Description

Technical Field

[0001] The utility model relates to the technical field of soil thickness measurement of water conservancy projects, in particular to a soil thickness measurement mechanism. Background Art

[0002] During the construction of water conservancy projects, the thickness of the soil layer will be measured in some specific areas. At the same time, during the construction of the embankment, soil needs to be backfilled into the embankment and then compacted. After the embankment soil is backfilled, the thickness of the backfill soil also needs to be measured. When performing such measurements, a layer thickness measuring mechanism will be used to measure the thickness of the soil layer. However, the existing soil layer thickness measuring mechanisms used in water conservancy projects still have some disadvantages, such as complex structure, which makes the overall structure bulky and inconvenient to carry. Although some simple equipment is easy to carry, when measuring the thickness of the soil layer, it is still necessary to manually insert the rod into the soil layer, which is very inconvenient. For this reason, we propose a soil layer thickness measuring mechanism. Utility Model Content

The servo motor drives the external threaded rod to rotate, and when the external threaded rod rotates, it drives the lifting plate to move up and down through the connecting block by cooperating with the threaded hole. When the lifting plate moves up and down, the cooperation between the T-guide groove and the T-slider can prevent it from rotating and limit its direction, and at the same time provide a guiding effect for it, so that it can move up and down smoothly. When the lifting plate moves up and down, the motor drives the insertion rod to rotate through the motor shaft, so that the insertion rod moving downward can be quickly inserted into the soil layer. The above-mentioned soil thickness measuring mechanism is not only simple in structure, but also greatly reduces the weight of the measuring mechanism, making it easy to carry and use. At the same time, it can also be quickly and effectively inserted into the soil layer when measuring the soil layer. BRIEF DESCRIPTION OF THE DRAWINGS
