Description

Technical Field

[0001] This utility model relates to the field of moisture content measurement technology, specifically a fully automatic rapid moisture content analyzer. Background Technology

[0002] In building construction, it is crucial to determine the moisture content of aggregates, backfill soil, graded crushed stone, and stabilized layers. The moisture content of aggregates directly affects their mixing effect with other materials and the strength and stability of the final hardened product. Excessive moisture content can lead to quality problems such as shrinkage and cracks in crushed stone during construction, reducing its durability and service life. Therefore, it is necessary to determine the moisture content of sand.

[0003] Traditional methods for determining moisture content primarily involve oven drying; some methods use alcohol combustion, but these methods have the following problems:

[0004] 1. Using an oven for drying results in long drying time and poor efficiency;

[0005] 2. Although the alcohol combustion method is highly efficient, the results are prone to deviation and it is not a standard method in many tests, thus having a limited scope of application.

[0006] 3. On-site testing cannot be conducted simultaneously, affecting construction progress. Utility Model Content

[0007] The purpose of this invention is to provide a fully automatic rapid moisture content tester, which uses microwave scanning equipment in conjunction with a data processing controller to quickly determine the moisture content, effectively reducing the drying time in an oven and improving efficiency; it is convenient and lightweight, and can be used to quickly determine the compaction quality results on site, greatly improving the on-site construction progress.

[0023] Please see Figure 1-6 The fully automatic rapid moisture content tester includes a machine base 1 and a microwave scanning device body 3. A housing 2 is fixed to the inner wall of the machine base 1. A first electric slider 5 and a second electric slider 23 are set on the upper part of the inner wall of the housing 2. A groove 4 is opened on the upper part of the inner wall of the housing 2 to cooperate with the first electric slider 5 and the second electric slider 23. The microwave scanning device body 3 is fixed to the bottom of the second electric slider 23. A first sleeve 6 is fixed to the bottom of the first electric slider 5. A second sleeve 7 is slidably connected to the inner wall of the first sleeve 6. A movable rod 8 is slidably connected to the inner wall of the second sleeve 7. A storage shell 9 is fixed to the bottom of the movable rod 8. A smoothing device 10 is fixed to the bottom of the storage shell 9. Multiple limiting plates 11 are fixed to the inner wall of the housing 2. A tray 12 is slidably connected to the surface of the limiting plates 11. A support leg 14 and a battery 15 are fixed to the bottom of the machine base 1. A controller 16 is fixed to the surface of the machine base 1. A protective door 13 is hinged to the surface of the machine base 1.

[0024] The design of the machine base 1 makes this device lighter and easier to carry. With the battery 15, it can operate without an external power source. The surface of the tray 12 is used to store sand samples. Both the first electric slider 5 and the second electric slider 23 can move via the slide groove 4, allowing the smoother 10 and the microwave scanning device body 3 to move left and right above the tray 12. The second sleeve 7 can slide on the inner wall of the first sleeve 6, and the movable rod 8 can also slide on the inner wall of the second sleeve 7, allowing the housing 9 to adjust the height of the smoother 10, so that the surface of the smoother 10 can contact the sand on the surface of the tray 12. The smoothing device 10 can smooth the sand when it moves, making it easier for the microwave scanning device 3 to detect the sample when it moves via the second electric slider 23, resulting in more accurate sample detection results. The design of multiple limit plates 11 also allows the tray 12 to be placed on the surface of the limit plates 11 at different heights as needed. The protective door 13 can rotate, and after the protective door 13 rotates upward into the machine 1, the interior of the machine 1 can be sealed to prevent moisture loss from the sample. The results scanned by the microwave scanning device 3 can be transmitted to the controller 16, which can then process and transmit the data.

[0025] Furthermore, mounting sleeves 19 are fixed to the bottom of the surfaces of the first sleeve 6 and the second sleeve 7. The first connecting block 20 and the second connecting block 21 are fixed to the surface of the mounting sleeve 19. The surface of the mounting sleeve 19 is provided with a groove. A knob 22 passes through the surface of the first connecting block 20. The second connecting block 21 is threaded through the surface of the knob 22.

[0026] After the second sleeve 7 or the movable rod 8 has adjusted its movable position, the knob 22 can be rotated to move towards the position of the second connecting block 21, thereby deforming the mounting sleeve 19 and gradually reducing the grooved area on the surface of the mounting sleeve 19. This allows the mounting sleeve 19 to apply a large amount of friction, so that the second sleeve 7 or the movable rod 8 can achieve a limiting effect.

[0027] Furthermore, a telescopic rod 18 is fixed to the top of the storage shell 9, and the top of the telescopic rod 18 is fixedly connected to the bottom of the first electric slider 5;

[0028] When the storage shell 9 is raised or lowered, the telescopic rod 18 will also extend or retract, so that the storage shell 9 can be guided and avoid tilting during the movement.

[0029] Furthermore, a pull rod 17 slides through the surface of the storage shell 9;

[0030] The pull rod 17 makes it easier to move the storage shell 9 and allows the pull rod 17 to be pulled out from inside the storage shell 9, thus enabling the tray 12 to be picked up.

[0031] Furthermore, a friction pad 24 is fixed to the bottom of the support leg 14;

[0032] The friction pad 24 can increase the friction at the bottom of the support leg 14 and can cushion the support leg 14, thereby improving the stability of the machine platform 1.

[0033] Furthermore, magnets 25 are embedded and fixed on both the surface of the protective door 13 and the surface of the machine base 1;

[0034] By designing multiple magnets 25, after the protective door 13 rotates into the interior of the machine base 1, the magnets 25 on the surface of the machine base 1 will attract the magnets 25 on the surface of the protective door 13, thus preventing the protective door 13 from rotating downwards on its own.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
