Technical Field

[0001] The utility model relates to the technical field of geographic information data acquisition, and particularly relates to a tool for acquiring surveying and mapping geographic information data. Background Art

[0002] Geographic information is the geographic meaning contained and expressed by geographic data, and is the general term for numbers, texts, images, graphics, etc. related to the quantity, quality, nature, distribution characteristics, connections and laws of substances related to geographic environmental elements. Surveying and mapping is to measure, collect and draw maps of the shape, size, spatial position and its attributes of natural geographic elements or surface artificial facilities. In the process of surveying and mapping geographic information data, it is also necessary to collect soil information to obtain geographic information data such as soil attributes, so a collection tool is required.

[0003] At present, when the existing collection tools are used to collect soil with poor cohesion, because the soil with poor cohesion is relatively soft and has good fluidity, during the operation, the vibration and impact received by the tools may cause the reduction of the friction force between soil particles, resulting in the leakage of the collected soil, and only a very small amount of soil remains, which cannot meet the soil sample collection requirements. Therefore, this application provides a tool for acquiring surveying and mapping geographic information data to meet the requirements. Summary of the Utility Model

Detailed Embodiments

[0027] The following describes in detail a surveying and mapping geographic information data acquisition tool provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0028] As Figure 2 , Figure 3 and Figure 4 shown, an embodiment of the present invention provides a surveying and mapping geographic information data acquisition tool, including: a support sleeve 1; a rotating rod 3 disposed within the support sleeve 1; a rotating plate 4 fixedly sleeved on the rotating rod 3; a storage cylinder 5 disposed below the rotating rod 3; a drill bit 6 disposed at the bottom of the storage cylinder 5; a storage cavity 7 disposed within the storage cylinder 5; two soil inlets 9 disposed on the left and right sides of the storage cylinder 5; two leakage prevention parts 10 disposed within the soil inlets 9, and the two leakage prevention parts 10 are symmetrically disposed along the vertical plane of the horizontal center of the soil inlet 9. The leakage prevention part 10 includes: a blocking plate 102 rotatably disposed on the inner wall of the soil inlet 9; a support rod 101 movably disposed on the blocking plate 102; a groove 104 disposed within the storage cylinder 5; a tensile spring 103 disposed within the groove 104; and one side of the support rod 101 extends into the groove 104 and is connected to the tensile spring 103.

[0029] As the drill bit 6 penetrates deeper into the ground, under the dual action of the drilling pressure and its own gravity: when the drill bit 6 contacts the soil surface, it first generates shear force and compressive force on the surface soil, which will cause the connection between soil particles to be damaged, cracks begin to form and spread around. The continuous application of the drilling pressure enables the drill bit 6 to continue to penetrate. In this process, the soil particles are crushed and separated; as the drill bit 6 penetrates deeper, the damaged soil particles begin to flow under the push of the drilling pressure. Due to the natural stacking angle of the soil and the influence of gravity, the soil particles tend to move along the path of least resistance. At this time, the soil inlet 9 becomes a natural flow channel. The drilling pressure not only pushes the soil in front but also indirectly affects the soil in the area near the soil inlet 9 through the principle of soil continuity, causing it to move towards the soil inlet 9.

[0030] It starts to pour into the soil inlet 9. As the amount of soil increases, the pressure exerted on the inner wall of the soil inlet 9 also gradually increases. Since the baffle 102 is rotatably arranged on the inner wall of the soil inlet 9, as the soil pressure accumulates, it begins to overcome the elastic force of the tension spring 103 and rotate the two baffles 102 along the inner wall of the soil inlet 9. Although the tension spring 103 attempts to keep the baffle 102 in the closed state, when the thrust of the soil is large enough, it can cause the baffle 102 to rotate along the inner wall of the soil inlet 9 until it fits against the inner wall of the soil inlet 9, opening the soil inlet 9 and creating a passage for the soil to enter the storage cavity 7. The soil smoothly passes through the soil inlet 9 under the push of the pressure and enters the lower storage cavity 7. At this time, the left and right sides of the storage cavity 7 gradually expand outward along the soil inlet 9, which helps the soil to transition smoothly, reduces blockage or accumulation, and ensures a smooth collection process. During the soil sampling process, the support rod 101 and the tension spring 103 work together to form a dynamic balance mechanism. The continuous pressure of the soil causes the baffle 102 to remain open to a certain extent, allowing the soil to continue to enter. Once the soil pressure decreases, such as when the drilling stops or the lifting device is lifted, the restoring force of the tension spring 103 will push the baffle 102 back to the initial closed position to prevent the collected soil from flowing back or leaking.

[0031] As Figure 3 and Figure 4 shown, it also includes: the axis of the tension spring 103 is parallel to the extension line of the end of the support rod 101 entering the groove 104, and the tension spring 103 is perpendicular to the inner cavity of the groove 104 it is connected to.

[0032] When no external force is applied, the two baffle plates 102 are kept in a relatively abutting state by the action of the tension spring 103 and the support rod 101. At this time, the soil inlet 9 is in a natural closed state to prevent soil from accidentally entering or leaking during non-sampling states. When the drill bit 6 is inserted into the soil, the soil pushes the two baffle plates 102 to rotate along the inner wall of the soil inlet 9 until they fit against the inner wall of the soil inlet 9, thereby opening the soil inlet 9 and allowing the soil to smoothly pass through the soil inlet 9 and enter the storage cavity 7 below; after the soil sampling is completed, the external pressure is reduced, and the elastic force of the tension spring 103 causes the baffle plates 102 to reset, closing the soil inlet 9 again to ensure that the soil sample in the storage cavity 7 will not leak due to vibration or movement.

[0033] As Figure 3 shown, it also includes: both the left and right sides of the storage cavity 7 gradually incline and expand outward along the direction of the soil inlet 9. This allows the soil sample to smoothly transition when entering the storage cavity 7, reducing blockage or accumulation of the sample during the soil inlet process. As the internal space of the soil inlet 9 gradually expands to the storage cavity 7, soil samples of different volumes and densities can be more efficiently received, improving the collection efficiency.

[0034] As Figure 3 shown, it also includes: the outside of the soil inlet 9 gradually inclines and contracts inward along the direction of the storage cavity 7. This helps the soil to smoothly transition when entering the storage cavity 7, reducing blockage or suction effects caused by sudden spatial changes during the sampling process, enabling the sample to be continuously and evenly collected, and enhancing the representativeness and integrity of the sample.

[0035] As Figure 2 and Figure 3 shown, it also includes: a cover plate 8, detachably arranged on the top of the storage cylinder 5 and connected to the rotating rod 3. By setting the cover plate 8, detachable connections such as threaded connections, snap - on designs, or hinges and locks can be used to pour out the collected soil, facilitating subsequent operations.

[0036] As Figure 1 and Figure 5 shown, it also includes: a plurality of auxiliary parts 2, arranged at the bottom of the support sleeve 1. The auxiliary part 2 includes: an auxiliary plate 21, rotatably arranged at the bottom of the support sleeve 1. The auxiliary part 2 is designed to increase the stability when the tool contacts the ground. Especially when operating on uneven or soft ground, through the contact between the auxiliary plate 21 and the ground, the overall weight of the tool can be effectively dispersed, reducing sinking or tilting caused by excessive single - point stress, and ensuring the smooth progress of the sampling process.

[0037] As Figure 5As shown, it further includes: a placement groove 22 provided at the bottom of the auxiliary plate 21. The placement groove 22 can be used to install additional components such as the insertion rod 23, which may be used for deeper sampling of soil samples, fixing the position of tools, or assisting in other specific surveying tasks.

[0038] As Figure 5 shown, it further includes: an insertion rod 23 rotatably arranged in the placement groove 22. The insertion rod 23 can be inserted into the ground as a temporary anchoring point. Especially when operating on soft or uneven ground, it can effectively prevent the collection tool from shaking or tipping due to external forces, ensuring the stability and accuracy of the collection process.

[0039] As Figure 3 shown, it further includes: an inlet 9 communicating with the storage cavity 7. The design of the anti-leakage part 10 complements the communication between the inlet 9 and the storage cavity 7. The blocking plate 102 cooperates with the tension spring 103 to reduce sample overflow during the soil sample collection process, while allowing the soil sample to pass through smoothly, ensuring the effectiveness and integrity of sample collection.

[0040] As Figure 2 shown, it further includes: a rotating plate 4 located inside the support sleeve 1 and threadedly connected to the support sleeve 1. The threaded connection facilitates the rapid on-site assembly and disassembly of the tool, which is beneficial for equipment maintenance, cleaning, or replacing damaged parts. For a surveying team working in the field for a long time, it improves work efficiency and reduces maintenance costs.

[0041] For the technical solution provided by the present utility model, rotate the auxiliary plate 21 to be flush with the support sleeve 1, then rotate the insertion rod 23 to be vertical, place the support sleeve 1 in the area where soil needs to be collected, so that the insertion rod 23 is inserted into the soil, start rotating the rotating rod 3, drive the rotating plate 4 to move downward, and push the storage cylinder 5 and the drill bit 6 to move downward; when starting to collect, the soil enters the inlet 9. As the soil pressure increases, it pushes the blocking plate 102 to rotate along the inner wall of the inlet 9 until it fits with the inner wall of the inlet 9, thereby opening the inlet 9 and allowing the soil to enter the storage cavity 7. When enough soil samples are collected in the storage cavity 7, stop drilling, reverse the rotating rod 3, drive the rotating plate 4 to move upward, pull the storage cylinder 5 and the drill bit 6 to move upward, and at the same time, through the tension spring 103, push the support rod 101 to reset the blocking plate 102 and close the inlet 9; take out the storage cylinder 5 from the support sleeve 1, then remove the cover plate 8, and take out the collected soil sample for subsequent processing.

[0042] The present utility model covers any alternatives, modifications, equivalent methods, and solutions made to the essence and scope of the present utility model. For the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model, and those skilled in the art can fully understand the present utility model without the description of these details. In addition, well-known methods, processes, procedures, components, and circuits are not described in detail to avoid unnecessary confusion to the essence of the present utility model.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
