[0003] The sampling device used for soil testing is inconvenient to disassemble and replace the sampling tube when sampling soil at different depths, making it inconvenient to use. Utility Model Content
[0004] The purpose of this invention is to provide a sampling device for soil testing, which solves the problem that it is inconvenient to disassemble and replace the sampling tube when sampling soil at different depths, making it inconvenient to use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for soil testing, comprising a sampling cylinder, a fixing block fixedly connected to the upper end of the sampling cylinder, a threaded rod contacting the upper end of the fixing block, a handrail fixedly connected to the upper end of the threaded rod, a limiting sleeve rotatably connected to the outer side of the fixing block, a positioning plate fixedly connected to the outer side of the threaded rod, the positioning plate contacting the limiting sleeve, a positioning rod fixedly connected to the lower end of the positioning plate, a pressure plate fixedly connected to the upper end of the sampling cylinder, the positioning rod slidably connected to the pressure plate, and a material taking mechanism provided on the sampling cylinder.
[0006] Preferably, the limiting sleeve contacts the sampling cylinder, and the limiting sleeve is connected to the threaded rod by a thread. The design of the limiting sleeve allows for easy disassembly and replacement of the sampling cylinder.
[0007] Preferably, a protrusion is fixedly connected to the outer side of the fixing block, and the protrusion is slidably connected to the limiting sleeve. Through the design of the protrusion, the limiting sleeve can be limited.
[0008] Preferably, the sampling mechanism includes a push plate, which is slidably connected inside the sampling cylinder. A slider is fixedly connected to the outside of the push plate and slidably connected to the sampling cylinder. A connecting block is fixedly connected to the outside of the slider away from the push plate. A support plate is fixedly connected to the outside of the sampling cylinder. A sliding rod is slidably connected inside the support plate and a spring is provided on the outside of the sliding rod. By pressing down on the sliding rod, the sliding rod compresses the spring and slides within the support plate, causing the sliding rod to move the connecting block, which in turn moves the slider, which in turn moves the push plate. This allows the push plate to slide within the sampling cylinder and push out the sample soil from the sampling cylinder, facilitating material collection from the sampling cylinder.
[0009] Preferably, the connecting block is in contact with the sampling cylinder and is fixedly connected to the slide rod. The design of the connecting block can drive the push plate to move.
[0010] Preferably, one end of the spring contacts the support plate, and the other end of the spring contacts the slide rod. Through the design of the spring, the push plate can be driven to reset.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model, by setting up components such as a limiting sleeve, a positioning plate, and a positioning rod, allows the sampling cylinder to be removed and replaced by rotating the limiting sleeve to cause threaded movement between the limiting sleeve and the threaded rod, thus making the threaded rod slide out of the limiting sleeve. This solves the problem that it is inconvenient to disassemble and replace the sampling cylinder when sampling soil at different depths in soil testing devices, making it inconvenient to use.
[0013] 2. This utility model, by setting up components such as a push plate, a connecting block, and a spring, allows the connecting block to move by moving a sliding rod. The connecting block then drives the push plate to slide inside the sampling cylinder via a slider, thus pushing out the soil sample from the sampling cylinder, making it convenient for material collection.

Through the design of the limiting sleeve 23, the sampling cylinder 1 can be easily disassembled and replaced.
[0021] Please see Figure 2-4 A protrusion 24 is fixedly connected to the outer side of the fixed block 2. The protrusion 24 is slidably connected to the limiting sleeve 23. The protrusion 24 can limit the limiting sleeve 23. A positioning plate 25 is fixedly connected to the outer side of the threaded rod 21. The positioning plate 25 contacts the limiting sleeve 23. A positioning rod 26 is fixedly connected to the lower end of the positioning plate 25. A pressure plate 27 is fixedly connected to the upper end of the sampling cylinder 1. The positioning rod 26 is slidably connected to the pressure plate 27. A material taking mechanism 3 is provided on the sampling cylinder 1.
[0022] Please see Figure 2-4The sampling mechanism 3 includes a push plate 31, which is slidably connected inside the sampling cylinder 1. A slider 32 is fixedly connected to the outside of the push plate 31 and is slidably connected to the sampling cylinder 1. A connecting block 33 is fixedly connected to the outside of the slider 32 away from the push plate 31. A support plate 34 is fixedly connected to the outside of the sampling cylinder 1, and a sliding rod 35 is slidably connected inside the support plate 34. The connecting block 33 contacts the sampling cylinder 1 and is fixedly connected to the sliding rod 35. The design of the connecting block 33 allows the push plate 31 to move. A spring 3 is provided on the outside of the sliding rod 35. 6. One end of the spring 36 contacts the support plate 34, and the other end of the spring 36 contacts the slide rod 35. Through the design of the spring 36, the push plate 31 can be reset. By pressing down the slide rod 35, the slide rod 35 squeezes the spring 36 and slides the slide rod 35 in the support plate 34, causing the slide rod 35 to drive the connecting block 33 to move, causing the connecting block 33 to drive the slider 32 to move, causing the slider 32 to drive the push plate 31 to move, so that the push plate 31 can slide in the sampling cylinder 1, and push the sample soil in the sampling cylinder 1 can be pushed out, which can facilitate the sampling of materials in the sampling cylinder 1.
[0023] The specific implementation process of this utility model is as follows: In use, by pressing down the sliding rod 35, the sliding rod 35 compresses the spring 36 and causes the sliding rod 35 to slide within the support plate 34, causing the sliding rod 35 to drive the connecting block 33 to move, causing the connecting block 33 to drive the slider 32 to move, causing the slider 32 to drive the push plate 31 to move, so that the push plate 31 can slide within the sampling cylinder 1, causing the push plate 31 to push out the sample soil within the sampling cylinder 1, which facilitates the sampling of material from the sampling cylinder 1;
[0024] By rotating the limiting sleeve 23, the limiting sleeve 23 and the threaded rod 21 undergo threaded movement, causing the threaded rod 21 to slide inside the limiting sleeve 23 and slide out of the limiting sleeve 23. The threaded rod 21 also drives the positioning plate 25 to move, which in turn drives the positioning rod 26 to move, causing the positioning rod 26 to slide out of the pressure plate 27. This allows the sampling cylinder 1 to be removed for easy replacement.
