Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil testing technology, specifically a soil testing sampling device. Background Technology
[0002] In the field of soil testing, obtaining representative soil samples is a key prerequisite for accurate analysis and research. Traditional soil sampling methods and devices have many limitations, especially in environments such as the field where there is no power supply. Although some electric sampling devices can perform sampling operations efficiently, their reliance on power makes them difficult to operate in remote areas such as wilderness, and they cannot meet the sampling needs under conditions without power access.
[0003] In addition, some existing manual sampling tools still need improvement in terms of ease of operation, sampling depth, and ease of sample retrieval after sampling. For example, some manual sampling devices have difficulty effectively penetrating relatively hard soil layers, and after sampling, soil samples are easily stuck in the sampling tube, making it difficult to remove them completely and conveniently. This not only increases the labor intensity of operators, but may also affect the integrity of the samples and the accuracy of the test results.
[0004] To address these issues, this invention provides a soil sampling device for testing. Utility Model Content

The sampling assembly includes a first screw threaded through the interior of the main block, and a connecting rod fixedly installed at the bottom of the first screw. The removal assembly includes a second screw, a push plate fixedly installed at the bottom of the second screw, and a sampling cylinder sleeved between the push plate and the outer side of the second screw.

[0012] Beneficial effects
[0013] This invention provides a soil sampling device. Compared with the prior art, it has the following advantages:
[0014] 1. This soil sampling device utilizes the cooperation of a first screw and a second screw to perform soil sampling without the use of electricity. The downward rotation of the first screw is a deceleration motion that can provide a large torque for breaking the soil, ensuring that soil sampling can be effectively carried out in areas without power supply, such as wilderness areas. This greatly improves the applicability and flexibility of the device and reduces dependence on external energy.

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.
[0023] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] Reference Figures 1 to 4 This application provides a soil sampling device, including a main block 1, a support component 2 at the bottom of the main block 1, a sampling component 3 inside the main block 1, and a removal component 4 inside the sampling component 3. The sampling component 3 includes a first screw 33, which is screwed through the interior of the main block 1. A connecting rod 32 is fixedly installed at the bottom of the first screw 33. The removal component 4 includes a second screw 45, a push plate 46 is fixedly installed at the bottom of the second screw 45, and a sampling cylinder 31 is sleeved between the push plate 46 and the outer side of the second screw 45. A turntable 34 is fixedly installed at the top of the first screw 33, and a first lever 35 is fixedly installed on the outer side of the turntable 34.
[0025] The support assembly 2 includes a support rod 21, which is fixedly installed on the outside of the main body block 1. A support ring 22 is fixedly installed between the bottoms of the support rod 21. A connecting block 23 is fixedly installed on the outside of the support ring 22. A plug rod 24 is fixedly installed at the bottom of the connecting block 23.
[0026] In this embodiment, when sampling the soil, the support ring 22 is fixed to a certain extent by inserting the insertion rod 24 into the soil. After fixing, the main block 1 is supported by the support rod 21. The turntable 34 is rotated by the first lever 35, and the first screw 33 is rotated by the rotation of the turntable 34. The first screw 33 can move up and down along the main block 1 while rotating. The up and down movement of the first screw 33 drives the sampling cylinder 31 to rotate and move upward through the connecting rod 32 and the second screw 45. The sampling cylinder 31 can be screwed into the soil while moving downward, thereby realizing soil sampling. Moreover, the downward rotation of the first screw 33 is a deceleration motion, which can provide a large torque to break the soil, thus ensuring that soil sampling can be effectively carried out when no electricity is used, ensuring convenience when sampling in the wilderness.
[0027] Reference Figures 1 to 4 In one aspect of this embodiment, a connecting cylinder 42 is fixedly mounted on the top of the sampling cylinder 31. The connecting cylinder 42 is sleeved on the outside of the second screw 45. A connecting ring 41 is fixedly mounted on the top of the connecting cylinder 42 and sleeved on the outside of the second screw 45. A rotating cylinder 43 is rotatably connected to the top of the connecting ring 41. A second lever 44 is fixedly mounted on the outside of the rotating cylinder 43, and the rotating cylinder 43 is screwed onto the outside of the second screw 45. The thread direction of the second screw 45 is opposite to that of the thread direction of the first screw 33.
[0028] In this embodiment, after sampling is completed, the rotating cylinder 43 is driven to rotate by the second lever 44. While rotating, the rotating cylinder 43 moves along the second screw 45. The movement of the second screw 45 can drive the connecting cylinder 42 and the connecting ring 41 to move. The upward movement of the connecting ring 41 can drive the sampling cylinder 31 to move upward synchronously. The upward movement of the sampling cylinder 31 causes the push plate 46 to move downward relative to the sampling cylinder 31. The downward movement of the push plate 46 can push out the sample located inside the sampling cylinder 31, thereby achieving the purpose of conveniently removing the sampled soil. Furthermore, the reverse thread arrangement of the first screw 33 and the second screw 45 ensures that the sampling cylinder 31 will not move upward under the reverse action of friction when it is screwed in.
[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0030] Working principle: When sampling soil, the insertion rod 24 is inserted into the soil to fix the support ring 22 to a certain extent. After fixing, the support rod 21 supports the main block 1. The first lever 35 drives the turntable 34 to rotate, which in turn drives the first screw 33 to rotate. While rotating, the first screw 33 can move up and down along the main block 1. The up and down movement of the first screw 33 drives the sampling cylinder 31 to rotate and move upward through the connecting rod 32 and the second screw 45. The downward movement of the sampling cylinder 31 and its rotation can screw the sampling cylinder 31 into the soil, thereby realizing soil sampling. The downward rotation of the first screw 33 is a decelerating motion, which can provide a large torque for breaking the soil, thus ensuring that the sampling cylinder can be inserted into the soil without the use of electricity. This system effectively allows for soil sampling, ensuring convenience during field sampling. After sampling, the second lever 44 drives the rotating cylinder 43 to rotate. As the rotating cylinder 43 rotates, it moves along the second screw 45. The movement of the second screw 45 drives the connecting cylinder 42 and the connecting ring 41 to move. The upward movement of the connecting ring 41 drives the sampling cylinder 31 to move upward synchronously. The upward movement of the sampling cylinder 31 causes the push plate 46 to move downward relative to the sampling cylinder 31. The downward movement of the push plate 46 pushes out the sample inside the sampling cylinder 31, thus achieving the purpose of convenient soil removal after sampling. Furthermore, the opposing threads of the first screw 33 and the second screw 45 ensure that the sampling cylinder 31 will not move upward under the reverse action of friction when it is screwed in.
