Description

Technical Field

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

[0002] In fields such as soil testing, environmental monitoring, agricultural planting surveys, and geological exploration, soil sampling is a fundamental and crucial operational step. The effectiveness of the sampler directly determines the integrity of the soil sample and the accuracy of the test data.

[0003] However, after the soil sampler completes soil sampling, the soil sample tends to adhere tightly to the inner wall of the sampling component. Manual demolding is not only cumbersome and time-consuming, significantly reducing the overall efficiency of soil sampling, but also makes it difficult to control the force applied during manual peeling, which can easily cause soil sample defects and delamination, resulting in compromised sample integrity and affecting the accuracy of subsequent detection of soil nutrients, pollutants, and other indicators. Furthermore, the residual soil left on the inner wall of the sampling component during peeling not only wastes soil samples but also interferes with subsequent sampling operations, leading to sample mixing and data deviation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a soil sampler that facilitates the scraping of soil adhering to the inner wall of the sampling component, reduces soil buildup on the inner wall of the sampling component, and simplifies the steps for removing soil from the sampling component, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a soil sampler, including a vertical rod, with several sampling components detachably installed from top to bottom below the vertical rod. A connecting component is threaded between two adjacent sampling components. A lower threaded sleeve is threaded to the lower end of the bottom sampling component. Several insert plates are evenly distributed at the lower end of the lower threaded sleeve. A scraper is movably connected inside each sampling component. Threaded rods are fixedly installed at the upper and lower ends of the outer side of the scraper. A push plate located outside the sampling component is movably installed after the threaded rod passes through the interior of the sampling component. Fasteners are threaded to the inner wall of the push plate, and the inner wall of the fasteners is threaded to the outer wall of the threaded rod.

[0006] Preferably, horizontal bars are fixedly installed on the left and right sides of the upper end of the vertical rod, and a foot pedal is fixedly connected to the lower end of the vertical rod. An upper threaded sleeve is fixedly installed on the end of the foot pedal away from the vertical rod, and the lower end of the upper threaded sleeve is threadedly connected to the upper end of the sampling component at the top.

[0007] Preferably, the sampling component includes a first arc-shaped plate, a magnetic block, and a second arc-shaped plate. Magnetic blocks are fixedly installed on the front and rear sides of the first arc-shaped plate, and the first arc-shaped plate is magnetically connected to the second arc-shaped plate through the magnetic blocks.

[0008] Preferably, a viewing window is fixedly installed on both the first arc plate and the second arc plate, and through holes are opened on both the first arc plate and the second arc plate, located above and below the viewing window, and the inside of the through holes is movably connected to the threaded rod.

[0009] Preferably, the connecting assembly includes a partition, an upper end plate, and a lower end plate. The upper end of the partition is fixedly connected to the lower end of the upper end plate, and the lower end of the partition is fixedly connected to the upper end of the lower end plate. The inner walls of both the upper and lower end plates are threadedly connected to the sampling assembly.

[0010] Preferably, the lower threaded sleeve includes an annular block and an assembly ring. The lower end of the annular block is fixedly connected to the upper end of the insert plate, the upper end of the annular block is fixedly connected to the lower end of the assembly ring, and the inner wall of the assembly ring is threadedly connected to the lower end of the bottom sampling component.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model utilizes a sampling component, a scraper, and a push plate in cooperation. Fasteners and threaded rods enable the push plate and scraper to move smoothly within the sampling component. The scraper reciprocates between the sampling component and the soil, effectively removing soil adhering to the inner wall of the sampling component and successfully completing the soil sample removal process. This structure is easy to operate, has stable transmission, significantly reduces the probability of soil sample residue, avoids soil adhesion affecting sampling efficiency and sample integrity, improves the convenience and practicality of soil sampling operations, and is suitable for soil sampling work in various scenarios.

[0013] 2. This utility model achieves quick assembly and disassembly of the scraper by adjusting the connection state of the threaded rod and the fastener. When the fastener is separated from the threaded rod, the scraper can be removed from the push plate; when the two are locked together, the scraper can be securely assembled on the push plate. This assembly and disassembly structure is simple, reliable, and easy to operate. For scrapers that have been worn or damaged after long-term use, it is possible to quickly replace and maintain them without disassembling the entire equipment. This effectively reduces the difficulty of maintenance and operating costs, extends the overall service life of the equipment, and ensures the continuous and stable operation of sampling.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 2 , Figure 3 and Figure 8 A soil sampler includes a vertical rod 1, with horizontal bars 10 fixedly installed on the left and right sides of the upper end of the vertical rod 1, which facilitates the operator's hand gripping and pressing of the device, improving operational convenience. A foot pedal 11 is fixedly connected to the lower end of the vertical rod 1, allowing the operator to press the device into the soil by stepping on the foot pedal 11, reducing the difficulty of pressing. An upper threaded sleeve 12 is fixedly installed at the end of the foot pedal 11 away from the vertical rod 1, and the lower end of the upper threaded sleeve 12 is threadedly connected to the upper end of the sampling component 2 at the top, realizing the detachable assembly and disassembly of the sampling component 2 and the upper gripping structure, which facilitates the disassembly, storage and maintenance of the device.

[0026] Several sampling components 2 are detachably installed from top to bottom below the vertical rod 1. A connecting component 3 is threaded between adjacent sampling components 2. The number of sampling components 2 can be flexibly increased or decreased according to the actual sampling depth requirements to adapt to sampling operations in different soil layers. The connecting component 3 includes a partition plate 301, an upper end plate 302, and a lower end plate 303. The upper end of the partition plate 301 is fixedly connected to the lower end of the upper end plate 302, and the lower end of the partition plate 301 is fixedly connected to the upper end of the lower end plate 303. The inner walls of both the upper end plate 302 and the lower end plate 303 are threadedly connected to the sampling components 2. This double-layer threaded connection structure ensures the sealing and stability of the connection between adjacent sampling components 2.

[0027] Please see Figure 4 , Figure 7 and Figure 9 The bottom sampling component 2 has a threaded connection at its lower end to a threaded sleeve 4. The threaded sleeve 4 includes an annular block 401 and an assembly ring 402. The lower end of the annular block 401 is fixedly connected to the upper end of the insertion plate 5, and the upper end of the annular block 401 is fixedly connected to the lower end of the assembly ring 402. The inner wall of the assembly ring 402 is threadedly connected to the lower end of the bottom sampling component 2, making assembly and disassembly convenient and the connection stable. Several insertion plates 5 are evenly distributed at the lower end of the threaded sleeve 4. The insertion plates 5 have a conical structure, which can quickly penetrate into the soil, reduce the resistance of the equipment entering the soil, and improve sampling efficiency.

[0028] Each sampling component 2 has a scraper 6 movably connected inside. Threaded rods 7 are fixedly installed at the upper and lower ends of the scraper 6. The threaded rods 7 penetrate the interior of the sampling component 2 and are movably mounted on a push plate 8 located outside the sampling component 2. Fasteners 9 are threadedly connected to the inner wall of the push plate 8, and the inner wall of the fasteners 9 is threadedly connected to the outer wall of the threaded rods 7. Tightening the fasteners 9 locks the push plate 8 and the threaded rods 7 in place. Pressing the push plate 8 causes the threaded rods 7 and scraper 6 to move smoothly back and forth inside the sampling component 2. The scraper 6 thoroughly scrapes away the soil adhering to the inner wall of the sampling component 2, completing the soil sample removal operation. When the fasteners 9 are separated from the threaded rods 7, the scraper 6 can be directly removed from the push plate 8, facilitating the individual replacement of worn or damaged scrapers 6 without disassembling the entire device, making maintenance convenient.

[0029] Please see Figure 6 , Figure 5 and Figure 1The sampling component 2 includes a first arc-shaped plate 201, a magnetic block 202, and a second arc-shaped plate 203. Magnetic blocks 202 are fixedly installed on the front and rear sides of the first arc-shaped plate 201, and the first arc-shaped plate 201 is magnetically connected to the second arc-shaped plate 203 via the magnetic blocks 202. This magnetic opening and closing structure facilitates quick opening of the sampling component 2 after sampling to remove the complete soil sample. A viewing window 13 is fixedly installed on both the first arc-shaped plate 201 and the second arc-shaped plate 203, allowing operators to directly observe the internal soil sampling volume and sampling status, facilitating timely control of the sampling progress. Simultaneously, through holes 14 are provided on both the first arc-shaped plate 201 and the second arc-shaped plate 203, located above and below the viewing window 13. The interior of the through holes 14 is movably sleeved with the threaded rod 7, providing a limiting and guiding function for the threaded rod 7, ensuring smooth and non-deviation-free movement of the scraper 6, and guaranteeing the scraping effect.

[0030] Working principle: During use, the operator assembles the corresponding number of sampling components 2 according to the required sampling depth, and completes the splicing and fixing through the connecting components 3. The bottom insert plate 5 is aligned with the sampling point, and the operator holds the crossbar 10 and uses the foot pedal 11 to press the device into the soil to complete the sampling. After sampling, the device is pulled out, and the push plate 8 is pushed to drive the scraper 6 to slide along the inner wall of the sampling component 2 to scrape off the soil adhering to the inner wall and complete the material removal. After long-term use, the fasteners 9 can be loosened, and the worn scraper 6 can be disassembled and replaced separately. The device is easy to assemble and disassemble, operates stably, and effectively improves the sample integrity and work efficiency of soil sampling.
