[0028] See attached document Figure 1-2 An adjustable sample collection device for soil remediation, comprising:

[0029] The sampling plate 1 has an avoidance groove 2 in the middle and two symmetrical baffles 3 at the bottom; a partition 4 is provided in the middle of the two baffles 3 and a limiting plate 5 is provided on each side; multiple guide holes 6 are provided on the limiting plate 5; a cone plate 7 is welded and fixed below the two baffles 3 to facilitate the sampling plate 1 entering the soil.

[0030] The sampling assembly has multiple sets on both sides of the partition 4; the sampling assembly includes a mounting plate 8, a sampling cylinder 9 and a reset spring 10; the sampling cylinder 9 is horizontally fixed on the side of the mounting plate 8 away from the partition 4, and its open end is inserted into the guide hole 6 at the corresponding position; one end of the reset spring 10 is fixed on the partition 4 and the other end is fixed on the mounting plate 8, and is used to retract the sampling cylinder 9 after sampling is completed.

[0031] The auxiliary plate 11 is located above the sampling plate 1, and an electric push rod 12 is provided inside it. The bottom movable end of the electric push rod 12 is provided with a push plate 13, which is located above the clearance groove 2. When the push plate 13 enters the clearance groove 2, it cooperates with the mounting plate 8 to push the open end of the sampling tube 9 out of the guide hole 6.

[0032] In this embodiment, the push plate 13 has a second clearance groove 14 in the middle, which corresponds to the position of the partition 4. When the electric push rod 12 is started, the push plate 13 will slowly move downward and enter the first clearance groove 2 in the middle of the sampling plate 1. At this time, the partition 4 will enter the second clearance groove 14.

[0033] The lower sides of the push plate 13 are sloped, and a force-bearing inclined plate 15 is provided on one side of the mounting plate 8 to cooperate with the sloped sides of the push plate 13. When the push plate 13 moves downward into the clearance groove 2, the sloped sides of its two side walls will contact the force-bearing inclined plate 15 and apply force to it. Since the open end of the sampling tube 9 is inserted into the guide hole 6 at the corresponding position, when the push plate 13 applies force to the force-bearing inclined plate 15, the force-bearing inclined plate will push the mounting plate 8 and the sampling tube 9 towards the guide hole 6, while stretching the return spring 10. As the push plate 13 continues to descend, the length of the sampling tube 9 extending out of the guide hole 6 will gradually increase, and samples will be collected from the soil outside the guide hole 6 at the same time.

[0034] After soil sample collection is completed, the electric push rod 12 drives the push plate 13 to slowly rise back to the initial position; at this time, the sampling cylinder 9, under the pulling force of the reset spring 10, will return to the clearance groove along the guide hole 6. It should be noted that one reset spring 10 is provided on each side of the force-bearing inclined plate 15, which can maintain the force balance of the mounting plate 8 during the reset process.

[0035] In addition, a handle 16 is provided on each of the top two sides of the auxiliary plate 11. By holding the handles 16, the staff can maintain the balance of the entire sampling device during the process of the cone plate 7 entering the soil. A support plate 17 is provided on each of the top two sides of the sampling plate 1. The support plate 17 is located below the handles 16, which allows the staff to apply force by stepping on it or by using external tools to apply force to the sampling plate 1, so that the cone plate 7 and the sampling components can smoothly enter the soil. The cone plate 7 has a relief groove 3 18 inside, which corresponds to the position of the push plate 13. The electric push rod 12 drives the push plate 13 to move downward into the relief groove 3 18, which can ensure that the length of each sampling tube 9 extending out of the guide hole 6 is consistent.

[0036] In actual use, the staff moves the collection device into the soil with the cone plate 7 facing downwards, and applies force to the support plate 17 to slowly lower the cone plate 7 and the sampling plate 1 into the soil. The staff can determine the depth of the collection components into the soil by judging the height of the bottom of the support plate 17 from the soil surface, and can adjust and control the depth of the cone plate 7 into the soil to collect samples from soil at different depths.

[0037] This utility model discloses an adjustable sample collection device for soil remediation. By setting a horizontal sampling tube 9 inside the sampling plate 1, and with the cooperation of the push plate 13 at the bottom of the electric push rod 12 and the force-bearing inclined plate 15, the sampling tube 9 passes through the guide hole 6 and is inserted horizontally into the soil. This allows for stratified sampling of soil at different depths, which is convenient for subsequent analysis of the pollution status of soil at different depths. At the same time, it can avoid the influence of samples of different heights on the judgment of the degree of soil pollution. It is very practical and has good market application prospects.

[0038] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. The scope of the present invention is intended to be defined by the claims and their equivalents.
