Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a soil sampling device for ecological restoration. Background Art

[0002] Soil sampling is a very important step in ecological restoration projects. It can help determine the nature, quality and degree of pollution of the soil, thereby providing important basis and guidance for subsequent ecological restoration work. Through the analysis of soil sampling, we can understand the nutrients, organic matter content, heavy metal content and other information in the soil, providing a scientific basis for subsequent ecological restoration work.

[0003] With the continuous destruction of the ecological environment and the destruction of the soil, the existing soil detection devices are very difficult to operate when testing and sampling the soil due to the high hardness of the soil. This will consume a lot of time and increase the difficulty of sampling. When sampling, the sampled soil is easy to get stuck in the sampling device and is not easy to take out, which increases the difficulty of sampling. The operation during sampling is very strenuous, which greatly increases the workload of the samplers.

[0004] In the prior art, a Chinese patent for a soil sampling device for ecological restoration (publication number CN212007878U) is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: sampling is achieved by rotating the handle, which is simple and convenient to operate and does not require a lot of effort, thereby reducing the labor burden of the staff. After sampling, the sampled soil is taken out by pushing the push piece. The process is simple to operate, and even women with little strength can complete the sampling. The device is simple to operate and easy to carry. However, in actual use, the technical solution can only take one sample at a time. In actual operation, the collection of samples usually requires setting up multiple groups of controls to make the detection process more objective. The device cannot collect soil samples in groups at different positions, so that the soil detection process lacks a control group. If multiple groups are required, the samples must be taken repeatedly, which affects the sampling efficiency and is not conducive to practical application. Summary of the invention

[0005] The purpose of the utility model is to provide a soil sampling device for ecological restoration to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

When installing, the collection tube can be contacted with the docking ring and the internal threaded tube can be screwed on.

[0013] A further improvement of the technical solution of the utility model is that a mark corresponding to the position of the sample storage cavity is arranged on one side of the annular rotating plate away from the docking ring.

[0014] By adopting the above technical solution, when the soil sample is contained in the sample storage cavity, it is possible to determine whether the discharge port is facing the sampling port.

[0015] A further improvement of the technical solution of the utility model is that the collecting tube is set to transparent plastic.

[0016] The adoption of the technical solution makes it easy to observe the situation of the soil sample in the collection tube from the outside.

[0017] A further improvement of the technical solution of the utility model is that a notch is provided on one side of the fixing block, the notch is configured as a through groove, and a handle is fixedly connected to one side of the pressing block.

[0033] like Figure 1 and Figure 2 As shown, the utility model provides a soil sampling device for ecological restoration, including a fixed block 1; a sliding rod 8 is slidably connected to one side of the fixed block 1, and a pressure block 3 is fixedly connected to one end of the sliding rod 8, and the end of the sliding rod 8 away from the pressure block 3 extends to the other side of the fixed block 1 and is fixedly connected to a limiting block 9, a spring 10 is sleeved on the outer side of the sliding rod 8, and a sleeve 4 is fixedly connected to one side of the fixed block 1, and a discharge port 11 is opened on one side of the sleeve 4, and a main shaft 2 is rotatably connected to one side of the pressure block 3, and one end of the main shaft 2 extends to the other side of the pressure block 3 and is fixedly connected to a turning handle 6, and the end of the main shaft 2 away from the turning handle 6 penetrates the fixed block 1 and extends to the inside of the sleeve 4 and is fixedly connected to an auger 5, and the auger 5 is used in conjunction with the sleeve 4, the main shaft 2 is slidably connected to the fixed block 1, and a collecting component for collecting soil samples is arranged on the outer side of the sleeve 4.

[0034] In this embodiment, by providing a sleeve 4 with a discharge port 11 and a collecting tube 14 that can rotate and switch the collecting position, multiple groups of soil samples can be collected simultaneously during sampling to form a reference sample, thereby improving the objectivity of the sample data. A main shaft 2 that can rotate relative to the pressing block 3 and slide relative to the fixed block 1 is provided, so that the auger 5 can move flexibly as needed, and the auger 5 can be retracted into the sleeve 4 when no sampling is performed, so as to avoid damage to the auger 5 or injury to the operator, which greatly facilitates practical applications.

[0035] Example 2

[0036] like Figure 3 and Figure 4As shown, based on Example 1, the utility model provides a technical solution: preferably, the collecting component includes a collecting tube 14, a plurality of sample storage chambers 17 are arranged in the collecting tube 14, a sampling port 18 for use with the discharge port 11 is opened on one side of the sample storage chamber 17, and a movable adapter component is arranged between the fixed block 1 and the collecting tube 14.

[0037] In this embodiment, the discharge port 11 can correspond to different sampling ports 18 so that the soil can be sent to different sample storage chambers 17, which is convenient for collecting multiple groups of soil samples and performing comparative reference detection.

[0038] Example 3

[0039] like Figure 2 and Figure 5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the movable adapter assembly includes an annular rotating plate 12, which is rotatably connected to the side of the fixed block 1 close to the sleeve 4, and the side of the annular rotating plate 12 away from the fixed block 1 is fixedly connected with a docking ring 13, and the outer side of the docking ring 13 is provided with a thread, and the outer side of the collection tube 14 is provided with a limiting ring 15, and the outer side of the collection tube 14 is sleeved with an internal threaded tube 16, and the internal threaded tube 16 is used in conjunction with the docking ring 13.

[0040] In this embodiment, the collection tube 14 is disconnected from the docking ring 13 by rotating the internal threaded tube 16 relative to the docking ring 13, thereby facilitating the removal of the internal threaded tube 16, so that the collection tube 14 can be removed. When installing, the collection tube 14 can be brought into contact with the docking ring 13 and the internal threaded tube 16 can be screwed on.

[0041] like Figure 1 As shown, preferably, a mark corresponding to the position of the sample storage cavity 17 is provided on the side of the annular rotating plate 12 away from the docking ring 13 .

[0042] In this embodiment, when the soil sample is contained in the sample storage cavity 17 , it is also possible to determine whether the discharge port 11 is facing the sampling port 18 .

[0043] Preferably, the collecting tube 14 is made of transparent plastic.

[0044] In this embodiment, it is convenient to observe the condition of the soil sample in the collection tube 14 from the outside.

[0045] like Figure 1 As shown, preferably, a notch 19 is provided on one side of the fixing block 1 , and the notch 19 is configured as a through groove, and a handle 7 is fixedly connected to one side of the pressing block 3 .

[0046] In this embodiment, it is convenient to hold the fixing block 1 and reduce the distance between the fixing block 1 and the pressing block 3 by holding the handle 7 .

[0047] like Figure 2 As shown, preferably, the auger 5 is slightly smaller in length in the axial direction than the sleeve 4 .

[0048] In this embodiment, under normal conditions, the auger 5 is completely retracted into the sleeve 4, which can protect the auger 5 and prevent the auger 5 from causing harm to personnel.

[0049] The working principle of the soil sampling device for ecological restoration will be described in detail below.

[0050] like Figure 1-5 As shown, before sampling, the collection tube 14 is rotated so that the discharge port 11 can be observed through the transparent collection tube 14 to face one of the sampling ports 18; when sampling, the sleeve 4 is directed downward and in contact with the ground, and the notch 19 of the holding block 1 is held and the handle 7 is held and pressed at the same time, so that the spring 10 is squeezed and the main shaft 2 is driven to slide relative to the fixing block 1, thereby driving the auger 5 to extend out of the sleeve 4 (due to contact with the ground, the sleeve 4 moves upward relative to the auger 5, and the auger 5 remains in contact with the ground), and the turning handle 6 is turned so that the main shaft 2 rotates. The screw drill 5 is driven to rotate to dig the soil until the sleeve 4 touches the ground. At this time, the fixed block 1 can be released and the handle 6 can be continuously rotated until the soil is sent to the position of the discharge port 11, so that the soil is squeezed into the corresponding sample storage cavity 17 to complete the collection. The operator can observe the collection situation through the transparent collection tube 14. After the collection is completed, the handle 6 is rotated in the opposite direction to release the excess soil, and the collection tube 14 is rotated so that the discharge port 11 is facing the next sampling port 18, and multiple groups of soil samples can be collected by moving to other collection points.

[0051] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
