Description

Technical Field

[0001] The utility model relates to the technical field of soil moisture detection equipment, in particular to a soil moisture measuring device for rock and soil. Background Technique

[0002] The measurement of soil moisture is a key link in agriculture and environmental science, which involves the accurate assessment of the liquid water content in the soil. Generally, the measurement methods are divided into two types: one is the sampling method, that is, after collecting soil samples from the field, the water content is measured; the other is the in-situ measurement method, which uses specific instruments to directly measure the soil moisture content in the field. A soil moisture meter is a device specifically used for in-situ measurement of soil moisture, which consists of a measurement main body and a connected probe.

[0003] However, the current soil moisture measurement equipment for rock and soil geology faces many challenges in practical applications. The soil surface of rock and soil geology is relatively hard, making it difficult to insert the probe, and forcibly inserting the probe into hard soil is likely to cause damage to the probe. In addition, many devices lack protection measures for the probe after use, increasing the risk of probe damage during transportation, which cannot meet the actual use requirements. To solve these problems, we propose a new type of soil moisture measurement device, designed specifically for rock and soil geology, to improve the convenience of measurement and the durability of the device. Content of the Utility Model

[0004] In view of the problem in the above or existing technology that makes it difficult to insert the probe, and forcibly inserting the probe into hard soil is likely to cause damage to the probe, the present utility model is proposed.

[0030] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0031] Secondly, the "one embodiment" or "embodiment" referred to herein means a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate or selectively mutually exclusive with other embodiments.

[0032] Embodiment 1

[0033] Refer to Figure 1 、 4 Figs. ~6, which is the first embodiment of the present utility model. This embodiment provides a geotechnical soil moisture measurement mechanism.

[0034] Specifically, the geotechnical soil moisture measurement mechanism 100 includes a drilling assembly 101 and a measurement assembly 102 fixedly connected to the drilling assembly 101.

[0035] The drilling assembly 101 includes a sleeve 101a, a slide rod 101b movably connected inside the sleeve 101a, a handle 101c fixedly connected to the top of the slide rod 101b, a spiral blade 101d fixedly connected to the outer surface of the sleeve 101a, and an opening and closing member 101e inside the sleeve 101a.

[0036] Further, a first annular groove 101a-1 is formed inside the sleeve 101a, a chute 101a-2 vertically opened along the center line of the first annular groove 101a-1 is provided, and a soil retaining sliding sleeve 101a-3 is installed in an interference fit with the sleeve 101a.

[0037] Still further, another set of the first annular groove 101a-1 and the chute 101a-2 are symmetrically formed inside the sleeve 101a.

[0038] Among them, the slide rod 101b includes a limit sliding sleeve 101b-1 fixedly connected to the bottom of the slide rod 101b, a limit boss 101b-2 fixedly connected to the outer surface of the limit sliding sleeve 101b-1, and a second annular groove 101b-3 formed inside the limit sliding sleeve 101b-1.

[0039] Among them, the limit boss 101b-2 is provided with a chamfer to facilitate embedding into the chute 101a-2.

[0040] Preferably, the limit boss 101b-2 is slidably connected to the first annular groove 101a-1, and the limit boss 101b-2 is movably matched with the chute 101a-2.

[0041] Furthermore, two sets of the limit boss 101b-2 and the second annular groove 101b-3 are symmetrically arranged.

[0042] Preferably, the spiral blade 101d includes a conveying blade 101d-1 fixedly connected to the outer surface of the sleeve 101a, and a drilling blade 101d-2 fixedly connected to one end of the conveying blade 101d-1.

[0043] During use, place the drilling blade 101d-2 of the spiral blade 101d at the position where the geotechnical material needs to be taken, hold the handle 101c and rotate it downward. At this time, the slide bar 101b rotates, and at the same time drives the limit boss 101b-2 to rotate along the first annular groove 101a-1 to the vertex. At this time, continuing to rotate the handle 101c will drive the sleeve 101a to rotate, and the rotation of the sleeve will drive the spiral blade 101d to rotate. At this time, the drilling assembly 101 rotates downward into the geotechnical material. The geotechnical material will be loosened by the drilling blade 101d-2, and then conveyed to the ground by the conveying blade 101d-1, completing the destruction of the surface soil of the geotechnical material.

[0044] In summary, by rotating the handle 101c, the drilling assembly 101 can be drilled into the geotechnical material to reach the specified depth.

[0045] Embodiment 2

[0046] Refer to Figure 1 、 2 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an opening and closing component.

[0047] Specifically, the opening and closing component 101e includes a fixed baffle 101e-1 fixedly connected to the bottom of the retaining slide sleeve 101a-3, a movable baffle 101e-2 arranged inside the fixed baffle 101e-1, and a moving block 101e-3 arranged at the top of the movable baffle 101e-2;

[0048] Among them, the movable baffle 101e-2 is slidably connected to the retaining slide sleeve 101a-3, and the movable baffle 101e-2 is also slidably connected to the second annular groove 101b-3.

[0049] Furthermore, there are two identical groups of the fixed baffle 101e-1 and the movable baffle 101e-2 symmetrically arranged.

[0050] During use, rotate the handle 101c to drill the drilling assembly 101 into the geotechnical material at the specified depth. At this time, the hard geotechnical material on the surface will be damaged by the drilling blade 101d-2, and under the action of the conveying blade 101d-1, the hard geotechnical material will be conveyed to the surface of the geotechnical material. At this time, move the moving block 101e-3 to open the movable baffle 101e-2. At this time, the hard geotechnical material will not enter the inside of the opening and closing component 101e, and continue to rotate the handle 101c to bring the geotechnical material at the specified depth into the opening and closing component 101e.

[0051] In summary, by manually opening the opening and closing component 101e, it is possible to collect the rock and soil at a specified depth, without collecting the hard rock and soil on the surface, and without damaging the probe 102b during measurement due to the excessive hardness of the rock and soil.

[0052] Embodiment 3

[0053] Refer to Figures 1 to 3 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a measurement component.

[0054] Specifically, the measurement component 102 includes a moisture detector 102a fixedly installed on the surface of the handle 101c, and a probe 102b fixedly connected to the bottom of the moisture detector 102a;

[0055] Among them, the probe 102b is movably connected to the retaining soil sliding sleeve 101a-3.

[0056] During use, rotate the handle 101c to drill the drilling component 101 into the rock and soil at a specified depth, open the movable baffle, so that the rock and soil at the specified depth enter the opening and closing component 101e. At this time, reset the rotating handle 101c so that the limit boss 101b-2 is located at the position of the sliding groove 101a-2. At this time, press down the handle 101c, and the probe 102b can contact the soft rock and soil to be detected for accurate measurement.

[0057] In summary, by opening the opening and closing component 101e to allow the rock and soil at a specified depth to enter it, and then pressing down the probe 102b, the measurement can be completed, which is simple and convenient.
