[0033] According to an embodiment of the present invention, a sand sampling tool for rock and soil exploration is provided.

[0034] Example 1;

[0035] like Figures 1-5As shown, the rock and soil exploration sand sampler according to the embodiment of this utility model includes a support frame 1. A fixed guide rail 2 is provided at the bottom of the support frame 1. The fixed guide rail 2 has a U-shaped structure when viewed from above. There are two fixed guide rails 2 symmetrically distributed on the inner wall of the support frame 1, which facilitates the guiding work of the fixed guide rail 2.

[0036] A return spring 3 is fixedly connected to the inner wall of the fixed guide rail 2. A movable block 4 is provided at one end of the return spring 3. The movable block 4 forms a telescopic structure with the fixed guide rail 2 through the return spring 3. Several movable blocks 4 are evenly distributed inside the fixed guide rail 2, which facilitates the sliding of the movable blocks 4 by the return spring 3.

[0037] The inner wall of the movable block 4 is provided with a support shaft 5, and the outer wall of the support shaft 5 is movably connected with a rolling wheel 6. The top view of the movable block 4 is a U-shaped structure, and the rolling wheel 6 is rotatably connected to the movable block 4 through the support shaft 5, which facilitates the wear of the sliding motion of the rolling wheel 6.

[0038] Among them, the rolling wheels 6 are evenly distributed inside the moving block 4, which further ensures reduced wear.

[0039] A fixed block 7 is fixedly connected to the outer wall of the movable block 4. A buffer rope 8 is provided on the inner wall of the fixed block 7. A positioning block 9 is fixedly connected to one end of the buffer rope 8, and a pin 10 is fixedly connected to the other end of the buffer rope 8. A through hole is opened on the inner wall of the fixed block 7, and the buffer rope 8 is connected to the fixed block 7 through the through hole. The size of the positioning block 9 is larger than the size of the through hole, which facilitates the effective connection between the buffer rope 8 and the fixed block 7.

[0040] The buffer ropes 8 are symmetrically distributed at the top and bottom of the movable block 4, and the buffer ropes 8 are set at an angle when viewed from the front, which facilitates the absorption of the elasticity of the return spring 3 by the tension of the buffer ropes 8.

[0041] Specifically, the buffer rope 8 is fixed to the inner wall of the fixed guide rail 2 by the pin 10, which facilitates the fixing of the buffer rope 8.

[0042] A drive motor 11 is connected to the top of the support frame 1. A movable screw 12 is connected to the bottom of the output shaft of the drive motor 11. A movable sleeve 13 is connected to the outer wall of the movable screw 12 by a thread. A drill bit 14 is connected to the bottom of the movable sleeve 13. A limiting block 15 is connected to the surface of the movable sleeve 13 and is slidably connected to the fixed guide rail 2. By setting the fixed guide rail 2 and the internal rolling wheel 6, the friction of lifting and lowering during drilling is effectively reduced, thereby achieving the function of reducing wear, effectively extending the service life, solving the problem of excessive wear leading to limited service life, and meeting people's work needs.

[0043] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0044] In practical applications, the elasticity of the return spring 3 first causes the movable block 4 to move elastically, which in turn causes the movable block 4 to connect the rolling wheel 6 with the limiting block 15. When the limiting block 15 moves up and down, it causes the rolling wheel 6 to rotate, thus converting sliding friction into rolling friction and effectively reducing wear and tear. At the same time, when the return spring 3 causes the movable block 4 to slide, it causes the buffer rope 8 to stretch and deform. The buffer rope 8 absorbs the elasticity of the return spring 3 through its elasticity, thus achieving the buffering function and allowing the return spring 3 to quickly return to its original shape after deformation.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
