Technical Field

[0001] This utility model relates to the field of soil moisture content testing technology, specifically a foundation moisture content testing device. Background Technology

[0002] Soil moisture content testing is a standardized method for determining the proportion of water in soil by mass. It is one of the basic indicators for soil testing and is applicable to different types of soil, such as coarse-grained soil, fine-grained soil, organic soil, and frozen soil. This method calculates soil moisture content based on the principle of drying and weighing, providing key data for engineering surveys and soil analysis.

[0003] Traditional soil moisture content testing typically involves directly sampling the soil, drying it, and then placing it in a dry environment for natural cooling and drying. This requires two steps of drying, which is inconvenient for soil drying. Therefore, a foundation moisture content testing device is proposed to address the above problems. Utility Model Content

The clamping spring 11 and the slide plate 9 are closely fitted together. The two slide rods 10 are set on the left and right sides of the push rod 8 respectively. With this setting, the holding device 6 can be limited by the installation groove 3 opened in the base 1. The heat of the heating plate 4 can be transferred to the holding device 6 through the heat-conducting silicone plate 5, thereby heating the soil in the holding device 6 and drying the soil, which is convenient for weighing the soil. The clamping spring 11 can push the holding device 6 to fit tightly with the heat-conducting silicone plate 5 through the slide plate 9 and the push rod 8, and at the same time limit the holding device 6, making the installation of the holding device 6 more stable.

[0015] The holding device 6 includes a holding shell 601 and a top cover 603. The top cover 603 is located on the top of the holding shell 601, and a mounting shell 606 is installed at the bottom of the top cover 603. The bottom of the mounting shell 606 has evenly distributed ventilation holes 609. Evenly distributed physical drying bodies 608 are arranged inside the mounting shell 606. The bottom of the holding shell 601 is located within the mounting groove 3 of the base 1. A heat-conducting plate 602 is fixedly connected to the bottom of the holding shell 601. The bottom of the heat-conducting plate 602 is tightly fitted with a heat-conducting silicone plate 5. Through this arrangement, water vapor generated after the soil is heated enters the physical drying body 608 through the ventilation holes 609 of the mounting shell 606. The physical drying body 608 absorbs the water vapor, improving the drying efficiency of the soil while it is drying. A push rod 8 is fixedly connected to the top of the top cover 603, and a sealing ring 604 is installed on the outer side of the bottom of the top cover 603. The inner side of the sealing ring 604... The sealing ring 604 is tightly fitted to the mounting shell 601, and the bottom of the sealing ring 604 is tightly fitted to the holding shell 601.

[0016] Workflow: When using this foundation moisture content testing device, first connect the power supply, then remove and weigh the soil from the foundation, and place an appropriate amount of soil into the holding shell 601. Push the push rod 8 upwards, and the push rod 8 pushes the sliding plate 9 to compress the clamping spring 11 outside the sliding rod 10. Then, place the holding shell 601 into the mounting slot 3 opened in the base 1, and then slowly release the push rod 8. The clamping spring 11 pushes the cover plate to cover the top of the holding shell 601 through the push rod 8. At this time, the mounting shell 606 is installed into the holding shell 601. Under the action of the elastic force of the clamping spring 11 itself, The bottom of the sealing ring 604 is tightly fitted to the container 601, and the bottom of the heat-conducting plate 602 is tightly fitted to the heat-conducting silicone plate 5. At this time, the electric heating plate 4 is activated by the external controller. The electric heating plate 4 sends heat into the container 601 through the heat-conducting silicone plate 5 and the heat-conducting plate 602, thereby heating the soil inside the container 601. At this time, the moisture in the soil evaporates due to the heating. The evaporated water vapor is absorbed by the physical drying body 608, thereby drying the soil. After drying, the soil is naturally cooled, and then the soil is weighed. Finally, the moisture content of the soil is calculated.
