Description

Technical Field

[0001] This application relates to the field of soil sampling technology in civil engineering, geological exploration and environmental monitoring, and in particular to a soil testing device that is easy to use for sampling. Background Technology

[0002] Currently, soil sampling is a crucial foundational task in fields such as civil engineering, geological exploration, and environmental monitoring. Existing soil sampling tools mainly include manual drills, electric drills, and hydraulically driven drilling systems. While these tools meet the needs of different scenarios to some extent, they still present some problems in practical operation, such as inconvenience in operation, low efficiency, and easy damage to samples. With the advancement of technology and social development, the demand for high-precision and high-efficiency soil sampling is increasing, which places higher demands on existing sampling tools.

[0003] Existing sampling devices generally suffer from problems such as cumbersome operation, long time consumption, high physical and technical requirements for operators, and difficulty in ensuring sample integrity. Especially under complex terrain conditions, traditional sampling tools often cannot effectively cope with diverse soil types and site environments, limiting the accuracy and reliability of sampling. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a soil testing device that is easy to operate and overcomes the shortcomings of the prior art. It aims to solve the problems that existing sampling devices in the prior art are generally cumbersome to operate, time-consuming, require high physical strength and technical skills from the operator, and have difficulty in ensuring sample integrity. Especially under complex terrain conditions, traditional sampling tools often cannot effectively cope with diverse soil types and site environments, which limits the accuracy and reliability of sampling.

[0005] To achieve the above objectives, this application provides the following technical solution: a soil testing device for easy sampling operation, comprising a main rod, a push rod slidably connected inside the main rod, a sampling cylinder at the bottom of the main rod, a piston fixedly installed through the bottom of the push rod through the bottom of the sampling cylinder, the piston slidably connected inside the sampling cylinder, a cutting edge at the bottom of the sampling cylinder, multiple sets of locking ports and slots respectively opened on the outside of the main rod, a locking mechanism at the top of the push rod, the locking mechanism including a handle, a fixed block on one side of the handle, a moving slot at the bottom of the handle, a moving block slidably connected inside the moving slot, the handle slidably connected inside the slot, a connecting rod on one side of the moving block, a hinge block hinged to one side of the fixed block, one end of the connecting rod passing through the fixed block and hinged to one side of the hinge block, a locking block on the front of the hinge block, multiple sets of springs between the hinge block and the fixed block, and the locking block matching the locking port.

[0006] By adopting the above technical solution and setting a main rod, when soil samples need to be collected, the sampling tube is first inserted directly into the target location through the cutting edge at the bottom of the sampling tube. At the same time, the sliding block at the bottom of the handle unlocks the push rod and pushes it downward. The push rod drives the piston inside the sampling tube downward, creating negative pressure, which then sucks the soil into the sampling tube. After sampling is completed, the sliding block is released, and the hinge block will automatically reset under the action of the spring to prevent sample leakage. Then, the push rod is operated in reverse to remove the required soil sample from inside the sampling tube. This setting simplifies the sampling operation process, improves sampling efficiency, ensures the integrity and accuracy of the sample, avoids sample contamination and damage that may be caused by traditional tools, adapts to various soil types and complex terrain conditions, and enhances the versatility and applicability of the equipment.

[0012] By adopting the above technical solution and setting a slide rail, the stability of the push rod sliding up and down inside the main rod can be further improved during use, preventing deviation and enhancing the practicality of the device.

[0013] As a preferred technical solution of this application, the top of the main rod is provided with a top cover, and the bottom of the top cover is provided with two sets of reinforcing rods, the bottom of the two sets of reinforcing rods being fixedly connected to the top of the connecting block.

[0014] By adopting the above technical solution and setting a top cover, the push rod can be limited to prevent it from falling off. At the same time, the reinforcing rod can improve the overall structural strength of the device and reduce the possibility of damage.

[0015] As a preferred technical solution of this application, a scale is provided on one side of the main rod, and the surface of the scale is coated with a fluorescent agent.

[0020] By adopting the above technical solutions, the main rod and sampling cylinder are made of high-strength stainless steel and corrosion-resistant aluminum alloy, respectively, which can further improve the structural strength of the device body and extend its service life. The push rod is made of high-quality carbon steel and the surface is chrome-plated to further improve its wear resistance.

[0021] The beneficial effects of this application are:

[0022] 1. By setting the main rod, when soil samples need to be collected, the sampling tube is first inserted directly into the target location through the cutting edge at the bottom of the sampling tube.

The bottom of the handle 401 has a movable groove 403, and a movable block 404 is slidably connected inside the movable groove 403. The handle 401 is slidably connected inside the empty groove 106. A connecting rod 405 is provided on one side of the movable block 404, and a hinge block 406 is hinged to one side of the fixed block 402. One end of the connecting rod 405 passes through the fixed block 402 and is hinged to one side of the hinge block 406. A locking block 407 is provided on the front of the hinge block 406. Multiple sets of springs 408 are provided between the hinge block 406 and the fixed block 402. The locking block 407 matches the locking port 103. The sampling cylinder 2 has multiple sets of stabilizing circular rails 202 inside, and multiple sets of stabilizing grooves 302 are provided on the outer side of the piston 301. The stabilizing grooves 302 are slidably connected to the stabilizing circular rails 202.

[0032] By setting the main rod 1, when soil samples need to be collected, the sampling tube 2 is first inserted directly into the target position through the cutting edge 201 at the bottom of the sampling tube 2. At the same time, the sliding block 404 at the bottom of the handle 401 is slid to unlock the push rod 3 and push it downward. The push rod 3 drives the piston 301 inside the sampling tube downward, forming a negative pressure, which can then suck the soil into the sampling tube 2. After sampling is completed, the moving block 404 is released, and the hinge block 406 will automatically reset under the action of the spring 408 to prevent sample leakage. Then, the push rod 3 is operated in reverse to take out the required soil sample from inside the sampling tube 2. This setting simplifies the sampling operation process, improves sampling efficiency, ensures the integrity and accuracy of the sample, avoids sample contamination and damage that may be caused by traditional tools, adapts to various soil types and complex terrain conditions, and enhances the versatility and applicability of the equipment. By setting a stable circular rail 202, the stability of the piston 301 during vertical movement can be further improved, and the contact area between the soil sample and the inner wall of the sampling cylinder 2 can be further increased, reducing the occurrence of sample falling.

[0033] Reference Figure 1 The main rod 1 has a connecting block 101 at its bottom, with a connecting port 102 at its bottom. The sampling cylinder 2 has a threaded interface 203 at its top, which is threadedly connected to the connecting port 102. The cutting edge 201 is threadedly connected to the bottom of the sampling cylinder 2. The main rod 1 has two sets of slide rails 104 inside, and the push rod 3 has grooves 303 on both sides, which match the slide rails 104. A scale 105 is provided on one side of the main rod 1, and the surface of the scale 105 is coated with fluorescent agent. By setting up a connecting block 101, the main rod 1 can be connected to the sampling cylinder 2. The threaded connection between the connecting block 101 and the threaded interface 203 allows for quick replacement of the sampling cylinder 2 during use, providing greater flexibility in different terrains and sampling situations and enhancing the device's practicality. The slide rail 104 further improves the stability of the push rod 3 sliding up and down inside the main rod 1, preventing deviation and further enhancing the device's usability. The scale 105 allows staff to accurately monitor the sampling depth during use.

[0034] Reference Figure 1The main rod 1 is topped with a top cover 5, and the bottom of the top cover 5 is fitted with two sets of reinforcing rods 501. The bottom of the two sets of reinforcing rods 501 is fixedly connected to the top of the connecting block 101. By setting the top cover 5, the push rod 3 can be limited to prevent it from falling off. At the same time, the reinforcing rods 501 can improve the overall structural strength of the device and reduce the possibility of damage. The handle 401 is fitted with an anti-slip sleeve, and the bottom of the moving block 404 is fitted with an anti-slip plate 409. By setting the anti-slip sleeve and the anti-slip plate 409, it is easier and more stable for the operator to use the device, further improving its practicality. The main rod 1 is made of high-strength stainless steel, the sampling cylinder 2 is made of corrosion-resistant aluminum alloy, and the push rod 3 is made of high-quality carbon steel with a chrome-plated surface. The main rod 1 and the sampling cylinder 2 are made of high-strength stainless steel and corrosion-resistant aluminum alloy, respectively, which can further improve the structural strength of the device body and extend its service life. The push rod 3 is made of high-quality carbon steel with a chrome-plated surface, which can further improve its wear resistance.

[0035] Working principle: By setting the main rod 1, when it is necessary to collect soil samples, the sampling tube 2 is first inserted directly into the target position through the cutting edge 201 at the bottom of the sampling tube 2. At the same time, the sliding block 404 at the bottom of the sliding handle 401 unlocks the push rod 3 and pushes it downward. The push rod 3 drives the piston 301 inside the sampling tube downward, creating negative pressure, which can then suck the soil into the sampling tube 2. After sampling is completed, the sliding block 404 is released, and the hinge block 406 will automatically reset under the action of the spring 408 to prevent sample leakage. Then, the push rod 3 is operated in reverse. The required soil sample is extracted from the inside of the sampling tube 2. This design simplifies the sampling process, improves sampling efficiency, ensures the integrity and accuracy of the sample, avoids sample contamination and damage that may be caused by traditional tools, adapts to various soil types and complex terrain conditions, and enhances the versatility and applicability of the equipment. By setting the threaded connection between the connecting block 101 and the threaded interface 203, the sampling tube 2 can be quickly replaced during use. It is more flexible in the face of different terrains and different sampling situations, and improves the practicality of the device.

[0036] Among them, by setting a stable circular rail 202, the stability of the piston 301 when moving up and down can be further improved during use. At the same time, the contact area between the soil sample and the inner wall of the sampling tube 2 can be further strengthened, reducing the occurrence of sample falling. By setting a slide rail 104, the stability of the push rod 3 sliding up and down inside the main rod 1 can be further improved during use, preventing the phenomenon of deviation and improving the practicality of the device.

[0037] Meanwhile, by setting the top cover 5, the push rod 3 can be limited to prevent it from falling off. At the same time, the reinforcing rod 501 can improve the overall structural strength of the device and reduce the possibility of damage.

[0038] In addition, by setting a scale 105, staff can easily monitor the sampling depth during use; by setting an anti-slip sleeve and anti-slip plate 409, staff can use the device more conveniently and stably, further improving its practicality; the main rod 1 and sampling cylinder 2 are made of high-strength stainless steel and corrosion-resistant aluminum alloy respectively, which can further improve the structural strength of the device body and extend its service life; the push rod 3 is made of high-quality carbon steel with chrome plating, which can further improve its wear resistance.
