Description

Technical Field

[0001] This utility model relates to the field of cement sampling technology, specifically a bagged cement sampler. Background Technology

[0002] Bagged cement, as an indispensable basic material in construction projects, directly affects the strength, durability, and overall structural safety of concrete. The quality of cement not only influences the smooth progress of construction but also plays a decisive role in the long-term use of buildings. Therefore, to ensure that cement quality meets relevant national standards and guarantees project quality, strict sampling and testing must be carried out before cement leaves the factory and during the acceptance phase at the construction site. Cement must be sampled and tested before leaving the factory to ensure that its physical properties and chemical composition meet the specifications. At the construction site, the re-sampling and testing of incoming cement is also a key link in quality control, used to verify whether the cement's performance has changed due to external environmental influences during transportation and storage.

[0003] However, traditional sampling equipment often uses a fixed sampling tube structure. After each sampling, a certain amount of cement remains inside the sampling tube, which is difficult to completely remove. When sampling again, the old and new cement mix in the tube, causing cross-contamination. This not only affects the purity of the sample but may also lead to significant deviations in the test results, thus misleading the judgment of cement quality and affecting the concrete mix ratio and construction quality. To address this, we propose a bagged cement sampler. Utility Model Content

The propulsion assembly 6 includes a connecting shell 61 that is fixedly connected to the outer tube 1. A connecting plate 62 is fixedly connected to the side of the inner cavity of the connecting shell 61 away from the outer tube 1. A plurality of connecting grooves 65 are opened in a circular array on the connecting plate 62, and the inner cavities of each connecting groove 65 are fixed.

[0039] Limiting component 4 includes support block 1 41 and support block 2 43. The lower ends of support block 1 41 and support block 2 43 are fixedly connected to connecting shell 61.

The magnet 444 is slidably connected to the guide rod 1 443. A limit switch is fixedly connected to the side of magnet 444 away from electromagnet 442. Position rod 446, guide rod 443 and limit rod 446 are slidably connected, spring 445 is wound around the outer surface of limit rod 446, the two sides of spring 445 are fixedly connected to the side of magnet block 444 away from electromagnet 442 and the inner wall of outer shell 441 respectively, the base assembly 5 includes a card plate 52 slidably connected to the inner cavity of connecting shell 61, a connecting block 51 is fixedly connected to the side of card plate 52 away from propulsion assembly 6, a connecting block 53 is symmetrically fixedly connected to the side of connecting block 51 close to propulsion assembly 6, a connecting rod 55 is fixedly connected to the side of connecting block 51 away from card plate 52, and a handle 54 is fixedly connected to the side of connecting rod 55 away from connecting block 51.

[0040] When it is necessary to sample bagged cement, the worker holds the handle 54 and applies force to the device to puncture the cement bag. The cement in the bag will then enter the inner cavity of the connecting pipe 21 through the inner cavity of the inlet 22, and then enter the inner cavity of the inner tube 31 to store the cement sample. After that, the device is removed from the cement bag. After removal, the sample storage component 3 needs to be removed from the inner cavity of the outer tube 1 and then sent for testing.

[0041] When the inner tube 31 needs to be removed, the worker presses button 42 to energize electromagnet 442. When electromagnet 442 is energized, it generates magnetic force, which can magnetically attract magnet block 444. Then, magnet block 444 moves towards electromagnet 442, which in turn moves limit rod 446 towards one side of electromagnet 442. Then, limit rod 446 separates from the inner cavity of adjacent connecting block 2 53, releasing the position restriction of connecting block 2 53. Then, the worker applies force to handle 54, which moves handle 54 away from outer tube 1, thereby causing clamping plate 52 to slide away from outer tube 1 in the inner cavity of connecting shell 61, and then the position restriction of connecting plate 1 32 is released.

[0042] Next, under the elastic force of spring 633, spring 633 will extend, which will push push rod 634 to slide in the inner cavity of outer shell 631. When push rod 634 slides, it will apply force to connecting plate 32, causing connecting plate 32 to slide away from outer tube 1 in the inner cavity of connecting shell 61. Then, it can drive the entire sample storage assembly 3 to slide in the inner cavity of outer tube 1. Then, the worker can take out the sample storage assembly 3 from the inner cavity of outer tube 1 and send the sample storage assembly 3 containing cement sample to the testing room for testing. By setting baffle 33 and sampling hole 34, the sampling hole 34 can be sealed by baffle 33 during the sampling process to prevent cement sample leakage in the inner cavity of inner tube 31. After being sent to the testing room, baffle 33 can be separated from sampling hole 34, which makes it convenient for workers to sample cement samples from different locations and then facilitate the testing of cement samples.

[0043] Example 2

[0044] A connecting tube 21 is fixedly connected to the side of the insertion tube 2 near the sample storage component 3. The connecting tube 21 is threadedly connected to the inner cavity of the outer tube 1. An inlet 22 is opened on the side of the insertion tube 2 away from the connecting tube 21.

[0045] When sampling is required again, to avoid the cement remaining in the inner cavity of the insertion tube 2 and connecting tube 21 affecting the test results of the new cement sample, the connecting tube 21 can be separated from the outer tube 1 by rotating the insertion tube 2. Then, the insertion tube 2 can be removed, replaced with a new insertion tube 2, and the insertion tube 2 with the cement sample residue can be cleaned and waited for reuse. Then, the new sample storage component 3 is placed in the inner cavity of the outer tube 1. The position of the sample storage component 3 in the inner cavity of the outer tube 1 is limited by the cooperation of the base component 5 and the propulsion component 6. Then, the position of the base component 5 is fixed by the limiting component 4. Then, the worker can repeat the above steps to sample the new cement sample, thereby improving the accuracy of the testing process.
