Description

Technical Field

[0001] This utility model relates to the field of soil sampling, and more specifically, to an environmental monitoring soil sampling device. Background Technology

[0002] Soil sampling equipment is used to extract undisturbed soil samples from lower layers of the test soil to understand its properties. To gain a better understanding of the base layer properties, and in engineering geological exploration and investigation work, to obtain the physical and mechanical properties of the foundation soil, it is sometimes necessary to take undisturbed soil samples from deeper areas. Soil sampling refers to the methods of collecting soil samples, including the layout and sampling techniques. Profile soil sampling should be carried out after the profile observation and recording are completed. Before sampling, the profile should be prepared and cleaned, removing the topsoil, and then samples should be taken layer by layer from top to bottom, starting from the central typical location.

[0003] However, in existing technologies, the sampling tube cannot be leveled during soil sampling, causing it to tilt. This results in the soil being sampled at an angle, which hinders the staff from performing layered analysis of the soil sample based on its depth. Consequently, the staff cannot accurately perform layered analysis of the soil. To address this issue, it is necessary for those skilled in the art to develop an environmental monitoring soil sampling device. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide an environmental monitoring soil sampling device. By incorporating a rotating component and a counterweight sleeve, it facilitates the leveling of the sampling cylinder by staff, ensuring the cylinder is perpendicular to the ground. This prevents the sampling cylinder from tilting during sampling due to unevenness, which would otherwise affect the staff's ability to perform stratified analysis of the soil sample based on its depth. This addresses the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmental monitoring soil sampling device, comprising a base plate, a support rod fixedly connected to the top of the base plate, a connector fixedly connected to one end of the support rod, a rotating component disposed inside the connector, a clamping block disposed on the outer wall of the rotating component, the clamping block being slidably connected inside the connector, a threaded rod being threadedly connected inside the clamping block, a knob fixedly connected to one end of the threaded rod, the knob being rotatably connected to the outer wall of the connector, a connecting sleeve fixedly connected to the outer wall of the rotating component, a counterweight sleeve fixedly connected to the bottom of the connecting sleeve, and a spiral groove turntable rotatably connected to the bottom of the counterweight sleeve.

[0006] In a preferred embodiment, a wheel is fixedly connected to the outer wall of the spiral groove turntable, and a slider is slidably connected to the top of the spiral groove turntable.

[0007] In a preferred embodiment, the slider is slidably connected inside the counterweight sleeve, and the slider is provided with ball bearings.

[0008] In a preferred embodiment, a sampling cylinder is inserted inside the rotating component, the connecting sleeve, and the counterweight sleeve.

[0009] In a preferred embodiment, a drill chuck is fixedly installed on the outer wall of the sampling tube, and a motor output shaft is fixedly connected to the top of the drill chuck.

[0010] In a preferred embodiment, a protective sleeve is fixedly installed on the outer wall of the motor, and the protective sleeve is disposed on the top of the motor.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model, by setting a rotating part and a counterweight sleeve, facilitates the leveling of the sampling tube by the staff, making the sampling tube perpendicular to the ground, and preventing the sampling tube from tilting when it cannot be leveled, which would cause the soil sampled by the staff to tilt, affecting the staff's operation of layering and testing the soil sample according to the soil depth, and affecting the staff's layering and testing of the soil sample.

[0013] 2. This utility model, by setting up a slider and ball bearings, can limit the sampling tubes of different sizes, making it convenient for staff to change the sampling tubes of different sizes to sample the soil as needed. Furthermore, the ball bearings are set up so that the sampling tube can drive the ball bearings to rotate when it rotates and descends, without obstructing the rotation and descent of the sampling tube.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Refer to the appendix of the instruction manual. Figure 1-3 This utility model discloses an environmental monitoring soil sampling device, including a base plate 1, as detailed below. Figure 1 A support rod 2 is fixedly connected to the top of the base plate 1. A connector 3 is fixedly connected to one end of the support rod 2. A rotating part 4 is provided inside the connector 3. See details. Figure 3 The outer wall of the rotating part 4 is provided with a clamping block 5, which is slidably connected to the inside of the connecting part 3. The inside of the clamping block 5 is connected to a threaded rod 6 by a thread. One end of the threaded rod 6 is fixedly connected to a knob 7, which is rotatably connected to the outer wall of the connecting part 3. The outer wall of the rotating part 4 is fixedly connected to a connecting sleeve 8, and the bottom of the connecting sleeve 8 is fixedly connected to a counterweight sleeve 9. The bottom of the counterweight sleeve 9 is rotatably connected to a spiral groove turntable 10.

[0020] A rotating wheel 11 is fixedly connected to the outer wall of the spiral groove turntable 10. A slider 12 is slidably connected to the top of the spiral groove turntable 10. The slider 12 is slidably connected inside the counterweight sleeve 9. Ball bearings 13 are provided inside the slider 12. Sampling cylinders 14 are inserted into the rotating component 4, the connecting sleeve 8, and the counterweight sleeve 9. See details. Figure 2 A drill chuck 15 is fixedly installed on the outer wall of the sampling cylinder 14. The output shaft of the motor 16 is fixedly connected to the top of the drill chuck 15. A protective sleeve 17 is fixedly installed on the outer wall of the motor 16 and is located on the top of the motor 16.

[0021] It should be noted that, when staff need to sample the soil, firstly, the base plate 1 is fixed to the sampling position using ground nails. Then, the knob 7 is turned, causing the threaded rod 6 to rotate. This causes the threaded rod 6 to slide the clamping block 5 along the inside of the connecting piece 3, stopping the fixation of the rotating part 4. The connecting sleeve 8 and the counterweight sleeve 9 can then rotate the rotating part 4 by their own weight until they are perpendicular to the ground. At this point, the staff can turn the knob 7 in the opposite direction, causing the knob 7 to slide the clamping block 5 back to its original position along the inside of the connecting piece 3 via the threaded rod 6, thus fixing and limiting the rotation of the rotating part 4. Then, the staff can insert the sampling tube 14 into the rotating part 4, connecting sleeve 8, and counterweight sleeve 9, and rotate the rotating wheel 11, causing the rotating wheel 11 to rotate the spiral groove turntable 10. Rotating the slider 12 will cause it to slide along the inside of the counterweight sleeve 9 until the slider 12 drives the ball bearing 13 to contact the sampling cylinder 14 and then stop. The slider 12 limits the sampling cylinder 14 through the ball bearing 13, making the sampling cylinder 14 perpendicular to the ground. Finally, the operator can hold the protective sleeve 17 and start the motor 16. The motor 16 drives the sampling cylinder 14 to rotate through the drill chuck 15. The operator holds the protective sleeve 17 and moves it downward. The protective sleeve 17 drives the rotating sampling cylinder 14 downward through the motor 16 and the drill chuck 15, allowing the sampling cylinder 14 to sample the soil. This achieves the effect of vertical soil sampling and prevents the sampling cylinder 14 from being unable to be level and tilting during sampling. This would cause the soil sampled by the operator to be tilted, affecting the operator's operation of stratifying and testing the soil sample according to the soil depth.

[0022] Furthermore, by using the slider 12 to drive the ball bearing 13 to limit the sampling cylinder 14, different sizes of sampling cylinders 14 can be limited, making it convenient for staff to change to different sizes of sampling cylinders 14 to sample the soil as needed. Moreover, the ball bearing 13 ensures that the sampling cylinder 14 can rotate and descend without obstructing its rotation and descent.
