylinder body 44. An electric cylinder 29 is fixed to the back of the upper part of the vertical plate 28. The shorter side of the cylinder cover 45 is hingedly provided at the output end of the electric cylinder 29. The vertical plate 28 is also fixed with ear plates 30 located on both sides of the top of the electric cylinder 29, and a connecting shaft 31 is hingedly provided between the ear plate 30 and the cylinder cover 45. During use, the electric cylinder 29 is driven to push up the short side of the cylinder cover 45. Under the limit of the connecting shaft 31, the cylinder cover 45 uses the connecting shaft 31 as the rotation axis to lift the long side of the longer side of the cylinder cover 45, thereby opening the cover of the cylinder body 44. Similarly, after the electric cylinder 29 is reset, the short side of the cylinder cover 45 is retracted, and the long side of the longer side of the cylinder cover 45 is lowered to the cover of the cylinder body 44, thereby sealing the cylinder body 44.

[0022] like Figure 6As shown, in order to realize that liquid pipe 1 8 and liquid pipe 2 9 are respectively inserted into test cylinder 1 6 and test cylinder 2 7 for adding liquid, connecting parts are rotatably provided between the linear guide rail 20 and the liquid pipe 1 8 and liquid pipe 2 9. The rotating part is arranged on one of the connecting parts, including a motor 22, a rotating shaft and a connecting arm connected in sequence. The connecting arm includes an arm 1 32 fixedly connected to the liquid pipe 1 8 and liquid pipe 2 9 respectively, an arm 2 33 hingedly connected to the two arms 1 32, one end of which is hingedly connected to the arm 1 32 and the arm 2 33 near one end of the motor 22, and the other end of which is fixedly connected to the rotating shaft. An arm 34, one end of the liquid pipe 1 8 and the liquid pipe 2 9 are both connected to a water pump, and the bottom side wall of the other end is provided with a water outlet. During use, first move the test tube 1 6 and the test tube 2 7 to the lower part of the corresponding liquid tube 1 8 and the liquid tube 2 9, and then drive the linear guide 20, so that the liquid tube 1 8 and the liquid tube 2 9 can be respectively inserted into the test tube 1 6 and the test tube 2 7 to add liquid; the setting of the rotating part is to flush the inner wall of the test tube 1 6 and the test tube 2 7 after oscillation, because during the oscillation process, the material in the test tube 1 6 and the test tube 2 7 may be attached to the wall. In order to ensure the accuracy of the test results, it is necessary to flush down the material attached to the wall, and the motor 22 drives the rotating shaft to rotate, and the rotating shaft acts on the connecting arm. Under the action of the connecting arm, the liquid tube 1 8 and the liquid tube 2 9 are driven to rotate, so that the water flowing out of the water outlet of the liquid tube 1 8 and the liquid tube 2 9 is sprayed circumferentially.

[0023] like Figure 4 As shown, in order to realize the movement of counterweight assembly 10 and counterweight assembly 2 11, the driving mechanism 3 includes a linear guide rail 20, and a test plate 35 is provided on the slider of the linear guide rail 20. Both ends of the test plate 35 are provided with a cross plate 36. The weighing sensor 15 is fixed on the cross plate 36, and a top plate 37 with a through opening is fixed on the top of the weighing sensor 15. The connecting rod 2513 passes through the through opening, so that the weighing sensor 15 detects the weight of the counterweight block 12. When the counterweight block 14 is placed inside the test cylinder 1 6 and the test cylinder 2 7 for testing, the counterweight block 12 is separated from the weighing sensor 15. During use, the linear guide 20 is driven, and the linear guide 20 drives the counterweight assembly 10 and the counterweight assembly 2 11 to move. When the counterweights on the counterweight assembly 10 and the counterweight assembly 2 11 contact the substances in the test cylinder 1 6 and the test cylinder 2 7, the counterweight assembly 10 and the counterweight assembly 2 11 no longer move downward. Supported by the substances in the test cylinder 1 6 and the test cylinder 2 7, the counterweight 12 placed on the weighing sensor 15 moves away from the weighing sensor 15. The value of the weighing sensor 15 is displayed as zero, and the linear guide 20 can be closed, and the next step of operation can be carried out.

[0024] like Figure 5As shown, the image acquisition mechanism is slidably arranged in the lower middle part of the box body 1, including a camera 1 38 and a camera 2 39 respectively arranged opposite to the test tube 1 6 and the test tube 2 7, and a fixing plate 40 for fixing the camera 1 38 and the camera 2 39. A sliding member 41 is provided between the fixing plate 40 and the box body 1, and the sliding member 41 realizes the movement of the fixing plate 40. People skilled in the art can adopt well-known methods to achieve it, such as linear sliding guides or mutually cooperating slides and sliders. There are many and common forms of implementation, which will not be repeated here.

Start the moving component to move the test tube 1 6 and the test tube 2 7 to the lower part of the liquid tube 1 8 and the liquid tube 2 9. After the liquid tube 1 8 and the liquid tube 2 9 are inserted into the upper end of the test tube 1 6 and the test tube 2 7, start the rotating component to rotate the liquid tube 1 8 and the liquid tube 2 9 back and forth to wash away the particles adhering to the inner wall of the test tube 1 6 and the test tube 2 7. Let it stand for 20 minutes ± 15 seconds. 8. Start the moving parts to move the test tube 1 6 and the test tube 2 7 to the lower part of the counterweight assembly 10 and the counterweight assembly 2 11, start the driving mechanism 3, and extend the counterweight assembly 10 and the counterweight assembly 2 11 into the test tube 1 6 and the test tube 2 7 until the counterweight lump 14 contacts the sediment in the test tube 1 6 and the test tube 2 7. When the weighing sensor 15 displays a number of zero, start the image acquisition mechanism and make the camera 1 38 and the camera 2 39 correspond to the test tube 1 6 and the test tube 2 7 respectively to take images and measure the height from the bottom of the test tube 1 6 and the test tube 2 7 to the bottom of the counterweight lump 14.
