Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology for water conservancy experimental testing, specifically a soil sampling device for water conservancy experimental testing. Background Technology

[0002] In the geological exploration and investigation work of water conservancy and hydropower projects, in order to obtain the physical and mechanical properties of foundation soil, in addition to in-situ testing, the main method is to drill and extract soil for indoor geotechnical testing. This facilitates the detection of various data from the extracted soil samples. However, in the process of use, the soil sampling device has many parts, making it difficult to carry different drill bits. Furthermore, the soil sampler requires workers to apply force to it during use, making it quite laborious. Utility Model Content

[0003] The purpose of this utility model is to provide a soil sampling device for hydraulic experimental testing, so as to solve the problem mentioned in the background art that it is inconvenient to sample when applying force to the soil sampling device.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a soil sampling device for hydraulic experimental testing, comprising a flat plate frame, a handrail fixedly installed on one side surface of the flat plate frame, and a parts storage box placed on the side of the flat plate frame near the handrail, a drill motor module arranged above the flat plate frame, and a side support slidably installed on the outer surface of the flat plate frame.

[0005] Preferably, a threaded sliding mechanism is provided between the side support and the drill motor module. The threaded sliding mechanism includes: a moving platform, on the outer surface of which the drill motor module is fixedly mounted, and the output end of the drill motor module passes through the outer surface of the moving platform; a sliding guide rail assembly is fixedly mounted on the outer surface of the side support, and the outer surface of the sliding guide rail assembly is fixedly connected to the moving platform; a worm motor is fixedly mounted on one side surface of the side support; a worm wheel screw is rotatably mounted on the outer surface of the side support, and the worm wheel screw meshes with the output end of the worm motor; the worm wheel screw is threadedly connected to the moving platform; and a drill rod is fixedly mounted on the output end of the drill motor module, and the drill rod passes through the plate frame.

[0006] By adopting the above technical solution, the rotation of the worm motor can drive the worm wheel screw to rotate, which in turn can drive the moving platform to move vertically up and down along the direction of the sliding guide rail assembly. This allows the drill bit motor module and drill rod to move vertically to drill and extract soil from the ground. Furthermore, the self-locking property of the worm motor and worm wheel screw allows the drill bit motor module to descend stably without requiring workers to apply force to the soil extraction device, greatly improving the efficiency of drilling and soil extraction.

[0007] Preferably, the outer surface of the flat plate is threaded with screws, and the screws on the outer surface of the flat plate engage with the outer surface of the side support. The side support has a triangular design and a handle is provided on its outer surface.

[0008] By adopting the above technical solution, the side support can be easily fixedly installed on the outer surface of the flat plate frame. The triangular design of the side support allows it to withstand more force and reduce weight, and it is easy to assemble and disassemble by gripping the handle.

[0009] Preferably, a caster wheel is rotatably mounted on the outer surface of the end of the flat plate frame away from the side support, and the caster wheel is located around the perimeter of the flat plate frame.

[0010] By adopting the above technical solution, the flatbed frame can be easily moved by the casters, which facilitates the movement of the soil extraction device and the transportation of parts.

[0011] Preferably, the outer surface of the flat plate frame is provided with a plug-in opening mechanism, which allows the flat plate frame to be fixed to the ground, reducing the upward force when the soil sampling device drills into the soil, and preventing the flat plate frame from rotating due to being lifted by the drill bit motor module during soil drilling.

[0012] By adopting the above technical solution, when drilling downwards and taking soil, the flat plate frame will not be lifted up by the force of drilling downwards, and the flat plate frame will not rotate due to the drilling rod getting stuck, thus reducing the danger during use.

[0013] Preferably, the insertion and opening mechanism includes: a locking rod, which is inserted and installed on the outer surface of the plate frame, and the plate frame and the locking rod are engaged; an opening piece is rotatably installed on the outer surface of the locking rod, and a wedge-shaped protrusion is provided at the end of the opening piece away from the plate frame; a shear screw is installed through the outer surface of the locking rod, and the shear screw and the locking rod are slidably connected; the outer surface of the shear screw is in contact with the outer surface of the opening piece; the shear screw penetrates the outer surface of the plate frame, and the plate frame and the shear screw are slidably connected; a fastening nut is threaded on the outer surface of the shear screw, and the outer surface of the fastening nut is in contact with the outer surface of the plate frame.

[0014] Using the above technical solution, after inserting the opening plate and the sheathing screw into the drilled hole, the flat plate frame can be pushed into place above the opening plate. Then, the locking rod can be lifted and inserted into the outer surface of the flat plate frame, and the fastening nut can be screwed into the sheathing screw and tightened. Through the tightening of the sheathing screw and the fastening nut, the sheathing screw can rise and move, allowing the sheathing screw to expand the opening plate as it moves, so that the wedge-shaped protrusion of the opening plate can be engaged with the inner wall of the hole, allowing the flat plate frame to be fixed to the ground.

[0015] Preferably, the output end of the drill motor module is fixedly installed with an intermediate connecting rod, and the outer surface of the intermediate connecting rod is provided with an elastic pushing mechanism. The elastic pushing mechanism enables the soil sampling device to accurately obtain soil from different soil layers without mixing the soil together.

[0016] By adopting the above technical solution, soil samples at different depths can be accurately collected, preventing soil samples from different depths from mixing together.

[0017] Preferably, the elastic pushing mechanism includes: a top rod, which is fixedly installed at one end of an intermediate connecting rod, and movable tension rods are slidably installed inside the intermediate connecting rod and the top rod, the movable tension rods being in contact with each other and having a concentric design; an elastic insert rod is slidably installed on the outer surface of the top rod, and one end of the elastic insert rod is in contact with the outer surface of the movable tension rod; spring collecting boxes are slidably installed on both sides of the outer surfaces of the intermediate connecting rod and the top rod; and pushing balls are slidably installed on the outer surfaces of the intermediate connecting rod and the top rod, the pushing balls engaging with the intermediate connecting rod and the top rod respectively, the pushing balls being in contact with the outer surface of the movable tension rod, and the pushing balls being in contact with the outer surface of the spring collecting box.

[0018] Using the above technical solution, the intermediate connecting rod can be connected, allowing it and the top rod to be extended for easy insertion into holes of different depths. When the drill motor module moves down, the elastic insert will contact the bottom of the hole, allowing it to retract into the intermediate connecting rod. This pushes the moving tension rod and the pushing ball into the intermediate connecting rod and the top rod, ejecting the spring collection boxes on both sides of the intermediate connecting rod and the top rod. The spring collection boxes can then be inserted into the inner wall of the hole, and as the drill motor module rotates, soil is shoveled into the spring collection boxes. Subsequently, as the drill motor module rises, the elastic insert will disengage from the bottom of the hole, automatically resetting. At the same time, the tension rod descends under its own weight, resetting the pushing ball and the spring collection box. Then, the intermediate connecting rod and the top rod can be disassembled and removed one by one, facilitating soil sampling from different soil layers.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the soil sampling device for hydraulic experimental testing:

[0020] 1. After pushing the flat plate to the sampling point and fixing it, the worm motor can be started to drive the worm wheel screw to rotate, so that the worm wheel screw can drive the moving platform to move. The moving platform can move vertically up and down along the direction of the sliding guide rail assembly. The up and down movement of the moving platform can cause the drill bit motor module to move up and down along with it, so that the drill rod can drill into the soil as the drill bit motor module is started. Through the self-locking property of the worm wheel screw and the sliding guide rail assembly, the drill bit motor module can descend stably without the need for workers to apply force to the soil sampling device, which improves the efficiency and convenience of soil sampling.

[0021] 2. Drill the corresponding shallow hole at the location where sampling is required. Then, insert the opening plate and the shear screw into the hole. Next, push the plate frame above the opening plate and insert the locking rod and the shear screw into the outer surface of the plate frame so that the locking rod can engage with the plate frame. Then, screw the fixing nut into the shear screw and tighten it so that the shear screw can move upward and push open the opening plate. The wedge-shaped protrusion on the outer surface of the opening plate can engage with the inner wall of the hole, allowing the opening plate to open and be locked inside the hole. This allows the plate frame to be fixed to the ground, preventing the plate frame from being pushed up and rotated due to the descent and extension of the drill bit motor module and drill rod when the device is sampling soil. This reduces the danger of soil sampling and allows the drill rod to drill and sample soil more quickly.

[0022] 3. When soil sampling is required after the initial soil extraction, simply detach the drill rod from the drill motor module and connect the top rod to the intermediate connecting rod. Then, extend the intermediate connecting rod according to the depth of the hole, and finally connect the intermediate connecting rod to the drill motor module. The drill motor module can then be lowered and rotated, allowing the elastic insertion rod to descend and contact the bottom of the hole. The elastic insertion rod retracts into the top rod, and the movement of the elastic insertion rod drives the moving tension rod, which in turn pushes the ball bearings, causing the spring collection box to move. The spring collection box extends from the intermediate connecting rod and the top rod. Combined with the rotation of the drill motor module and the intermediate connecting rod and the top rod, the spring collection box inserted into the soil rotates and collects the soil, facilitating sampling at different depths and preventing soil from mixing during sampling.

[0031] 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.

[0032] Please see Figure 1-7 This utility model provides a technical solution: a soil sampling device for water conservancy experimental testing, including a flat plate frame 1, a handrail fixedly installed on one side surface of the flat plate frame 1, and a parts storage box 3 placed on the side of the flat plate frame 1 near the handrail, and a drill bit motor module 9 arranged above the flat plate frame 1.

[0033] The handrails provide a convenient grip, allowing for easy control of the movement direction of the flat plate frame 1. Meanwhile, the parts storage box 3 provides convenient storage for drill bits and parts of different specifications.

[0034] A side support 4 is slidably mounted on the outer surface of the flat plate frame 1, and a threaded sliding mechanism is provided between the side support 4 and the drill motor module 9. The threaded sliding mechanism includes: a moving platform 8, on the outer surface of the moving platform 8 the drill motor module 9 is fixedly mounted, and the output end of the drill motor module 9 passes through the outer surface of the moving platform 8; a sliding guide rail assembly 7 is fixedly mounted on the outer surface of the side support 4, and the outer surface of the sliding guide rail assembly 7 is fixedly connected to the moving platform 8; a worm motor 5 is fixedly mounted on one side surface of the side support 4; a worm wheel screw 6 is rotatably mounted on the outer surface of the side support 4, and the worm wheel screw 6 meshes with the output end of the worm motor 5; the worm wheel screw 6 is threadedly connected to the moving platform 8; and a drill rod 10 is fixedly mounted on the output end of the drill motor module 9, and the drill rod 10 passes through the flat plate frame 1.

[0035] When soil sampling is required, simply push the flat plate frame 1 to the sampling location and fix it in place. Then, start the drill bit motor module 9 and the worm motor 5. The drill bit motor module 9 will drive the drill rod 10 to rotate and drill a hole to extract soil. As the worm motor 5 rotates, the worm wheel screw 6 will drive the moving platform 8 to move. The moving platform 8 will move the drill bit motor module 9 up and down along the direction of the sliding guide rail assembly 7, allowing the drill bit motor module 9 to descend stably and slowly. This allows workers to easily drill and extract soil without applying force to the device, saving workers' strength and improving the efficiency and convenience of drilling and soil extraction.

[0036] The outer surface of the flat plate frame 1 is threaded with screws, and the screws on the outer surface of the flat plate frame 1 engage with the outer surface of the side support 4. The side support 4 has a triangular design and a handle is provided on the outer surface of the side support 4.

[0037] The side support 4 can be fixedly installed on the outer surface of the flat plate frame 1 by screws. When it is necessary to remove the side support 4 for disassembly and maintenance of the parts, the side support 4 can be removed by simply using the handle. The triangular design of the side support 4 improves the stability of the drill motor module 9 during use.

[0038] A caster wheel 2 is rotatably mounted on the outer surface of the end of the flat plate frame 1 away from the side support 4, and the caster wheel 2 is located around the flat plate frame 1.

[0039] The casters 2 allow the flat rack 1 to be moved easily and facilitate the transport of the parts storage box 3.

[0040] The outer surface of the flat plate frame 1 is provided with a plug-in opening mechanism. This mechanism allows the flat plate frame 1 to be fixed to the ground, reducing the upward force exerted by the soil sampling device during drilling and preventing the flat plate frame 1 from rotating due to being lifted by the drill bit motor module 9. The plug-in opening mechanism includes: a locking rod 11, which is plugged into and installed on the outer surface of the flat plate frame 1, engaging with the flat plate frame 1. An opening plate 12 is rotatably mounted on the outer surface of the locking rod 11. A wedge-shaped protrusion is provided at the end away from the plate frame 1. A shear screw 13 is installed through the outer surface of the clamping rod 11, and the shear screw 13 is slidably connected to the clamping rod 11. The outer surface of the shear screw 13 is in contact with the outer surface of the opening plate 12. The shear screw 13 penetrates the outer surface of the plate frame 1, and the plate frame 1 and the shear screw 13 are slidably connected. A fastening nut 14 is threaded on the outer surface of the shear screw 13, and the outer surface of the fastening nut 14 is in contact with the outer surface of the plate frame 1.

[0041] When soil needs to be removed, corresponding holes need to be drilled according to the installation position of the clamping rod 11. Then, the opening plate 12 and the shear screw 13 can be inserted into the holes. Then, the plate frame 1 can be pushed above the clamping rod 11. Then, the clamping rod 11 and the shear screw 13 can be inserted into the interior of the plate frame 1. Then, the fastening nut 14 can be screwed into the interior of the shear screw 13, so that the shear screw 13 can move as the fastening nut 14 is tightened. The shear screw 13 can open the opening plate 12 as it moves, so that the wedge-shaped protrusion on the outer surface of the opening plate 12 can be locked into the hole, so that the plate frame 1 can be fixed to the ground. This provides the plate frame 1 with a gripping force, so that when the drill bit motor module 9 and drill rod 10 are subjected to force and descend, the plate frame 1 will not rotate due to the drill rod 10 getting stuck, thus improving the safety during use.

[0042] A middle connecting rod 15 is fixedly installed at the output end of the drill bit motor module 9, and an elastic pushing mechanism is provided on the outer surface of the middle connecting rod 15. This elastic pushing mechanism allows the soil sampling device to accurately obtain soil from different soil layers without mixing the soil together. The elastic pushing mechanism includes a top rod 17, which is fixedly installed at one end of the middle connecting rod 15. Moving tension rods 16 are slidably installed inside both the middle connecting rod 15 and the top rod 17. The moving tension rods 16 are in contact with each other and are concentrically designed. An elastic insert rod 18 is slidably mounted on the outer surface of rod 17, and one end of the elastic insert rod 18 is in contact with the outer surface of the movable tension rod 16. Spring collection boxes 19 are slidably mounted on the outer surfaces of the intermediate connecting rod 15 and the top rod 17, respectively. Pushing balls 20 are slidably mounted on the outer surfaces of the intermediate connecting rod 15 and the top rod 17, respectively, and the pushing balls 20 are engaged with the intermediate connecting rod 15 and the top rod 17, respectively. The pushing balls 20 are in contact with the outer surface of the movable tension rod 16 and the outer surface of the spring collection box 19.

[0043] When soil sampling is required for different soil layers, simply raise the moving platform 8 and drill motor module 9, remove the drill rods 10 from the drill motor module 9 and disassemble them one by one. Then, assemble the intermediate connecting rod 15 and the top rod 17, and extend and connect the intermediate connecting rod 15 according to the depth of the soil sampling hole. After that, connect and fix the intermediate connecting rod 15 to the drill motor module 9. Then, the drill motor module 9 can be lowered so that the elastic insertion rod 18 can contact the bottom of the hole and retract into the top rod 17. This allows the elastic insertion rod 18 to push the movable tension rod 16, which in turn pushes the moving ball bearing 20 to move. The moving ball bearing 20 can then push the spring collection box 19 out from between the intermediate connecting rod 15 and the top rod 17, allowing the spring collection box 19 to be inserted. The soil is shoveled into the inner wall of the hole as the drill motor module 9 rotates. Then, the drill motor module 9 can be raised to reset the elastic rod 18 and the movable tension rod 16 can be reset by gravity. After the movable tension rod 16 is reset, the spring collection box 19 retracts and drives the push ball 20 to reset, so that the spring collection box 19 can retract with the soil into the intermediate connecting rod 15 and the top rod 17. Then, the intermediate connecting rod 15 and the top rod 17 can be removed one by one. Then, the spring collection box 19 can be pushed out by inverting the intermediate connecting rod 15, and the soil can be taken out from the spring collection box 19. This facilitates accurate sampling of soil at different depths and prevents soil samples from different depths from mixing together, which would affect subsequent testing.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
