Description

Technical Field

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

[0002] Soil remediation is a crucial step in treating contaminated soil and restoring its ecological functions, and accurate sampling is fundamental for assessing remediation effectiveness and developing treatment plans. Current soil remediation sampling technologies mainly fall into two categories:

[0003] Traditional manual sampling: This method uses handheld drilling tools or shovels to collect surface or shallow soil samples. Its advantage lies in its high flexibility, but it has significant drawbacks, such as: reliance on manual operation, making it difficult to meet the sampling needs of large-scale remediation projects; the ease with which cross-contamination of samples can occur if tools are not thoroughly cleaned; and the inability to separate soil particles of different sizes during collection, requiring additional sieving steps and increasing the testing cycle.

[0004] In summary, a sampling device for soil remediation is needed to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a sampling device for soil remediation, which aims to solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for soil remediation, comprising a main body and a spiral material-collecting component. The main body includes a tube, a feeding tray, and a top cover. The feeding tray is installed at the top of the tube, and the top cover is installed on the feeding tray. The feeding tray is used to install a material guiding component. The main body is equipped with a drive mechanism, a material guiding component, a turnover mechanism, and a dispensing box. The drive mechanism drives the spiral material-collecting component to rotate. The material guiding component transfers the sampled soil inside the feeding tray to the turnover mechanism. The turnover mechanism intermittently flips the sampled soil into the dispensing box, and the dispensing box is used to dispense the sampled soil. The material guiding component enables automatic soil particle grading, and the intermittent turnover mechanism controls the feeding rhythm, ensuring uniform dispensing quantity. The dispensing box avoids cross-contamination. The spiral material collection, material guiding, sorting, and dispensing processes are fully automated, reducing manual intervention. The overall modular structure integrates the drive, material guiding, and dispensing components, resulting in a compact layout and easy maintenance. This significantly improves the efficiency, accuracy, and standardization of soil sampling, making it suitable for large-scale remediation projects.

[0007] Furthermore, the drive mechanism is fixedly installed on the top cover. The drive mechanism includes a drive motor, a coupling, and a pusher blade. The bottom drive end of the motor passes through the top cover and is connected to the pusher blade and the spiral material handling component through the coupling.

[0008] Furthermore, the material guiding assembly includes a first discharge port, a first material guiding pipe, a second discharge port, and a second material guiding pipe. The first discharge port and the second discharge port are located on the feeding plate. The first material guiding pipe and the second material guiding pipe are respectively connected to the first discharge port and the second discharge port. The first discharge port is used to conduct large particles of soil, and the second discharge port is used to filter and conduct small particles of soil.

[0009] Furthermore, the turnover mechanism includes a first motor, a first turnover roller, a second motor, a second turnover roller, and a support. The first motor and the second turnover roller are both connected to the tube body through the support. The output end of the first motor is connected to the first turnover roller, and the output end of the second motor is connected to the second turnover roller.

[0010] Furthermore, the material distribution box includes a base, a box body, an upper cover plate, a hopper, and a dispensing assembly. The box body is connected to the tube body through the base. The upper cover plate and the hopper are installed on the box body. The hopper is located directly below the first and second rotating rollers.

[0011] Furthermore, the dispensing assembly includes a dispensing motor, a turntable, and several sampling dispensing containers. The dispensing motor is installed on the bottom wall of the upper cover plate, and the output end of the dispensing motor is connected to the turntable. The turntable has positioning ports on its peripheral sidewalls for nesting and installing the sampling dispensing containers.

[0012] Furthermore, a soil retaining cover is installed on the pipe body, and the soil retaining cover is located between the feeding tray and the turnover mechanism.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this utility model, by setting a double discharge port design for the ground material guide component, the automatic grading of soil particles is realized, reducing subsequent manual screening steps and improving sampling efficiency to a certain extent.

[0015] 2. In this utility model, the soil turnover mechanism is set up with dual motors driving the turnover rollers. The soil falling rhythm is controlled by intermittent flipping action. Combined with the turntable positioning port of the material box and the sampling and dispensing container, it is ensured that each sample is quantitative and independent, avoiding cross-contamination.

[0016] 3. In this utility model, the ground drive mechanism, turnover mechanism and material distribution box are integrated into the pipe body, and the soil retaining cover prevents soil backflow. The overall layout is reasonable and the failure rate is reduced. The dispensing components adopt a modular design, which is easy to disassemble, clean or replace. Moreover, the entire process from spiral material picking, material guiding and sorting to dispensing is driven by a motor, which reduces manual intervention. It is suitable for large-scale soil remediation scenarios, and has both practicality and economy. It has certain use value and promotion value. Attached Figure Description

[0029] As one implementation method, the top cover 103 is an open cover structure, which allows the interior of the feeding tray 102 to be exposed, making it convenient to perform maintenance when the pusher blade 23 inside the feeding tray 102 gets stuck.

[0030] In one embodiment, the material guiding assembly 30 includes a first discharge port 31, a first material guiding pipe 32, a second discharge port 33, and a second material guiding pipe 34. The first discharge port 31 and the second discharge port 33 are opened on the feeding plate 102. The first material guiding pipe 32 and the second material guiding pipe 34 are respectively connected to the first discharge port 31 and the second discharge port 33. The first discharge port 31 is used to conduct large particles of soil, and the second discharge port 33 is used to filter and conduct small particles of soil.

[0031] In one embodiment, the diameter of the first discharge port 31 is larger than that of the second discharge port 33, the diameter of the first guide pipe 32 is larger than that of the second guide pipe 34, and the second discharge port 33 is provided with a porous filter screen. The lower surface wall of the first guide pipe 32 near the turnover mechanism 40 is provided with several crushing ports for discharging fine soil.

[0032] In one embodiment, the turnover mechanism 40 includes a first motor 41, a first turnover roller 42, a second motor 43, a second turnover roller 44, and a support 45. The first motor 41 and the second turnover roller 44 are both connected to the tube body 101 through the support 45. The output end of the first motor 41 is connected to the first turnover roller 42, and the output end of the second motor 43 is connected to the second turnover roller 44.

[0033] In one implementation, the first motor 41, the first rotating roller 42, the second motor 43, and the second rotating roller 44 are arranged symmetrically.

[0034] In one embodiment, the material distribution box 50 includes a base 51, a box body 52, an upper cover plate 53, a hopper 54, and a dispensing assembly 55. The box body 52 is connected to the tube body 101 through the base 51. The upper cover plate 53 and the hopper 54 are installed on the box body 52. ​​The hopper 54 is located directly below the first rotating roller 42 and the second rotating roller 44.

[0035] In one embodiment, the left side of the housing 52 is a door panel, and the door panel is provided with a viewing window for easy observation.

[0036] In one implementation, the top cover 53 covers two-thirds of the top opening of the dispensing box 50, and the bottom outlet of the hopper 54 connects to the interior of the box 52 and is located above the dispensing assembly 55.

[0037] In one embodiment, the first rotating roller 42 and the second rotating roller 44 are located directly below each other, and the circumference of the first rotating roller 42 and the second rotating roller 44 are provided with several receiving troughs of the same size for intermittently turning and receiving soil.

[0038] In one embodiment, the dispensing assembly 55 includes a dispensing motor 551, a turntable 552, and a plurality of sampling dispensing containers 553. The dispensing motor 551 is mounted on the bottom wall of the upper cover plate 53, and the output end of the dispensing motor 551 is connected to the turntable 552. The peripheral side wall of the turntable 552 is provided with a positioning port 5521 for nesting and installing the sampling dispensing containers 553.

[0039] In one implementation, the sampling and dispensing container 553 is a sampling and dispensing tube. When the sampling and dispensing tube is horizontally rotated and its position is adjusted by the structural cooperation of the dispensing motor 551 and the turntable 552, the dispensing motor 551 rotates at the same fixed angle each time, always keeping one sampling and dispensing tube directly below the bottom outlet of the hopper 54.

[0040] In one embodiment, a retaining cover 1011 is installed on the pipe body 101, and the retaining cover 1011 is located between the feeding tray 102 and the turnover mechanism 40.

[0041] The working principle of this utility model is as follows: In use, the drive mechanism 20, in conjunction with the spiral material-collecting component 10, performs soil collection. Specifically, by starting the drive motor 21, the spiral material-collecting component 10 is rotated via the coupling 22, lifting the soil from the bottom of the pipe body 101 to the feeding tray 102. After entering the feeding tray 102, the soil is pushed towards the first discharge port 31 and the second discharge port 33 by the pushing blades 23. Large particles enter the first rotation roller 42 of the turnover mechanism 40 through the first discharge port 31 and the first guide pipe 32, while small particles are individually guided to the turnover machine through the second discharge port 33 and the second guide pipe 34. The second rotating roller 44 of the structure 40 achieves particle grading. Then, the first rotating roller 42 and the second rotating roller 44 are driven to rotate alternately by the first motor 41 and the second motor 43 respectively, intermittently turning the soil into the hopper 54 of the distribution box 50 to ensure uniform feeding. The dispensing motor 551 drives the turntable 552 to rotate, so that the sampling and dispensing containers 553 are aligned with the bottom outlet of the hopper 54 in sequence. The soil falls into the container in the positioning port 5521 of the turntable through the hopper, completing the dispensing. The soil retaining cover 1011 is located between the feeding plate and the rotating mechanism to prevent the soil from falling into the distribution box 50 during the feeding process.

[0042] It should be noted that while the preferred embodiments of this utility model are provided in the specification and accompanying drawings, this utility model can be implemented in many different forms and is not limited to the embodiments described in this specification.
