Description

Technical Field

[0001] This utility model is a sampling device for stratigraphic exploration of contaminated sites, belonging to the technical field of exploration and sampling equipment. Background Technology

[0002] In environmental monitoring of contaminated sites, it is necessary to sample and test the soil on site using a soil sampler. The soil sampler is used to lift the original soil from the lower layer as a sample to understand its properties. In order to better understand the properties of the base layer, and in engineering geological exploration and investigation, in order to obtain the physical and mechanical properties of the foundation soil, it is sometimes even necessary to take the original soil sample from a deeper depth. This kind of soil sampling equipment is called a soil sampler.

[0003] Publication number CN219200907U mentions a soil sampling device. Through its impact guide and impact component, it allows for easier sampling insertion, especially in hard soil conditions, by providing auxiliary hammering force and avoiding the need for manual insertion. The impact guide shaft also helps guide the sliding counterweight, preventing it from falling and ensuring safety. It also avoids the risk of finger injuries from hammer blows. However, the impact component requires manual lifting during hammering, which is time-consuming and laborious, particularly in hard, contaminated soil. Therefore, there is an urgent need for a soil sampling device for contaminated soil exploration to address these issues. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sampling device for the exploration of strata in contaminated sites, so as to solve the problems mentioned in the background technology. This utility model adopts an electrically driven auxiliary hammer structure, which can quickly insert the soil sampler into the strata of relatively hard contaminated sites for exploration and sampling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for stratigraphic exploration of contaminated sites, comprising a vertical support base, a vertical adjustment frame, an elliptical swing plate, a hammer piston head, and a soil sampling cylinder. Multiple vertical poles are longitudinally fixed to the upper end of the vertical support base, and a fixing plate is horizontally fixed to the upper end of each of the vertical poles. An electric hydraulic rod is longitudinally mounted on the lower end of each fixing plate. The vertical adjustment frame is suspended between the multiple vertical poles, and the movable end of each electric hydraulic rod is fixed to the vertical adjustment frame. A servo motor is installed on the upper left side inside the vertical adjustment frame, and a fixing lug is fixed in the middle of the upper part of the vertical adjustment frame. A servo motor shaft is provided at its end, and the rotating shaft moves through a fixed lug plate. The elliptical swing plate is located inside the fixed lug plate and is fixedly sleeved outside the rotating shaft. A movable connecting rod is movably provided at the other end of the elliptical swing plate. The lower end of the movable connecting rod is movably connected to a fixed shaft. The hammer piston head is fixed outside the fixed shaft. A piston guide block is suspended and fixed inside the vertical adjustment frame. A positioning base plate is horizontally fixed at the lower end of the vertical adjustment frame. A guide cylinder is longitudinally fixed at the upper end of the vertical support base. The soil sampling cylinder is longitudinally located inside the guide cylinder. A hammer top plate is horizontally fixed at the upper end of the soil sampling cylinder. An annular cutter is integrally provided at the lower end of the soil sampling cylinder.

[0006] Furthermore, guide sleeves are slidably fitted onto the outside of each of the multiple uprights, and the other end of each guide sleeve is fixed to the vertical adjustment frame.

[0007] Furthermore, the hammering piston head slides through the piston guide block, and the hammering piston head is positioned directly above the hammering top plate.

[0008] Furthermore, a circular groove is provided in the middle of the lower end of the positioning base plate, and the guide cylinder is located directly below the circular groove. Guide slide rods are longitudinally fixed on both the left and right sides of the lower end of the positioning base plate.

[0009] Furthermore, both guide rods slide through the vertical support base.

[0010] Furthermore, two lifting rods are horizontally welded to the side surface of the soil sampling cylinder.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a sampling device for strata exploration in contaminated sites. Because it incorporates an electric hydraulic rod, a vertical adjustment frame, a servo motor, a fixed lug plate, a rotating shaft, an elliptical swing plate, a movable connecting rod, a fixed shaft, a hammer piston head, a piston guide block, a guide cylinder, a soil sampling cylinder, a ring cutter, and a hammer top plate, our design improvements and practical use have shown that this device has a reasonable structure and good practicality. The electric-driven auxiliary hammering structure enables the soil sampler to be quickly inserted into harder contaminated strata for exploration and sampling. Furthermore, the overall operation is time-saving and labor-saving, effectively reducing the workload of exploration and sampling personnel. Attached Figure Description

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3This utility model provides a technical solution: a sampling device for stratigraphic exploration of contaminated sites, including a vertical support base 1, a vertical adjustment frame 5, an elliptical swing plate 9, a hammer piston head 12, and a soil sampling cylinder 16. Multiple vertical rods 2 are longitudinally fixed to the upper end of the vertical support base 1, and a fixing plate 3 is horizontally fixed to the upper end of each of the vertical rods 2. An electric hydraulic rod 4 is longitudinally installed at the lower end of each fixing plate 3. The vertical adjustment frame 5 is suspended between the multiple vertical rods 2, and the movable end of the electric hydraulic rod 4 is fixed to the vertical adjustment frame 5. A servo motor 6 is installed on the upper left side inside the vertical adjustment frame 5, and a fixing ear plate 7 is fixed in the middle of the upper end inside the vertical adjustment frame 5. A rotating shaft 8 is provided at the shaft end of the servo motor 6, and the rotating shaft 8 moves through the fixing ear plate 7. The elliptical swing plate 9 is located at the fixing ear plate. Inside 7, and fixedly sleeved outside the rotating shaft 8, the other end of the elliptical swing plate 9 is movably connected to a movable connecting rod 10, the lower end of the movable connecting rod 10 is movably connected to a fixed shaft 11, the hammer piston head 12 is fixed outside the fixed shaft 11, the piston guide block 13 is suspended and fixed inside the vertical adjustment frame 5, the lower end of the vertical adjustment frame 5 is horizontally fixed to a positioning base plate 14, the upper end of the vertical support base 1 is longitudinally fixed to a guide cylinder 15, the soil sampling cylinder 16 is longitudinally located inside the guide cylinder 15, the upper end of the soil sampling cylinder 16 is horizontally fixed to a hammer top plate 18, and the lower end of the soil sampling cylinder 16 is integrally provided with a ring cutter 17. This design solves the problem that in the original device, the impact component needs to be manually lifted back and forth when hammering, which is time-consuming and laborious, and is extremely inconvenient in hard polluted soil strata.

[0019] As the first embodiment of this utility model: multiple uprights 2 are slidably fitted with guide sleeves on their exteriors, and the other ends of the multiple guide sleeves are fixed to the vertical adjustment frame 5. By adding multiple guide sleeves and fixing the other ends of them to the vertical adjustment frame 5, the vertical adjustment frame 5 is moved more smoothly in the up and down direction between the multiple uprights 2, and there will be no deviation or shaking.

[0020] The hammer piston head 12 slides through the piston guide block 13, and is located directly above the hammer top plate 18. The added hammer piston head 12 can drive the hammer to strike the hammer top plate 18, causing the soil sampling cylinder 16 to move downwards for soil sampling. A circular groove is formed in the middle of the lower end of the positioning base plate 14, and the guide cylinder 15 is located directly below the circular groove. Guide slide rods 20 are longitudinally fixed on both the left and right sides of the lower end of the positioning base plate 14. Both guide slide rods 20 slide through the vertical support base 1. Through the added guide slide rods 20, they can slide along with the vertical adjusting frame 5 as it moves up and down among the multiple uprights 2. Two lifting rods 19 are horizontally welded to the side surface of the soil sampling cylinder 16. These two lifting rods 19 facilitate the extraction and removal of the soil sampling cylinder 16 by the surveying and sampling personnel.

[0021] As a second embodiment of this utility model: After selecting a suitable sampling location for the contaminated site, the device is placed longitudinally, so that the soil sampling cylinder 16 is longitudinally positioned within the guide cylinder 15, and the annular cutter 17 is directly facing the sampling location of the contaminated site. Then, the servo motor 6 is started, which drives the rotating shaft 8 to rotate. The rotation of the rotating shaft 8 will drive the elliptical swing plate 9 to rotate and swing. In this way, the movable connecting rod 10 and the fixed shaft 11 can drive the hammering piston head 12 to perform reciprocating hammering operations in the up-down direction (because the hammering piston head 12 is limited to the piston guide block 13, it will not swing in other directions when performing reciprocating hammering operations in the up-down direction). During this process, the hammering piston head 12 will hammer the top plate 1 through the circular groove. 8. Continuous hammering causes the hammer top plate 18 to move downward within the guide cylinder 15, thereby driving the soil sampling cylinder 16 and the annular cutter 17 to cut and sample soil downwards. After the hammering piston head 12 hammers the hammer top plate 18 to its maximum extent, the movable end of the electric hydraulic rod 4 is extended downwards, which drives the vertical adjusting frame 5 and its internal components to move downwards collectively. This forces the hammering piston head 12, which is hammering downwards, to re-contact the hammer top plate 18, allowing it to continue hammering the hammer top plate 18. This allows the soil sampling cylinder 16 and the annular cutter 17 to continue cutting and sampling soil downwards. The process is quick and convenient. The entire system is controlled by an external power supply and an external controller. Since this is existing technology, the circuit connection method will not be described in detail.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
