Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, specifically a soil sampling device for soil remediation. Background Technology

[0002] Soil sampling devices for soil remediation are tools used to collect soil samples, primarily for soil pollution monitoring, remediation effectiveness assessment, and environmental protection. These sampling devices help scientists and environmental workers obtain detailed soil data to analyze pollutant content, nutrient composition, and other factors, thereby developing effective soil remediation plans.

[0003] Existing soil sampling devices, after sampling, use a drive mechanism to move a movable plate downwards, causing the movable plate to push the inner cylinder out from the outer cylinder, and then manually separate the two inner cylinders to remove the soil sample. However, soil is usually composed of particles, and there is a certain degree of adhesion between the particles. This adhesion is still not easy to remove the sample inside the separated inner cylinders. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a soil sampling device for soil remediation.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A soil sampling device for soil remediation, comprising:

[0007] outer cylinder;

[0008] A movable plate is installed inside the outer cylinder, which slides along the axial direction of the outer cylinder and dynamically divides its inner cavity into an upper chamber and a lower chamber;

[0009] Multiple ring-shaped inner plates are distributed in the lower chamber. The top of each inner plate is elastically hinged to the edge of a movable plate, which encloses a cylindrical soil-containing area under normal conditions.

[0010] A drive unit is installed at the top of the outer cylinder, with its drive end extending to the upper chamber and connected to a movable plate. When the drive unit is driven, the movable plate moves down and pushes each inner plate out of the outer cylinder, causing the soil placement area to unfold in a petal shape.

[0011] Once unfolded, the inner plate generates passive shaking through the release of elastic potential energy, and the bottom of the outer cylinder is continuously struck to accelerate the peeling and falling off of the soil attached to the soil-filled area.

[0012] Preferably, the mating sides of adjacent inner plates are complementary curved surfaces, and the complementary curved surfaces form an interference fit to create a sealing strip.

[0013] Preferably, the bottom end of the inner plate has an arc-shaped transition to form an arc-shaped guide surface, and the arc-shaped guide surface and the bottom end of the outer cylinder form a continuous and smooth soil introduction channel.

[0014] Preferably, the edge of the movable plate is provided with several mounting grooves at equal intervals in a ring shape, and the mounting grooves are set at obtuse angles so that the inner plate strikes the bottom end of the outer cylinder when it is unfolded.

[0015] Preferably, the striking part of the inner plate and the bottom end of the outer cylinder form an elastic buffer layer, and the outer surface of the elastic buffer layer and the inner plate are on the same arc surface under normal conditions.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In this invention, the inner plate expands elastically, shakes passively, and strikes continuously, making the soil stripping process efficient and fast. During this process, the elastic shaking generates tiny vibrations, while the continuous striking provides a powerful force. The synergistic effect of the two breaks the adhesion between soil particles, allowing the soil to be easily peeled off from the inner plate and fall off. Attached Figure Description

[0025] Example

[0026] like Figures 1-4As shown, a soil sampling device for soil remediation includes:

[0027] outer cylinder 1;

[0028] A movable plate 2 is installed inside the outer cylinder 1, which slides along the axial direction of the outer cylinder 1 and dynamically divides its inner cavity into an upper chamber and a lower chamber;

[0029] Multiple annular inner plates 3 are distributed in the lower chamber. The top of each inner plate 3 is elastically hinged to the edge of the movable plate 2, which encloses a cylindrical soil-containing area under normal conditions.

[0030] The edge of the movable plate 2 is provided with several mounting grooves 21 at equal intervals. The mounting grooves 21 are set at obtuse angles. When the inner plate 3 is unfolded, it strikes the bottom of the outer cylinder 1. The top of each inner plate 3 is hinged in the mounting groove 21, and a torsion spring is sleeved at the hinge.

[0031] The driving component 4 is set at the top of the outer cylinder 1. Its driving end extends to the upper chamber and is connected to the movable plate 2. When the driving component 4 is driven, the movable plate 2 moves down and pushes each inner plate 3 out of the outer cylinder 1, so that the soil placement area unfolds in a petal shape.

[0032] The unfolded inner plate 3 generates passive shaking through the release of elastic potential energy and continuous knocking at the bottom of the outer cylinder 1 to accelerate the peeling and falling of the soil attached to the soil placement area.

[0033] The existing technology of connecting the top edge of the outer cylinder 1 to an externally rotatable and telescopic structure allows the rotating outer cylinder 1 to be inserted into the ground to remove soil. After removal, the drive component 4 is activated. The drive component 4 is a pneumatic cylinder, and the bottom of its piston rod is connected to a movable plate 2. When the pneumatic cylinder is activated, the piston rod pushes the movable plate 2 axially within the lower chamber. The drive component 4 can also be an electric lead screw or other device that can move the movable plate 2 axially. When the movable plate 2 moves to the top parallel to the bottom of the outer cylinder 1, each inner plate 3 is instantly released and unfolded in a petal shape by a torsion spring. After unfolding, the inner plates 3 will produce a swinging or vibrating motion due to the elastic restoring force of the torsion spring, and will generate intermittent impacts with the shaking. Due to the elastic action of the torsion spring and the internal shaking, the unfolded inner plates 3 will periodically and continuously strike the bottom of the outer cylinder 1. Each shaking process will cause the outer wall of the inner plate 3 to collide with the bottom of the outer cylinder 1, thereby generating a striking force. This repeated tapping process generates a periodic, strong force that effectively overcomes the adhesion between the soil and the inner plate 3, causing the soil particles attached to the surface of the inner plate 3 to be gradually peeled off and fall off.

[0034] When the shaking and striking of the inner plate 3 acts on the soil surface, it directly affects the adhesion of soil particles. Soil is usually composed of particles, and there is a certain degree of adhesion between the particles. This adhesion determines whether soil particles are easy to detach. The continuous shaking and striking of the inner plate 3 exacerbates the loosening between soil particles. Each strike subjects the soil particles to a small impact force for a short period of time, which gradually breaks down the bonds between the particles. As the shaking continues, the soil particles will gradually detach from the inner plate 3 due to the continuous impact. When the inner plate 3 is continuously struck at the bottom of the outer cylinder 1 in an irregular shaking state, they act together on the soil surface. The small impact force caused by shaking and the larger impact force from striking are superimposed, which continuously weakens the soil adhesion and accelerates the peeling process. This effect is similar to repeatedly striking an attached object, which can peel it off and accelerate its detachment.

[0035] like Figure 2 As shown, the mating sides of adjacent inner plates 3 are complementary curved surfaces, and an interference fit is formed between the complementary curved surfaces to create a sealing strip. The sealing strip formed by the sides of the inner plates 3 can effectively prevent soil leakage or uneven distribution, ensuring the integrity of the soil sample.

[0036] like Figure 4 As shown, the bottom end of the inner plate 3 has an arc-shaped transition, forming an arc-shaped guide surface. This arc-shaped guide surface and the bottom end of the outer cylinder 1 constitute a continuous and smooth soil introduction channel. An elastic buffer layer is formed between the striking part of the inner plate 3 and the bottom end of the outer cylinder 1, and the outer surface of the elastic buffer layer and the inner plate 3 are on the same arc-shaped surface under normal conditions. The arc-shaped transition at the bottom end of the inner plate 3, forming a continuous guide surface with the bottom end of the outer cylinder 1, allows the soil to be smoothly introduced into the soil placement area. The elastic buffer layer at the bottom reduces the transmission of impact force and protects the inner plate 3 and the outer cylinder 1. The buffer layer is made of materials such as rubber, which can both protect and amplify vibration. The presence of the buffer layer effectively reduces the reaction force generated during the striking process, preventing damage to the bottom end of the inner plate 3 or the outer cylinder 1, and also reducing excessive impact on soil particles, maintaining balance during the sampling process.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
