Description

Technical Field

[0001] This utility model relates to the field of geological drilling tools, and in particular to a thick-walled soil sampler that is easy to assemble. Background Technology

[0002] A thick-walled sampler is a tool used in geological exploration or geotechnical engineering to obtain undisturbed soil samples from boreholes for laboratory testing and analysis (such as physical and mechanical properties, permeability, etc.).

[0003] Existing thick-walled soil samplers, such as the one disclosed in utility model patent application number CN201720446042.7, include a conveniently assembled thick-walled soil sampler comprising a fixed joint, a waste soil tube, a sampling tube, and a tube shoe connected sequentially by threads. The sampling tube is composed of a first half-tube and a second half-tube, with the assembly planes between the first and second half-tubes connected by mortise and tenon joints. In this utility model, the two half-tubes can be pre-assembled via mortise and tenon joints, thereby fixing the assembly planes between the first and second half-tubes. The two assembly planes will not slip, thus facilitating the threaded connection of the two ends of the sampling tube. Assembly is very convenient, improving work efficiency and reducing labor intensity.

[0004] However, when using thick-walled soil samplers, the shoe and sampling tube are connected by threads. Due to work requirements, vibration or rotation is used when using thick-walled soil samplers. To prevent the shoe and sampling tube from falling off, the connection friction between the shoe and sampling tube is relatively large. However, when disassembling and assembling the shoe, chain clamps are required, which makes the disassembly and assembly of the shoe time-consuming and laborious. Most of the drilling time is wasted on disassembling and assembling the soil sampler, which affects work efficiency. Therefore, this application proposes a thick-walled soil sampler that is easy to assemble. Utility Model Content

[0005] The purpose of this invention is to address the problems in the prior art where threads are easily worn, and the disassembly and assembly of the tube shoe is time-consuming and laborious, affecting work efficiency, by proposing a thick-walled soil sampler that is easy to assemble.

[0006] The technical solution of this utility model is as follows: A thick-walled soil sampler that is easy to assemble includes a fixed joint, a sampling tube, and a tube shoe. A piston is slidably connected inside the fixed joint. Multiple insertion rods are fixedly connected to the bottom of the sampling tube, and the insertion rods have grooves. Multiple slots are opened on the top of the tube shoe. A first support ring is fixedly connected inside the tube shoe. A second support ring is fixedly connected inside the sampling tube. Multiple snap-fit ​​boxes are detachably installed on the first support ring. The multiple snap-fit ​​boxes are arranged in a circular array. Each snap-fit ​​box has a snap-fit ​​opening, which is connected to the slot. A snap-fit ​​mechanism is provided inside the snap-fit ​​box. A pressure rod is slidably connected to the snap-fit ​​box. The pressure rod is slidably connected to the second support ring. The pressure rod extends out to a fixed joint and is slidably connected to the fixed joint. A pressure ring is detachably installed at the end of each pressure rod away from the snap-fit ​​box.

[0014] Optionally, the top of the pressure rod is provided with a slot, and the bottom of the pressure ring is fixedly connected with multiple fixing blocks, which are arranged in a ring array, and the fixing blocks and the slot are slidably connected.

[0015] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0016] By inserting the rod into the slot, the spring causes the locking block to rebound, bringing the locking block into the groove through the bayonet to fix the sampling tube. This reduces operation time during installation, improves convenience, and increases work efficiency.

[0017] By pressing the pressure rod and sliding groove, the pressure rod drives the support frame to press down, and the connecting plate drives the locking block to move backward through the sliding groove, so that the locking block disengages from the groove and the locking slot, and the tube shoe can be disassembled, which reduces the operation time during disassembly and improves work efficiency.

[0018] This utility model discloses a thick-walled soil sampler that is easy to assemble. By using a pressure rod and a locking block, the tube shoe can be installed and removed, reducing the operation time when disassembling and installing the tube shoe onto the sampling tube, thus improving the convenience of use and the overall work efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figure 1 - Figure 3 As shown, this utility model discloses a thick-walled soil sampler that is easy to assemble, comprising a fixed connector 1, a sampling tube 2, and a tube shoe 3. A piston 101 is slidably connected inside the fixed connector 1. The top and bottom of the fixed connector 1 have threaded grooves. A threaded tube is fixedly connected to the top of the sampling tube 2, and the threaded tube and the threaded groove are threaded together. The threaded groove at the top of the fixed connector 1 is threadedly connected to a soil sampling drill. The fixed connector 1 and the tube shoe 3 are removed to extract the soil from the sampling tube 2. Multiple insertion rods 210 are fixedly connected to the bottom of the sampling tube 2, and grooves 211 are formed on the insertion rods 210. Multiple slots 310 are formed on the top of the tube shoe 3. A first support ring 4 is fixedly connected inside the tube shoe 3, and a second support ring 5 is fixedly connected inside the sampling tube 2. Anti-slip pads are fixedly connected to the inner walls of the first support ring 4 and the second support ring 5. A liner 6 is slidably connected inside the sampling tube 2, and the liner 6 fits against the inner walls of the first support ring 4 and the second support ring 5, allowing soil to be collected.

[0030] like Figure 1 - Figure 3 As shown, multiple snap-fit ​​boxes 7 are detachably installed on the support ring 4. The support ring 4 has threaded grooves. The snap-fit ​​boxes 7 are connected to the threaded grooves by bolts. The snap-fit ​​boxes 7 can be removed to clean and replace the internal parts to prevent the parts from aging, which would cause the snap-fit ​​to be insecure and the disassembly to be inconvenient.

[0031] Figure 1 , Figure 4 , Figure 6 As shown, a pressure rod 10 is slidably connected to the snap-fit ​​box 7. The pressure rod 10 has a pull-in hole, into which a pin 17 is inserted and pulled. The pull-in hole is located below the pressure ring 16. After the sampling tube 2 and the tube shoe 3 are fixedly connected, vibration and soil accumulation during soil sampling prevent the pressure rod 10 from pressing down, causing the snap-fit ​​block 12 to become unstable in connection with the groove 211, thus reducing the quality of soil sampling. The pressure rod 10 is slidably connected to the support ring 5. The pressure rod 10 extends to a fixed joint 1, which is slidably connected to the fixed joint 1. A pressure ring 16 is fixedly connected to one end of the multiple pressure rods 10 away from the snap-fit ​​box 7. A slot is opened at the top of the pressure rod 10, and a fixed block is fixedly connected to the bottom of the pressure ring 16. The fixed block and the slot are slidably connected. A snap-fit ​​slot 701 is opened on the snap-fit ​​box, which is connected to the slot 310. A snap-fit ​​mechanism is provided inside the snap-fit ​​box 7. The snap-fit ​​mechanism includes components fixedly connected to the bottom of the snap-fit ​​box 7. The spring 8 is fixedly connected to the support frame 9, which is a door frame shape. The second spring 11 is located inside the support frame 9, and there is a gap between the second spring 11 and the inner side of the support frame 9. The spring 8 is fixedly connected to the bottom center of the support frame. The support frame 9 is door frame shaped so that the force of the pressure rod 10 pressing down is evenly distributed on the spring 8. This prevents uneven tension when the locking block 12 is moved by the connecting plate 15, which would lead to unstable disassembly, increase disassembly time, and affect work efficiency.

[0032] like Figure 1 - Figure 6 As shown, a pressure rod 10 is fixedly connected to the support frame 9, and a spring 11 is fixedly connected inside the clip box 7. A clip 12 is fixedly connected to the spring 11. The clip box 7 is equipped with a moving mechanism to limit the movement of the clip 12. The moving mechanism includes two sliding grooves 13 fixedly connected inside the machine housing. A clip 701 is located between the two sliding grooves 13. A guide rod 14 is fixedly connected inside the groove of the sliding groove 13. The guide rod 14 is slidably connected to the clip 12. One end of a connecting plate 15 is hinged to the support frame 9, and the other end of the connecting plate 15 is hinged to the clip 12. By pressing down the support frame 9 with the pressure rod 10, the connecting plate 15 is moved to move the clip. At the same time, the guide rod 14 in the sliding groove 13 limits the movement of the clip 12 to prevent the clip 12 from failing to position, resulting in unstable fixing and causing the tube shoe 3 to detach from the sampling tube 2, leading to soil sampling failure. By pressing the pressure rod 10, the support frame 9 is lowered, causing the clip 12 to move and fix the insertion rod 210.

[0033] In this embodiment, firstly, the insertion rod 210 of the sampling tube 2 is aligned with the slot 310 on the tube shoe 3. The insertion rod 210 is inserted into the slot 310, and the insertion rod 210 touches the locking block 12. The spring 11 is stressed, causing the locking block 12 to retract. The guide rod 14 in the sliding groove 13 limits and positions it. Then, the spring 11 rebounds, and the locking block 12 is inserted into the groove of the insertion rod 210 through the bayonet 701 to fix the tube shoe 3. Then, the liner 6 is inserted into the sampling tube 2, and the fixing joint 1 is rotated to make it threadedly connected to the sampling tube 2. Pin 17 is inserted into the insertion hole on the pressure rod 10 to fix the pressure rod 10. Then, the fixing joint 1 is threaded onto the soil sampling drill to start collecting soil. After collection, the fixing joint 1 is removed from the soil sampling drill, the pin 17 is pulled out, the pressure ring 16 is installed on the pressure rod, and the pressure ring 16 is pressed. The pressure rod 10 drives the support frame 9 to sink, and the connecting plate 15 drives the locking block 12 to move. The locking block 12 is pulled out of the insertion rod 210, the tube shoe 3 is removed, the pressure ring 16 is removed, and then the liner 6 is taken out to collect the collected soil. The installation and removal of the tube shoe 3 through the pressure rod 10 and the locking block 12 reduces the operation time when disassembling and installing the tube shoe 3 on the sampling tube 2, improving the convenience of use and the overall work efficiency.

[0034] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
