Description

Technical Field

[0001] This utility model relates to the field of forestry ecological monitoring equipment technology, and in particular to a soil sampler for forestry ecological monitoring. Background Technology

[0002] Forestry soil samplers have wide applications in forestry soil research, environmental monitoring, forest ecological restoration, and geological disaster prediction. By collecting and analyzing soil samples, researchers can gain a deeper understanding of the physical, chemical, and biological properties of the soil, thereby providing a scientific basis for forestry production and management.

[0003] Currently, the common sampling method involves inserting a sharpened cylindrical sampler into the sampling area and then pulling it out to collect a soil sample. However, there is a problem with the existing method: when the cylindrical sampler is directly pulled out after being inserted into the soil, the soil inside is prone to detachment because the bottom of the soil is still connected to the ground, making it difficult to remove the sample completely.

[0004] To address this issue, it is recommended to optimize the design of the sampler. It is necessary to propose a soil sampler for forestry ecological monitoring, optimize the use of the sampler, reduce the impact on the integrity of the soil sample, and thus improve the sampling success rate.

The top of the sampling tube is slidably fitted with a pusher for ejecting soil samples. A pressure rod is detachably threaded to the top of the pusher. The sampling tube is also equipped with a mounting base, with mounting shafts on both sides. A rotating frame is rotatably mounted between the two mounting shafts. A cutting blade for cutting the bottom of the sampled soil is located at the end of the rotating frame. When the rotating frame is rotated, the cutting blade can fit against the bottom of the sampling tube to cut the bottom of the soil sample.

[0007] To further explain, it also includes guide sleeves, locking rods, and elastic elements. Guide sleeves are symmetrically arranged at the top of the sampling cylinder. Locking rods that are adapted to engage with the jacking member are slidably inserted through the guide sleeves to limit the position of the jacking member. Elastic elements are arranged between the locking rods and the guide sleeves on the same side.

[0008] To further explain, it also includes a protective shell, which is fitted onto the rotating frame to cover the slitting blade. The bottom of the protective shell has an opening to expose the blade portion of the slitting blade.

[0009] Further, the magnet is arranged on both sides of the protective shell and magnetically attracts the rotating frame to stabilize the position of the protective shell.

[0010] Further, the positioning nail is arranged on the end of the mounting shaft to assist the insertion of the sampling cylinder.

[0011] Further, the through hole is arranged at the top end of the sampling cylinder.

[0012] The utility model discloses the beneficial effect is: 1, the utility model discloses the rotary cutting function of the splitting knife, effectively cut the connection of the bottom of soil and ground, avoid soil sample to fall off when taking out, and the cooperation design of the top drive part and the down pressure rod makes soil sample can be quickly, stably and top out, and operation is simple, and the sampling efficiency is improved significantly, and the integrity and representativeness of sample are ensured.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0022] Example: A soil sampler for forestry ecological monitoring, such as Figures 1-3 As shown, the system includes a sampling cylinder 1, a top actuator 2, a pressure rod 3, a mounting base 4, a mounting shaft 5, a rotating frame 6, and a cutting blade 61. The sampling cylinder 1 is a hollow cylinder with a closed top, used to hold soil samples for monitoring. The top of the sampling cylinder 1 is slidably fitted with a top actuator 2 for ejecting the soil sample. The top actuator 2 slides vertically. Specifically, the top actuator 2 consists of an upwardly extending rod and a top plate connected to the bottom of the rod and placed inside the sampling cylinder 1. The top plate is adapted to the inner diameter of the sampling cylinder 1 and can tightly fit against the inner wall of the sampling cylinder 1 to eject the soil inside. A pressure rod 3 is detachably threaded to the top of the top actuator 2. The setting of the pressure rod 3 makes the pushing operation of the top actuator 2 more efficient. The sampling tube 1 is designed for easy handling, allowing the operator to grip and push the top actuator 2 downwards to eject the soil sample. Simultaneously, through holes 11 are spaced circumferentially at the top of the sampling tube 1 to help expel air during sample ejection, reducing soil sample compression and deformation and ensuring sample integrity. A mounting base 4 is fixedly installed at the upper end of the sampling tube 1. Mounting shafts 5 are located on both sides of the mounting base 4, and a rotating frame 6 is rotatably mounted between the two mounting shafts 5. The rotating frame 6 can rotate 360 ​​degrees circumferentially, and a cutting blade 61 is located at the end of the rotating frame 6 to cut the bottom of the sampled soil. When the rotating frame 6 is rotated, the cutting blade 61 can cut against the bottom of the sampling tube 1, effectively severing the connection between the bottom of the soil and the ground.

[0023] Therefore, through the coordinated operation of the aforementioned components, the rotating frame 6 first drives the cutting blade 61 to rotate, cutting the bottom of the soil sample from the ground by fitting it against the bottom of the sampling cylinder 1. This ensures complete separation of the soil sample from the ground, preventing the sample from falling out during extraction and significantly improving the integrity and representativeness of the sampling. Subsequently, by pushing the downward pressure rod 3, the jacking component 2 is driven to push the soil sample out of the sampling cylinder 1, making the operation more convenient and efficient. This design makes the sampling process in forestry ecological monitoring smoother and more precise, greatly improving the efficiency and reliability of sampling.

[0024] like Figure 4As shown, it also includes a guide sleeve 8, a clamping rod 9 and an elastic member 10, the sampling cylinder 1 is symmetrically provided with a guide sleeve 8 at the top, and the guide sleeve 8 is slidably provided with a clamping rod 9 matched with the ejector 2, thereby effectively limiting the position of the ejector 2 in the non-working state, and the clamping rod 9 and the guide sleeve 8 on the same side are provided with an elastic member 10, which is a spring in this embodiment. This structure design effectively prevents the accidental movement of the ejector 2 in the non-working state, reduces the risk of equipment failure, and improves the reliability of the overall device.

[0025] As shown in Figure 1 and Figure 3 It also includes a protective shell 7, which is sleeved on the rotating frame 6 to cover the slitting knife 61, and the protective shell 7 can completely cover the slitting knife 61 to provide safety protection, and the bottom of the protective shell 7 is provided with an opening for exposing the cutting edge of the slitting knife 61, ensuring that it can normally contact the soil for cutting operation when working. By setting the protective shell 7, the operator can effectively avoid accidental contact with the sharp part of the slitting knife 61 during use, thereby greatly improving the safety of the equipment, especially suitable for field operation environment.

[0026] As shown in Figure 1 It also includes a magnet 13, and the two sides of the protective shell 7 are provided with a magnet 13 magnetically attracted to the rotating frame 6. The introduction of the magnet 13 firmly fixes the protective shell 7 on the rotating frame 6 through magnetic attraction, effectively preventing it from deviating due to external vibration or improper operation, and ensuring the stability of the equipment operation.

[0027] As shown in Figure 3 It also includes a positioning nail 12, and the end of the mounting shaft 5 is provided with a positioning nail 12. The main function of the positioning nail 12 is to assist the sampling cylinder 1 in precise positioning when inserted into the soil, ensuring the stability and accuracy of the sampling process.

[0028] First, the sampling cylinder 1 is inserted into the soil area to be sampled, and the positioning pin 12 is inserted synchronously to assist the insertion and positioning of the sampling cylinder 1 until the soil sample is completely placed in the sampling cylinder 1. Then, the whole is taken out with a tool. Due to the connection and adhesion of the roots of the soil, some excess soil may accumulate at the bottom of the sample. At this time, by rotating the rotating frame 6, the slitting knife 61 is moved towards the bottom end of the sampling cylinder 1, and the rotating action of the slitting knife 61 cuts the bottom of the soil, ensuring that the soil sample is separated from the ground and preventing the sample from falling off when it is taken out, so that the soil is completely retained in the sampling cylinder 1. At the same time, the protective shell 7 shields the side of the slitting knife 61 facing the operator to ensure safety. Next, pull the clamping rod 9 to make it slide on the guide sleeve 8 and away from the ejector 2, and the elastic member 10 deforms accordingly, releasing the position restriction of the ejector 2. By pushing the ejector 2 downward through the push rod 3, the ejector 2 slides from the top to the bottom of the sampling cylinder 1. The through hole 11 at the top end of the sampling cylinder 1 is designed to help expel air during sampling, reducing the compression and deformation of the soil sample, thereby ejecting the cut soil sample from the sampling cylinder 1. Finally, the operator can take out the soil sample and perform subsequent analysis.

[0029] Through the above steps, the soil sampler can efficiently and completely collect soil samples, reduce damage to the soil structure, and ensure operation safety and sampling accuracy.

[0030] The above has introduced the present application in detail, and the principle and implementation mode of the present application have been described by applying specific examples. The above example is only used to help understand the method of the present application and its core idea; at the same time, for those skilled in the art, according to the idea of the present application, the specific implementation mode and application range will be changed; in view of the above, the content of the specification should not be understood as a limitation of the present application.
