Description

Technical Field

[0001] This utility model belongs to the field of land engineering technology, and in particular relates to a soil sampling device for land engineering. Background Technology

[0002] In land engineering, a soil sampler is a tool used to collect soil samples. By obtaining soil samples from different strata, the soil sampler can accurately determine the geological conditions of a site, including soil layer distribution, thickness, and lithological variations, providing basic data for project site selection, design, and construction.

[0003] However, the above-mentioned device still has the following problems during implementation:

[0004] Existing technology makes soil samplers a tool used to collect soil samples in land engineering. However, common manual soil samplers require the user to push the soil sample out of the sampler with a push rod after the sample is collected. This process requires the user to press down hard with their palm, which is quite strenuous. Therefore, a soil sampling device for land engineering is proposed to solve the above problems. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides a soil sampling device for land engineering, which has the advantage of labor-saving soil sampling. It can overcome the above-mentioned problems or at least partially solve the problem that common manual soil samplers push the soil sample out of the sampler by pushing the sample rod after soil sampling, which requires the user to press hard with their palm, and this process is relatively labor-intensive.

[0006] This utility model is implemented as follows: a soil sampling device for land engineering includes a movable shell, a sampling tube, a T-shaped handle, a mating hole, and two fixing plates. The sampling tube is movably connected to the inner cavity of the movable shell, the top of the movable shell is fixedly connected to the bottom of the T-shaped handle, the mating hole is opened on the right side of the T-shaped handle, and the right side of the T-shaped handle is fixedly connected to the fixing plate.

[0007] The front side of the T-shaped grip is movably connected to a fixed shell, and the rear side of the fixed shell is fixedly connected to a fixed plate.

[0008] A fixing component is disposed within the inner cavity of the fixing shell.

[0009] As a preferred embodiment of this utility model, the surface of the movable shell is fixedly connected with three ground-inserting rods, and the surface of each ground-inserting rod is fixedly connected with a positioning plate. By setting the ground-inserting rods and positioning plates, when the movable shell comes into contact with the ground, the ground-inserting rods are inserted into the ground, thereby positioning the position of the movable shell, and the positioning plates can position the position of the ground-inserting rods.

[0010] As a preferred embodiment of this utility model, the front side of the sampling tube is provided with an anastomosis hole, and the inner cavity of the anastomosis hole is movably connected to an anastomosis plate. The front and rear sides of the anastomosis plate are fixedly connected to the movable shell. By setting the anastomosis hole and the anastomosis plate, when the sampling tube is detached from the soil, pulling the sampling tube upward can drive the anastomosis plate to squeeze the soil, which can facilitate the extrusion of the soil.

[0011] As a preferred embodiment of this utility model, a tension spring is fixedly connected to the top of the sampling tube, and the top of the tension spring is fixedly connected to the inner wall of the movable shell. A control rod is fixedly connected to the top of the sampling tube, and the top of the control rod passes through the movable shell and the T-shaped grip and extends to the inner cavity of the mating hole. By setting the tension spring and the control rod, when the sampling tube moves upward, the control rod can control the movement position of the sampling tube, while the tension spring can assist the sampling tube to return to its original position.

[0012] In a preferred embodiment of this invention, gripping plates are movably connected to opposite sides of the fixed plate. A pressing hole is provided on the front side of the gripping plate, and a pressing rod is movably connected to the inner cavity of the pressing hole. A connecting hole is provided on the right side of the control rod, and the front and rear sides of the pressing rod are fixedly connected to the connecting hole. By setting up the gripping plate, pressing hole, pressing rod, and connecting hole, when it is necessary to control the control rod to move up and down, the gripping plate is pressed down and rotates around the rotating rod. At this time, the inner wall of the pressing hole will press the pressing rod, and the pressing rod will descend, which will drive the control rod to descend.

[0013] As a preferred embodiment of this utility model, a rotating hole is provided on the front side of the grip plate, and a rotating rod is movably connected to the inner cavity of the rotating hole. The front and rear sides of the rotating rod are fixedly connected to the fixed plate, and a plug-in hole is provided on the front side of the rotating rod. By setting the rotating hole, the rotating rod and the plug-in hole, the rotating hole and the rotating rod can position the rotation position of the grip plate when it rotates, so that the grip plate will not move randomly.

[0014] In a preferred embodiment of this invention, the fixing component includes a movable plate movably connected to the inner cavity of the fixed shell. A pull rod is fixedly connected to the front side of the movable plate, the front side of the pull rod penetrates the fixed shell and extends to the outer side of the fixed shell, and a spring is sleeved on the surface of the pull rod. A plug-in block for use with a plug-in hole is fixedly connected to the rear side of the movable plate, the rear side of the plug-in block penetrates the fixed plate and extends to the inner cavity of the plug-in hole. By setting the fixing component, when the gripping plate drives the sampling tube to be inserted into the soil, the spring will undergo elastic deformation to drive the movable plate back to its original position. The movement of the movable plate will drive the plug-in block to be inserted into the plug-in hole, thus fixing the position of the gripping plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a combination of mating holes, a fixing plate, a fixing shell, and fixing components. The movement of the movable plate causes the insertion block to disengage from the insertion hole. Then, pulling up the gripping plate, accompanied by the tension of the tension spring, causes the sampling tube to return to the movable shell. At this point, the mating plate can squeeze out the soil. This solves the problem that in common manual soil samplers, after soil sampling, the soil sample is pushed out of the sampler by a pushing rod, which requires the user to press down hard with their palm, a process that is quite laborious.

[0023] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown, the present invention provides a soil sampling device for land engineering, including a movable shell 1, a sampling tube 2, a T-shaped handle 3, a mating hole 4, and two fixing plates 5. The sampling tube 2 is movably connected to the inner cavity of the movable shell 1. The top of the movable shell 1 is fixedly connected to the bottom of the T-shaped handle 3. The mating hole 4 is opened on the right side of the T-shaped handle 3. The right side of the T-shaped handle 3 is fixedly connected to the fixing plate 5.

[0025] The front side of the T-shaped grip bar 3 is movably connected to the fixed shell 6, and the rear side of the fixed shell 6 is fixedly connected to the fixed plate 5.

[0026] Fixing component 7 is disposed in the inner cavity of fixing shell 6.

[0027] refer to Figure 1 The surface of the movable shell 1 is fixedly connected with three grounding rods 8, and the surface of the grounding rods 8 is fixedly connected with a positioning plate 9.

[0028] The above solution is adopted: by setting up the grounding rod 8 and the positioning plate 9, when the movable shell 1 comes into contact with the ground, the grounding rod 8 is inserted into the ground, which can locate the position of the movable shell 1, while the positioning plate 9 can locate the position of the grounding rod 8.

[0029] refer to Figure 3 The sampling tube 2 has an anastomosis hole 10 on its front side. The anastomosis plate 11 is movably connected to the inner cavity of the anastomosis hole 10. The front and rear sides of the anastomosis plate 11 are fixedly connected to the movable shell 1.

[0030] Using the above scheme: by setting the anastomosis hole 10 and the anastomosis plate 11, after the sampling tube 2 is removed from the soil, pulling the sampling tube 2 upward will drive the anastomosis plate 11 to squeeze the soil, which can easily squeeze out the soil.

[0031] refer to Figure 3 A tension spring 12 is fixedly connected to the top of the sampling tube 2. The top of the tension spring 12 is fixedly connected to the inner wall of the movable shell 1. A control rod 13 is fixedly connected to the top of the sampling tube 2. The top of the control rod 13 passes through the movable shell 1 and the T-shaped grip 3 and extends to the inner cavity of the mating hole 4.

[0032] The above scheme is adopted: by setting up a tension spring 12 and a control rod 13, when the sampling tube 2 moves upward, the control rod 13 can control the movement position of the sampling tube 2, while the tension spring 12 can assist the sampling tube 2 to return to its original position.

[0033] refer to Figure 1 A gripping plate 14 is movably connected to one side of the fixed plate 5. A pressing hole 15 is provided on the front side of the gripping plate 14. A pressing rod 16 is movably connected to the inner cavity of the pressing hole 15. A connecting hole 17 is provided on the right side of the control rod 13. The front and rear sides of the pressing rod 16 are fixedly connected to the connecting hole 17.

[0034] The above solution is adopted: by setting up a grip plate 14, a pressing hole 15, a pressing rod 16 and a connecting hole 17, when it is necessary to control the control rod 13 to move up and down, the grip plate 14 is pressed down and rotates around the rotating rod 19. At this time, the inner wall of the pressing hole 15 will press the pressing rod 16, and the pressing rod 16 will descend, which will drive the control rod 13 to descend.

[0035] refer to Figure 3 and Figure 4A rotating hole 18 is provided on the front side of the grip plate 14. A rotating rod 19 is movably connected to the inner cavity of the rotating hole 18. The front and rear sides of the rotating rod 19 are fixedly connected to the fixing plate 5. A insertion hole 20 is provided on the front side of the rotating rod 19.

[0036] By adopting the above solution: by setting the rotating hole 18, the rotating rod 19 and the insertion hole 20, when the grip plate 14 rotates, the rotating hole 18 and the rotating rod 19 can position the rotation position of the grip plate 14, so that the grip plate 14 will not move randomly.

[0037] refer to Figure 4 The fixing component 7 includes a movable plate 71, which is movably connected to the inner cavity of the fixing shell 6. A pull rod 72 is fixedly connected to the front side of the movable plate 71. The front side of the pull rod 72 passes through the fixing shell 6 and extends to the outer side of the fixing shell 6. A spring 73 is sleeved on the surface of the pull rod 72. A plug block 74 that mates with the plug hole 20 is fixedly connected to the rear side of the movable plate 71. The rear side of the plug block 74 passes through the fixing plate 5 and extends into the inner cavity of the plug hole 20.

[0038] Using the above solution: By setting the fixing component 7, when the gripping plate 14 drives the sampling tube 2 to be inserted into the soil, the spring 73 will undergo elastic deformation to drive the movable plate 71 back to its original position. The movement of the movable plate 71 will drive the insertion block 74 to be inserted into the insertion hole 20, and at this time the position of the gripping plate 14 can be fixed.

[0039] The working principle of this utility model:

[0040] When in use, grip the T-shaped handle 3 and move the soil sampling device to the area where soil needs to be sampled. Then, press down the T-shaped handle 3 to drive the insertion rod 8 into the soil. When the positioning plate 9 contacts the ground, press down the handle 14 to rotate around the rotating rod 19. At this time, the inner wall of the squeezing hole 15 will squeeze the squeezing rod 16. The squeezing rod 16 will descend and drive the control rod 13 to descend. The descending control rod 13 will drive the sampling tube 2 into the soil and pull the tension spring 12. When the handle 14 rotates to the designated position, the spring 73 will undergo elastic deformation and drive the movable plate 71 back to its original position. The movement of the movable plate 71 will drive the insertion block 74 to be inserted into the insertion hole 20. At this time, the position of the handle 14 can be fixed. Then, pull up the T-shaped handle 3 to drive the sampling tube 2 out of the soil.

[0041] When soil needs to be removed, pull the lever 72 to move the movable plate 71. The movement of the movable plate 71 will cause the plug block 74 to disengage from the plug hole 20. Then, pull up the grip plate 14 and the tension of the tension spring 12 will cause the sampling tube 2 to return to the movable shell 1. At this time, the matching plate 11 can squeeze out the soil.

[0042] In summary, this soil sampling device for land engineering, through the coordinated use of mating holes 4, fixing plates 5, fixing shells 6, and fixing components 7, allows the movable plate 71 to move, causing the insertion block 74 to disengage from the insertion hole 20. Subsequently, pulling up the gripping plate 14, accompanied by the tension of the tension spring 12, causes the sampling tube 2 to return to the movable shell 1. At this point, the mating plate 11 can squeeze out the soil. This solves the problem of common manual soil samplers, where after soil sampling, the soil sample is pushed out of the sampler by a pushing rod, which requires the user to press down hard with their palm, a process that is quite laborious.
