Description

Technical Field

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

[0002] Environmental monitoring refers to the activities of environmental monitoring agencies in monitoring and measuring the status of environmental quality. Environmental monitoring determines the level of environmental pollution and quality by monitoring and measuring indicators that reflect environmental quality. The content of environmental monitoring mainly includes the monitoring of physical indicators, chemical indicators, and ecosystems. Soil samplers are tools used to obtain soil samples. Commonly used ones include soil augers, shovels, and spades.

[0003] In addition, electric or diesel engine sampling devices are also used for sampling. However, these devices are expensive and not suitable for simple environmental monitoring sampling. Therefore, most environmental monitoring sampling is still done manually. Manual samplers have a simple structure, including a sampling tube, a vertical rod, and a handle. A foot pedal is installed on the top of the sampling tube. When in use, the sampling tube is stepped into the soil by stepping on the foot pedal, and then the sampling tube is pulled out.

[0004] However, the aforementioned devices have the following drawbacks: when sampling relatively moist soil, the soil is easily retained inside the sampling tube and removed; however, when sampling relatively dry and loose soil, the soil easily falls out of the tube when it is pulled out. Furthermore, some samplers without a foot pedal require force to press down the handle to insert the sampling tube into the soil layer, which is quite laborious; additionally, for some soil types, using a foot pedal is not very effective. Therefore, further improvements are needed. To this end, we propose a soil sampler for ecological environment monitoring. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a soil sampler for ecological environment monitoring.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a soil sampler for ecological environment monitoring, comprising a sampling tube, wherein the bottom end of the sampling tube is open and has an inwardly curved design; a detachable intermediate tube is fixed to the top end of the sampling tube; a sleeve is fitted onto the surface of the intermediate tube, and a side hole is provided on the side wall of the sleeve; an insertion component is provided inside the side hole; a positioning hole for inserting the insertion component is provided on the middle side wall of the intermediate tube; a movable rod is slidably connected inside the intermediate tube, and a handle is fixed to the top end of the movable rod; an impact rod is fixed to the bottom end of the movable rod; and a compaction component is provided at the top end of the sampling tube and the bottom end of the intermediate tube.

[0007] Furthermore, the top of the sampling tube is connected and fixed with an external threaded connecting tube, the bottom of the intermediate tube has an internal thread, and the bottom of the intermediate tube is rotatably connected to the surface of the external threaded connecting tube through the thread.

[0008] Furthermore, the insertion assembly includes a plug rod that passes through the inside of the side hole and is slidably connected to the side hole. An end cap is fixed to one end of the plug rod outside the sleeve. A tension spring is fixedly connected to the end cap and the outer wall of the sleeve. The end of the plug rod inside the sleeve can be inserted into the positioning hole.

[0009] Furthermore, a pull ring is fixedly connected to the surface of the end cap.

[0010] Furthermore, two symmetrical strip grooves are formed on the side wall of the intermediate tube, and the two ends of the impact rod are slidably connected to the two strip grooves.

[0011] Furthermore, two pedals are fixed on both sides of the bottom end of the intermediate tube, and the surface of the pedals is provided with anti-slip texture.

[0012] Furthermore, the compaction assembly includes a pressure plate located inside the sampling tube, and a stop bar is fixed in the middle of the upper surface of the pressure plate, with the top end of the stop bar extending into the interior of the intermediate tube.

[0013] The beneficial effects of this utility model are:

[0014] 1. In use, this utility model comprises a sampling tube, an intermediate tube, a sleeve, a movable rod, a handle, an impact rod, and a compaction component. First, the sleeve is fixed to the middle of the intermediate tube using the plug-in component. Then, the movable rod is slid up and down, and the impact rod strikes the sleeve, thereby driving the sampling tube into the soil layer. Next, the sleeve is released, allowing it to slide to the bottom of the intermediate tube. The movable rod is then slid up and down again, and the impact rod strikes the compaction component, thereby compacting the soil sample inside the sampling tube. Finally, the sampling tube is rotated and pulled out to remove the soil sample. This sampler has a simple structure, ensures that the soil does not fall out of the sampling tube when sampling soft soil, and uses an impact method to drive the sampling tube into the soil layer, making it more labor-saving and convenient to use.

[0015] 2. When using this utility model, the bottom end of the sampling tube is designed to be inwardly folded to further prevent soil from falling out of the sampling tube when it is pulled out. Attached Figure Description

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-6 As shown, a soil sampler for ecological environment monitoring is disclosed, including a sampling tube 1. The bottom end of the sampling tube 1 is open and has an inwardly curved design. A detachable intermediate tube 2 is fixed to the top end of the sampling tube 1. A sleeve 3 is sleeved on the surface of the intermediate tube 2, and a side hole 301 is provided on the side wall of the sleeve 3. An insertion component 4 is provided inside the side hole 301. A positioning hole 202 for inserting the insertion component 4 is provided on the middle side wall of the intermediate tube 2. A movable rod 5 is slidably connected inside the intermediate tube 2, and a handle 6 is fixed to the top end of the movable rod 5. An impact rod 7 is fixed to the bottom end of the movable rod 5. A compaction component 8 is provided at the top end of the sampling tube 1 and the bottom end of the intermediate tube 2.

[0027] The top end of the sampling tube 1 is connected to an externally threaded connecting tube 10, and the bottom end of the intermediate tube 2 is provided with an internal thread. The bottom of the intermediate tube 2 is rotatably connected to the surface of the externally threaded connecting tube 10 through the thread.

[0028] The intermediate tube 2 and the external threaded connecting tube 10 are connected by threads, which allows the intermediate tube 2 to be disassembled from the top of the sampling tube 1, making it easy to replace the sampling tube 1. In addition, after disassembling the sampling tube 1, it is easy to clean the inside of the sampling tube 1.

[0029] The plug-in assembly 4 includes a plug rod 401 that passes through the inside of the side hole 301 and is slidably connected to the side hole 301. One end of the plug rod 401 located outside the sleeve 3 is fixed with an end cap 402. The end cap 402 and the outer wall of the sleeve 3 are fixedly connected with a tension spring 403. One end of the plug rod 401 located inside the sleeve 3 can be inserted into the positioning hole 202.

[0030] When the sleeve 3 is located at the positioning hole 202 and the insertion rod 401 is aligned with the positioning hole 202, the tension spring 403 will pull the end cap 402 and pull the insertion rod 401 into the positioning hole 202, thereby fixing the sleeve 3. At this time, the sliding movable rod 5 will cause the impact rod 7 at the bottom of the movable rod 5 to strike the top of the sleeve 3, thereby pushing the intermediate tube 2 and the sampling tube 1 downward, so that the sampling tube 1 can be inserted into the soil layer.

[0031] A pull ring is fixedly connected to the surface of the end cap 402. This allows the end cap 402 to be pulled by the pull ring, which separates the insertion rod 401 from the positioning hole 202, and then the sleeve 3 can be slid downwards along the surface of the intermediate tube 2.

[0032] Two symmetrical strip grooves 201 are provided on the side wall of the intermediate tube 2, and the two ends of the impact rod 7 are slidably connected to the two strip grooves 201.

[0033] The impact rod 7 can only slide up and down along the strip groove 201, which serves as a guide and positioning mechanism.

[0034] Two foot pedals 9 are fixed to both sides of the bottom end of the intermediate tube 2, and the surface of the foot pedals 9 is provided with anti-slip texture. This makes it easy to insert the sampling tube 1 into the soil layer by stepping on the foot pedals 9.

[0035] The compaction assembly 8 includes a pressure plate 802 located inside the sampling tube 1, and a stop bar 801 is fixed in the middle of the upper surface of the pressure plate 802, with the top end of the stop bar 801 extending into the interior of the intermediate tube 2.

[0036] like Figure 5 As shown, when the sleeve 3 is at the bottom of the intermediate tube 2, when the movable rod 5 is slid up and down, the impact rod 7 at the bottom of the movable rod 5 can hit the top of the stop rod 801, thereby causing the pressure plate 802 to descend along the sampling tube 1 and compact the soil sample in the sampling tube 1 using the pressure plate 802.

[0037] Working principle: Place the bottom end of the sampling tube 1 on the soil surface, then slide the movable rod 5 up and down using the handle 6. Use the impact rod 7 to strike the sleeve 3 fixed on the surface of the intermediate tube 2, so that the sampling tube 1 is inserted into the soil. Then pull the insertion rod 401 out of the positioning hole 202, so that the sleeve 3 slides down to the bottom end of the intermediate tube 2. Continue to slide the movable rod 5 up and down, and use the impact rod 7 to strike the top of the stop rod 801. The pressure plate 802 compacts the soil inside the sampling tube 1. Finally, rotate the sampling tube 1. Because the bottom end of the sampling tube 1 has an inwardly curved design, when the sampling tube 1 is pulled out, the soil inside the sampling tube 1 can be completely taken out.

[0038] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
