Description
Technical Field
[0001] This utility model relates to the field of sampling device technology, and in particular to a sampling device for underground bud bank of alpine grassland vegetation. Background Technology
[0002] Alpine grassland vegetation is a type of grassland that develops in cold environments on plateaus and high mountains. The alpine grasslands in the middle section of the northern foothills of the Qilian Mountains are distributed in a high-altitude, low-heat environment. For a long time, harsh natural factors and long-term seasonal overgrazing have led to the emergence of a large number of special micro-patterns—rodent mounds—embedded in the alpine meadows by rodent disturbance, which have a strong disturbance effect on the grassland ecosystem.
[0003] After many ecosystems are subjected to destructive disturbances, the recovery of biomass and the reconstruction of the ecosystem mainly depend on bud banks. By sampling and testing underground bud banks, we can determine the role of plant bud banks in vegetation restoration and succession. When sampling, we need to select a variety of samples for comparison, which requires carrying multiple sampling tools or multiple storage tools. Carrying too much stuff when walking in high-altitude areas is not only time-consuming and laborious, but also increases the risk of altitude sickness and is not safe. Utility Model Content

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0021] like Figures 1 to 5 As shown, this application provides a sampling device for underground bud bank of alpine grassland vegetation, including a support cylinder 100 and a sampling component 200, which is used to collect soil samples from underground rodent mounds. The sampling assembly 200 includes a moving rod 210 and a sampling cylinder 220; The sampling cylinder 220 is a hollow cylinder with an opening at one end. A moving rod 210 is fixed to its closed end, and a rotating plate 211 is fixed to the unused end of the moving rod 210. The sampling cylinder 220 is rotated by rotating the rotating plate 211. The size of the rotating plate 211 is larger than the through hole size of the support cylinder 100. In other words, the rotating plate 211 can prevent the sampling cylinder 220 from detaching from the support cylinder 100. The support cylinder 100 is a hollow cylinder with an opening at one end near the opening of the sampling cylinder 220. That is, the openings of the support cylinder 100 and the sampling cylinder 220 face the same direction. The unused end of the support cylinder 100 has a through hole. The sampling cylinder 220 is located inside the support cylinder 100. The unused end of the moving rod 210 extends into the through hole and extends above the support cylinder 100. The sampling tube 220 is detachably connected to three telescopic plates 223. The sampling tube 220 has multiple reserved cavities 221. One telescopic plate 223 is inserted into one reserved cavity 221. The three telescopic plates 223 divide the interior of the sampling tube 220 into three independent sampling spaces.
[0022] It should be noted that before sampling, the three telescopic plates 223 are removed one by one. After the soil sampling of the first sampling area is completed, the uppermost telescopic plate 223 is inserted into the reserved cavity 221 inside the sampling tube 220. This operation is repeated to achieve independent storage of samples from the three sampling areas, reduce the space occupied by the samples, reduce the weight of the items carried, and improve the safety of sampling.
[0023] Specifically, such as Figures 1 to 5 As shown, a toothed plate 230 is fixed on the open end of the sampling tube 220. The toothed plate 230 is composed of multiple triangular blocks that are evenly spaced. The toothed plate 230 can increase the contact force with the soil, making the sampling process more labor-saving. It can dig up the underground part and the above-ground plants together. During the downward movement, the distance between the sampling tube (220) and the above-ground plants is controlled, and the above-ground plants are not damaged during the sampling process.
[0024] Specifically, such as Figures 1 to 5 As shown, the telescopic plate 223 is composed of multiple rectangular sleeves. The multiple sleeves slide together in sequence from large to small. When it moves to the maximum extent, the multiple sleeves are locked together and are not easy to fall off. The largest sleeve is far away from the inner wall of the sampling cylinder 220. The largest sleeve can be embedded in the reserved cavity 221, and the smallest sleeve is close to the inner wall of the sampling cylinder 220.
[0025] It is easy to understand that the telescopic plate 223 is composed of multiple sleeves. When not isolated, it occupies a small space and does not affect the sampling quality. After sampling, the largest sleeve can be pulled to fit into the reserved cavity 221. Furthermore, the top of the sampling tube 220 and the bottom of each telescopic plate 223 are fixed with protective plates to protect the plants on the ground. In this way, when the sampling tube 220 moves down, space is left for the plants on the ground, and the last set of telescopic plates 223 does not need to be equipped with protective plates.
[0026] Specifically, such as Figures 1 to 5 As shown, the sampling assembly 200 also includes an air inlet pipe 240; The reserved cavity 221 is a rectangular cavity, and two gas soft bags 222 are fixed in each reserved cavity 221. There are two telescopic plates 223 in one reserved cavity 221. One telescopic plate 223 is connected to the bottom of one gas soft bag 222. The largest sleeve in the telescopic plate 223 is in contact with the gas soft bag 222. In this way, it is not easy to squeeze the gas soft bag 222. The air inlet pipe 240 is used to inflate the gas soft bag 222.
[0027] Specifically, such as Figures 1 to 5As shown, the air inlet pipe 240 is fixed inside the sampling cylinder 220. One end of the air inlet pipe 240 is connected to the air pump, which is fixed to the side of the support cylinder 100. The support cylinder 100 has a through hole on its side, and the air inlet pipe 240 is located inside the through hole. The air inlet pipe 240 is a telescopic pipe and can extend and retract with the movement of the sampling cylinder 220. Three branch pipes 241 are fixed on the air inlet pipe 240. Two air delivery pipes 2411 are fixed on each branch pipe 241. The empty end of one air delivery pipe 2411 extends into a gas soft bag 222. The connection between the air delivery pipe 2411 and the gas soft bag 222 is airtight.
[0028] It is easy to understand that by introducing air into the air inlet pipe 240 through the air pump, the gas soft bag 222 can be inflated, causing it to expand and drive the telescopic plate 223 to move, thus isolating each layer of soil sample.
[0029] Specifically, such as Figures 3 to 5 As shown, each of the branch pipes 241 is fixed with a valve. When the valve of one branch pipe 241 is open, the valves of the other two branch pipes 241 are closed.
[0030] It should be noted that when taking samples, the valves of the three branch pipes 241 are opened sequentially from top to bottom, and when taking out samples, the valves of the three branch pipes 241 are opened sequentially from bottom to top.
[0031] Specifically, such as Figures 2 to 5 As shown, when the two gas bladders 222 in one of the reserved cavities 221 are inflated, they can drive the two telescopic plates 223 to move towards each other and cause the two telescopic plates 223 to collide with each other.
[0032] It is easy to understand that when the gas soft bag 222 expands, it causes the telescopic plate 223 to move towards each other; conversely, when the gas soft bag 222 contracts, it causes the telescopic plate 223 to move away from each other.
[0033] In the above embodiment, the support cylinder 100 is placed against the ground, and the sampling cylinder 220 is brought into contact with the soil. By rotating the rotating plate 211, the sampling cylinder 220 is driven into the soil to begin sampling the soil in the new mouse mound area. The sampling cylinder 220 is continuously rotated to dig up the underground part and the above-ground plants together, keeping the connection intact, so as to facilitate bringing them back to the laboratory for underground bud bank identification and statistics. After completing the soil sampling of this area, the sampling cylinder 220 is pulled upward, and air is introduced into the air inlet pipe 240 through the air pump. The valve of the uppermost branch pipe 241 is opened, so that the two gas soft bags 222 in the uppermost reserved cavity 221 are quickly inflated. This causes the two telescopic plates 223 to move towards each other and abut against each other, isolating the sampled soil and making it less likely to be mixed with other samples. When sampling the soil in the other two areas, the above sampling method can be repeated. This can achieve independent storage of samples from different areas without occupying external space, and multiple independent sampling spaces do not come into contact with each other, which can ensure the accuracy of the samples and thus improve the accuracy of the test results. In some embodiments of this application, such as Figures 1 to 9 As shown, an annular marking seat 110 is fixed to the side of the support cylinder 100. The marking seat 110 is filled with pigment. Multiple nozzles 111 are fixed to one end of the marking seat 110 near the ground. The nozzles 111 are used to spray pigment to mark the sampling area. A booster tube 114 is fixed on the marker base 110. One end of the booster tube 114 extends into the marker base 110, and the other end of the booster tube 114 is connected to a micro booster pump, which is fixed to the side of the marker base 110.
[0034] Specifically, such as Figures 6 to 8 As shown, the marking base 110 is fixed with six partitions 112, and the marking base 110 is divided into six storage spaces by the six partitions 112, with two adjacent storage spaces forming a group; The marker base 110 has three sets of storage spaces, and each set of storage spaces contains a different pigment color to distinguish different sampling areas. The three different pigment colors are sufficient to make the difference, and colors with high saturation are preferred.
[0035] It is worth noting that during sampling, the surface disturbed by underground rodents needs to be divided into three types of sampling areas based on the characteristics of the surface landscape of the survey area, the looseness of the soil in the rodent mounds, the height of the rodent mounds, the vegetation cover, and the composition of plant species. These areas are: new rodent mounds covered with freshly excavated soil, old rodent mounds without freshly excavated soil and a small amount of newly grown vegetation, and abandoned rodent mounds with abandoned burrow entrances. The bare spots are covered with a large amount of vegetation. By sampling from these three different types of sampling areas, the accuracy of the survey results can be ensured. Different types of sampling areas are marked by spraying different pigments to avoid omissions.
[0036] Specifically, such as Figures 6 to 9As shown, an annular vent pipe 113 is fixed on the marking base 110, and one end of the pressurization pipe 114 is connected to the vent pipe 113. Three air guide pipes 1131 are fixed on the vent pipe 113. Each air guide pipe 1131 is fixed with a valve. A distribution pipe 1132 is fixed to the unused end of one air guide pipe 1131. One distribution pipe 1132 is used to ventilate a group of storage spaces. Each distribution pipe 1132 is fixed with two air outlets. One air outlet of one distribution pipe 1132 extends into a storage space.
[0037] Based on the above embodiments, during the sampling process of a region, the valve of one air duct 1131 is opened while the valves of the other air ducts 1131 are closed. Gas is introduced into the booster pipe 114 by a booster pump, causing the pigment in that storage space to be sprayed out through the nozzle 111, thus marking the region. Similarly, the above operation can be repeated when sampling other regions. This allows for marking of the sampling area during the sampling process, reducing workflow and improving work efficiency.
[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
