Description

Technical Field

[0001] This utility model belongs to the field of soil sampling and storage technology, and specifically relates to a soil sampling and storage device for natural resource surveys. Background Technology

[0002] Soil environmental monitoring refers to determining the environmental quality or pollution level and its changing trends by measuring representative values ​​of factors affecting soil environmental quality. Soil monitoring, as we usually refer to it, generally includes technical aspects such as sampling site selection, sample preparation, analytical methods, result characterization, data statistics, and quality evaluation.

[0003] Soil sampling refers to the methods of collecting soil samples, including sampling layout and techniques, and sample storage. Accurate sampling and preservation of samples are crucial for obtaining accurate test data.

[0004] A search revealed a soil sampling and storage integrated device (CN219956965U). In this solution, a collection cylinder is used for sampling, and then a transmission plate pushes the soil out of the collection cylinder and drops it into a collection box for collection. However, during application, when the collection cylinder pushes the collected soil into the collection box, it directly mixes the soil from different depths in the collection cylinder together, making it impossible to accurately distinguish the samples from different soil layers, which in turn reduces the accuracy of the sample test results. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a soil sampling and storage device for natural resource surveys. By inserting a partition plate at the insertion interface of the core tube to isolate the soil sample, soil layers at different depths within the core tube are separated, reducing the probability of soil samples mixing during transportation and improving the accuracy of test results.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A soil sampling and storage device for natural resource surveys includes a support frame, a storage rack, a fixing frame, a lead screw, a core tube, a first motor, a second motor, a bushing, and a support platform. The support frame and the fixing frame are fixed on the support platform. The storage rack is fixed on the fixing frame. The bushing is rotatably connected to the top of the support frame. The first motor is fixed to the top of the support frame, and its output shaft end is provided with a synchronous pulley. The lead screw is threaded to the bushing, and one end of the lead screw is provided with a fixedly connected mounting cylinder. The second motor is fixed inside the mounting cylinder. The shaft end of the second motor is connected to the core tube. The support frame is also provided with a limiting groove, and the mounting cylinder is also provided with a limiting block, which is located in the limiting groove. The end of the bushing is fixedly provided with a synchronous pulley and is connected to the synchronous pulley at the shaft end of the first motor via a synchronous belt. The core tube is provided with several sampling ports and insertion ports, and the arc length of the insertion port is half the circumference of the core tube. The first motor drives the bushing to rotate, which in turn drives the core tube to descend along the limiting groove via the lead screw. The second motor drives the core tube to rotate and drill soil samples.

[0008] The sampling port on the core sampling tube is equipped with a first sealing plate fixed by bolts, and the insertion port is equipped with a second sealing plate fixed by bolts; the core sampling tube is equipped with scale lines to observe the soil sampling depth; the outer wall of the end of the core sampling tube is also equipped with teeth that can loosen the soil layer on the outer wall of the core sampling tube during soil sampling, reducing the friction between the core sampling tube and the soil when the core sampling tube retracts, as well as the resistance of the first sealing plate and the second sealing plate.

[0009] The top of the core-taking cylinder is provided with a plug-in block for plugging into the end of the second motor shaft; the plug-in block is provided with a square hole.

[0010] The second motor shaft end is provided with a connector, the connector is provided with a sliding insert shaft, and the insert shaft end is provided with a second limiting shaft for insertion; the connector is provided with a square hole.

[0011] The insert shaft is designed as a square shaft; the insertion of the insert shaft into the square hole can prevent the core tube from rotating around the insert shaft as the axis.

[0012] The fixed frame is equipped with storage compartments, each with a sealed door. The compartments are used to store partition boards, which are inserted into the insertion interface and fixed with bolts to isolate the soil and reduce the probability of soil from different depths mixing during transportation.

[0013] The storage rack is equipped with several storage cylinders for storing core samples. The end face of the storage rack is equipped with a rotating shaft and a fixed first limiting shaft. The first limiting shaft is located below the rotating shaft, and a first limiting plate is provided on the rotating shaft. A counterweight is provided on the first limiting plate. The counterweight is located at one end of the first limiting plate so that the weight at one end of the first limiting plate is greater than that at the other end. When the first limiting plate rotates and blocks the storage cylinder, it can prevent the core sample from slipping out of the storage cylinder. The use of the counterweight can prevent the first limiting plate from rotating back. The first limiting shaft is used to block and restrict the rotation of the first limiting plate.

[0014] Preferably, the bottom end of the bushing is provided with a second limiting plate.

[0015] Preferably, the support platform is equipped with a battery for power supply.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] This solution allows for the separate storage of core samples via storage tubes on a storage rack. Furthermore, the core samples can be connected to and removed from the connector of the second motor, enabling multiple batches of sampling while ensuring each batch is stored separately to prevent mixing. Additionally, a partition plate can be inserted into the core sampler's interface to isolate the samples within the core sampler, reducing the likelihood of soil from different depths mixing during transport, thereby improving sampling accuracy and the accuracy of subsequent experimental results.

[0031] The sampling port 52 of the core sampling cylinder 5 is provided with a first sealing plate 56 fixed by bolts, and the insertion port 53 is provided with a second sealing plate 57 fixed by bolts; the core sampling cylinder 5 is provided with scale lines 54 to observe the soil sampling depth; the outer wall of the end of the core sampling cylinder 5 is also provided with teeth 55, which can loosen the soil layer on the outer wall of the core sampling cylinder 5 during soil sampling, reduce the friction between the core sampling cylinder 5 and the soil and the resistance of the first sealing plate 56 and the second sealing plate 57 when the core sampling cylinder 5 retracts.

[0032] The core-taking cylinder 5 is provided with a plug-in block 51 at the top for plugging into the end of the shaft of the second motor 7; the plug-in block 51 is provided with a square hole.

[0033] The second motor 7 shaft end is provided with a connector 71, the connector 71 is provided with a sliding insert shaft 72, the end of the insert shaft 72 is provided with a second limiting shaft 73 for insertion; the connector 71 is provided with a square hole.

[0034] The insert shaft 72 is a square shaft; the insertion of the insert shaft 72 into the square hole can prevent the core tube 5 from rotating around the insert shaft 72 as the axis.

[0035] The fixed frame 3 is provided with a storage compartment 31, and the storage compartment 31 is provided with a sealing door 32.
