Description

Technical Field

[0001] This utility model relates to the field of environmental testing technology, and in particular to a deep soil sampling device for environmental testing. Background Technology

[0002] In environmental monitoring, soil sampling is a fundamental step in obtaining key data such as soil pollution status and fertility level. In particular, the analysis of deep soil is crucial. Obtaining representative soil samples that retain their original characteristics is extremely important for assessing the migration patterns and historical pollution status of deep soil. At this time, soil sampling equipment, namely soil sampling drills, is required, which consists of a gasoline-powered engine and a borehole sampling tube.

[0003] Existing soil sampling drills typically involve a person holding the handheld frame while a gasoline-powered engine generates impact force to push the sampling tube into the deep soil for sampling. During this process, the significant vibrations generated by the equipment make it prone to shifting, making it difficult to maintain verticality and causing the sampling tube to tilt into the soil. This can lead to damage or deformation of the sampling tube, as well as inaccurate sampling depth, affecting subsequent testing results. Furthermore, it is inconvenient to use on sloping ground. Utility Model Content

[0004] The purpose of this invention is to address the problems of existing deep soil sampling equipment for environmental testing, which are prone to deviation during sampling, making it difficult to ensure the verticality of the equipment, reducing the accuracy of sampling depth, and being inconvenient for sampling on sloping ground, resulting in low versatility. Therefore, this invention proposes a deep soil sampling equipment for environmental testing.

[0005] To achieve the above objectives, the present invention employs the following technology: a deep soil sampling device for environmental testing, comprising a soil sampling drill, a stabilizing mechanism for improving the stability of the soil sampling drill is provided below the soil sampling drill, a limit rod is provided at the top of the stabilizing mechanism and the limit rod passes through the handheld frame of the soil sampling drill, and horizontal fixing mechanisms for adjusting the level of the soil sampling drill on inclined ground are provided on both sides of the stabilizing mechanism.

[0006] As a further description of the above technical solution: the stabilizing mechanism includes a bottom frame, a lower limit component is provided inside the bottom frame, an upper limit component is provided at the top of the bottom frame, and side plates are fixedly connected to both sides of the top of the bottom frame.

[0007] As a further description of the above technical solution: the lower limit component includes a limit disc, the limit disc is located at the center of the bottom frame, the outer wall of the limit disc is fixedly connected to a connecting strip plate connected to the inner wall of the bottom frame, a limit hole is opened at the center of the limit disc, and the drilling sampling tube on the soil sampling drill passes through the limit hole.

[0008] As a further description of the above technical solution: the lower limit assembly includes an electric push rod fixedly installed on the bottom frame, the telescopic end of the electric push rod is fixedly connected to a top limit plate, the center of the top limit plate is provided with a through hole, and an elastic limit ring is provided in the through hole.

[0009] As a further description of the above technical solution: the elastic limiting ring is made of rubber and is compatible with the borehole sampling tube on the soil sampling drill.

[0010] As a further description of the above technical solution: the horizontal fixing mechanism includes an upper hinge seat and a base plate, and the upper hinge seat is fixed on one side of the side plate. A lower hinge seat is fixedly connected to the top of the base plate. A connecting rod is hinged between the upper hinge seat and the lower hinge seat. Ground nails are inserted on both sides of the top of the base plate.

[0011] As a further description of the above technical solution: the outer wall of the limiting rod is provided with scale lines, and the bottom of the limiting rod is fixed to the connecting strip plate.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This invention, through its stabilizing and horizontal fixing mechanisms, allows the soil sampling drill to operate smoothly. First, the stabilizing mechanism is positioned. Then, based on the inclination of the sampling location, the tilt angle of the connecting rod is flexibly adjusted, thereby adjusting the inclination of the bottom frame to ensure its horizontal position. This allows the device to be used in various environments, expanding its application range and enhancing its versatility. Next, the drilling sampling tube of the soil sampling drill passes sequentially through the elastic limiting ring and limiting hole of the stabilizing mechanism, facilitating simultaneous and stable upper and lower limiting of the drilling sampling tube, ensuring the smooth operation of the soil sampling drill. The machine remains vertical during operation, allowing the soil sampling drill to push the borehole sampling tube vertically into the soil. This ensures the tube is always under vertical force, preventing damage or deformation, and avoids inaccurate sampling depth due to tilted sampling. The tube is then pulled out, completing the sampling of deep soil layers. During the extraction, an electric push rod drives the top limit plate upwards, moving the tube upwards and automatically pulling it out of the soil. This saves time and effort, reduces labor intensity, and further improves sampling convenience. Attached Figure Description

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-3 This embodiment provides a deep soil sampling device for environmental testing, including a soil sampling drill 1. A stabilizing mechanism 2 for improving the stability of the soil sampling drill 1 is provided below the soil sampling drill 1. A limiting rod 4 is provided at the top of the stabilizing mechanism 2, and the limiting rod 4 passes through the handheld frame of the soil sampling drill 1. Horizontal fixing mechanisms 3 for adjusting the level of the soil sampling drill 1 on inclined ground are provided on both sides of the stabilizing mechanism 2. The stabilizing mechanism 2 includes a bottom frame 21, with a lower limit component inside and an upper limit component at the top. Side plates 22 are fixedly connected to both sides of the top of the bottom frame 21. The lower limit component includes a limiting disc 24 located at the center of the bottom frame 21. A connecting strip 23, which connects to the inner wall of the bottom frame 21, is fixedly connected to the outer wall of the limiting disc 24. A limiting hole 25 is formed at the center of the limiting disc 24. The soil sampling drill 1... The drilling sampling tube passes through the limiting hole 25. The lower limiting component includes an electric push rod 26 fixedly installed on the bottom frame 21. The telescopic end of the electric push rod 26 is fixedly connected to the top limiting plate 27. The center of the top limiting plate 27 has a through hole, and an elastic limiting ring 28 is provided in the through hole. The elastic limiting ring 28 is made of rubber and is compatible with the drilling sampling tube on the soil sampling drill 1. The outer wall of the limiting rod 4 is provided with scale lines 5, and the bottom of the limiting rod 4 is fixed on the connecting strip plate 23.

[0017] Specifically, when the soil sampling drill rig 1 is working, a suitable sampling location is selected, the stabilizing mechanism 2 is placed, and the position of the horizontal fixing mechanism 3 is flexibly adjusted according to the inclination of the sampling location. The base plate 32 is fixed with ground nails 35 to enhance stability. The inclination angle of the connecting rod 34 is flexibly adjusted, thereby flexibly adjusting the inclination of the bottom frame 21 to adjust the levelness of the bottom frame 21, so that the bottom frame 21 is in a horizontal state. After the stabilizing mechanism 2 is fixedly installed, the soil sample is then taken. The sampling tube of the soil sampling drill 1 passes sequentially through the elastic limiting ring 28 and the limiting hole 25 of the stabilizing mechanism 2. The limiting rod 4 passes through both ends of the handheld frame of the soil sampling drill 1. The extension and retraction of the electric push rod 26 drives the top limiting plate 27 to move up and down, which in turn drives the elastic limiting ring 28 to move up and down along the sampling tube of the soil sampling drill 1. This allows the elastic limiting ring 28 to limit the upper part of the sampling tube of the soil sampling drill 1 and to limit the lower part of the sampling tube of the soil sampling drill 1 through the limiting hole 25. This achieves simultaneous stable positioning of the soil sampling drill 1 from both above and below, ensuring that the drill 1 remains vertical during operation. This allows the drill 1 to vertically push the sampling tube into the soil. As the sampling tube is continuously pushed in, the electric push rod 26 simultaneously moves the top limiting plate 27 downwards, ensuring smooth insertion into the soil. This ensures the sampling tube remains under vertical force, preventing damage or deformation. This avoids inaccurate sampling depth caused by tilting the borehole sampling tube. The scale line 5 makes it easy to observe the drilling depth of the borehole sampling tube of the soil sampling drill 1. Then, the borehole sampling tube is pulled out, and the sampling of deep soil can be completed. During the pulling process, the electric push rod 26 drives the top limit plate 27 to rise synchronously, which drives the borehole sampling tube to move upward, so that the borehole sampling tube that has penetrated into the soil can be automatically pulled out, saving time and effort, reducing labor intensity, and further improving the convenience of sampling.

[0018] Furthermore, the horizontal fixing mechanism 3 includes an upper hinge seat 31 and a base plate 32. The upper hinge seat 31 is fixed to one side of the side plate 22. A lower hinge seat 33 is fixedly connected to the top of the base plate 32. A connecting rod 34 is hinged between the upper hinge seat 31 and the lower hinge seat 33. Ground nails 35 are inserted on both sides of the top of the base plate 32.

[0019] Specifically, the number of horizontal fixing mechanisms 3 is set to four sets, symmetrically arranged on both sides of the side plate 22, so as to provide stable support for the bottom frame 21. The upper hinge seat 31 and the connecting rod 34, and the lower hinge seat 33 and the connecting rod 34 are all rotatably connected by pins. By adjusting the included angle between the connecting rod 34 and the bottom frame 21, the distance between the bottom plate 32 and the bottom frame 21 can be flexibly adjusted, thereby adjusting the levelness of the bottom frame 21 to keep it in a horizontal state. It is suitable for ground with different inclinations, has strong versatility, and ensures that the soil sampling drill 1 can always be in a vertical state when working, ensuring the accuracy of the sampling depth and making it convenient to use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
