[0002] The engineering geology drilling core sampling and extraction device is a professional equipment used in the field of engineering geology. It is mainly used to obtain rock cores after drilling into rock strata. Through a series of specific mechanical structures and operating processes, such as fixing devices, driving components to drive the drill bit operation, clever limiting and disassembly designs, etc., the rock core can be safely and accurately extracted from the borehole. It is an important device for providing reliable rock core samples for geological exploration, geological condition analysis in the early stage of engineering construction, and other work.
[0003] There is a problem with existing sampling devices. After sampling is completed, the design of the hollow drill bit connected to the drive component makes it difficult to remove the core from the hollow drill bit. If the core is forcibly knocked to extract the core, the vibration will be transmitted to the drive component through the drill bit. Long-term or frequent vibration can easily damage the parts of the drive component, thereby increasing maintenance costs and the risk of failure, thereby reducing work efficiency.

[0029] By setting the connecting mechanism, after sampling, if the core needs to be extracted, two limit rods two can be pulled outwards, which will drive the sliding blocks connected thereto to slide outwards along the plurality of round rods one. In the process of sliding of the two sliding blocks, the sliding blocks will extrude the springs on the plurality of round rods one, so as to accumulate energy for subsequent reset operation. With the outward movement of the two limit rods two, the restriction on the inner limit rod one of the rotating shaft can be removed, so that the limit rod one smoothly drives the hollow drill bit and the driving part to realize quick disassembly. When the hollow drill bit is disassembled alone, the rock core inside the hollow drill bit can be easily taken out by knocking. Through the setting, not only the cumbersome process of core sampling can be reduced, but also the work efficiency can be improved.
[0030] The configuration mechanism 3 comprises a bottom plate 31 arranged at the bottom of the sliding plate 1. The top of the bottom plate 31 is provided with a drill hole 32 matched with the hollow drill bit 25. The top of the bottom plate 31 is fixedly connected with an L-shaped rod 33. The top of the L-shaped rod 33 is fixedly connected with a motor two 34. The output shaft of the motor two 34 is fixedly connected with a screw rod 35 through a shaft coupling. The screw rod 35 penetrates through the L-shaped rod 33 and the sliding plate 1 and is in rotating connection with the L-shaped rod 33 and in threaded connection with the sliding plate 1. The top of the bottom plate 31 is fixedly connected with two round rods two 36. The two round rods two 36 penetrate through the sliding plate 1 and are in sliding connection with the sliding plate 1. The top ends of the two round rods two 36 are fixedly connected with the L-shaped rod 33. The bottom of the bottom plate 31 is rotatably connected with a plurality of moving wheels 37.

[0031] By setting the configuration mechanism, in use, first, the device can be moved to the specified core sampling site by means of the moving wheels at the bottom of the device. After reaching the specified site, the folding rods are pulled apart around, and after they are fully unfolded, the bolts are inserted into the limiting holes on the folding rods and the bottom plate to prevent the folding rods from moving. Then, the hydraulic cylinders on the folding rods are started simultaneously. At this time, the hydraulic cylinders will respectively push the supporting legs thereon to slowly move towards the ground until the four corners of the device are stably fixed. Through this setting, the adverse effects on the sampling work caused by the device falling during the sampling process can be effectively prevented.
[0032] A specific application of this embodiment is as follows: when in use, the device can first be moved to the designated core sampling location with the help of the moving wheels 37 at the bottom of the device. After arriving at the designated location, the folding rod 39 is pulled out in all directions. After it is fully unfolded, the pin 393 is inserted into the limiting hole 394 on the folding rod 39 and the bottom plate 31 to prevent the folding rod 39 from moving. Then, the hydraulic cylinder 391 on the folding rod 39 is started synchronously. At this time, the hydraulic cylinder 391 will push the support legs 392 thereon to move slowly toward the ground until the four corners of the device are firmly fixed. Through this arrangement, it is possible to effectively prevent the sampling work from being adversely affected by the tipping of the device during the sampling process; then, start the motor 1 21, and the motor 1 21 will drive the limiting rod 1 24 and the hollow drill bit 25 on the limiting rod 1 24 to rotate synchronously through the rotating shaft 22. At the same time, when the hollow drill bit 25 starts to rotate, the motor 2 34 can be started again. The motor 2 34 uses the screw 35 and the two The coordinated cooperation of the round rod 2 36 enables the slide plate 1 to drive the rotating hollow drill bit 25 to pass through the borehole 32, thereby carrying out sampling operations on the rock formation; after sampling, if it is necessary to extract the core, the two limit rods 29 can be pulled outward, and the two limit rods 29 will respectively drive the sliders 28 connected thereto to slide outward along the multiple round rods 1 27. During the sliding process of the two sliders 28, the sliders 28 will squeeze the springs 291 on the multiple round rods 1 27, so that the springs 291 accumulate energy to provide power for the subsequent resetting operation. As the two limit rods 29 move outward, the restrictive effect of the limit rod 1 24 in the rotating shaft 22 can be released, and the limit rod 1 24 can smoothly drive the hollow drill bit 25 and the driving component to be quickly disassembled. After the hollow drill bit 25 is removed separately, the core inside it can be easily removed by knocking. Through this arrangement, not only the tedious process of core sampling can be reduced, but also work efficiency can be improved.
