Its main purpose is to determine the appropriate bearing stratum, determine the foundation type based on the bearing capacity of the bearing stratum, and calculate foundation parameters. Geological exploration methods include: 1. Pit and trench exploration: Through manual or mechanical excavation, the state of rock and soil strata is directly observed and undisturbed soil samples are obtained; 2. Drilling: Using a drill rig to drill holes into the stratum, identify the strata, and obtain samples is a common exploration method in engineering geological surveys; 3. Geophysical exploration: This involves studying changes in the geophysical field and detecting stratum lithology and geological structure. It includes gravity exploration, magnetic exploration, electrical exploration, and seismic exploration. Geological exploration plays an important role in mineral exploration, engineering construction, resource development, and other fields, providing essential geological data for related design and construction.

Moreover, when sampling, the worker may not be able to maintain vertical drilling due to the need to hold the sampler for a long time, which will affect the collection of soil and even the analysis of soil data. Therefore, an electric rotary sampler for geological exploration is needed. Utility Model Content

[0025] The following will be combined with the accompanying 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.

[0026] This embodiment provides an electric rotary sampler for geological exploration, an electric rotary sampler for geological exploration, such as Figure 1 、 2 As shown, in order to facilitate soil sampling, a trolley 1 is included, on which an installation box 2 is fixed, a protective box 3 is provided in the installation box 2 for lifting, and a rotating mechanism 90 is provided in the protective box 3, which can drive the soil sampling drill 4 to rotate.

[0027] When sampling, the trolley 1 is first moved to the target location, and then the protective box 3 is lowered to drive the rotating mechanism 90 to descend, thereby driving the soil sampling drill 4 to descend, and the soil sampling drill 4 is rotated to complete the work of drilling into the soil, thereby improving the effect of soil collection and facilitating soil data analysis.

[0028] like Figure 1-3 As shown, in order to improve the stability during soil sampling, an ear plate 9 is fixed on the protection box 3, and a sheath 10 is fixed on the ear plate 9. A rod 11 that can be inserted into the soil is slidably provided in the sheath 10, and a compression spring 12 is provided between the rod 11 and the sheath 10. The compression spring 12 can keep the rod 11 extended out of the sheath 10 in a free state.

[0029] When the protection box 3 descends, it can drive the ear plate 9 to descend, and then drive the sheath 10 to descend, and then drive the compression spring 12 to descend, and then drive the insertion rod 11 to descend. When the insertion rod 11 is inserted into the soil, as the protection box 3 descends, the compression spring 12 begins to be compressed, so that the insertion rod 11 and the protection box 3 can have different depth strokes. Through the cooperation of the ear plate 9, the sheath 10 and the compression spring 12, the descent of the protection box 3 can drive the insertion rod 11 to be inserted into the soil, and at the same time, the insertion rod 11 and the protection box 3 can have different depth strokes, which is convenient for the fixing work of the trolley 1 and for improving the stability of the trolley 1.

[0030] like Figure 2 As shown, in order to facilitate the discharge of soil in the soil sampling drill 4, a push rod 5 is slidingly provided in the soil sampling drill 4, and a two-way sliding rod 6 is rotatably provided in the mounting box 2. One end of the two-way sliding rod 6 is slidably provided with one end of a first sleeve 7, and the other end of the first sleeve 7 is rotatably provided on the protective box 3. The other end of the two-way sliding rod 6 is slidably provided with one end of a second sleeve 8, and the other end of the second sleeve 8 is rotatably provided on the push rod 5.

[0031] After sampling is completed, the protection box 3 rises, which in turn drives the first sleeve 7 to move, which in turn drives the two-way sliding rod 6 to rotate, which in turn drives the second sleeve 8 to move, which in turn drives the push rod 5 to descend. Through the rising of the soil sampling drill 4 and the descending of the push rod 5, the soil in the soil sampling drill 4 is discharged outside the soil sampling drill 4.

[0032] like Figure 1 As shown, in order to improve the stability of the trolley 1, a self-locking universal wheel 13 is installed at the bottom of the trolley 1. In this embodiment, the self-locking universal wheel 13 adopts the existing technology product, so it will not be described in detail.

[0033] like Figure 2 As shown, the specific lifting structure of the protection box 3 is as follows: the protection box 3 is driven by an electric push rod 14, and the electric push rod 14 is fixed on the installation box 2.

[0034] like Figure 2 As shown, the specific structure of the rotating mechanism 90 is as follows: the rotating mechanism 90 includes a rotating rod 91, which is rotatably arranged in the protective box 3, and a soil sampling drill 4 is detachably installed under the rotating rod 91. A driven gear 92 is coaxially fixed on the rotating rod 91, and the driven gear 92 is meshed with a main gear 93, and the main gear 93 is rotatably arranged in the installation box 2.

[0035] The rotation of the main gear 93 can drive the driven gear 92 to rotate, thereby driving the rotating rod 91 to rotate, and further driving the soil sampling drill 4 to rotate.

[0036] like Figure 2 As shown, the specific driving method of the main gear 93 is: the main gear 93 is driven by a motor 94, and the motor 94 is fixed under the protection box 3.

[0037] like Figure 2 As shown, the specific detachable structure of the soil sampling drill 4 is as follows: the rotating mechanism 90 also includes a mounting screw 95, which is provided with an external thread. The mounting screw 95 is fixed under the rotating rod 91, and the soil sampling drill 4 can be threadedly connected to the mounting screw 95.

[0038] like Figure 2 As shown, in order to facilitate driving the push rod 5, the mounting screw 95 and the rotating rod 91 are hollow structures, and the push rod 5 is slidingly provided inside the mounting screw 95 and the rotating rod 91. A sliding hole is opened on the mounting box 2, and the push rod 5 can extend from the sliding hole.

[0039] like Figure 1 As shown, in order to facilitate pushing the trolley 1, a handle 15 is fixed on the installation box 2.

[0040] In order to improve the gear strength, the steel material of the main gear 93 and the driven gear 92 is 40Cr.

[0041] In order to facilitate the control of the electric linear actuator 14 , the electric linear actuator 14 is electrically connected to a controller. In this embodiment, the controller adopts an 8-bit single-chip microcomputer.

[0042] During the working process, when sampling, the trolley 1 is first moved to the target location, and then the electric push rod 14 is extended, thereby driving the installation box 2 and the rotating mechanism 90 and the soil sampling drill 4 to descend, thereby driving the first sleeve 7 to move, thereby driving the two-way sliding rod 6 to rotate, thereby driving the second sleeve 8 to move, and thereby driving the push rod 5 to rise.

[0043] When the soil sampling drill 4 descends, the motor 94 is started, which drives the rotating shaft to rotate, which in turn drives the main gear 93 to rotate, which in turn drives the driven gear 92 to rotate, which in turn drives the rotating rod 91 to rotate, which in turn drives the mounting screw 95 to rotate, and thus drives the soil sampling drill 4 to rotate.

[0044] The descent of the installation box 2 can drive the ear plate 9 to descend, and then drive the sheath 10 to descend, and then drive the compression spring 12 to descend, and then drive the insertion rod 11 to descend, and then insert the insertion rod 11 into the soil. After the insertion rod 11 is inserted into the soil, as the sheath 10 descends, the compression spring 12 begins to compress.

[0045] After the sampling work is completed, the motor 94 is turned off, the electric push rod 14 is shortened, and the installation box 2, the rotating mechanism 90, and the soil sampling drill 4 are driven to rise, which in turn drives the first sleeve 7 to move, and then drives the two-way sliding rod 6 to rotate, and then drives the second sleeve 8 to move, and then drives the push rod 5 to descend, so that the soil in the soil sampling drill 4 can be discharged.
