Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, specifically a rapid soil testing device for field surveys. Background Technology

[0002] Soil field surveys are the process of systematically acquiring soil information through on-site observation, measurement, sampling, and recording in natural environments. This involves observing the vertical stratification of soil from top to bottom by excavating soil profiles or utilizing natural profiles. Rapid soil testing equipment is an important tool in environmental monitoring, agricultural management, and contaminated site assessment. It can quickly obtain key soil parameters on-site, significantly improving survey efficiency.

[0003] Application No. 202420464009.7 discloses a rapid soil pollution detection device. This patent includes a guide hole on a fixed plate, the guide hole extending longitudinally through the fixed plate; a detection rod extending vertically through the guide hole, with a pressure head at the top of the detection rod; and multiple sensors arranged along the axis of the detection rod on its surface, with the sensors and the outer surface of the detection rod on the same plane. This utility model features a simple overall structure, convenient installation and portability, and allows for rapid installation, disassembly, and recycling. By setting a detection rod and sensors on it, rapid soil detection can be achieved. Furthermore, by using multiple sensors on the detection rod, soil pollution can be detected at different depths.

[0004] The above comparison document shows that the soil was quickly tested by workers manually inserting a testing rod into the soil. However, this testing method makes it difficult to ensure that the testing rod is inserted vertically into the soil. In this case, the verticality deviation will cause the testing depth to be misaligned, and the unstable support will also cause the testing rod to tilt and shake, which will lead to data distortion and affect the testing quality. Utility Model Content

[0005] The purpose of this invention is to provide a rapid detection device for soil field surveys to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid soil field survey detection device, comprising a base, an electric push column, a base, and a detection rod. The electric push column is installed on both sides of the top of the inner wall of the base, and the output end of the electric push column is connected to the base. A detection rod is installed in the middle of the bottom end of the base. A detection probe is provided inside the bottom end of the detection rod. A transmission rod is provided on the outer side of the bottom end of the base, and a fixing component is slidably connected inside the top end of the transmission rod. A slip ring is fixedly connected to the bottom end of the transmission rod, and a rotating rod is rotatably connected to the outer side of the bottom end of the slip ring. A support seat is rotatably connected to the bottom end of the rotating rod, and a threaded insert is threadedly connected inside the support seat.

[0007] By moving the support base to a designated position, the support area between the base and the ground is increased, thereby improving its support stability.

[0008] Preferably, the transmission rods are distributed at equal angles, the top of the base has an internal movable hole into which the transmission rods extend, and the top of the base has an external fixing hole corresponding to the fixing member.

[0009] By pushing the fastener so that one side of its outer wall is inserted into the base, and then starting the electric push column, since the output end of the electric push column is connected to the base, the retraction of the electric push column will cause the base to move together.

[0010] Preferably, the inner wall of the slip ring is slidably connected to a slide rail, and the inner wall of the slide rail is welded to the base. The slide rail can guide the slide rail to move in a straight line, and the slide rail is triangularly distributed.

[0011] The slip ring moves smoothly by being guided by a slide rail.

[0012] Preferably, a limiting rod is connected to the middle of the outer wall of the support base, and a limiting column is slidably connected to the outer wall of the limiting rod, and one side of the outer wall of the limiting column is connected to the bottom end of the base.

[0013] By moving the limit rod along the limit post, the support seat is guided to move in a straight line.

[0014] Preferably, a fixing column is welded to the outer side of the top of the base, and the fixing columns are distributed at equal angles. A fixing groove is opened inside the top of the fixing column. The fixing member has a "T" shaped structure, and both ends of the outer wall of the fixing member can be inserted into the fixing groove and the fixing hole.

[0015] By pushing the fixing component to detach one side from the base and inserting the fixing column on the other side, the transmission rod is limited to prevent it from moving further down. Then, the electric push column continues to retract, causing the base to move down, and the transmission rod will not move down with it.

[0016] Preferably, the bottom of the outer wall of the detection rod is provided with an outlet hole corresponding to the detection probe, and a fixing rod is connected to the side of the bottom of the detection rod close to the detection probe, and the fixing rod and the detection probe are evenly distributed.

[0017] By positioning the detection probe inside the detection rod, the probe will not come into contact with the soil and gravel during the downward movement of the detection rod.

[0018] Preferably, the outer wall of the fixed rod is slidably connected to a mounting plate, and the middle part of the outer wall of the mounting plate is connected to the detection probe. The top of the outer wall of the mounting plate is connected to an extension block, and the middle part of the outer wall of the detection rod has an outlet corresponding to the extension block.

[0019] The detection probe is moved out of the detection rod by the mounting plate and inserted into the soil for detection.

[0020] Preferably, an electric push rod is installed inside the bottom end of the base, and an electromagnet is connected to the output end of the electric push rod. The electromagnet and the extension block are magnetically connected.

[0021] By making the electromagnet and the extension block fit together in a magnetic connection, the electric push rod continues to extend and will generate a pushing force on the mounting plate, causing the mounting plate to move linearly along the fixed rod.

[0022] As can be seen from the above, the rapid soil field survey detection equipment provided by this utility model has the following beneficial effects.

[0023] 1. By moving the support base to a designated position, the support area between the base and the ground is increased, thereby improving its support stability. This allows the detection rod to be inserted vertically into the ground for testing, preventing the detection rod from affecting the testing quality due to verticality deviation. Furthermore, the deployment of the support assembly can be completed during the process of the detection rod moving down for testing.

[0024] 2. By positioning the detection probe inside the detection rod, the probe will not come into contact with the soil and gravel during the downward movement of the detection rod, thus protecting it from damage caused by impacts with gravel and extending its service life.

[0025] 3. The detection probe is moved out of the detection rod and inserted into the soil by the mounting plate. At this time, the detection probe can detect soil at different depths at the same time, thereby preventing cross-contamination of samples at different depths. Attached Figure Description

Detailed Implementation

[0035] 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.

[0036] Please see Figures 1-6This utility model provides a technical solution: a rapid soil field survey detection device, including a base 1, an electric push column 2, a base 3, and a detection rod 4. The electric push column 2 is installed on both sides of the top of the inner wall of the base 1, and the output end of the electric push column 2 is connected to the base 3. The detection rod 4 is installed in the middle of the bottom end of the base 3. A detection probe 5 is installed inside the bottom end of the detection rod 4. A transmission rod 6 is installed on the outer side of the bottom end of the base 3, and a fixing member 7 is slidably connected inside the top end of the transmission rod 6. A slip ring 8 is fixedly connected to the bottom end of the transmission rod 6, and a rotating rod 9 is rotatably connected to the outer side of the bottom end of the slip ring 8. A support seat 10 is rotatably connected to the bottom end of the rotating rod 9, and a threaded insert rod 11 is threadedly connected inside the support seat 10. The transmission rods 6 are distributed at equal angles, and the top of the base 1... An movable hole is provided inside the end, and the transmission rod 6 extends into it. A fixing hole corresponding to the fixing member 7 is provided on the outer side of the top of the base 3. A slide rail 12 is slidably connected to the inner wall of the slip ring 8, and the inner wall of the slide rail 12 is welded to the base 1. The slide rail 12 can guide the slide rail 12 to move linearly, and the slide rail 12 is triangularly distributed. A limit rod 13 is connected to the middle of the outer wall of the support base 10, and a limit post 14 is slidably connected to the outer wall of the limit rod 13. One side of the outer wall of the limit post 14 is connected to the bottom end of the base 1. A fixing post 15 is welded to the outer side of the top of the base 1, and the fixing posts 15 are distributed at equal angles. A fixing groove is provided inside the top of the fixing post 15. The fixing member 7 has a "T" shaped structure, and both ends of the outer wall of the fixing member 7 can be inserted into the fixing groove and the fixing hole.

[0037] For specific implementation, please refer to Figures 1-3 First, move the base 1 to the designated location in the field. Then, push the fixing part 7 so that one side of its outer wall is inserted into the base 3. Then, start the electric push column 2. Since the output end of the electric push column 2 is connected to the base 3, the retraction of the electric push column 2 will drive the base 3 to move together. Then, the base 3 will drive the detection rod 4 and the transmission rod 6 to move down together.

[0038] See Figures 3-5 When the transmission rod 6 moves down, it will generate a thrust on the slip ring 8, causing the slip ring 8 to move down along the slide rail 12. At this time, the slide rail 12 guides the slip ring 8 to move smoothly. Since the bottom end of the slip ring 8 is rotatably connected to the rotating rod 9, the movement of the slip ring 8 will drive the rotating rod 9 to rotate. At this time, the angle between the rotating rod 9 and the slip ring 8 will change, which will then generate a thrust on the support seat 10, causing the support seat 10 to drive the threaded rod 11 and the limiting rod 13 to move away from the base 1. At this time, the limiting rod 13 moves along the limiting post 14, thereby guiding the support seat 10 to move in a straight line.

[0039] Until the support base 10 moves to the designated position, thereby increasing the support area between the base 1 and the ground and improving its support stability, and at this time, according to actual needs, the threaded rod 11 can be rotated downward to insert into the ground to reinforce the base 1, thereby reinforcing the base 1 to prevent the detection rod 4 from tipping over or moving, so that the detection rod 4 is inserted vertically into the ground for detection, thereby preventing the detection rod 4 from affecting the detection quality due to verticality deviation.

[0040] See Figure 5 and Figure 6 When the support base 10 unfolds and moves to the designated position, the bottom end of the detection rod 4 is still inside the base 1 and has not contacted the ground. Then, the fixing piece 7 is pushed so that one side is disconnected from the base 3 and the other side is inserted into the fixing column 15, thereby limiting the transmission rod 6 to prevent it from moving further down. After that, the electric push column 2 continues to retract and drive the base 3 to move down, so the transmission rod 6 will not move down with it. Thus, the unfolding of the support assembly is completed during the detection process when the detection rod 4 moves down to perform the detection.

[0041] See Figure 3 , Figure 7 and Figure 8 The bottom of the outer wall of the detection rod 4 has an outlet hole corresponding to the detection probe 5. A fixing rod 16 is connected to the inside of the bottom of the detection rod 4 near the detection probe 5, and the fixing rod 16 and the detection probe 5 are evenly distributed. A mounting plate 17 is slidably connected to the outer wall of the fixing rod 16, and the middle of the outer wall of the mounting plate 17 is connected to the detection probe 5. An extension block 18 is connected to the top of the outer wall of the mounting plate 17, and an outlet corresponding to the extension block 18 is opened in the middle of the outer wall of the detection rod 4. An electric push rod 19 is installed inside the bottom of the base 1, and an electromagnet 20 is connected to the output end of the electric push rod 19. The electromagnet 20 and the extension block 18 are magnetically connected.

[0042] In practice, when the electric push column 2 retracts, causing the detection rod 4 to continue to move downwards and insert into the ground, the detection probe 5 is located inside the detection rod 4 at this time. During the downward movement of the detection rod 4, the detection probe 5 will not come into contact with the soil and gravel, thus protecting the detection probe 5 from being damaged by collisions with gravel, thereby extending the service life of the detection probe 5.

[0043] See Figure 7 and Figure 8When the detection rod 4 moves down to the designated depth, the electric push rod 19 inside the bottom of the base 1 is activated. The electric push rod 19 extends and drives the electromagnet 20 to move closer to the detection rod 4 until the electromagnet 20 and the extension block 18 are magnetically connected. Then, the electric push rod 19 continues to extend and will generate a pushing force on the mounting plate 17, causing the mounting plate 17 to move linearly along the fixed rod 16 until the mounting plate 17 drives the detection probe 5 to move out of the detection rod 4 and insert into the soil. Since the detection probe 5 is evenly distributed from top to bottom, the detection probe 5 can simultaneously detect parameters such as soil temperature, water content and heavy metal content at different depths, thereby preventing cross-contamination of samples at different depths.

[0044] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
