[0001] This utility model belongs to the field of shear testing instruments, specifically an adjustable soil and rock shear testing instrument. Background Technology

[0002] A soil shear tester is an important device for evaluating the mechanical properties and shear characteristics of soil and rock materials. In geotechnical engineering, understanding the shear characteristics of soil and rock materials is crucial for engineering design and construction. By simulating the behavior of soil and rock materials under shear forces, the soil shear tester helps engineers better understand the mechanical properties and deformation characteristics of these materials.

[0003] In the field of geotechnical engineering, geotechnical shear testing is an important means of evaluating the mechanical properties and shear characteristics of geotechnical materials. Traditional geotechnical shear testing instruments are often inconvenient to adjust, often unable to accurately control the shear angle, and difficult to quickly adjust the shear angle, which greatly affects the test results and causes great inconvenience.

[0004] To address these issues, those skilled in the art have proposed an adjustable soil shear testing apparatus. Utility Model Content

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0029] Example 1: As shown in the attached document Figure 1 To be continued Figure 4 As shown: This utility model provides an adjustable rock and soil shear tester, including a structural component 100, including a structural component 101, a shearing component 102 disposed on one side of the structural component 101, an adjusting component 103 disposed on one side of the structural component 101, and a clamping component 104 disposed on the upper side of the adjusting component 103.

[0030] The structural component 101 includes a base 101a, a test bench 101b fixedly installed on the upper side of the base 101a, and a drive block 101c disposed on one side of the test bench 101b.

[0031] The shearing component 102 includes a linkage rod 102a rotatably disposed inside the drive block 101c and a shearing box 102b fixedly installed on one side of the linkage rod 102a. A cylinder is disposed inside the shearing box 102b, and a shearing block 102c is fixedly installed at the output end of the cylinder. The shearing box 102b, the cylinder and the shearing block 102c facilitate shearing tests on the soil and rock to be tested.

[0032] The shearing component 102 also includes a pointer 102d fixedly mounted on the outside of the linkage rod 102a and an angle disk 102e set on one side of the drive block 101c. The linkage rod 102a can drive the shearing box 102b to rotate, and the pointer 102d and angle disk 102e can facilitate the real-time display of the current tilt angle.

[0033] like Figure 3 and 4 As shown, preferably, the shearing component 102 includes a drive motor 102f disposed on one side of the drive block 101c, a rotating rod 102g disposed at the output end of the drive motor 102f, a drive gear 102h fixedly installed on the outside of the rotating rod 102g, and a driven gear 102i fixedly fitted on the outside of the linkage rod 102a. The drive gear 102h and the driven gear 102i are meshed together. The drive motor 102f, the rotating rod 102g, the drive gear 102h, and the driven gear 102i can easily drive the linkage rod 102a to rotate when needed, thereby realizing the adjustment of the shearing angle.

[0034] Preferred, such as Figure 4 As shown, the radius of the driving gear 102h is smaller than the radius of the driven gear 102i. This setting can reduce the rotation speed of the linkage rod 102a, making it easier to adjust the angle of the shear box 102b, and also improving the stability of the linkage rod 102a when it rotates.

[0035] As can be seen from the above, when using the test, after placing the soil and rock to be tested on the test bench 101b, the cylinder inside the shear box 102b is activated. The shear box 102b, cylinder, and shear block 102c facilitate the shear test on the soil and rock to be tested. When it is necessary to quickly adjust the shear angle, the drive motor 102f is activated, which drives the rotating rod 102g to rotate. The drive gear 102h and driven gear 102i drive the linkage rod 102a to rotate, thereby adjusting the tilt angle of the shear box 102b. This allows for easy adjustment of the shear tilt angle of the shear test as needed. At the same time, the pointer 102d and angle dial 102e facilitate the real-time display of the current tilt angle.

[0036] Example 2: Figure 2 As shown, based on Embodiment 1, the adjusting member 103 is slidably disposed on the adjusting plate 103a on the upper side of the test bench 101b, the rotating motor 103b is fixedly installed on one side of the test bench 101b, and the threaded rod 103c is fixedly installed on the output end of the rotating motor 103b. The adjusting plate 103a and the outer surface of the threaded rod 103c are threadedly connected. When it is necessary to adjust the shear position, the rotating motor 103b is started to drive the threaded rod 103c to rotate. The rotation of the threaded rod 103c drives the adjusting plate 103a to move back and forth on the upper side of the test bench 101b for adjustment, which facilitates the rapid adjustment of the position of soil and rock shear as needed.

[0037] The adjusting component 103 also includes a limiting rod 103d disposed on one side of the test bench 101b. The limiting rod 103d passes through the adjusting plate 103a and is slidably disposed therewith. The adjusting component 103 also includes a limiting plate 103e fixedly installed on one side of the limiting rod 103d. The limiting rod 103d can improve the stability of the adjusting plate 103a when it moves, and the limiting plate 103e can facilitate the limiting treatment of the adjusting plate 103a.

[0038] like Figure 5 and 6 As shown, specifically, the clamping member 104 includes a fixing block 104a fixedly mounted on the upper side of the adjusting plate 103a, an inclined surface 104b disposed on one side of the fixing block 104a, a screw 104c threaded on one side of the fixing block 104a, a mounting bracket 104d rotatably disposed on one side of the screw 104c, and a clamping block 104e fixedly disposed on the upper side of the mounting member. The clamping member 104 includes an arcuate portion 104f disposed on one side of the clamping block 104e, the arcuate portion 104f contacting the inclined surface 104b, and the clamping block 104e... One side is provided with a pressing part 104g and a clamping part 104h. The pressing part 104g and clamping part 104h can facilitate the pressing and clamping of the rock and soil, thereby improving the fixing effect of the rock and soil. After the rock and soil are placed on the upper side of the adjusting plate 103a, the screw 104c is rotated to drive the clamping block 104e to move obliquely downward at the inclined surface 104b of the fixing block 104a, thereby clamping and fixing the rock and soil.

[0039] As can be seen from the above, before the test, the soil and rock to be sheared are placed on the upper side of the adjusting plate 103a. The screw 104c is rotated to drive the clamping block 104e to slide obliquely downward at the inclined plane 104b to compress and clamp the soil and rock. Then, the shearing box 102b is started to perform the shearing test on the soil and rock. At the same time, during shearing, the drive motor 102f is started to drive the threaded rod 103c to rotate, which can drive the adjusting plate 103a to move back and forth on the upper side of the test platform 101b for adjustment, so as to quickly adjust the position of soil and rock shearing as needed.
