Description

Technical Field

[0001] The utility model relates to the technical field of rock and soil exploration, in particular to a sand taking device used for rock and soil exploration. Background Art

[0002] Geotechnical engineering investigation refers to the activities of identifying, analyzing, and evaluating the geological, environmental characteristics and geotechnical conditions of the construction site and preparing investigation documents according to the requirements of the construction project.

[0003] At present, engineering construction has higher and higher requirements on the quality of geotechnical investigation. If the investigation work of the staff is not in place and the adverse engineering geological problems are not revealed, even if the design and construction of the upper structure have reached high quality, it will inevitably be damaged, which is very dangerous. A sand collector is needed in geotechnical investigation, but the sand collector currently used cannot seal the bottom of the sampling cavity during the sampling process, resulting in the sand and soil easily leaking out of the sampling cavity when sampling some loose sand and soil, thereby greatly reducing the collection efficiency. Therefore, in view of the above problems, a sand collector for geotechnical investigation is proposed. Utility Model Content

[0022] Embodiment

[0023] As Figures 1-5 shown, a sand sampling device for geotechnical investigation includes a collection box 1 and a sampling cylinder 7. The sampling cylinder 7 is fixedly connected to the outside of the collection box 1. One end of the collection box 1 is internally screwed with an end cover 2. An auger 12 is arranged inside the sampling cylinder 7. Discharge ports 19 are opened on both inner ends of the sampling cylinder 7. A rotating mechanism is arranged at the top end of the auger 12. A traveling mechanism is arranged on the outside of the collection box 1. The auger 12 is used to drill down the sandy soil, so that the sandy soil enters the inside of the collection box 1 through the discharge ports 19. The collection box 1 is used to centrally collect the sandy soil, thereby ensuring that the taken sandy soil will not be wasted and ensuring the efficiency of sand sampling.

[0024] As a further improvement of the present utility model, as Figure 2 and Figure 3 shown, the rotating mechanism includes a connecting plate 13 fixedly connected to the sampling cylinder 7. A second bearing 15 is fixedly connected to the outside of the connecting plate 13. A connecting ring 16 is fixedly connected to the outside of the second bearing 15. A motor 17 is fixedly connected to the inside of the connecting ring 16. A gear 18 is fixedly connected to the end of the main shaft of the motor 17. One end of the gear 18 meshes with a toothed ring 14, and the toothed ring 14 is fixedly connected to the connecting plate 13. A guiding component is arranged at one end of the connecting ring 16. Under the interaction of the gear 12 and the toothed ring 14, the connecting plate 13 can drive the auger 12 to rotate. The rotation of the auger 12 enables the sandy soil to gradually enter the inside of the collection box 1 through the sampling cylinder 7.

[0025] As a further improvement of the present utility model, as shown in Figure 2 , Figure 3 and Figure 5 The guiding assembly includes a connecting frame 11 fixedly connected to the connecting ring 16. A rolling ball 8 is rotatably connected to the inner side of the connecting frame 11. One end of the rolling ball 8 is slidably connected to a guiding column 9, and the guiding column 9 is fixedly connected to the sampling cylinder 7. Under the action of the connecting frame 11 and the rolling ball 8, it can be ensured that the connecting ring 16 does not rotate with the spiral drill rod 12 when the spiral drill rod 12 rotates.

[0026] As a further improvement of the present utility model, as shown in Figure 4 The bottom end of the guiding column 9 is fixedly connected with a second adjusting screw rod 10, and the second adjusting screw rod 10 is in threaded connection with the spiral drill rod 12. Under the action of the second adjusting screw rod 10, the spiral drill rod 12 can be drilled into the soil when the spiral drill rod 12 rotates.

[0027] As a further improvement of the present utility model, as shown in Figure 1 and Figure 2 The traveling mechanism includes a fixed frame 3 fixedly connected to the collection box 1. One end inside the fixed frame 3 is in threaded connection with a first adjusting screw rod 4. The bottom end outside of the first adjusting screw rod 4 is fixedly connected with a first bearing 5. The outside of the first bearing 5 is fixedly connected with a fixed frame 20. One end of the fixed frame 20 is rotatably connected with a wheel 6. The wheel 6 facilitates the movement of the device. When taking sand with the device, the wheel 6 is retracted into the inside of the fixed frame 3, so that the sampling cylinder 7 can be attached to the ground, thereby ensuring that the sandy soil taken out by the spiral drill rod 12 does not flow out from the gap between the sampling cylinder 7 and the ground.

[0028] Working process: When it is necessary to take sand through this device, the device can be pushed to a suitable position through the wheel 6. Then, the first adjusting screw rod 4 drives the wheel 6 to retract into the inside of the fixed frame 3 through the first bearing 5 and the fixed frame 20, so that the sampling cylinder 7 can be attached to the ground, thereby ensuring that the sandy soil taken out by the spiral drill rod 12 does not flow out from the gap between the sampling cylinder 7 and the ground. Then, the motor 17 drives the gear 18 to rotate, and the gear 18 drives the connecting disk 13 to rotate through the toothed ring 14. Then, the connecting disk 13 drives the spiral drill rod 12 to rotate. Sand is taken through the spiral drill rod 12. When the spiral drill rod 12 rotates, it will also rotate relative to the second adjusting screw rod 10, so that the spiral drill rod 12 will rotate and drill downward at the same time, causing the spiral drill rod 12 to gradually drill into the soil. At the same time, the spiral drill rod 12 will also drive the connecting frame 11 to slide downward along the guiding column 9 through the connecting disk 13, the connecting ring 16 and the rolling ball 8.

[0029] The above is the preferred embodiment of the present utility model. The basic principles, main features and advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the protection scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The protection scope claimed by the present utility model is defined by the appended claims and their equivalents.
