[0002] Engineering geological testing is an important preliminary work in construction projects, aimed at understanding and evaluating geological conditions such as foundation soil, rock and groundwater. Through this process, engineers can obtain data on the geological characteristics of the construction site, including soil bearing capacity, groundwater level, geological structure and other information. In order to determine whether foundation reinforcement is needed or to select a specific foundation form, such as pile foundation or raft foundation, soil sampling agencies for engineering geological testing are needed.

[0003] In traditional soil sampling mechanisms used in engineering geological testing, the sampling tube is firmly pushed into the soil layer to ensure a representative soil sample is obtained. During this advancement, the design of the sampling tube ensures that the soil is not excessively disturbed, preserving the sample's original state and structure. When the sampling tube reaches the predetermined depth, the internal interception device closes, preventing the soil sample from falling out of the tube or mixing with soil from other layers.

[0034] Specifically, when installing the drilling head 18 for drilling soil, first, by turning the handwheel 7, the worm 6 starts to rotate. The rotation of the worm 6 then drives the turbine 8 engaged therewith to rotate. As the turbine 8 rotates, the wheel 9 also rotates, and through the precise transmission of the connecting rod 10, the connecting column 11 is pulled inward, thereby shrinking the block 13 into the interior of the fixed seat 5. At this time, the operator firmly inserts the connecting block 16 at the top of the drilling head 18 into the interior of the fixed seat 5 to ensure alignment and firmness. Subsequently, by turning the handwheel 7 in the opposite direction, the block 13 is driven to reset. The block 13 is effectively supported under the tension of the first spring 15 and firmly embedded in the slot 17 of the connecting block 16, ensuring that the drilling head 18 is reliably locked in the fixed seat 5. Next, as the output end of the motor 4 is started, the fixed seat 5 starts to rotate, thereby driving the installed drilling head 18 to rotate synchronously and start the drilling operation. At the same time, the electric slide rail 2 is started, driving the connected sliding sleeve 3 to gradually move downward, thereby pushing the drilling head 18 to continuously penetrate the ground and perform soil drilling.

[0036] Specifically, when the drilling head 18 needs to be cleaned, first inject cleaning water into the water tank 20, and then start the water pump 23. The input end of the water pump 23 will extract the cleaning water in the water tank 20 and pump the cleaning water into the outlet pipe 24 through the output end of the water pump 23. The cleaning water then enters the annular water pipe 21 and is finally sprayed out from the evenly distributed nozzles 22, covering the outer wall of the drilling head 18. At the same time, the electric slide rail 2 is started, gradually driving the drilling head 18 to lift upward, so that the cleaning water is evenly sprayed on all surfaces of the drilling head 18 to ensure the cleaning effect. As the drilling head 18 rises, the bristles 28 installed inside the fixed platform 19 will work synchronously. The bristles 28 adhere to the outer wall of the drilling head 18 and mechanically clean its surface to further remove attached dirt and impurities.

[0037] Reference Figure 5 , a connecting block 16 is opened inside the fixed platform 19, a positioning block 29 is fixedly connected to the outer wall of the fixing ring 27, the positioning block 29 is slidably connected to the inside of the positioning groove 26, a connecting column 2 slidably connected to the inside of the fixed platform 19, one end of the connecting column 2 32 is rotatably connected to the buckle plate 31, and the other end of the connecting column 2 32 is fixedly connected to the locking block 30, the locking block 30 is slidably connected to the inside of the fixing ring 27, and a second spring 25 is sleeved on the outer wall of the connecting column 2 32, one end of the second spring 25 is fixedly connected to the inside of the fixed platform 19, and the other end of the second spring 25 is fixedly connected to one end of the locking block 30;

[0038] Specifically, when the bristles 28 on the drill head 18 need to be replaced, first bend the buckle plate 31 and adjust the buckle plate 31 and the connecting column 2 32 to a position in a straight line. At this time, the locking block 30 will be driven out of the fixing ring 27, thereby releasing the lock on the bristles 28. Next, insert the new bristles 28 into the fixing platform 19 to ensure that the bristles 28 are firmly fixed in the appropriate position through the fixing ring 27. At the same time, the positioning block 29 slides along the positioning groove 26 on the outer wall of the fixing ring 27 to ensure that the bristles 28 are accurately positioned in the fixing platform 19. Finally, rotate the buckle plate 31 and the connecting column 2 32 90°. The locking block 30 automatically resets under the tension of the second spring 25, tightly locking the fixing ring 27 in the fixing platform 19, ensuring that the new bristles 28 are firmly installed and ready for the next cleaning operation.

[0039] Working principle: When using the soil sampling mechanism for engineering geological detection, first drill the soil and install the drilling head 18, turn the handwheel 7 to drive the worm 6 to rotate, and the worm 6 drives the wheel disc 9 to rotate through the turbine 8, and then the wheel disc 9 drives the connecting column 11 through the connecting rod 10 to retract the block 13 into the fixed seat 5, and then insert the connecting block 16 on the top of the drilling head 18 into the fixed seat 5, and then reversely rotate the handwheel 7 to drive the block 13 to reset, and the block 13 is assisted by the tension of the first spring 15, and then the block 13 is embedded in the card slot 17 to lock the drilling head 18, and then the output end of the motor 4 drives the fixed seat 5 to rotate while driving the drilling head 18 to rotate, and at the same time, the electric slide rail 2 descends through the sliding sleeve 3 to drive the drilling head 18 to drill deep into the ground to drill the soil. When the drilling head 18 needs to be cleaned, cleaning water is injected into the water tank 20, and then the input end of the water pump 23 pumps the cleaning water in the water tank 20 The cleaning water is evenly sprayed on the outer wall of the drilling head 18 while the electric slide rail 2 drives the drilling head 18 to be lifted. At the same time, the brush 28 arranged in the fixed platform 19 cleans the outer wall of the drilling head 18. When the drilling head 18 needs to be replaced, it is only necessary to bend the buckle plate 31 so that the buckle plate 31 and the connecting column 2 32 are in a straight line. Then, the locking block 30 is driven to extend out of the fixing ring 27 to unlock the brush 28. Then, a new brush 28 is inserted into the fixing platform 19. The brush 28 is fixed by the fixing ring 27 and slid in the positioning groove 26 for positioning by the positioning block 29 on the outer wall. Then, the buckle plate 31 and the connecting column 2 32 are moved in a 90° direction, and then the locking block 30 is driven to reset by the tension of the second spring 25 to lock the fixing ring 27 in the fixing platform 19.
