[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0024] The present embodiment provides a soil sampling device, which is mainly used to solve the problem that the sampling method of a manual sampler is generally to directly insert the sample into the soil for sampling. Although this method can achieve the purpose of sampling, it is often difficult to grasp the depth of sampling. The following technical solutions are provided. Figure 1-Figure 4 Give detailed instructions:

[0025] Example 1:

[0026] A soil sampling device comprises: a sampling rod 1 having a control ring 2 and a pedal 3 slidably sleeved on its surface, and a sampling tube 4 provided on one side of the pedal 3. During use, a user can install the sampling tube 4 on one side of the pedal 3 via a connecting mechanism 6, and then control the position of the control ring 2 on the surface of the sampling rod 1 via an adjustment mechanism 5 (the position of the control ring 2 on the surface of the sampling tube 4 determines the range of movement of the pedal 3 on the surface of the sampling rod 1, that is, the depth to which the sampling tube 4 is inserted into the ground). Finally, by stepping on the pedal 3, the sampling tube 4 can be driven into the ground, thereby completing the sampling. The main components of the sampling rod 1 are: a main rod 101 with two handles 102 fixedly mounted on the surface. When in use, the user can hold the two handles 102 with both hands to carry the main rod 101. At the same time, the control ring 2 and the pedal 3 are slidably sleeved on the surface of the main rod 101. The main components of the adjustment mechanism 5 are: an adjustment groove 501 provided on the surface of the main rod 101, and an adjustment threaded rod 502 is rotatably inserted into the inner wall of the adjustment groove 501. When in use, the user rotates the adjustment threaded rod 502 to drive the control ring slidably inserted into the inner wall of the adjustment groove 501 and threadedly sleeved on the surface of the adjustment threaded rod 502. 2 movement, wherein the main component of the connecting mechanism 6 is: a limiting ring 602. The connecting ring 601 is fixedly installed on the surface of the main rod 101. When in use, the user slides the sampling tube 4 into the inner wall of the connecting ring 601, and then screws the limiting ring 602 onto the surface of the sampling tube 4, so that the sampling tube 4 can be limited on the inner wall of the connecting ring 601. It should be noted that: a limiting edge is provided at one end of the sampling tube 4, which is used to cooperate with the limiting ring 602 to limit the position of the sampling tube 4 on the inner wall of the connecting ring 601. At the same time, a scale groove is provided on the surface of the main rod 101, and the user can control the depth to which the sampling tube 4 can be inserted into the ground through the scale groove.

[0027] By providing a sampling rod 1 that can be held in the hand, the user can hold the sampling rod 1, step on the pedal 3, and insert the sampling tube 4 set on one side of the pedal 3 into the ground to achieve the purpose of sampling. This sampling method is more labor-saving and also easier to control the depth of insertion into the ground.

[0028] By providing a control ring 2 that is slidably sleeved on the surface of the sampling rod 1, the user can control the position of the control ring 2 on the surface of the sampling rod 1 through the adjustment mechanism 5 during use. When the user subsequently steps on the pedal 3 to drive the pedal 3 to slide on the surface of the sampling rod 1, the pedal 3 will fit on the surface of the control ring 2, thereby being unable to continue to control the sliding of the sampling tube 4 in the soil, thereby achieving control of the sampling depth.

[0029] Example 2:

[0030] The second embodiment of this application is to further improve the present application based on the first embodiment. Figure 2In some embodiments, a pushing plate 7 is slidably inserted into the inner wall of the sampling tube 4. After the sampling is completed, the user can control the pushing plate 7 to slide on the inner wall of the sampling tube 4 through the driving mechanism 8, thereby pushing out the sample, which facilitates the removal of the sample after the sampling is completed. The main components of the driving mechanism 8 are: a spring 802, a force rod 801 is fixedly installed on the surface of the pushing plate 7, and the other end of the force rod 801 is slidably inserted into the inner wall of the sampling tube 4, and the two ends of the spring 802 are respectively fixedly installed on the force rod 801 and the surface of the pushing plate 7. During the specific operation, the user can press the force rod 801 with the sole of the foot, thereby driving the pushing plate 7 to slide on the inner wall of the sampling tube 4.

[0031] like Figure 1 、 Figure 3 As shown, in some embodiments, the surfaces of the two handles 102 are provided with grooves 9 for respectively grasping, and the surface of the pedal 3 is provided with a protrusion 10, and the surface of the protrusion 10 is slidably inserted into the inner wall of the adjustment groove 501. When the user steps on the pedal 3, the protrusion 10 can slide on the inner wall of the adjustment groove 501, ensuring the stability of the pedal 3 moving in the length direction of the main rod 101.

[0032] The workflow of this utility model:

[0033] First, the user needs to hold the two handles 102, rotate the adjustment threaded rod 502, drive the control ring 2 to slide on the inner wall of the adjustment groove 501, and then align one end of the sampling tube 4 with the ground surface, step on the foot pedal 3 and press down, and the sampling tube 4 can be driven to insert into the ground surface until the foot pedal 3 fits on the surface of the control ring 2, thereby realizing the control of the depth of the sampling tube 4 inserted into the ground surface (this structure is suitable for the current demand for multi-point sampling in an area, so that the depth difference of each sampling can be narrowed).

[0034] Secondly, after the sampling is completed, the user needs to step on the force rod 801 to drive the pushing plate 7 to slide on the inner wall of the sampling tube 4, thereby pushing the sample out of the inner wall of the sampling tube 4 to realize the discharge of the sample. This method is particularly convenient when sampling multiple times. The time and sampling effect of the user inserting the sampling tube 4 into the soil and stepping on the force rod 801 for sampling can be guaranteed.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
