Description

Technical Field

[0001] This utility model relates to the field of engineering survey, and in particular to an underground sample collection device for engineering survey. Background Technology

[0002] Engineering survey refers to the process of conducting detailed investigations and technical assessments of the proposed site and its surrounding environment before the planning, design, and construction of an engineering project. Its purpose is to obtain accurate geological, hydrological, and topographical information to provide a scientific basis for subsequent design and construction, and to ensure the safety, stability, and economic rationality of the project. In the field of engineering survey, the collection of underground samples is an important means of assessing key information such as geological structure, soil composition, and groundwater conditions.

[0003] Current engineering survey sampling typically involves using a geological exploration drilling rig to drive a drill rod into the ground to collect samples, which are then extracted from the drill rod. However, the drill rod and drill bit on current equipment are usually fixed in design. When the drill bit needs to be replaced due to wear or damage, the entire sampling equipment must be stopped, and a cumbersome disassembly and reinstallation process must be carried out. This not only increases maintenance costs but also seriously affects work efficiency and safety, making it quite inconvenient to use.

[0004] Therefore, it is necessary to design an underground sample collection device for engineering exploration that can install and disassemble drill bits for sampling, is simple to operate, facilitates drill bit replacement and loading / unloading, reduces maintenance costs, shortens replacement time, and improves safety and convenience of use. Utility Model Content

[0005] To overcome the drawbacks of requiring the entire sampling equipment to be stopped and a cumbersome disassembly and reinstallation process to replace drill bits due to wear or damage, which not only increases maintenance costs but also seriously affects work efficiency and safety and is inconvenient to use, this utility model provides an underground sample collection device for engineering exploration that can install and disassemble drill bits for sampling, is simple to operate, facilitates drill bit replacement and loading / unloading, reduces maintenance costs, shortens replacement time, and improves the safety and convenience of use.

The adjustment platform is connected to the upper right side of the mobile vehicle, and the rotating shaft is rotatably connected to the adjustment platform. The drill bit is detachably connected to the right side of the rotating shaft. The fixing component is provided on the rotating shaft for fixing the drill bit. A sampling component for collecting underground samples is provided between the rotating shaft and the drill bit. A protective component is provided on the outer right side of the rotating shaft for protecting the connection between the sampling component and the rotating shaft.

[0007] As a preferred technical solution of this utility model, the drill bit has teeth on the right side.

[0008] As a preferred technical solution of this utility model, the fixing component includes a mounting frame, a limiting frame, a first telescopic spring, an electric push rod, and a pressing frame. The mounting frame is connected to the inner side of the right side of the rotating shaft. The limiting frame is slidably connected to both the front and rear sides of the mounting frame. The limiting frame is connected to the mounting frame by two left and right first telescopic springs. The electric push rod is connected to the inner side of the left side of the rotating shaft. The pressing frame is connected to the telescopic end of the electric push rod. The limiting frame is in contact with the pressing frame and is engaged with the drill bit.

[0009] As a preferred technical solution of this utility model, the sampling assembly includes a sampling frame, a connecting block, a sleeve, a limiting rod, and a second telescopic spring. Two connecting blocks are snapped onto the drill bit, and sampling frames are connected to each connecting block. The sampling frames are in contact with the drill bit and with each other. Sleeves are connected to the front and rear sides of the right side of the rotating shaft. A limiting rod is slidably connected to each sleeve. The limiting rods are snapped onto the connecting blocks on the same side, and a second telescopic spring is connected between the limiting rods and the sleeves on the same side.

[0010] As a preferred technical solution of this utility model, the sampling frames are all arc-shaped.

[0011] As a preferred technical solution of this utility model, the protective component includes a protective cover and a third telescopic spring. The protective cover is slidably connected to the outer side of the right side of the rotating shaft, and the third telescopic spring is connected between the protective cover and the rotating shaft.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model uses a drill bit and a sampling frame to drill into the ground for sampling. When used for a long time, the squeezing frame can be moved to detach from the limiting frame, and the limiting frame can be moved in the opposite direction to reset and detach from the drill bit. Then the drill bit can be removed and replaced, and a new one can be installed for use. This allows for the installation and removal of the drill bit for sampling. The operation is simple, and it is convenient to replace and remove the drill bit, reducing maintenance costs, reducing replacement time, and improving the safety and convenience of use.

[0013] 2. This utility model adjusts the angle of the rotating shaft by adjusting the platform and controls the movement and rotation of the rotating shaft, so that the drill bit and sampling frame drill into the ground to collect samples. Then, the protective cover is pulled to move, and the limiting frame is pressed by hand to move and disengage from the connecting block. Then, the sampling frame is pulled to move and remove the sample. The sample can then be taken out, thus enabling the installation and disassembly of the sampling frame for sampling, facilitating sample removal, saving manpower and time, and improving sampling efficiency.

[0014] 3. During the sampling process, this utility model protects the connection between the connecting block and the rotating shaft with a protective cover, thereby protecting the connection between the connecting block and the rotating shaft during sampling, preventing the sampling frame from loosening or slipping and affecting the sampling, improving the stability of use, and further improving the sampling efficiency.

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] An underground sample collection device for engineering survey, such as Figures 1-5As shown, the device includes a mobile vehicle 1, an adjusting platform 2, a rotating shaft 3, a drill bit 4, a fixing assembly, a sampling assembly, and a protective assembly. The adjusting platform 2 is connected to the upper right side of the mobile vehicle 1. The rotating shaft 3 is rotatably connected to the adjusting platform 2. The drill bit 4 is detachably connected to the right side of the rotating shaft 3. The drill bit 4 has teeth on its right side for easy insertion into the ground. The rotating shaft 3 is equipped with a fixing assembly for fixing the drill bit 4. The fixing assembly includes a mounting bracket 5, a limiting bracket 6, a first telescopic spring 7, and an electric actuator 8. The rotating shaft 3 is connected to the inner right side of the extrusion frame 9, and the mounting frame 5 is connected to the inner right side of the rotating shaft 3. The mounting frame 5 is slidably connected to the front and rear sides of the mounting frame 5. Two first telescopic springs 7 are connected to the mounting frame 5 on the left and right sides of the limiting frame 6. The electric actuator 8 is connected to the inner left side of the rotating shaft 3, and the extrusion frame 9 is connected to the telescopic end of the electric actuator 8. The limiting frames 6 are in contact with the extrusion frame 9 and are engaged with the drill bit 4. A space for extruding underground samples is provided between the rotating shaft 3 and the drill bit 4. The sampling assembly includes a sampling frame 10, connecting blocks 11, sleeves 12, a limiting rod 13, and a second telescopic spring 14. Two connecting blocks 11 are engaged with the drill bit 4, and each connecting block 11 is connected to a sampling frame 10. The sampling frames 10 are in contact with the drill bit 4 and are mutually contacting each other. All sampling frames 10 are arc-shaped to conform to the shape of the drill bit 4. Sleeves 12 are connected to both the front and rear sides of the right side of the rotating shaft 3, and each sleeve 12 has a sliding connection. The limiting rod 13 is connected to the connecting block 11 on the same side. The limiting rod 13 is connected to the sleeve 12 on the same side by the second telescopic spring 14. The outer right side of the rotating shaft 3 is provided with a protective component for protecting the connection between the sampling component and the rotating shaft 3. The protective component includes a protective cover 15 and a third telescopic spring 16. The protective cover 15 is slidably connected to the outer right side of the rotating shaft 3. The third telescopic spring 16 is connected between the protective cover 15 and the rotating shaft 3.

[0023] When engineering surveys require the collection of underground samples, this device can be used. The mobile vehicle 1 moves the device to the designated area, and then the sampling frame 10 is inserted into the drill bit 4. The sampling frames 10 are all arc-shaped to easily fit the shape of the drill bit 4, allowing the connecting block 11 to engage with the drill bit 4. The drill bit 4 has teeth on its right side for easy insertion into the ground. Next, the drill bit 4 is engaged with the rotating shaft 3, causing the connecting block 11 to contact the limiting rod 13. The limiting rod 13 moves along the sleeve 12 and then returns to its original position. The second telescopic spring 14 is compressed and then rebounds, securing the limiting rod 13 with the connecting block 11. Then, the electric actuator 8 is activated, and the electric actuator... Rod 8 drives the extrusion frame 9 to move, causing the limiting frame 6 to move outward along the mounting frame 5 and engage with the drill bit 4. The first telescopic spring 7 is stretched, thereby fixing the drill bit 4 in place. After installation, according to the survey location, the angle of the rotating shaft 3 is adjusted by the adjusting platform 2, and the movement and rotation of the rotating shaft 3 are controlled, so that the drill bit 4 and the sampling frame 10 contact the ground and drill into the ground for sampling, allowing the sample to enter the sampling frame 10. Then, the angle of the rotating shaft 3 is adjusted by the adjusting platform 2, and the rotating shaft 3 is controlled to move and rotate in the opposite direction, so that the drill bit 4 and the sampling frame 10 are disengaged from the ground. Subsequently, the protective cover 15 is pulled to move, and the third telescopic spring 16... The sample frame 10 is then moved and removed by pressing the limiting frame 6 with your hand. The sample frame 10 is then pulled to remove the sample. The sampling frame 10 is then separated, and the sample is removed. This allows for the installation and removal of the sampling frame 10 for sampling, facilitating sample removal, saving manpower and time, and improving sampling efficiency. The above operation is then repeated to install the sampling frame 10, and the device is moved to the next survey location for sampling. When the drill bit 4 is damaged after prolonged use, the electric actuator 8 can be reversed to move the squeezing frame 9 in the opposite direction and disengage it from the limiting frame 6. The first telescopic spring 7 returns, and the limiting frame 6 moves in the opposite direction to reset and disengage from the drill bit 4. Then... The drill bit 4 is removed and replaced. The new drill bit 4 is then snapped into the rotating shaft 3. The above operation is repeated to install and fix the drill bit 4, thereby enabling the installation and removal of the drill bit 4 for sampling. The operation is simple, facilitating the replacement and disassembly of the drill bit 4, reducing maintenance costs, shortening replacement time, and improving the safety and convenience of use. During the sampling process, the protective cover 15 protects the connection between the connecting block 11 and the rotating shaft 3, preventing the sampling frame 10 from loosening or slipping and affecting the sampling, thus improving the stability of use and further improving the sampling efficiency. Subsequently, the device can be moved away by the operation of the mobile cart 1.
