Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of soil sampling equipment, and more particularly, to a surface soil sampler. Background Art
[0002] Surface soil sampling is an important task in soil environmental monitoring. Sometimes, a core sampler is used when sampling surface soil. When using a core sampler for surface soil sampling, the operator can press the core sampler downward through the handle to insert the core sampler into the ground. When pressing the handle downward, the operator can either press the handle by hand or use tools such as a hammer to strike the handle. When using the above methods to press the handle downward to insert the core sampler into the ground for soil sampling, the labor intensity of the operator is often high, and the efficiency of soil sampling is low, especially when the land is relatively hard and soil sampling needs to be carried out at many sampling points. Summary of the Invention
[0003] The purpose of the utility model is to provide a surface soil sampler to overcome the problems of high labor intensity of the operator and low soil sampling efficiency existing in the core sampler in the prior art during soil sampling.
[0004] The utility model is realized by the following technical solutions: a surface soil sampler includes an operating rod. The operating rod includes a vertical rod, and a horizontal plate is fixedly installed at the bottom of the vertical rod. A limiting hole is opened in the middle of the horizontal plate. A connecting plate is sleeved on the vertical rod. The connecting plate is fixedly connected to a pressing block. A threaded joint that can be inserted into the limiting hole is installed at the bottom of the pressing block. The threaded joint is provided with an external thread. The threaded joint is threadedly connected to a core sampler. An internal thread that cooperates with the threaded joint is opened on the upper side of the inner wall of the core sampler. A ring-shaped boss is provided on the lower side of the inner wall of the core sampler, and a sampling cylinder is installed on the boss.
[0005] Further, a ring-shaped cutting edge is provided at the bottom of the core sampler.
[0006] Further, the operating rod further includes a cross rod. One end of the cross rod is fixedly connected to the top of the vertical rod. The cross rod, the vertical rod, and the horizontal plate form a U-shaped structure.
[0007] Further, the horizontal plate includes a limiting ring arranged above the limiting hole.
[0008] Further, a convex edge is provided at the top of the pressing block.
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0010] 1. The surface soil sampler of the present utility model presses the core cutter into the soil by stepping on it with the foot. When in use, first press the cross bar downward by hand to make the horizontal plate closely adhere to the ground horizontally, and then step on the pressing block downward with the foot to insert the core cutter into the ground to a certain depth. Compared with the current method of pressing the core cutter by hand and knocking it with a hammer, the present utility model can insert the core cutter into the ground more easily, reduce the labor intensity of the staff, and improve the efficiency of soil sampling. Especially when sampling soil on some relatively hard lands, the above advantages of the present utility model are more prominent.
[0011] 2. By setting the vertical rod and the horizontal plate, the present utility model can make the downward pressing process more stable when stepping on the pressing block with the foot, avoid the core cutter from tilting during the pressing process, and thus keep the core cutter being pressed downward in the vertical direction, making the soil sampling more accurate.

[0018] In order to enable those skilled in the art of the present technology to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the present utility model.
[0019] A surface soil sampler, comprising an operating rod 1, the operating rod 1 includes a vertical rod 2, the bottom of the vertical rod 2 is fixedly installed with a horizontal plate 3, the vertical rod 2 is perpendicular to the horizontal plate 3. By setting the operating rod 1, the present utility model is convenient to carry, and only need to hold the operating rod 1 by hand when moving. The operating rod 1 further includes a cross rod 12, one end of the cross rod 12 is fixedly connected to the top of the vertical rod 2, the cross rod 12 is perpendicular to the vertical rod 2, and the cross rod 12, the vertical rod 2 and the horizontal plate 3 form a U-shaped structure. By forming a U-shaped structure with the cross rod 12, the vertical rod 2 and the horizontal plate 3, the staff can better control the horizontal plate 3 to be horizontal by pressing the cross rod 12, and the structure of the operating rod 1 is simple, which also reduces the production cost of the present utility model.
[0020] By setting the vertical rod 2 and the horizontal plate 3, during work, the staff can press the cross rod 12 downward to make the horizontal plate 3 close to the ground and keep horizontal, and then the vertical rod 2 can be conveniently kept vertical. The pressing block 6 of the present utility model is sleeved on the vertical rod 2 through the connecting plate 5. When the vertical rod 2 is kept vertical, during the downward movement of the pressing block 6, it can also move in the vertical direction, so that the core cutter 8 connected to the pressing block 6 also moves vertically downward, making the soil sampling more accurate.
[0021] A limiting hole 4 is opened in the middle of the horizontal plate 3, and the threaded joint 7 at the bottom of the pressing block 6 and the core cutter 8 can be inserted into the limiting hole 4. When stepping on the pressing block 6 downward with the foot, the core cutter 8 will pass through the limiting hole 4 and insert into the ground until the connecting plate 5 contacts the horizontal plate 3. When the connecting plate 5 contacts the horizontal plate 3, the pressing block 6 and the core cutter 8 cannot be stepped on downward anymore. At this time, the top surface of the sampling cylinder 10 installed in the core cutter 8 is flush with the bottom surface of the horizontal plate 3, that is, the top surface of the sampling cylinder 10 is flush with the ground of the sampling area.
[0022] The horizontal plate 3 includes a limiting ring 13 arranged on the upper side of the limiting hole 4, and the inner cylinder of the limiting ring 13 is communicated with the limiting hole 4. By setting the limiting ring 13, the height of the limiting hole 4 is increased, and then the height of the threaded joint 7 can be increased, increasing the connection stability between the core cutter 8 and the threaded joint 7.
[0023] A connecting plate 5 is sleeved on the vertical rod 2, the connecting plate 5 is fixedly connected to the pressing block 6, and the pressing block 6 moves along the vertical rod 2 through the connecting plate 5. A threaded joint 7 that can be inserted into the limiting hole 4 is installed at the bottom of the pressing block 6, the threaded joint 7 is provided with an external thread, and the threaded joint 7 is threadedly connected to the core cutter 8. The inner wall of the upper side of the core cutter 8 is provided with an internal thread that cooperates with the threaded joint 7. By threadedly connecting the core cutter 8 and the threaded joint 7, the disassembly and assembly of the core cutter 8 are convenient.
[0024] A circular boss 9 in a ring shape is provided on the lower side of the inner wall of the said core cutter 8. A sampling cylinder 10 is installed on the boss 9. After the core cutter 8 is threadedly connected to the threaded joint 7, the sampling cylinder 10 is between the boss 9 and the threaded joint 7. The bottom surface of the threaded joint 7 can abut against the sampling cylinder 10, that is, the top surface and the bottom surface of the sampling cylinder 10 are in close contact with the threaded joint 7 and the boss 9 respectively, so that the sampling cylinder 10 is fastened inside the core cutter 8. We can reasonably design the height of the threaded joint 7. When the bottom surface of the connecting plate 5 contacts the horizontal plate 3 and cannot move downward any further, the bottom surface of the threaded joint 7 should be flush with the bottom surface of the horizontal plate 3, and at this time, the bottom surface of the threaded joint 7 abuts against the top surface of the sampling cylinder 10.
[0025] The core cutter 8 is in a cylindrical shape, and a cutting edge 11 in a ring shape is provided at the bottom of the core cutter 8. By providing the cutting edge 11 in the present utility model, the core cutter 8 can be more easily pressed into the ground.
[0026] The outer diameter of the sampling cylinder 10 is slightly smaller than the outer diameter of the boss 9. The core cutter 8 is divided into an upper part and a lower part. The outer diameter and the inner diameter of the upper part are respectively larger than the outer diameter and the inner diameter of the lower part. The internal thread of the core cutter 8 is provided on the inner wall of the upper part. By making the outer diameter of the sampling cylinder 10 slightly smaller than the outer diameter of the boss 9 and dividing the core cutter 8 into an upper part and a lower part in the present utility model, the sampling cylinder 10 can be placed into the core cutter 8 and taken out from the core cutter 8 more easily. The sampling cylinder 10 described in the present utility model can be used as a disposable consumable, and the sampled soil is in the sampling cylinder 10.
[0027] A convex edge 14 is provided at the top of the pressing block 6. By providing the convex edge 14 at the top of the pressing block 6 in the present utility model, the area of the top surface of the pressing block 6 can be increased, and further the stepping area of the pressing block 6 can be increased, making the use of the present utility model more convenient.
[0028] The working process of the present utility model:
[0029] First, place the sampling cylinder 10 onto the boss 9 inside the core cutter 8 through the top opening of the core cutter 8, and threadedly install the core cutter 8 onto the threaded joint 7 of the pressing block 6 to make the threaded joint 7 abut against the sampling cylinder 10. Then place the present utility model on the ground to be sampled. By pressing down the cross bar 12, the horizontal plate 3 is horizontally placed and closely abuts against the ground. Then step on the pressing plate with the foot to make the pressing plate move vertically downward along the vertical rod 2, thereby driving the core cutter 8 and the sampling cylinder 10 inside the core cutter 8 to move vertically downward and penetrate through the limiting hole 4 and insert into the ground until the connecting plate 5 contacts the top surface of the limiting ring 13 on the horizontal plate 3. At this time, the top surface of the sampling cylinder 10 is flush with the bottom surface of the horizontal plate 3, and the sampled soil is inserted into the sampling cylinder 10 inside the core cutter 8. Then pull out the core cutter 8 from the ground through the cross bar 12, and by rotating the core cutter 8, separate the core cutter 8 from the threaded joint 7. Finally, remove the sampling cylinder 10 from the top opening of the core cutter 8.
