Description
Technical Field
[0001] The utility model relates to the technical field of samplers, in particular to a rock and soil sampler for detection. Background Art
[0002] When testing rock and soil samples, a sampler is needed to collect samples. Among them, there is a sampler that can collect soil samples. This sampler is mainly composed of a mounting rod, a sampling tube installed on the mounting rod, and a handle. When sampling, you only need to place the sampling tube vertically to the ground, and then press down the handle to insert the sampling tube into the soil to complete the sampling work.
[0003] The above-mentioned and existing related technologies often have the following defects: when taking soil samples, the user needs to hold the sampling tube perpendicular to the ground and then press down the handle. During this process, the user's arm is prone to shaking, causing the sampling tube to tilt, resulting in inaccurate sampling depth, thereby reducing the practicality of the sampler. Utility Model Content

When the bolt abuts against the inner wall of the groove, the bolt prevents the mounting rod from moving further downward, thereby limiting the sampling depth of the sampling tube.
[0009] Preferably, the vertical cross-section of the groove is a right-angled trapezoid. Since the vertical cross-section of the groove is a right-angled trapezoid, the sampling depth of the sampling tube can be controlled by adjusting the position of the bolt in the guide ring, thereby facilitating the collection of samples of the same depth at different sampling points.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-5 As shown, a rock and soil sampler for detection includes a mounting rod 1, a sampling barrel 2 is fixedly connected to the lower end of the mounting rod 1, a handle 3 is slidably connected inside the mounting rod 1, a guide structure 4 is provided on the arc surface of the mounting rod 1, and the guide structure 4 includes a guide ring 41, the guide ring 41 is slidably sleeved on the arc surface of the mounting rod 1, a connecting rod 42 is fixedly connected to the arc surface of the guide ring 41, one end of the connecting rod 42 is fixedly connected to a pedal 43, and the lower surface of the pedal 43 is fixedly connected to an insertion rod 44; when working, by setting the guide structure 4, in the process of the sampling barrel 2 moving downward, the sampling barrel 2 will be vertically inserted into the soil for sampling under the guidance of the guide ring 41, so as to prevent the sampling barrel 2 from tilting and causing inaccurate sampling depth, thereby improving the practicability of the sampler.
[0025] The arc surface of the insertion rod 44 is fixedly connected with an extension plate 45; when working, the extension plate 45 can improve the stability of the insertion rod 44 in the soil.
[0026] A plurality of anti-slip strips 46 are fixedly connected to the upper surface of the pedal 43 ; when in operation, the anti-slip strips 46 can increase the friction force on the surface of the pedal 43 .
[0027] The guide ring 41 is internally threaded with a bolt 47 , and the arc surface of the mounting rod 1 is provided with a groove 48 ; during operation, when the bolt 47 abuts against the inner wall of the groove 48 , the bolt 47 prevents the mounting rod 1 from moving further downward, thereby limiting the sampling depth of the sampling tube 2 .
[0028] The vertical section of the groove 48 is a right-angled trapezoid; during operation, since the vertical section of the groove 48 is a right-angled trapezoid, the sampling depth of the sampling tube 2 can be controlled by adjusting the position of the bolt 47 in the guide ring 41, thereby facilitating the collection of samples of the same depth at different sampling points.
[0029] A limiting structure 5 is provided on the surface of the mounting rod 1, and the limiting structure 5 includes a clamping rod 51, and the clamping rod 51 passes through the mounting rod 1. A plurality of clamping holes 52 are opened on the surface of the handle 3, and the size of the clamping rod 51 is adapted to the size of the clamping hole 52. When working, by setting the limiting structure 5, when the position of the handle 3 is adjusted according to the height of the user, the position of the handle 3 can be restricted, thereby facilitating the user to operate the handle 3 for sampling, thereby improving the convenience of using the sampler.
[0030] The arc surface of the mounting rod 1 is fixedly connected with a fixing plate 53, and the surface of the fixing plate 53 is fixedly connected with a magnetic block 54. The clamping rod 51 is an iron rod. When working, the clamping rod 51 slides and contacts with the magnetic block 54. At this time, the magnetic block 54 attracts the clamping rod 51 to prevent the clamping rod 51 from sliding out of the clamping hole 52, thereby ensuring that the clamping rod 51 can stably limit the position of the handle 3.
[0031] A pull ring 55 is rotatably connected inside the clamping rod 51 . When the clamping rod 51 is in operation, the pull ring 55 is pulled, and the pull ring 55 drives the clamping rod 51 to slide, so that the pull ring 55 facilitates pulling the clamping rod 51 .
[0032] Working principle: when it is necessary to sample the rock and soil samples to be tested, move the sampling tube 2 to a suitable position, and then insert the rod 44 into the soil with the help of the pedal 43. At this time, the anti-slip strip 46 increases the friction force on the surface of the pedal 43. The sliding of the rod 44 will drive the extension plate 45 to move synchronously. The rod 44 can increase the contact area between the pedal 43 and the ground to prevent the pedal 43 from sliding. The extension plate 45 improves the stability of the rod 44 in the soil. Then, turn the bolt 47, and the bolt 47 will move along the guide ring 41 with the help of the thread. When the bolt After 47 moves to a suitable position, the handle 3 is pressed downward, and the sampling tube 2 will be vertically inserted into the soil for sampling under the guidance of the guide ring 41. During the downward movement of the sampling tube 2, the mounting rod 1 will move synchronously. When the bolt 47 abuts against the inner wall of the groove 48, the bolt 47 will prevent the mounting rod 1 from continuing to move downward, thereby limiting the sampling depth of the sampling tube 2. Since the vertical section of the groove 48 is a right-angled trapezoid, the sampling depth of the sampling tube 2 can be controlled by adjusting the position of the bolt 47 in the guide ring 41, thereby facilitating the collection of samples of the same depth at different sampling points.
[0033] When the position of the handle 3 needs to be adjusted according to the height of the user, the pull ring 55 is pulled, and the pull ring 55 will drive the clamping rod 51 to slide. When the clamping rod 51 is out of contact with the clamping hole 52, the handle 3 can be slid along the inner wall of the mounting rod 1 to adjust the position of the handle 3. After the adjustment is completed, the clamping rod 51 is passed through the mounting rod 1 and reinserted into the clamping hole 52. The clamping rod 51 has the function of limiting the position of the handle 3. The clamping rod 51 slides and contacts with the magnetic block 54. At this time, the magnetic block 54 will attract the clamping rod 51 to prevent the clamping rod 51 from sliding out of the clamping hole 52, thereby ensuring that the clamping rod 51 can stably limit the position of the handle 3.
