Description

Technical Field

[0001] The utility model belongs to the technical field of earthwork and soil detection, and particularly relates to a device for earthwork measurement. Background Art

[0002] Earthwork includes all aspects of earth (stone) excavation, filling, transportation, drainage, precipitation, etc. Earthwork is generally widely present in soil and stone excavation projects, and during the construction of earthwork projects, it is necessary to measure the moisture content of the soil to determine the moisture content of the soil. At this time, an earthwork measurement device is needed to complete the soil moisture detection, such as the existing patent with the publication number "CN212932618U" disclosed "an earthwork measurement device, including a limit handle and a plug rod, the top end of the limit handle is provided with a plug rod at a vertical position, the plug rod is inserted into the limit handle, the bottom end of the limit handle is provided with a handle at a vertical position, and the handle is integrally formed at the limit handle". It can be seen that what is described in the application is a common earthwork measurement device, which can complete the soil moisture measurement by inserting the probe into the soil;

[0003] When the earthwork measurement equipment in the prior art is actually used, it is necessary to insert a probe into the soil to measure moisture. However, after the probe is pulled out, mud and dirt are likely to remain on the surface, especially the moisture sensor at the front end of the probe is likely to be covered by mud. The existing earthwork measurement equipment does not have a structure designed to facilitate cleaning of the mud and dirt remaining on the probe surface. If the surface of the lever is not cleaned in time, the accuracy of the next measurement will be affected. For this reason, the utility model proposes a device for earthwork measurement.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example

[0023] See also Figures 1 to 4 , is the first embodiment of the present utility model, which provides a technical solution: a device for earthwork measurement, comprising

[0024] Host 1, handle 2 connected to host 1 via connecting line 3, probe 4 provided at the top of handle 2, and moisture sensor 41 provided at the top of probe 4. Host 1 is actually a soil moisture meter, model TZS-II, and moisture sensor 41 is model SM100.

[0025] The cleaning structure 5 is provided at the bottom end of the probe 4, including an annular sleeve 52 and an annular seat 53 which are slidably sleeved on the bottom end surface of the probe 4, and the annular sleeve 52 and the annular seat 53 are an integrated structure, and also include a cleaning sponge ring 54 which is installed on the top surface of the annular seat 53 and the inner wall of which is in contact with the surface of the probe 4. After the probe 4 is pulled out of the soil, the annular sleeve 52 and the annular seat 53 can be pushed toward the top of the probe 4 and slide back and forth, so that the cleaning sponge ring 54 can wipe and clean the mud and dirt remaining on the surface of the probe 4 and the surface of the moisture sensor 41. In the later stage, it is only necessary to regularly remove the cleaning sponge ring 54 for cleaning or replacing. The cleaning structure 5 also includes an annular base 51 fixed to the bottom end surface of the probe 4, and the top of the annular base 51 is provided with an annular slot 56 for the annular sleeve 52 to be inserted. The cleaning structure 5 also includes a limiting structure, which is arranged between the annular sleeve 52 and the annular base 51. The limiting structure includes a The two inner grooves 571 of the part, the spring 572 and the telescopic card bead 573 installed in the inner groove 571, and the annular card groove 574 opened on the bottom end surface of the annular sleeve 52, the telescopic card bead 573 is movably installed in the inner groove 571 by the spring 572, and the end of the telescopic card bead 573 pops out into the annular card groove 574, the annular sleeve 52 can be limited during daily use of the equipment to prevent the annular sleeve 52 and the annular seat 53 from sliding on their own, so that the cleaning structure 5 does not affect the normal use of the probe 4 and the equipment. When the probe 4 is pulled out of the soil, the operator only needs to push the annular sleeve 52 upward with force so that the end of the telescopic card bead 573 is squeezed into the inner groove 571, and the bottom end of the annular sleeve 52 can be smoothly pulled out from the annular slot 56, and the annular sleeve 52 and the annular seat 53 can be smoothly slid toward the top end of the probe 4, so that the cleaning sponge ring 54 can wipe and clean the mud and dirt remaining on the surface of the probe 4 and the moisture sensor 41.

[0026] One end of the spring 572 is fixed to the inner wall of the inner groove 571 , and the other end of the spring 572 is fixed to the telescopic card bead 573 .

[0027] Among them, the top surface of the annular seat 53 is provided with an annular top groove 531 corresponding to the cleaning sponge ring 54, and a disassembly structure 55 is provided between the cleaning sponge ring 54 and the annular seat 53. The disassembly structure 55 includes two plug blocks 551 provided on the bottom surface of the cleaning sponge ring 54, two sockets 552 provided on the bottom surface of the annular seat 53 and corresponding to the sockets 552, two triangular protrusions 553 provided on the surface of the annular sleeve 52, and a rectangular slot 554 provided on the side of the plug block 551 and corresponding to the triangular protrusion 553. The bottom end of the plug block 551 is inserted through the socket 552. It penetrates to the bottom of the annular seat 53, and the triangular protrusion 553 is snapped into the rectangular slot 554, which is used to limit the insertion block 551 and the cleaning sponge ring 54 to ensure the installation stability of the cleaning sponge ring 54. If the cleaning sponge ring 54 needs to be removed for cleaning or replacement later, it is only necessary to push the cleaning sponge ring 54 upward, so that the insertion block 551 moves upward and is elastically deformed by the squeezing of the triangular protrusion 553, so that the insertion block 551 can be smoothly pulled out from the socket 552, and the cleaning sponge ring 54 can be smoothly removed from the top of the annular seat 53, which is convenient for later maintenance and replacement.

[0028] Among them, the cleaning sponge ring 54 and the insert block 551 are an integrated structure. Both are made of sponge material and will undergo elastic deformation when squeezed. The top of the socket 552 is connected to the annular top groove 531 to allow the insert block 551 to pass through smoothly.

[0029] Although embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
