Abstract
Description
Technical Field
[0001] This utility model relates to the field of building sand testing and sampling technology, and more specifically, it relates to a sampling device for building sand testing. Background Technology
[0002] Construction aggregates refer to granular materials such as sand and stone that are mixed with cement and water when making mortar or concrete. They are also called aggregates. Inferior aggregates can seriously affect the quality of concrete buildings. Therefore, relevant supervision departments will test construction aggregates. When testing construction aggregates, sampling devices are required to take samples of the aggregates.
[0003] A search revealed that Chinese utility model patent application number CN202122234877.5 discloses a high-performance concrete aggregate sampling device, which includes a rotatable fixed seat and a base. The fixed seat is installed inside the base, and a main beam is fixed on the fixed seat. A lifting telescopic beam is connected to the main beam, and at least one lifting hydraulic cylinder is provided between the fixed seat and the telescopic beam. A material collection cylinder is fixed at the front end of the telescopic beam away from the main beam. The material collection cylinder is provided with a spiral blade, which is fixed on a shaft and driven by a material collection motor.
[0004] It samples sand and gravel at different depths by adjusting the height of the sampling cylinder. However, during the process of inserting the sampling cylinder into the sand and gravel, the upper layer of sand and gravel will directly enter the sampling cylinder. This makes it difficult to accurately sample the sand and gravel within the corresponding depth range, affecting the accuracy of the test. In addition, after sampling at one location, the sand and gravel inside the sampling cylinder needs to be removed before sampling at other locations. This makes it inconvenient to sample multiple locations simultaneously, resulting in a longer sampling time and reduced sampling efficiency. Utility Model Content

[0030] Please see Figures 1-5 A sampling device for testing building sand includes a base 1 and multiple sampling cylinders 2. A fixed seat 3 is fixedly connected to the top of the base 1. Multiple lifting mechanisms are provided on the fixed seat 3 and the base 1. Each of the multiple lifting mechanisms is connected to a translation mechanism. Each of the multiple translation mechanisms is connected to an adjustment mechanism. Each of the multiple adjustment mechanisms is connected to a cross seat 4. The multiple sampling cylinders 2 are respectively fixedly installed on the multiple cross seats 4. Four first electric cylinders 5 are fixedly connected to the top of the four first electric cylinders 5. A mounting plate 6 is fixedly connected to the top of the mounting plate 6. A motor 7 is installed on the top of the mounting plate 6. A rotating shaft 8 is fixedly connected to the output end of the motor 7. A spiral blade 9 is fixedly connected to the outer wall of the inner part of the sampling cylinder 2 on the rotating shaft 8. A sealing column 10 is fixedly connected to the bottom end of the rotating shaft 8. The sealing column 10 is a conical column, which facilitates the insertion of the sampling cylinder 2 into the interior of the sand and gravel.
[0031] Specifically, four first electric cylinders 5 push the mounting plate 6, motor 7, rotating shaft 8, and sealing column 10 upwards, so that the top of the sealing column 10 contacts the bottom of the sampling cylinder 2. The height of the sampling cylinder 2 is adjusted by the lifting mechanism, and the sampling cylinder 2 is inserted to the corresponding depth of the sand and gravel. Then, the four first electric cylinders 5 pull the mounting plate 6, motor 7, rotating shaft 8, and sealing column 10 downwards, so that the sealing column 10 is separated from the sampling cylinder 2 by a certain distance. Then, the motor 7 drives the rotating shaft 8, spiral blade 9, and sealing column 10 to rotate. The rotation of the spiral blade 9 transports the sand and gravel at the corresponding depth into the interior of the sampling cylinder 2, which can prevent sand and gravel at other depths from mixing in. This facilitates accurate sampling of sand and gravel within a certain depth range and improves efficiency. The accuracy of the test is improved by setting up multiple lifting mechanisms, multiple translation mechanisms, multiple adjustment mechanisms, and multiple sampling cylinders 2. This allows multiple sampling cylinders 2 to simultaneously sample different locations of sand and gravel, avoiding the need to sample once and then sample again, saving sampling time and improving sampling efficiency. The translation mechanism facilitates the adjustment of the distance between adjacent sampling cylinders 2, and the adjustment mechanism facilitates the adjustment of the distance between the sampling cylinder 2 and the fixed base 3, thereby facilitating the adjustment of the position of the sampling cylinder 2. This allows the sampling cylinder 2 to be adjusted to the appropriate position according to the usage requirements, facilitating the sampling of sand and gravel at different locations. The sampling mechanism facilitates the adjustment of the height of the sampling cylinder 2, facilitating the sampling of sand and gravel at different depths.
[0032] Please see Figure 1 and Figure 3 The lifting mechanism includes a second electric cylinder 11, which is fixedly installed on the base 1. A top plate 12 is fixedly connected to the top of the second electric cylinder 11. Multiple lifting slots 13 are evenly arranged on the top of the fixed base 3. A lifting plate 14 is fixedly connected to the bottom of the top plate 12. The lifting plate 14 slides with the lifting slots 13 to ensure that the lifting plate 14 lifts and lowers stably.
[0033] Specifically, the second electric cylinder 11 drives the top plate 12, the translation mechanism, the adjustment mechanism and the sampling cylinder 2 to move up and down, so as to adjust the height of the sampling cylinder 2, so as to insert the sampling cylinder 2 to the corresponding depth of the sand and gravel, and to sample the sand and gravel at the corresponding depth.
[0034] Please see Figure 1 and Figure 4 The translation mechanism includes a fixed column 15, which is fixedly connected to the top plate 12. A convex groove 16 is provided on the side end of the fixed column 15. A convex seat 17 is slidably provided inside the convex groove 16. A fixing screw 18 is threadedly connected to the convex seat 17. A strip groove 19 communicating with the convex groove 16 is provided at the top end of the fixed column 15. The fixing screw 18 is located inside the strip groove 19 to facilitate fixing the convex seat 17.
[0035] Specifically, by sliding the convex seat 17 inside the convex groove 16, it is convenient to adjust the position of the convex seat 17, the adjustment mechanism and the sampling cylinder 2, to adjust the spacing between adjacent sampling cylinders 2, and to disassemble and assemble the convex seat 17, the translation mechanism and the sampling cylinder 2, so as to install different numbers of sampling cylinders 2.
[0036] Please see Figure 1 and Figure 4 The adjustment mechanism includes a horizontal plate 20 and a third electric cylinder 21. The horizontal plate 20 is fixedly connected to the convex seat 17. An adjustment plate 22 is slidably arranged on the horizontal plate 20 and is fixedly connected to the horizontal seat 4. The third electric cylinder 21 is installed on the horizontal plate 20. A fixing block 23 is fixedly connected to the telescopic rod of the third electric cylinder 21 and is fixedly connected to the horizontal seat 4. A limit groove 24 is provided on the horizontal plate 20 and a limit block 25 is provided on the adjustment plate 22. The limit block 25 slides with the limit groove 24 to limit the adjustment plate 22.
[0037] Specifically, the third electric cylinder 21 pushes the fixed block 23, the cross seat 4 and the sampling cylinder 2 to move, so as to facilitate the adjustment of the distance between the sampling cylinder 2 and the fixed seat 3.
[0038] In summary, when using the overall equipment:
[0039] By sliding the convex seat 17 inside the convex groove 16, a corresponding number of sampling cylinders 2 are installed on the fixed column 15 and adjusted to a suitable position. Then, the fixing screws 18 are tightened to fix the convex seat 17. Then, the second electric cylinder 11 is used to adjust the sampling cylinder 2 to the highest position. Then, the third electric cylinder 21 drives the fixed block 23, the cross seat 4, and the sampling cylinder 2 to move, adjusting multiple sampling cylinders 2 to their respective positions. Then, the four first electric cylinders 5 push the mounting plate 6, the motor 7, the rotating shaft 8, and the sealing column 10 upward, so that the top of the sealing column 10 contacts the bottom of the sampling cylinder 2. Then, the second electric cylinder 11 pulls the top plate 12 downward, so that the corresponding sampling cylinder 2 is inserted into the sand and gravel to a suitable depth. Then, the four first electric cylinders 5 pull the mounting plate 6, motor 7, rotating shaft 8 and sealing column 10 downwards, so that the sealing column 10 is separated from the sampling cylinder 2 by a certain distance. Then, the motor 7 drives the rotating shaft 8, spiral blade 9 and sealing column 10 to rotate, and the surrounding sand and gravel will slide to the position between the sealing column 10 and the sampling cylinder 2. The rotating spiral blade 9 transports the sand and gravel into the sampling cylinder 2. After the motor 7 has run for a certain period of time, the motor 7 stops working, and the four first electric cylinders 5 push the mounting plate 6, motor 7, rotating shaft 8 and sealing column 10 upwards to prevent the sand and gravel inside the sampling cylinder 2 from falling out. Then, the second electric cylinder 11 pushes the top plate 12 and the sampling cylinder 2 to the upper side of the sand and gravel, thus completing the sampling of sand and gravel from multiple locations.
