Description

Technical Field

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

[0002] Soil stratification sampling is a method for selectively obtaining soil samples from different depths. Soil is a complex medium with a vertically stratified structure, and different layers of soil often exhibit significant differences in physical, chemical, and biological properties. Therefore, existing soil testing processes require the use of stratified samplers for soil sampling.

[0003] However, in existing technologies, traditional soil stratification sampling methods require multiple steps, as well as sample transfer and packaging operations, which are relatively complex and cumbersome, leading to reduced sampling efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the traditional soil stratification sampling method in the prior art requires multiple steps, as well as sample transfer and packaging, which is complicated and cumbersome, resulting in reduced sampling efficiency. Therefore, this invention proposes a stratification sampler for soil testing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stratified sampler for soil testing, comprising a stratified sampling component, a support component at the bottom of the stratified sampling component, a storage component on the outer side of the stratified sampling component, the stratified sampling component comprising a threaded rod, an auger connected to the bottom of the threaded rod, a connecting plate threadedly connected to the middle of the threaded rod, an mounting plate fixedly installed on the outer wall of the connecting plate, the storage component comprising a sleeve, a plurality of sampling ports opened on the side of the sleeve, a storage box being fitted at one end of each sampling port, a connecting strip connected to the side of the storage box, and a cover plate connected to one end of the connecting strip.

[0006] Preferably, the support assembly includes a support base plate, on the top of the support base plate are symmetrically mounted cylinders, the two ends of the cylinders are connected to connecting blocks, and the sides of the connecting blocks are mounted with side support blocks.

[0007] Preferably, the bottom of both the side support block and the support base plate are provided with multiple fixing nails, and the sleeve is installed on the top of the support base plate.

[0008] Preferably, guide rods are symmetrically installed on the top of the support base plate, and one end of the guide rods passes through the interior of the mounting plate.

[0009] Preferably, a connecting plate is connected to the top of the threaded rod, and handles are symmetrically installed on the outer wall of the connecting plate.

[0010] Preferably, the support base plate has a through groove inside, through which the threaded rod and auger pass.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the operator holds the handle and rotates the connecting plate, which in turn drives the threaded rod to rotate. This causes the threaded rod to drive the auger downwards into the soil, ensuring full contact between the auger and the soil. Then, pulling the handle upwards causes the mounting plate and the auger to rise synchronously. The guide rod provides guidance, allowing the soil in contact with the auger to enter the sleeve. The layered sampling component then tilts towards the sampling port, causing different layers of soil inside the sleeve to enter the storage box. The storage box facilitates the storage of different soil layers. The storage box is then removed from the sampling port, and the cover is placed over the opening of the storage box. This allows for the direct classification and storage of the layered soil, facilitating subsequent transportation and effectively preventing mixing and contamination between different soil layers.

[0013] 2. In this utility model, by controlling the cylinder to extend and retract, the cylinder pushes the connecting block to move the side support block to both sides, and then the fixing nails at the bottom of the side support block and the support base plate are inserted into the soil. This helps to ensure the stability of the stratified sampling component. During the soil sampling process, it ensures that the stratified sampling component is inserted vertically into the soil, avoiding tilting of the stratified sampling component and thus avoiding sampling deviation, improving the accuracy of sampling, and thus ensuring the accuracy and reliability of soil testing. At the same time, it avoids soil mixing caused by the instability of the stratified sampling component, which helps to ensure the stability of stratified sampling. When sampling is not required, the cylinder retracts to move the side support block to both sides of the support base plate, reducing space occupation. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figure 1-5 As shown, this utility model provides a stratified sampler for soil testing, including a stratified sampling component 1, a support component 2 at the bottom of the stratified sampling component 1, and a storage component 3 on the outer side of the stratified sampling component 1. The stratified sampling component 1 includes a threaded rod 101, with an auger 106 connected to the bottom of the threaded rod 101, a connecting plate 105 threadedly connected to the middle of the threaded rod 101, and an mounting plate 104 fixedly installed on the outer wall of the connecting plate 105. The storage component 3 includes a sleeve 301, with multiple sampling ports 302 opened on the side of the sleeve 301. A storage box 303 is fitted at one end of each sampling port 302, and a connecting strip 304 is connected to the side of the storage box 303. A cover plate 305 is connected to one end of the connecting strip 304. Guide rods 107 are symmetrically installed on the top of the support base plate 201, with one end of the guide rod 107 penetrating the interior of the mounting plate 104. A connecting plate 102 is connected to the top of the threaded rod 101, and handles 103 are symmetrically installed on the outer wall of the connecting plate 102.

[0024] The overall effect of Embodiment 1 is as follows: the operator holds the handle 103 and rotates the connecting plate 102, which in turn drives the threaded rod 101 to rotate. This causes the threaded rod 101 to drive the auger 106 downward spiraling into the soil, ensuring that the auger 106 makes full contact with the soil. Then, pulling the handle 103 upward causes the mounting plate 104 and the auger 106 to rise synchronously. The guide rod 107 provides guidance, allowing the soil in contact with the auger 106 to enter the sleeve 301. The layered sampling component 1 then tilts towards the sampling port 302, causing different layers of soil inside the sleeve 301 to enter the storage box 303. The storage box 303 facilitates the storage of different layers of soil. The storage box 303 is then removed from the sampling port 302, and the cover plate 305 is placed over the opening of the storage box 303. This facilitates the direct classification and storage of the layered soil, making subsequent transportation easier and effectively preventing mixing and contamination between different layers of soil.

[0025] Example 2, as Figure 1-5 As shown, the support assembly 2 includes a support base plate 201. Cylinders 202 are symmetrically mounted on the top of the support base plate 201. Connecting blocks 203 are connected to both ends of the cylinders 202. Side support blocks 204 are mounted on the sides of the connecting blocks 203. Multiple fixing nails 205 are distributed on the bottom of both the side support blocks 204 and the support base plate 201. A sleeve 301 is installed on the top of the support base plate 201. A through groove is opened inside the support base plate 201. The threaded rod 101 and the auger 106 pass through the through groove.

[0026] The overall effect of Embodiment 2 is as follows: before using the stratified sampling component 1, the cylinder 202 is controlled to extend and retract, causing the cylinder 202 to push the connecting block 203 to move the side support block 204 to both sides. Then, the side support block 204 and the fixing nails 205 at the bottom of the support base plate 201 are inserted into the soil, which helps to ensure the stability of the stratified sampling component 1. During the soil sampling process, the stratified sampling component 1 is ensured to be inserted vertically into the soil, avoiding tilting of the stratified sampling component 1 and thus avoiding sampling deviation, improving the accuracy of sampling, and thus ensuring the accuracy and reliability of soil testing. At the same time, it avoids soil mixing caused by the instability of the stratified sampling component 1, which helps to ensure the stability of stratified sampling. When sampling is not required, the cylinder 202 retracts to drive the side support block 204 to be stored on both sides of the support base plate 201, reducing the space occupied.

[0027] Working principle: When using this device, firstly, before using the stratified sampling component 1, the control cylinder 202 extends and retracts, causing the cylinder 202 to push the connecting block 203, which in turn moves the side support block 204 to both sides. This allows the side support block 204 and the fixing nails 205 at the bottom of the support plate 201 to insert into the soil, ensuring the stability of the stratified sampling component 1. Then, the operator holds the handle 103 and rotates the connecting plate 102, which in turn drives the threaded rod 101 to rotate. This causes the threaded rod 101 to drive the auger 106 downwards into the soil, ensuring full contact between the auger 106 and the soil interior. Pulling the handle 103 upwards causes the mounting plate 104 and the auger 106 to rise synchronously. The guide rod 107 provides guidance, allowing the soil in contact with the auger 106 to enter the sleeve 301. Then, the stratified sampling component 1 tilts towards the sampling port 302, causing different layers of soil inside the sleeve 301 to enter the storage box 303. The storage box 303 facilitates the storage of different layers of soil. The storage box 303 is then removed from the sampling port 302, and the cover plate 305 is placed over the opening of the storage box 303, making it convenient to directly classify and store the stratified soil.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
