Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, specifically a handheld soil sampling device for environmental monitoring. Background Technology

[0002] Soil sampling refers to the process of obtaining soil samples from a specific area or location for the purpose of analyzing the physical, chemical, and biological properties of the soil. This process is widely used in fields such as environmental monitoring, agricultural production, soil pollution assessment, and land use planning. By collecting representative samples, soil fertility, pollution levels, soil structure, and suitability can be determined, providing a reliable basis for scientific policy implementation, environmental protection, and resource management.

[0003] An investigation revealed that a Chinese utility model patent discloses a handheld soil sampling device for environmental monitoring (publication number: CN217849877U), which includes a sampling tube. A fixed base is movably installed inside the sampling tube, and a fixed post is screwed onto the surface of the fixed base. The end of the fixed post away from the fixed base is screwed onto the handle, and the end of the fixed base is welded to the stud. An extrusion plate is fixedly installed on the bottom surface of the fixed base. An adjustment port is opened on the side wall of the sampling tube, and a stud is inserted inside the adjustment port. A sampling area is opened inside the sampling tube, and an inclined tip is provided at the bottom of the sampling area.

[0004] While the aforementioned patent allows the handle to be pressed down when carrying the device, causing the extrusion plate to move to the bottom of the sampling cylinder and the fixing column to retract inside the sampling cylinder, thus reducing the size and making it easier to carry, the sampling process relies heavily on manual operation, which can easily lead to inconsistent sampling depths, resulting in significant errors and affecting the representativeness of the samples and the accuracy of subsequent analysis results.

[0005] Therefore, this utility model provides a handheld soil sampling device for environmental monitoring to solve the above problems. Utility Model Content

The limiting component includes an inner rod, the outer surface of which is slidably connected to the inside of a guide groove. A limiting plate is fixedly connected to the bottom end of the inner rod, and a control rod is fixedly connected to the top end of the inner rod.

[0008] As a preferred technical solution of this application, the fixing component includes a threaded bolt, the outer surface of which is threadedly connected to one side of the outer surface of the positioning ring, one end of which is rotatably connected to a fixing ring via a bearing, and a force-bearing plate is fixedly connected to the bottom end of the inner wall of the fixing ring.

[0012] As a preferred technical solution of this application, a sampling cylinder is fixedly connected to the lower surface of the pressing plate around the guide groove, and an inclined end plate is fixedly connected to the bottom end of the sampling cylinder.

[0013] (III) Beneficial Effects 1. By using the limiting components, the fixing bolts can fix the downward extension position of the inner rod to control the position of the limiting plate inside the sampling tube, thereby limiting the sampling depth, ensuring the consistency of the sampling depth each time, reducing sampling errors, improving the representativeness of the sample and the accuracy of subsequent analysis results.

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a handheld soil sampling device for environmental monitoring, such as... Figures 1-4 As shown, the handheld environmental monitoring soil sampling device includes a pressing plate 1. A guide groove is provided in the middle of the upper surface of the pressing plate 1. A limit component is slidably connected inside the guide groove. A positioning ring 2 is fixedly connected to the upper surface of the pressing plate 1 around the guide groove. Fixing components are threadedly connected to both sides of the outer surface of the positioning ring 2. The limiting component includes an inner rod 3, the outer surface of which is slidably connected to the inside of the guide groove. A limiting plate 4 is fixedly connected to the bottom end of the inner rod 3, and a control rod 5 is fixedly connected to the top end of the inner rod 3. The limiting plate 4 can be moved to the required position inside the sampling cylinder 14 by the control rod 5 via the inner rod 3, and then fixed by the fixing bolt 13, thereby limiting the sampling depth, ensuring the consistency of the sampling depth each time, reducing sampling error, improving the representativeness of the sample and the accuracy of subsequent analysis results. At the same time, the limiting plate 4 can be continuously moved downward to push the collected sample out of the sampling cylinder 14, which facilitates the rapid removal of the sample and improves the convenience of operation and work efficiency.

[0019] The fixing component includes a threaded bolt 6, the outer surface of which is threaded to one side of the outer surface of the positioning ring 2. One end of the threaded bolt 6 is rotatably connected to a fixing ring 9 via a bearing 8. A force-bearing plate 10 is fixedly connected to the bottom end of the inner wall of the fixing ring 9. Tightening the threaded bolt 6 causes the fixing ring 9 to move outward, so that the force-bearing plate 10 is away from the bottom end of the outer cylinder 11, allowing the outer cylinder 11 to slide into the sampling cylinder 14. This facilitates storage and carrying according to actual needs, improving the portability of the equipment.

[0020] An outer cylinder 11 overlaps the upper surface of the load-bearing plate 10. A hand-held plate 12 is fixedly connected to the top of the outer cylinder 11. The outer cylinder 11 allows the operator to hold the hand-held plate 12 at a suitable height to operate the sampling cylinder 14, thereby reducing the workload.

[0021] The outer cylinder 11 has sliding grooves on both sides. The inside of the sliding grooves is slidably connected to the outer surface of the control rod 5. The sliding grooves facilitate the limiting and guiding of the control rod 5, allowing it to move up and down along the outer cylinder 11.

[0022] The bottom end of the outer cylinder 11 is threaded with a fixing bolt 13. The inner rod 3 has several threaded grooves on its surface that are compatible with the fixing bolt 13. By screwing the fixing bolt 13 into the corresponding threaded groove, the length of the inner rod 3 extending downward can be fixed.

[0023] A sampling cylinder 14 is fixedly connected to the lower surface of the pressing plate 1 around the guide groove. An inclined end plate 7 is fixedly connected to the bottom end of the sampling cylinder 14. The inclined end plate 7 facilitates the smooth entry of the sampling cylinder 14 into the soil and makes it easy to collect soil samples.

[0024] Working steps: First, the limiting plate 4 can be moved to the desired position inside the sampling cylinder 14 by controlling the control rod 5 via the inner rod 3. Then, the fixing bolt 13 is screwed into the corresponding threaded groove to fix the position of the inner rod 3. Next, the hand holding plate 12 is held and the foot pressing plate 1 is used to make the sampling cylinder 14 enter the soil through the inclined end plate 7 to collect the soil. Next, the limiting plate 4 is continuously moved down to push the collected sample out of the sampling cylinder 14. Finally, the threaded bolt 6 is screwed to move the fixing ring 9 outward so that the force plate 10 is away from the bottom of the outer cylinder 11, so that the outer cylinder 11 can slide into the sampling cylinder 14 for easy storage and carrying according to actual needs.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
