Description

TECHNICAL FIELD

[0002] Rock-soil is a general term for any kind of rock and soil constituting the earth's crust from the perspective of engineering construction, and can be divided into five categories of hard (hard rock), less hard (soft rock), weakly connected, loose and unconnected, and having special composition, structure, state and properties. When rock (bedrock) is used as the basic bearing layer, it is usually necessary to collect a certain amount of rock samples for determination and testing of the main physical properties and mechanical properties of the rock. Generally, slightly weathered or slightly weathered rock is used as a sample.

DETAILED DESCRIPTION

[0029] Please refer to Figures 1-6The embodiments of the present invention will be further described below;

[0030] A soil and rock sampling device includes a main cylinder 1, a brake seat 2, and a sampling box 3. The brake seat 2 is located at the upper end of the main cylinder 1, and the sampling box 3 is located at the upper end of the brake seat 2.

[0031] The main cylinder 1 includes a collection cylinder 9, an outer cylinder 14, and an inner cylinder 15. The collection cylinder 9, the outer cylinder 14, and the inner cylinder 15 are layered from the outside to the inside. The cylinder structure serves as the soil drilling and collection end of the collection device.

[0032] The brake seat 2 includes a bearing disc 11 and a connecting pipe 12. The upper and lower ends of the bearing disc 11 are respectively provided with an outer gear disc 20 and an inner gear disc 17 as the transmission end, which serve as the transmission structure of the soil drilling and collection end of the collection device.

[0033] A drill disk 4 is installed at the bottom of the main cylinder 1. Several anchor bolts 7 are arranged in a ring on the upper surface of the drill disk 4, and the upper ends of the anchor bolts 7 are connected to the upper end of the main cylinder 1. Figure 1 As shown, the acquisition device uses the drilling disc 4 to place and fix the main cylinder 1, and uses the anchor bolts 7 to laterally stabilize the upper and lower ends of the drilling disc 4 and the main cylinder 1.

[0034] Both the outer cylinder 14 and the inner cylinder 15 are spiral metal cylinders. The outer surfaces of both the outer cylinder 14 and the inner cylinder 15 are integrally formed drilling threads. The upper end of the outer cylinder 14 passes through the bearing disc 11, and a transmission head 18 is provided between the outer cylinder 14 and the inner gear disc 17. The transmission head 18 meshes with the inner gear disc 17 and is connected to the outer cylinder 14. The upper end of the inner cylinder 15 passes through the outer gear disc 20 and the connecting pipe 12. A pressure handle 19 is connected between the inner cylinder 15 and the inner side of the outer gear disc 20, and a limit ring 27 is provided between the inner cylinder 15 and the connecting pipe 12. A brake motor 5 is fixed on the brake seat 2, and a transmission gear disc 13 is connected to the lower end of the brake motor 5. A transmission toothed belt surrounds the transmission gear disc 13 and the outer gear disc 20. Figure 2 , Three, the collecting device drives the transmission gear disc 13 to rotate by braking the brake motor 5, and then drives the bearing disc 11 to rotate in the brake seat 2 by the belt transmission structure between the transmission gear disc 13 and the outer gear disc 20. When the bearing disc 11 rotates axially, the outer cylinder column 14 rotates relatively longitudinally along the surface thread direction and the rotation direction by the driving of the lower end inner gear disc 17 and the transmission head 18. The drilling and sampling of the rock-soil collecting site are realized by the rotating action of the outer cylinder column 14. During the drilling process, the rock-soil structure is collected and fixed by the cylindrical cavity in the outer cylinder column 14. On this basis, the inner cylinder column 15 rotates synchronously with the outer gear disc 20 and the pressing member 19 to rotate synchronously and further in the outer cylinder column 14. The inner cylinder column 15 further collects and fixes the rock-soil structure sample in the outer cylinder column 14 by the cylindrical cavity structure, and completes the drilling and collecting work of the collecting device. Compared with the existing rock-soil collecting method, the device realizes the drilling of the soil layer and the drilling and collecting of the rock-soil sample by combining the outer cylinder column 14 and the inner cylinder column 15. The rock-soil sample is stabilized by the outer cylinder column 14 and the inner cylinder column 15 twice during the drilling process, which avoids the damage of the drilling structure and the disturbed soil layer to the rock-soil structure during the drilling process, and avoids the trouble of multi-point horizontal sampling. Moreover, the collected soil sample is in a cylindrical structure, which is convenient for subsequent rock-soil detection work and improves the practicability of the collecting device.

[0035] Further, the inner side of the collecting cylinder 9 is protruded to form a convex ring 16, as shown in Figure 3 The convex ring 16 is arranged between the outer cylinder column 14 and the inner wall of the collecting cylinder 9. The structure of the convex ring 16 is matched with the outer spiral structure of the outer cylinder column 14, which can eliminate the adhered rock-soil in the surface spiral gap of the outer cylinder column 14 by the convex surface of the convex ring 16 during the drilling of the outer cylinder column 14, and avoid the limitation of the rotating structure.

[0036] Further, the upper and lower ends of the collecting cylinder 9 are sleeved with buffer disc seats 8, and the left and right sides between the two buffer disc seats 8 are penetrated by telescopic shafts 10, as shown in Figure 3 The collecting cylinder 9 buffers the longitudinal stress of the collecting cylinder 9 by the upper and lower distributed buffer disc seats 8 and the telescopic shafts 10 arranged between the buffer disc seats 8. The structure of the telescopic shaft 10 is based on the telescopic cylinder structure and telescopic principle in the prior art. The relative telescoping of the telescopic shaft 10 provides a longitudinal displacement for the longitudinal drilling work of the collecting cylinder 9 to stabilize the cylinder structure of the collecting cylinder 9.

[0037] The collecting box 3 includes a collecting pipe 21, an encapsulating box 23 and a cylinder holder 28. The collecting pipe 21 longitudinally penetrates through the middle part of the cylinder holder 28, and the encapsulating box 23 transversely penetrates through the middle part of the cylinder holder 28 to encapsulate the rock-soil sample in the collecting pipe 21.

[0038] Furthermore, an output column tube 6 is inserted into the top of the frame 28, and a collection tube 21 passes through the output column tube 6. The bottom end of the collection tube 21 is connected to the top end of the inner cylinder 15. The encapsulation box 23 includes an encapsulation motor 24 and an encapsulation ring frame 25. The encapsulation motor 24 and the encapsulation ring frame 25 are adjacent axial structures, and an encapsulation strip 26 is wrapped around the encapsulation motor 24 and the encapsulation ring frame 25. The encapsulation strip 26 is axially aligned with the collection tube 21. A control panel 22, serving as the control electromechanical terminal, is embedded on the surface of the collection box 3. Based on the above, when the collection device reaches the drilling depth required for soil and rock collection, the inner cylinder 15 and the outer cylinder 14 are retracted by the reverse braking of the brake motor 5. Figure 6 As shown, during the upward rotation of the inner cylinder 15, the docking collection tube 21 serves as the transfer pipeline for the soil and rock samples within the inner cylinder 15. The limiting ring 27 acts as a limiting structure at the end of the inner cylinder 15. During upward rotation, the sealing motor 24 brakes, causing the sealing tape 26 to rotate along the outer edge of the sealing ring frame 25. The sealing tape 26 can be made of waxed paper used for soil and rock sealing. After one end of the sealing tape 26 is glued and wrapped around the edge of the soil and rock sample, the upward-rotating soil and rock sample will wrap around the surface of the sample in conjunction with the encircling movement of the sealing tape 26, thus sealing the sample. This prevents damage to the soil structure caused by external forces during subsequent sample collection. The sealing output of this collection device facilitates the subsequent transport and use of the soil and rock samples, further improving the practicality of the collection device.
